The Pristine Future: Why Science Fiction Abandons Oil and Fossil Fuels

The future is clean because all the oil is gone

In the realm of science fiction, visions of the future often gleam with pristine, utopian landscapes and gleaming cities.

One striking commonality among these futuristic portrayals is the conspicuous absence of oil and fossil fuels, the once-dominant energy sources of our present.

But why do sci-fi creators consistently envision a world where such primitive methods have been left behind? The answer lies in the belief that advanced technology and futuristic civilizations would never rely on such archaic energy sources.

The Dawn of Futuristic Energy

In the world of science fiction, the distant future is synonymous with breathtaking technological advancements.

Spacecraft traverse galaxies with ease, cities float in the sky, and robots perform intricate tasks effortlessly. In these fantastical worlds, oil and fossil fuels appear as relics of the past, resigned to the history books of an era long gone.

The driving force behind this visionary shift lies in the very essence of futuristic technology.

Science fiction writers and filmmakers envision advanced civilizations with highly sophisticated energy solutions that surpass the limitations of oil and fossil fuels. The idea is that such primitive methods, while once integral to our world, would be rendered obsolete by superior alternatives.

The Limitations of Oil and Fossil Fuels

Science fiction creators recognize the inherent shortcomings of oil and fossil fuels as energy sources. These resources are finite and subject to depletion, leading to resource wars and geopolitical tensions in our present reality.

They emit greenhouse gases, contributing to climate change and environmental degradation. In contrast, the future they imagine necessitates cleaner, more sustainable energy solutions to ensure the survival and prosperity of advanced civilizations.

Furthermore, the imaginative worlds of science fiction are driven by concepts like interstellar travel and space exploration. These endeavors demand extraordinary amounts of energy, making the reliance on oil and fossil fuels simply impractical.

For the creators of sci-fi, such primitive methods would be incapable of powering the fantastic technological marvels required to explore the cosmos.

The Paradigm Shift: Futuristic Energy Solutions

Science fiction offers a glimpse into the potential of renewable and advanced energy sources.

In these visionary worlds, technologies like antimatter reactors, fusion power, zero-point energy, or even harnessing energy from celestial bodies are imagined as the primary means of powering civilizations.

These theoretical energy sources, while still speculative in our present time, are perceived as the logical progression beyond our current reliance on oil and fossil fuels.

Moreover, as the genre explores themes of progress and evolution, it assumes that futuristic civilizations would have unlocked the secrets of limitless, sustainable energy.

By embracing these advanced energy solutions, the sci-fi future avoids the pitfalls of pollution, environmental degradation, and resource scarcity.

Reflections and Aspirations

Beyond technological feasibility, the futuristic portrayal of clean energy also reflects our collective aspirations for a better world.

Science fiction often serves as a mirror to society, reflecting our hopes and dreams for the future. By depicting advanced civilizations free from the shackles of fossil fuels, sci-fi inspires a collective longing for a more sustainable and harmonious existence.

In essence, science fiction presents a vision of a world where human ingenuity has transcended the limitations of our present reality.

The rejection of oil and fossil fuels in these fictional realms becomes a symbolic representation of our yearning for a cleaner, brighter future—one where technology coexists with nature in harmony.

An urgent meaning for today

While science fiction may currently be a realm of imagination, its vision of a future free from oil and fossil fuels serves as an inspiration and a call to action for our own world.

As we grapple with the challenges of climate change and the urgency to transition to renewable energy, these futuristic dreams remind us that there is a path beyond our dependence on finite resources.

The shift to cleaner energy solutions is not a distant fantasy; it is an attainable reality that requires dedication, innovation, and global cooperation.

By drawing on the visions of science fiction, we can fuel our determination to build a sustainable future—one where the landscapes are pristine, and the energy that powers our world aligns with the marvels of the imagination.

Only then can we take confident steps toward turning the clean energy dreams of science fiction into the breathtaking reality of our own future.

What’s an Atmospheric River and Why is California Lovin’ It?

Drought that looked invincible has met extreme opposite weather: stalemate?

Atmospheric river storms can actually be welcome in California during a historic drought, like the one this year. In some cases, nearly 50% of California’s precipitation each year can be the result of atmospheric rivers, and they can bring enough water to stop even a historic drought in its tracks.

Atmospheric river storms, also known as “pineapple express” storms, have sometimes been known to bring much-needed rain and snow to drought-stricken areas, including California.

Extreme weather, wildfires, and more have been on the increase worldwide as a result of global warming and climate change.

Atmospheric river storms are characterized by a narrow corridor of strong winds and heavy precipitation that can extend for thousands of miles. They are often associated with the transport of moist air from tropical regions, and they can be a significant source of water for many areas.

In California, atmospheric river storms can provide a much-needed source of water for agriculture, hydroelectric power generation, and other important water-dependent activities.

They can also help to replenish reservoirs and groundwater aquifers, which can help to mitigate the impacts of drought.

The monumental drought of 2022 in the rearview?

Just as it was looking as if there was zero chance for enough moisture to reverse the long, intense drought conditions that California has suffered this year, the “Pineapple Express” became a holiday storm front. There is a sense of relief, although it is too early to tell if the drought will end as a result of this rain.

It is also important to note that these storms can also bring heavy rainfall and strong winds, which can lead to flooding and other hazards. As a result, it is important for people in affected areas to be prepared and take necessary precautions.

An atmospheric river is a narrow band of moisture-rich air that extends from the tropics or subtropics to higher latitudes. These rivers of air are typically about a thousand miles wide and several thousand miles long, and they can transport enormous amounts of water vapor from the tropics to other parts of the world.

Atmospheric rivers are important because they play a crucial role in the global water cycle.

Water evaporates from the surface of the ocean, rises into the atmosphere, and then condenses to form clouds. As the clouds move over land, they release their moisture in the form of rain or snow.

Atmospheric rivers are responsible for a large portion of the moisture that falls as precipitation in many parts of the world, particularly along the western coasts of the United States, Europe, and Asia.

Atmospheric rivers can be either warm or cold, depending on the temperature of the air that they are carrying.

Warm atmospheric rivers are typically associated with heavy rainfall and floods, while cold atmospheric rivers can bring snow and ice to colder regions.

One of the most well-known atmospheric rivers is the “Pineapple Express,” which is a warm atmospheric river that brings moist air from the tropics to the Pacific Northwest of the United States.

The Pineapple Express is named after the tropical fruit because it brings warm, tropical air to the region. This atmospheric river is responsible for a large portion of the precipitation that falls in the Pacific Northwest, and it can cause heavy rainfall and floods in the region.

Another well-known atmospheric river is the “North Atlantic Oscillation,” which is a cold atmospheric river that brings moist air from the subtropics to the northeastern United States and eastern Canada.

This atmospheric river is responsible for a large portion of the snowfall that falls in these regions, and it can cause heavy snow and ice storms.

Atmospheric rivers can have a significant impact on the weather and climate of the regions that they affect.

They can bring much-needed moisture to dry regions, which can help to alleviate drought conditions. However, they can also cause heavy rainfall and floods, which can lead to damage to infrastructure and loss of life.

In recent years, there has been an increasing awareness of the importance of atmospheric rivers and their potential impact on the global water cycle.

Scientists are working to better understand atmospheric rivers and to develop better tools for predicting and managing their effects.

This research is important because atmospheric rivers are likely to become more intense and more frequent in the future due to climate change.

Generally speaking, an atmospheric river is a narrow band of moisture-rich air that extends from the tropics or subtropics to higher latitudes.

These rivers of air play a crucial role in the global water cycle and can bring much-needed moisture to dry regions or cause heavy rainfall and floods.

There is an increasing awareness of the importance of atmospheric rivers and their potential impact on the global water cycle, and scientists are working to better understand and predict their effects.

Fight Climate Emergency by Nationalizing US Fossil Fuel Industry, Says Top Economist

“If we are finally going to start taking the IPCC’s findings seriously, it follows that we must begin advancing far more aggressive climate stabilization solutions than anything that has been undertaken thus far,” writes Robert Pollin.

In the wake of a United Nations report that activists said showed the “bleak and brutal truth” about the climate emergency, a leading economist on Friday highlighted a step that supporters argue could be incredibly effective at combating the global crisis: nationalizing the U.S. fossil fuel industry.

“With at least ExxonMobil, Chevron, and ConocoPhillips under public control, the necessary phaseout of fossil fuels as an energy source could advance in an orderly fashion.”

Writing for The American Prospect, Robert Pollin, an economics professor and co-director of the Political Economy Research Institute at the University of Massachusetts Amherst, noted the Intergovernmental Panel on Climate Change (IPCC) and high gas prices exacerbated by Russia’s war on Ukraine.

“If we are finally going to start taking the IPCC’s findings seriously,” Pollin wrote, “it follows that we must begin advancing far more aggressive climate stabilization solutions than anything that has been undertaken thus far, both within the U.S. and globally. Within the U.S., such measures should include at least putting on the table the idea of nationalizing the U.S. fossil fuel industry.”

“With at least ExxonMobil, Chevron, and ConocoPhillips under public control, the necessary phaseout of fossil fuels as an energy source could advance in an orderly fashion”

Asserting that “at least in the U.S., the private oil companies stand as the single greatest obstacle to successfully implementing” a viable climate stabilization program, Pollin made the case that fossil fuel giants should not make any more money from wrecking the planet, nationalization would not be an unprecedented move in the United States, and doing so could help build clean energy infrastructure at the pace that scientists warn is necessary.

The expert proposed starting with “the federal government purchasing controlling ownership of at least the three dominant U.S. oil and gas corporations: ExxonMobil, Chevron, and ConocoPhillips.”

“They are far larger and more powerful than all the U.S. coal companies combined, as well as all of the smaller U.S. oil and gas companies,” he wrote. “The cost to the government to purchase majority ownership of these three oil giants would be about $420 billion at current stock market prices.

Emphasizing that the aim of private firms “is precisely to make profits from selling oil, coal, and natural gas, no matter the consequences for the planet and regardless of how the companies may present themselves in various high-gloss, soft-focus PR campaigns,” Pollin posited that “with at least ExxonMobil, Chevron, and ConocoPhillips under public control, the necessary phaseout of fossil fuels as an energy source could advance in an orderly fashion.”

“The government could determine fossil fuel energy production levels and prices to reflect both the needs of consumers and the requirements of the clean-energy transition,” he explained. “This transition could also be structured to provide maximum support for the workers and communities that are presently dependent on fossil fuel companies for their well-being.”

Pollin pointed out that some members of Congress are pushing for a windfall profits tax on Big Oil companies using various global crises—from Russia’s war to the ongoing Covid-19 pandemic—to price gouge working people at the gas pump. The proposal, he wrote, “raises a more basic question: Should the fossil fuel companies be permitted to profit at all through selling products that we know are destroying the planet? The logical answer has to be no. That is exactly why nationalizing at least the largest U.S. oil companies is the most appropriate action we can take now, in light of the climate emergency.”

The economist highlighted the long history of nationalizing in the United States, pointing out that “it was only 13 years ago, in the depths of the 2007–09 financial crisis and Great Recession, that the Obama administration nationalized two of the three U.S. auto companies.”

In addition to enabling the government to put the nationalized firms’ profits toward a just transition to renewables, Pollin wrote, “with nationalization, the political obstacles that fossil fuel companies now throw up against public financing for clean energy investments would be eliminated.”

Nationalization “is not a panacea,” Pollin acknowledged. Noting that “publicly owned companies already control approximately 90% of the world’s fossil fuel reserves,” he cautioned against assuming such a move in the U.S. “will provide favorable conditions for fighting climate change, any more than public ownership has done so already in Russia, Saudi Arabia, China, or Iran,” without an administration dedicated to tackling the global crisis.

Pollin is far from alone in proposing nationalization. Writing for Jacobin last month, People’s Policy Project founder Matt Bruenig argued that “an industry that is absolutely essential to maintain in the short term and absolutely essential to eliminate in the long term is an industry that really should be managed publicly.”

“Private owners and investors are not in the business of temporarily propping up dying industries, which means that they will either work to keep the industry from dying, which is bad for the climate, or that they will refuse to temporarily prop it up, which will cause economic chaos,” he wrote. “A public owner is best positioned to pursue managed decline in a responsible way.”

In a piece for The New Republic published in the early stage of the pandemic a few years ago, climate journalist Kate Aronoff—like Pollin on Friday—pointed out that nationalization “has a long and proud tradition of navigating America through times of crisis, from World War II to 9/11.”

As Aronoff—who interviewed New College of Florida economist Mark Paul—reported in March 2020:

In a way, nationalization would merely involve the government correcting for nearly a century of its own market intervention. All manner of government hands on the scales have kept money flowing into fossil fuels, including the roughly $26 billion worth of state and federal subsidies handed out to them each year. A holistic transition toward a low-carbon economy would reorient that array of market signals away from failing sectors and toward growing ones that can put millions to work right away retrofitting existing buildings to be energy efficient and building out a fleet of electric vehicles, for instance, including in the places that might otherwise be worst impacted by a fossil fuel bust and recession. Renewables have taken a serious hit amid the Covid-19 slowdown, too, as factories shut down in China. So besides direct government investments in green technology, additional policy directives from the federal level, Paul added, would be key to providing certainty for investors that renewables are worth their while: for example, low-hanging fruit like the extension of the renewable tax credits, now on track to be phased out by 2022.

While Pollin, Bruenig, and Aronoff’s writing focused on the United States, campaigners are also making similar cases around the world.

In a June 2021 opinion piece for The Guardian, Johanna Bozuwa, co-manager of the Climate & Energy Program at the Democracy Collaborative, and Georgetown University philosophy professor Olúfẹ́mi O Táíwò took aim at Royal Dutch Shell on the heels of a historic court ruling, declaring that “like all private oil companies, Shell should not exist.”

“Governments like the Netherlands could better follow through on mandates to reduce emissions if they held control over oil companies themselves,” the pair added. “It is time to nationalize Big Oil.”

The World Must Transition to 200% Renewable Energy Sources: no, that’s not a misprint

net-zero by 2050 was a joke, but nobody’s laughing

Attitude matters. Imagine that in the run-up to the 20xx Olympics your country declared: we will strive to not-lose and achieve net-zero gold medals!

OK maybe not the best metaphor but still – why aim to not trigger armageddon by… 2050?

  • It is international scientific consensus that, in order to prevent the worst climate damages, global net human-caused emissions of carbon dioxide (CO2) need to fall by about 45 percent from 2010 levels by 2030, reaching net zero around 2050. –

Once that lofty non-goal was agreed upon by governments across the globe, it quickly became apparent that virtually none of them were doing anywhere near what it would take to get to said uninspired non-goal.

The idea was (and still is) to drag and under-achieve as long as politically possible and then suddenly, in the final stretch, accelerate efforts (with resources controlled by future politicians) and reach net-zero. And then declare victory.

People want more than net-zero. People need more than net-zero. At the very least there has to be a better name, and a serious plan to make it actually happen.

You are going to hear a lot about minus-zero carbon soon. The reason is a good one. When the stakes are as high as the extinction of all life on earth, just getting to a tie score is not a good plan. So those who are in the trenches, working on solutions for global warming and reducing the carbon footprint, are search also for better ways to communicate what the goal is and what it means.

This, hopefully, can lead to a focus on a goal, or at least the articulation of a desire, that can inspire people to become highly active, even agitated, perhaps even alarmed, and begin the hard work and striving that it will take to get to a net-positive outcome for all of us.

And, who exactly decided that it would be a good idea to prolong the carbon carnival as long as possible in the first place? Carbon emitters and oil profiteers perhaps?

60 years of feet dragging, obfuscation and deliberate blocking of any solutions threatening the status quo have already come and gone.

Also, if energy is clean and abundant, why not use more? Energy is good, more energy use, if clean and sustainable, could be better. It can give us amazing things. Efficient use is good too, of course, but this is a mind-set issue. This is thought error or a thought liberation.

Minus-zero carbon x 100% (with 200% energy availability) is a much better goal and represents a thought liberating idea.

Perfection can’t be the enemy of good in the energy arena

Do we need architects and inventors, innovators and scientists, and massive amount of ammunition in the form of trillions of dollars in funding, from both public and private sources? Hell yes.

And must these magicians and Mavericks do amazing things that were believed impossible just a short while ago? Absolutely. Is this a ‘moon-shot’ to, not just save, but catapult humanity into a better future? You bet-ur-a%$ it is.

That means that the challenges of finding better tech, examples such as for soil regeneration, or more efficient battery storage, or for alternatives to rare earth metals, if they are too, um, rare need to be figured out and set into motion, fast. It means inventing and discovering tech that does not exist, that has not been tried or even sought after, why never sought? Because oil was cheap and available, so don’t stress it, Bub.

watch video

And, there are those out there, already today, that are thinking beyond net-zero in 2050. There are those that want more, that know that we need more. Those that understand that political inertia and corrupt vested interests are not the excuses we want written on our tombstones.

And why not look for half-full glasses or beliefs manifested into action? Why not aim for something that makes us want to get up, stand up, and make something possible that looks like hope and feels like success and winning?

Decentralized solutions are coming, in every part of life

The reality is that it is not only the world’s energy infrastructure that needs a total makeover. Financial inequality, political and economic systems are fragile and failing, regardless where.

There is a whiff of collapse that could turn into a whirlwind and then could derail any progress made, as we plunge into dark ages, even before factoring in the catastrophic climate challenges.

We need new, innovative ways to learn, to communicate, interact and collaborate. And these are emerging – if you don’t believe in crypto, web3 or any other new directions that many are seeing as alternatives to broken systems of the past, you at least have to acknowledge that actively looking for a better way, one that does represent a solution, is what is needed even as the current systems are failing us.

So if you don’t agree with the ideas for change and proposed ways to improve methods for human interaction and coexistence, come up with new ideas and put them forth, ok?, maybe we have to try and strive and stumble until a truly better way presents itself.

Give yourself and all you have into actions that will finally change the direction from one that spells doom, in this case continuing to burn carbon in insanely massive amounts while we fight, disagree and kill one another (war, etc.), to something new, something that at least could have a chance to win the peace.

Losing is unacceptable for-real this time. Winning isn’t everything, no sir, it’s the only thing. And starting on 04-22-2022 this net-zero BS needs to be sent to Mars, or perhaps Uranus.

Meanwhile here on earth we gotta get busy building the only thing that will prevent oblivion: a tiny taste of utopia that will grow from a seed into a raging forest of real, not fossilized, success.

The Real Dream of Clean Energy: Video Eureka Moment from Cleo Abram

Reducing fossil fuel use is important, but it’s more important to increase zero carbon energy production

Increasing sustainable energy production is possibly the most important goal for the world today. This idea is mostly couched, however, in negative terms, the idea that without a shift to clean, green sustainable sources climate change will destroy the future.

This is an important and essentially true statement.

However the automatic association of sustainable energy as being inevitably connected to less energy availability is a false premise. One that can be proven wrong with positive action towards building clean energy infrastructure, not as a defensive, desperate survival goal, but as a natural expansion of more energy and power that could lead to increased prosperity for the human race.

Deeply embedded thought patterns prevent us, perhaps, from imagining a world where more energy is not associated with more pollution, eventual depletion of a finite and limited resource and ultimately death, destruction and a CO2 induced climate catastrophe.

Optimism and abundance are linked with hope and a dream of a better standard of living for all. That dream is possible not with less energy use, but rather, more and cheaper energy availability that can be created by building a global, sustainable, renewable energy infrastructure.

A change in thought and perspective is necessary and could be more powerful than the sun

Utopia is a word that will get you laughed at, while oblivion is becoming the expected outcome of our century. Predicted by R. Buckminster Fuller in his book ‘Utopia or Oblivion‘, the choice we face in this century is not oblivion and catastrophic suffering or ‘business as usual’, it is not survival vs extinction, it is survival by unleashing utopian potential or total annihilation.

The paradox of sustainable energy is that, without it becoming the primary energy production system for the planet, combined with reduced consumption of fossil fuels until 100% sustainability is reached, oblivion or at least massive pain is assured; while at the same time, achieving 100% carbon free, clean energy from sustainable sources like solar, wind and geothermal, can create virtually unlimited increases in beneficial uses of energy, leading to an almost utopian potential for quality of life.

Thinking is the Difference Between Utopia or Oblivion

The clarity of realizing that clean sustainable energy ubiquity means unlimited energy consumption is non-destructive, and can end the malthusian nightmare of finite resources, that so many have fought over and even died for, is truly mind altering.

More is less, is another way to say it. Or at least more consumption and benefits, but none of the negative costs to the environment that we have come to see as inextricably linked to fossil fuel energy production and use.

At the same time it also harkens back to Elon Musk and Tesla’s mission statement. Tesla has had a vision for sustainable energy that is S3XY; more luxury, more beauty, more fun.

That mind-set, a mind set of abundant clean unlimited energy from sustainable sources, used to power beautiful powerful EVs, has made the company the enormous success that it is and ushered in an era EV production as job #1 throughout the entire auto industry.

The genius of this perspective centers on the idea that humans, when striving toward a positive goal, are always more powerful and successful than they are when simply trying to avoid a negative outcome.

Interestingly, the dream of reaching Mars, Musk’s other stated goal, is both positive and negative, since one reason for the urgent need to establish colonies there could be the destruction of earth due to climate disaster, caused by a failure to create a sustainable clean energy infrastructure in time.

It is the power and dream of much more abundant energy that can remove the idea from our minds that energy consumption is inherently bad, just because it does have negative ramifications galore when the source for that energy is dirty fossil fuels.

The Utopian Mindset must begin to permeate our consciousness if we are to overcome the challenges of 2000-2050 and beyond

Energy abundance is not the only type of abundance that our minds must learn to accept as possible for our species if we hope to turn things around. Bitcoin, for example, is currently being scapegoated in the media generally and is having endless disinformation hurled at its proof of work mining system based on the premise that it uses “too much” energy and too much of that energy is sourced from fossil fuels at this time.

But why not focus on the real problem? Why not see that a monumental and heroic effort to rid the world of dependence on “bad” and ultimately finite and limited sources of energy from fossil fuels and shift, ultimately, 100% of production to clean and renewable sources, needs to be job #1 for team earth?

Again, in an all-or-nothing scenario there is no option to equivocate. The negative reasons that fossil fuels must be phased out as soon as possible (‘the stick’ as per Cleo Abram in her video below) become more inevitable each minute and are already threatening everything humans have accomplished to date.

The positive motivation is less obvious for most at this point (‘the carrot’) and yet is ultimately more powerful (S3XY!) since it carries with it the hope that we can not only avert disaster, death and destruction, but can build a clean, abundant and infinitely expandable energy supply that could be used to build the first tentative steps toward a utopian dream.

6 months after the climate summit, where to find progress on climate change in a more dangerous and divided world

Six months ago, negotiators at the United Nations’ Glasgow climate summit celebrated a series of new commitments to lower global greenhouse gas emissions and build resilience to the impacts of climate change. Analysts concluded that the new promises, including phasing out coal, would bend the global warming trajectory, though still fall short of the Paris climate agreement.

Today, the world looks ever more complex. Russia is waging a war on European soil, with global implications for energy and food supplies. Some leaders who a few months ago were vowing to phase out fossil fuels are now encouraging fossil fuel companies to ramp up production.

In the U.S., the Biden administration has struggled to get its promised actions through Congress. Last-ditch efforts have been underway to salvage some kind of climate and energy bill from the abandoned Build Back Better plan. Without it, U.S. commitments to reduce emissions by over 50% by 2030 look fanciful, and the rest of the world knows it – adding another blow to U.S. credibility overseas.

Meanwhile, severe famines have hit Yemen and the Horn of Africa. Extreme heat has been threatening lives across India and Pakistan. Australia faced historic flooding, and the Southwestern U.S. can’t keep up with the wildfires.

As a former senior U.N. official, I’ve been involved in international climate negotiations for several years. At the halfway point of this year’s climate negotiations, with the next U.N. climate conference in November 2022, here are three areas to watch for progress and cooperation in a world full of danger and division.

Crisis response with long-term benefits

Russia’s invasion of Ukraine has added to a triple whammy of food price, fuel price and inflationary spikes in a global economy still struggling to emerge from the pandemic.

But Russia’s aggression has also forced Europe and others to move away from dependence on Russian oil, gas and coal. The G7 – Canada, France, Germany, Italy, Japan, the U.K. and the U.S. – pledged on May 8, 2022, to phase out or ban Russian oil and accelerate their shifts to clean energy.

In the short term, Europe’s pivot means much more energy efficiency – the International Energy Agency estimates that the European Union can save 15%-20% of energy demand with efficiency measures. It also means importing oil and gas from elsewhere.

In the medium term, the answer lies in ramping up renewable energy.

There are issues to solve. As Europe buys up gas from other places, it risks reducing gas supplies relied on by other countries, and forcing some of those countries to return to coal, a more carbon-intense fuel that destroys air quality. Some countries will need help expanding renewable energy and stabilizing energy prices to avoid a backlash to pro-climate policies.

As the West races to renewables, it will also need to secure a supply chain for critical minerals and metals necessary for batteries and renewable energy technology, including replacing an overdependence on China with multiple supply sources.

Ensuring integrity in corporate commitments

Finance leaders and other private sector coalitions made headline-grabbing commitments at the Glasgow climate conference in November 2021. They promised to accelerate their transitions to net-zero emissions by 2050, and some firms and financiers were specific about ending financing for coal plants that don’t capture and store their carbon, cutting methane emissions and supporting ending deforestation.

Their promises faced cries of “greenwash” from many climate advocacy groups. Some efforts are now underway to hold companies, as well as countries, to their commitments.

A U.N. group chaired by former Canadian Environment Minister Catherine McKenna is now working on a framework to hold companies, cities, states and banks to account when they claim to have “net-zero” emissions. This is designed to ensure that companies that pledged last year to meet net-zero now say how, and on what scientific basis.

For many companies, especially those with large emissions footprints, part of their commitment to get to net-zero includes buying carbon offsets – often investments in nature – to balance the ledger. This summer, two efforts to put guardrails around voluntary carbon markets are expected to issue their first sets of guidance for issuers of carbon credits and for firms that want to use voluntary carbon markets to fulfill their net-zero claims. The goal is to ensure carbon markets reduce emissions and provide a steady stream of revenue for parts of the world that need finance for their green growth.

Climate change influencing elections

Climate change is now an increasingly important factor in elections.

French President Emmanuel Macron, trying to woo supporters of a candidate to his left and energize young voters, made more dramatic climate pledges, vowing to be “the first major nation to abandon gas, oil and coal.”

With Chile’s swing to the left, the country’s redrafted constitution will incorporate climate stewardship.

In Australia, Scott Morrison’s government – which supported opening one of the world’s largest coal mines at the same time the Australian private sector is focusing on renewable energy – faces an election on May 21, 2022, with heatwaves and extreme flooding fresh in voters’ minds. Brazil’s Jair Bolsonaro faces opponents in October who are talking about protecting the climate.

Elections are fought and won on pocketbook issues, and energy prices are high and inflation is taking hold. But voters around the world are also experiencing the effects of climate change firsthand and are increasingly concerned.

The next climate conference

Countries will be facing a different set of economic and security challenges when the next round of U.N. talks begins in November in Sharm el-Sheikh, Egypt, compared to the challenges they faced in Glasgow. They will be expected to show progress on their commitments while struggling for bandwidth, dealing with the climate emergency as an integral part of security, economic recovery and global health.

There is no time to push climate action out into the future. Every decimal point of warming avoided is an opportunity for better health, more prosperity and better security.

‘Our House Is Truly on Fire’: Earth Now Has 50% Chance of Hitting 1.5°C of Warming by 2026

“The 1.5°C figure is not some random statistic,” said the head of the World Meteorological Organization. “It is rather an indicator of the point at which climate impacts will become increasingly harmful for people and indeed the entire planet.”

The World Meteorological Organization warned Monday that the planet now faces a 50% chance of temporarily hitting 1.5°C of warming above pre-industrial levels over the next five years, another signal that political leaders—particularly those of the rich nations most responsible for carbon emissions—are failing to rein in fossil fuel use.

“For as long as we continue to emit greenhouse gases, temperatures will continue to rise.”

In 2015, by comparison, the likelihood of briefly reaching or exceeding 1.5°C of global warming over the ensuing five-year period was estimated to be “close to zero,” the WMO noted in a new climate update. The report was published amid a deadly heatwave on the Indian subcontinent that scientists say is a glimpse of what’s to come if runaway carbon emissions aren’t halted. Thus far, the heatwave has killed dozens in India and Pakistan.

Signatories to the Paris climate accord have agreed to act to limit the global average temperature increase to well below 2°C—preferably to 1.5°C—by the end of the century. Climate advocates have deemed the 1.5°C target “on life support” following world leaders’ refusal to commit to more ambitious action at the COP26 summit in Glasgow late last year.

“We are getting measurably closer to temporarily reaching the lower target of the Paris Agreement,” Petteri Taalas, the secretary-general of the WMO, said in a statement Monday. “The 1.5°C figure is not some random statistic. It is rather an indicator of the point at which climate impacts will become increasingly harmful for people and indeed the entire planet.”

“For as long as we continue to emit greenhouse gases, temperatures will continue to rise,” Taalas added. “And alongside that, our oceans will continue to become warmer and more acidic, sea ice and glaciers will continue to melt, sea level will continue to rise and, our weather will become more extreme. Arctic warming is disproportionately high and what happens in the Arctic affects all of us.”

Dr. Leon Hermanson, a climate expert at the U.K. Met Office who led the WMO report, stressed that a short-lived breach of the 1.5°C threshold would not mean that the world is guaranteed to fall short of the Paris accord’s most ambitious warming target, which climate experts and campaigners have long decried as inadequate.

Such a breach, however, would “reveal that we are edging ever closer to a situation where 1.5°C could be exceeded for an extended period,” said Hermanson.

The WMO’s latest research also estimates that there is a 93% chance that at least one year between 2022 and 2026 will be the warmest on record. Currently, 2016 and 2020 are tied for the top spot.

Even if global warming is limited to 1.5°C by 2100, countless people across the globe will still face devastating heatwaves, droughts, and other extreme weather, with the poor facing the worst consequences.

Meanwhile, key ecosystems could be damaged beyond repair in a 1.5°C hotter world. One recent study found that 99% of the world’s coral reefs would experience heatwaves that are “too frequent for them to recover” if the planet gets 1.5°C warmer compared to pre-industrial levels.

Scientists behind the latest Intergovernmental Panel on Climate Change (IPCC) report cautioned last month that if there’s to be any hope of keeping warming to 1.5°C or below by 2100, “it’s now or never.”

“Without immediate and deep emissions reductions across all sectors, it will be impossible,” said Jim Skea, co-chair of IPCC Working Group III.

New Climate Doc Premieres on Netflix as Youth Await Major Court Decision

The award-winning documentary titled YOUTH v GOV premiered globally on the streaming platform Netflix Friday as the youth plaintiffs featured in the film await a decision that could put their historic climate lawsuit on a path to trial.

“In under two hours, you get an inside look at nearly seven years of Juliana v. United States,” said Julia Olson, executive director and chief legal counsel at Our Children’s Trust, in a statement about the independent film. “And it’s not over. We are determined to get to trial because our young clients deserve to take the stand and have their evidence heard by a judge.”

The documentary—directed by scientist and filmmaker Christi Cooper—focuses on the federal suit filed in 2015 and its 21 plaintiffs. The Our Children’s Trust legal team, which represents the young people, argues that by contributing to the climate emergency, the U.S. government is violating their clients’ constitutional rights to life, liberty, and property, and failing to protect essential public trust resources.

Shortly after settlement negotiations between the  U.S. Department of Justice (DOJ) and attorneys for the Juliana youth ended without resolution last November, federal lawmakers and advocacy groups sent President Joe Biden and other leaders in his administration letters in support of the plaintiffs.

“The question now is whether the Biden administration will keep fighting tooth and nail to keep them silenced, and whether our courts will stand up for their constitutional rights,” Olson said Friday. “After 50 years of the government—both Democrats and Republicans—knowingly making the climate crisis worse, I’m not betting on partisan politics. But I do have faith in the judiciary.”

The plaintiffs—now ages 14 to 26—are waiting for a court to rule on a motion to amend their complaint, which could put the case on track for a trial.

Since talks with the DOJ concluded, climate scientists have reiterated warnings about the need for systemic changes on a global scale, Congress has failed to pass a package containing key climate measures, and Biden has facedcriticism for not taking executive action to address the planetary emergency.

“I think for a lot of young people right now, life is really scary, because we’ve never seen a moment like this in history, and our feelings about our life and our future [are] all because of choices that we had no participation in,” says 26-year-old Kelsey Juliana—the named plaintiff in the case—during the first two minutes of the film.

“And so the plaintiffs joined this case,” Juliana adds, “because we all know who’s to blame and what needs to be done.”

https://twitter.com/MarkRuffalo/status/1520092989564985344?s=20&t=aNOtJQZVA_KWn-I0lHWhNA

The Netflix release of the film—which has won over two dozen awards at film festivals worldwide—was met with excitement by climate action advocates.

“Put this on your must watch list this weekend!” tweeted the Wisconsin Environmental Health Network. “Let’s get this important documentary into Netflix’s trending now category!”

Noting that one of the plaintiffs—21-year-old Xiuhtezcatl Martinez—is based in Boulder, Matt Benjamin, a member of the Colorado city’s council, also highlighted the doc on Twitter.

“Make sure to check out this film streaming tonight on Netflix,” he said. “It’s inspirational. It’s emotional. It fills me with hope that our younger generations will take control of their future.”

A ‘100% renewables’ target might not mean what you think it means. An energy expert explains

In the global effort to transition from fossil fuels to clean energy, achieving a “100% renewables” electricity system is considered ideal.

Some Australian states have committed to 100% renewable energy targets, or even 200% renewable energy targets. But this doesn’t mean their electricity is, or will be, emissions free.

Electricity is responsible for a third of Australia’s emissions, and making it cleaner is a key way to reduce emissions in other sectors that rely on it, such as transport.

So it’s important we have clarity about where our electricity comes from, and how emissions-intensive it is. Let’s look at what 100% renewables actually implies in detail.

Is 100% renewables realistic?

Achieving 100% renewables is one way of eliminating emissions from the electricity sector.

It’s commonly interpreted to mean all electricity must be generated from renewable sources. These sources usually include solar, wind, hydro, and geothermal, and exclude nuclear energy and fossil fuels with carbon capture and storage.

But this is a very difficult feat for individual states and territories to try to achieve.

The term “net 100% renewables” more accurately describes what some jurisdictions — such as South Australia and the ACT — are targeting, whether or not they’ve explicitly said so.

These targets don’t require that all electricity people use within the jurisdiction come from renewable sources. Some might come from coal or gas-fired generation, but the government offsets this amount by making or buying an equivalent amount of renewable electricity.

A net 100% renewables target allows a state to spruik its green credentials without needing to worry about the reliability implications of being totally self-reliant on renewable power.

So how does ‘net’ 100% renewables work?

All east coast states are connected to the National Electricity Market (NEM) — a system that allows electricity to be generated, used and shared across borders. This means individual states can achieve “net 100% renewables” without the renewable generation needing to occur when or where the electricity is required.

Take the ACT, for example, which has used net 100% renewable electricity since October 2019.

The ACT government buys renewable energy from generators outside the territory, which is then mostly used in other states, such as Victoria and South Australia. Meanwhile, people living in ACT rely on power from NSW that’s not emissions-free, because it largely comes from coal-fired power stations.

This way, the ACT government can claim net 100% renewables because it’s offsetting the non-renewable energy its residents use with the clean energy it’s paid for elsewhere.

SA’s target is to reach net 100% renewables by the 2030s. Unlike the ACT, it plans to generate renewable electricity locally, equal to 100% of its annual demand.

At times, such as especially sunny days, some of that electricity will be exported to other states. At other times, such as when the wind drops off, SA may need to rely on electricity imports from other states, which probably won’t come from all-renewable sources.

So what happens if all states commit to net 100% renewable energy targets? Then, the National Electricity Market will have a de-facto 100% renewable energy target — no “net”.

That’s because the market is one entire system, so its only options are “100% renewables” (implying zero emissions), or “less than 100% renewables”. The “net” factor doesn’t come into it, because there’s no other part of the grid for it to buy from or sell to.

How do you get to “200% renewables”, or more?

It’s mathematically impossible for more than 100% of the electricity used in the NEM to come from renewable sources: 100% is the limit.

Any target of more than 100% renewables is a different calculation. The target is no longer a measure of renewable generation versus all generation, but renewable generation versus today’s demand.

Australia could generate several times more renewable energy than there is demand today, but still use a small and declining amount of fossil fuels during rare weather events. Shutterstock

Tasmania, for example, has legislated a target of 200% renewable energy by 2040. This means it wants to produce twice as much renewable electricity as it consumes today.

But this doesn’t necessarily imply all electricity consumed in Tasmania will be renewable. For example, it may continue to import some non-renewable power from Victoria at times, such as during droughts when Tasmania’s hydro dams are constrained. It may even need to burn a small amount of gas as a backup.

This means the 200% renewable energy target is really a “net 200% renewables” target.

Meanwhile, the Greens are campaigning for 700% renewables. This, too, is based on today’s electricity demand.

In the future, demand could be much higher due to electrifying our transport, switching appliances from gas to electricity, and potentially exporting energy-intensive, renewable commodities such as green hydrogen or ammonia.

Targeting net-zero emissions

These “more than 100% renewables” targets set by individual jurisdictions don’t necessarily imply all electricity Australians use will be emissions free.

It’s possible — and potentially more economical — that we would meet almost all of this additional future demand with renewable energy, but keep some gas or diesel capacity as a low-cost backstop.

This would ensure continued electricity supply during rare, sustained periods of low wind, low sun, and high demand, such as during a cloudy, windless week in winter.

The energy transition is harder near the end — each percentage point between 90% and 100% renewables is more expensive to achieve than the previous.

That’s why, in a recent report from the Grattan Institute, we recommended governments pursue net-zero emissions in the electricity sector first, rather than setting 100% renewables targets today.

For example, buying carbon credits to offset the small amount of emissions produced in a 90% renewable NEM is likely to be cheaper in the medium term than building enough energy storage — such as batteries or pumped hydro dams — to backup wind and solar at all times.

The bottom line is governments and companies must say what they mean and mean what they say when announcing targets. It’s the responsibility of media and pundits to take care when interpreting them.

Social Media Giants’ Climate Misinformation Policies Leave Users ‘In the Dark’: Report

“Despite half of U.S. and U.K. adults getting their news from social media, social media companies have not taken the steps necessary to fight industry-backed deception,” reads the report.

Weeks after the Intergovernmental Panel on Climate Change identified disinformation as a key driver of the planetary crisis, three advocacy groups published a report Wednesday ranking social media companies on their efforts to ensure users can get accurate data about the climate on their platforms—and found that major companies like Twitter and Facebook are failing to combat misinformation.

The report, titled In the Dark: How Social Media Companies’ Climate Disinformation Problem is Hidden from the Public and released by Friends of the Earth (FOE), Greenpeace, and online activist network Avaaz, detailed whether the companies have met 27 different benchmarks to stop the spread of anti-science misinformation and ensure transparency about how inaccurate data is analyzed.

“Despite half of U.S. and U.K. adults getting their news from social media, social media companies have not taken the steps necessary to fight industry-backed deception,” reads the report. “In fact, they continue to allow these climate lies to pollute users’ feeds.

The groups assessed five major social media platforms—Facebook, Twitter, YouTube, Pinterest, and TikTok—and found that the two best-performing companies, Pinterest and YouTube, scored 14 out of the 27 possible points.

As Common Dreams reported earlier this month, Pinterest has won praise from groups including FOE for establishing “clearly defined guidelines against false or misleading climate change information, including conspiracy theories, across content and ads.”

“One of the key objectives of this report is to allow for fact-based deliberation, discussion, and debate to flourish in an information ecosystem that is healthy and fair, and that allows both citizens and policymakers to make decisions based on the best available data.”

The company also garnered points in Wednesday’s report for being the only major social media platform to make clear the average time or views it allows for a piece of scientifically inaccurate content before it will take action to combat the misinformation and including “omission or cherry-picking” of data in its definition of mis- or disinformation.

Pinterest and YouTube were the only companies that won points for consulting with climate scientists to develop a climate mis- and disinformation policy.

The top-performing companies, however, joined the other firms in failing to articulate exactly how their misinformation policy is enforced and to detail how climate misinformation is prioritized for fact-checking.

“Social media companies are largely leaving the public in the dark about their efforts to combat the problem,” the report reads. “There is a gross lack of transparency, as these companies conceal much of the data about the prevalence of digital climate dis/misinformation and any internal measures taken to address its spread.”

Twitter was the worst-performing company, meeting only five of the 27 criteria.

“Twitter is not clear about how content is verified as dis/misinformation, nor explicit about engaging with climate experts to review dis/misinformation policies or flagged content,” reads the report. “Twitter’s total lack of reference to climate dis/misinformation, both in their policies and throughout their enforcement reports, earned them no points in either category.”

TikTok scored seven points, while Facebook garnered nine.

The report, using criteria developed by the Climate Disinformation Coalition, was released three weeks after NPR reported that inaccurate information about renewable energy sources has been disseminated widely in Facebook groups, and the spread has been linked to slowing progress on or shutting down local projects.

In rural Ohio, posts in two anti-wind power Facebook groups spread misinformation about wind turbines causing birth defects in horses, failing to reduce carbon emissions, and causing so-called “wind turbine syndrome” from low-frequency sounds—a supposed ailment that is not backed by scientific evidence. The posts increased “perceptions of human health and public safety risks related to wind” power, according to a study published last October in the journal Energy Research & Social Science.

As those false perceptions spread through the local community, NPRreported, the Ohio Power Siting Board rejected a wind farm proposal “citing geological concerns and the local opposition.”

Misinformation on social media “can really slow down the clean energy transition, and that has just as dire life and death consequences, not just in terms of climate change, but also in terms of air pollution, which overwhelmingly hits communities of color,” University of California, Santa Barbara professor Leah Stokes told NPR.

As the IPCC reported in its February report, “rhetoric and misinformation on climate change and the deliberate undermining of science have contributed to misperceptions of the scientific consensus, uncertainty, disregarded risk and urgency, and dissent.”

Wednesday’s report called on all social media companies to:

  • Establish, disclose, and enforce policies to reduce climate change dis- and misinformation;
  • Release in full the company’s current labeling, fact-checking, policy review, and algorithmic ranking systems related to climate change disinformation policies;
  • Disclose weekly reports on the scale and prevalence of climate change dis- and misinformation on the platform and mitigation efforts taken internally; and
  • Adopt privacy and data protection policies to protect individuals and communities who may be climate dis/misinformation targets.

“One of the key objectives of this report is to allow for fact-based deliberation, discussion, and debate to flourish in an information ecosystem that is healthy and fair, and that allows both citizens and policymakers to make decisions based on the best available data,” reads the report.

“We see a clear boundary between freedom of speech and freedom of reach,” it continues, “and believe that transparency on climate dis/misinformation and accountability for the actors who spread it is a precondition for a robust and constructive debate on climate change and the response to the climate crisis.”

Climate Change Books: Why 04-22-22 will mark the Beginning of a New Era in Human History

photo bookshop / Ingram / Lynxotic collage

For 50 years warnings have been ignored: now it will be actions and solutions that matter

As a child I was fascinated with the Geodesic Dome and other inventions, such as the Dymaxion Car by R. Buckminster Fuller. I devoured his books but one stood out in particular. ‘Utopia or Oblivion‘, an obscure title that was difficult to read due to the pregnant prose and the seemingly overwrought message ( and title), the text shocked my young mind.

Originally published in 1963, decades before my birth, is is now nearly 60 years since it came out. What was shocking to me, at the time I first read it, was that the warnings in the book, made abundantly and overtly clear in the title and body, were not heeded, and that basically after decades passed the issue of fossil fuels being a non-sustainable resource was virtually ignored, with prejudice.

In 1963 the ozone layer was for all practical purposes still intact. Climate change, and / or global warming, caused by massive carbon emissions and the whole nasty, familiar story of today, was not even a consideration.

It was enough to know, unequivocally, that oil and other fossil fuels were a finite resource, and therefore will one day run out, that made it imperative, according to Fuller, to begin the necessary journey to building a world without them.

A book written by a genius, scientist, innovator and sage

This book ‘did the math’ and the science and concluded that humankind (still called mankind in those days) would have two fates possible in the next century (our century, f.y.i.): Utopia or Oblivion. To understand why this is absolutely right, in my opinion, I recommend reading the 448 pages of the book, 8 times, as I have.

In the many years since I first read this, now 59 year old book, the only thing that has changed is that his predictions of a world where humanity would face extinction (or be rescued by the realization that utopia is possible once we, as a species, make it possible) are now more definitely certain than ever.

Elon Musk, someone who would likely agree with much of the science in the book, is trying to get the “light of human consciousness‘ to Mars, since Earth’s survival hangs in the balance.

In the years since the documentary “An Inconvenient Truth” (2006) was released, scores of scientists and world leaders have repeatedly warned of the increasing dangers, with actual occurrences and measurements producing evidence, mountains of evidence month by month. It has reached a point where, even in the USA which has the highest percentage of climate change skeptics, over 70% of the population, nevertheless, believes the threat is serious, important, and real.

Image: SAP/Qualtrics

Finally, nearly 60 years after R. Buckminster Fuller’s seminal work, there is a consensus in the world that this is a problem that must be solved.

Not something to debate or consider. Nothing to prove or produce evidence of in order to justify acting on, we all believe (as a majority) that the solutions must be found and the actions needed to implement those chances must be started immediately.

Some of us, for example anyone who read ‘Utopia or Oblivion’ during the last 59 years, or anyone who ‘did the math’ and understood that oil and fossil fuels are not, and never were, meant to be a permeant source of energy for humanity, are ready to act.

Therefore, this article, and many more you will have the opportunity to read in celebration of Earth Day 2022, is designed to invite you to act now, if only by reading and learning about the challenges we face.

And then, armed with knowledge and understanding, to begin today, on 04-22-2022, the first day of a new era in human history, the beginning of transition to the sustainable, clean energy era. Utopia, then must be achieved, in order to prevent Oblivion.

A major book about the future of the world, blending intellectual and natural history and field reporting into a powerful account of the mass extinction unfolding before our eyes Over the last half-billion years, there have been Five mass extinctions, when the diversity of life on earth suddenly and dramatically contracted. Scientists around the world are currently monitoring the sixth extinction, predicted to be the most devastating extinction event since the asteroid impact that wiped out the dinosaurs. This time around, the cataclysm is us. In prose that is at once frank, entertaining, and deeply informed, New Yorker writer Elizabeth Kolbert tells us why and how human beings have altered life on the planet in a way no species has before. Interweaving research in half a dozen disciplines, descriptions of the fascinating species that have already been lost, and the history of extinction as a concept, Kolbert provides a moving and comprehensive account of the disappearances occurring before our very eyes. She shows that the sixth extinction is likely to be mankind’s most lasting legacy, compelling us to rethink the fundamental question of what it means to be human.

How to Avoid a Climate Disaster

#1 NEW YORK TIMES BEST SELLER – In this urgent, authoritative book, Bill Gates sets out a wide-ranging, practical–and accessible–plan for how the world can get to zero greenhouse gas emissions in time to avoid a climate catastrophe.Bill Gates has spent a decade investigating the causes and effects of climate change. With the help of experts in the fields of physics, chemistry, biology, engineering, political science, and finance, he has focused on what must be done in order to stop the planet’s slide to certain environmental disaster. In this book, he not only explains why we need to work toward net-zero emissions of greenhouse gases, but also details what we need to do to achieve this profoundly important goal. He gives us a clear-eyed description of the challenges we face. Drawing on his understanding of innovation and what it takes to get new ideas into the market, he describes the areas in which technology is already helping to reduce emissions, where and how the current technology can be made to function more effectively, where breakthrough technologies are needed, and who is working on these essential innovations.

Finally, he lays out a concrete, practical plan for achieving the goal of zero emissions–suggesting not only policies that governments should adopt, but what we as individuals can do to keep our government, our employers, and ourselves accountable in this crucial enterprise. 
As Bill Gates makes clear, achieving zero emissions will not be simple or easy to do, but if we follow the plan he sets out here, it is a goal firmly within our reach.

The Great Derangement: Climate Change and the Unthinkable

Are we deranged? The acclaimed Indian novelist Amitav Ghosh argues that future generations may well think so. How else to explain our imaginative failure in the face of global warming? In his first major book of nonfiction since In an Antique Land, Ghosh examines our inability–at the level of literature, history, and politics–to grasp the scale and violence of climate change. 
The extreme nature of today’s climate events, Ghosh asserts, make them peculiarly resistant to contemporary modes of thinking and imagining. This is particularly true of serious literary fiction: hundred-year storms and freakish tornadoes simply feel too improbable for the novel; they are automatically consigned to other genres.

In the writing of history, too, the climate crisis has sometimes led to gross simplifications; Ghosh shows that the history of the carbon economy is a tangled global story with many contradictory and counterintuitive elements. Ghosh ends by suggesting that politics, much like literature, has become a matter of personal moral reckoning rather than an arena of collective action. But to limit fiction and politics to individual moral adventure comes at a great cost. The climate crisis asks us to imagine other forms of human existence–a task to which fiction, Ghosh argues, is the best suited of all cultural forms. His book serves as a great writer’s summons to confront the most urgent task of our time. 

No Planet B: A Teen Vogue Guide to the Climate Crisis

An urgent call for climate justice from Teen Vogue, one of this generation’s leading voices, using an intersectional lens – with critical feminist, indigenous, antiracist and internationalist perspectives. As the political classes watch our world burn, a new movement of young people is rising to meet the challenge of climate catastrophe. This book is a guide, a toolkit, a warning and a cause for hope.


I hope that this book embodies Teen Vogue’s motto of making young people feel seen and heard all over the world. I hope that it forces their parents, communities, loved ones, friends, and–most importantly–those in power to see that the health of our planet depends on how quickly and drastically we change our behaviors. I hope it forces them all to respond. –From the foreword by Teen Vogue editor-in-chief, Lindsay Peoples Wagner

The Uninhabitable Earth: Life After Warming

#1 NEW YORK TIMES BESTSELLER – “The Uninhabitable Earth hits you like a comet, with an overflow of insanely lyrical prose about our pending Armageddon.”–Andrew Solomon, author of The Noonday Demon

With a new afterwordIt is worse, much worse, than you think. If your anxiety about global warming is dominated by fears of sea-level rise, you are barely scratching the surface of what terrors are possible–food shortages, refugee emergencies, climate wars and economic devastation. An “epoch-defining book” (TheGuardian) and “this generation’s Silent Spring” (The Washington Post), The Uninhabitable Earth is both a travelogue of the near future and a meditation on how that future will look to those living through it–the ways that warming promises to transform global politics, the meaning of technology and nature in the modern world, the sustainability of capitalism and the trajectory of human progress. The Uninhabitable Earth is also an impassioned call to action. For just as the world was brought to the brink of catastrophe within the span of a lifetime, the responsibility to avoid it now belongs to a single generation–today’s. Praise for The Uninhabitable Earth“The Uninhabitable Earth is the most terrifying book I have ever read. Its subject is climate change, and its method is scientific, but its mode is Old Testament. The book is a meticulously documented, white-knuckled tour through the cascading catastrophes that will soon engulf our warming planet.”–Farhad Manjoo, The New York Times

These energy innovations could transform how we mitigate climate change, and save money in the process – 5 essential reads

Building solar panels over water sources is one way to both provide power and reduce evaporation in drought-troubled regions. Robin Raj, Citizen Group & Solar Aquagrid

Stacy Morford, The Conversation

To most people, a solar farm or a geothermal plant is an important source of clean energy. Scientists and engineers see that plus far more potential.

They envision offshore wind turbines capturing and storing carbon beneath the sea, and geothermal plants producing essential metals for powering electric vehicles. Electric vehicle batteries, too, can be transformed to power homes, saving their owners money and also reducing transportation emissions.

With scientists worldwide sounding the alarm about the increasing dangers and costs of climate change, let’s explore some cutting-edge ideas that could transform how today’s technologies reduce the effects of global warming, from five recent articles in The Conversation.

1. Solar canals: Power + water protection

What if solar panels did double duty, protecting water supplies while producing more power?

California is developing the United States’ first solar canals, with solar panels built atop some of the state’s water distribution canals. These canals run for thousands of miles through arid environments, where the dry air boosts evaporation in a state frequently troubled by water shortages.

“In a 2021 study, we showed that covering all 4,000 miles of California’s canals with solar panels would save more than 65 billion gallons of water annually by reducing evaporation. That’s enough to irrigate 50,000 acres of farmland or meet the residential water needs of more than 2 million people,” writes engineering professor Roger Bales of the University of California, Merced. They would also expand renewable energy without taking up farmable land.

Research shows that human activities, particularly using fossil fuels for energy and transportation, are unequivocally warming the planet and increasing extreme weather. Increasing renewable energy, currently about 20% of U.S. utility-scale electricity generation, can reduce fossil fuel demand.

Putting solar panels over shaded water can also improve their power output. The cooler water lowers the temperature of the panels by about 10 degrees Fahrenheit (5.5 Celsius), boosting their efficiency, Bales writes.

2. Geothermal power could boost battery supplies

For renewable energy to slash global greenhouse gas emissions, buildings and vehicles have to be able to use it. Batteries are essential, but the industry has a supply chain problem.

Most batteries used in electric vehicles and utility-scale energy storage are lithium-ion batteries, and most lithium used in the U.S. comes from Argentina, Chile, China and Russia. China is the leader in lithium processing.

Geologist and engineers are working on an innovative method that could boost the U.S. lithium supply at home by extracting lithium from geothermal brines in California’s Salton Sea region.

Brines are the liquid leftover in a geothermal plant after heat and steam are used to produce power. That liquid contains lithium and other metals such as manganese, zinc and boron. Normally, it is pumped back underground, but the metals can also be filtered out. https://www.youtube.com/embed/oYtyEVPGEU8?wmode=transparent&start=0 How lithium is extracted during geothermal energy production.

“If test projects now underway prove that battery-grade lithium can be extracted from these brines cost effectively, 11 existing geothermal plants along the Salton Sea alone could have the potential to produce enough lithium metal to provide about 10 times the current U.S. demand,” write geologist Michael McKibben of the University of California, Riverside, and energy policy scholar Bryant Jones of Boise State University.

President Joe Biden invoked the Defense Production Act on March 31, 2022, to provide incentives for U.S. companies to mine and process more critical minerals for batteries.

3. Green hydrogen and other storage ideas

Scientists are working on other ways to boost batteries’ mineral supply chain, too, including recycling lithium and cobalt from old batteries. They’re also developing designs with other materials, explained Kerry Rippy, a researcher with the National Renewable Energy Lab.

Concentrated solar power, for example, stores energy from the sun by heating molten salt and using it to produce steam to drive electric generators, similar to how a coal power plant would generate electricity. It’s expensive, though, and the salts currently used aren’t stable at higher temperature, Rippy writes. The Department of Energy is funding a similar project that is experimenting with heated sand. https://www.youtube.com/embed/fkX-H24Chfw?wmode=transparent&start=0 Hydrogen’s challenges, including its fossil fuel history.

Renewable fuels, such as green hydrogen and ammonia, provide a different type of storage. Since they store energy as liquid, they can be transported and used for shipping or rocket fuel.

Hydrogen gets a lot of attention, but not all hydrogen is green. Most hydrogen used today is actually produced with natural gas – a fossil fuel. Green hydrogen, in contrast, could be produced using renewable energy to power electrolysis, which splits water molecules into hydrogen and oxygen, but again, it’s expensive.

“The key challenge is optimizing the process to make it efficient and economical,” Rippy writes. “The potential payoff is enormous: inexhaustible, completely renewable energy.”

4. Using your EV to power your home

Batteries could also soon turn your electric vehicle into a giant, mobile battery capable of powering your home.

Only a few vehicles are currently designed for vehicle-to-home charging, or V2H, but that’s changing, writes energy economist Seth Blumsack of Penn State University. Ford, for example, says its new F-150 Lightning pickup truck will be able to power an average house for three days on a single charge.

How bidirectional charging allows EVs to power homes.

Blumsack explores the technical challenges as V2H grows and its potential to change how people manage energy use and how utilities store power.

For example, he writes, “some homeowners might hope to use their vehicle for what utility planners call ‘peak shaving’ – drawing household power from their EV during the day instead of relying on the grid, thus reducing their electricity purchases during peak demand hours.”

5. Capturing carbon from air and locking it away

Another emerging technology is more controversial.

Humans have put so much carbon dioxide into the atmosphere over the past two centuries that just stopping fossil fuel use won’t be enough to quickly stabilize the climate. Most scenarios, including in recent Intergovernmental Panel on Climate Change reports, show the world will have to remove carbon dioxide from the atmosphere, as well.

The technology to capture carbon dioxide from the air exists – it’s called direct air capture – but it’s expensive.

Engineers and geophysicists like David Goldberg of Columbia University are exploring ways to cut those costs by combining direct air capture technology with renewable energy production and carbon storage, like offshore wind turbines built above undersea rock formations where captured carbon could be locked away.

The world’s largest direct air capture plant, launched in 2021 in Iceland, uses geothermal energy to power its equipment. The captured carbon dioxide is mixed with water and pumped into volcanic basalt formations underground. Chemical reactions with the basalt turn it into a hard carbonate.

Goldberg, who helped developed the mineralization process used in Iceland, sees similar potential for future U.S. offshore wind farms. Wind turbines often produce more energy than their customers need at any given time, making excess energy available.

“Built together, these technologies could reduce the energy costs of carbon capture and minimize the need for onshore pipelines, reducing impacts on the environment,” Goldberg writes.

How fast can we stop Earth from warming?

The ocean retains heat for much longer than land does. photo / adobe stock / lynxotic

Richard B. (Ricky) Rood, University of Michigan

Global warming doesn’t stop on a dime. If people everywhere stopped burning fossil fuels tomorrow, stored heat would still continue to warm the atmosphere.

Picture how a radiator heats a home. Water is heated by a boiler, and the hot water circulates through pipes and radiators in the house. The radiators warm up and heat the air in the room. Even after the boiler is turned off, the already heated water is still circulating through the system, heating the house. The radiators are, in fact, cooling down, but their stored heat is still warming the air in the room.

This is known as committed warming. Earth similarly has ways of storing and releasing heat.

Emerging research is refining scientists’ understanding of how Earth’s committed warming will affect the climate. Where we once thought it would take 40 years or longer for global surface air temperature to peak once humans stopped heating up the planet, research now suggests temperature could peak in closer to 10 years.

But that doesn’t mean the planet returns to its preindustrial climate or that we avoid disruptive effects such as sea level rise.

I am a professor of climate science, and my research and teaching focus on the usability of climate knowledge by practitioners such as urban planners, public health professionals and policymakers. Let’s take a look at the bigger picture.

How understanding of peak warming has changed

Historically, the first climate models represented only the atmosphere and were greatly simplified. Over the years, scientists added oceans, land, ice sheets, chemistry and biology.

Today’s models can more explicitly represent the behavior of greenhouse gases, especially carbon dioxide. That allows scientists to better separate heating due to carbon dioxide in the atmosphere from the role of heat stored in the ocean. https://www.youtube.com/embed/_WUNMzC98jI?wmode=transparent&start=0 Why global warming is ocean warming.

Thinking about our radiator analogy, increasing concentrations of greenhouse gases in Earth’s atmosphere keep the boiler on – holding energy near the surface and raising the temperature. Heat accumulates and is stored, mostly in the oceans, which take on the role of the radiators. The heat is distributed around the world through weather and oceanic currents.

The current understanding is that if all of the additional heating to the planet caused by humans was eliminated, a plausible outcome is that Earth would reach a global surface air temperature peak in closer to 10 years than 40. The previous estimate of 40 or more years has been widely used over the years, including by me.

It is important to note that this is only the peak, when the temperature starts to stabilize – not the onset of rapid cooling or a reversal of climate change.

I believe there is enough uncertainty to justify caution about exaggerating the significance of the new research’s results. The authors applied the concept of peak warming to global surface air temperature. Global surface air temperature is, metaphorically, the temperature in the “room,” and is not the best measure of climate change. The concept of instantly cutting off human-caused heating is also idealized and entirely unrealistic – doing that would involve much more than just ending fossil fuel use, including widespread changes to agriculture – and it only helps illustrate how parts of the climate might behave.

Even if the air temperature were to peak and stabilize, “committed ice melting,” “committed sea level rise” and numerous other land and biological trends would continue to evolve from the accumulated heat. Some of these could, in fact, cause a release of carbon dioxide and methane, especially from the Arctic and other high-latitude reservoirs that are currently frozen.

For these reasons and others, it is important to consider the how far into the future studies like this one look.

Oceans in the future

Oceans will continue to store heat and exchange it with the atmosphere. Even if emissions stopped, the excess heat that has been accumulating in the ocean since preindustrial times would influence the climate for another 100 years or more.

Because the ocean is dynamic, it has currents, and it will not simply diffuse its excess heat back into the atmosphere. There will be ups and downs as the temperature adjusts.

The oceans also influence the amount of carbon dioxide in the atmosphere, because carbon dioxide is both absorbed and emitted by the oceans. Paleoclimate studies show large changes in carbon dioxide and temperature in the past, with the oceans playing an important role.

The chart shows how excess heat – thermal energy – has built up in ocean, land, ice and atmosphere since 1960 and moved to greater ocean depths with time. TOA CERES refers to the top of the atmosphere. Karina von Schuckman, LiJing Cheng, Matthew D. Palmer, James Hansen, Caterina Tassone, et al., CC BY-SA

Countries aren’t close to ending fossil fuel use

The possibility that a policy intervention might have measurable impacts in 10 years rather than several decades could motivate more aggressive efforts to remove carbon dioxide from the atmosphere. It would be very satisfying to see policy interventions having present rather than notional future benefits.

[Over 150,000 readers rely on The Conversation’s newsletters to understand the world. Sign up today.]

However, today, countries aren’t anywhere close to ending their fossil fuel use. Instead, all of the evidence points to humanity experiencing rapid global warming in the coming decades.

Our most robust finding is that the less carbon dioxide humans release, the better off humanity will be. Committed warming and human behavior point to a need to accelerate efforts both to reduce greenhouse gas emissions and to adapt to this warming planet now, rather than simply talking about how much needs to happen in the future.

A universe without mathematics is beyond the scope of our imagination

Mathematics is the language of the universe. (Shutterstock)

Peter Watson, Carleton University

Almost 400 years ago, in The Assayer, Galileo wrote: “Philosophy is written in this grand book, the universe … [But the book] is written in the language of mathematics.” He was much more than an astronomer, and this can almost be thought of as the first writing on the scientific method.

We do not know who first started applying mathematics to scientific study, but it is plausible that it was the Babylonians, who used it to discover the pattern underlying eclipses, nearly 3,000 years ago. But it took 2,500 years and the invention of calculus and Newtonian physics to explain the patterns. https://www.youtube.com/embed/Rx-5dCXx1SI?wmode=transparent&start=0 Science Magazine looks at Babylonian clay tablets that contained mathematical formulas that are a precursor to calculus.

Since then, probably every single major scientific discovery has used mathematics in some form, simply because it is far more powerful than any other human language. It is not surprising that this has led many people to claim that mathematics is much more: that the universe is created by a mathematician.

So could we imagine a universe in which mathematics does not work?

The language of mathematics

The Sapir-Whorf hypothesis asserts that you cannot discuss a concept unless you have the language to describe it.

In any science, and physics in particular, we need to describe concepts that do not map well on to any human language. One can describe an electron, but the moment we start asking questions like “What colour is it?” we start to realize the inadequacies of English.

The colour of an object depends on the wavelengths of light reflected by it, so an electron has no colour, or more accurately, all colours. The question itself is meaningless. But ask “How does an electron behave?” and the answer is, in principle, simple. In 1928, Paul A.M. Dirac wrote down an equation that describes the behaviour of an electron almost perfectly under all circumstances. This does not mean it is simple when we look at the details.

For example, an electron behaves as a tiny magnet. The magnitude can be calculated, but the calculation is horrendously complicated. Explaining an aurora, for example, requires us to understand orbital mechanics, magnetic fields and atomic physics, but at heart, these are just more mathematics.

But it is when we think of the individual that we realize that a human commitment to logical, mathematical thinking goes much deeper. The decision to overtake a slow-moving car does not involve the explicit integration of the equations of motion, but we certainly do it implicitly. A Tesla on autopilot will actually solve them explicitly.

When overtaking a car, a Tesla will explicitly calculate what a human driver processes implicitly. (Shutterstock)

Predicting chaos

So we really should not be surprised that mathematics is not just a language for describing the external world, but in many ways the only one. But just because something can be described mathematically does not mean it can be predicted.

One of the more remarkable discoveries of the last 50 years has been the discovery of “chaotic systems.” These can be apparently simple mathematical systems that cannot be solved precisely. It turns out that many systems are chaotic in this sense. Hurricane tracks in the Caribbean are superficially similar to eclipse tracks, but we cannot predict them precisely with all the power of modern computers.

However, we understand why: the equations that describe weather are intrinsically chaotic, so we can make accurate predictions in the short term, (about 24 hours), but these become increasingly unreliable over days. Similarly, quantum mechanics provides a theory where we know precisely what predictions cannot be made precisely. One can calculate the properties of an electron very accurately, but we cannot predict what an individual one will do.

Hurricanes are obviously intermittent events, and we cannot predict when one will happen in advance. But the mere fact that we cannot predict an event precisely does not mean we cannot describe it when it happens. We can even handle one-off events: it is generally accepted that the universe was created in the Big Bang and we have a remarkably precise theory of that.

Designing social systems

A whole host of social phenomena, from the stock market to revolutions, lack good predictive mathematics, but we can describe what has happened and to some extent construct model systems.

So how about personal relationships? Love may be blind, but relationships are certainly predictable. The vast majority of us choose partners inside our social class and linguistic group, so there is absolutely no doubt that is true in the statistical sense.

But it is also true in the local sense. A host of dating sites make their money by algorithms that at least make some pretence at matching you to your ideal mate. In a TED talk, futurist Amy Webb shows that mathematics actually works in dating algorithms.

A universe that could not be described mathematically would need to be fundamentally irrational and not merely unpredictable. Just because a theory is implausible does not mean we could not describe it mathematically.

But I do not think we live in that universe, and I suspect we cannot imagine a non-mathematical universe.

Cannabis: how it affects our cognition and psychology – new research

Cannabis has been used by humans for thousands of years and is one of the most popular drugs today. With effects such as feelings of joy and relaxation, it is also legal to prescribe or take in several countries.

But how does using the drug affect the mind? In three recent studies, published in The Journal of Psychopharmacology, Neuropsychopharmacology and the International Journal of Neuropsychopharmacology, we show that it can influence a number of cognitive and psychological processes.

The United Nations Office on Drugs and Crime reported that, in 2018, approximately 192 million people worldwide aged between 15 and 64 used cannabis recreationally. Young adults are particularly keen, with 35% of people between the ages of 18 and 25 using it, while only 10% of people over the age of 26 do.

This indicates that the main users are adolescents and young adults, whose brains are still in development. They may therefore be particularly vulnerable to the effects of cannabis use on the brain in the longer term.

Tetrahydrocannabinol (THC) is the main psychoactive compound in cannabis. It acts on the brain’s “endocannabinoid system”, which are receptors which respond to the chemical components of cannabis. The cannabis receptors are densely populated in prefrontal and limbic areas in the brain, which are involved in reward and motivation. They regulate signalling of the brain chemicals dopamine, gamma-aminobutyric acid (GABA) and glutamate.

We know that dopamine is involved in motivation, reward and learning. GABA and glutamate play a part in cognitive processes, including learning and memory.

Cognitive effects

Cannabis use can affect cognition, especially in those with cannabis-use disorder. This is characterised by the persistent desire to use the drug and disruption to daily activities, such as work or education. It has been estimated that approximately 10% of cannabis users meet the diagnostic criteria for this disorder.

In our research, we tested the cognition of 39 people with the disorder (asked to be clean on the day of testing), and compared it with that of 20 people who never or rarely used cannabis. We showed that participants with the condition had significantly worse performance on memory tests from the Cambridge Neuropsychological Test Automated Battery (CANTAB) compared to the controls, who had either never or very rarely used cannabis. It also negatively affected their “executive functions”, which are mental processes including flexible thinking.

This effect seemed to be linked to the age at which people started taking the drug – the younger they were, the more impaired their executive functioning was.

Cognitive impairments have been noted in mild cannabis users as well. Such users tend to make riskier decisions than others and have more problems with planning.

Although most studies have been conducted in males, there has been evidence of sex differences in the effects of cannabis use on cognition. We showed that, while male cannabis users had poorer memory for visually recognising things, female users had more problems with attention and executive functions. These sex effects persisted when controlling for age; IQ; alcohol and nicotine use; mood and anxiety symptoms; emotional stability; and impulsive behaviour.

Reward, motivation and mental health

Cannabis use can also affect how we feel – thereby further influencing our thinking. For example, some previous research has suggested that reward and motivation – along with the brain circuits involved in these processes – can be disrupted when we use cannabis. This may affect our performance at school or work as it can make us feel less motivated to work hard, and less rewarded when we do well.

In our recent study, we used a brain imaging task, in which participants were placed in a scanner and viewed orange or blue squares. The orange squares would lead to a monetary reward, after a delay, if the participant made a response. This set up helped us investigate how the brain responds to rewards.

We focused particularly on the ventral striatum, which is a key region in the brain’s reward system. We found that the effects on the reward system in the brain were subtle, with no direct effects of cannabis in the ventral striatum. However, the participants in our study were moderate cannabis users. The effects may be more pronounced in cannabis users with more severe and chronic use, as seen in cannabis use disorder.

There is also evidence that cannabis can lead to mental health problems. We have shown that it is related to higher “anhedonia” – an inability to feel pleasure – in adolescents. Interestingly, this effect was particularly pronounced during the COVID-19 pandemic lockdowns.

Cannabis use during adolescence has also been reported as a risk factor for developing psychotic experiences as well as schizophrenia. One study showed that cannabis use moderately increases the risk of psychotic symptoms in young people, but that it has a much stronger effect in those with a predisposition for psychosis (scoring highly on a symptom checklist of paranoid ideas and psychoticism).

Assessing 2,437 adolescents and young adults (14-24 years), the authors reported a six percentage points increased risk – from 15% to 21% – of psychotic symptoms in cannabis users without a predisposition for psychosis. But there was a 26-point increase in risk – from 25% to 51% – of psychotic symptoms in cannabis users with a predisposition for psychosis.

We don’t really know why cannabis is linked to psychotic episodes, but hypotheses suggests dopamine and glutamate may be important in the neurobiology of these conditions.

Another study of 780 teenagers suggested that the association between cannabis use and psychotic experiences was also linked to a brain region called the “uncus”. This lies within the parahippocampus (involved in memory) and olfactory bulb (involved in processing smells), and has a large amount of cannabinoid receptors. It has also previously been associated with schizophrenia and psychotic experiences.

Cognitive and psychological effects of cannabis use are ultimately likely to depend to some extent on dosage (frequency, duration and strength), sex, genetic vulnerabilities and age of onset. But we need to determine whether these effects are temporary or permanent. One article summarising many studies has suggested that with mild cannabis use, the effects may weaken after periods of abstinence.

But even if that’s the case, it is clearly worth considering the effects that prolonged cannabis use can have on our minds – particularly for young people whose brains are still developing.

Why do cats’ eyes glow in the dark?

Curious Kids is a series for children of all ages. If you have a question you’d like an expert to answer, send it to curiouskidsus@theconversation.com.


Why do cats’ eyes glow in the dark? Chloe, age 10, Barkhamsted, Connecticut


Cats and many other animals, including most dogs, can reflect light from their eyes. That’s why cats’ eyes will usually shine brightly in photos taken in a dimly lit room or glow when illuminated in the dark by a flashlight or a car’s headlights.

Species whose eyes glow have evolved to see better in low light because they either forage or need to look out for predators throughout the night, or they do most of their hunting at dawn and dusk. In fact, domesticated cats can see in conditions that are only 16% as bright as what people require.

Cats accomplish this because their pupils – the openings that appear black in the middle of their eyes that widen and narrow in response to light conditions – are special. Pupils operate like windows, with bigger ones letting more light into the eye. And a cat’s pupils can become up to 50% larger than human pupils in dim light. They also have a higher number of a specific type of light-sensing cell in the back of their eyes than we do. These cells, called rods, catch low-level light.

The tapetum lucidum

In addition to having large pupils and lots of rods, cats have something people don’t: a tapetum lucidum, a Latin medical term that translates to “bright or shining tapestry.” The tapetum lucidum is also known as “eyeshine.”

It’s located in the back of the eye behind the retina – a thin layer of tissue that receives light, converts the light to an electrical signal and sends this signal to the brain to interpret the image.

A cat’s tapetum lucidum is made up of cells with crystals that, like a mirror, reflect light back to the retina. This gives the retina a second chance to absorb more light.

The feline tapetum lucidum is special because its reflective compound is riboflavin, a type of vitamin B. Riboflavin has unique properties that amplify light to a specific wavelength that cats can see well, which greatly increases the sensitivity of the retina to low light.

In cats, the tapetum most often glows yellow-green or yellow-orange, but the color varies, just like their irises – the colorful part of their eye, which can be green, yellow, blue or golden. Variation in tapetum color is not unique to cats and can be found in lots of species.

Most dogs’ eyes will glow in dark spaces when a light shines on them. Tommy Greco, CC BY-SA

Other animals’ eyes glow too

Many other animals that need to see at night have a tapetum lucidum. That includes predators and prey alike, everything from wild foxes to farmed sheep and goats.

The tapetum lucidum is also useful to fish, dolphins and other aquatic animals, because it helps them see better in murky, dark water.

In land animals, the tapetum is found in the top half of the eye behind the retina, because they need to see what is on the ground best. But in aquatic animals the tapetum takes up most of the eye, because they need to see all around them in the dark.

Like cats, the lemur, a small primate, and its close relative, the bush baby – also known as a “night monkey” – also have a superreflective tapetum made with riboflavin.

Even though a lot of animals have eyeshine, some small domesticated dogs lack this trait. Most animals with blue eyes and white or light-colored coats have also lost this trait.

So don’t be alarmed if your dog’s or cat’s eyes don’t glow. The list of other species without a tapetum lucidum includes pigs, birds, reptiles and most rodents and primates – including humans.

Is there a downside?

Unfortunately, animals with a tapetum lucidum sacrifice some visual acuity for their ability to see in dim light.

That’s because all that light bouncing around as it reflects off the tapetum can make what they see a little fuzzier. So, a cat needs to be seven times closer to an object to see it as sharply as a person would in a brightly lit place.

But don’t worry, I’m sure your cat would rather see clearly at night than read a book.

Study Exposes How World’s Biggest Corporations Embellish Climate Progress

Above: Photo / Collage / Lynxotic / Adobe Stock

Without more regulation, this will continue,” said one critic. “We need governments and regulatory bodies to step up and put an end to this greenwashing trend.”

A new study out Monday evaluates the public climate pledges made by 25 of the world’s biggest corporations and concludes they “cannot be taken at face value” because the vast majority of firms analyzed are exaggerating the nature of and progress toward their goals—a greenwashing trend that critics say will continue in the absence of stronger regulation.

“Setting vague targets will get us nowhere without real action, and can be worse than doing nothing if it misleads the public.”

Providing further evidence of the fallacies of “net-zero,”the Corporate Climate Responsibility Monitor 2022 finds that net-zero pledges made by several of the world’s largest companies aim to reduce aggregate greenhouse gas emissions across their full value chains by only 40%, at most, from 2019 levels—a far cry from the 100% implied when they claim to be pursuing “carbon neutrality.”

According to the assessment conducted by NewClimate Insitute in collaboration with Carbon Market Watch, just one company’s net-zero pledge was determined to have “reasonable integrity.” Three were deemed to have “moderate integrity,” 10 “low integrity,” and the remaining 11 “very low integrity.”

“We set out to uncover as many replicable good practices as possible, but we were frankly surprised and disappointed at the overall integrity of the companies’ claims,” lead author Thomas Day of NewClimate Institute said in a statement.

“As pressure on companies to act on climate change rises, their ambitious-sounding headline claims all too often lack real substance, which can mislead both consumers and the regulators that are core to guiding their strategic direction,” said Day. “Even companies that are doing relatively well exaggerate their actions.”

The analysis turned up zero pledges with “high integrity.” Maersk came out on top, with “reasonable integrity,” followed by Apple, Sony, and Vodafone with “moderate integrity.”

Meanwhile, the headline pledges of Amazon, Deutsche Telekom, Enel, GlaxoSmithKline, Google, Hitachi, IKEA, Vale, Volkswagen, and Walmart were rated as having “low integrity.” Those of Accenture, BMW Group, Carrefour, CVS Health, Deutsche Post DHL, E.ON SE, JBS, Nestlé, Novartis, Saint-Gobain, and Unilever were considered to have “very low integrity.”

Although all 25 companies examined in the report establish “some form of zero-emission, net-zero, or carbon-neutral target,” the authors note, just three companies—Maersk, Vodafone, and Deutsche Telekom—make clear commitments to decarbonizing 90% of their entire value chains.

By contrast, at least five companies would effectively decrease their emissions by less than 15%, often by excluding “upstream or downstream emissions”—pollution generated by activities indirectly linked to a company.

Day told The Guardian that “it’s short-term action that’s the most important thing, in the climate crisis.”

Nevertheless, noted the British newspaper, “the report show[s] that the companies surveyed would only cut their emissions by about 23% on average by 2030, falling far short of the figure of nearly halving in the next decade that scientists say is needed to limit global heating to 1.5ºC.”

Despite the damning findings, some companies doubled down on their claims of progress. In a statement shared with BBC, Amazon said: “We set these ambitious targets because we know that climate change is a serious problem, and action is needed now more than ever. As part of our goal to reach net-zero carbon by 2040, Amazon is on a path to powering our operations with 100% renewable energy by 2025.”

However, Amazon is one of several companies that have donated to right-wing Democratic Sens. Kyrsten Sinema (Ariz.) and Joe Manchin (W.Va.), who teamed up with the GOP to torpedo the Build Back Better Act—a piece of legislation that, among other things, would have accelerated the clean energy transition.

According to climate justice advocates, net-zero pledges are inadequate because they are “premised on the notion of canceling out emissions in the atmosphere rather than eliminating their causes.” Because the practice enables powerful entities to continue with business as usual in some places as long as they fund projects that purportedly slash pollution in other places, there is little to no evidence that overall emissions will be sufficiently reduced.

The new study shows how several corporations are inflating the extent of their ambition and progress by taking advantage of ambiguous terms like net-zero and carbon-neutral and by disregarding upstream or downstream emissions.

“Many company pledges are undermined by contentious plans to reduce emissions elsewhere, hidden critical information, and accounting tricks,” states a summary of the report. It continues:

The exclusion of emission sources or market segments is a common issue that reduces the meaning of targets. Eight companies exclude upstream or downstream emissions in their value chain, which usually account for over 90% of the emissions under their control. E.ON may exclude market segments that account for more than 40% of its energy sales; Carrefour appears to exclude locations that account for over 80% of Carrefour branded stores.

24 of 25 companies will likely rely on offsetting credits, of varying quality. At least two-thirds of the companies rely on removals from forests and other biological activities, which can easily be reversed by, for example, a forest fire. Nestlé and Unilever distance themselves from the practice of offsetting at the level of the parent company, but allow and encourage their individual brands to pursue offsetting to sell carbon-neutral labeled products.

Some apparently ambitious targets may lead to very little short-term action. It may be possible for CVS Health to achieve their 2030 emission reduction target with limited additional action, since the target is compared to a base year with extraordinarily high emissions. GlaxoSmithKline may delay the implementation of key emission reduction measures until 2028/2029, ahead of its 2030 target.

As The Guardian reported, “Day said using offsetting tended to obscure whether companies were making genuine progress on cutting their own emissions, or hiding behind offsets to achieve a notional net-zero.”

“It’s better practice not to offset—it’s more transparent and constructive,” said the researcher. “Companies should not be claiming they are net-zero by 2030 unless they are reducing their emissions by 90% by then.”

The failure of so-called “corporate social responsibility” initiatives to deliver on promises to improve the well-being of workers and ecosystems is a longstanding pattern, which is why many progressive critics have called them public relations gimmicks.

According to the new report: “The rapid acceleration of corporate climate pledges, combined with the fragmentation of approaches means that it is more difficult than ever to distinguish between real climate leadership and unsubstantiated greenwashing. This is compounded by a general lack of regulatory oversight at national and sectoral levels. Identifying and promoting real climate leadership is a key challenge that, where addressed, has the potential to unlock greater global climate change mitigation.”

Gilles Dufrasne from Carbon Market Watch said that “misleading advertisements by companies have real impacts on consumers and policymakers.”

“We’re fooled into believing that these companies are taking sufficient action, when the reality is far from it,” said Dufrasne. “Without more regulation, this will continue. We need governments and regulatory bodies to step up and put an end to this greenwashing trend.”

“Companies must face the reality of a changing planet,” he added. “What seemed acceptable a decade ago is no longer enough. Setting vague targets will get us nowhere without real action, and can be worse than doing nothing if it misleads the public.”

In a Monday op-ed, Penn State University climate scientist Michael Mann and Climate Communication director Susan Joy Hassol drew attention to the devastation wrought by corporations that have denied facts to delay necessary political-economic transformations—pointing specifically to a 40-year-long disinformation campaign bankrolled by fossil fuel interests.

Much of the damage caused by extreme weather disasters “could have been avoided had we acted decades ago when the scientific community—and indeed fossil fuel industry’s own scientists—recognized we had a problem,” the pair wrote in The Hill. “While the best time to act boldly to prevent climate catastrophe was decades ago, the second-best time is now.”

Given that the 25 firms analyzed account for roughly 5% of global greenhouse gas emissions, researchers stressed how important it is for them to quickly adopt and scale up best practices.

“If we are to meet this monumental challenge, we will need to use all the arrows in the quiver,” wrote Mann and Hassol. “We must incentivize the energy industry to move aggressively toward clean, renewable energy.”

They concluded, “There is no time left to waste, and failure is not an option.”

Why It’s So Hard to Regulate Algorithms

photo: adobe

Governments increasingly use algorithms to do everything from assign benefits to dole out punishment—but attempts to regulate them have been unsuccessful

In 2018, the New York City Council created a task force to study the city’s use of automated decision systems (ADS). The concern: Algorithms, not just in New York but around the country, were increasingly being employed by government agencies to do everything from informing criminal sentencing and detecting unemployment fraud to prioritizing child abuse cases and distributing health benefits. And lawmakers, let alone the people governed by the automated decisions, knew little about how the calculations were being made. 

Rare glimpses into how these algorithms were performing were not comforting: In several states, algorithms used to determine how much help residents will receive from home health aides have automatically cut benefits for thousands. Police departments across the country use the PredPol software to predict where future crimes will occur, but the program disproportionately sends police to Black and Hispanic neighborhoods. And in Michigan, an algorithm designed to detect fraudulent unemployment claims famously improperly flagged thousands of applicants, forcing residents who should have received assistance to lose their homes and file for bankruptcy.

New York City’s was the first legislation in the country aimed at shedding light on how government agencies use artificial intelligence to make decisions about people and policies.

At the time, the creation of the task force was heralded as a “watershed” moment that would usher in a new era of oversight. And indeed, in the four years since, a steady stream of reporting about the harms caused by high-stakes algorithms has prompted lawmakers across the country to introduce nearly 40 bills designed to study or regulate government agencies’ use of ADS, according to The Markup’s review of state legislation. 

The bills range from proposals to create study groups to requiring agencies to audit algorithms for bias before purchasing systems from vendors. But the dozens of reforms proposed have shared a common fate: They have largely either died immediately upon introduction or expired in committees after brief hearings, according to The Markup’s review.

In New York City, that initial working group took two years to make a set of broad, nonbinding recommendations for further research and oversight. One task force member described the endeavor as a “waste.” The group could not even agree on a definition for automated decision systems, and several of its members, at the time and since, have said they did not believe city agencies and officials had bought into the process.

Elsewhere, nearly all proposals to study or regulate algorithms have failed to pass. Bills to create study groups to examine the use of algorithms failed in Massachusetts, New York state, California, Hawaii, and Virginia. Bills requiring audits of algorithms or prohibiting algorithmic discrimination have died in California, Maryland, New Jersey, and Washington state. In several cases—California, New Jersey, Massachusetts, Michigan, and Vermont—ADS oversight or study bills remain pending in the legislature, but their prospects this session are slim, according to sponsors and advocates in those states.

The only state bill to pass so far, Vermont’s, created a task force whose recommendations—to form a permanent AI commission and adopt regulations—have so far been ignored, state representative Brian Cina told The Markup. 

The Markup interviewed lawmakers and lobbyists and reviewed written and oral testimony on dozens of ADS bills to examine why legislatures have failed to regulate these tools.

We found two key through lines: Lawmakers and the public lack fundamental access to information about what algorithms their agencies are using, how they’re designed, and how significantly they influence decisions. In many of the states The Markup examined, lawmakers and activists said state agencies had rebuffed their attempts to gather basic information, such as the names of tools being used.

Meanwhile, Big Tech and government contractors have successfully derailed legislation by arguing that proposals are too broad—in some cases claiming they would prevent public officials from using calculators and spreadsheets—and that requiring agencies to examine whether an ADS system is discriminatory would kill innovation and increase the price of government procurement.

Lawmakers Struggled to Figure Out What Algorithms Were Even in Use

One of the biggest challenges lawmakers have faced when seeking to regulate ADS tools is simply knowing what they are and what they do.

Following its task force’s landmark report, New York City conducted a subsequent survey of city agencies. It resulted in a list of only 16 automated decision systems across nine agencies, which members of the task force told The Markup they suspect is a severe underestimation.

“We don’t actually know where government entities or businesses use these systems, so it’s hard to make [regulations] more concrete,” said Julia Stoyanovich, a New York University computer science professor and task force member.

In 2018, Vermont became the first state to create its own ADS study group. At the conclusion of its work in 2020, the group reported that “there are examples of where state and local governments have used artificial intelligence applications, but in general the Task Force has not identified many of these applications.”

“Just because nothing popped up in a few weeks of testimony doesn’t mean that they don’t exist,” said Cina. “It’s not like we asked every single state agency to look at every single thing they use.”

In February, he introduced a bill that would have required the state to develop basic standards for agency use of ADS systems. It has sat in committee without a hearing since then.

In 2019, the Hawaii Senate passed a resolution requesting that the state convene a task force to study agency use of artificial intelligence systems, but the resolution was nonbinding and no task force convened, according to the Hawaii Legislative Reference Bureau. Legislators tried to pass a binding resolution again the next year, but it failed.

Legislators and advocacy groups who authored ADS bills in California, Maryland, Massachusetts, Michigan, New York, and Washington told The Markup that they have no clear understanding of the extent to which their state agencies use ADS tools. 

Advocacy groups like the Electronic Privacy Information Center (EPIC) that have attempted to survey government agencies regarding their use of ADS systems say they routinely receive incomplete information.

“The results we’re getting are straight-up non-responses or truly pulling teeth about every little thing,” said Ben Winters, who leads EPIC’s AI and Human Rights Project.

In Washington, after an ADS regulation bill failed in 2020, the legislature created a study group tasked with making recommendations for future legislation. The ACLU of Washington proposed that the group should survey state agencies to gather more information about the tools they were using, but the study group rejected the idea, according to public minutes from the group’s meetings.

“We thought it was a simple ask,” said Jennifer Lee, the technology and liberty project manager for the ACLU of Washington. “One of the barriers we kept getting when talking to lawmakers about regulating ADS is they didn’t have an understanding of how prevalent the issue was. They kept asking, ‘What kind of systems are being used across Washington state?’ ”

Lawmakers Say Corporate Influence a Hurdle

Washington’s most recent bill has stalled in committee, but an updated version will likely be reintroduced this year now that the study group has completed its final report, said state senator Bob Hasegawa, the bill’s sponsor

The legislation would have required any state agency seeking to implement an ADS system  to produce an algorithmic accountability report disclosing the name and purpose of the system, what data it would use, and whether the system had been independently tested for biases, among other requirements.

The bill would also have banned the use of ADS tools that are discriminatory and required that anyone affected by an algorithmic decision be notified and have a right to appeal that decision.

“The big obstacle is corporate influence in our governmental processes,” said Hasegawa. “Washington is a pretty high-tech state and so corporate high tech has a lot of influence in our systems here. That’s where most of the pushback has been coming from because the impacted communities are pretty much unanimous that this needs to be fixed.”

California’s bill, which is similar, is still pending in committee. It encourages, but does not require, vendors seeking to sell ADS tools to government agencies to submit an ADS impact report along with their bid, which would include similar disclosures to those required by Washington’s bill.

It would also require the state’s Department of Technology to post the impact reports for active systems on its website.

Led by the California Chamber of Commerce, 26 industry groups—from big tech representatives like the Internet Association and TechNet to organizations representing banks, insurance companies, and medical device makers—signed on to a letter opposing the bill.

“There are a lot of business interests here, and they have the ears of a lot of legislators,” said Vinhcent Le, legal counsel at the nonprofit Greenlining Institute, who helped author the bill.

Originally, the Greenlining Institute and other supporters sought to regulate ADS in the private sector as well as the public but quickly encountered pushback. 

“When we narrowed it to just government AI systems we thought it would make it easier,” Le said. “The argument [from industry] switched to ‘This is going to cost California taxpayers millions more.’ That cost angle, that innovation angle, that anti-business angle is something that legislators are concerned about.”

The California Chamber of Commerce declined an interview request for this story but provided a copy of the letter signed by dozens of industry groups opposing the bill. The letter states that the bill would “discourage participation in the state procurement process” because the bill encourages vendors to complete an impact assessment for their tools. The letter said the suggestion, which is not a requirement, was too burdensome. The chamber also argued that the bill’s definition of automated decision systems was too broad.

Industry lobbyists have repeatedly criticized legislation in recent years for overly broad definitions of automated decision systems despite the fact that the definitions mirror those used in internationally recognized AI ethics frameworks, regulations in Canada, and proposed regulations in the European Union.

During a committee hearing on Washington’s bill, James McMahan, policy director for the Washington Association of Sheriffs and Police Chiefs, told legislators he believed the bill would apply to “most if not all” of the state crime lab’s operations, including DNA, fingerprint, and firearm analysis.

Internet Association lobbyist Vicki Christophersen, testifying at the same hearing, suggested that the bill would prohibit the use of red light cameras. The Internet Association did not respond to an interview request.

“It’s a funny talking point,” Le said. “We actually had to put in language to say this doesn’t include a calculator or spreadsheet.”

Maryland’s bill, which died in committee, would also have required agencies to produce reports detailing the basic purpose and functions of ADS tools and would have prohibited the use of discriminatory systems.

“We’re not telling you you can’t do it [use ADS],” said Delegate Terri Hill, who sponsored the Maryland bill. “We’re just saying identify what your biases are up front and identify if they’re consistent with the state’s overarching goals and with this purpose.”

The Maryland Tech Council, an industry group representing small and large technology firms in the state, opposed the bill, arguing that the prohibitions against discrimination were premature and would hurt innovation in the state, according to written and oral testimony the group provided.

“The ability to adequately evaluate whether or not there is bias is an emerging area, and we would say that, on behalf of the tech council, putting in place this at this time is jumping ahead of where we are,” Pam Kasemeyer, the council’s lobbyist, said during a March committee hearing on the bill. “It almost stops the desire for companies to continue to try to develop and refine these out of fear that they’re going to be viewed as discriminatory.”

Limited Success in the Private Sector

There have been fewer attempts by state and local legislatures to regulate private companies’ use of ADS systems—such as those The Markup has exposed in the tenant screening and car insurance industries—but in recent years, those measures have been marginally more successful.

The New York City Council passed a bill that would require private companies to conduct bias audits of algorithmic hiring tools before using them. The tools are used by many employers to screen job candidates without the use of a human interviewer.

The legislation, which was enacted in January but does not take effect until 2023, has been panned by some of its early supporters, however, for being too weak.

Illinois also enacted a state law in 2019 that requires private employers to notify job candidates when they’re being evaluated by algorithmic hiring tools. And in 2021, the legislature amended the law to require employers who use such tools to report demographic data about job candidates to a state agency to be analyzed for evidence of biased decisions. 

This year the Colorado legislature also passed a law, which will take effect in 2023, that will create a framework for evaluating insurance underwriting algorithms and ban the use of discriminatory algorithms in the industry.

Astronaut Says View From Above Reveals ‘Absolutely Fragile’ Planet Earth

“It makes you want to cherish the Earth and protect it, the more you see it from space,” says a French astronaut calling for global cooperation to fight the climate crisis.

French astronaut Thomas Pesquet says the impacts of the climate emergency are clear from space—and worsening on his watch—and has expressed optimism that the kind of global cooperation that built the International Space Station can also be channeled to protect the planet he calls “an oasis in the cosmos.”

 “Through the portholes of the space station, we distinctly see Earth’s fragility.”

Pesquet, a European Space Agency astronaut, made to the remarks in an interview published Monday at CNN.

In November, Pesquet, completed a six-month mission aboard the International Space Station. It was his second tour at the ISS, following an earlier mission in 2016 and 2017.

From space, an astronaut has a unique view of “the fragility of planet Earth,” he told the outlet.

There’s simply “emptiness,” he said, “apart from this blue ball with everything we need to sustain human life, and life in general, which is absolutely fragile.”

“It makes you want to cherish the Earth and protect it,” he said, “the more you see it from space.”

According to Pesquet, the view from space also reveals the impacts of humanity’s destruction of nature such as river pollution. But the “most visual visible effect” of the climate crisis, he said, is the retreat of glaciers.

Compared to his earlier mission, Pesquet told CNN that on his 2021 tour he “could see a net increase in the frequency and the strength of extreme weather phenomena like hurricanes, like wildfires.”

He also likened the “peaceful cooperation between countries that were not always friends” in maintaining the space station, and suggested that transferring “that model to the way we deal with the environment on Earth” could lead to planetary protection. 

“If we can make a space station fly,” said Pesquet, “then we can save the planet.”

On Instagram, Pesquet has captured many remarkable images from the station, documenting both Earth’s beauty and the impacts of the climate crisis.

In October, Pesquet described viewing the climate crisis from space and the increasing prevalence of destructive events viewable from above. “Definitely, the hurricanes, seen from space, and the forest fires, I had never seen that before, especially on my previous mission.”

He conveyed his space view of the planetary crisis to French President Emmanuel Macron last year. “Through the portholes of the space station, we distinctly see Earth’s fragility,” he said. “We see the damaging effects of human activity, pollution of rivers and air pollution.”

He and the other astronauts on the 2021 mission also witnessed wildfires ravaging various regions including California, which was “covered in a cloud of smoke, we saw the flames with our naked eyes.”

Worsening impacts of the climate crisis from his tour five years earlier were clear, he said: “The weather phenomena are accelerating at an alarming rate.”

What is the best mask for COVID-19? A mechanical engineer explains the science after 2 years of testing masks in his lab

Photo: Adobe Stock

1. What changed in the CDC guidelines?

The CDC currently recommends that you “wear the most protective mask you can that fits well and that you will wear consistently.” The question, then, is what type of mask offers the best protection for you – by filtering the air you breathe in – and for those around you – by filtering the air you breathe out?

The CDC’s updated guidelines clearly lay out the hierarchy of protection: “Loosely woven cloth products provide the least protection, layered finely woven products offer more protection, well-fitting disposable surgical masks and KN95s offer even more protection, and well-fitting NIOSH-approved respirators (including N95s) offer the highest level of protection.”

From a performance standpoint, the N95 and KN95 masks are the best option. While supply chain limitations led to the CDC recommending people not wear N95s early in the pandemic, today they are easily obtainable and should be your first choice if you want the most protection.

The biggest change in the new guidelines has to do with cloth masks. Previous guidance from the CDC had said that some cloth masks could offer acceptable levels of protection. The new guidance still acknowledges that cloth masks can offer a small amount of protection but places them at the very bottom of the bunch.

2. What’s the difference between N95, surgical and cloth mask materials?

The effectiveness of a mask – how much protection a mask provides the wearer – is a combination of two major elements. First, there’s the ability of the material to capture particles. The second factor is the fraction of inhaled or exhaled air leaking out from around the mask – essentially, how well a mask fits. 

Most mask materials can be thought of as a tangled net of small fibers. Particles passing through a mask are stopped when they physically touch one of those fibers. N95s, KN95s and surgical masks are purpose-built to be effective at removing particles from air. Their fibers are typically made from melt-blown plastics, often polypropylene, and the strands are tiny – often less than four thousandths of an inch (10 micrometers) in diameter – or approximately one third the width of a human hair. These small fibers create a large amount of surface area within the mask for filtering and collecting particles. Although the specific construction and thickness of the materials used in N95, KN95 and surgical masks can vary, the filter media used are often quite similar.

These fibers are very tightly packed together so the gaps a particle must navigate through are very small. This results in a high probability that particles will end up touching and sticking to a fiber as they pass through a mask. These polypropylene materials also often have a static charge that can help attract and catch particles. 

Cloth masks are typically made of common woven materials such as cotton or polyester. The fibers are often large and less densely packed together, meaning particles can easily pass through the material. Adding more layers can help, but stacking layers has a diminishing return and the performance of a cloth mask, even with multiple layers, will still typically not match that of surgical mask or N95.

3. How much does fit matter for masks?

Fit is the other major component in how effective a mask is. Even if the materials used in a mask were perfect and it removed all particles from the air that passed through it, a mask can offer protection only if it doesn’t leak.

When you breathe in and out, air will always take the path of least resistance. If there are any gaps between a mask and someone’s face, a substantial fraction of every breath will seep out through those gaps and the mask will provide relatively little protection

Many cloth mask designs simply do not seal well. They are not stiff enough to push against the face, there are gaps where the mask doesn’t even come in contact with the face and it is not possible to cinch them tightly enough against the skin to form a decent seal.

But leaking is a concern for all masks. Although the materials used in surgical masks are quite effective, they often bunch and fold on the sides. These gaps provide an easy route for air and particles to leak out. Knotting and tucking surgical masks or wearing a cloth mask over a surgical mask can both significantly reduce leakage.

N95 masks aren’t immune to this problem either; if the nose clip isn’t securely pushed against your face, the mask is leaking. What makes N95s unique is that a specific requirement of the N95 certification process is making sure the masks can form a good seal.

4. What is different about omicron?

The mechanics of how masks function is likely no different for omicron than any other variant. The difference is that the omicron variant is more easily transmitted than previous variants. This high level of infectiousness makes wearing good-quality masks and wearing them correctly to limit the chances of catching or spreading the coronavirus that much more critical.

Unfortunately, the attributes that make for a good mask are the very things that make masks uncomfortable and not very stylish. If your cloth mask is comfy and light and feels like you are wearing nothing at all, it probably isn’t doing much to keep you and others safe from the coronavirus. The protection offered by a high-quality, well-fitting N95 or KN95 is the best. Surgical masks can be very effective at filtering out particles, but getting them to fit correctly can be tricky and makes the overall protection they will provide you questionable. If you have other options, cloth masks should be a last choice.

Sci-Fi Author Neal Stephenson tackles Global Warming Solutions in ‘Termination Shock’

There’s a Neal Stephenson Renaissance Going on Due to one Single Word

Metaverse. In case you’ve not heard of it, metaverse is the term that was coined by Stephenson in his dystopian novel “Snow Crash” to denote a virtual artificial world of corporate exploitation. In all its ironic glory the name, or a shortened version thereof, “Meta” was appropriated as a re-branding vehicle for that empire of corporate greed and exploitation… Facebook.

So then, what better backdrop for the new novel to launch, and with a potentially even more timely theme, could there be other than, namely, the looming destruction our planet faces due to climate change and excessive carbon emissions. Moreover, the lack of human cooperation needed to overcome greed and stupidity in order to resume ourselves.

If this particular perspective on a fictional, but perhaps, soon, all too real, set of circumstances, is not spot on, there is nevertheless a great need for these questions to be addressed.

After all it is ultimately the cooperation and consensus of the entire planet that will be necessary to find, and more importantly, implement a solution that will prevent armageddon.

Perhaps the newly intensified focus on the future – fantasies, but also concerns and disaster aversion planning, is just what is needed. Perhaps authors, artists, engineers and even an average citizen can begin today and find the thread of change in thinking, and ultimately, living that’s needed for all our survival.

From Bookshop.org:

One man – visionary billionaire restaurant chain magnate T. R. Schmidt, Ph.D. – has a Big Idea for reversing global warming, a master plan perhaps best described as “elemental.” But will it work? And just as important, what are the consequences for the planet and all of humanity should it be applied?

Ranging from the Texas heartland to the Dutch royal palace in the Hague, from the snow-capped peaks of the Himalayas to the sunbaked Chihuahuan Desert, Termination Shock brings together a disparate group of characters from different cultures and continents who grapple with the real-life repercussions of global warming. Ultimately, it asks the question: Might the cure be worse than the disease? 

Epic in scope while heartbreakingly human in perspective, Termination Shock sounds a clarion alarm, ponders potential solutions and dire risks, and wraps it all together in an exhilarating, witty, mind-expanding speculative adventure.

Drill, Baby, Drill: Capitalism’s Only Plan for Climate Is Collapse

Photo by Zbynek Burival on Unsplash

If we continue not acting against the real cause of the climate crisis—the capitalist mode of production and the capitalist worldview—they will take it as a social license to carry on with collapse.

This past week’s flurry of announcements over “ambitious action” by governments during the COP26 in Glasgow has been justly received with scepticism by climate justice activists and the general public (and enthusiastic support by the media in general). During this same period important revelations of the massive gap in terms of necessary emission cuts and country’s plans emerged, as the broader rejection of greenwashing became pervasive. The narrative of false solutions and green capitalism doesn’t work. Yesterday, the revelation that over 800 oil & gas wells are being planned for drilling still this year and in 2022, in the report “Drill, Baby, Drill“, makes it clear that the proceedings of COP26 are mostly propaganda, as the only real, mandatory and contractualized plan global capitalism has for the climate crisis is collapse.

The reason why the climate crisis is not being solved is because it will lead to the biggest shift in power in the history of humanity, it will lead to the biggest transfer of wealth and loss of profit in history.

The scenario is the most dire ever. Not only the concentration of CO2 in the atmosphere is at its highest for millions of years, temperatures keep pushing closer to 1.5ºC and emissions are rising once again after the Covid hiatus. The IPCC scientists have leaked the second draft of Group II’s report, which states that “estimates of committed CO2 emissions from current fossil energy infrastructure are 658 GtCO2 […] nearly the double the remaining carbon budget,” revealing that “others [scientists] stress that climate change is caused by industrial development and more specifically the character of social and economic development produced by the nature of the capitalist society, which they therefore view as ultimately unsustainable.” In a few months, we will understand the level of political and business editing in the final report that finally comes out.

Yet, current infrastructure is not enough for global capitalism. In the “Drill, Baby, Drill” report, made public by the Glasgow Agreement at the COP26 Coalition’s People Summit, a still bigger measure of incoherence appears. There are 816 new oil & gas wells being planned and drilled until the end of the year and in 2022. These are located in 76 countries all around the world, countries whose governments are currently sitting in the halls of the COP26 in Glasgow, to “negotiate” a solution for the climate crisis.

The host UK appears close to the top of desired new wells, with 36, mostly offshore, in the basins of Central Graben, Moray Firth, the North Sea and Shetland. It is very likely that while Boris Johnson was doing his James Bond gag on stage, at least some four wells were being drilled to add to British fossil fuel reserves, making him a sort of meta-Bond villain. The top of the ranking for most wells planned goes to Australia and Russia, with 80 wells each, closely followed by Mexico with 78. Australia, Russia, Mexico, Indonesia, USA, Norway, UK, Brazil and Myanmar plan to drill over 500 oil & gas wells between now and the end of 2022. The report points out that this is very likely an underestimation. The companies most involved in drilling these wells are the gallery of the usual suspects: ENI, Petronas, Shell, Equinor, Total, Pemex, BP, Pertamina, Chevron and ExxonMobil. There are at least 67 wells planned above the Arctic Polar Circle. Total and ExxonMobil are in a contest to drill the deepest well ever in the ocean (Total is going for 3628m deep in Angola, and ExxonMobil is going for 3800m deep in Brazil). Many of these companies are spending millions every year on propaganda for carbon neutrality and other false solutions, blocking real action and expanding their operations.

The report also includes a sample of wells drilled in 2021 so far, with China on top, followed by Turkey, Russia, Norway, Indonesia, Mexico, Pakistan, Australia and Egypt, the host for the next COP.

This shouldn’t come as a surprise to anyone. It is the way this system operates: just enough propaganda of “ambition” and technofixes to keep fossils flowing as ever, while the climate collapses. The information does provide us with a question: if the on climate change debate is framed by companies and governments around the terms of net-zero, carbon credits, carbon taxes and offsettings, rather than stopping emissions, when will it ever come to the real problem of the climate crisis? Well, never. And that is the purpose.

Governments and companies are actively engaged in not cutting emissions, but also in effectively increasing them. Each and every one of these wells is a public crime against Humanity and all species on this planet, advertised in advance. It is good that we know them, though, for it is better to know fossil capitalism’s plans to collapse us beforehand and in as much detail as possible. That is why the call on the report does not go out to governments and fossil companies to suddenly act after over three decades of expanding fossil use. The call goes out to the climate justice movement and civil society: spread this information far and wide, act on it, campaign on it, block, stop and detain all of these projects. Other millions of fossil and fossil-based projects compose the menu of collapse daily confirmed by governments and companies. They are the legally binding commitment for our collapse and need to be stopped.

The overwhelming agreement on the reason why the climate crisis is not being fixed is becoming as high as the overwhelming scientific agreement on the cause of the climate crisis. The reason why the climate crisis is not being solved is because it will lead to the biggest shift in power in the history of humanity, it will lead to the biggest transfer of wealth and loss of profit in history. That means very little to the majority of the human population, as we will be the beneficiaries of this shift, of this transfer, of this redistribution. If we solve this crisis, we will have the chance to heal our battered planet. That is why their plan means collapse: they refuse to abdicate an inch of their brutal privilege and power. If we continue not acting against the real cause of the climate crisis—the capitalist mode of production and the capitalist worldview—they will take it as a social license to carry on with collapse. Even without social license, their plan will always lead to collapse. It’s not circumstantial, it is the core of this system. We need to collapse them.
