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.

Offshore wind farms could help capture carbon from air and store it long-term – using energy that would otherwise go to waste

Video

Off the Massachusetts and New York coasts, developers are preparing to build the United States’ first federally approved utility-scale offshore wind farms – 74 turbines in all that could power 470,000 homes. More than a dozen other offshore wind projects are awaiting approval along the Eastern Seaboard.

By 2030, the Biden administration’s goal is to have 30 gigawatts of offshore wind energy flowing, enough to power more than 10 million homes.

Replacing fossil fuel-based energy with clean energy like wind power is essential to holding off the worsening effects of climate change. But that transition isn’t happening fast enough to stop global warming. Human activities have pumped so much carbon dioxide into the atmosphere that we will also have to remove carbon dioxide from the air and lock it away permanently.

Offshore wind farms are uniquely positioned to do both – and save money.

Most renewable energy lease areas off the Atlantic Coast are near the Mid-Atlantic states and Massachusetts. About 480,000 acres of the New York Bight is scheduled to be auctioned for wind farms in February 2022. BOEM

As a marine geophysicist, I have been exploring the potential for pairing wind turbines with technology that captures carbon dioxide directly from the air and stores it in natural reservoirs under the ocean. Built together, these technologies could reduce the energy costs of carbon capture and minimize the need for onshore pipelines, reducing impacts on the environment.

Capturing CO2 from the air

Several research groups and tech startups are testing direct air capture devices that can pull carbon dioxide directly from the atmosphere. The technology works, but the early projects so far are expensive and energy intensive.

The systems use filters or liquid solutions that capture CO2 from air blown across them. Once the filters are full, electricity and heat are needed to release the carbon dioxide and restart the capture cycle.

For the process to achieve net negative emissions, the energy source must be carbon-free.

The world’s largest active direct air capture plant operating today does this by using waste heat and renewable energy. The plant, in Iceland, then pumps its captured carbon dioxide into the underlying basalt rock, where the CO2 reacts with the basalt and calcifies, turning to solid mineral.

A similar process could be created with offshore wind turbines.

If direct air capture systems were built alongside offshore wind turbines, they would have an immediate source of clean energy from excess wind power and could pipe captured carbon dioxide directly to storage beneath the sea floor below, reducing the need for extensive pipeline systems.

Researchers are currently studying how these systems function under marine conditions. Direct air capture is only beginning to be deployed on land, and the technology likely would have to be modified for the harsh ocean environment. But planning should start now so wind power projects are positioned to take advantage of carbon storage sites and designed so the platforms, sub-sea infrastructure and cabled networks can be shared.

Using excess wind power when it isn’t needed

By nature, wind energy is intermittent. Demand for energy also varies. When the wind can produce more power than is needed, production is curtailed and electricity that could be used is lost.

That unused power could instead be used to remove carbon from the air and lock it away.

For example, New York State’s goal is to have 9 gigawatts of offshore wind power by 2035. Those 9 gigawatts would be expected to deliver 27.5 terawatt-hours of electricity per year.

Based on historical wind curtailment rates in the U.S., a surplus of 825 megawatt-hours of electrical energy per year may be expected as offshore wind farms expand to meet this goal. Assuming direct air capture’s efficiency continues to improve and reaches commercial targets, this surplus energy could be used to capture and store upwards of 0.5 million tons of CO2 per year.

That’s if the system only used surplus energy that would have gone to waste. If it used more wind power, its carbon capture and storage potential would increase.

Several Mid-Atlantic areas being leased for offshore wind farms also have potential for carbon storage beneath the seafloor. The capacity is measured in millions of metric tons of CO2 per square kilometer. The U.S. produces about 4.5 billion metric tons of CO2 from energy per year. U.S. Department of Energy and Battelle

The Intergovernmental Panel on Climate Change has projected that 100 to 1,000 gigatons of carbon dioxide will have to be removed from the atmosphere over the century to keep global warming under 1.5 degrees Celsius (2.7 Fahrenheit) compared to pre-industrial levels.

Researchers have estimated that sub-seafloor geological formations adjacent to the offshore wind developments planned on the U.S. East Coast have the capacity to store more than 500 gigatons of CO2. Basalt rocks are likely to exist in a string of buried basins across this area too, adding even more storage capacity and enabling CO2 to react with the basalt and solidify over time, though geotechnical surveys have not yet tested these deposits.

Planning both at once saves time and cost

New wind farms built with direct air capture could deliver renewable power to the grid and provide surplus power for carbon capture and storage, optimizing this massive investment for a direct climate benefit.

But it will require planning that starts well in advance of construction. Launching the marine geophysical surveys, environmental monitoring requirements and approval processes for both wind power and storage together can save time, avoid conflicts and improve environmental stewardship.

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.

#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

Click photo for more about 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.

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.

Electrifying homes to slow climate change: 4 essential reads

The latest reports from the Intergovernmental Panel on Climate Change show that to avoid massive losses and damage from global warming, nations must act quickly to reduce their greenhouse gas emissions. The good news is that experts believe it’s possible to cut global greenhouse gas emissions in half by 2030 through steps such as using energy more efficiently, slowing deforestation and speeding up the adoption of renewable energy.

Many of those strategies require new laws, regulations or funding to move forward at the speed and scale that’s needed. But one strategy that’s increasingly feasible for many consumers is powering their homes and devices with electricity from clean sources. These four articles from our archives explain why electrifying homes is an important climate strategy and how consumers can get started.

1. Why go electric?

As of 2020, home energy use accounted for about one-sixth of total U.S. energy consumption. Nearly half (47%) of this energy came from electricity, followed by natural gas (42%), oil (8%) and renewable energy (7%). By far the largest home energy use is for heating and air conditioning, followed by lighting, refrigerators and other appliances.

The most effective way to reduce greenhouse gas emissions from home energy consumption is to substitute electricity generated from low- and zero-carbon sources for oil and natural gas. And the power sector is rapidly moving that way: As a 2021 report from Lawrence Berkeley National Laboratory showed, power producers have reduced their carbon emissions by 50% from what energy experts predicted in 2005.

“This drop happened thanks to policy, market and technology drivers,” a team of Lawrence Berkeley lab analysts concluded. Wind and solar power have scaled up and cut their costs, so utilities are using more of them. Cheap natural gas has replaced generation from dirtier coal. And public policies have encouraged the use of energy-efficient technologies like LED light bulbs. These converging trends make electric power an increasingly climate-friendly energy choice.

2. Heat pumps for cold and hot days

Since heating and cooling use so much energy, switching from an oil- or gas-powered furnace to a heat pump can greatly reduce a home’s carbon footprint. As University of Dayton sustainability expert Robert Brecha explains, heat pumps work by moving heat in and out of buildings, not by burning fossil fuel.

“Extremely cold fluid circulates through coils of tubing in the heat pump’s outdoor unit,” Brecha writes. “That fluid absorbs energy in the form of heat from the surrounding air, which is warmer than the fluid. The fluid vaporizes and then circulates into a compressor. Compressing any gas heats it up, so this process generates heat. Then the vapor moves through coils of tubing in the indoor unit of the heat pump, heating the building.”

In summer, the process reverses: Heat pumps take energy from indoors and move that heat outdoors, just as a refrigerator removes heat from the chamber where it stores food and expels it into the air in the room where it sits.

Another option is a geothermal heat pump, which collects warmth from the earth and uses the same process as air source heat pumps to move it into buildings. These systems cost more, since installing them involves excavation to bury tubing below ground, but they also reduce electricity use.

3. Cooking without gas – or heat

For people who like to cook, the biggest sticking point of going electric is the prospect of using an electric stove. Many home chefs see gas flames as more responsive and precise than electric burners.

But magnetic induction, which cooks food by generating a magnetic field under the pot, eliminates the need to fire up a burner altogether.

“Instead of conventional burners, the cooking spots on induction cooktops are called hobs, and consist of wire coils embedded in the cooktop’s surface,” writes Binghamton University electrical engineering professor Kenneth McLeod.

Moving an electric charge through those wires creates a magnetic field, which in turn creates an electric field in the bottom of the cookware. “Because of resistance, the pan will heat up, even though the hob does not,” McLeod explains.

Induction cooktops warm up and cool down very quickly and offer highly accurate temperature control. They also are easy to clean, since they are made of glass, and safer than electric stoves since the hobs don’t stay hot when pans are lifted off them. Many utilities are offering rebates to cover the higher cost of induction cooktops.

4. Electric cars as backup power sources

Electrifying systems like home heating and cooking made residents even more vulnerable to power outages. Soon, however, a new backup system could become available: powering your home from your electric vehicle.

With interest in electric cars and light trucks rising in the U.S., auto makers are introducing many new EV models and designs. Some of these new rides will offer bidirectional charging – the ability to charge a car battery at home, then move that power back into the house, and eventually, into the grid.

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

Only a few models offer this capacity now, and it requires special equipment that can add several thousand dollars to the price of an EV. But Penn State energy expert Seth Blumsack sees value in this emerging technology.

“Enabling homeowners to use their vehicles as backup when the power goes down would reduce the social impacts of large-scale blackouts. It also would give utilities more time to restore service – especially when there is substantial damage to power poles and wires,” Blumsack explains. “Bidirectional charging is also an integral part of a broader vision for a next-generation electric grid in which millions of EVs are constantly taking power from the grid and giving it back – a key element of an electrified future.”

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.

Dozens Arrested as Scientists Worldwide Mobilize to Demand ‘Climate Revolution’

Photo Credit / Scientist Rebellion Twitter @ScientistRebel1

“If everyone could see what I see coming,” said one scientist, “society would switch into climate emergency mode and end fossil fuels in just a few years.”

More than 1,000 scientists across the globe chained themselves to the doors of oil-friendly banks, blocked bridges, and occupied the steps of government buildings on Wednesday to send an urgent message to the international community: The ecological crisis is accelerating, and only a “climate revolution” will be enough to avert catastrophe.

“World leaders are still expanding the fossil fuel industry as fast as they can, but this is insane.”

What organizers described as “the world’s largest-ever scientist-led civil disobedience campaign” kicked off just days after the Intergovernmental Panel on Climate Change (IPCC) released its latest report detailing the grim state of efforts to limit global warming to 1.5°C by century’s end, a target set by the Paris accord.

As one of the report’s authors put it during a press call earlier this week, “Unless there are immediate and deep emissions reductions across all sectors, 1.5°C is beyond reach.”

Warning that the IPCC report’s language was watered downat the behest of governments unwilling to rapidly phase out fossil fuels, scientists and their allies took that message further during their direct actions on Wednesday, operating under the slogan “1.5°C is dead, climate revolution now!”

“I’m taking action because I feel desperate,” said U.S. climate scientist Peter Kalmus, who along with several others locked himself to the front door of a JPMorgan Chase building in Los Angeles. A recent report found that the financial giant is the biggest private funder of oil and gas initiatives in the world.

“It’s the 11th hour in terms of Earth breakdown, and I feel terrified for my kids, and terrified for humanity,” Kalmus continued. “World leaders are still expanding the fossil fuel industry as fast as they can, but this is insane. The science clearly indicates that everything we hold dear is at risk, including even civilization itself and the wonderful, beautiful, cosmically precious life on this planet. I actually don’t get how any scientist who understands this could possibly stay on the sidelines at this point.”

The Los Angeles demonstration was accompanied by other protests across the U.S., the largest historical emitter of planet-warming carbon dioxide and home to some of the most powerful fossil fuel companies in the world.

In Washington, D.C., climate scientists chained themselves to the White House fence and were ultimately arrested as they demanded that U.S. President Joe Biden declare a “climate emergency,” a step that would unlock a range of tools needed to combat global warming.

“We have not made the changes necessary to limit warming to 1.5°C, rendering this goal effectively impossible,” said Dr. Rose Abramoff, one of the scientists arrested at the White House. “We need to both understand the consequences of our inaction as well as limit fossil fuel emissions as much and as quickly as possible.”

“I’m taking action to urge governments and society to stop ignoring the collective findings of decades of research,” Abramoff added. “Let’s make this crisis impossible to ignore.”

Similar acts of civil disobedience were held across the globe as scientists took to the streets to demand that governments ramp up their transitions to renewable energy as the climate crisis intensifies extreme weather, endangers critical ecosystems, and takes lives worldwide.

In Madrid, Spain, scientists splashed red paint on the walls and steps of the Congress of Deputies to decry lawmakers’ inaction in the face of the existential climate threat. More than 50 scientists were arrested during the demonstration, according to organizers.

Scientists also mobilized in Germany, blocking a bridge near the country’s parliament building.

In an op-ed published in The Guardian on Wednesday, Kalmus warned that “Earth breakdown is much worse than most people realize.”

“The science indicates that as fossil fuels continue to heat our planet, everything we love is at risk,” he wrote. “For me, one of the most horrific aspects of all this is the juxtaposition of present-day and near-future climate disasters with the ‘business as usual’ occurring all around me. It’s so surreal that I often find myself reviewing the science to make sure it’s really happening, a sort of scientific nightmare arm-pinch. Yes, it’s really happening.”

“If everyone could see what I see coming,” Kalmus added, “society would switch into climate emergency mode and end fossil fuels in just a few years.”

Rebellious Climate Scientists Have Message for Humanity: ‘Mobilize, Mobilize, Mobilize’

In face of the “escalating climate emergency,” the advocacy group Scientist Rebellion warns that IPCC summary to global policymakers remains “alarmingly reserved, docile, and conservative.”

Amid a weeklong global civil disobedience campaign to demand climate action commensurate with mounting evidence about the need for swift decarbonization, Scientist Rebellion is highlighting specific gaps between what experts say is necessary and what governments allowed to be published in a summary of the United Nations’ latest climate assessment.

“We need a billion climate activists…The time is now. We’ve waited far too long.”

The landmark report on mitigation by Working Group III of the Intergovernmental Panel on Climate Change (IPCC)—part of the U.N.’s sixth comprehensive climate assessment since 1992 and possibly the last to be published with enough time to avert the most catastrophic consequences of the planetary crisis—was compiled by 278 researchers from 65 countries.

The authors, who synthesized thousands of peer-reviewed studies published in the past several years, make clear over the course of nearly 3,000 pages that “without immediate and deep emissions reductions across all sectors, limiting global warming to 1.5°C is beyond reach.”

Meanwhile, a 64-page Summary for Policymakers (SPM) of the report—a key reference point for governments—required the approval of all 195 member states of the IPCC and was edited with their input.

Following a contentious weekend of negotiations in which wealthy governments attempted to weaken statements about green financing for low-income nations and fossil fuel-producing countries objected to unequivocal language about the need to quickly eliminate coal, oil, and gas extraction, the IPCC document was published several hours later than expected on Monday.

“Despite the escalating climate emergency and the total absence of emissions cuts, the framing of the final version of the SPM is still alarmingly reserved, docile, and conservative,” Scientist Rebellion, an international alliance of academics who are advocating for systemic political and economic changes in line with scientific findings, said Tuesday in a statement.

“The science has never been clearer: to have any chance of retaining a habitable planet, greenhouse gas emissions must be cut radically now,” the group continued. “Limiting warming to 1.5°C and responding to the climate emergency requires an immediate transformation across all sectors and strata of society, a mobilization of historic proportions: a climate revolution.”

“The IPCC [has] avoided naming the major culprits for 30 years, which is one reason for the absence of real emissions cuts,” the group added. “Facts detailing the complicity of the world’s richest countries in fueling the climate crisis have been watered down by the IPCC’s political review process.”

Scientist Rebellion proceeded to contrast the final version of the SPM—”the document that garners almost all attention”—to an early draft of a summary of the Working Group III report on mitigation that IPCC authors associated with the group leaked last August out of concern that their conclusions would be diluted by policymakers.

Peter Kalmus, a Los Angeles-based climate scientist and author who is participating in this week’s direct actions, told Common Dreams that the shortcomings of governments and policymakers have driven him to act.

Kalmus said he was willing to engage in civil disobedience and risk arrest this week, “because I’ve tried everything else I can think of over the past decade and nothing has worked. I see humanity heading directly toward climate disaster.”

With humanity “currently on track to lose everything we love,” he said, the scientific community must intensify its efforts.

“If we don’t rapidly end the fossil fuel industry and begin acting like Earth breakdown is an emergency, we risk civilizational collapse and potentially the death of billions, not to mention the loss of major critical ecosystems around the world,” said Kalmus. “This is so much bigger than me. Expect climate scientists to be taking such actions repeatedly in the future and in large numbers.”

On Wednesday, direct actions by scientists took place in Berlin, Germany; The Hague, Netherlands; Bogata, Colombia, and other cities.

https://twitter.com/wirereporter/status/1511705115517935617?s=20&t=LlCjWCRAmgFIMD1RfOn4uw

In its Tuesday assessment, Scientist Rebellion documented how the political review process weakened or eliminated language about carbon inequality and the need for far-reaching socio-economic transformation to slash greenhouse gas (GHG) pollution in the final SPM:

Example 1: Section B6 of the report originally stated that “institutional inertia and a social bias towards the status quo are leading to a risk of locking in future GHG emissions that may be costly or difficult to abate.” This has been replaced with “global GHG emissions in 2030 associated with the implementation of nationally determined contributions… would make it likely that warming will exceed 1.5°C during the 21st century.” The final version also no longer mentions that “vested interests” and a focus on an “incremental rather than a systemic approach” are limiting factors to ambitious transformation.

Example 2: The leaked SPM stated that “within countries, inequalities increased for both income and GHG emissions between 1970 and 2016, with the top 1% accounting for 27% of income growth,” and that “top emitters dominate emissions in key sectors, for example the top 1% account for 50% of GHG emissions from aviation.” Neither statement appears in the final version.

“While the SPM—being approved line-by-line by all governments—is reserved, docile, and conservative, the situation is clear,” said Scientist Rebellion.

The group went on to quote U.N. Secretary-General António Guterres, who said Monday that “we are on a fast track to climate disaster.”

As Common Dreams reported Monday, more than 1,000 scientists in at least 25 countries on every continent in the world are expected to participate in strikes, occupations, and other actions this week to highlight “the urgency and injustice of the climate and ecological crisis,” and several demonstrations are already underway. 

Guterres, for his part, said Monday that “climate activists are sometimes depicted as dangerous radicals, but the truly dangerous radicals are the countries that are increasing the production of fossil fuels.”

For his part, Kalmus acknowledged it was going to take much more than a series of direct actions by scientists to turn the tide against inaction.

“We need a billion climate activists,” Kalmus said. “I encourage everyone to consider where we’re heading as a species, and to engage in civil disobedience and other actions. The time is now. We’ve waited far too long.”

“Mobilize, mobilize, mobilize,” he said, “before we lose everything.”

On top of drastic emissions cuts, IPCC finds large-scale CO₂ removal from air will be “essential” to meeting targets

A Climate Change Concept Image

Sam Wenger, University of Sydney and Deanna D’Alessandro, University of Sydney

Large-scale deployment of carbon dioxide removal (CDR) methods is now “unavoidable” if the world is to reach net-zero greenhouse gas emissions, according to this week’s report by the Intergovernmental Panel on Climate Change (IPCC).

The report, released on Monday, finds that in addition to rapid and deep reductions in greenhouse emissions, CO₂ removal is “an essential element of scenarios that limit warming to 1.5℃ or likely below 2℃ by 2100”.

CDR refers to a suite of activities that lower the concentration of CO₂ in the atmosphere. This is done by removing CO₂ molecules and storing the carbon in plants, trees, soil, geological reservoirs, ocean reservoirs or products derived from CO₂.

As the IPCC notes, each mechanism is complex, and has advantages and pitfalls. Much work is needed to ensure CDR projects are rolled out responsibly.

How does CDR work?

CDR is distinct from “carbon capture”, which involves catching CO₂ at the source, such as a coal-fired power plant or steel mill, before it reaches the atmosphere.

There are several ways to remove CO₂ from the air. They include:

  • terrestrial solutions, such as planting trees and adopting regenerative soil practices, such as low or no-till agriculture and cover cropping, which limit soil disturbances that can oxidise soil carbon and release CO₂.
  • geochemical approaches that store CO₂ as a solid mineral carbonate in rocks. In a process known as “enhanced mineral weathering”, rocks such as limestone and olivine can be finely ground to increase their surface area and enhance a naturally occurring process whereby minerals rich in calcium and magnesium react with CO₂ to form a stable mineral carbonate.
  • chemical solutions such as direct air capture that use engineered filters to remove CO₂ molecules from air. The captured CO₂ can then be injected deep underground into saline aquifers and basaltic rock formations for durable sequestration.
  • ocean-based solutions, such as enhanced alkalinity. This involves directly adding alkaline materials to the environment, or electrochemically processing seawater. But these methods need to be further researched before being deployed.

Where is it being used right now?

To date, US-based company Charm Industrial has delivered 5,000 tonnes of CDR, which is the the largest volume thus far. This is equivalent to the emissions produced by about 1,000 cars in a year.

There are also several plans for larger-scale direct air capture facilities. In September, 2021, Climeworks opened a facility in Iceland with a 4,000 tonne per annum capacity for CO₂ removal. And in the US, the Biden Administration has allocated US$3.5 billion to build four separate direct air capture hubs, each with the capacity to remove at least one million tonnes of CO₂ per year.

However, a previous IPCC report estimated that to limit global warming to 1.5℃, between 100 billion and one trillion tonnes of CO₂ must be removed from the atmosphere this century. So while these projects represent a massive scale-up, they are still a drop in the ocean compared with what is required.

In Australia, Southern Green Gas and Corporate Carbon are developing one of the country’s first direct air capture projects. This is being done in conjunction with University of Sydney researchers, ourselves included.

In this system, fans push atmospheric air over finely tuned filters made from molecular adsorbents, which can remove CO₂ molecules from the air. The captured CO₂ can then be injected deep underground, where it can remain for thousands of years.

Opportunities

It is important to stress CDR is not a replacement for emissions reductions. However, it can supplement these efforts. The IPCC has outlined three ways this might be done.

In the short term, CDR could help reduce net CO₂ emissions. This is crucial if we are to limit warming below critical temperature thresholds.

In the medium term, it could help balance out emissions from sectors such as agriculture, aviation, shipping and industrial manufacturing, where straightforward zero-emission alternatives don’t yet exist.

In the long term, CDR could potentially remove large amounts of historical emissions, stabilising atmospheric CO₂ and eventually bringing it back down to pre-industrial levels.

The IPCC’s latest report has estimated the technological readiness levels, costs, scale-up potential, risk and impacts, co-benefits and trade-offs for 12 different forms of CDR. This provides an updated perspective on several forms of CDR that were lesser explored in previous reports.

It estimates each tonne of CO₂ retrieved through direct air capture will cost US$84–386, and that there is the feasible potential to remove between 5 billion and 40 billion tonnes annually.

Concerns and challenges

Each CDR method is complex and unique, and no solution is perfect. As deployment grows, a number of concerns must be addressed.

First, the IPCC notes scaling up CDR must not detract from efforts to dramatically reduce emissions. They write that “CDR cannot serve as a substitute for deep emissions reductions but can fulfil multiple complementary roles”.

If not done properly, CDR projects could potentially compete with agriculture for land or introduce non-native plants and trees. As the IPCC notes, care must be taken to ensure the technology does not negatively affect biodiversity, land-use or food security.

The IPCC also notes some CDR methods are energy-intensive, or could consume renewable energy needed to decarbonise other activities.

It expressed concern CDR might also exacerbate water scarcity and make Earth reflect less sunlight, such as in cases of large-scale reforestation.

Given the portfolio of required solutions, each form of CDR might work best in different locations. So being thoughtful about placement can ensure crops and trees are planted where they won’t dramatically alter the Earth’s reflectivity, or use too much water.

Direct air capture systems can be placed in remote locations that have easy access to off-grid renewable energy, and where they won’t compete with agriculture or forests.

Finally, deploying long-duration CDR solutions can be quite expensive – far more so than short-duration solutions such as planting trees and altering soil. This has hampered CDR’s commercial viability thus far.

But costs are likely to decline, as they have for many other technologies including solar, wind and lithium-ion batteries. The trajectory at which CDR costs decline will vary between the technologies.

Future efforts

Looking forward, the IPCC recommends accelerated research, development and demonstration, and targeted incentives to increase the scale of CDR projects. It also emphasises the need for improved measurement, reporting and verification methods for carbon storage.

More work is needed to ensure CDR projects are deployed responsibly. CDR deployment must involve communities, policymakers, scientists and entrepreneurs to ensure it’s done in an environmentally, ethically and socially responsible way.

New Analysis Details ‘Master Class in War Profiteering’ by US Oil Giants

“Oil and gas companies are feeding off humanitarian disaster and consumer suffering in order to reward Wall Street,” said Lukas Ross at Friends of the Earth.

An analysis released Tuesday by a trio of groups highlights how Big Oil has cashed in on various crises over the past year—including the Covid-19 pandemic, Russia’s war on Ukraine, and the global climate emergency—while enriching wealthy shareholders.

“Big Oil is living the second half of their unspoken mantra ‘socialize losses, privatize gains.'”

The new report from BailoutWatch, Friends of the Earth, and Public Citizen explains that there are two main tactics that fossil fuel giants use to benefit investors: “First, they repurchase shares of their own stock and retire them, reducing the number of shares outstanding and driving up the value of each share remaining in investors’ hands.”

“Second, they increase dividends, the quarterly payments investors receive for owning shares,” the report continues. “Oil and gas dividends, historically bigger than other sectors’, have spiked in recent months, outstripping every other industry group.”

“Amid high gas prices and war in recent months, oil and gas companies have kicked both tactics into overdrive,” the groups found, based on reviewing public statements and securities filings from the 20 largest U.S.-headquartered fossil fuel corporations.

During the first two months of 2022, “seven companies’ boards authorized their corporate treasuries to buy back and retire $24.35 billion in stock—a 15% increase over all of the buybacks authorized in 2021,” the report states. “Six of those decisions came in February 2022, after Russian warmongering lifted stock prices. The total since the start of 2021 is $45.6 billion.”

The analysis also reveals that in January and February, 11 companies raised their dividends—”often extravagantly”—and notes that “nine were increases of more than 15% and four were increases of more than 40%.”

“Six companies have begun paying additional dividends on top of their routine quarterly payments, including by implementing new variable dividends based on company earnings—a way of directing windfall profits immediately into private hands without any possibility of investment, employee benefits, or other uses,” the document points out.

“So far in 2022, these companies have started paying out an initial $3 billion in special windfall dividends,” the report adds. “Four of these companies—Pioneer, Chesapeake, Conoco, and Coterra—announced variable dividends beginning August 2021, as prices began to rise.”

Chris Kuveke of BailoutWatch said in a statement that “Big Oil is living the second half of their unspoken mantra ‘socialize losses, privatize gains.'”

“Two years after winning multi-billion dollar bailouts from the Trump administration, these newly flush companies are pocketing billions from an international crisis, and they don’t care how it affects regular Americans,” Kuveke added.

As Public Citizen researcher Alan Zibel put it: “Big Oil executives are reaping windfall profits while accelerating the climate crisis and sticking consumers with the bill.”

Zibel also acknowledged efforts to blame President Joe Biden for rising prices, rather than industry profiteering.

“The oil industry and their allies on Capitol Hill falsely claim that the Biden administration’s acceptance of mainstream climate science is stifling investment in the domestic oil industry,” he said. “But the industry’s actions show that they are intently focused on funneling cash to their shareholders rather than lowering prices for consumers.”

According to Lukas Ross, climate and energy program manager at Friends of the Earth: “This is a master class in war profiteering. Oil and gas companies are feeding off humanitarian disaster and consumer suffering in order to reward Wall Street.”

“Oil companies drove us into a climate crisis and are now price gouging us to extinction,” he warned. “Congress and President Biden must take action by passing a windfall profits tax to rein in Big Oil’s cash grab.”

The new analysis follows the introduction of multiple bills targeting Big Oil’s windfall profits, including a proposal spearheaded by Senate Budget Committee Chair Bernie Sanders (I-Vt.) designed to crack down on such behavior in all sectors, not just the fossil fuel industry.

Sanders on Tuesday morning held a hearing to call out how corporate greed and profiteering are fueling inflation. During his opening remarks, the chair took aim at Big Oil specifically while listing some examples.

“Yesterday, at a time when gasoline in America is now at a near-record high at $4.17 a gallon, guess what?” Sanders said. “ExxonMobil reported that its profit from pumping oil and gas alone in the first quarter will likely hit a record high of $9.3 billion.”

“Meanwhile,” he added, “Big Oil CEOs are on track to spend $88 billion this year not to decrease supply constraints, not to address the climate crisis, but to buy back their own stock and hand out dividends to enrich their wealthy shareholders.”

The House Energy and Commerce Committee’s Subcommittee on Oversight and Investigations plans to hold a hearing Wednesday titled “Gouged at the Gas Station: Big Oil and America’s Pain at the Pump.” Top executives from BP America, Chevron, Devon Energy, ExxonMobil, Pioneer Natural Resources, and Shell USA are set to appear before the panel.

Revolutionary changes in transportation, from electric vehicles to ride sharing, could slow global warming – if they’re done right, IPCC says

Electric vehicle sales are growing quickly. Michael Fousert/Unsplash

Alan Jenn, University of California, Davis

Around the world, revolutionary changes are under way in transportation. More electric vehicles are on the road, people are taking advantage of sharing mobility services such as Uber and Lyft, and the rise in telework during the COVID-19 pandemic has shifted the way people think about commuting.

Transportation is a growing source of the global greenhouse gas emissions that are driving climate change, accounting for 23% of energy-related carbon dioxide emissions worldwide in 2019 and 29% of all greenhouse gas emissions in the U.S.

The systemic changes under way in the transportation sector could begin lowering that emissions footprint. But will they reduce emissions enough?

In a new report from the Intergovernmental Panel on Climate Change released April 4, 2022, scientists examined the latest research on efforts to mitigate climate change. The report concludes that falling costs for renewable energy and electric vehicle batteries, in addition to policy changes, have slowed the growth of climate change in the past decade, but that deep, immediate cuts are necessary. Emissions will have to peak by 2025 to keep global warming under 1.5 degrees Celsius (2.7 F), a Paris Agreement goal, the report says.

Costs are falling for key forms of renewable energy and EV batteries, and adoption of these technologies is rising. IPCC Sixth Assessment Report

The transportation chapter, which I contributed to, homed in on transportation transformations – some just starting and others expanding – that in the most aggressive scenarios could reduce global greenhouse gas emissions from transportation by 80% to 90% of current levels by 2050. That sort of drastic reduction would require a major, rapid rethinking of how people get around globally.

The future of EVs

All-electric vehicles have grown dramatically since the Tesla Roadster and Nissan Leaf arrived on the market a little over a decade ago, following the popularity of hybrids.

In 2021 alone, the sales of electric passenger vehicles, including plug-in hybrids, doubled worldwide to 6.6 million, about 9% of all car sales that year.

Strong regulatory policies have encouraged the production of electric vehicles, including California’s Zero Emission Vehicle regulation, which requires automakers to produce a certain number of zero-emission vehicles based on their total vehicles sold in California; the European Union’s CO2 emissions standards for new vehicles; and China’s New Energy Vehicle policy, all of which have helped push EV adoption to where we are today.

Pickups, Vans and SUVs, which typically have much lower gas mileage than cars, make up the majority of new car sales in the U.S. Electric versions could be game-changers for emissions.

Beyond passenger vehicles, many micro-mobility options – such as autorickshaws, scooters and bikes – as well as buses, have been electrified. As the cost of lithium-ion batteries decreases, these transportation options will become increasingly affordable and further boost sales of battery-powered vehicles that traditionally have run on fossil fuels.

An important aspect to remember about electrifying the transportation system is that its ability to cut greenhouse gas emissions ultimately depends on how clean the electricity grid is. China, for example, is aiming for 20% of its vehicles to be electric by 2025, but its electric grid is still heavily reliant on coal.

With the global trends toward more renewable generation, these vehicles will be connected with fewer carbon emissions over time. There are also many developing and potentially promising co-benefits of electromobility when coupled with the power system. The batteries within electric vehicles have the potential to act as storage devices for the grid, which can assist in stabilizing the intermittency of renewable resources in the power sector, among many other benefits.

Other areas of transportation are more challenging to electrify. Larger and heavier vehicles generally aren’t as conducive to electrification because the size and weight of the batteries needed rapidly becomes untenable.

For some heavy-duty trucks, ships and airplanes, alternative fuels such as hydrogen, advanced biofuels and synthetic fuels are being explored as replacements for fossil fuels. Most aren’t economically feasible yet, and substantial advances in the technology are still needed to ensure they are either low- or zero-carbon.

Other ways to cut emissions from transportation

While new fuel and vehicle technologies are often highlighted as decarbonization solutions, behavioral and other systemic changes will also be needed to meet to cut greenhouse gas emissions dramatically from this sector. We are already in the midst of these changes.

Telecommuting: During the COVID-19 pandemic, the explosion of teleworking and video conferencing reduced travel, and, with it, emissions associated with commuting. While some of that will rebound, telework is likely to continue for many sectors of the economy.

Shared mobility: Some shared mobility options, like bike and scooter sharing programs, can get more people out of vehicles entirely.

Car-sharing and on-demand services such as Uber and Lyft also have the potential to reduce emissions if they use high-efficiency or zero-emission vehicles, or if their services lean more toward car pooling, with each driver picking up multiple passengers. Unfortunately, there is substantial uncertainty about the impact of these services. They might also increase vehicle use and, with it, greenhouse gas emissions.

New policies such as the California Clean Miles Standard are helping to push companies like Uber and Lyft to use cleaner vehicles and increase their passenger loads, though it remains to be seen whether other regions will adopt similar policies.

Public transit-friendly cities: Another systemic change involves urban planning and design. Transportation in urban areas is responsible for approximately 8% of global carbon dioxide emissions.

Efficient city planning and land use can reduce travel demand and shift transportation modes, from cars to public transit, through strategies that avoid urban sprawl and disincentivize personal cars. These improvements not only decrease greenhouse gas emissions, but can decrease congestion, air pollution and noise, while improving the safety of transportation systems.

https://datawrapper.dwcdn.net/OcmIT/5/

How do these advances translate to lower emissions?

Much of the uncertainty in how much technological change and other systemic shifts in transportation affects global warming is related to the speed of transition.

The new IPCC report includes several potential scenarios for how much improvements in transportation will be able to cut emissions. On average, the scenarios indicate that the carbon intensity of the transportation sector would need to decrease by about 50% by 2050 and as much as 91% by 2100 when combined with a cleaner electricity grid to stay within the 1.5-degree Celsius (2.7 Fahrenheit) target for global warming.

These decreases would require a complete reversal of current trends of increasing emissions in the transportation sector, but the recent advances in transportation provide many opportunities to meet this challenge.

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

To most people, a solar farm or a geothermal plant is simply a power producer. Scientists and engineers see 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.

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. https://www.youtube.com/embed/w4XLBOnzE6Q?wmode=transparent&start=0 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.

As Consumers Pay, Oil CEO’s Refuse to Testify to Congress About Soaring Prices

“While Americans struggle with high gas prices, these companies are doing victory laps, showering their already wealthy executives and shareholders with billions in stock buybacks and bonus compensation,” said one watchdog group. “They should be ashamed.”

As people across the United States face record-high gas prices—compounded by rising grocery bills and prices for other essentials—executives at three major oil companies are refusing to testify before Congress about what their firms could do to lessen the burden on U.S. households, leaving Democratic lawmakers and consumer advocates to condemn the companies for profiting amid lower and middle-class people’s financial pain.

Rep. Raúl M. Grijalva (D-Ariz.), who chairs the House Natural Resources Committee, had invited the CEOs of EOG Resources Inc., Devon Energy Corp. and Occidental Petroleum Corp. to testify next week, only to be rebuffedTuesday by the executives, who have personally profited off gas prices which averaged $4.24 per gallon on Monday.

“I invited these companies to come before the committee and make their case, but apparently they don’t think it’s worth defending,” Grijalva said in a statement Tuesday. “Their silence tells us all we need to know—that cries for more drilling and looser regulations are nothing more than another age-old attempt to line their own pockets.

Since oil and gas prices began rising earlier this year as traveling and commuting increased, and went up further following Russia’s invasion of Ukraine in February, the fossil fuel industry has claimed the Biden administration should release more permits for drilling on public lands and accelerate approval of permits for building energy infrastructure, with the American Petroleum Institute pushing for what Grijalva called “a domestic drilling free-for-all” earlier this month.

Lawmakers including Grijalva have argued that the companies could easily stabilize gas prices immediately, considering the billions of dollars in profits EOG Resources, Devon Energy, and Occidental Petroleum raked in last year.

Instead, watchdog group Accountable.US said Tuesday, Occidental Petroleum planned to use $3 billion for stock buybacks in 2022, while Devon Energy gave nearly $2 billion in share buybacks and dividends to shareholders last year. EOG Resources gave CEO William R. Thomas a $150,000 raise in 2021, making his total compensation $9.8 million.

“We want to work with them to reduce gas prices, but it seems as though they’re too busy taking in record profits while refusing to pass savings on to consumers,” said Rep. Mike Levin (D-Calif.), a member of the Natural Resources Committee.

Rep. Mark Pocan (D-Wis.) sarcastically expressed empathy for the “spineless” executives who refused to testify before Grijalva’s committee.

“It is hardly surprising that EOG Resources, Devon Energy, and Occidental Petroleum are dodging accountability by refusing to testify in Congress,” said Kyle Herrig, president of watchdog group Accountable.US. “While Americans struggle with high gas prices, these companies are doing victory laps, showering their already wealthy executives and shareholders with billions in stock buybacks and bonus compensation. They should be ashamed.”

Grijalva noted that while the industry has used the Russian invasion of Ukraine to call for even more freedom to drill for oil and gas, fossil fuel companies hold leases on 26 million acres of land.

“These same companies already have over 9,000 approved permits they can use whenever they want,” Grijalva told Public News Service on Tuesday. “And the very companies with thousands of acres of existing leases and hundreds of unused permits are the same ones shouting that they need more land for drilling.”

According to Accountable.US, the three companies refusing to speak to Grijalva’s committee “are among the top leaseholders of public lands oil and gas leases with 4,114 leases covering nearly 1.5 million acres.”

Companies including BP, Chevron, Exxon Mobil, and Shell have also been invited to testify at upcoming hearings on their business practices and impacts on consumers. In February, board members from the four companies refused to testify about the firms’ climate pledges.

Senate Majority Leader Chuck Schumer (D-N.Y.) noted last week that oil prices dropped in recent days, but no savings were passed onto consumers.

“The bewildering incongruity between falling oil prices and rising gas prices smacks of price gouging and is deeply damaging to working Americans,” Schumer said last week. “The Senate is going to get answers.”

‘Unthinkable’: Scientists Shocked as Polar Temperatures Soar 50 to 90 Degrees Above Normal

Above: Photo Collage / Lynxotic / Adobe Stock

“With everything going on in the world right now, the dual polar climate disasters of 2022 should be the top story”

Scientists expressed shock and alarm this weekend amid extreme high temperatures near both of the Earth’s poles—the latest signs of the accelerating planetary climate emergency.

“This event is completely unprecedented and upended our expectations about the Antarctic climate system.”

Temperatures in parts of Antarctica were 50°F-90°F above normal in recent days, while earlier this week the mercury soared to over 50°F higher than average—close to the freezing mark—in areas of the Arctic.

Stefano Di Battista, an Antarctic climatologist, tweeted that such record-shattering heat near the South Pole was“unthinkable” and “impossible.”

“Antarctic climatology has been rewritten,” di Battista wrote.

The joint French-Italian Concordia research station in eastern Antarctica recorded an all-time high of 10°F on Friday. In contrast, high temperatures at the station this time in March average below -50°F.

Jonathan Wille, a researcher studying polar meteorology at Université Grenoble Alpes in France, told The Washington Post that “this event is completely unprecedented and upended our expectations about the Antarctic climate system.”

“This is when temperatures should be rapidly falling since the summer solstice in December,” Wille tweeted. “This is a Pacific Northwest 2021 heatwave kind of event,” he added, referring to the record-breaking event in which parts of Canada topped 120°F for the first time in recorded history. “Never supposed to happen.”

Walt Meier, a senior research scientist at the National Snow and Ice Data Center in Boulder, Colorado, toldUSA Today that “you don’t see the North and the South [poles] both melting at the same time” because “they are opposite seasons.”

“It’s definitely an unusual occurrence,” he added.

As Common Dreams has reported, the Arctic has been warming three times faster than the world as a whole, accelerating polar ice melt, ocean warming, and other manifestations of the climate emergency.

“Looking back over the last few decades, we can clearly see a trend in warming, particularly in the ‘cold season’ in the Arctic,” Ruth Mottram, a climate scientist with the Danish Meteorological Institute, told the Post. “It’s not surprising that warm air is busting through into the Arctic this year. In general, we expect to see more and more of these events in the future.”

‘Addiction to Fossil Fuels Is Mutually Assured Destruction,’ Warns UN Chief

Above: Photo Collage / Lynxotic / Adobe Stock

“Instead of hitting the brakes on the decarbonization of the global economy” amid Russia’s war on Ukraine, “now is the time to put the pedal to the metal towards a renewable energy future,” said United Nations Secretary-General António Guterres.

“The 1.5-degree goal is on life support. It is in intensive care.”

So said United Nations Secretary-General António Guterres on Monday, as he stressed that a swift and just transition to clean energy is necessary to meet the Paris agreement’s objective of limiting global temperature rise to 1.5°C above preindustrial levels—and warned against using Russia’s deadly assault on Ukraine as an excuse to ramp up fossil fuel production worldwide.

“We are sleepwalking to climate catastrophe.”

“The science is clear. So is the math,” the U.N. leader said during a speech delivered at a Sustainability Summit hosted by The Economist. “Keeping 1.5 alive requires a 45% reduction in global emissions by 2030 and carbon neutrality by mid-century.” And yet, “according to present national commitments, global emissions are set to increase by almost 14% in the 2020s.”

“We are sleepwalking to climate catastrophe,” Guterres continued. “Our planet has already warmed by as much as 1.2 degrees—and we see the devastating consequences everywhere. In 2020, climate disasters forced 30 million people to flee their homes—three times more than those displaced by war and violence.”

Just this past weekend, scientists conveyed shock and alarm in response to reports that temperatures at both of Earth’s poles reached more than 50°F above average last week. Peer-reviewed research published on Friday foundthat increasingly frequent and intense wildfires around the globe are exacerbating Arctic warming, which is worsening the conditions that make future blazes more likely.

“Two weeks ago,” said Guterres, citing part two of the U.N.’s landmark climate assessment, “the IPCC confirmed that half of humanity is already living in the danger zone. Small island nations, least developed countries, and poor and vulnerable people everywhere are one climate shock away from doomsday. In our globally connected world, no country and no corporation can insulate itself from these levels of chaos.”

“If we continue with more of the same, we can kiss 1.5 goodbye,” he added. “Even 2 degrees may be out of reach. And that would be catastrophe.”

Making matters worse, said Guterres, “the fallout from Russia’s war in Ukraine risks upending global food and energy markets—with major implications for the global climate agenda.”

“As major economies pursue an ‘all-of-the-above’ strategy to replace Russian fossil fuels, short-term measures might create long-term fossil fuel dependence.”

The United States, United Kingdom, and European Union have moved to restrict imports of Russian fossil fuels in response to Moscow’s military offensive. Although progressives have emphasized that the ongoing invasion should lead to an intensification of efforts to move awayfrom dirty energy, profit-hungry proponents of oil, gas, and coal have seized on surging prices to push for boosting extraction and exports.

Guterres warned that “as major economies pursue an ‘all-of-the-above’ strategy to replace Russian fossil fuels, short-term measures might create long-term fossil fuel dependence and close the window to 1.5 degrees.”

Think like a Monk

“Countries could become so consumed by the immediate fossil fuel supply gap that they neglect or knee-cap policies to cut fossil fuel use,” he said. “This is madness. Addiction to fossil fuels is mutually assured destruction.”

“As current events make all too clear, our continued reliance on fossil fuels puts the global economy and energy security at the mercy of geopolitical shocks and crises,” added Guterres. “We need to fix the broken global energy mix.”

Noting that “the timeline to cut emissions by 45% is extremely tight,” the U.N. leader stressed that “instead of hitting the brakes on the decarbonization of the global economy, now is the time to put the pedal to the metal towards a renewable energy future.”

His remarks came just hours before the Intergovernmental Panel on Climate Change (IPCC) kicked off a two-week meeting to validate part three of its report, which focuses on the need to drastically slash carbon pollution to avoid the most disastrous outcomes.

Guterres argued that cooperation between the developed and emerging economies of the G20—responsible for 80% of global emissions—is essential to addressing the planetary emergency.

“Accelerating the phase-out of coal and all fossil fuels and implementing a rapid, just, and sustainable energy transition,” he said, is “the only true pathway to energy security.”

Groups Urge Biden to Invoke Defense Production Act to Counter Putin, Accelerate Green Transition

“A renewable energy future,” the groups wrote, “is a peaceful and ultimately more prosperous one.”

Above: Photo / Adobe Stock

A coalition of over 200 groups on Wednesday called on President Joe Biden to leverage his authority under the Defense Production Act to simultaneously “produce alternatives to fossil fuels, fight the climate emergency, combat Putin’s stranglehold on the world’s energy economy, and support the transition to a renewable and just economy.”

“With one fell swoop, you would reduce energy costs and move the world away from fossil fuel markets that are all too easily manipulated by bad actors.”

The demand was delivered in a letter to Biden—signed by groups including the Center for Biological Diversity, Global Witness, and Stand.earth—and follows the administration’s move Tuesday to ban U.S. imports of Russian fossil fuels in response to Russia’s ongoing military attack on Ukraine.

The groups thank Biden for that immediate ban and say it must be followed not by “short-sighted policies” like ramping up domestic drilling, as the U.S. fossil fuel lobby and industry supporters like Sen. Joe Manchin (D-W.Va.) have called for, because that would worsen the climate emergency and “deepen our dependence on fuels that lead to global instability.”

“Oil and gas constitute 40% of Russia’s national revenue, meaning Russian exports of oil and gas are literally funding this invasion,” the letter states.

Ramping up fossil fuel extraction and use would also worsen the climate crisis, the groups note, referencing the latest Intergovernmental Panel on Climate Change report releasedlast week showing that “natural and human systems” are being driven “beyond their ability to adapt.”

What is needed instead, the letter states, is a massive surge in the deployment of renewable energy.

Biden can lead that effort by utilizing the Defense Production Act (DPA), with specific actions on three fronts, all of which should center communities most impacted by the current fossil fueled-based system. The letter calls on the president to:

  • Rapidly scale up production, manufacturing, and deployment of renewable energy technologies, heat pumps, storage, and weatherization technologies here and abroad. These green technologies can be exported to Ukraine, the rest of Europe, and the Global South to help wean them off of their dependence on Russian fossil fuels. And they should be simultaneously deployed across the United States to jumpstart the renewable energy revolution and prioritize construction in climate-vulnerable communities. With one fell swoop, you would reduce energy costs and move the world away from fossil fuel markets that are all too easily manipulated by bad actors.
  • Create millions of long-term, high-paying domestic jobs and position the U.S. to be a global leader in showcasing the economic benefits of the just and renewable energy transition. Investments by the federal government can create high-quality, family-supporting jobs; and build worker power by including high-road labor standards.
  • Accelerate the transition to zero-emission public transportation, alternatives to car based transportation and related infrastructure domestically, and deploy it nationwide, prioritizing communities who are most vulnerable to the climate emergency. These steps will reduce the burden of higher gas prices at the pump for U.S. residents.

“A renewable energy future,” the groups wrote, “is a peaceful and ultimately more prosperous one.”

Climate advocates have previously linked Russia’s military attack on Ukraine with reliance on fossil fuels.

American author and climate activist Bill McKibben, for example, wrote last month in his newsletter The Crucial Years that “it is a war underwritten by oil and gas” and urged Biden to invoke the DPA to produce “electric heat pumps in quantity, so we can ship them to Europe where they can be installed in time to dramatically lessen Putin’s power. “

Fridays for Future youth activists also took to the streets of cities across the globe last week to #StandWithUkraine and heed a call from the Ukrainian arm of the global climate movement.

In a series of tweets last Thursday, the day of the demonstrations, the global group called this “an eye-opening moment for humanity to see that the world is aflame with new and old wars caused by fossil fuels.”

“We want to call out the era of fossil fuel, capitalism, and imperialism that allows these systemic oppressions,” they said. “We demand a world where leaders prioritize #PeopleNotProfit.”

Climate Crisis Has Made Western US Megadrought Worst in 1,200 Years

“Climate change is here and now,” said Rep. Pramila Jayapal. “If a 1,200 year mega-drought isn’t enough to make people realize that, I don’t know what is.”

The megadrought which has gripped western U.S. states including California and Arizona over the past two decades has been made substantially worse by the human-caused climate crisis, new research shows, resulting in the region’s driest period in about 1,200 years.

Scientists at University of California-Los Angeles, NASA, and Columbia University found that extreme heat and dryness in the West over the past two years have pushed the drought that began in 2000 past the conditions seen during a megadrought in the late 1500s.

“We’re sort of shifting into basically unprecedented times relative to anything we’ve seen in the last several hundred years.”

The authors of the new study, which was published Monday in the journal Nature Climate Change, followed up on research they had conducted in 2020, when they found the current drought was the second-worst on record in the region after the one that lasted for several years in the 16th century.

Since that study was published, the American West has seen a heatwave so extreme it sparked dozens of wildfires and killed hundreds of people and droughtconditions which affected more than 90% of the area as of last summer, pushing the region’s conditions past “that extreme mark,” according to the Los Angeles Times.   

The scientists examined wood cores extracted from thousands of trees at about 1,600 sites across the West, using the data from growth rings in ancient trees to determine soil moisture levels going back to the 800s.

They then compared current conditions to seven other megadroughts—which are defined as droughts that are both severe and generally last a number of decades—that happened between the 800s and 1500s.

The researchers estimated that the extreme dry conditions facing tens of millions of people across the western U.S. have been made about 42% more severe by the climate crisis being driven by fossil fuel extraction and emissions.

“The results are really concerning, because it’s showing that the drought conditions we are facing now are substantially worse because of climate change,” Park Williams, a climate scientist at UCLA and the study’s lead author, told the Los Angeles Times.

In the region Williams and his colleagues examined, the average temperature since the drought began in 2000 was 1.6° Fahrenheit warmer than the average in the previous 50 years. Without the climate crisis driving global temperatures up, the West would still have faced drought conditions, but based on climate models studied by the researchers, there would have been a reprieve from the drought in 2005 and 2006.

“Without climate change, the past 22 years would have probably still been the driest period in 300 years,” Williams said in a statement. “But it wouldn’t be holding a candle to the megadroughts of the 1500s, 1200s, or 1100s.”

Rep. Pramila Jayapal (D-Wash.) said the new research must push the U.S. Congress to take far-reaching action to mitigate the climate crisis, as legislation containing measures to shift away from fossil fuel extraction and toward renewable energy is stalled largely due to objections from Republicans and right-wing Democratic Sen. Joe Manchin of West Virginia.

“It’s time for Congress to act by making meaningful investments into climate action—before it’s too late,” she said.

The drought has had a variety of effects on the West, including declining water supplies in the largest reservoirs of the Colorado River—Lake Mead and Lake Powell— as well as reservoirs across California and the Great Salt Lake in Utah.

According to the U.S. Drought Monitor, 96% of the Western U.S. is now “abnormally dry” and 88% of the region is in a drought.

“We’re experiencing this variability now within this long-term aridification due to anthropogenic climate change, which is going to make the events more severe,” Isla Simpson, a climate scientist at the National Center for Atmospheric Research who was not involved in the study released Monday, told the Los Angeles Times.

The researchers also created simulations of other droughts they examined between 800 and 1500, superimposing the same amount of drying driven by climate change. In 94% of the simulations, the drought persisted for at least 23 years, and in 75% of the simulations, it lasted for at least three decades—suggesting that the current drought will continue for a number of years.

Williams said it is “extremely unlikely that this drought can be ended in one wet year.”

“We’re sort of shifting into basically unprecedented times relative to anything we’ve seen in the last several hundred years,” Samantha Stevenson, a climate modeler at the University of California, Santa Barbara who was not involved in the study, told the New York Times.

Study Exposes How World’s Biggest Corporations Embellish Climate Progress

Video

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.

click to watch

“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 a warming climate can bring bigger snowstorms

Video

Above: Photo by Josh Hild from Pexels

The blizzard that buried Boston under nearly 2 feet of snow in January 2022 was historic, but not a surprise. Over a century of reliable weather records show many of the Northeast’s heaviest snowfalls have occurred since 1990 – including seven of the top 10 in both Boston and New York.

At the same time, winters in the Mid-Atlantic and Northeast have warmed by approximately 4 degrees Fahrenheit (2.2 C) since the late 1800s.

How can the spate of big snowstorms be reconciled with our warming climate? I’m an atmospheric scientist. Let’s look at an important law of physics and some theories that can help explain the changes.

Warmer air, more moisture

First, warmer air can hold more moisture than cold air.

Think of the atmosphere like a sponge. Air holds about 4% more water vapor for each additional degree Fahrenheit increase in temperature (that’s about 7% per degree Celsius). The physical law that explains this relationship is known as the Clausius-Clapyron relation.

This increased atmospheric moisture is helping to intensify the water cycle. The Northeast and Mid-Atlantic have become wetter – not just in winter, but in spring, summer and fall, too. In addition to more total precipitation over a season and year, the additional moisture also fuels extreme events, like more intense hurricanes and flooding rains. The Northeast has seen an increase of more than 50% in the heaviest precipitation events in recent decades, the largest increase of any region of the U.S.

In the early 1900s, winters across the Northeast typically averaged around 22 degrees Fahrenheit. Now, 26 degrees is the official new “normal” temperature, defined as the average over 1991-2020. A few recent winters have been over 30.

In the Northeast, then, we have an environment that has warmed yet is often still below freezing. Put another way, regions of the world that are cold enough for snow have warmed enough to now be visited by storms capable of holding and dropping more moisture. Rather than intense downpours like Louisiana has been seeing lately, the region gets heavy snow.

The warming ocean plays a role

The January blizzard was fueled by ocean waters in the western Atlantic that are warmer than normal. That’s also part of a consistent pattern.

The oceans have been absorbing more than 90% of the additional heat attributable to rising atmospheric greenhouse gases from human activities, particularly burning fossil fuels. The oceans now contain more heat energy than any time since measurements began six decades ago.

Scientists are studying whether global warming may be driving a slowing of the ocean conveyor belt of currents that transport water around the globe. Satellite imagery and ocean measurements show that warmer waters have “piled up” along the East Coast, a possible indication of a slowing of the Atlantic Meridional Overturning Circulation.

Moisture evaporated from ocean water provides much of the energy for both tropical and mid-latitude extra-tropical cyclones, known commonly as nor’easters.

The Arctic influences the snow pattern, too

While tropical storm systems are fueled primarily by warm water, nor’easters gain energy from sharp temperature gradients where cold and warm air masses meet. The frequency of cold air outbreaks is another aspect of climate change that may be contributing to recent increases in extreme snowfall events.

Recent research has suggested that a warming Arctic, including declines in Arctic sea ice and snow cover, is influencing behavior of the polar vortex, a band of strong westerly winds that forms in the stratosphere between about 10 and 30 miles above the Arctic every winter. The winds enclose a large pool of extremely cold air.

When the Arctic is relatively warm, the polar vortex tends to be weaker and more easily elongates or “stretches,” allowing extremely cold air to dip south. Episodes of polar-vortex stretching have markedly increased in the past few decades, leading, at times, to more severe winter weather in some places.

What is the polar vortex? NASA explains.

Arctic amplification, the enhanced warming to our north, may, paradoxically, be helping to shuttle cold air to the Eastern Seaboard during polar vortex disruptions, where the cold air can interact with warmer, moisture-laden air from the warmer-than-normal western Atlantic Ocean. The most recent stretched polar vortex event helped to bring together key ingredients for the historic blizzard.

What’s ahead?

Global climate models project an increase in the most extreme snowfall events across large areas of the Northern Hemisphere with future warming. In some other parts of the world, like Western Europe, intensification of the hydrological cycle will mean more winter rain than snow as temperatures rise.

For the east coast of North America, as well as Northern Asia, winter temperatures are expected to still be cold enough for storms to bring heavy snow – at least through mid-century. Climate models suggest that extreme snowfalls will become rarer, but not necessarily less intense, in the second half of the century, as more storms produce rain.

The sharp increase in high-impact Northeast winter storms is an expected manifestation of a warming climate. It’s another risk the U.S. will have to prepare for as extreme events become more common with climate change.

It Is ‘Strange,’ Says Greta Thunberg, That Biden Is Seen as a Climate Leader

Video
Greta Thunberg’s passions erupt at cop26’s global greenwashing Fest

“The U.S. is actually expanding fossil fuel infrastructure,” the 18-year-old Swedish climate activist said in a new interview.

In an interview published in The Washington Post Magazine on Monday, Swedish activist Greta Thunberg said it is “strange” that some consider U.S. President Joe Biden a climate leader even as his administration fails to take the ambitious steps necessary to tackle the intensifying planetary crisis.

When asked whether she is “inspired” by Biden or other world leaders, Thunberg pointed out that “the U.S. is actually expanding fossil fuel infrastructure” under the current administration.

“I’ve met so many people who give me very much hope and just the possibility that we can actually change things.”

“Why is the U.S. doing that?” she asked. “It should not fall on us activists and teenagers who just want to go to school to raise this awareness and to inform people that we are actually facing an emergency.”

“People ask us, ‘What do you want?’ ‘What do you want politicians to do?'” added Thunberg, who helped spark a global, youth-led climate protest movement with a solo strike outside of the Swedish Parliament building in 2018. “And we say, first of all, we have to actually understand what is the emergency.”

“We are trying to find a solution of a crisis that we don’t understand,” she continued. “For example, in Sweden, we ignore—we don’t even count or include more than two-thirds of our actual emissions. How can we solve a crisis if we ignore more than two-thirds of it? So it’s all about the narrative.”

While Biden has touted his decision to bring the U.S. back into the Paris agreement, his pledge to cut the nation’s greenhouse gas emissions in half by 2030, and other initiatives as a show of leadership in the face of an existential threat to humanity, his administration has also approved oil and gas drilling permits at a faster rate than former President Donald Trump’s did.

During Biden’s presidency, according to a report released earlier this month by the consumer advocacy group Public Citizen, the Bureau of Land Management (BLM) has approved an average of 333 oil and gas drilling permits per month this year alone—40% more than it did over the first three years of Trump’s White House tenure.

“When it comes to climate change policy, President Biden is saying the right things. But we need more than just promises,” Alan Zibel, the lead author of the report, said in a statement. “The reality is that in the battle between the oil industry and Biden, the industry is winning. Despite Biden’s campaign commitments to stop drilling on public lands and waters, the industry still has the upper hand. Without aggressive government action, the fossil fuel industry will continue creating enormous amounts of climate-destroying pollution exploiting lands owned by the public.”

Thunberg’s interview with the Post came at the end of a year that saw planet-warming carbon dioxide emissions quickly rebound to pre-pandemic levels as the U.S. and other major nations continued to burn fossil fuels at an alarming and unsustainable rate.

As Glen Peters of the Center for International Climate Research noted Tuesday, “2021 saw the second-biggest absolute increase in fossil CO2 emissions ever recorded.”

Despite the failure of world leaders to act with sufficient urgency as the climate crisis fuels devastating extreme weather events across the globe, Thunberg said she is “more hopeful now” than she was when she kicked off her lonely school strike in 2018.

“In one sense, we’re in a much worse place than we were then because the levels of CO2 in the atmosphere are higher and the global emissions are still rising at almost record speed. And we have wasted several years of blah, blah, blah,” said Thunberg. “But then, on another note, we have seen what people can do when we actually come together.”

“I’ve met so many people who give me very much hope and just the possibility that we can actually change things,” she added. “That we can treat a crisis like a crisis.”

Top US Banks and Investors Responsible for Nearly as Much Emissions as Russia, Report Finds

Above: Collage by Lynxotic, Original Photo by Unsplash

“Wall Street’s toxic fossil fuel investments threaten the future of our planet and the stability of our financial system and put all of us, especially our most vulnerable communities, at risk.”

Fueling fresh calls for swift, sweeping action by President Joe Biden and financial regulators, a report published Tuesday reveals that if the planet-heating pollution of the 18 largest U.S. asset managers and banks is compared to that of high-emissions countries, Wall Street is a top-five emitter.

“Financial regulators have the authority to rein in this risky behavior, and this report makes it clear that there is no time to waste.”

The new report—entitled Wall Street’s Carbon Bubble: The global emissions of the U.S. financial sector—was released by the Center for American Progress (CAP) and Sierra Club. The analysis was done by South Pole, which replicated an approach it used earlier this year for a U.K.-focused effort commissioned by Greenpeace and the World Wide Fund for Nature (WWF).

Though likely a “gross underestimate,” as Sierra Club put it, because the analysis relies on public disclosures that exclude key data, the researchers found that “just the portions of the portfolios of the eight banks and 10 asset managers studied in this report financed an estimated total of 1.968 billion tons CO2e based on year-end disclosures from 2020.”

Putting that CO2e—or carbon dioxide equivalent, which is used to compare emissions from various greenhouse gases—figure into context, the report notes:

  • If the financial institutions (FIs) in this study were a country, they would have the fifth largest emissions in the world, falling just short of Russia;
  • Financed emissions from the 18 institutions covered in this report are equivalent to 432 million passenger vehicles driven for one year;
  • Financed emissions from the eight banks studied in this report are equivalent to 80 million homes’ energy use for one year; and
  • Financed emissions from the 10 asset managers studied in this report are equivalent to three billion barrels of oil consumed.

The banks analyzed are Bank of America, Bank of New York (BNY) Mellon, Citigroup, Goldman Sachs, JPMorgan Chase, Morgan Stanley, State Street, and Wells Fargo.

The asset managers included are BNY Mellon Investment Management, BlackRock, Capital Group, Fidelity Investments, Goldman Sachs Asset Management, JPMorgan Asset Management, Morgan Stanley Investment Management, PIMCO, State Street Global Advisors, and the Vanguard Group.

When Wall Street is factored into the list of the world’s top 10 countries responsible for the most annual greenhouse gas emissions, it falls after China, the United States, India, and Russia but ranks ahead of Indonesia, Brazil, Japan, Iran, and Germany, according to Climate Watch data.

As the new publication warns:

The findings of this report make clear that the U.S. financial sector is a major contributor to climate change. Given that the indirect emissions of the U.S. financial sector are just below the total emissions of Russia, it should be considered a high-carbon sector and treated as such. Therefore, if President Biden and his administration do not put in place measures to mitigate U.S.-financed emissions, the United States will almost certainly fall far short of its targets to achieve a 50% to 52% reduction from 2005 levels in 2030 and net-zero emissions economy-wide by no later than 2050.

The implications of falling short would be dire. Continued unfettered emissions supported by the financial industry would mean that the deadly wildfires, droughts, heatwaves, hurricanes, floods, and other extreme weather events that Americans and communities around the world are already experiencing will only become worse, and efforts to mitigate emissions will only become more challenging and costly.

Representatives from the groups behind the report echoed its call to action in a statement Tuesday.

“Climate change poses a large systemic risk to the world economy. If left unaddressed, climate change could lead to a financial crisis larger than any in living memory,” said Andres Vinelli, vice president of economic policy at CAP. “The U.S. banking sector is endangering itself and the planet by continuing to finance the fossil fuel sector.”

Vinelli added that “because the industry has proven itself to be unwilling to govern itself,” regulators including the U.S. Securities and Exchange Commission and Office of the Comptroller of the Currency “must urgently develop a framework to reduce banks’ contributions to climate change.”

Ben Cushing, Sierra Club’s Fossil-Free Finance campaign manager, agreed that “regulators can no longer ignore Wall Street’s staggering contribution to the climate crisis.”

“The U.S. banking sector is endangering itself and the planet by continuing to finance the fossil fuel sector.”

“Wall Street’s toxic fossil fuel investments threaten the future of our planet and the stability of our financial system and put all of us, especially our most vulnerable communities, at risk,” he said. “Financial regulators have the authority to rein in this risky behavior, and this report makes it clear that there is no time to waste.”

The report comes as financial institutions worldwide face mounting criticism for their contributions to the climate emergency—including at the COP26 climate summit in Scotland last month—and as the Koch-funded American Legislative Exchange Council (ALEC) is pushing model legislation that opposes fossil fuel divestment.

More than three dozen climate advocacy groups argued Monday that “what ALEC claims to be discriminatory action”—referring to divestment from major polluters—”is instead prudent action to ensure the stability of our financial system and economy.”

“We know from the Great Recession that the financial sector won’t take responsibility,” the organizations noted. “It’s up to regulators to protect people from the impact on climate and financial risk of fossil fuel investment.”
