A New Book Dives Deep Into the Climate and Health Impacts of Gas Stoves

News Feed
Wednesday, August 14, 2024

Each year, 100,000 Americans die from coal and car pollution. And each year, 20 percent of deaths worldwide are attributable to fossil fuel use. Rob Jackson, Stanford climate scientist and chair of the Global Carbon Project, keeps a long list of statistics like these—on the devastating health impacts of fossil fuels—ready to share. “That’s 10 million senseless deaths [due to fossil fuels] when we have cleaner fuels available,” Jackson explained to Civil Eats as he prepped for the launch of his new book, Into the Clear Blue Sky: The Path to Restoring Our Atmosphere. “One reason I push the intersection between health and climate is because it reaches people who won’t otherwise pay attention to climate.” That intersection hits home in about 40 percent of U.S. kitchens, where Americans still cook over flames powered by natural gas. The week of Jackson’s book launch, many of those cooks were probably drenched in sweat, too: July 22 was the hottest day ever recorded on Earth. In the book, Jackson tells stories of measuring both the staggering greenhouse gas emissions gas stoves produce and the dangerous levels of air pollutants home cooks breathe in as they sauté and roast (even long after the burners are off). Last year, some of those measurements, published in research studies, contributed to public awareness that quickly spiraled into what multiple media outlets branded “gas stove culture wars.” (Just last week, Senator JD Vance told his supporters Vice President Kamala Harris “wants to take away your gas stoves,” which is entirely false.) But Into the Clear Blue Sky  is a solutions book written by a scientist, and Jackson approaches the phaseout of gas-powered home appliances with the same steady, measured urgency he applies to exploring decarbonizing steel and electrifying vehicles—two other important solutions in his book. Also, early on, he establishes a throughline: that the impacts of the climate crisis are unequally felt, and solutions need to be accessible and applicable to all. Jackson spoke to Civil Eats about his groundbreaking research, the pushback against policies that could speed electrification, and how writing about climate solutions—gas stove phaseouts and otherwise—has left him angry and afraid, but also hopeful. You set out to write about climate solutions, and you allotted two chapters to the food system—one on gas stoves, one on beef. Considering all the ways that climate change intersects with the food system, why those two? For a couple of reasons. In the book, I highlight the opportunities for reducing methane concentrations in the atmosphere as probably our best short-term goal for climate action. And the two largest sources of methane in the world are food: primarily cows and rice paddies, and gas appliances in our homes and buildings. We did the first studies looking at emissions from water heaters and have spent the last five years studying gas stoves—initially, purely for their greenhouse gas emissions, to see how much methane leaks into the air. We found that the leaks from gas stoves alone in the U.S. were responsible for pollution equivalent to half a million U.S. cars. But as we were going into hundreds of homes measuring methane, we started measuring indoor air pollutants like NOx [nitrogen oxide] gasses, which triggers asthma, and benzene, which is carcinogenic. That opened a whole new field of study for me, because I realized every time I turned on a burner on a gas stove or started the oven, pollution levels shot up above health benchmarks, even when I had the ventilation hood on in my house. You wrote that the U.S. Environmental Protection Agency (EPA) doesn’t include methane leakage from gas appliances in their greenhouse gas emissions estimates. Is that still true, or has your research changed things? It’s still mostly true. They do now include some emissions from gas stoves, but they don’t include the full set of emissions, including leakage. I began measuring methane from appliances in homes and buildings because it was the least-studied part of the gas supply chain, and I wanted to fill a fill a research gap there. Our research has drawn a lot of attention to the issue of gas appliances in our homes. The largest source of emissions indoors is the furnace, because it burns so much more gas. But the furnace and the water heater are required to vent directly outdoors through a chimney or a pipe. I focus a lot on gas stoves because there’s no vent. Or there’s a hood that most people don’t use—and that surveys show often isn’t effective. The levels of air pollutants you’ve measured in people’s homes are unbelievably high. In the book, you talk about how the industry knew about the health concerns more than 100 years ago, to the extent that their own experts said gas shouldn’t be used in homes without requiring hoods that vented to the outside, which didn’t happen. How much of this evidence on indoor air pollutants and the health implications is just emerging now and how much is new? It’s a fascinating question. For example, there’s 50 years of measurements on NOx pollution indoors. There were meta-analyses done in the 1990s showing that stoves increased indoor NOx levels and that the likelihood of asthma and wheezing and different health outcomes increased if you lived in a home with a gas stove. So, that knowledge was well known 30 years before I ever thought about measuring gas stoves. I think our instruments are better now, and we have a finer-scale resolution. And until we did it, no one had measured benzene emissions indoors from gas stoves. So, we’re still learning about the full set of pollutants that are generated indoors. And I think we’re learning more now about not just the emission rates but the concentrations that people actually breathe. That’s the tricky part, because what you need to know for predicting health outcomes is how high the levels are—not just in the kitchen but in the bedrooms down the hall where people spend their time and sleep. That was the biggest surprise of our studies for me—the fact that concentrations of pollutants rose so quickly in bedrooms down the hall and stayed above health benchmarks for hours after the stove was off. When you think about cooking meal after meal, day after day, month after month and these concentrations just recurring all the time in our homes . . . sometimes I think we would never willingly stand over the tailpipe of a car breathing in the exhaust, but we willingly stand over a gas stove and breathe the same pollutants. Have you done any of this research in restaurants? We are doing that right now, literally. I have a part of my lab up in Pittsburgh doing measurements. We’ve done some in the Bay Area. We’re doing some in the Midwest, and we’re going to go to Washington, D.C. this summer and do some more. Generally, [commercial] kitchens have industrial hoods, which are much better. However, they also have many more burners. And they have pilot lights, which are the most inefficient way that we burn. So, I worry about exposures where the concentration is building up at night after the restaurant closes and the hoods are off and these pilot lights are burning. I worry more about small kitchens . . . somewhere where maybe the ventilation is not so good. We’re really trying to understand the risks in kitchens and, frankly, to do it more positively. We’re trying to work with chefs to promote the benefits of electrification. There’s an increasing number of chefs willing to speak out and say, “Yes, I can cook with electricity and there’s no reason not to switch now.” In terms of electrification, you talk a lot in the book about how climate solutions need to be accessible to everyone. Switching to induction from gas can be really costly. How do you see the transition becoming possible for people at all income levels? I do think the cost will come down over time. But I think of climate solutions [as having] two flavors: One is to use less of whatever it is that emits fossil fuels. The other is to decarbonize whatever infrastructure is left. And we can’t really cook less, so that’s not a realistic solution set for our homes. So, I think we need to favor reach codes that require future construction to be all electric. Governor [Kathy] Hochul and the Assembly and Senate in New York passed the country’s first state-level bill requiring new homes and buildings be all-electric by 2026. Those bills make sense to me, because every time we plumb a new house or new building with gas infrastructure or fossil fuel infrastructure, we lock in greenhouse gases for decades to come. I don’t suggest that we need to go into every home and rip people’s stoves off the walls. We need an orderly transition, and the place to do that is when our stoves reach the end of their lifetime, to switch them out. Since I am fortunate and relatively wealthy, I chose to replace my gas stove with an induction stove before the end of its lifetime because I could. But the hundreds of homeowners we sample in Bakersfield and lower-income neighborhoods, they don’t have that option, and even if they can afford it, they rent. So, I worry the most about people in lower-income communities. There’s also been a lot of pushback. Are you optimistic about these electrification laws moving forward? The industry is powerful. The reach codes that Berkeley passed have been overturned. There were 100 cities and counties in California that had passed similar reach codes, and most of those are now moot. States like New York have taken a different approach, and I’m optimistic that states that want to act will find a way to incentivize the transition to electric appliances. But there have now been a couple of dozen states that have passed preemption laws to make such codes illegal. Though there’s tremendous pushback, I think induction stoves will win eventually, because they’re a better product. They’re more efficient. A child can’t burn their hand. But [with climate], winning slowly is the same as losing, as Bill McKibben likes to say. On that note, my editor suggested I ask you about what gives you hope, and I felt myself having an emotional reaction. Like, “I don’t care about hope! I care about what’s possible. Brass tacks. What can be done—or not—to move the needle?” But you use the word hope a lot in the book, so I thought I should ask: Why? I would say that hope and optimism are muscles that we need to exercise. My first homework assignment in any class is for students to go home and research things in the environment that are better today than they were 50 years ago. That list is long. It’s lifespan and childhood mortality. It’s water and air quality. It’s a decline in global poverty, despite the injustices that remain. Then there’s a long list of targeted regulations that have saved us money and made us healthier. The phaseout of leaded gasoline has literally made us smarter and made lead levels in our kids’ blood drop 95 percent. There’s the Montreal Protocol that saved billions of cases of skin cancers and cataracts. And there’s my favorite example—the Clean Air Act—that saves 100,000 American lives a year, a bipartisan bill at a 30-fold return on investment. So, I think by acknowledging past successes we make future successes in climate more likely, because we can see a path to a better future. And I guess I believe strongly that it’s very easy in my world to sink only into the latest statistics of drought and disasters—but it doesn’t seem to motivate people. So, it’s a sort of hope grounded in facts and history. Yes, but the undercurrent is there, which is, you know, I’m afraid and angry, because we’ve wasted decades. We’ve sprinted right to 1.5°C—something that people thought was unfathomable 20 years ago—and we seem to be sprinting towards 2°C. So yes, I’m hopeful, but I’m also angry and afraid for all of us. Given the urgency, do you think that this upcoming election could partially determine whether catastrophic outcomes are locked in? I’m an environmental scientist, and at this point in my life, there’s only one party that seems to take climate and the environment seriously. It wasn’t always that way. My biggest regret is how politicized and polarized the environment has become. Republican administrations created the EPA and signed the Montreal Protocol. Even Margaret Thatcher, she once said something like, “We have treated the atmosphere like a dust bin.” She of course backtracked later in her career, but she was a chemist and scientist, and she understood. I regret the fact that we are in a place where a Republican who mentions climate gets defeated in a primary by someone farther to the right. I don’t want to pick parties, but I’m deeply concerned about this election. We can’t afford another administration undoing climate rules. It isn’t just for the climate. It’s killing millions of people around the world and hundreds of thousands of Americans. Let’s be frank about it.

Are Dairy Digesters the Renewable Energy Answer or a ‘False Solution’ to Climate Change? $2 Billion for Farmer Discrimination. On July 31, Secretary of Agriculture Tom Vilsack announced that the U.S. Department of Agriculture (USDA) had successfully distributed more than $2 billion to 43,000 farmers who had experienced discrimination while attempting to secure USDA loans. The announcement marked a historic moment in a long saga. Farmers have alleged discrimination in the agency’s loan programs for decades, and multiple lawsuits have been filed over the years by women, Indigenous, and Black farmers who said they were treated differently when applying for loans, driving many out of business. In 2020, lawmakers set aside $4 billion specifically to compensate Black farmers for race-based discrimination, but the program was thrown out in the wake of lawsuits, many of which were filed by Republican officials who alleged discrimination against white farmers. So when Democrats passed the Inflation Reduction Act, they authorized a new, race-neutral fund that would compensate any farmer who alleged discrimination based on race, ethnicity, gender, and other factors. During a press call announcing the news, Vilsack said the agency received 58,000 applications and ultimately approved 43,000. While the agency could not compensate farmers for losses or pain endured, he said, “I think it represents USDA acknowledging and responding to reported discrimination.” Vilsack could not provide statistics on how many of the individuals who received funding were Black farmers, but said that analysis may become available in the future. He also pointed out that the states with the most farmers awarded funding were Mississippi and Alabama. In addition to the payments, he said the agency has been working to root out and prevent future discrimination and break down barriers to access within its loan programs with, for example, “new processes that reduce the need for human discretion in loan decision-making.” Many Democrats in Congress and advocacy organizations released statements applauding the USDA’s progress on the issue. “Today marks an important milestone for USDA and for our collective efforts to hold the Department accountable in addressing a history of acts of discrimination against perpetually marginalized agricultural producers and their communities,” said Michelle Hughes, Co-Executive Director of the National Young Farmers Coalition, in a press release. The coalition was one of the cooperating organizations, along with others like the Federation of Southern Cooperatives, that helped the USDA get the word out to farmers about the application process.

According to a report published last week by the Midwestern Prairie Rivers Network (PRN), herbicides sprayed primarily on row crops in Illinois are drifting far from targeted fields, damaging trees and other plant life. Researchers at PRN monitored symptoms of pesticide drift—such as curled leaves—and collected tissue samples from plants over six years. They found symptoms of drift during 677 out of 679 total visits to nearly 300 sites. Of 127 tissue samples taken from trees and other plants, 90 percent contained herbicide residues. Herbicides detected included 2,4-D, atrazine, dicamba, glyphosate, and seven others. Many of the sites where researchers documented incidents of drift were more than 500 feet from the likely source of exposure, suggesting the chemicals are drifting significant distances. “Our monitoring and tissue sampling program indicates that current legal safeguards/protections and regulatory efforts are inadequate at protecting people and the environment from herbicide drift,” the researchers wrote. At a press conference for the release of the report, co-author Kim Erndt-Pitcher said the results pointed to the fact that herbicides are playing a significant role in the decline of tree health across the state, and residents and farmers expressed concerns about potential risks to animals and their families’ health. Patsy Hopper, an organic farmer and landowner south of Urbana, Illinois, said her land long produced a bounty of fruits and vegetables. At one point in time, she remembered harvesting 50 gallons of cherries in a season. “In the past few years, we’ve hardly had a harvest because of pesticide drift. The trees are dying,” she said. “This year, we had enough cherries for one pie.” Read More: Beyond Damaging Crops, Dicamba Is Dividing Communities EPA Weakens Safeguards for Weed Killer Atrazine, Linked to Birth Defects Farm-State Veep. On August 6, Vice President and Democratic presidential candidate Kamala Harris chose Tim Walz as her running mate, catapulting agriculture and other food issues into the 2024 presidential election in a new way. As a member of the House of Representatives, Walz served on the Agriculture Committee. There, he played a role in three farm bill cycles, sponsoring various proposals focused on expanding on-farm conservation efforts and supporting beginning farmers and ranchers. As Governor of Minnesota, Walz has advocated for biofuels, a key priority of commodity ag groups, and local advocates for small farms say he fought consolidation to keep more farmers on the land. He also championed and ultimately signed into law a universal school meals program in the state. Read more: States Are Fighting to Bring Back Free School Meals This Farm Bill Really Matters.

The trees are dying,” she said. “This year, we had enough cherries for one pie.”

Farm-State Veep. On August 6, Vice President and Democratic presidential candidate Kamala Harris chose Tim Walz as her running mate, catapulting agriculture and other food issues into the 2024 presidential election in a new way.

As a member of the House of Representatives, Walz served on the Agriculture Committee. There, he played a role in three farm bill cycles, sponsoring various proposals focused on expanding on-farm conservation efforts and supporting beginning farmers and ranchers.

As Governor of Minnesota, Walz has advocated for biofuels, a key priority of commodity ag groups, and local advocates for small farms say he fought consolidation to keep more farmers on the land. He also championed and ultimately signed into law a universal school meals program in the state.

Fire Disrupts UN Climate Talks Just as Negotiators Reach Critical Final Days

Fire has disrupted United Nations climate talks, forcing evacuations of several buildings with just two scheduled days left and negotiators yet to announce any major agreements

BELEM, Brazil (AP) — Fire disrupted United Nations climate talks in Brazil on Thursday, forcing evacuations of several buildings with just two scheduled days left and negotiators yet to announce any major agreements. Officials said no one was hurt.The fire was reported in an area of pavilions where sideline events are held during the annual talks, known this year as COP30. Organizers soon announced that the fire was under control, but fire officials ordered the entire site evacuated for safety checks and it wasn't clear when conference business would resume.Viliami Vainga Tone, with the Tonga delegation, had just come out of a high-level ministerial meeting when dozens of people came thundering past him shouting about the fire. He was among people pushed out of the venue by Brazilian and United Nations security forces.Tone called time the most precious resource at COP and said he was disappointed it's even shorter due to the fire.“We have to keep up our optimism. There is always tomorrow, if not the remainder of today. But at least we have a full day tomorrow,” Tone told The Associated Press.A few hours before the fire, U.N. Secretary-General António Guterres urged countries to compromise and “show willingness and flexibility to deliver results,” even if they fall short of the strongest measures some nations want.“We are down to the wire and the world is watching Belem,” Guterres said, asking negotiators to engage in good faith in the last two scheduled days of talks, which already missed a self-imposed deadline Wednesday for progress on a few key issues. The conference, with this year's edition known as COP30, frequently runs longer than its scheduled two weeks.“Communities on the front lines are watching, too — counting flooded homes, failed harvests, lost livelihoods — and asking, ‘how much more must we suffer?’” Guterres said. "They’ve heard enough excuses and demand results.” On contentious issues involving more detailed plans to phase out fossil fuels and financial aid to poorer countries, Guterres said he was “perfectly convinced” that compromise was possible and dismissed the idea that not adopting the strongest measures would be a failure.Guterres was more forceful in what he wanted rich countries to do for poor countries, especially those in need of tens of billions of dollars to adapt to the floods, droughts, storms and heat waves triggered by worsening climate change. He continued calls to triple adaptation finance from $40 billion a year to $120 billion a year.“No delegation will leave Belem with everything it wants, but every delegation has a duty to reach a balanced deal,” Guterres said.“Every country, especially the big emitters, must do more,” Guterres said.Delivering overall financial aid — with an agreed goal of $300 billion a year — is one of four interconnected issues that were initially excluded from the official agenda. The other three are: whether countries should be told to toughen their new climate plans; dealing with trade barriers over climate and improving reporting on transparency and climate progress.More than 80 countries have pushed for a detailed “road map” on how to transition away from fossil fuels, like coal, oil and natural gas, which are the chief cause of warming. That was a general but vague agreement two years ago at the COP in Dubai. Guterres kept referring to it as already being agreed to in Dubai, but did not commit to a detailed plan, which Brazilian President Luiz Inácio Lula da Silva pushed for earlier in a speech.The Associated Press’ climate and environmental coverage receives financial support from multiple private foundations.

Engineered microbes could tackle climate change – if we ensure it’s done safely

Engineering microbes to soak up more carbon, boost crop yields and restore former farmland is appealing. But synthetic biology fixes must be done thoughtfully

Yuji Sakai/GettyAs the climate crisis accelerates, there’s a desperate need to rapidly reduce carbon dioxide levels in the atmosphere, both by slashing emissions and by pulling carbon out of the air. Synthetic biology has emerged as a particularly promising approach. Despite the name, synthetic biology isn’t about creating new life from scratch. Rather, it uses engineering principles to build new biological components for existing microorganisms such as bacteria, microbes and fungi to make them better at specific tasks. By one recent estimate, synthetic biology could cut more carbon than emitted by all passenger cars ever made – up to 30 billion tonnes – through methods such as boosting crop yields, restoring agricultural land, cutting livestock methane emissions, reducing the need for fertiliser, producing biofuels and engineering microbes to store more carbon. According to some synthetic biologists, this could be a game-changer. But will it prove to be? Technological efforts to “solve” the climate problem often verge on the improbably utopian. There’s a risk in seeing synthetic biology as a silver bullet for environmental problems. A more realistic approach suggests synthetic biology isn’t a magic fix, but does have real potential worth exploring further. Engineering microorganisms is a controversial practice. To make the most of these technologies, researchers will have to ensure it’s done safely and ethically, as my research points out. What potential does synthetic biology have? Earth’s oceans, forests, soils and other natural processes soak up over half of all carbon emitted by burning fossil fuels. Synthetic biology could make these natural sinks even more effective. Some researchers are exploring ways to modify natural enzymes to rapidly convert carbon dioxide gas into carbon in rocks. Perhaps the best known example is the use of precision fermentation to cut methane emissions from livestock. Because methane is a much more potent greenhouse gas than carbon dioxide, these emissions account for roughly 12% of total warming potential from greenhouse emissions. Bioengineered yeasts could absorb up to 98% of these emissions. After being eaten by cattle or other ruminants these yeasts block production of methane before it can be belched out. Synthetic biology could even drastically reduce how much farmland the world needs by producing food more efficiently. Engineered soil microbes can boost crop yields at least by 10–20%, meaning more food from less land. Precision fermentation can be used to produce clean meat and clean milk with much lower emissions than traditional farming. Engineered microbes have the potential to boost crop yields considerably. Collab Media/Unsplash, CC BY-NC-ND If farms produce more on less land, excess farmland can be returned to nature. Wetlands, forests and native grasslands can store much more carbon than farmland, helping tackle climate change. Synthetic biology can be used to modify microbe and algae species to increase their natural ability to store carbon in wetlands and oceans. This approach is known as natural geoengineering. Engineered crops and soil microbes can also lock away much more carbon in the roots of crops or by increasing soil storage capacity. They can also reduce methane emissions from organic matter and tackle pollutants such as fertiliser runoff and heavy metals. Sounds great – what’s the problem? As researchers have pointed out, using this approach will require a rollout at massive scale. At present, much work has been done at smaller scale. These engineered organisms need to be able to go from Petri dishes to industrial bioreactors and then safely into the environment. To scale, these approaches have to be economically viable, well regulated and socially acceptable. That’s easier said than done. First, engineering organisms comes with the serious risk of unintended consequences. If these customised microbes release their stored carbon all at once during a drought or bushfire, it could worsen climate change. It would be very difficult to control these organisms if a problem emerges after their release, such as if an engineered microbe began outcompeting its rivals or if synthetic genes spread beyond the target species and do unintended damage to other species and ecosystems. It will be essential to tackle these issues head on with robust risk management and forward planning. Second, synthetic biology approaches will likely become products. To make these organisms cheaply and gain market share, biotech companies will have an incentive to focus on immediate profits. This could lead companies to downplay actual risks to protect their profit margins. Regulation will be essential here. Third, some worthwhile approaches may not appeal to companies seeking a return on investment. Instead, governments or public institutions may have to develop them to benefit plants, animals and natural habitats, given human existence rests on healthy ecosystems. Which way forward? These issues shouldn’t stop researchers from testing out these technologies. But these risks must be taken into account, as not all risks are equal. Unchecked climate change would be much worse, as it could lead to societal collapse, large-scale climate migration and mass species extinction. Large scale removal of carbon dioxide from the atmosphere is now essential. In the face of catastrophic risks, it can be ethically justifiable to take the smaller risk of unintended consequences from these organisms. But it’s far less justifiable if these same risks are accepted to secure financial returns for private investors. As time passes and the climate crisis intensifies, these technologies will look more and more appealing. Synthetic biology won’t be the silver bullet many imagine it to be, and it’s unlikely it will be the gold mine many hope for. But the technology has undeniable promise. Used thoughtfully and ethically, it could help us make a healthier planet for all living species.

Exclusive-Europe Plans Service to Gauge Climate Change Role in Extreme Weather

By Alison Withers and Kate AbnettCOPENHAGEN (Reuters) -The EU is launching a service to measure the role climate change is playing in extreme weather events like heatwaves and extreme rain, and experts say this could help governments set climate policy, improve financial risk assessments and provide evidence for use in lawsuits.Scientists with the EU's Copernicus Climate Change Service told Reuters the service can help governments in weighing the physical risks posed by worsening weather and setting policy in response. "It's the demand of understanding when an extreme event happens, how is this related to climate change?" said the new service's technical lead, Freja Vamborg.The European Commission did not immediately respond to a Reuters request for comment.The service will perform attribution science, which involves running computer simulations of how weather systems might have behaved if people had never started pumping greenhouse gases into the air and then comparing those results with what is happening today.Funded for about 2.5 million euros over three years, Copernicus will publish results by the end of next year and offer two assessments a month - each within a week of an extreme weather event.For the first time, "there will be an attribution office operating constantly," said Carlo Buontempo, director of Copernicus Climate Change Service. "Climate policy is unfortunately again a very polarized topic," said Friederike Otto, a climate scientist at Imperial College London who helped to pioneer the scientific approach but is not involved in the new EU service. She welcomed the service's plans to partner with national weather services of EU members along with the UK Met and the Red Cross Red Crescent Climate Centre."From that point of view, it also helps if the governments do it themselves and just see themselves really the evidence from their own weather services," Otto said. Some independent climate scientists and lawyers cheered the EU move. "We want to have the most information available," said senior attorney Erika Lennon at the non-profit Center for International Environmental Law."The more information we have about attribution science, the easier it will be for the most impacted to be able to successfully bring claims to courts."By calculating probabilities of climate change impacting weather patterns, the approach also helps insurance companies and others in the financial sector.In a way, "they're already using it" with in-house teams calculating probabilities for floods or storms, said environmental scientist Johan Rockstroem with the Potsdam Institute for Climate Impact Research."Financial institutions understand risk and risk has to be quantified, and this is one way of quantifying," Rockstroem said.In litigation, attribution science is also being used already in calculating how much a country's or company's emissions may have contributed to climate-fuelled disasters.The International Court of Justice said in July that attribution science is legally viable for linking emissions with climate extremes - but it has yet to fully be tested in court. A German court in May dismissed a Peruvian farmer's lawsuit against German utility RWE for emissions-driven warming causing Andean glaciers to thaw. The case had used attribution science in calculating the damage claim, but the court said the claim amount was too low to take the case forward.So "the court never got to discussing attribution science in detail and going into whether the climate models are good enough, and all of these complex and thorny questions," said Noah Walker-Crawford, a climate litigation researcher at the London School of Economics. (Reporting by Ali Withers in Copenhagen and Kate Abnett in Belem, Brazil; Writing by Katy Daigle; Editing by David Gregorio)Copyright 2025 Thomson Reuters.

Billionaire hedge fund founder Tom Steyer is running for governor

Billionaire hedge fund founder, climate change warrior and major Democratic donor Tom Steyer is running for governor. Fossil fuel and migrant detention facility investments will likely draw attacks from his fellow Democrats.

Billionaire hedge fund founder Tom Steyer announced Wednesday that he is running for governor of California, arguing that he is not beholden to special interests and can take on corporations that are making life unaffordable in the state.“The richest people in America think that they earned everything themselves. Bulls—, man. That’s so ridiculous,” Steyer said in an online video announcing his campaign. “We have a broken government. It’s been bought by corporations and my question is: Who do you think is going to change that? Sacramento politicians are afraid to change up this system. I’m not. They’re going to hate this. Bring it on.” Protesters hold placards and banners during a rally against Whitehaven Coal in Sydney in 2014.

(Saeed Khan / AFP/Getty Images) Steyer, 68, founded Farallon Capital Management, one of the nation’s largest hedge funds, and left it in 2012 after 26 years. Since his departure, he has become a global environmental activist and a major donor to Democratic candidates and causes. But the hedge firm’s investments — notably a giant coal mine in Australia that cleared 3,700 acres of koala habitat and a company that runs migrant detention centers on the U.S.-Mexico border for U.S. Immigration and Customs Enforcement — will make him susceptible to political attack by his gubernatorial rivals. Steyer has expressed regret for his involvement in such projects, saying it was why he left Farallon and started focusing his energy on fighting climate change.

(Sean Rayford / Getty Images) Steyer previously flirted with running for governor and the U.S. Senate but decided against it, instead opting to run for president in 2020. He dropped out after spending nearly $342 million on his campaign, which gained little traction before he ended his run after the South Carolina primary.Next year’s gubernatorial race is in flux, after former Vice President Kamala Harris and Sen. Alex Padilla decided not to run and Proposition 50, the successful Democratic effort to redraw congressional districts, consumed all of the political oxygen during an off-year election.Most voters are undecided about who they would like to replace Gov. Gavin Newsom, who cannot run for reelection because of term limits, according to a poll released this month by the UC Berkeley Institute of Governmental Studies and co-sponsored by The Times. Steyer had the support of 1% of voters in the survey. In recent years, Steyer has been a longtime benefactor of progressive causes, most recently spending $12 million to support the redistricting ballot measure. But when he was the focus of one of the ads, rumors spiraled that he was considering a run for governor.In prior California ballot initiatives, Steyer successfully supported efforts to close a corporate tax loophole and to raise tobacco taxes, and fought oil-industry-backed efforts to roll back environmental law.His campaign platform is to build 1 million homes in four years, lower energy costs by ending monopolies, make preschool and community college free and ban corporate contributions to political action committees in California elections.Steyer’s brother Jim, the leader of Common Sense Media, and former Biden administration U.S. Surgeon General Vivek Murthy are aiming to put an initiative on next year’s ballot to protect children from social media, specifically the chatbots that have been accused of prompting young people to kill themselves. Newsom recently vetoed a bill aimed at addressing this artificial intelligence issue.
