Repealing the endangerment finding, they wrote, “is contrary to science and the public interest.”

More than 1,000 scientists and other experts on Tuesday sent a letter to US Environmental Protection Agency Administrator Lee Zeldin explaining why they “strenuously object” to his effort to repeal the EPA’s 2009 “endangerment finding,” which has enabled federal climate regulations over the past 15 years.

Amid mounting fears that he would take such action, Zeldin in late July unveiled the rule to rescind the landmark legal opinion that greenhouse gases endanger public health and the welfare of the American people—part of Republican President Donald Trump’s broader pro-polluter agenda.

“As climate scientists, public health experts, and economists, we can attest to the indisputable scientific evidence of human-caused climate change, its harmful impacts on people’s health and well-being, and the devastating costs it is imposing on communities across the nation and around the world,” states the new letter, organized by the Union of Concerned Scientists. “This explicit attempt to undermine or weaken these findings, as well as the critical regulations linked to them, is contrary to science and the public interest.”

“We also strongly oppose the EPA’s reckless dismissal of established climate science as part of its proposal to repeal the endangerment finding, including the agency’s heavy reliance on an unscientific study commissioned by the Department of Energy. This report is rife with inaccuracies, deliberately cherry-picks and mischaracterizes data, and has not undergone a rigorous scientific review process,” the letter continues, echoing an expert review of the government report from earlier this month.

Citing major US and global analyses, along with thousands of independent, peer-reviewed scientific studies, the letter stresses that “the scientific evidence on human-caused climate change and its consequences was unequivocal in 2009 and, since that time, has become even more dire and compelling.”

It says that “based on the best available science,” scientists know:

  • Climate change poses severe harms to human health and well-being;
  • Climate change is clearly increasing the likelihood of extreme events; and
  • The economic toll of climate change is rising.

Harms to human health and well-being include higher rates of heat-related deaths, increased spread of some infectious diseases, and decreased food and water safety due to climate-fueled extreme weather events, the letter says. It also highlights that, according to data from the National Oceanic and Atmospheric Administration (NOAA), “billion-dollar disasters in the United States are on the rise, driven by a combination of climate factors and increased development in disaster-prone areas.”

Despite such findings, the Trump administration is making various moves to boost the planet-wrecking fossil fuel industry and the president withdrew the United States from the Paris Agreement—again—when he returned to office in January. Parties to the 2015 climate agreement aim to limit global temperature rise this century to 1.5°C above preindustrial levels.

“The world stands on the cusp of breaching the 1.5°C (2.7°F) mark on a long-term basis, the global average temperature increase above preindustrial levels that scientists have long warned about,” the experts noted Tuesday. “Communities across the nation are already dealing with devastating and costly climate impacts, that are set to worsen as global warming accelerates. Humanity’s window to act to stave off some of the worst impacts of climate change is fast closing; any further delay is harmful and costly.”

“We urge you to stop dismantling critical climate regulations and evading EPA’s responsibility by pushing disinformation about climate science and impacts,” they concluded. “Instead, we call on you to act with urgency to help address this pressing challenge by limiting heat-trapping emissions. People across the nation are relying on the EPA to fulfill its mission to protect public health and the environment.”

Who Are the Climate Deniers Fighting the Endangerment Finding?

DeSmog has been tracking the efforts of fossil fuel trade associations, policymakers, and industry backed-groups out to demolish U.S. climate policy for years.

In late July, U.S. Environmental Protection Agency (EPA) Administrator Lee Zeldin announced at a trucking facility in Indiana that the Trump administration would be moving to rescind the “endangerment finding,” an agency declaration which provides the legal foundation for many major U.S. climate regulations.

Zeldin was joined at the press conference by U.S. Energy Secretary and former fracking executive Chris Wright, as well as Republican policymakers and representatives of auto groups including the American Trucking Associations (ATA).

This was just a small sampling of a powerful anti-climate coalition that for over a decade has attempted to overturn the endangerment finding, a 2009 scientific determination from the EPA that for the first time recognized carbon dioxide and five other greenhouse gases as  “pollutants” that are “harmful” and therefore must be regulated.

It’s a finding that helps provide the legal justification for EPA regulations on greenhouse gases from power plants, methane pollution from oil and gas operations, and limits on tailpipe emissions from cars and trucks. Now, the Trump administration will be seeking public comments and moving to officially repeal the finding by sometime next year.

DeSmog has been tracking and building databases on the anti-endangerment coalition for years. Below is our guide to the top fossil fuel groups, conservative policymakers, and climate deniers leading the effort to demolish the bedrock of American climate policy.

American Petroleum Institute

When the EPA first issued the endangerment finding in 2009, the American Petroleum Institute (API), the main lobby group for U.S. oil and gas producers, was immediately opposed. “[It] poses an endangerment to the American economy and to every American family,” the institute’s then-president Jack Gerard claimed.

API joined with other fossil fuel and industrial lobby organizations, including the National Association of Manufacturers, to wage an unsuccessful legal challenge against the finding. It recently applauded Zeldin’s announcement of rescinding endangerment and rolling back auto emissions regulations, arguing that the Trump administration is “protecting the freedom of all Americans to decide what they drive.”

U.S. Chamber of Commerce

Another early business opponent of the endangerment finding was the U.S. Chamber of Commerce, a lobby group representing millions of businesses whose membership has included oil and gas majors, fossil fuel utilities, and coal companies. Like API, it helped lead an unsuccessful legal action against the finding.

The Chamber of Commerce has a long record of climate obstruction, including being a member of an infamous climate denial organization known as the Global Climate Coalition. Yet its leadership is now trying to distance itself from Zeldin’s proposed repeal of endangerment, telling Reuters that, “While we did not call for this proposal, we are reviewing it and will consult with members so we can provide constructive feedback to the agency.”

Project 2025

The radical plan for dismantling the U.S. government published by the Heritage Foundation contains specific proposals for the EPA, calling for “a system, with an appropriate deadline, to update the 2009 endangerment finding.” One of the contributors to the EPA chapter is Aaron Szabo, now an assistant administrator at the agency.

Szabo was an advisor to a pro-Trump think tank known as the America First Policy Institute. He was also a former lobbyist “who pushed the interests of major polluters like members of the American Petroleum Institute,” according to Democratic Senator Sheldon Whitehouse, who spoke against Szabo at his EPA confirmation hearing.

One of Project 2025’s top architects, Russ Vought, now leads the White House Office of Management and Budget. He has also called for the repeal of the endangerment finding. “It’s long overdue to look at the impacts on our people of the underlying Obama endangerment finding,” he said in an EPA press release in March. 

Trump’s Climate Working Group

The EPA has justified its repeal of the endangerment finding — which states unequivocally that greenhouse gases are harmful to human health and the climate — by citing a recent Department of Energy report written by five prominent climate crisis deniers.

This so-called “Climate Working Group” includes Steve KooninJohn ChristyRoss McKitrickJudith Curry, and Roy Spencer, all of whom have worked for years to publicly downplay the urgency of the climate crisis or deny that it exists. They argue in their report that carbon dioxide is good for humankind because it boosts “agricultural productivity,” an assessment that isn’t shared by actual climate scientists warning of dire threats to the global food supply from higher global temperatures.      

Heartland Institute

One of the longest-running U.S. climate denial groups, the Heartland Institute was a partner of Project 2025, and for years has advocated against the endangerment finding. It applauded Zeldin’s announcement, saying in a statement that “President Trump is doing the right thing for the economy, the environment, and the American people.”

The Heartland Institute has a major UK ally in Nigel Farage, head of the right-wing political party Reform UK, who last year helped launch a European branch of the denial group. At the Jordan Peterson conference known as the Alliance for Responsible Citizenship (ARC) earlier this year, Farage invoked a frequent climate denier talking point about endangerment, claiming that it’s “absolutely nuts” that carbon dioxide is considered a pollutant.

Koch Network

Climate denial groups that have received funding from foundations linked to the oil and gas billionaires Charles and David Koch are some of the most stalwart opponents of the EPA’s greenhouse gas finding. They include the CO2 Coalition, whose co-founder William Happer was on the National Security Council in Trump’s first administration, as well as the American Energy Alliance and the Competitive Enterprise Institute.

Koch-backed groups have achieved key U.S. Supreme Court victories that have paved way to undo the endangerment finding, including the case West Virginia vs. EPA, which weakened the agency’s ability to address climate change.

Zeldin cited that legal precedent explicitly in his announcement on Tuesday, saying, “would you want the administrator of the EPA to be ignoring the Supreme Court decisions in West Virginia vs. EPA?” He also cited the court’s rejection of the Chevron Deference — a long-standing doctrine giving federal agencies power to interpret the law where vague — which was the result of legal efforts backed in part by Charles Koch.

Critics argue this powerful anti-climate coalition ultimately serves the interest of companies profiting from polluting and warming our atmosphere. Senator Whitehouse said in a statement that “the Trump Administration’s repeal [of the endangerment finding] has the fossil fuel industry’s oily fingerprints all over it.” He added that “Trump chose his fossil fuel megadonors over the American people.”

Trump officials to reconsider whether greenhouse gases cause harm amid climate rollbacks

Donald Trump’s administration is to reconsider the official finding that greenhouse gases are harmful to public health, a move that threatens to rip apart the foundation of the US’s climate laws, amid a stunning barrage of actions to weaken or repeal a host of pollution limits upon power plants, cars and waterways.

Trump’s Environmental Protection Agency (EPA) issued an extraordinary cavalcade of pollution rule rollbacks on Wednesday, led by the announcement it would potentially scrap a landmark 2009 finding by the US government that planet-heating gases, such carbon dioxide, pose a threat to human health.

The so-called endangerment finding, which followed a supreme court ruling that the EPA could regulate greenhouse gases, provides the underpinning for all rules aimed at cutting the pollution that scientists have unequivocally found is worsening the climate crisis.

Despite the enormous and growing body of evidence of devastation caused by rising emissions, including trillions of dollars in economic costs, Trump has called the climate crisis a “hoax” and dismissed those concerned by its worsening impacts as “climate lunatics”.

Lee Zeldin, the EPA administrator, said the agency would reconsider the endangerment finding due to concerns that it had spawned “an agenda that throttles our industries, our mobility, and our consumer choice while benefiting adversaries overseas”.

Environmentalists reacted with horror to the announcement and vowed to defend the overwhelming findings of science and the US’s ability to address the climate crisis through the courts, which regularly struck down Trump’s rollbacks in his first term. “The Trump administration’s ignorance is trumped only by its malice toward the planet,” said Jason Rylander, legal director at the Center for Biological Diversity’s Climate Law Institute.

Come hell or high water, raging fires and deadly heatwaves, Trump and his cronies are bent on putting polluter profits ahead of people’s lives. This move won’t stand up in court. We’re going to fight it every step of the way.”

In all, the EPA issued 31 announcements within just a few hours that take aim at almost every major environmental rule designed to protect Americans’ clean air and water, as well as a livable climate.

Ignoring ‘Science and the Law,’ Trump EPA Readies Chainsaw for Key Climate Finding

“Lee Zeldin is willing to go so far as to break established law to pay back the corporate executives and polluters who spent millions to get Donald Trump elected,” said one climate leader.

Climate advocates said Wednesday that the Trump administration will be abdicating its “clear legal duty to curb climate-changing pollution” if it moves forward with repealing the 16-year-old scientific finding that has underpinned the federal government’s actions to protect people and the planet from fossil fuel emissions.

As The Washington Post reported, Environmental Protection Agency (EPA) Administrator Lee Zeldin is pushing the White House to repeal the endangerment finding, an official determination announced in 2009 that affirmed what the fossil fuel industry had known for decades: that emissions of greenhouse gases including carbon dioxide and methane cause planetary heating and threaten public health.

The finding gave the government the authority to regulate such pollution.

For several days, the White House and EPA refused to release the results of a 30-day review of the endangerment finding, which President Donald Trump called for under an executive order he issued on his first day in office.

Three people with knowledge of the issue, who remained anonymous, told the Post that former EPA Chief of Staff Mandy Gunasekara—who wrote the chapter on the agency in the right-wing policy agenda Project 2025—has been advising the administration on the potential repeal of the endangerment finding.

Another former official from Trump’s first term, attorney Jonathan Brightbill, is also providing legal advice on repealing the scientific finding, which has provided the basis for federal regulations on automobile, aircraft, and power plant emissions.

By repealing the endangerment finding in place, the administration would throw out thousands of scientific studies showing how fossil fuel emissions heat the planet and are linked to heart disease, lung cancer, asthma, and other life-threatening health problems—and clear the way to overturn climate policies introduced by former President Joe Biden.

Denying the science underpinning the finding, said Green New Deal co-sponsor Sen. Ed Markey (D-Mass.), makes the administration “a danger to our country.”

Rachel Cleetus, policy director with the Union of Concerned Scientists’ Climate and Energy Program, said that any attempt by the Trump administration to gut the endangerment finding would be “fully challenged in court.”

“Eliminating the endangerment finding would be a giveaway to the fossil fuel industry, which has spent decades lying to the public about the harms of their product,” said Cleetus. “The science backing the EPA’s finding is rigorous and unequivocal—heat-trapping emissions pose serious threats to public health and well-being. EPA has the authority and legal obligation under the Clean Air Act to regulate sources of these pollutants, including vehicles, power plants, and oil and gas operations.”

Ben Jealous, executive director of the Sierra Club, also warned that the organization “will meet [the EPA] in court” if it moves forward with the repeal.

“Lee Zeldin is willing to go so far as to break established law to pay back the corporate executives and polluters who spent millions to get Donald Trump elected,” said Jealous. “This breathtakingly illegal power grab defies both the Supreme Court and Congress, and if Trump agrees to this plan, the Sierra Club will meet them in court. We will never allow any administration to sell out the climate, our health, our clean air, and our future.”

Zeldin is reportedly recommending that the finding be repealed weeks after wildfires destroyed more than 12,000 homes and other buildings in the Los Angeles area and after meteorologists reported a record 143 days last year of 100°F heat or higher last year. More than 100 people were killed last year by Hurricane Helene, which damaged about 74,000 homes.

“If the Trump EPA proceeds down this path and jettisons the obvious finding that climate change is a threat to our health and welfare, it will mean more polluted air and more catastrophic extreme weather for Americans.”

Experts found that the fires that devastated Los Angeles were made 35% more likely by dry, hot weather conditions and that planetary heating made Helene more dangerous and destructive.

“Any recommendation to strike the finding would be a bad-faith attempt to circumvent the law and best available science with the sole aim of boosting fossil fuel use and the profits of polluting companies,” said Cleetus. “Meanwhile, people around the nation, especially in communities acutely exposed to climate impacts or pollution, will pay the price.”

Dominique Browning, director and co-founder of Moms Clean Air Force, said the new reporting revealed that Zeldin “is contaminating EPA with a virulent strain of climate denial that has seized hold of many of the Trump administration’s Cabinet members.”

Browning noted that the EPA issued its determination in 2009 in response to the 2007 U.S. Supreme Court case Massachusetts v. EPA, which established that the agency has the authority to regulate greenhouse gases.

“EPA’s action respected the ruling of the U.S. Supreme Court,” said Browning. “It respected the bedrock science and respected what we all know to be true: Families across the country are experiencing the extreme weather fueled by climate emissions. With every new supercharged wildfire, hurricane, flood, and heatwave, the danger takes on a terrifying intimacy: Think of the summers that have become too hot for children to play outside, of the lifetime trauma of losing a home in a flood or fire.”

“Administrator Zeldin’s recommendation to strike down the endangerment finding will only bolster the billions of dollars of profit being made by the oil and gas industry—while ransacking our children’s safety,” Browning said.

David Doniger, senior strategist and attorney for climate and energy at the Natural Resources Defense Council, said Zeldin’s reported plan “only makes sense if you consider who would benefit: the oil, coal, and gas magnates who handed the president millions of dollars in campaign contributions.”

The fossil fuel industry poured nearly $450 million into Trump’s campaign, and the president promised to roll back climate regulations if oil and gas companies donated heavily to him in what critics called a quid pro quo.

“This decision ignores science and the law,” said Doniger. “Fifteen years ago, the EPA determined that climate pollution endangers our health and well-being. The Denali-sized mountain of scientific evidence behind that decision has only grown to Mount Everest–size since then. The courts have repeatedly upheld the EPA’s legal authority and its scientific conclusions.”

“This is the clearest example of the Trump administration putting polluters over people, and that’s saying a lot,” Doniger added. “If the Trump EPA proceeds down this path and jettisons the obvious finding that climate change is a threat to our health and welfare, it will mean more polluted air and more catastrophic extreme weather for Americans. We will see them in court.”
