WASHINGTON — When President Trump flies to California on Monday to assess the state’s raging forest fires, he will come face to face with the grim consequences of a reality he has stubbornly refused to accept: the devastating effects of a warming planet.
To the global scientific community, the acres of scorched earth and ash-filled skies across the American West are the tragic, but predictable, result of accelerating climate change. Nearly two years ago, federal government scientists concluded that greenhouse gas emissions from burning fossil fuels could triple the frequency of severe fires across the Western states.
But the president has used his time in the nation’s highest office to aggressively promote the burning of fossil fuels, chiefly by rolling back or weakening every major federal policy intended to combat dangerous emissions. At the same time, Mr. Trump and his senior environmental officials have regularly mocked, denied or minimized the established science of human-caused climate change.
Now, as he battles for a second term in the White House, Mr. Trump has doubled down on his anti-climate agenda as a way of appealing to his core supporters. At a rally in Pennsylvania last month, he blamed California’s failure to “clean your floors” of leaves, threatening to “make them pay for it because they don’t listen to us.”
The lethal fires spreading across the West — like the coronavirus that has ravaged the country for months — are a warning for the president that many voters may hold him and his administration accountable for brushing aside scientific experts and failing to effectively mobilize the government to minimize natural disasters that have claimed lives, damaged property and threatened economic prosperity.
“Talk to a firefighter if you think that climate change isn’t real,” Mayor Eric M. Garcetti of Los Angeles, a supporter of former Vice President Joseph R. Biden Jr., Mr. Trump’s Democratic opponent, said on CNN’s “State of the Union” on Sunday. “It seems like this administration are the last vestiges of the Flat Earth Society of this generation.”
Mr. Trump’s climate record is far more aggressive than the laissez-faire environmental policy promoted for years by business interests in his party. Indeed, as he has sought to zealously roll back regulations, even some of the world’s largest oil companies and automakers have opposed the moves, saying that they will lead to years of legal uncertainty that could actually harm their bottom lines.
“As an historic figure, he is one of the most culpable men in America contributing to the suffering and death that is now occurring through climate-related tragedy,” Jerry Brown, the former California governor who made climate change his signature issue, said in an interview on Sunday, though he was careful not to blame Mr. Trump specifically for the fires ravaging his state.
The president’s record is also more consequential, experts say, because the amount of planet-warming carbon dioxide trapped in the Earth’s atmosphere has now passed the point at which scientists say it would be possible to avert many of the worst effects of global warming — even if tough emissions policies are later enacted.
Mr. Biden’s presidential campaign is hoping to use Mr. Trump’s climate positions as a cudgel against him with independents and moderate Republicans. Christine Todd Whitman, the Republican former governor of New Jersey, is backing Mr. Biden’s candidacy in large part because of the president’s environmental policies.
“It’s mind-boggling, the ignorance that he displays on this subject,” Ms. Whitman said in an interview on Sunday. “He doesn’t understand climate change. He doesn’t particularly believe in science. It’s all about him and his re-election.”
“He doesn’t govern for all Americans,” she said.
On Saturday, Mr. Trump abruptly added the trip to McClellan Park, Calif., near Sacramento, to be briefed on the fires to an already scheduled West Coast fund-raising and campaign swing. He had come under intense criticism for weeks of silence on the increasingly deadly blazes that are consuming parts of California, Oregon and Washington — three Democratic-led states that he has feuded with for years.
White House officials noted that Mr. Trump had signed an executive order in 2018 to minimize the risk of wildfires and urged California and other states to improve forest management.
“Other countries around the world are obsessed with the Paris climate accord, which shackles economies and has done nothing to reduce greenhouse gas emissions, and those on the radical left are pushing the Green New Deal, which would outlaw cows, cars and planes,” said Judd Deere, a White House spokesman. He said Mr. Trump had put in place “common sense policies that have kept our air, water and environment clean.”
But the president has often treated climate change and the environment as a deeply partisan issue, not unlike his handling of the coronavirus pandemic and the recent racial upheaval in some cities, in which he has frequently lashed out at Democratic officials while praising the actions of Republicans.
In Florida last week, Mr. Trump extended a ban on offshore oil drilling supported by the Republican governor in a key election-year state, even though he has refused to do the same for Democratic-led states in the Northeast.
At the event in front of supporters in Jupiter, Fla., Mr. Trump declared himself “a great environmentalist.”
In fact, Mr. Trump has repeatedly mocked the science of climate change since long before he ran for president. In 2012, he tweeted: “In the 1920’s people were worried about global cooling — it never happened. Now it’s global warming. Give me a break!” He also tweeted that the concept of climate change “was created by and for the Chinese in order to make U.S. manufacturing non-competitive.”
The president has continued to take a dim view of climate science throughout his tenure, even as the government he oversees has reinforced the accepted threats to the future of the planet.
In 2017 and 2018, the federal government published a sweeping, two-volume scientific report, the National Climate Assessment, that represents the most authoritative and comprehensive conclusions to date about the causes and effects of climate change in the United States.
The report is clear about the causes — burning fossil fuels — and the effects: It found that the increased drought, flooding, storms and worsening wildfires caused by the warming planet could shrink the American economy by up to 10 percent by the end of the century.
Two days before the White House published the 2018 volume of that report, Mr. Trump mockingly tweeted, “Brutal and Extended Cold Blast could shatter ALL RECORDS — Whatever happened to Global Warming?”
In an interview a month before, he said of global warming, “I don’t know that it’s man-made,” and suggested that even as the planet warmed, “it will change back again” — an idea scientists have long debunked.
Mr. Trump has also stocked his administration with senior officials who have openly questioned the basic science of climate change. The National Oceanic and Atmospheric Administration, which conducts scientific research on climate change, this year hired as a deputy assistant secretary David Legates, a scientist at the University of Delaware who has questioned human-caused global warming. The hiring of Mr. Legates was first reported by NPR.
William Happer, a former senior White House adviser and a Princeton physicist who had gained notoriety in the scientific community for statements that carbon dioxide was beneficial to humanity, began an effort last year to ensure that the next National Climate Assessment did not include worst-case scenarios. Although Mr. Happer left the White House last year, that effort is continuing, according to three people familiar with the matter.
And Mr. Trump’s first appointee to lead the Environmental Protection Agency, Scott Pruitt, declared early in his tenure that carbon dioxide was not a primary contributor to global warming, a statement starkly at odds with the scientific consensus.
“It’s interesting to draw the parallels between Covid and climate change,” said Philip B. Duffy, the president of the Woodwell Climate Research Center, who served on the National Academy of Sciences panel that reviewed the National Climate Assessment. “In both of those cases, Trump personally has refused to recognize the threat.”
“In both cases, there is no plan to deal with crisis,” he added.
Moreover, Mr. Trump has steadily dismantled the climate change plan that was already in place by effectively gutting the federal government’s authority to do anything to lower greenhouse gas pollution.
“We had at the end of the Obama administration the first-ever federalwide regulatory regime on climate,” said David G. Victor, the director of the Laboratory on International Law and Regulation at the University of California, San Diego. “Most of that, the Trump administration has actively rolled back.”
In his first months in office, Mr. Trump announced that he would withdraw the United States from the 2015 Paris climate accord, under which nearly every country in the world had pledged to reduce emissions of planet-warming pollution.
Domestically, Mr. Trump directed Andrew Wheeler, the current head of the Environmental Protection Agency, to dismantle a suite of major climate change regulations put in place by the Obama administration, which had been designed to target pollution from the nation’s three largest sources of greenhouse emissions: coal-fired power plants, auto tailpipes and oil and gas drilling sites. Taken together, those rules represented the country’s first significant step toward reducing greenhouse gases, while putting the world’s largest economy at the forefront of the global effort to fight climate change.
Now they are in shambles.
In August, the E.P.A. completed the legal process of rolling back rules on methane, a powerful climate-warming gas emitted from leaks and flares in oil and gas wells. In April, it completed its rollback of the rules on tailpipe greenhouse pollution. And in June 2019, it replaced the Obama-era rule requiring coal plants to reduce emissions with a new rule devised to allow the plants to continue to release far more pollution.
If Mr. Biden is elected, he has vowed to rejoin the Paris agreement and reinstate those rules, while pushing to enact even stronger policies, spending up to $2 trillion to promote the development of renewable energy sources such as wind and solar.
But experts said it may take far more than that to rebuild the American climate change legacy — or its ability to persuade other governments to take similar action. That is a profound consequence, the experts said, because climate change is a global problem and cannot be meaningfully mitigated unless the world’s largest polluters all work in concert.
“The really big effect of what Trump has done is to send a message to the rest of the world that the United States is not credible on climate change,” said Mr. Victor of the University of California, San Diego. “The rest of the world is not going to know if we’re serious because we keep swinging back and forth.”
“Over the past 50 years, the effectiveness in creating international deals came from U.S. leadership,” he added. “And now nobody knows if we’re going to do that anymore.”
