WASHINGTON, D.C. — US experts on Tuesday denounced a Trump administration climate report for reviving the tobacco-industry's tactics to sow doubt around scientific consensus.

In a 440-page rebuttal, 85 scientists accused the government of relying on a handful of contrarians who drew on discredited studies, misrepresented evidence, and bypassed peer review to reach pre-determined conclusions.

The administration's 150-page report, released on the Department of Energy's website in late July, was intended to support its proposal to overturn the 2009 "Endangerment Finding" -- the legal basis for numerous federal regulations of greenhouse gases.

"This report makes a mockery of science," said Andrew Dessler, a climate scientist at Texas A&M University and a co-author of the rebuttal.

"It relies on ideas that were rejected long ago, supported by misrepresentations of the body of scientific knowledge, omissions of important facts, arm waving, anecdotes, and confirmation bias."

Entitled "A Critical Review of Impacts of Greenhouse Gas Emissions on the US Climate," the DOE document made a series of startling and at times contradictory claims.

These include that extreme weather events linked to emissions are not increasing, US temperatures are not rising, higher atmospheric carbon dioxide would boost agriculture, and solar activity could explain warming trends.

'Zombie arguments' 

The rebuttal marshals experts from multiple disciplines to challenge each assertion.

"Just as the tobacco industry funded scientists to question the harms of smoking, the fossil fuel industry engaged in a coordinated campaign throughout the 1990's to fund scientists willing to argue that it was the Sun, and not humans, causing the climate change observed up to that point," said Ted Amur, a climate scientist at Aon Impact Forecasting, adding he was alarmed to see "zombie arguments" brought back.

The DOE report claimed that the "Dust Bowl" years of 1930–1936 -- among the nation's hottest summers -- disproved the reality of human-caused warming. But the counter report said this was deeply misleading, since poor land management at the time had turned the Great Plains into a desert-like wasteland that amplified the heat.

On agriculture, the rebuttal notes that while elevated carbon dioxide can sometimes spur yields in isolation, rising heat and shifting rainfall patterns are expected to cause overall declines.

The DOE report also downplays the threat of ocean acidification, claiming "life in the oceans evolved when the oceans were mildly acidic" billions of years ago. But the rebuttal counters this is "irrelevant" since complex life was not present during Earth's early history.

"US coral reefs alone provide an estimated .8 billion in coastal protection from storms and floods annually," she said.

Since returning to office in January, President Donald Trump has gone far beyond the pro-fossil fuel agenda of his first term. Republicans recently passed the "Big Beautiful Bill," gutting clean energy tax credits and opening sensitive areas to drilling.

He has also withdrawn the United States from the Paris Agreement and is pressing his fossil fuel agenda abroad --requiring the EU to buy more US liquefied natural gas in a trade deal and pressuring the World Bank to scale back its climate focus, among other actions.
