The Trump administration told researchers it was “releasing” them from their roles. It puts the future of the assessment, which is required by Congress, in doubt.

The Trump administration has dismissed the hundreds of scientists and experts who had been compiling the federal government’s flagship report on how global warming is affecting the country.

The move puts the future of the report, which is required by Congress and is known as the National Climate Assessment, into serious jeopardy, experts said.

Since 2000, the federal government has published a comprehensive look every few years at how rising temperatures will affect human health, agriculture, fisheries, water supplies, transportation, energy production and other aspects of the U.S. economy. The last climate assessment came out in 2023 and is used by state and local governments as well as private companies to help prepare for the effects of heat waves, floods, droughts and other climate-related calamities.

On Monday, researchers around the country who had begun work on the sixth national climate assessment, planned for early 2028, received an email informing them that the scope of the report “is currently being re-evaluated” and that all contributors were being dismissed.

“We are now releasing all current assessment participants from their roles,” the email said. “As plans develop for the assessment, there may be future opportunities to contribute or engage. Thank you for your service.”

For some of the authors, that appeared to be a fatal blow to the next report.

“This is as close as it gets to a termination of the assessment,” said Jesse Keenan, a professor at Tulane University who specializes in climate adaptation and was a co-author on the last climate assessment. “If you get rid of all the people involved, nothing’s moving forward.”
