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.
