Dismembering the program was outlined in Project 2025 as a way to elevate the “benefits” of climate change when fighting regulations in court.

The Trump administration is dismantling a 35-year-old effort to track global climate change that was used to shape regulations and policies across the government.

Federal employees at the U.S. Global Change Research Program were removed from their positions Tuesday, and a government contract with ICF International, which has supported the National Climate Assessment for years, was severed, according to two former officials who were granted anonymity to avoid reprisals.

The move marks a key step by the administration to undermine federal climate research as it rolls back environmental regulations and promotes additional fossil fuel production.

The program was established by Congress in 1990 and signed into law by President George H.W. Bush. In addition to climate science, it focused on land productivity, water resources, fisheries, ecosystems and the atmosphere. Its most visible product was the National Climate Assessment, a Congress-mandated report that comes out every four years and is used to help shape environmental rules, legislation and infrastructure projects.
