The record does not show one self-executing Trump order that completed every climate and health research cut. It shows three mechanisms: an executive review order, proposed EPA and NOAA budget cuts, and administrative actions affecting HHS and NIH grants. That distinction matters. A presidential budget request proposes funding levels to Congress; it does not itself change appropriations.

The executive order that set the direction
President Trump's january 20, 2025 energy order directed agencies to pause Inflation Reduction Act and infrastructure-law disbursements while reviewing them. It also required EPA to recommend whether its 2009 greenhouse-gas endangerment finding should remain in place.
The order established policy direction, but it did not enact the later EPA and NOAA funding proposals. Those appeared in separate FY2026 budget documents and required congressional action.
What the EPA budget requested
The white house Office of Management and Budget proposed cutting EPA's Office of research and Development by $235 million. It would leave $281 million for research described as necessary for EPA's statutory responsibilities while ending climate-research grants characterized as unauthorized. The request also proposed eliminating the $100 million Atmospheric Protection Program.
OMB described that program as an overreach connected to climate regulation in its FY2026 discretionary budget request. These were targeted choices, not the proposed elimination of every EPA research activity. The administration sought to retain specified core research while removing climate grants and an atmospheric program.
NOAA faced the broader research proposal
NOAA's proposal went further institutionally. Its FY2026 submission requested zero dollars and zero positions for the Office of Oceanic and Atmospheric Research, known as OAR, and proposed eliminating it as a NOAA line office. Selected weather and ocean functions would move to the National Weather Service and National Ocean Service.
However, the proposal would end funding for climate, weather, and ocean laboratories and cooperative institutes, as detailed in NOAA's congressional budget submission. Funding for Regional Climate Data and Information and Climate Competitive Research would also end. The affected research network included federal laboratories, cooperative institutes, and outside climate researchers.
HHS restructuring and NIH grant directives
HHS announced on March 27, 2025 that its restructuring would eliminate about 10,000 full-time jobs. Combined with other actions, the department said its workforce would fall from 82,000 to 62,000 employees. Environmental-health functions would move into a new Administration for a Healthy America. NIH and HHS also adopted directives listing "Climate Change" among research activities NIH no longer supported.
The First Circuit upheld an injunction against those policy directives while litigation continued. The Supreme Court later addressed the remedy and forum for terminated grants, not a final resolution of every underlying issue. It stayed the order vacating NIH grant terminations, reasoning that claims seeking promised grant money likely belong in the Court of Federal Claims. The legality of the terminations and restoration of affected awards therefore remained unresolved.
How to tell a proposal from an operative cut
Readers should not treat every amount in these documents as money already removed. The EPA and NOAA figures were presidential FY2026 requests, and Congress controls appropriations. For an affected researcher, institution, or grant recipient, the key questions are: Before describing an EPA or NOAA proposal as a completed cut, verify the enacted appropriation or an agency action affecting the specific program.
- Was funding merely targeted in a budget request, or did the agency issue a termination notice?
- Does the dispute challenge a policy directive or seek payment of promised grant money?
- What award document, termination explanation, and payment record establish the claimed loss?
- Did Congress later enact the requested funding level?
