In 2025, the Trump administration initiated an unprecedented rollback of federal climate science infrastructure, targeting core research institutions, observational systems, and legal frameworks that have underpinned U.S. and global climate understanding for decades. The most striking move came on December 16, 2025, with the announcement that the National Center for Atmospheric Research (NCAR) would be broken up—marking the first time a major national climate modeling center has been intentionally dismantled by executive action.
Administration officials framed these actions not as budgetary or structural reforms, but as an ideological purge of what they described as politically motivated science.
Official Rhetoric Targeting Climate Science
Senior administration figures used explicitly political and anti-scientific language to justify the dismantling of climate research institutions:
- “Climate Alarmism”: White House Budget Director Russell Vought labeled NCAR “one of the largest sources of climate alarmism in the country,” asserting that its research exaggerated risks.
- “Left-wing Climate Lunacy”: Other senior officials described NCAR as a “premier research stronghold for left-wing climate lunacy.”
- “Green New Scam”: The administration argued that dismantling NCAR was necessary to eliminate what it called “Green New Scam research activities.”
- “Con Job” and “Hoax”: These attacks mirrored President Trump’s broader rhetoric throughout 2025, including his September address to the United Nations in which he described climate change as “the greatest con job ever perpetrated on the world” and “the biggest hoax ever.”
This language represents a departure from prior policy disagreements over climate mitigation and instead signals a direct rejection of the scientific enterprise itself.
Key Climate Science Dismantling Actions (2025)
National Center for Atmospheric Research (NCAR)
NCAR, headquartered in Boulder, Colorado, has been a global leader in climate and atmospheric modeling for more than six decades. In December 2025, the administration announced plans to “break up” the institution. While some operational weather forecasting functions may be reassigned, NCAR’s core climate modeling, paleoclimate research, and Earth system science programs face immediate dissolution. Researchers warn that the loss of NCAR’s integrated modeling capacity will severely impair long-term climate projection and extreme-weather attribution.
National Oceanic and Atmospheric Administration (NOAA)
Following policy guidance from Project 2025, the administration proposed cutting NOAA’s budget by nearly 25%, reducing funding from approximately $6.1 billion to $4.5 billion. Proposed actions include:
- Eliminating the Office of Oceanic and Atmospheric Research (OAR), NOAA’s primary climate research arm.
- Permanently closing more than two dozen facilities, including:
- The National Severe Storms Laboratory
- The Mauna Loa Observatory, which has maintained the world’s longest continuous CO₂ record since the 1950s.
- Ending the public tracking of “billion-dollar disaster” statistics, a dataset widely used by insurers, emergency planners, and economists.
NASA Earth Science Division
Budget proposals seek to reduce NASA’s Earth science funding by roughly 50%, lowering it to approximately $1 billion. These cuts would cancel or indefinitely delay next-generation satellite missions designed to monitor sea-level rise, ice-sheet dynamics, atmospheric aerosols, and ocean heat content—key indicators of accelerating climate change.
U.S. Global Change Research Program (USGCRP)
The administration has restructured the USGCRP, which coordinates climate research across 13 federal agencies. Several congressionally mandated climate assessment reports have been removed from public access, disrupting continuity in national climate risk assessment and long-term planning.
Policy and Regulatory Rollbacks
These institutional changes are accompanied by sweeping regulatory reversals:
- Paris Agreement: On January 22, 2025, President Trump formally withdrew the United States from the Paris Climate Accord for a second time.
- EPA Endangerment Finding: The Environmental Protection Agency is moving to rescind the 2009 Endangerment Finding, the legal basis for regulating greenhouse gases under the Clean Air Act.
- Inflation Reduction Act (IRA): Major provisions of the IRA have been dismantled, halting billions in clean energy tax credits and canceling approximately $8 billion in climate-related funding previously allocated to 16 states.
Impacts on the Scientific Workforce
By December 2025, more than 200,000 civil servants had exited the federal workforce, including thousands of scientists and technical staff from NASA, NOAA, and the National Science Foundation. Climate researchers warn that the loss of institutional memory, observational continuity, and modeling capacity will take decades to rebuild—if rebuilding remains politically possible.
Experts across disciplines caution that dismantling these institutions “undermines the factual backbone” of climate risk assessment, leaving the United States—and the global community—less prepared for accelerating extreme weather, infrastructure failures, food system shocks, and economic instability.
A Structural Break in Climate Governance
Taken together, these actions represent not a routine policy shift but a structural rupture in U.S. climate governance. For the first time, federal climate science infrastructure is being actively dismantled while climate-driven disasters are accelerating in frequency, intensity, and cost. The long-term consequences extend beyond environmental policy, affecting national security, economic stability, public health, and global scientific cooperation.
The choice is no longer whether change is coming, but whether we act quickly enough to remain biologically capable of surviving it.
* Our probabilistic, ensemble-based climate model — which incorporates complex socio-economic and ecological feedback loops within a dynamic, nonlinear system — projects that global temperatures are becoming unsustainable this century. This far exceeds earlier estimates of a 4°C rise over the next thousand years, highlighting a dramatic acceleration in global warming. We are now entering a phase of compound, cascading collapse, where climate, ecological, and societal systems destabilize through interlinked, self-reinforcing feedback loops.
We examine how human activities — such as deforestation, fossil fuel combustion, mass consumption, industrial agriculture, and land development — interact with ecological processes like thermal energy redistribution, carbon cycling, hydrological flow, biodiversity loss, and the spread of disease vectors. These interactions do not follow linear cause-and-effect patterns. Instead, they form complex, self-reinforcing feedback loops that can trigger rapid, system-wide transformations — often abruptly and without warning. Grasping these dynamics is crucial for accurately assessing global risks and developing effective strategies for long-term survival.
What Can I Do?
The single most important action you can take to help address the climate crisis is simple: stop burning fossil fuels. There are numerous actions you can take to contribute to saving the planet. Each person bears the responsibility to minimize pollution, discontinue the use of fossil fuels, reduce consumption, and foster a culture of love and care. The Butterfly Effect illustrates that a small change in one area can lead to significant alterations in conditions anywhere on the globe. Hence, the frequently heard statement that a fluttering butterfly in China can cause a hurricane in the Atlantic. Be a butterfly and affect the world.
Tipping points and feedback loops drive the acceleration of climate change. When one tipping point is breached and triggers others, the cascading collapse is known as the Domino Effect.
