Trump Administration Places Climate-Science Skeptic at Helm of National Climate Assessment

Core Appointment
On July 10, 2026, reports confirmed that the Trump administration has installed former University of Alabama geochemist Matthew M. Wielicki as director of the U.S. Global Change Research Program (USGCRP). The USGCRP is the federal agency responsible for drafting the National Climate Assessment, a congressionally mandated report that evaluates how climate change impacts U.S. infrastructure, ecosystems, and the economy. Wielicki, who describes himself as a “professor in exile,” has no formal training in climate science and is known for publicly questioning the consensus on anthropogenic warming.
Background & Context
The USGCRP was effectively defunded during President Donald Trump’s first year in office, and hundreds of scientists working on the next assessment were dismissed. The most recent assessment, released in 2023, warned that human-caused warming was intensifying western wildfires, Great Plains droughts, and coast-to-coast heat waves. Since taking office, President Trump has repeatedly labeled climate change a “hoax,” withdrawn the United States from the Paris Agreement, and rescinded an Obama-era EPA rule that would have regulated greenhouse-gas emissions. White House budget director Russell T. Vought has called for an overhaul of the USGCRP, arguing its findings have been used to justify environmental lawsuits that constrain government actions.
Key Figures & Groups
- Matthew M. Wielicki – former geochemist, self-identified climate-science critic, frequent commentator on conservative media.
- President Donald Trump – former president, long-time climate-change denier.
- White House spokesperson – issued the administration’s official response to the appointment.
- Dr. Carlos Martinez – senior climate scientist, Union of Concerned Scientists.
- Ryan Katz-Rosene – professor, School of Political Studies, University of Ottawa.
Official Statements & Responses
The White House asserted that the administration is “committed to using the best scientific information to inform public policy” and that the USGCRP had been “used as a vehicle for political agendas instead of sound science.” The statement added that the agency would be “restored” to fulfill its legal mandate. President Trump, posting on Truth Social, claimed that climate activism has been weaponized by Democrats to “push horrible Energy Polices” and promised an administration “based on TRUTH, SCIENCE, and FACT.”
Criticism & Opposition
Climate experts warn that Wielicki’s leadership threatens the credibility of the National Climate Assessment. Dr. Carlos Martinez described the appointment as placing “the National Climate Assessment under the auspices of an utterly unqualified climate science denier,” risking the integrity of a key scientific resource. Ryan Katz-Rosene likened the move to “putting a Flat Earther in charge of NASA,” emphasizing the potential for politicization of climate data.
Data & Statistics
- The 2023 National Climate Assessment linked rising temperatures to increased frequency of wildfires, severe droughts, and widespread heat waves.
- The World Meteorological Organization reports that the past 11 years have been the warmest on record.
- United Nations assessments indicate that an overwhelming majority of climate scientists attribute recent warming primarily to human activities.
Conflicting Reports & Gaps
Sources differ on Wielicki’s qualifications: while the administration highlights his “scientific background,” critics note his lack of formal climate-science training and a history of dismissing peer-reviewed research as “stamp collecting.” No detailed plan has been released outlining how the reopened USGCRP will conduct the forthcoming assessment, leaving uncertainty about methodological rigor and public-input processes.
Verbatim Quotes
- “the science is not settled on climate change” — Matthew M. Wielicki, X post
- “For far too long Climate Activism has been used by Dumocrats to scare Americans, push horrible Energy Polices, and fund BILLIONS into their bogus research programs,” — Donald Trump, Truth Social (May 2026)
- “The Trump Administration is committed to using the best scientific information to inform public policy. For too long, the USGCRP has been used as a vehicle for political agendas instead of sound science. We look forward to restoring the USGCRP and ensuring it fulfills its legal mandate.” — White House spokesperson
- “Reconstituting the UCSGCRP only to place the National Climate Assessment under the auspices of an utterly unqualified climate science denier,” — Carlos Martinez, Union of Concerned Scientists
- “sadly… is not a joke,” and that it was “like putting a Flat Earther in charge of NASA.” — Ryan Katz-Rosene, University of Ottawa
The appointment marks a pivotal shift in how the federal government will evaluate and communicate climate risks, raising questions about scientific independence, policy direction, and the future reliability of the nation’s flagship climate report.
