President Donald Trump ordered a formal review of a federal judiciary manual on climate science, leading to its withdrawal by the Federal Judicial Center. The move marks an unprecedented intervention by the executive branch into the scientific resources available to U.S. judges.
The manual, published by the National Academies of Sciences, Engineering, and Medicine, was first released in 2023 and updated in 2026. It was designed to help federal judges understand climate science in litigation involving property rights, emissions, and disaster cases. The climate chapter became a target.
Trump called the manual “biased against energy independence” and “junk science.” His executive order demanded a review. The Federal Judicial Center complied, withdrawing the document from official use.
What was in the manual? It summarized peer-reviewed climate science. It explained key concepts like greenhouse gas attribution and sea-level rise modeling. The National Academies stated the work was developed by independent experts and underwent rigorous peer review.
The core conflict is clear: who controls what judges read? The National Academies operate independently from the executive branch. Trump’s intervention directly challenges that separation. The Hill reported that legal scholars see this as a test of judicial independence.
Reactions have been sharp. Scientists defended the manual. Democratic senators accused Trump of “censoring science.” Conservative groups praised the move, calling it a check on “activist science.” The National Academies issued a statement defending the manual’s integrity. The Federal Judicial Center did not comment further.
The long-term impact remains uncertain. Judges may now rely on less authoritative sources. Scientific advisory bodies could face a “chilling effect.” Legislation to protect judicial access to independent science is a possibility. This case fits a broader pattern of Trump challenging institutional expertise.
The bench is now a battleground. The Trump administration‘s intervention in the National Academies’ manual is a landmark test. Can science remain apolitical in the courtroom? Court challenges or congressional hearings are likely. The story is far from over.
