Donald Trump urges review of judges' climate‑science manual

U.S. President Donald Trump posted on Truth Social on July 19, calling for a review of the Federal Judicial Center’s Reference Manual for Scientific Evidence, specifically the chapter dealing with climate change. He described the manual’s content as "discredited" and claimed it caused "huge losses" for the country, ordering "Federal Suspension and Debarment Officials" to examine the conduct, though it was unclear what conduct he meant.

The White House did not immediately respond. Earlier in the year, the federal judiciary removed a climate‑change chapter after Republican state attorneys general argued it was biased against fossil‑fuel interests. The manual, used by judges to assess scientific testimony, was authored by Jessica Wentz and Radley Horton of Columbia Law School and produced in partnership with the National Academies of Sciences, Engineering, and Medicine. Multiple Reuters reports covered Trump’s statement and the background of the manual’s revision.
