The Republican attorneys general whose complaints led to the deletion of a judicial manual’s climate science chapter are asking one of the nation’s leading science bodies to yank that chapter from its website.

In a letter Thursday to the National Academies of Sciences, Engineering and Medicine, the coalition of 21 attorneys general say the scientific body should immediately remove the chapter “to stop any continued claims of political pamphleteering.”

The move comes two weeks after the Federal Judicial Center — the education and research arm of the federal court system — pulled the climate chapter from the manual following complaints it was biased against the fossil fuel industry.

The judicial reference manual was published in December 2025 by the judicial center and the National Academies. It is aimed at assisting judges handling cases with complex scientific and technical evidence. The fourth edition included new guides on eyewitness identification, computer science and artificial intelligence, as well as climate science.
