Federal Judiciary and Climate Litigation

The Federal Judicial Center omitted the "Reference Guide on Climate Science" from the 4th edition of its Reference Manual on Scientific Evidence on Feb. 6, 2026, shortening the PDF from 1,682 to 1,662 pages and adding an appendix footnote noting the omission. The change followed Fox News Digital reporting and pressure from 22 state attorneys general — including West Virginia’s JB McCuskey and Nebraska’s Mike Hilgers, who claimed credit — and was hailed by conservative critics such as Judicial Watch as a corrective to alleged partisan indoctrination and a spur for an expanded House probe.
