Judicial research center cuts climate section from judges' manual after Fox News Digital report

The Federal Judicial Center regularly publishes its Reference Manual on Scientific Evidence, and the climate policy chapter of its fourth edition, released on Dec. 31, included several pages of content critics said had been gleaned from left-wing climate advocates and were indoctrinating judges rather than educating them.

Late Friday, federal Judge Robin Rosenberg - the Obama-appointed jurist who leads the center at the Thurgood Marshall Building in Washington - wrote to West Virginia Attorney General JB McCuskey alerting him that the climate policy chapter has been removed from the guide.

McCuskey and Nebraska Attorney General Mike Hilgers recently led the charge to get the House Judiciary Committee to expand its probe on climate-related policy influence on federal judges to include the contents of the manual.

The approximately 1,600-page guide was released at the beginning of the year and included several citations and footnotes to climate change activists and proponents, including climatologist Michael Mann and environmental law expert Jessica Wentz.

A footnote in the appendix also indicated that "The FJC omitted 'Reference Guide on Climate Science' on 2/6/2026."

In a statement, McCuskey said his office led the charge in calling for the FJC to withdraw "an inappropriate new addition to the Reference Manual on Scientific Evidence that deals with 'climate science'."

"Huge win," Hilgers reacted on social media. "Proud to work on this with [McCuskey] and our Republican AGs."
