Scientists Stand Firm on Climate Guide for Judges

The National Academies of Sciences just stood up for scientific integrity with the shortest, most powerful response imaginable.

Republican attorneys general from multiple states tried to force the prestigious science organization to delete a climate science chapter from a legal reference manual. The NAS response? Just two sentences saying the science stays put.

The controversy started when the Federal Judicial Center and NAS published the fourth edition of their Reference Manual on Scientific Evidence. This guide helps judges understand complex scientific topics when making legal decisions.

For the first time, the manual included a chapter on climate science. The addition made perfect sense since courts increasingly handle cases about environmental rules and fossil fuel companies.

But red-state attorneys general called the climate chapter "one-sided advocacy" and "judicial indoctrination." They demanded its removal, threatening the organization's federal funding. The Federal Judicial Center caved in February, deleting the chapter from their version.

The attorneys general then turned to the NAS itself. Their February 19 letter urged the Academies to follow suit, asking leading questions like "Why did you include climate science that is not based on balanced or sound science?"

The NAS gave them a deadline response that was masterfully brief. They explained they used the same rigorous peer review process for climate science as every other chapter. Then they added the kicker: "The manual, including the chapter on climate science, will continue to be available on the Academy's website."

Why This Inspires

This moment matters far beyond one chapter or one manual. When scientists refuse to let politics override facts, they protect the foundation of how our courts make fair decisions.

Other scientists rallied too. Authors of different manual chapters published an open letter warning that political interference with any scientific field threatens all of them. If politicians can pick and choose which established science gets taught, judges lose access to the best information available.

The real victory here is about process. The climate chapter cites the Intergovernmental Panel on Climate Change and experts who actually work on climate lawsuits. That's not advocacy, it's expertise.

By standing firm, the NAS sent a clear message: peer-reviewed science doesn't bend to political pressure. Their refusal protects not just climate science, but every field that helps courts serve justice.

The manual remains available to any judge who wants to understand the science behind the cases they decide.
