NSF has put out a “Dear Colleague Letter” asking how to dismantle NCAR, the premier public atmospheric sciences center in the US. We must reject the premise. As a dedicated center bringing together scientists across disciplines and across the world, NCAR science has saved lives for over 65 years.

🤯🤯🤯 Full-on denial of reality. State capture by the fossil fuel lobby. The US descends into a banana republic. It would almost be funny if the consequences wouldn’t be so dire for billions of humans, if the courts don’t stop this folly soon. www.scientificamerican.com/article/epa-...

One major rule anchored U.S. climate policy. The EPA just threw it out

Fearing that educated judges might rule on climate cases, Republican Attorneys General successfully bullied the The Federal Judicial Center (the education & research arm of the federal court system) into removing a chapter summarizing climate science from their scientific judicial reference manual.

In a letter Friday to West Virginia Attorney General JB McCuskey, the Federal Judicial Center said it had "omitted" the climate science chapter from its latest
Reference Manual on Scientific Evidence. The removal marks a significant victory for Republican efforts to thwart a raft of climate lawsuits that the fossil fuel industry has warned could cost it billions of dollars. On Friday, the Republican Attorneys General Association congratulated its members on X, writing that the "Federal Judicial Center has announced they are removing ridiculous WOKE climate science from judicial
manuals."
