Trump seeks to end climate research at premier U.S. climate agency White House aims to end NOAA’s research office; NASA also targeted

The world knows about climate change mostly because of great American researchers, and that work has been largely centered at NOAA.
Trump and Musk are now shutting down that brilliant work. They are contemptible, short-sighted, and sold out
