250 years of burning fossil fuels fuelled a record shattering humid heatwave in Eastern North America for the 250th anniversary celebrations on 4th of July. Turning any outdoor activities into a dangerous health risk. - @wwattribution.bsky.social www.worldweatherattribution.org/fossil-fuels...

As someone who studied and worked in the US before moving back to India, the idea of dismantling NCAR just doesn’t compute! I used NCAR data for my PhD and my students use the CESM. The impact of NCAR is global. We would love to have an NCAR in India but building it is not as easy as destroying it.

This is the most astonishing graph of what the Trump regime has done to US science. They have destroyed the federal science workforce across the board. The negative impacts on Americans will be felt for generations, and the US might never be the same again. www.nature.com/immersive/d4...
This line graph illustrates the percentage change in agency staff levels from the previous year for nine major U.S. federal scientific and health organizations between the fiscal years 2016 and 2025. The agencies tracked include the CDC, Department of Energy, EPA, FDA, NASA, NIH, NIST, NOAA, and NSF. For the majority of the timeline between 2016 and 2023, the agencies show relatively stable fluctuations, generally staying within a range of +5% to -5% change per year. However, there is a dramatic and uniform plummet starting in the 2024–25 period. Every agency depicted shows a sharp downward trajectory, with staffing losses ranging from approximately -15% to over -25%. The Environmental Protection Agency (EPA) shows the most significant decline, dropping to roughly -26%, while the National Institute of Standards and Technology (NIST) shows the least severe but still substantial drop at approximately -15%.
