Climate change communicator. Focus on what scientist and economist wonks tell us, and the controversies, because so many of us oppose at least one major solution.

Just did some number crunching using latest (Oct 1) ECMWF seasonal data, and I must say that I've never seen such high predictive confidence in a very wet California winter. This is a truly extraordinary forecast amid a record-strength El Niño event. [Thread: please read to end.]
Model-relative sea surface temperature anomalies for November 2026–January 2027. The supplied grid is displayed without added smoothing or coastal filling. Beige marks land and gray marks missing ocean values. The main colour scale spans -2 to +10°F, with white at zero. Hot pink marks anomalies above +10°F.

@rarohde.bsky.social, @climateofgavin.bsky.social, other WG1 folks: AR6: contribution from ice sheets doubled??? from 2006-2018 compared to 1993-2006. Today, what is contribution from ice sheets? What is trajectory? USGCRP when I started reading: IS as important as thermal in 1,000 y.

Let's talk about the weather and climate changes that preceded the Nepali glacier collapse and landslide. It's well known that Nepal is warming, but we can do better and estimate the changes at the 5200m elevation site where the mass of ice and rock ultimately broke loose. A thread. 🧵🧪

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%.
