Biodiversity isn’t only protected in parks and policy documents, it is defended on the ground by communities and social movements, often at great personal risk.⁠

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.

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%.

In good news, your advocacy for science funding is paying off! Congress has just rejected the massive cuts to NASA's 2026 budget.

(Sadly, they didn't include a provision for saving @ncar-ucar.bsky.social but we use this win to keep fighting!)

Breaking News: The EPA will stop considering lives saved when setting pollution limits and instead calculate only the cost to businesses.
E.P.A. to Stop Considering Lives Saved by Limiting Air Pollution
In a reversal, the agency plans to calculate only the cost to industry when setting pollution limits, and not the monetary value of saving human lives, documents show.

It appears there is no withdraw process for @ipcc.bsky.social, participation in which is voluntary, free and open to all UN and WMO members. So the Trump administration’s supposed withdraw means less than their June firing of all the staff of the State Dept’s Office of Global Change

After the US admin cancelled the $B Climate + Weather Disaster dataset, @climatecentral.org hired the scientists who ran it and set it back up.

Now the 2025 numbers are in: it's 3rd highest year on record and highest year w/o land-falling hurricanes.

"Because the U.S. entered the UNFCCC with advice and consent of the Senate in 1992, it’s our legal view that it also must be exited using the same process in reciprocation... Letting this lawless move stand could shut the U.S. out of climate diplomacy forever"

“The changes permit as few as one outside review rather than the current minimum of three, end the routine use of expert panels to discuss those individual reviews, and give program managers greater authority to recommend which proposals should or should not be funded.”

We have upgraded our geomagnetic forecast today (12 November 2025) to the highest intensity level amid an ongoing solar storm.

Current predictions suggest that the activity will result in potentially the largest solar storm to hit our planet in over two decades.

This storm will be devastating for the island.
