🚨The most important graph in the world has another year of data, and it doesn't look good!🚨

NASA CERES satellites measure how much sunlight Earth absorbs and how much heat is radiated back to space.

The difference is heat accumulation, which has more than tripled!

OKAY BIG ONE FOR YA

NEW report out today: I dig deep into how big tech has been muddling tech types and overstating evidence to claim "AI" will make global emissions drop like a stone....

Not only will it not, it seems to be verifiably doing the opposite!!

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.

NEW STUDY: Climate change is fueling deadly fires that threaten some of the world’s oldest living things: the ancient Alerce trees of Patagonia, which can live for over 3,000 years.

Our analysis shows that human-induced warming is making weather conditions more conducive to fire. 1/5

I wrote this song on Saturday, recorded it yesterday and released it to you today in response to the state terror being visited on the city of Minneapolis. It’s dedicated to the people of Minneapolis, our innocent immigrant neighbors and in memory of Alex Pretti and Renee Good.

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%.

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.

How Did the C.I.A. Lose a Nuclear Device in the Himalayas? (Gift Article) A plutonium-packed generator disappeared on one of the world’s highest mountains in a covert mission that the U.S. will not talk about.

Oh man, what a story of a plutonium generator lost at Nanda Devi!
By putting an unmanned station on top of the Himalayas, the C.I.A. hoped to pluck radio signals from high-altitude missiles launched from China.

A climate scientist reflects on 30 years fighting the 'forces of unreason' Thirty years ago, the IPCC agreed on a historic finding: β€œThe balance of evidence suggests a discernible human influence on global climate.”

I had the great privilege of working with Ben at the Livermore Labs and be a part of the AR6 chapter that featured the β€œunequivocal” finding - a vast leap from the β€œdiscernible human influence”. If we have seen further it is by standing on the shoulders of giants ..

DOEresponseSite On July 29, 2025, the Department of Energy (DOE) published a report from its Climate Working Group (CWG). This report features prominently in the EPA's reconsideration of its 2009 Endangerment Finding. In response, over 85 scientists have come together to write a comprehensive review, which is

That event still remains my single most important influence in the research journey I have undertaken. There are many more human failures waiting to be shown up by climate change if we don’t get it together.

Hurricane Katrina in photos, 20 years after the "slow-motion catastrophe" While Hurricane Katrina's toll didn't become clear for days, the storm ultimately led to nearly 1,400 deaths, according to the National Hurricane Center.

New Orleans has been on my mind these last couple of days- more than usual. Hurricane Katrina was 20 years ago and the city that I still consider my spiritual home had been devastated.
