Save NCAR from being dismantled today!

The Trump Administration has vowed to dissolve the center that provides critical extreme weather and climate data for our nation.

I look forward to the legally required, transparent peer review process required by the US Global Change Research Act and the Information Quality Act. I always thought they would try to do a NCA with Judith Curry, five old men and a LLM.

It’s the gold standard of US climate research. Contrarians could write the next one.

Researchers who have downplayed the threat of global warming have been asked to author the next National Climate Assessment.

The U.S. Is on the Verge of Meteorological Malpractice

The Trump administration says it will dismantle a premier climate center, while somehow keeping weather forecasting intact.

At an @agu.org Town Hall today, @ncar-ucar.bsky.social President Antonio Busalacchi spoke to #AGU25 attendees about what's at stake if NCAR is dismantled.

One attendee asked anyone who uses NCAR research to stand up. Almost everyone in the room stood.

In a large conference room full of people, the audience doesn't fit entirely in the frame of a photo. Nearly everyone pictured is standing.

Science has named the seemingly unstoppable growth of renewable energy worldwide as the 2025 Breakthrough of the Year.

Learn more about this year's #BOTY and other big advances in science: https://scim.ag/493Tpgx

Qianjiadong Reservoir in southern Hunan, China, produces a double harvest: solar energy and yellow carp. The solar farm produces up to 80 megawatts of power while the fish forage beneath the panels. With a massive scale-up of solar and wind at home and cheap exports of the technology, China is driving a worldwide surge of renewable energy—Science’s 2025 Breakthrough of the Year.

The administration dismantling NCAR is scientific vandalism, much like the Taliban demolishing cultural artifacts.

Fires, floods and other disasters are posing more risks to homes as the planet warms, but forecasting exactly which houses are most vulnerable — and might sell for less — has proved fraught.
