Not only does defunding make the tools we've built with NOAA less valuable, but it also requires more *work* to get those same data out. 😮‍💨 Thank you to supporters, who help us move forward.

Monday was a tough day when we learned that NOAA was ending support for the Arctic Report Card. Since then we're received many expressions of solidarity, showing the value of the ARC to a wide audience. For that I am VERY grateful. #akwx #Arctic #Climate @climate.us @agu.org @drtwilamoon.bsky.social

My commentary on Marshall et al 2026's climate change rapid attribution study on severe Western U.S. snow drought, which developed during record-warm 2026 winter & has contributed to widespread drought & wildfire-related impacts since, is now out. [Thread] www.pnas.org/doi/10....

Cereal yields have increased in all regions, but Africa lags behind. Improved crop yields have allowed the world to feed billions more people while sparing forests and other land from agriculture. Global yields of cereal crops have tripled since 1961.

Widespread smoke and haze-filled skies remain over the Pacific Northwest as wildfires continue to burn in the region.

This is important - Honest Brokers (TM) and their echo chamber will often point to the decreasing global wildfire, but that reflects changing human land use practices. In temperate and boreal forests, climate's role is more clear. See this paper by Cunningham et al. www.nature.com/articles/s41...

Last week, lighting from thunderstorms ignited dozens of fires in Central Oregon. These wildfires have continued to burn for several days, scorching hundreds of thousands of acres of land in the region.

Long-range transport of smoke from late‑June wildfires in North America and Eurasia shows the 2026 boreal fire season is now picking up after a relatively calm start of the year.

The thing about solar geoengineering is that there is zero evidence that humankind is currently capable of the sort of global governance needed to deploy it responsibly and ethically, and if it were capable, it probably would not be needed.

“The research done at NCAR is an investment by every single tax-paying citizen in the United States, and it benefits all of us,” said UCS's @marc-alessi.bsky.social. “We are able to predict the weather days in advance, giving warning for hurricanes, extreme precipitation events, and droughts.”

It is hard to overstate how critical @ncar-ucar.bsky.social is to climate science in the US and around the world. It's the beating heart of our field. Generations of scientists have trained there, and almost everyone I know relies on deep collaborations with NCAR scientists. It's end is unthinkable.

Exclusive: The Trump administration is moving to dismantle the National Center for Atmospheric Research in Colorado, according to a senior White House official, taking aim at one of the world's leading climate research labs.

Here's our reporting on the proposed dismantling of the jewel of US atmospheric science, @ncar-ucar.bsky.social. The plan is to break NCAR apart and disburse some parts to other locations (like the research aircraft fleet) and eliminate others. www.nature.com/articles/d41... 🧪 #AGU25 #climate
