Please join the AGU Atmospheric Science ECC for a seminar titled "Measurements and Processes in the Stratosphere and Mesosphere'' on Wednesday, March 11 from 12:00-1:00pm Eastern Time. Two invited early career speakers will give their presentations, with time for Q&A afterward.
Congress rejected massive cuts to US science budgets for 2026, but much of the money still isn’t flowing to researchers.
The culprit? The White House Office of Management and Budget (OMB) is quietly slow-walking the release of funds. 🧵👇
Things I learned today - language in the Clean Air Act explicitly defines "air pollutant" to include anything with adverse effects on weather and climate

"Without the critical information NCAR provides, insurers would be significantly challenged when accurately pricing and
offering coverage, leading to significant affordability and availability challenges nationwide." - The American Academy of Actuaries actuary.org/wp-content/u... #SaveNCAR
Last December, weather and climate scientists sat down with us to tell us why they loved the National Center for Atmospheric Research, and why it benefits us all. Last night, the NSF began dismantling it. Listen to what they have to say, and why it's urgent that we #SaveNCAR wclivestream.com/act
My first sole-author paper is now published! 🎉🎉🎉
It's the culmination of a lot of thinking, so I hope you enjoy it.
Thanks to the friends, colleagues, and reviewers who helped make this happen 😊

This work was done during my NOAA Climate & Global Change postdoc at Columbia with Robert Pincus.
Many thanks to Robert, @lamont.columbia.edu, NOAA, and @ucar-cpaess.bsky.social for believing in me and supporting this work.
Will this persist in the future? This will have implications for trends in EEI and clear-sky climate feedbacks. Observations of radiative fluxes from CERES (and soon Libera) are essential for documenting these trends. We must continue to support continuous monitoring of Earth’s atmosphere.

2) At the same time, the SO aerosol increase amplifies (nearly 2x) the contribution of aerosols to the hemispheric albedo difference. We show that the atmospheric clear-sky contribution dominates the trend away from Earth's previously perfectly symmetric state. ☯️
Why does that matter? 1) It is offsetting reductions in NH anthropogenic aerosol decreases. This has led to negligible trends in global AOD. 📈📉
We show that increased wind speeds over the Southern Ocean have led to higher sea spray aerosol emissions. These higher aerosol burdens have caused larger atmospheric clear-sky albedo.

FY2026 NOAA/NASA/NSF budgets approved in Congress—a sharp rebuke to the White House (Project 2025) plans, with funding mostly maintained, safeguarding national labs, plus a 10% boost to NWS to "support full staffing" (anti-DOGE). No NCAR guarantee though balancedweather.substack.com?utm_source=n...
🚨 @aguscipolicy.bsky.social shares via email that the Senate may vote on a #SaveNCAR amendment TODAY 🚨
"By the end of this week, we may have a bill funding NSF that includes a safety net for NCAR."

Much like NCAR itself, the motions of the atmosphere that give rise to weather and climate phenomena are indifferent to political boundaries. The loss of this hub of scientific innovation and its computational resources will have immediate and dangerous consequences for all Americans.

Yes! Video coming soon, tba.
A strong statement from the Director of CNRS Earth and Space about the dismantling of the National Center for Atmospheric Research: "a pillar of atmospheric and climate research is being torn down"

#NCAR is great for both research and outreach.
While digging through my archives, I found this video I made of a small homemade tornado.
The #NCAR is one of the best places a climatologist can visit. I was lucky to be there for the 2018 CFMIP meeting.
What terrible news to hear that it might be dismantled...
#SaveNCAR
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.
Come to the Plenary room. We are doing interviews! @wclivestream.bsky.social
At @agu.org meeting? Share your story about @ncar-ucar.bsky.social! Our collective voices matter as we #saveNCAR!

The Trump administration said it will be dismantling the National Center for Atmospheric Research in Colorado, one of the world’s leading Earth science research institutions.
🚨 Calling all geoscientists 🚨 If you or anyone you know is attending #AGU25, please join us and spread the word to #SaveNCAR.

As someone not with NCAR, I use NCAR-based software everyday to help identify and track regions of excessive precipitation to help NWS forecasters protect lives and property. NCAR is extremely valuable and we need them.
NCAR is a unique & valuable asset - far more than a climate model, or observations, or technology, or training ground, or gathering space. It covers weather, space weather, data, climate, paleo-climate, and everything in-between. It's building is an icon, but it's iconic status goes far beyond that.
3 minutes on NCAR, what it does, and why it matters.
