We're excited to announce our session "From Weather Modification to Climate Intervention: Aerosol Impacts on Clouds Across Scales" at the AMS Annual Meeting in January 2027. Abstract submission is now open, abstracts are due by 11 August 2026. Submit today! annual.ametsoc.org/2027/program...

A plea to submit comments on the new proposed OMB rule that would put all U.S. science funding totally at the whim of political appointees, framed by a recap of the Weather and Climate Livestream a couple weeks ago. deepconvection.substack.com/p/speak-out-...

In this newsletter I outline important actions to take. 1. Submit a comment opposing the rule change. 2. Contact state legislators to ensure states are engaged with the impact at the state and local level. 3. Contact members of Congress. 4. Spread awareness. This rundown is a great source:

⏰ We're still looking for more speakers ⏰ Please sign-up (wclivestream.com/speak) to share your weather & climate science with the public. You'll give an accessible 10-min talk on your research to our live viewers. It's a great opportunity and a lot of fun! 🙌 wclivestream.com/2026-livestream

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. 🧵👇

White House stalls release of approved US science budgets

The US Congress rejected sweeping cuts to science agencies. But the NIH, the NSF and NASA have had their spending slowed.

Things I learned today - language in the Clean Air Act explicitly defines "air pollutant" to include anything with adverse effects on weather and climate www.govinfo.gov/content/pkg/...

"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 😊 agupubs.onlinelibrary.wiley.com/doi/10.1029/...

📢📢 New preprint alert! 📢📢 Radiation is a key piece of climate models, but comes with a trade-off: use an accurate scheme (which is difficult to understand), or a simple scheme (which is not very accurate)... Here I introduce a scheme which bridges this gap! arxiv.org/abs/2508.09353

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).

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.

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. #SaveNCAR

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" @cnrs-insu.bsky.social @cnrs.fr @ncar-ucar.bsky.social

#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
