This week, LEAP REU students Troy Stephens + Katherine Frields and LEAP Momentum Fellow Giorgia Nicolaou presented "AI Generation of Thermodynamic Histories From Ice Crystal Images" at the 2025 @columbiauniversity.bsky.social Pathways Program (CUPP) Research Symposium!

What are geoengineering and cloud seeding, and what are their implications for future climate mitigation strategies? @karadlamb.bsky.social—research scientist at @columbiauniversity.bsky.social studying aerosols, cloud physics, machine learning—explains: news.climate.columbia.edu/2025/07/17/g...

This iconic NASA office changed climate science forever. DOGE plans to kill it

The NYC space is where the term ‘black hole’ was coined and where James Hansen became famous for his warnings about climate change.

Kyleen Liao did stellar work with @karadlamb.bsky.social, Pierre Gentine, and me a while ago on simulating PM2.5 emissions from California wildfires using graph neural networks (GNNs). Her paper with cool new model validation results is out now: www.cambridge.org/core/journal...

Perseverance Views Drifting Clouds - NASA Science

NASA's Perseverance Mars rover used one of its navigation cameras to take a series of images of drifting clouds just before sunrise on March 18, 2023, the 738th Martian day, or sol, of the mission.
