New AMS Statement: Dismantling NSF’s National Center for Atmospheric Research would weaken U.S. leadership in weather, water, and climate science, putting public safety at risk.

For more than 60 years, NSF NCAR has improved forecasts and early warnings that save lives. More: https://bit.ly/4q6eChn

Check out this time-lapse video of waves eroding an ice front from an experiment conducted in our cryogenic wave tank at the University of Wisconsin-Madison. The tank is housed in a walk-in freezer, and the waves are precisely controlled. This video captures about an hour of wave erosion.

It's even worse than removing the grant funding for university research (in groups like mine at UC Irvine). NOAA labs and cooperative institutes collect the climate data we use, develop the predictive weather and climate models, and train the students we hire.

This demolishes U.S. climate research.

Any time a fluid under gravity has areas of differing density, it convects. We're used to thinking of this in terms of temperature -- "hot air rises" -- but temperature isn't the only source of convection.

White House Plan Calls for NOAA Research Programs to Be Dismantled (Gift Article) A Trump administration budget proposal would essentially eliminate one of the world’s foremost Earth sciences research operations.

Critical yet often overlooked is that NOAA's Oceanic and Atmospheric Research maintains vital long-term monitoring programs like the CO₂ Keeling Curve that, while essential, often struggle for funding from agencies like NSF that prioritize hypothesis-driven research over sustained observation.

Excited to share our new paper in @pnas.org doi.org/10.1073/pnas...! Ice cubes often appear cloudy because, as water freezes, air bubbles get trapped and scatter light. But how does freezing rate affect the shape of the bubbles?

I’ve been teaching our first-year undergrads this week about weather forecasting — how it is a tremendous, life-saving human achievement that is so important to modern society, underpinned by openness & a desire to cooperate…
