We're just getting started. 🔮

This release sets the stage for a fully coupled, differentiable Earth System Model. We are actively developing this next phase with colleagues at U Copenhagen, Columbia, DLR, and AI2.

Watch this space...

Bridging Physics & AI in Climate Modeling 🌍🤖

Introducing JCM v1.0: A fully differentiable, intermediate-complexity atmospheric model built in Python/JAX.

Training hybrid models is hard because legacy code lacks gradients. JCM solves this.

Ever wondered whether there's a principled way to calibrate all those parameters controlling climate models? In our new paper we show how to calibrate climate model parameterizations using ideas from Bayesian experimental design: doi.org/10.1088/3049... . (1/N)

Just finished @hannahritchie.bsky.social's fantastic book "Not the End of the World" which nicely articulates the things we should, and should not, be worrying about when it comes to sustainability. It's a refreshing and empowering take backed by the latest data. Definitely recommend!

Excited to be kicking off another season of "AI and Climate Science" webinars as part of the UN 'AI for Good' Discovery series this quarter with a talk from Chris Bretherton reflecting on 'AI for climate modeling from present to future'.

In the face of steep funding cuts for climate and weather research and forecasting, scientists have found a new way of engaging the public: livestreamed presentations.

Industrial pollution in colder regions increases snowfall and reduces cloud cover, potentially boosting global warming by reducing the sunlight that clouds reflect back into space, according to a new study from Scripps Oceanography researcher Duncan Watson-Parris. (@dwatsonparris.bsky.social)
Industrial Pollution Can Increase Snowfall and Reduce Cloud Cover
