Spherical DYffusion: AI Accelerates Century-Scale Climate Forecasting from Months to Hours

April 15, 2026 · From the archive, written in the Professor's voice before our October 2026 redesign from today.ucsd.edu

What happened

UC San Diego and the Allen Institute for AI developed Spherical DYffusion, a hybrid model combining generative AI with physics-based data to simulate 100 years of climate patterns in just 25 hours. This method leverages diffusion models adapted to spherical data domains, vastly accelerating climate projection without compromising scientific rigor.

Why it matters

This innovation exemplifies how integrating domain knowledge with generative AI can overcome computational bottlenecks in complex simulations. It encourages practitioners to blend physics-based modeling with AI to achieve scalable, fast, and reliable forecasts, thus redefining workflows in climate science and beyond.

Who's doing it

The research teams at UC San Diego and the Allen Institute for AI have successfully demonstrated this approach, enabling faster climate model iteration and potentially informing policy with more timely data.

Try it

  1. Access the Spherical DYffusion framework or similar diffusion model implementations, starting from repositories linked in the UCSD announcement.
  2. Prepare your climate or spherical geospatial dataset compatible with the model's requirements.
  3. Run the model for accelerated climate projection, validating outputs against traditional simulations. For further information, visit https://today.ucsd.edu/story/nine-breakthroughs-made-possible-by-ai.
