Spherical Diffusion Model Accelerates Century-Scale Climate Projections from Months to Hours

April 7, 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 AI-physics model that compresses 100 years of climate simulation into 25 hours. It uses generative AI combined with physics-driven data to produce accurate long-term climate forecasts far faster than traditional methods.

Why it matters

This innovation teaches the value of integrating AI with domain-specific physics to drastically speed up complex simulations without sacrificing fidelity. It pushes scientists and practitioners to explore hybrid modeling approaches for efficient problem-solving.

Who's doing it

The collaborative team at UC San Diego and the Allen Institute for AI applied this model to produce actionable climate insights with unprecedented speed, influencing policy and research timelines.

Try it

  1. Visit UC San Diego’s project page for Spherical DYffusion (https://today.ucsd.edu/story/nine-breakthroughs-made-possible-by-ai).
  2. Download the model code and datasets provided.
  3. Run the model on your climate data using the recommended computational setup to generate accelerated long-term climate projections within a day.
