Ai2 Partners with Google on NeuralGCM+ for Faster Climate Prediction

The Allen Institute (Ai2) announced a partnership with Google to develop NeuralGCM+, backed by a multi-million-dollar, three-year grant from Google.org and technical support from Google Research, with the team set to expand. The project builds on NeuralGCM, released in 2024, which simulates large-scale atmospheric dynamics with physics while handling processes like clouds with AI; Google Research previously used it for week-to-month-scale forecasting, whereas NeuralGCM+ targets climate prediction on yearly-to-decadal scales.

Confirmed

NeuralGCM+ will couple the atmospheric model with an ocean model (plus sea ice) to capture ocean heat uptake, add physical processes, and test warmer climate scenarios
Ai2's existing climate simulation accelerator, ACE (Ai2 Climate Emulator), is said to dramatically speed up climate simulation
The project plans to release models, frameworks, and documented workflows while improving related components, going fully open source
Official use-case example: forecasting changes in rainfall and water availability in regions like the US Southwest through mid-century

Why it matters

Ocean-atmosphere-sea ice coupling is a key challenge in climate prediction; extending NeuralGCM from weather-forecast scales to decadal climate scales marks a significant AI-for-Science advance in the climate domain
The open-source workflows mean academia and the public can reuse this climate modeling tool, supporting long-term planning research such as water resource management
