Google AI predicts long-term climate trends and weather — in minutes

Models that are more reliable and less energy-intensive could help us to better prepare for extreme weather.

A computer model that combines conventional weather-forecasting technology with machine learning has outperformed other artificial intelligence (AI)-based tools at predicting weather scenarios and long-term climate trends.

The tool, described in Nature on 22 July1, is the first machine-learning model to generate accurate ensemble weather forecasts — ones which present a range of scenarios. Its development opens the door for forecasting that is faster and less energy-intensive than existing tools, and more detailed than approaches based solely on AI.
