Jensen Huang’s Nvidia is building a digital twin of Earth; AI could help cities simulate floods, storms and future climate risks

Nvidia, founded and led by Jensen Huang, is developing Earth-2, an AI-powered platform designed to simulate and visualise weather and climate conditions at increasingly high resolution. The project combines artificial intelligence, GPU computing, physical simulations and geospatial visualisation to create a digital twin of the planet. Its models can generate global forecasts, downscale atmospheric information to much finer scales and simulate the development of hazardous weather. The technology is moving beyond conventional forecasting into applications such as flood-risk assessment, storm modelling and climate resilience planning. Nvidia’s work with weather agencies, climate researchers and risk-modelling companies has already produced simulations covering hundreds of years of hypothetical atmospheric conditions, showing how AI-generated scenarios could help cities and infrastructure planners examine extreme events that are poorly represented in historical records.
