Scientists use Earth’s ‘digital twin’ to sharpen climate forecasts

EU-funded project to create a computer simulation of the world could also model biodiversity or pandemics

Scientists in Europe are creating an unprecedented computer simulation of the planet’s atmosphere, oceans and land to improve weather forecasting and potentially model biodiversity or pandemics.

The EU-funded project to create Earth’s “digital twin” has developed digital models of climate change and extreme weather at a higher resolution than current forecasting systems, using AI and supercomputers.

The programme, called Destination Earth or DestinE, is moving into its next phase this week, widening its user base for practical applications. It has already been used in pilot projects including high-resolution urban heat maps for European cities, air pollution monitoring, and wildfire, flood and drought warnings.
