Europe builds 'digital twin' of Earth to hone climate forecasts
L'Europe construit un "jumeau numérique" de la Terre pour affiner les prévisions climatiques
Voosen, Paul
<br>The European Union is finalizing plans for an ambitious "digital twin" of planet Earth that would simulate the atmosphere, ocean, ice, and land with unrivaled precision, providing forecasts of floods, droughts, and fires from days to years in advance. Destination Earth, as the effort is called, will also attempt to capture human behavior, enabling leaders to see the impacts of weather events and climate change on society and gauge the effects of different climate policies. By rendering the planet's atmosphere in boxes only 1 kilometer across, a scale many times finer than existing climate models, Destination Earth can base its forecasts on far more detailed real-time data than ever before. It will be a focal point of the Europe's plans for "exascale" supercomputing this decade.<br></p>
