A team of German scientists at the Max Planck Institute for Meteorology has developed a highly detailed digital twin of Earth, revolutionizing climate study. This simulation, with a resolution of 1.25 kilometers, comprises 672 million cells—half focused on land and ocean surfaces, and the other half on the atmosphere. It models both “fast” meteorological processes, like water and wind, and “slow” climatological systems, including the carbon cycle and ocean chemistry.
This new model is 40 times more precise than previous ones, allowing researchers to predict climate change impacts, such as rising sea levels and localized weather changes, with unprecedented accuracy. It also aims to solve mysteries like the behavior of the Atlantic Meridional Overturning Circulation (AMOC), crucial for Europe’s climate.
Though primarily intended for long-term climate predictions rather than daily weather forecasting, this advancement hints at a future where extended forecasts could rival short-term ones in reliability.
