AI in Climate Research: Detecting Climate Extremes
Climate extremes such as heat waves, heavy rainfall or droughts have far-reaching impacts on ecosystems, agriculture, water resources and also on human health. In order to understand recent climate extremes and to be able to assess the resulting climate risks, they must be examined in a historical context. How do these recent extremes compare to past events throughout the 20th Century, and what are the regional variations of the long term trends? To answer this question, data analysts of DKRZ have developed a method that can effectively reconstruct incomplete observation data on climate extremes by using methods of artificial intelligence (AI). The results of the study were published in the internationally renowned journal “Nature Communications” at the end of October 2024.
