With 2024 on track to become the hottetst year on record—surpassing even the unsettling heat of 2023—some regions are having to contend with a new phenomenon that neither climate models nor climate scientists can explain.
Researchers in the U.S. and Austria have created the first world map highlighting regions repeatedly experiencing intense heat waves that greatly exceed global warming models. The map, detailed in a November 26 study published in PNAS, shows these unexplainable hotspots residing on every continent, save for Antarctica. Alarmingly, the associated heat waves have killed tens of thousands of people and destroyed environments by causing droughts and wildfires, according to a Columbia Climate School statement.
“This is about extreme trends that are the outcome of physical interactions we might not completely understand,” Kai Kornhuber of the International Institute for Applied Systems Analysis in Austria and lead writer on the study said in the statement. “These regions become temporary hothouses.”
