Statements

A heatwave is an extended period of unusually high temperatures over a large area, lasting from a few days to several weeks. It involves significant warming or an influx of very warm air, exceeding local climatological thresholds. Human-induced greenhouse gas forcing is the main driver of observed increases in both hot and cold extremes globally, including heatwaves.
