Earlier and faster heatwave onset on land under a warming climate
Heatwaves threaten ecosystems and societies. Previous studies have examined their frequency, intensity and duration, whereas long-term changes in heatwave timing—including onset, ending and season length—remain poorly understood, limiting our ability to anticipate heat-related risks. Here we analyse global changes in these metrics and onset-speed type from 1979 to 2023. Globally, heatwave onset advanced by 3.29 ± 0.12 days per decade, ending was…
Heat waves on land start earlier and develop faster, global analysis reveals
Heat waves over land worldwide are beginning earlier, ending later and occurring over longer seasons, while the first heat wave of the season has recently shifted toward faster onset, according to a new study published in Nature Climate Change.
Heatwaves Are Arriving Earlier and Striking Faster Across the World's
A 45-year global analysis shows heatwave seasons now begin more than three days earlier and end more than five days later each decade, with a recent shift towards faster, more abrupt heatwave onset concentrated in the world's drylands.
New measure of heat: Between 1979 and 2023, the first heat wave of the year shifted globally by an average of about two weeks forward, while the last one occurred about 24 days later. At the same time, first heat waves reached their temperature peak more frequently since the turn of the millennium, as a global analysis shows. Guangzhou (China). Heat waves become [...] The article Heat waves on land start earlier and develop faster appeared first…
