Heat waves that lead to sudden and damaging drought are spreading across the globe at an accelerating rate, highlighting how climate change-fueled extremes can build dangerously off each other, a new study found.
Researchers from South Korea and Australia looked at compound extreme weather — a one-two punch of heat and drought — and found it increasing as the world warms. But what's rising especially fast is the more damaging type when the heat comes first and that triggers the drought. In the 1980s, that kind of extreme covered only about 2.5% of Earth's land each year. By 2023, the last year the researchers studied, it was up to 16.7%, with a 10-year average of 7.9%
