Scientists warn heatwaves will intensify for 1,000 years even after net zero

New climate modeling shows that heatwaves will keep getting hotter, longer, and more frequent for centuries-even after the world hits net-zero emissions. Delays of just a few years dramatically increase the likelihood of extreme, once-rare heat disasters, especially for countries near the equator. The research reveals that even reaching net zero by mid-century won't reverse the trend, and some regions will continue to see worsening heatwaves for a thousand years.
