Rapid studies are a big leap forward in understanding climate impact

Linking last month’s intense heatwave across South Asia to human-induced climate change shows the promise of rapid attribution studies.

As large swathes of India reeled under a brutal heatwave in late April, a group of scientists from across the world worked together to rapidly assess how climate change altered the likelihood and intensity of extreme temperatures.

Last week, the World Weather Attribution initiative—a collaboration of climate scientists—released its findings on the role human-induced global warming played in the heatwaves. It found that climate change made heatwaves across South Asia 30x more likely. A heatwave of this magnitude would be “virtually impossible” to have occurred without that, the scientists concluded. 

Worse, the heat index—which combines temperature and humidity to more …
