Heatwaves loom as a growing threat to humanity in a warming climate. This summer alone, in the northern hemisphere, thousands have died during extreme heat events. It's driving researchers to find out more about the point when heat turns deadly.
The take-away is that higher temperatures with low humidity are more deadly than previously thought, so that you can have deadly heat below the wet bulb threshold.
