Every year, people in the American West die from scorching temperatures. Experts fear that the number of deaths is undercounted — and that as the climate continues to heat up, the death rate will rise.

Officially, California says 599 people died due to heat exposure from 2010 to 2019. But a Los Angeles Times investigation estimates the number is much higher: about 3,900 deaths.

Today we talk to Tony Barboza and Anna M. Phillips, who along with Sean Greene and Ruben Vives, spearheaded the L.A. Times investigation. We discuss why their count is so different from the state’s, who’s most vulnerable to the heat and how to protect yourself.
