Short Wave: Scientists Are Racing To Save Sequoias

Based on early estimates, as many as 10,600 large sequoias were killed in last year's Castle Fire — up to 14% of the entire population. The world's largest trees are one of the most fire-adapted to wildfires on the planet. But climate change is making these fires more extreme than sequoias can handle. It's also worsening drought that is killing other conifer trees that then become a tinder box surrounding the sequoias, reports climate correspondent Lauren Sommer in this episode of NPR's daily science podcast, Short Wave.
