Researchers are forecasting a higher-than-usual season for hurricanes this summer because of lingering El Nina conditions. Climatewire science reporter Chelsea Harvey goes over the forecasts for extreme weather. Adam Sobel, an atmospheric scientist at Columbia University, explains how difficult it is to attribute any storm or any active season to climate change. And Greenwire climate reporter Arianna Skibell describes a lab in South Carolina where scientists douse homes in fire, wind, rain and hail to figure out the most resilient building materials.
