Scientist Daniel Swain on "Unprecedented Climate Conditions" Contributing to Deadly CA Wildfires

In California, at least 40 people have died, hundreds are missing, and thousands of homes have been destroyed by uncontrollable wildfires. More than 11,000 firefighters are battling the wildfires, with the support of hundreds of fire engines and dozens of helicopters and airplanes. Many of the firefighters are prisoners, who are working for as little as $1 a day. Among the victims of the wildfires were elderly residents of Sonoma County, where authorities say their bodies were so charred, the only way to identify some of them was by the serial numbers on artificial joints or other medical devices. We speak with Daniel Swain, a climate scientist at UCLA and author of Weather West, the California Weather Blog.
