Last year was California’s most destructive fire season. That is, until this year. And while climate change cannot be blamed for individual fires like those currently burning at both ends of the state, scientist Daniel Swain says climate change is a “threat multiplier,” creating conditions that will lead to more large, fast-moving and dangerous wildfires. It’s a trend which Governor Jerry Brown has dubbed “the new abnormal.” Swain joins us to talk about what he calls “an astonishing multi-year fire siege” and what steps can be taken to address the risks.
