California says it is preparing for its worst drought season ever after the wildfires that engulfed 20,000 acres around San Diego. Thousands of evacuees returned home over the weekend after firefighters contained the blaze. Speaking to ABC News, California Gov. Jerry Brown said thousands of additional firefighters will be needed in a state on the “front lines” of climate change.

Gov. Jerry Brown: “We’re getting ready for the worst. Now, we don’t want to anticipate before we know, but we need a full complement of firefighting capacity. The state’s climate appears to be changing. The scientists tell us that definitely. So, we’ve got to gear up here. … We here in California are on the front lines. We’ve got to deal with it. We’ve already appropriated $600 million. We have 5,000 firefighters. We’re going to need thousands more. And in the years to come, we’re going to have to make very expensive investments and adjust. And the people are going to have to be careful of how they live, how they build their homes and what kind of vegetation is allowed to grow around them.”
