In this edition of In Depth we take on two water topics. First, there’s growing concern that a lot of the rainwater we’ve been getting is just going down the drain and out to sea. We plumb the depths of California’s water system to find out where it’s coming up short and what can be done to fix it. Then, new research suggests that the historical link between wet winters and less severe fire seasons has broken down. We discuss why even in the rainiest of years, we still can’t count out damaging wildfires.
