This week we are talking about the California drought. First we talk to Anthony Artusa, a meteorologist from the National Weather Service's Climate Prediction Center. He gives us a sense of what to expect from the current El Niño year and what it may or may not mean to California long-term. Then we talk to Peter Brewitt, who recently wrote about the millions of plastic shade-balls being used in LA’s main reservoir to try to slow evaporation. Might this potentially controversial innovation provide a lasting solution? Produced by Alex Wise.
