As the U.S. suffers through its worst drought since the 1950s, the author and environmental correspondent Mark Hertsgaard joins us to discuss his new initiative, "Climate Parents." In a new article, "Parents Need to Act Against Climate Change for Their Kids' Sake," Hertsgaard writes: "Beyond the distress and discomfort, the record-breaking heat raises a puzzling question for anyone who cares about the future of our young people. The laws of physics and chemistry — the fact that carbon dioxide remains in the atmosphere for decades after being emitted — mean that man-made global warming is just getting started on this planet. As a result, my [daughter] Chiara and millions of other youth around the world are now fated to spend the rest of their lives coping with the hottest, most volatile climate in our civilization's 10,000-year history." Hertsgaard is author of the book, "HOT: Living Through the Next Fifty Years on Earth," is an environment correspondent for The Nation, and is a fellow at the New America Foundation. "We actually subsidize Shell, and Exxon Mobile, and Peabody coal, and all of these big fossil fuel companies," Hertsgaard says. "We subsidize them to wreck the planet for our kids. That has to change."
