James Balog, one of the world's premier cinema photographers, has been documenting the erosion of glaciers in Switzerland, Greenland, Iceland, and Alaska. He joins Bill to share his photos and discoveries, describing his process and transformation from climate change skeptic to true believer. Afterward, Bill explores a judicial system under partisan attack. Thirty-eight states now elect their high court judges. Over the last decade, $200 million -- much of it secret and tied to partisan agendas -- has been pouring into these judicial campaigns. A bipartisan coalition called Justice Not Politics is fighting back. Its co-founders Democrat Sally Pederson and Republican Joy Corning, each of whom served Iowa for eight years as lieutenant governor explain what's at stake when justices are at the mercy of partisan passions and money in politics.
