ProPublica reporter Abrahm Lustgarten says in the coming decades it's likely tens of millions of us will relocate to escape rising seas, punishing heat, floods and wildfires due to global warming. He says nine of the ten fastest growing regions of the country are on the front lines of the most severe and fast-changing climate conditions. His book is On the Move: The Overheating Earth and the Uprooting of America. Ken Tucker has high praise for Tierra Whack's new album, World Wide Whack.
