Today we're talking to Environmental Journalist and Pulitzer Prize Finalist Abrahm Lustgarten about his new book, On the Move: The Overheating Earth and the Uprooting of America. Lustgarten argues that the coming decades will redefine where human beings can live on the Earth, and that this change will fundamentally reshape both population centers around the globe and the US. We'll dig into what this means for areas at risk, like Houston, but also how we might prepare for new waves of international and intra-national migration.
