Episode 3 (12), “The Uprooted” (November 9, 2016): In Africa, Thomas Friedman finds an increasing population of refugees fleeing wars, rising sea-levels, desertification and hurricanes, as up to 1 billion people are expected to become climate refugees over the next century. Young men left without the prospect of farming are more likely to join extremist groups. Don Cheadle explores how governor Jerry Brown is fighting both climate change and the historic California drought. A Central Valley scientist, James S.
