When we try to visualize the Arctic, we usually think of ice as far as the eye can see. But, unfortunately, that's changing. This week's guest, author Roy Scranton, gives us a first-hand glimpse into the rapidly melting polar cap up North. Scranton, who recently took a cruise through Greenland and Northern Canada for a piece published in The Nation magazine, presents us with the many challenges we face as this vast region undergoes vast transformation. Then, host Alex Wise and Scranton discuss Scranton's book, Learning How To Die In The Anthropocene, and how his time as a U.S. soldier in the Iraq War gave him a unique perspective on climate change and environmentalism.
