Hey Smarties! We’re on the road to Boston for a live taping of “Make Me Smart” with special guest, historian Heather Cox Richardson. So today we’re bringing you an episode from the latest season of “How We Survive,” Marketplace’s climate solutions podcast. In this episode, Kai Ryssdal and the “How We Survive” team head to the very, very top of Alaska to understand how climate change and national security are converging in the Arctic.
