Paonia author Craig Childs became a doomsday tourist to write his new new book. He traveled to the glaciers of Patagonia, the mountains of Tibet, and volcanoes of Hawai’i to learn how natural forces might wipe out civilization. Cheery, eh? But, Childs writes, “the interest is not merely prurient. This is what the earth is capable of. It’s something that should be known.” Childs speaks with host Ryan Warner about his book, "Apocalyptic Planet: A Field Guide to the Everending Earth.”
