On today’s show we talk to Cynthia Barnett, author of Rain: A Natural and Cultural History (Crown, April 2015). Barnett, an environmental journalist, takes us to Texas, India, and everywhere in between to explore how we make sense of the water that falls from the sky. Josh Hrala tells us how filmmakers might be the key to proving we did, in fact, land on the moon in 1969, and Mark Hay dissects the gruesome science of self-immolation.
