Beyond a wild ride of an interview, Eric Small gifted us a new favorite word that describes his hydrological research on water, energy and carbon budgets of the Earth's surface—ground-truthing. On today's episode, Eric explosively (i.e., like a Muppet) walks us through the practice of matching on-the-ground maps with satellite data. Beyond the sheer hilarity of his and Erika's conversation, what makes this such a fun interview is his unwavering belief that easy answers are hard to come by and they only get more complex the closer you choose to look.
