NASA Scientist John Willis (fb: @climateelvis, tw, insta: @omgnasa) tells us about his research for Ocean's Melting Greenland (OMG), and his comedy work as Climate Elvis (https://youtu.be/WGfKRfyhvd0). We talk about the health, economic, migratory and other impacts of Global Climate Change. Plus, how to talk to uniformed skeptics. And some optimistic news about making a change!
