Dave talks to longtime friend of the program, Josh Willis, the Principal Investigator for NASA's OMG (Oceans Melting Greenland) program.
Josh was flying missions over the places where the glacial ice sheets meet the sea all summer and was joined by several major media outlets (like NBC with Al Roker pictured above) that highlighted the pace at which Greenlands glaciers are melting.
Josh tells about his research on how warming oceans are contributing to the rate of melting on the glaciers as they extend into the Atlantic Ocean.
While climate change is a very serious and somber matter, communicating the science of it can be a challenge that is sometimes best met with humor and Willis goes to comedy classes at Second City's Improv in Hollywood to work on his communication skills.
One of the ways he reaches out is with his alter ego, Climate Elvis, featured as one of last year's Flame Challenge entries for the Alan Alda Center for Communicating Science.
