Sea level rise and eclipse phenomena highlight this episode. First Dave talks to NASA Oceanographer Josh Willis about two new studies. The first reports that sea level rise isn't increasing at a linear rate -- it is accelerating. The second study demonstrates how much our understanding of ice melt from Antarctica's glaciers has advanced in just the past few years. Then we revisit The Great American Eclipse of 2017 with Dr. Gordon Telepun. A plastic surgeon from Alabama, Telepun created the smart phone app Solar Eclipse Timer. His YouTube channel by the same name (as the app) features detailed explanations of the varied and amazing phenomena associated with total solar eclipses.
