Climate change crisis: Massive glacier melting at alarming rate
In an unprecedented study American and British scientists have discovered warm ocean water underneath a massive glacier in western Antarctica. That warm water could speed its melt in a region with the potential to eventually unleash more than 10 feet of sea level rise. The scientists also found that the glacier is melting at a rate of about 50 billion tons of ice per year. Brian and John speak with Eric Rignot, a co-investigator for the organization that conducted this study, the MELT project at the International Thwaites Glacier Collaboration, and the Chair and Professor of Earth System Science at the University of California Irvine.
