Paul Bierman is professor of environmental science at the University of Vermont, where he develops methods to understand ice and date rocks. His findings have been published in Science and Nature and in his recent book When The Ice Is Gone. On this episode of Nature Revisited, Bierman reveals a startling discovery about Greenland's rapidly melting ice sheet - it has melted naturally before, hundreds of thousands of years ago... Changes in Greenland due to a warming earth are already reverberating around the world, and Bierman explains how losing Greenland's ice will catalyze devastating events if we don't change course and address climate change now.
