North Atlantic Warming and the Retreat of Greenland’s Glaciers. Fiamma Straneo

Models do ‘okay’ at predicting changes in surface mass balance of Greenland’™s ice sheets, says Fiamma Straneo. They don’t do so well, and therefore are not very useful, when it comes to predicting the accelerated melting that is now occurring and which, she says, now accounts for about one-fourth of global sea level rise. In this presentation she reviews her studies of what is happening in that dynamic space at the edge of the ice sheets where atmosphere, ocean and glacier all come together, and the various mechanisms proposed as contributing to ice sheet loss.
Straneo has led over 15 field expeditions in the polar regions using a wide range of platforms that include research vessels, fishing boats, inflatables, helicopters and snowmobiles. She serves on many national and international scientific panels including the US CLIVAR (Climate Variability and Predictability) Working Group on Ice Sheet-Ocean Interactions in Greenland, the steering committee of the International Arctic-Subarctic Ocean Fluxes Group, the Atlantic Meridional Overturning Circulation Science Team and the Arctic Observing Change Panel of SEARCH.
