The polar ice sheets are changing. If the land-based ice sheets of Greenland or Antarctica melt or fall into the sea, global sea levels will rise calamitously. Liquid water forms at the base of the ice sheets, where it “greases” their slide toward the sea. Robin Bell will talk about newly discovered lakes and rivers beneath the thick Antarctic ice sheet. As part of the International Polar Year, a team of Lamont scientists including Dr. Bell, will travel to the middle of Antarctica to unlock these mysteries.
