Glaciers And Ice Caps To Dominate Sea Level Rise This Century, Says New Study

Ice loss from glaciers and ice caps is expected to cause more global sea rise during this century than the massive Greenland and Antarctic ice sheets, according to a new University of Colorado at Boulder study.

The researchers concluded that glaciers and ice caps are currently contributing about 60 percent of the world’s ice to the oceans and the rate has been markedly accelerating in the past decade, said Emeritus Professor Mark Meier of CU-Boulder’s Institute of Arctic and Alpine Research, lead study author. The contribution is presently about 100 cubic miles of ice annually — a volume nearly equal to the water in Lake Erie — and is rising by about three cubic miles per year.
