Glaciers’ Faster Pace May Be Due to Warming
Climate warming is the likely culprit behind the fast retreat of two of Greenland’s largest glaciers, scientists told a meeting of the American Geophysical Union on Thursday.
One of the glaciers, Kangerdlugssuaq, is moving at about nine miles a year compared with three miles a year in 2001.
The other glacier, Helheim, is speeding at about seven miles a year -- up from four miles a year during the same period.
Sea levels have risen globally 4 to 8 inches over the last century because of melting glaciers and polar ice.
Melting of Greenland ice is estimated to be responsible for about 7% of the increase.
