Greenland's glaciers could lose more ice than predicted, study says
Greenland is known as the largest contributor to rising sea levels but a new study explores how the island's glaciers could lose more ice than previously predicted.
The three largest glaciers, Jakobshavn Isbræ, Kangerlussuaq and Helheim, are responsible for about 12% of the entire ice sheet and hold enough ice to raise sea levels by around 1.3 meters, or about 4.3 feet, according to the study published Tuesday in Nature.
Together, the three glaciers have already contributed about 8.1 millimeters or .32 inches to global sea levels between 1880 and 2012, the authors of the study said. They used historical photographs to calculate the amount of ice lost during that time frame.
If drastic efforts are not made to cut global greenhouse gas emissions, climate change models predict that Earth's temperature will rise 3.7 degrees Celsius above pre-industrial revolution temperatures by the end of the century.
