Latest Ice sheets Stories
In a new study that ends 20 years of uncertainty, an international team of satellite experts have produced the most accurate assessment of ice losses from Antarctica and Greenland to date.
An enhanced approach to capturing changes on the Earth's surface via satellite could provide a more accurate account of how ice sheets, river basins and other geographic areas are changing as a result of natural and human factors.
Since 1900 the global sea level has risen by approximately 20 cm. Melting glaciers are one of the causes – along with warming and thereby expanding sea water, melting Greenland and Antarctic ice sheets, and changing terrestrial water storage in dammed lakes and groundwater reservoirs.
A new study found that fast-flowing and narrow glaciers could trigger massive changes in the Antarctic ice sheet, inevitably adding sea-level rise and ice-sheet decay.
The summer melting season in Greenland usually lasts from June when the first puddles of meltwater appear, to September when temperatures begin to cool again.
Despite the rapid thaw of the Greenland Ice Sheet, scientists are still far from even being able to predict its disappearance.
Satellites have revealed that Greenland's surface ice cover has melted this month more than any time in over 30 years of satellite observations.
Andreas Muenchow, associate professor of physical ocean science and engineering in University of Delaware’s College of Earth, Ocean, and Environment, reports the calving of an island two times the size of Manhattan on July 16, 2012, in his “Icy Seas” blog.
