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. In a first application, the technique revealed sharper-than-ever details about Greenland's massive ice sheet, including that the rate at which it is melting might be accelerating more slowly than predicted. Princeton University researchers developed a...

Anthropogenic Climate Change Leads To Melting Glaciers And Rising Sea Level
2012-11-14 15:22:41

University of Innsbruck Between 1902 and 2009, melting glaciers contributed 11 cm to sea level rise. They were therefore the most important cause of sea level rise. This is the result of a new assessment by scientists of the University of Innsbruck. They numerically modeled the changes of each of the world´s 300 000 glaciers. Until 2100, glaciers could lead to an additional 22 cm of sea level rise. Since 1900 the global sea level has risen by approximately 20 cm. Melting glaciers...

Antarctic Ice Facing Changes By Fast-Flowing Glaciers
2012-09-19 14:14:23

Lee Rannals for redOrbit.com — Your Universe Online 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 team tested high-resolution model simulations against reconstructions of the Antarctic ice sheet from 20,000 years ago. Writing in the journal Proceedings of the National Academy of Sciences (PNAS), they said they used a new model during their study, capable...

Greenland Summer Ice Melt Breaks Record Month Before Season Ends
2012-08-16 11:14:51

April Flowers for redOrbit.com - Your Universe Online 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. Melting over the Greenland ice sheet shattered the seasonal record on August 8 this year — a full four weeks before the close of the melting season, reports Marco Tedesco, assistant professor of Earth and atmospheric sciences at The City College of New York. This year,...

Greenland's Rapid Ice Sheet Recession Hard To Predict
2012-08-03 13:01:47

Brett Smith for redOrbit.com - Your Universe Online Despite the rapid thaw of the Greenland Ice Sheet, scientists are still far from even being able to predict its disappearance. Recent research conducted by an international team of scientists provided evidence that this is not the first time in modern history that the ice sheet has receded and then stabilized again. Research and news reports surrounding the melting of polar and sub-polar ice often has a doom and gloom tone, but the...

Greenland Ice Melt Is "Unprecedented"
2012-07-25 06:04:10

Lee Rannals for redOrbit.com - Your Universe Online Satellites have revealed that Greenland's surface ice cover has melted this month more than any time in over 30 years of satellite observations. NASA said that nearly the entire ice cover of Greenland experienced some degree of melting at its surface this past month. Measurements from three independent satellites were analyzed by NASA and university scientists, who found that 97 percent of the ice sheet surface in Greenland thawed...

Greenland Glacier Loses An Ice Island Twice The Size Of Manhattan
2012-07-18 07:11:16

redOrbit Staff & Wire Reports - Your Universe Online 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. Muenchow credits Trudy Wohleben of the Canadian Ice Service for first noticing the fracture. MODIS, the Moderate Resolution Imaging Spectroradiometer aboard...

Antarctica Ice Sheet May Begin Melting Rapidly By Century's End
2012-05-09 13:58:16

Scientists report in the journal Nature that an Antarctic ice sheet may start to melt rapidly in this century. The finding, made by climate researchers of the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association, refute a widely believed theory that ice shelves in the Weddell Sea would not be affected by global warming due to the peripheral location of the sea. "The Weddell Sea was not really on the screen because we all thought that unlike the Amundsen...
