Antarctic ice melting so fast whole continent may be at risk by 2100
2015-10-12 17:32:00| Climate Ark Climate Change & Global Warming Newsfeed
Guardian: Antarctic ice is melting so fast that the stability of the whole continent could be at risk by 2100, scientists have warned. Widespread collapse of Antarctic ice shelves floating extensions of land ice projecting into the sea could pave the way for dramatic rises in sea level. The new research predicts a doubling of surface melting of the ice shelves by 2050. By the end of the century, the melting rate could surpass the point associated with ice shelf collapse, it is claimed. Related:...
Greenland's ice sheet 'plumbing' system revealed
2015-10-09 23:38:00| Climate Ark Climate Change & Global Warming Newsfeed
Asian News International: A team of researchers have shed light on the impact of climate change on plumbing system that governs the water flow in subglacial lake under the Greenland ice sheet. A team of experts, led by Dr Steven Palmer from the University of Exeter, has studied the water flow paths from one such subglacial lake, which drained beneath the ice sheet in 2011. The study shows, for the first time, how water drained from the lake - via a subglacial tunnel. Significantly, the authors present satellite observations...

Greenland Ice Sheet Has Unique 'Plumbing' System, New Study Shows

Nature World News: "Our research reveals details about the plumbing system beneath the Greenland ice sheet, which is important because the configuration of that system has an impact on the flow speed of the overlying ice," Dr. Steven Palmer, lead author of the study from the Geography Department at the University of Exeter, explained in a news release. For their study, researchers examined the flow paths of a subglacial lake that drained beneath the ice sheet in 2011. They discovered that the water drained from...

ScienceDaily: Pioneering new research sheds light on the impact of climate change on subglacial lakes found under the Greenland ice sheet. A team of experts, led by Dr Steven Palmer from the University of Exeter, has studied the water flow paths from one such subglacial lake, which drained beneath the ice sheet in 2011. The study shows, for the first time, how water drained from the lake -- via a subglacial tunnel. Significantly, the authors present satellite observations that show that a similar event happened...

Antarctic ice loss challenged by new NASA study
2015-10-07 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Sydney Morning News: The hostile home of the blizzard may have been more like a climate change friend. A new NASA study challenges an accepted belief that Antarctica has lost billions of tonnes more ice to melt, than it has gained through snowfall. Instead, according to the study findings, the vast East Antarctic ice sheet accumulated snow at a high enough rate in recent decades to outweigh losses elsewhere around the frozen continent, and to reduce sea level. The fate of Antarctica's land-bound ice is seen...
