Antarctic glaciers thinning so fast, it's like a switch was flipped

Christian Science Monitor: A new study has recorded a sudden and rapid thinning of once-stable glaciers along the southern Antarctic Peninsula, demonstrating that significant changes in glacier mass can occur surprisingly quickly as ocean and air temperatures rise. The findings support what researchers have been seeing in other parts of Antarctica, with scientists warning last year that four key glaciers on the West Antarctic Ice Sheet appear to be on the verge of wholesale retreat with nothing to stop them. The new...

Antarctic Ice Shelves found to be thinning from the top AND the bottom

Environmental News Network: A decade-long scientific debate about whats causing the thinning of one of Antarcticas largest ice shelves is settled this week (Wednesday 13 May) with the publication of an international study in the journal The Cryosphere. The Larsen C Ice Shelf whose neighbours Larsen A and B, collapsed in 1995 and 2002 is thinning from both its surface and beneath. For years scientists have been unable to determine whether it is warming air temperatures or warmer ocean currents that were causing the...
Antarctic Ice Shelf Thinning from Above... and Below

Nature World: One of Antarctica's largest ice shelves is thinning from above and below, helping scientists finally understand just what exactly is causing this rapid ice melt, according to new research. The Larsen C Ice Shelf - whose neighbors Larsen A and B, collapsed in 1995 and 2002 - has long puzzled scientists. They have debated for decades whether warming air temperatures or warmer ocean currents are behind the collapse of the Antarctic Peninsula's floating ice shelves. But new findings, published...

Antarctica's ice shelves are thinning fast

LiveScience: Antarctica's floating ice collar is quickly disappearing in the west, a new study reports. In the Bellingshausen and Amundsen seas two of West Antarctica's melting hotspots some ice shelves lost 18 percent of their thickness in the past decade, researchers said. The most dramatic shrinkage occurred in the Bellingshausen Sea's Venable Ice Shelf, which lost ice at an average rate of 118 feet (36 meters) per decade in the past 18 years. At that rate, the entire ice shelf could disappear within...
