NASA: 10,000-Year-Old Ice Shelf in Antarctica Soon Be Completely Gone
2015-05-16 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Slate: Earth's polar regions are in the midst of a stunning transformation. As global warming accelerates, evidence of change is perhaps most obvious in our planet's ice. More than a decade ago, scientists watched in awe as Antarctica's Larsen B Ice Shelf shattered almost completely in just six weeks. No one had ever seen such a large mass of ice vanish so quickly. Now, a new study from NASA, released this week, predicts that what remains of Larsen B will be totally gone in less than five years. Since...

NASA finds Antarctic ice shelf a few years from disintegration
2015-05-15 04:19:00| Climate Ark Climate Change & Global Warming Newsfeed
Reuters: The last intact section of one of Antarctica's mammoth ice shelves is weakening fast and will likely disintegrate completely in the next few years, contributing further to rising sea levels, according to a NASA study released on Thursday. The research focused on a remnant of the so-called Larsen B Ice Shelf, which has existed for at least 10,000 years but partially collapsed in 2002. What is left covers about 625 square miles (1,600 square km), about half the size of Rhode Island. Antarctica has...
The ABCs of Antarctic Ice Shelf Melting
2015-05-13 23:02:00| Climate Ark Climate Change & Global Warming Newsfeed
Climate Central: January 1995 marked a seminal moment in modern Antarctic history, with the crumbling of the Larsen A ice shelf, a floating plain of ice fed by glaciers on the Antarctic Peninsula. Less than a decade later, its southern neighbor, the Larsen B ice shelf, disintegrated, stunning polar scientists. After the spectacular collapses of Larsen A and B, scientists began keeping a close watch on the next ice shelf to the south, the Larsen C, which has shown some worrying signs of thinning. At about the area...

Antarctic Ice Shelf Thinning from Above... and Below
2015-05-13 19:06:00| Climate Ark Climate Change & Global Warming Newsfeed
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...

Antarctic ice shelf is thinning from above and below

ScienceDaily: A decade-long scientific debate about what's causing the thinning of one of Antarctica's 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...
