Warmer Ocean Water Is Key Factor in Melting Ice Shelves, Study Says
2013-09-13 19:01:00| Climate Ark Climate Change & Global Warming Newsfeed
Yale Environment 360: Recent research into one of West Antarctica's most rapidly melting glaciers and ice shelves has shown that rising ocean temperatures and a series of channels lacing the underside of the shelf are the key factors in the rapid thinning of the shelf and the swift advance of the glacier behind it. Reporting in NASA Edge of Pine Island ice sheet Science, U.S. scientists said that instruments deployed on and under the Pine Island Glacier and ice shelf over the past two years have shown that warmer ocean...
Warm Water Under Antarctic Glacier Spurs Speedy Melting Rate
2013-09-13 06:00:00| Climate Ark Climate Change & Global Warming Newsfeed
LiveScience: A two-month-long expedition to one of the most remote sites on the planet the sprawling Pine Island Glacier in Antarctica has revealed that currents of warm water beneath the glacier are melting the ice at a staggering rate of about 2.4 inches (6 centimeters) per day. An international team of researchers journeyed to the southernmost continent to study the Pine Island Glacier, which is the longest and fastest-changing glacier on the West Antarctic Ice Sheet. This region, in the far reaches of...
Sorry, skeptics: Arctic ice is still melting quickly this summer
2013-09-11 20:26:00| Climate Ark Climate Change & Global Warming Newsfeed
Grist: First the good news: Arctic ice melt has not been as extreme this summer as during last year`s historic collapse. The bad news is that the melt has been more extreme this summer than the 20-year average - no surprises there, given the icy clime`s rapid decline. The Arctic`s August 2013 ice coverage is shown in the image on the right. The black cross shows the North Pole and the magenta outline shows the average ice cover at the same time of year from 1981 to 2010. "Sea ice continued its...
Newfangled Icepod Tracks Greenlands Melting Ice Sheets

Guardian: The LC-130 Hercules flew low over the ice sheet in a tight grid pattern, Teflon-coated landing skis barely 300 meters above the soft upper layer of snow. At the rear of the plane, scientists clustered round a monitor displaying a regular pattern of dark red waves generated by a radar signal. Somewhere in the vast, white emptiness below were two tiny cracks -- barely 4 inches across -- imperceptible to the naked eye from this altitude, especially beneath fresh snow. But the cracks ran across...

Soot from Europe's Industrial Age May Have Spurred Melting of Alps
2013-09-03 22:02:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World: Soot, also known as black carbon, could have been the reason behind the abrupt retreat of the mountain glaciers in the Alps starting in the 1860s, according to a new study published in the journal Proceedings of the National Academy of Sciences. If correct, the theory could solve a longstanding scientific debate as to why the glaciers began melting even decades before global temperatures started rising. Records dating back to the 1500s show that large valley glaciers in the Alps suddenly melted...
