West Antarctic Glacier Collapse Unstoppable
2014-05-13 16:04:00| Climate Ark Climate Change & Global Warming Newsfeed
Environment News Service: A rapidly melting section of the West Antarctic Ice Sheet appears to be in irreversible decline, with nothing to stop the entire glacial basin from disappearing into the sea, according to researchers at NASA and the University of California, Irvine. The study presents multiple lines of evidence, incorporating 40 years of observations that indicate the glaciers in the Amundsen Sea sector of West Antarctica "have passed the point of no return," warns glaciologist and lead author glaciologist Eric...

Antarctica Glacier Collapsing, Adding to Sea Level Rise
2014-05-12 20:31:00| Climate Ark Climate Change & Global Warming Newsfeed
National Geographic: A massive glacier system in West Antarctica has started collapsing because of global warming and will contribute to significant worldwide sea-level rise, two teams of scientists warn in a pair of major studies released Monday. Scientists had previously thought the two-mile-thick (3.2 kilometers) glacier system would remain stable for thousands of years, but new research suggests a faster time frame for melting. A rapidly melting section of the West Antarctic Ice Sheet appears to be in irreversible...
CU-Boulder prof helps lead effort map virtually every glacier on Earth
2014-05-08 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Daily Camera: A newly published study led by a glaciologist at the University of Colorado and a Canadian colleague has finished mapping virtually every glacier on Earth, part of an effort to learn more about rising seas as man-made gases warm the planet. The study, billed as the Randolph Glacier Inventory after the town in New Hampshire which served as one of the meeting places for the researchers mapped and catalogued roughly 198,000 glaciers. The work included contributions from 74 scientists representing...
Glacier Fluctuations Influenced by Temperature Rather than Weather, Study Finds
2014-04-16 22:32:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World: At the height of the last Ice Age, the expansion and contraction of glaciers in Africa's Rwenzori Mountains were driven by air temperature, rather than precipitation, according to new research that carries with it a host of implications affecting glaciers today. The study, led by Dartmouth College researchers and financed by National Geographic Society and the National Science Foundation, supports the idea that many of today's tropical glaciers are shrinking largely because of a warming climate,...

Wrinkly radar rainbows reveal a galloping glacier
2014-03-20 20:17:00| Climate Ark Climate Change & Global Warming Newsfeed
New Scientist: The diaphanous sheen of a butterfly wing? Or the exquisite iridescence of a soap bubble? Surprisingly, it's neither. This is a radar image snapped from low Earth orbit, showing the biggest glacier in the Arctic as its ice field inexorably grinds its way towards the open ocean. Radar images of the Petermann Glacier in Greenland, taken 24 days apart, were combined to create this colourful interferogram that highlights movement as small as a few centimetres. The rainbow interference fringes are widely...
