Get a reality check on the Antarctic meltdown and rising sea level
2014-05-14 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
NBC: Does the retreat of glaciers on the West Antarctic Ice Sheet mean we're in for an imminent climate catastrophe? The short answer is no. Is the ice sheet collapsing? That depends on your definition of "collapse." Are the two studies documenting Antarctica's meltdown worth all the buzz they've generated? Yes. Here's a reality check on some of the questions raised by this week's studies: What's happening to Antarctica's ice? The continent's glaciers are in a constant state of flux, Penn State...
5 myths about Antarctic melt
2014-05-14 15:40:00| Climate Ark Climate Change & Global Warming Newsfeed
LiveScience: News that the catastrophic collapse of the West Antarctic ice sheet is already underway, like other big reports about the southernmost continent, spur chatter and questions about what's really happening at the bottom of the world. We'll explain the reality behind some common misconceptions about big changes in Antarctica. 1. Antarctic ice is getting bigger, not shrinking! Yes, the Antarctic sea ice has been growing larger over the last few decades. But here's what people miss when they raise...
West Antarctic Ice Sheet unstoppable loss not unexpected by NASA Scientists
2014-05-14 03:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Clarksville: The new finding that the eventual loss of a major section of West Antarctica`s ice sheet "appears unstoppable" was not completely unexpected by scientists who study this area. The study, led by glaciologist Eric Rignot at NASA`s Jet Propulsion Laboratory, Pasadena, California, and the University of California, Irvine, follows decades of research and theory suggesting the West Antarctic Ice Sheet is inherently vulnerable to change. Although the Amundsen Sea region is only a fraction of the whole...
Shift in Antarctic Winds Drives "Collapse" of Glaciers
2014-05-14 00:31:00| Climate Ark Climate Change & Global Warming Newsfeed
National Geographic: The "unstoppable collapse" of glaciers in West Antarctica announced by scientists this week has one key cause: shifting winds. Stronger winds are pushing warm water under coastal glaciers and melting them. The process is expected to intensify in the coming decades. Two research papers published Monday found that six major glaciers along the Amundsen Sea in West Antarctica are thinning more rapidly than expected and contributing to sea-level rise. Warm water is coming into contact with the bottom...

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...
