Significant Contribution of Greenland's Peripheral Glaciers to Sea-Level Rise
2013-03-18 20:30:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: Glaciers at the edge of Greenland which are not connected to its huge ice sheet, or can be clearly separated from it, are contributing to sea-level rise much more than previously thought. Scientists from the University of Zurich together with colleagues from Denmark have found that, though these peripheral glaciers make up just 5-7 % of total ice coverage on the land mass, they account for up to 20% of the rise in sea level created by the region's melting. The scientists looked at glaciers which...

Study finds Greenlands ice may not be as vulnerable to climate change as scientists feared

Houston Chronicle: New research suggests that Greenland`s vast ice sheet isn`t as fragile as some climate scientists feared. The work, published in Nature this week (see abstract), indicates the majority of ice on Greenland could remain intact for hundreds of years even if the planet warms considerably. The study used ice cores to study conditions during a period of natural global warming that occurred between 115,000 and 130,000 years ago, when temperatures were about 14.5 Fahrenheit degrees higher than they...
Greenlands Ice Sheet More Stable Than Once Believed

Climate Central: The enormous sheets of ice that lie atop Greenland may not be as prone to catastrophic melting as many scientists thought, even if the planet continues to warm and temperatures remain high for hundreds of years. But while that may sound like good news, new evidence also suggests that parts of the even vaster ice sheets that lie atop Antarctica could be more unstable than once believed. That's the conclusion of scientists who have been drilling deep into the Greenland ice sheet since 2007, in a...

Eyes Turn to Antarctica as Study Shows Greenland's Ice Has Endured Warmer Climates

New York Times: An important discussion is developing among climate and polar researchers around the central point of a landmark Nature paper on Greenland conditions during Earth`s last (very warm) interval between ice ages. The paper, in which a critically important Greenland ice core is analyzed by 133 authors from a host of research centers, concludes that the vast ice sheet largely endured over a period of 6,000 years that was warmer than what is forecast for coming decades. The graph above, with the Eemian...
Why Greenlands Melting Could Be the Biggest Climate Disaster of All

Climate Desk: As an expert on Greenland who has traveled 23 times to the massive, mile thick northern ice sheet, Box has shown an uncanny ability to predict major melts and breakoffs of Manhattan-sized ice chunks. A few years back, he foretold the release of a "4x Manhattans" piece of ice from Greenland`s Petermann Glacier, one so big that once afloat it was dubbed an "ice island." In a scientific paper published in February of 2012, Box further predicted "100 % melt area over the ice sheet" within another decade...
