'Past The Point Of No Return:' An Antarctic Ice Sheet Slow Collapse
2014-05-12 22:03:00| Climate Ark Climate Change & Global Warming Newsfeed
National Public Radio: NASA held a press conference to discuss the stability of the West Antarctic Ice Sheet and its potential contribution to future sea level rise. The researchers announced that the ice sheet's collapse is both underway and unstoppable.
NASA spots worrisome Antarctic ice sheet melt
2014-05-12 21:44:00| Climate Ark Climate Change & Global Warming Newsfeed
Associated Press: The huge West Antarctic ice sheet is starting a glacially slow collapse in an unstoppable way, two new studies show. Alarmed scientists say that means even more sea level rise than they figured. The worrisome outcomes won't be seen soon. Scientists are talking hundreds of years, but over that time the melt that has started could eventually add 4 to 12 feet to current sea levels. A NASA study looking at 40 years of ground, airplane and satellite data of what researchers call "the weak underbelly...
NASA spots worrisome Antarctic ice sheet melt
2014-05-12 21:40:00| Climate Ark Climate Change & Global Warming Newsfeed
Associated Press: It's likely because of man-made global warming and the ozone hole which have changed the Antarctic winds and warmed the water that eats away at the feet of the ice, researchers said at a NASA news conference Monday. "The system is in sort of a chain reaction that is unstoppable," said NASA glaciologist Eric Rignot, chief author of the NASA study in the journal Geophysical Research Letters. "Every process in this reaction is feeding the next one." Curbing emissions from fossil fuels to slow climate...
Collapse of Antarctic glaciers seems to be unstoppable
2014-05-12 20:18:00| Climate Ark Climate Change & Global Warming Newsfeed
New Scientist: Parts of the West Antarctic Ice Sheet are already collapsing and probably can't be saved. Two independent studies suggest that several glaciers have gone past the point of no return, dooming them to fall into the sea and cause several metres of sea level rise. However the collapse will take centuries. "A large sector of the West Antarctic Ice Sheet has gone into irreversible retreat," says Eric Rignot of the University of California at Irvine, who led one of the studies. "We've gone beyond the...

Scientists Warn of Rising Oceans as Antarctic Ice Melts
2014-05-12 18:55:00| Climate Ark Climate Change & Global Warming Newsfeed
New York Times: The collapse of large parts of the ice sheet in West Antarctica appears to have begun and is almost certainly unstoppable, with global warming accelerating the pace of the disintegration, two groups of scientists reported Monday. The finding, which had been feared by some scientists for decades, means that a rise in global sea level of at least 10 feet may now be inevitable. The rise may continue to be relatively slow for at least the next century or so, the scientists said, but sometime after that...
