http://www.wral.com/nasa-spots-worrisom ... /13637804/ 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 of West Antarctica" shows the melt is happening faster than scientists had predicted, crossing a critical threshold that has begun a domino-like process. |

"Ice is melting in the western Antarctic at an unstoppable pace, scientists said Monday, warning that the discovery holds major consequences for global sea level rise in the coming decades. The speedy melting means that prior calculations of sea level rise worldwide made by the Intergovernmental Panel on Climate Change will have to be adjusted upwards, scientists told reporters. "A large sector of the West Antarctic ice sheet has gone into a state of irreversible retreat. It has passed the point of no return," said Eric Rignot, professor of Earth system science at the University of California Irvine. "The retreat of ice is unstoppable," he said, noting that surveys have shown there is no large hill at the back of these glaciers that could hold back the melting ice. "This retreat will have major consequences for sea level rise worldwide," he added, anticipating the melting will take place largely in the next two centuries. "It will raise sea level by 1.2 meters or four feet," said Rignot, whose paper appears in the peer-reviewed Geophysical Research Letters, a journal of the American Geophysical Union." http://news.msn.com/world/west-antarcti ... =ansnews11 The thing is, sea level rise is the least of the problems of CAGW. If this is unstoppable, I wonder about the open Arctic ocean warming and the tundra methane to ocean methane self release points. I hope we have 9 years left to stop it by a 90% emissions reduction, we may not. |

Couldn't help but be a jack ass, huh? Area and volume are not the same, idiot. |

Sea ice floats on the water and does not affect sea level. It expands and contracts the area covered with the seasons. The glacial ice, which was the subject of the article, rests on land and does affect sea level. Glacial ice and sea ice are very different things. The lack of understandingb of even basic science is telling in the replies by Milton. |
