Previous Greenland Ice Sheet Collapse Rose Sea Level up to 6 Meter

Nature World: More than 400,000 years ago, a warming period pushed Greenland's ice sheet past its limit and raised global sea levels up to 6 meters, according to new research. The results may give us a glimpse as to what may happen as a result of Greenland's current climate-induced melting dilemma. Known as the Marine Isotope Stage 11, this exceptionally long warming period between ice ages resulted in a global sea level rise of about 6-13 meters above present, caused by changes in the Earth's orbit around...

Greenland Ice Sheet Collapse Linked To Sea Level Rise 400,000 Years Ago: Study

2014-06-26 22:18:00| Climate Ark Climate Change & Global Warming Newsfeed

RedOrbit: A new study suggests that a warming period more than 400,000 years ago pushed the Greenland ice sheet past its stability threshold, resulting in a nearly complete deglaciation of southern Greenland and raising global sea levels some 4-6 meters. The study is one of the first to zero in on how the vast Greenland ice sheet responded to warmer temperatures during that period, which were caused by changes in the Earth`s orbit around the sun. Results of the study, which was funded by the National...
