Scientists find evidence of long-term warming inside Greenland's ice sheet

Alaska Dispatch: In the mid-20th century, when Carl Benson was traveling Greenland gathering data he would use to write his Ph.D. thesis on the temperature, structure and composition of the hard-packed snow that covers that island, conditions deep beneath the surface were fairly consistent: white, firm, cold and dry. If you could imagine cutting a wall of Styrofoam, thats what it was like, said Benson, now a professor emeritus with the University of Alaska Fairbanks Geophysical Institute. Related: How dust...

Previous Greenland Ice Sheet Collapse Rose Sea Level up to 6 Meter
2014-06-26 22:32:00| Climate Ark Climate Change & Global Warming Newsfeed
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...

Skyscraper-Size Ice Structures Discovered Beneath Greenland Ice Sheet
2014-06-16 19:43:00| Climate Ark Climate Change & Global Warming Newsfeed
EcoWatch: Beneath the barren whiteness of Greenland, a mysterious world has popped into view. Using ice-penetrating radar, researchers have discovered ragged blocks of ice as tall as city skyscrapers and as wide as the island of Manhattan at the very bottom of the ice sheet, apparently formed as water beneath the ice refreezes and warps the surrounding ice upwards. The newly revealed forms may help scientists understand more about how ice sheets behave and how they will respond to a warming climate. The...
