Greenland's Rapid Ice Sheet Recession Hard To Predict
2012-08-03 13:01:47

Brett Smith for redOrbit.com - Your Universe Online Despite the rapid thaw of the Greenland Ice Sheet, scientists are still far from even being able to predict its disappearance. Recent research conducted by an international team of scientists provided evidence that this is not the first time in modern history that the ice sheet has receded and then stabilized again. Research and news reports surrounding the melting of polar and sub-polar ice often has a doom and gloom tone, but the...

Today the U.S. National Research Council released a synthesis of reports from thousands of scientists in 60 countries who took part in the International Polar Year (IPY) 2007-08, the first in over 50 years to offer a benchmark for environmental conditions and new discoveries in the polar regions. University of Massachusetts Amherst geosciences researcher and expert in the paleoclimate of the Arctic, Julie Brigham-Grette, co-chaired the NRC report, "Lessons and Legacies of the IPY 2007-08"...

GREENBELT, Md., March 15, 2012 /PRNewswire-USNewswire/ -- Researchers and flight crew with NASA's Operation IceBridge, an airborne mission to study changes in polar ice, began another season of science activity with the start of the 2012 Arctic campaign on March 13. From mid-March through mid-May, a modified P-3 from NASA's Wallops Flight Facility in Wallops Island, Va., will conduct daily missions out of Thule and Kangerlussuaq, Greenland --with one flight to Fairbanks, Alaska and...

Thickest Parts Of Arctic Ice Cap Are Melting Faster
2012-03-01 04:33:50

[ Watch the Video ] A new NASA study revealed that the oldest and thickest Arctic sea ice is disappearing at a faster rate than the younger and thinner ice at the edges of the Arctic Ocean´s floating ice cap. The thicker ice, known as multi-year ice, survives through the cyclical summer melt season, when young ice that has formed over winter just as quickly melts again. The rapid disappearance of older ice makes Arctic sea ice even more vulnerable to further decline in the summer,...

Arctic Sea Ice Continues Decline, Hits 2nd-Lowest Level
2011-10-05 10:11:51

[ Watch the Video ] Last month the extent of sea ice covering the Arctic Ocean declined to the second-lowest extent on record. Satellite data from NASA and the NASA-supported National Snow and Ice Data Center (NSIDC) at the University of Colorado in Boulder showed that the summertime sea ice cover narrowly avoided a new record low. The Arctic ice cap grows each winter as the sun sets for several months and shrinks each summer as the sun rises higher in the northern sky. Each year the...

Sea levels could be rising faster than scientists originally believed, thanks to the warming subsurface waters that could cause more rapid melting of ice sheets in Greenland and Antarctica, researchers from the University of Arizona are claiming. In a new study, University of Arizona Assistant Professor of Geosciences Jianjun Yin and colleagues analyzed 19 different climate models under which global warming would accelerate the melting of the world's largest ice sheets over the next two...

ESA's CryoSat team working on the Greenland ice sheet has been honored with a visit from a Dutch delegation including HRH Prince of Orange. The visit is part of a tour to learn more about climate change in polar regions and consequences for the environment. Prince Willem-Alexander's visit to Greenland was at the invitation of the World Wide Fund for Nature-Netherlands. The delegation included Johan van de Gronden, CEO of WWF-NL, Robbert Dijkgraaf, President of the Royal Dutch Academy of...

New research shows that hostile conditions on Mars were much worse 600,000 years ago than they are today, with evidence suggesting the red planet once had a much dustier, stormier atmosphere. NASA's Mars Reconnaissance Orbiter (MRO) discovered that the total amount of atmosphere on Mars changes significantly as the tilt of the planet's axis varies.  The process can affect the stability of liquid water -- if it exists on the surface "“ and can also increase the frequency and...
