Climate change: Greenland melting tied to shrinking Arctic sea ice
2016-03-28 12:00:00| LifeSciencesWorld
[NEWS] Vanishing Arctic sea ice. Dogged weather systems over Greenland. Far-flung surface ice melting on the massive island. These dramatic trends and global sea-level rise are linked, according to a study coauthored by Jennifer Francis, a research professor in Rutgers University's Department of Marine and Coastal Sciences. During Greenland summers, melting Arctic sea ice favors stronger and more frequent “blocking-high” pressure systems, which spin clo…

Science Codex: Vanishing Arctic sea ice. Dogged weather systems over Greenland. Far-flung surface ice melting on the massive island. These dramatic trends and global sea-level rise are linked, according to a study coauthored by Jennifer Francis, a research professor in Rutgers University's Department of Marine and Coastal Sciences. During Greenland summers, melting Arctic sea ice favors stronger and more frequent "blocking-high" pressure systems, which spin clockwise, stay largely in place and can block cold,...
The Bizarre Reason Greenland Is Getting Darker Each Year
2016-03-03 14:47:00| Climate Ark Climate Change & Global Warming Newsfeed
Gizmodo: Greenland is one of the brightest spots on planet Earth, but ominously enough, its gleaming surface darkens with each passing year, thanks to a strange series of physical processes, one of which cannot be seen with the naked eye. According to a fascinating new study led by Columbia's Earth Institute and published today the journal The Cryosphere, which finds that Greenland's "albedo," or reflectivity, has been decreasing since the mid 90s. By the end of the 21st century, Greenland could be ten...

'Ice age blob' of warm ocean water discovered south of Greenland
2016-02-19 23:01:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: New research published in Scientific Reports in February indicates that a warm ocean surface water prevailed during the last ice age, sandwiched between two major ice sheets just south of Greenland. Extreme climate changes in the past Ice core records show that Greenland went through 25 extreme and abrupt climate changes during the last ice age some 20,000 to 70,000 years ago. In less than 50 years the air temperatures over Greenland could increase by 10 to 15 °C. However the warm periods were...
Ice sheet modeling of Greenland, Antarctica helps predict sea-level rise
2016-02-16 17:02:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: The Greenland and Antarctic ice sheets will make a dominant contribution to 21st century sea-level rise if current climate trends continue. However, predicting the expected loss of ice sheet mass is difficult due to the complexity of modeling ice sheet behavior. To better understand this loss, a team of Sandia National Laboratories researchers has been improving the reliability and efficiency of computational models that describe ice sheet behavior and dynamics. The team includes researchers Irina...
