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,...
Microbes Are Likely Speeding Up the Melting of the Glaciers

Yale Environment 360: As if soaring global temperatures werent bad enough, scientists reported this week that microbes are also speeding up the melting of Arctic ice. The problem lies in cryoconite, the soil-like composite of dust, industrial soot and photosynthetic bacteria that darkens the surface of ice and causes it to melt, scientists from Aberystwyth University in Wales said. As it melts, ice leaves behind small water-filled holes full of bacteria. The sun-loving microbes then shape the pockmarks depth and size...
Greenland's ice is getting darker, increasing risk of melting
2016-03-03 23:02:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: Greenland's snowy surface has been getting darker over the past two decades, absorbing more heat from the sun and increasing snow melt, a new study of satellite data shows. That trend is likely to continue, with the surface's reflectivity, or albedo, decreasing by as much as 10 percent by the end of the century, the study says. While soot blowing in from wildfires contributes to the problem, it hasn't been driving the change, the study finds. The real culprits are two feedback loops created by the...

Why record-breaking Arctic melting is just the beginning
2016-02-28 18:55:00| Climate Ark Climate Change & Global Warming Newsfeed
Independent: Rapidly disappearing Arctic sea ice is about to set a new record after an absurdly warm winter at the top of the world. For the second year running, it will have grown to cover less of the Arctic Ocean than ever before. The revelation comes as scientists are increasingly worried that the heating of the region could escalate out of control, as growing numbers of feedback mechanisms which reinforce and accelerate the process are being discovered. Most attention on the melting sea ice...
