Arctic is Getting Darker, Absorbing More Heat; Study Finds
2014-02-18 15:32:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World News: The North Pole has gotten darker in the past few years due to sea ice loss. The rapid melting of sea ice in Arctic has resulted in the region trapping more heat than before, according to a new study. The present study by researchers at Scripps Institution of Oceanography in California and colleagues used three decades' worth of satellite data and found that arctic darkening was two or three times more than previous estimates, Associated Press reported. Explaining Arctic darkening, Ian Eisenman,...
Darker Arctic boosting global warming
2014-02-17 22:52:00| Climate Ark Climate Change & Global Warming Newsfeed
Associated Press: The Arctic isn't nearly as bright and white as it used to be because of more ice melting in the ocean, and that's turning out to be a global problem, a new study says. With more dark, open water in the summer, less of the sun's heat is reflected back into space. So the entire Earth is absorbing more heat than expected, according to a study published Monday in the Proceedings of the National Academy of Sciences. Melting Arctic ice called economic time bomb That extra absorbed energy is so...

Warming from Arctic Sea Ice Melting More Dramatic than Thought
2014-02-17 21:25:00| Climate Ark Climate Change & Global Warming Newsfeed
LiveScience: Melting Arctic sea ice has contributed considerably more to warming at the top of the world than previously predicted by climate models, according to a new analysis of 30 years of satellite observations. Sea ice helps cool the Arctic by reflecting incoming solar radiation back into space. Because of its light color, sea ice has what is known as high albedo, which is the percentage of solar radiation a surface reflects back to space. Dark ocean water left behind by melting sea ice, on the other...
Warming Arctic May Be Causing Jet Stream Lose Its Way

National Public Radio: Mark Twain once said: "If you don't like the weather in New England now, just wait a few minutes." He was making an unknowing reference to the jet stream, which drives the weather over North America and Europe like a high-altitude conveyor belt. But increasingly, the jet stream is taking a more circuitous route over the northern latitudes, meaning weather systems hang around longer than they used to. And, a warming Arctic is probably to blame, says Jennifer Francis, a professor at Rutgers University's...
Rapidly warming Arctic may be causing polar-vortex winter
2014-02-16 15:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Toronto Star: The rapidly warming Arctic may be behind persistent weather patterns half a world away, including our polar-vortex winter, the U.K.s relentless rain, and droughts in the American southwest, according to a controversial new theory. Persistent weather isnt just annoying, as the months-long, life-numbing chill has been. It can also be destructive. If it doesnt rain for a few days, no big deal. But if it goes on for weeks, it becomes a big deal, said Jennifer Francis, a Rutgers University...
