As More Arctic Ice Melts, Polar Bears Get Creative to Feed Themselves
2014-01-21 22:32:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World: As warming temperatures change the landscape of the Arctic, polar bears there are showing remarkable resiliency in surviving by changing their diet to accommodate, according to recent research. Historically, polar bears' prey of choice are ringed seal pups. But as a warming climate causes Arctic sea ice to melt quicker each year, it limits hunting opportunities for polar bears, who venture out on the ice in search of prey. A group of researchers from the American Museum of Natural History observed...

Increased Mercury Levels In Arctic Ice Found Pushing Into Sea Water
2014-01-16 19:18:00| Climate Ark Climate Change & Global Warming Newsfeed
RedOrbit: Researchers Dr. Chris Moore and Dr. Daniel Obrist, from Nevada`s Desert Research Institute, have recently discovered an increased level of mercury in Arctic sea ice. The study, published in the journal Nature, also found that the element is contaminating sea water below. The researchers claim that the air above large cracks found in the ice of the Arctic is mixing vigorously pushing mercury down to the exposed seawater. This process causes an increase in toxic levels, which can in turn enter into...
Sea Ice Cracks Causing Mercury Buildup in Arctic Air
2014-01-15 21:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Climate Central: Arctic sea ice has been retreating at an alarming rate due to climate change. Its loss has decreased habitat for species such as the polar bear, created problems for Arctic communities, and may even be affecting weather patterns outside the region. New research published in Nature on Wednesday adds another impact to the list, suggesting that cracks in the ice are affecting complex chemical processes in the atmosphere and causing more mercury to find its way into the region's ecosystems. The research...
Underestimating global warming: gaps in Arctic temperature data lead scientists and public astray
2014-01-15 17:17:00| Climate Ark Climate Change & Global Warming Newsfeed
Mongabay: pen question due to large gaps in temperature data across the vast region. Now, a recent study in the Quarterly Journal of the Royal Meteorological Society finds that not only is the Arctic warming eight times faster than the rest of the planet, but failure to account for temperature gaps has led global datasets to underestimate the rise of temperatures worldwide. Recently, some scientists have noted that the pace of global warming appears to have slowed-while many climate change deniers and media...
Antarctica & the Arctic: A polar primer for the new great game
2014-01-13 15:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Christian Science Monitor: Just after noon on Sept. 4, 2010, a squat, yellow-black cargo ship lumbered out of the Norwegian port of Kirkenes. Naked ridges of glacially scarred granite slid by on either side as the Nordic Barents motored toward the open sea with 41,000 tons of iron ore locked in her belly. It might have resembled a routine voyage to Western Europe. But the sense of normalcy vanished as the ship reached the mouth of the fiord, a geographic and economic crossroads at the extreme northern edge of Scandinavia....
