Arctics Rapid Sea Ice Loss Threatens Wildlife
2013-08-11 14:30:00| Climate Ark Climate Change & Global Warming Newsfeed
Climate News Network: The loss of Arctic sea ice is bad news for the Pacific walrus, and for polar bears: the walrus has further to swim to dig for clams on the sea floor, and the polar bear has less chance of catching seals. But the real problems begin at the base of the food chain. Since the end of the last century, more than two million square kilometers of sea ice have disappeared, and the loss of summer ice is accelerating. Researchers call this "a stunning loss of habitat for sea ice algae and sub-ice plankton...
Scientists mull Arctics slow CO2 loss
2013-07-30 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Climate News Network: The Arctic permafrost thaws each year, but to the surprise of scientists from Denmark in some areas it is not releasing the carbon dioxide it contains nearly as fast as they had expected. LONDON, 28 July Think of permafrost as a slush fund of so-far uncertain value. The levels of Arctic permafrost that thaw each year and freeze again are growing at depths of 1cm a year, but the carbon locked away in the soils is so far not being released at an accelerating rate. This is good news for...

Arctics Boreal Forests Burning At Unprecedented Rate
2013-07-22 23:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Climate Central: In a sign of how swiftly and extensively climate change is reshaping the Arctic environment, a new study has found that the region's mighty boreal forests -- stands of mighty spruce, fir, and larch trees that serve as the gateway to the Arctic Circle -- have been burning at an unprecedented rate during the past few decades. The study, published Monday in the Proceedings of the National Academy of Sciences, found that the boreal forests have not burned at today's high rates for at least the past 10,000...

Charting the Arctics future with logbooks from the past
2013-04-10 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Climate Central: Figuring out the future of the rapidly warming Arctic is crucial for climate scientists, largely because changes in the region's ice -- both on land and at sea -- can have major consequences for the rest of the planet. Sea ice declined to a record low in September 2012, and scientists have projected that the region will become seasonally ice-free by mid-century, based on satellite data, observational evidence, and other information. But researchers have only recently had the ability to keep close...

Norway's Oil Future Seen With Ice-Free Arctic's Barrels: Energy
2013-04-04 17:47:06| Appliances - Topix.net
In the wake of plummeting oil output, Norway, western Europe's biggest petroleum producer, may have found its new money spigot: an ice-free expanse of the Arctic Ocean known as the Barents Sea.
