Humans Not Main Culprit in Musk Ox Population Decline After Last Ice Age
10.03.2010
A team of scientists found that human activity is not the reason behind the drastic decline in Arctic musk ox populations that began 12,000 years ago. The findings, to be published in the journal Proceedings of the National Academy of Sciences (PNAS), shows that while both human and musk ox…

Stores of Methane in Arctic Seabed Being Released into Atmosphere
08.03.2010
New results from an international study published in the journal Science show that the permafrost under the East Siberian Arctic Shelf is perforated and releasing huge amounts of methane, a powerful greenhouse gas, into the atmosphere. Three times as large as the Siberian wetlands, the East Siberian Arctic Shelf is…

Can Polar Bears Survive Rapid Change in Climate Again?
04.03.2010
A team of scientists was able to determine that the polar bear is a relatively new species that rapidly adapted at a time when the Earth was beginning to warm at the end of an ice age, according to a new study published in the Proceedings of the National Academy…

Glacier Ice Loss in Alaska Overestimated; Rate Nonetheless Doubled over Past 40 Years
04.03.2010
According to a new study featured in Nature Geoscience that recalculates glacier melt in Alaska, previous studies might have largely overestimated mass loss from Alaskan glaciers over the past 40 years. The study shows that Alaskan glacier melts between 1962 and 2006 actually contributed about one-third less to sea-level rise…

Weak Ice Arches Allowing Sea Ice to Leave Arctic
02.03.2010
Large chunks of ice that clump together to form ice arches spanning the straits that lead out of the Arctic Ocean usually prevent the ice from moving around and fleeing the ocean. In recent years, however, these ice arches have been failing to form. The consequences of the resulting sea…
