Less summer Arctic sea ice cover means colder, snowier winters in Central Europe
ScienceDaily.com | 01 Feb 2012
Even if the current weather situation may seem to go against it, the probability of cold winters with a lot of snow in Central Europe rises when the Arctic is covered by less sea ice in summer.

Canadian seal cull 'unnecessary due to climate change'
Guardian Unlimited | 06 Jan 2012
Canada faced fresh calls to shut down its commercial seal hunt on Thursday, following new evidence that death rates among seal pups had dramatically increased due to thinning winter sea ice.

Increasingly precise data on radiation reflected from the Arctic sea area
ScienceDaily.com | 07 Oct 2011
Scientists have developed a new, globally unique method for estimating surface albedo in the Arctic sea area solely on the basis of microwave data. Its advantage over conventional optical methods is that neither clouds nor darkness interfere with measurements.

Arctic sea ice continues decline, hits second-lowest level
ScienceDaily.com | 05 Oct 2011
Last month the extent of sea ice covering the Arctic Ocean declined to the second-lowest extent on record. Satellite data from NASA and the the National Snow and Ice Data Center showed that the summertime sea ice cover narrowly avoided a new record low. The near-record ice-melt followed higher-than-average summer temperatures, but without the unusual weather conditions that contributed to the extreme melt of 2007.

Melting ice is Earth's warning signal - and we cannot ignore it
Guardian Unlimited | 24 Sep 2011
Ice is the white flag being waved by our planet, under fire from the atmospheric attack being mounted by humanity. From the frosted plains of the Arctic ice pack to the cool blue caverns of the mountain glaciers, the dripping away of frozen water is the most crystal clear of all the Earth's warning signals.

The reversibility of sea ice loss in a state-of-the-art climate model
American Geophysical Union | 23 Sep 2011
Rapid Arctic sea ice retreat has fueled speculation about the possibility of threshold (or tipping point) behavior and irreversible loss of the sea ice cover. We test sea ice reversibility within a state-of-the-art atmosphere–ocean global climate model by increasing atmospheric carbon dioxide until the Arctic Ocean becomes ice-free throughout the year and subsequently decreasing it until the initial ice cover returns.

Arctic sea ice is melting at its fastest pace in almost 40 years
Guardian Unlimited | 11 Sep 2011
The Northwest Passage was, again, free of ice this summer and the polar region could be unfrozen in just 30 years Arctic sea ice has melted to a level not recorded since satellite observations started in 1972 - and almost certainly not experienced for at least 8,000 years, say polar scientists.

Experts drill Arctic ice to fathom speed of melt
Reuters | 07 Sep 2011
500 MILES OFF THE NORTH POLE (Reuters) - As polar bears stalked their ship, scientists drilled into the Arctic sea ice this week to try and figure out why it's disappearing so fast.

Rowers first to reach magnetic North Pole
New Zealand Herald | 28 Aug 2011
A six-man British crew have become the first to row to the magnetic North Pole, completing the 725km journey from northern Canada in under four weeks. Crew leader Jock Wishart undertook the expedition to highlight climate change in the Arctic region.

Pacific walruses studied as sea ice melts
ScienceDaily.com | 25 Aug 2011
U.S. Geological Survey Alaska Science Center researchers, in cooperation with the Native Village of Point Lay, will attempt to attach 35 satellite radio-tags to walruses on the northwestern Alaska coast in August as part of their ongoing study of how the Pacific walrus are responding to reduced sea ice conditions in late summer and fall.
