Satellites witness lowest Arctic ice coverage in history
The area covered by sea ice in the Arctic has shrunk to its lowest level this week since satellite measurements began nearly 30 years ago, opening up the Northwest Passage - a long-sought short cut between Europe and Asia that has been historically impassable. view more (2007-09-17)
River-shelf interactions during Spring floods in the coastal Beaufort Sea
Multi-year study provides insights to possible future responses to environmental change in the arctic. view more (2006-12-06)
Unstated assumptions color Arctic sovereignty claims
Settling the growing debate over ownership of Arctic Ocean resources is complicated by the fact that the various countries involved have different understandings of the geography of the place. view more (2009-05-29)
Cave Study Links Climate Change to California Droughts
California experienced centuries-long droughts in the past 20,000 years that coincided with the thawing of ice caps in the Arctic. view more (2009-11-11)
Arctic sea ice declines again in 2006, say University of Colorado researchers
While cool August temperatures prevented sea ice in the Arctic from reaching its lowest summer extent on record, 2006 continued a pattern of sharp annual decreases due to rising temperatures probably caused by greenhouse warming. view more (2006-10-05)
Arctic sea ice shatters record low: diminished ice leads to Northwest Passage opening
Arctic sea ice during the 2007 melt season plummeted to the lowest levels since satellite measurements began in 1979, according to researchers at the University of Colorado at Boulder's National Snow and Ice Data Center. view more (2007-10-02)
Global warming could lead to a greener Greenland (embargoed until 18.00 BST)
Research published in Nature suggests that enough greenhouse gases could be in the atmosphere as early as 2050 to melt the massive ice-sheet that covers Greenland. As a result, sea levels could rise by around seven metres over the next 1,000 years. Along with colleagues in Belgium and Germany, Dr Jonathan Gregory, of the Centre for Global... view more...

The Arctic and Global Warming
A warmer Arctic Ocean may mean less food for the birds, fish, and baleen whales and be a significant detriment to that fragile and interconnected polar ecosystem, and that doesn't bode well for other ocean ecosystems in the future. view more (2006-02-21)
Glimpse to past adds weight to global warming forecasts
A new examination of the period of global warming that planet Earth underwent 130,000 years ago is helping scientists to confirm the accuracy of projections for the next century - particularly over Canada's North. view more (2006-03-24)
UNH/NOAA Report: Arctic Region Underprepared for Maritime Accidents
The existing infrastructure for responding to maritime accidents in the Arctic is limited and more needs to be done to enhance emergency response capacity as Arctic sea ice declines and ship traffic in the region increases, according to new report released today by the University of New Hampshire and the National Oceanic and Atmospheric... view more...

Arctic sea ice annual freeze-up underway
After reaching the second-lowest extent ever recorded last month, sea ice in the Arctic has begun to refreeze in the face of autumn temperatures, closing both the Northern Sea Route and the direct route through the Northwest Passage. view more (2008-10-03)
Ecologists use oceanographic data to predict future climate change
Ecologists and oceanographers are attempting to predict the future impacts of climate change by reconstructing the past behavior of Arctic climate and ocean circulation. view more (2008-11-07)
Higher Water Temperatures and Reduced Ice Cover In the Arctic Ocean
Over the past six weeks, scientists aboard the research vessel "Polarstern" of the Alfred Wegener Institute for Polar and Marine Research have been investigating changes in ocean temperature and sea ice cover in the area of Fram Strait between Spitsbergen and Greenland. In this area significant exchange of water masses between the Arctic Ocean... view more... (2004-08-27)
Permafrost Threatened by Rapid Retreat of Arctic Sea Ice, NCAR Study Finds
The rate of climate warming over northern Alaska, Canada, and Russia could more than triple during periods of rapid sea ice loss, according to a new study led by the National Center for Atmospheric Research (NCAR). view more (2008-06-11)
Continued warming of the Arctic Ocean
Several days ago, the 'Maria S Merian' returned from her second Arctic expedition with data confirming trends of Arctic warming. view more (2006-10-05)
New Test of Snow's Thickness May 'Bear' Results Key to Polar Climate Studies, Wildlife Habitat
A NASA-funded expedition to the Arctic to map the thickness of snow has a legion of unexpected furry fans hailing from one of the world's coldest regions: polar bears. view more (2006-03-16)
Erosion rates double along portion of Alaska's coast
Skyrocketing coastal erosion occurred in Alaska between 2002 and 2007 along a 64 kilometer (40 mile) stretch of the Beaufort Sea, a new study finds. The surge of erosion in recent years, averaging more than double historical rates, is threatening coastal towns and destroying Alaskan cultural relics. view more (2009-02-19)
Research team draws 150-meter ice core from McCall Glacier
A 150-meter ice core pulled from the McCall Glacier in the Arctic National Wildlife Refuge this summer may offer researchers their first quantitative look at up to two centuries of climate change in the region. view more (2008-07-11)
Warmer air may cause increased Antarctic sea ice cover
Predicted increases in precipitation due to warmer air temperatures from greenhouse gas emissions may actually increase sea ice volume in the Antarctic's Southern Ocean. view more (2005-06-30)
Warming climate may put chill on arctic polar bear population
Some travel agencies touting Arctic tours have been revving up their recent promotions to tourists about the increased likelihood they will spot polar bears in this region where several populations of polar bears live. view more (2006-09-14)
