Arctic undergoing holistic climate-change response
From glaciers to caribou, rivers to roads, Arctic climate change is having a broad effect on almost every aspect of life in the North. view more (2005-10-31)
Alaska Space Grant program launches B.E.A.R.
The Alaska Space Grant Program and the Arctic Amateur Radio Club formed the Balloon Experiment And Research Program-or B.E.A.R. for short-in December 2007. view more (2008-06-04)
Researchers establish common seasonal pattern among bacterial communities in Arctic rivers
New research on bacterial communities throughout six large Arctic river ecosystems reveals predictable temporal patterns, suggesting that scientists could use these communities as markers for monitoring climate change in the polar regions. view more (2009-11-24)
Unexplored Arctic region to be mapped
A scientific expedition this fall will map the unexplored Arctic seafloor where the U.S. and Canada may have sovereign rights over natural resources such as oil and gas and control over activities such as mining. view more (2008-09-03)
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)
Record cold winter may increase ozone hole over North Europe
European scientists confirmed that Arctic high atmosphere is reaching the lowest ever temperatures this winter, warning that destruction of the protective ozone layer is substantially increased under very cold conditions. First signs of ozone loss have already been detected. The ozone layer is located in the so called stratosphere, the... view more... (2005-01-31)
Arctic marine mammals on thin ice
The loss of sea ice due to climate change could spell disaster for polar bears and other Arctic marine mammals. The April Special Issue of Ecological Applications examines such potential effects, puts them in historical context, and describes possible conservation measures to mitigate them. view more (2008-04-24)
Are Ice Age relics the next casualty of climate change?
The Wildlife Conservation Society (WCS) recently launched a four-year study to determine if climate change is affecting populations of a quintessential Arctic denizen: the rare musk ox. view more (2008-04-25)
Global warming plus natural bacteria could release vast carbon deposits currently stored in Arctic soil
Increasing concentrations of carbon dioxide in the atmosphere will make global temperatures rise. By studying soil cores from the Arctic, scientists have discovered that this rise in temperature stimulates the growth of microorganisms that can break down long-term stores of carbon, releasing them into the atmosphere as carbon dioxide. This will... view more... (2005-05-05)
Arctic sea ice decline may trigger climate change cascade, says University of Colorado study
Arctic sea ice that has been dwindling for several decades may have reached a tipping point that could trigger a cascade of climate change reaching into Earth's temperate regions, says a new University of Colorado at Boulder study. view more (2007-03-16)
Arctic soil reveals climate change clues
Frozen arctic soil contains nearly twice the greenhouse-gas-producing organic material as was previously estimated, according to recently published research by University of Alaska Fairbanks scientists. view more (2008-10-08)
CU-Boulder researchers forecast 3-in-5 chance of record low Arctic sea ice in 2008
New University of Colorado at Boulder calculations indicate the record low minimum extent of sea ice across the Arctic last September has a three-in-five chance of being shattered again in 2008 because of continued warming temperatures and a preponderance of younger, thinner ice. view more (2008-05-01)
NASA data show Arctic saw fastest August sea ice retreat on record
Following a record-breaking season of arctic sea ice decline in 2007, NASA scientists have kept a close watch on the 2008 melt season. Although the melt season did not break the record for ice loss, NASA data are showing that for a four-week period in August 2008, sea ice melted faster during that period than ever before. view more (2008-09-29)
Ice-Free Arctic Summers Likely Sooner Than Expected
Summers in the Arctic may be ice-free in as few as 30 years, not at the end of the century as previously expected. The updated forecast is the result of a new analysis of computer models coupled with the most recent summer ice measurements. view more (2009-04-03)
Warm winter also in the Arctic
Central Europe is not the only place where the past, warm winter has caused record temperatures. Unusually mild temperatures also prevented ice formation in the Arctic, specifically in the region around Spitsbergen. view more (2007-03-30)
Researchers say Arctic sea ice still at risk despite cold winter
Using the latest satellite observations, NASA researchers and others report that the Arctic is still on "thin ice" when it comes to the condition of sea ice cover in the region. A colder-than-average winter in some regions of the Arctic this year has yielded an increase in the area of new sea ice, while the older sea ice that lasts for... view more... (2008-03-19)
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...

Will an ozone hole develop over the Arctic? A press briefing at the research site
The Theseo presentation will mark the beginning of a decisive period in the development of the Arctic stratosphere. Over the last ten years or so, cold winters have been a prerequisite for maximum ozone depletion, and scientists now understand the chemical processes in the stratosphere that cause the phenomenon. It has been very cold during... view more... (2000-01-21)
Arctic expeditions find giant mud waves, glacier tracks
Scientists gathering evidence of ancient ice sheets uncovered a new mystery about what's happening on the Arctic sea floor today. Sonar images revealed that, in some places, ocean currents have driven the mud along the Arctic Ocean bottom into piles, with some "mud waves" nearly 100 feet across. view more (2007-12-13)
Subtropical Arctic
The North Pole, synonymous with all things very cold, once had a subtropical climate according to scientists now returning from the Arctic . view more (2004-09-06)
