Arctic Amplification Has Reduced Risk Of Extreme Cold Weather
2014-06-16 04:41:53

redOrbit Staff & Wire Reports - Your Universe Online Despite the fact that many parts of the United States experienced extremely cold conditions this past winter, the risk of such conditions increasing as a result of climate change is unlikely, according to research appearing in the latest edition of Nature Climate Change. Study author Dr. James Screen of the University of Exeter reports that the Arctic amplification phenomenon, which refers to the increased warming rate experienced...

Arctic Ice Improving
2013-12-16 15:27:28

Lee Rannals for redOrbit.com - Your Universe Online The European Space Agency’s (ESA) CryoSat satellite has delivered some good news about the Arctic sea ice this fall. New measurements taken by CryoSat show the volume of Arctic sea ice has significantly increased this fall, rising by about 50 percent compared to last year. Satellites have been showing a downward trend in the area of Arctic Ocean covered by ice over the past few decades, so the latest measurements are much welcomed news....

Long-term Data Reveal Deep Greenland Sea Warming Faster Than The Global Ocean
2013-09-25 12:53:48

Alfred Wegener Institute Recent warming of the Greenland Sea Deep Water is about ten times higher than warming rates estimated for the global ocean. Scientists from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research recently published these findings in the journal Geophysical Research Letters. For their study, they analyzed  temperature data from 1950 to 2010 in the abyssal Greenland Sea, which is an ocean area located just to the south of the Arctic Ocean....

Arctic Sea Ice Political Controversy
2013-09-09 10:50:24

Brett Smith for redOrbit.com - Your Universe Online Instead of providing a sneak-peek into cutting-edge climate research, a recently leaked UN report on Arctic sea ice has mostly provided insight into the political divide surrounding the contentious issue of global warming. Two of the UK’s supposedly more conservative periodicals, the Daily Mail and The Telegraph, seized on the leaked report’s finding that Arctic sea ice was 60 percent larger in August 2013 compared to August 2012....

Sea Ice Decline Changing The Vegetation Of The Arctic
2013-08-23 10:26:03

Geophysical Institute, University of Alaska Fairbanks Sea ice decline and warming trends are changing the vegetation in nearby arctic coastal areas, according to two University of Alaska Fairbanks scientists. Uma Bhatt, an associate professor with UAF’s Geophysical Institute, and Skip Walker, a professor at UAF’s Institute of Arctic Biology, contributed to a recent review of research on the response of plants, marine life and animals to declining sea ice in the Arctic. “Our...

A new paper co-written by UM associate professor Mark Hebblewhite details ecological changes caused by a loss of Arctic sea ice. The paper concludes that the loss of sea ice obviously will impact the marine food web and the marine mammals that depend on sea ice habitat. Other major ecological changes in adjacent land-based habitats and species also will occur because of warming oceans. The findings were published in the Aug. 2 issue of Science magazine. Wildlife species like the polar...

New research by UM bioclimatology Assistant Professor Ashley Ballantyne models the influence of Arctic sea ice on Arctic temperatures during the Pliocene era. His research was published in the Research Highlight section of the July issue of Nature Geoscience. The full paper will be published in Palaeogeography, Palaeoclimatology, Palaeoecology: An International Journal for the Geosciences. Ballantyne and coauthors from Northwestern University, the University of Colorado and the National...

There is growing recognition that reductions in Arctic sea ice levels will influence patterns of atmospheric circulation both within and beyond the Arctic. New research in the International Journal of Climatology explores the impact of 2007 ice conditions, the second lowest Arctic sea ice extent in the satellite era, on atmospheric circulation and surface temperatures. Two 30-year simulations, one using the sea ice levels of 2007 and another using sea ice levels at the end of the 20th...

Researchers Predict Sea Ice-Free Arctic Summers By 2050
2013-04-13 08:18:46

April Flowers for redOrbit.com — Your Universe Online The question of ice-free summers in the Arctic, for most scientists, is not "if," but "when." A new study by two National Oceanic and Atmospheric Administration (NOAA) scientists says that "when" is coming sooner than many thought. Already, the Arctic has experienced a loss of thick, multi-year ice, with last September´s extent being less than half the average of 1979-2000. The scientists, James Overland...

Climate Change Affecting Polar Bears, Only Those With The Most Fat Thrive
2013-03-20 14:36:52

Brett Smith for redOrbit.com - Your Universe Online Recent climate induced changes to Arctic polar bears´ environment is affecting their habits and ability to survive, with the bears having to rely more and more on internal fat reserves, according to a new paper in the Journal of Animal Ecology. The bears are having particular difficulty adjusting to the shifting sea ice dynamics. In the past, sea ice has remained throughout the Arctic summer months, but now it is almost...
