Plugging an ozone hole: Extreme Antarctic ozone holes have not been replicated in Arctic

Posted by External 21 hours ago General
http://feeds.sciencedaily.com — Since the discovery of the Antarctic ozone hole, scientists, policymakers, and the public have wondered whether we might someday see a similarly extreme depletion of ozone over the Arctic. But a new study finds some cause for optimism: Ozone levels in the Arctic haven’t yet sunk to the extreme lows seen in Antarctica, in part because international efforts to limit ozone-depleting chemicals have b Read More

NASA study finds Arctic melt is now 15 days longer than 30 years ago

Posted by External 8 days ago General
http://www.enn.com — The length of the melt season for Arctic sea ice is growing by several days each decade, and an earlier start to the melt season is allowing the Arctic Ocean to absorb enough additional solar radiation in some places to melt as much as four feet of the Arctic ice cap’s thickness, according to a new study by National Snow and Ice Data Center (NSIDC) and NASA researchers.

The Melting Arctic

Posted by External 10 days ago General
http://www.enn.com — As the Eastern US ends what seems to have been the most severe winter in memory, it is hard to remember that the global climate is still warming. A severe winter in a region doesn't mean that the entire hemisphere had an extreme winter. And it really doesn't imply much about long term trends. A key indicator of long term trends is the length of the Arctic melt season. Read More

Dynamics behind Arctic ecosystems revealed

Posted by External 18 days ago General
http://feeds.sciencedaily.com — Species such as the musk ox, Arctic fox and lemming live in the harsh, cold and deserted tundra environment. However, they have often been in the spotlight when researchers have studied the impact of a warmer climate on the countryside in the north. Until now, the focus has been concentrated on individual species, but an international team of biologists has now published an important study of ent Read More

Seasonal Arctic summer ice extent still hard to forecast, study says

Posted by External 18 days ago General
http://feeds.sciencedaily.com — Scientists analyzed 300 summer Arctic sea ice forecasts from 2008 to 2013 and found that forecasts are quite accurate when sea ice conditions are close to the downward trend that has been observed in Arctic sea ice for the last 30 years. However, forecasts are not so accurate when sea ice conditions are unusually higher or lower compared to this trend. Read More
