These findings will help scientists understand the consequences of the rapidly changing Arctic climate
and could provide important clues to understand the changes in the polar ecosystem, said NASA (http://www.nasa.gov/topics/earth/features/ocean-bloom.htmlhttp:/news.yahoo.com/nasa-discovers-unprecedented-blooms-ocean-plant-life-181805518.html;_ylt=A2KJ3CY5.tBP8zkAquLQtDMD) in a press release.
A key component of the Arctic climate
clockworks is the Beaufort Gyre--a bowl of cold, icy, relatively fresh waters north of Alaska that is swept by prevailing winds into a circular swirl larger than the Gulf of Mexico.
Given this effect, if shrubs replace extensive areas of grass-covered tundra, the overall Arctic climate
could undergo a major transformation, Sturm and his colleagues suggest.
Regionally, Terry Fenge celebrates four long years of work by some 300 scientists who have broken new ground with their Arctic Climate
Impact Assessment that looks at the health and culture of Arctic peoples.
The Arctic Climate
Impact Assessment [Environmental Intelligence, January/February 2005] already documented the Arctic-warming effect in cold-climate species.
The Arctic Climate
Impact Assessment (ACIA), published on November 8, concludes that the Arctic is warming twice as quickly as the rest of the planet, and that the ice cap may totally disappear during the Summer months by 2100, threatening the survival of thousands of animal species and overturning the traditional way of life of indigenous peoples.
The harsh Arctic climate
-- winter temperatures of -40 are common -- took its toll and the roof was leaking and floor listing noticeably when a Hamilton, Ont., man named Chris Robertson bicycled into town in October 1997.
While some of the metal instrumentation didn't survive the cold, humid environment, other items like paper documents were well preserved by the Arctic climate
. The artifacts were sent to the city of Arkhangelsk in northern Russia, and an exhibition was planned for later in the year to share with the public.

change as this remote phenomenon that has little effect on our everyday lives," Charles H.
