Warming Arctic Climate Turns Shrubs To Forests
2012-06-05 03:52:51

Plants and shrubs in the Arctic tundra have turned into small trees in recent decades due to the warming Arctic climate. If the trend continues on a wider scale, it would significantly accelerate global warming, said scientists from Finland and Oxford University in a new study published in the journal Nature Climate Change. The researchers investigated an area of 100,000 square kilometers from western Siberia to Finland known as the northwestern Eurasian tundra. Surveys of the area´s...

As Canada prepares to chair the Arctic Council, Munk-Gordon Arctic Security Program offers 19 recommendations based on international workshop in January Finding a new way to fund the full participation of northern indigenous groups with Permanent Participant status at the Arctic Council in all of the organizations working groups and activities should be a top priority when Canada takes the chair of the influential inter-governmental organization next year. The recommendation is one of...

Circumpolar Rivers Most Responsible For High Levels Of Mercury In The Arctic
2012-05-23 04:17:55

Brett Smith for RedOrbit.com If global warming trends are to continue, thermometers across the globe aren´t the only place that mercury levels will be on the rise. The concentration of mercury in the Arctic environment is directly related to forces associated with climate change, according to a new study from Harvard University researchers. Both atmospheric forces and the flow of circumpolar rivers carry the toxic metal north into the Arctic Ocean, but it turns out that the...

Thawing Arctic Cryosphere Releases Trapped Methane
2012-05-22 09:10:29

Brett Smith for RedOrbit.com The edges of glaciers and Arctic permafrost are where most of the evidence of global warming can be seen, but scientists have recently been traveling to these remote locations for a different reason. Researchers from the University of Alaska at Fairbanks just published a study in the online edition of Nature Geoscience showing that methane trapped under arctic lake ice for millions of years is now being released by the melting ice. The team used both aerial...

Latest CryoSat Results Revealed
2012-04-25 01:09:22

After nearly a year and a half of operations, CryoSat has yielded its first seasonal variation map of Arctic sea-ice thickness. Results from ESA´s ice mission were presented Tuesday at the Royal Society in London. In June 2011, the first map of Arctic sea-ice thickness was unveiled, using CryoSat data acquired between January and February of that year. Now, the complete 2010—11 winter season data have been processed to produce a seasonal variation map of sea-ice thickness....

Scientists Concerned About Methane, Fishing In Arctic Ocean
2012-04-23 04:04:47

While some scientists encouraged the creation of regulations governing fishing in the Arctic Ocean on Sunday, others published a report warning that the body of water could actually be a significant source of the greenhouse gas methane. The latter team, lead by Eric Kort of the California Institute of Technology (Caltech), participated in a total of five flights to measure atmospheric methane levels in latitudes as high as 82 degrees north in 2009 and 2010, AFP reporters said. They...

Ocean Found To Be Surprising Source Of Arctic Methane
2012-04-23 03:49:05

The fragile and rapidly changing Arctic region is home to large reservoirs of methane, a potent greenhouse gas. As Earth's climate warms, the methane, frozen in reservoirs stored in Arctic tundra soils or marine sediments, is vulnerable to being released into the atmosphere, where it can add to global warming. Now a multi-institutional study by Eric Kort of NASA's Jet Propulsion Laboratory, Pasadena, Calif., has uncovered a surprising and potentially important new source of Arctic methane:...

The idea that the Arctic is changing is not breaking news. Sea-ice extent has been declining by 12 percent per decade since 1979, and the ice is thinning too. Because of this, new shipping routes are becoming accessible during the summer months, and the Arctic is beginning to attract parties interested in resource exploration, scientific research and tourism. Therefore, a more accessible Arctic not only means environmental changes, but also changes in our economy and our national security....

Study examined blood level changes in PCBs over a decade It's never been easy to be a polar bear. They may have to go months without eating. Their preferred food, seal, requires enormous luck and patience to catch. Add to that the melting of Arctic sea ice due to climate change, and the poisoning of the Arctic by toxic chemicals, and it's easy to see why polar bears worldwide are in trouble. Among all the bad news, however, comes one possible bright spot. In a study of PCBs in polar...

Alaskan Hare, Lepus othus
2014-05-19 10:40:26

The Alaskan hare (Lepus othus), or the tundra hare, can be found on the Alaskan Peninsula and in western areas of Alaska. This species prefers to reside in rocky areas in their tundra habitat, resting in open areas rather than in burrows. It is most closely related to the mountain hare and the Arctic hare. Members of this species reach an average weight between 1.6 and 2.2 feet, with hind feet that reach a length of 7.9 inches. The hind feet are thought to help the hares move quickly and...

Arctic Ocean

The Arctic Ocean which is located in the Northern Hemisphere and mostly in the Arctic north polar region, is the shallowest and smallest of the world’s five major oceanic divisions. The International Hydrographic Organization recognizes it as an ocean, although, some oceanographers consider it as the Arctic Mediterranean Sea or simply, the Arctic Sea, classifying it a Mediterranean sea or an estuary of the Atlantic Ocean. Alternatively, the Arctic Ocean can be considered as the northernmost...

Continental arctic air mass is known for its very frigid and dry air. The most common place in the United States to find this air mass is in Alaska. However, in the coldest parts of the winter such as December and January along with early February it is not uncommon for this air mass to invade the Northern part of the United States. This air mass is responsible for bringing with it temps that drop well below zero. Along with the cold temps the air is very dry and if people stay outside in...

Arctic haze is a phenomenon that occurs in the atmosphere at high latitudes in the Arctic due to air pollution. What distinguishes Arctic haze from haze found elsewhere, is the ability of its chemical ingredients to endure in the atmosphere for a longer period of time compared to other pollutants. Due to limited snowfall, rain, or turbulent air to displace pollutants from the polar air in the spring, Arctic haze can continue for more than a month in the northern atmosphere. Arctic haze was...

The Common Redpoll (Carduelis flammea), is a species in the finch family. It breeds throughout northern North America and Eurasia. Subspecies of the Common Redpoll include the Arctic Redpoll and Mealy Redpoll. These are common too in the Arctic, Iceland, Greenland, and Baffin Island. They all migrate south into southern Canada, northern United States and most of Eurasia. These birds are remarkably resistant to cold temperatures and winter migration is mainly due to lack of food rather...
