The Arctic is getting warmer and wetter. As temperatures rise and sea ice melts, scientists suspect that system feedback cycles may further speed up the warming process.

Polar Bear Researcher Cleared Of Scientific Misconduct

The scientist who helped bring the plight of the polar bear to the public's attention and helped get the creatures listed as a threatened species has been reprimanded by federal investigators.

Marine scientists from Kiel, together with colleagues from Bremen, Great Britain, Switzerland and Norway, spent four and a half weeks examining methane emanation from the sea bed off the coast of Spitsbergen with the German research vessel MARIA S. MERIAN. There they gained a very differentiated picture: Several of the gas outlets have been active for hundreds of years.

Arctic Ice Reaches Least Extent Since 2007 Summer Season

The Arctic sea ice has stopped receding this year, but not before reaching its smallest extent, breaking the previous record set in the summer of 2007, by 18 percent.

Climate Change Shrinking Sea Ice, Seal Species Threatened
2012-09-17 15:49:26

Scientists reported in the journal Geophysical Research Letters that the ringed seal is being threatened by shrinking sea ice in the Arctic.

Arctic Crustaceans Survive Ice Melt By Migrating Via Deep Ocean Currents

Sometime between 200 and 500 years ago, in the throes of a mini ice age, sea ice had become thick and stable enough for animal migration to occur between regions in far northern Europe.

Arctic Sea Ice Loss Could Have Major Impacts
2012-09-10 06:24:56

As the end of the Arctic melt season ends with the region having already set new records for the smallest amount of sea ice extent and volume, experts this past weekend began to gauge exactly what the implications will be, both locally and throughout the rest of the world.

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...
