Latest Arctic Stories
Researchers from UCLA claim the unprecedented late summer ice melt due to widespread climate change will make the Arctic Ocean shipping lanes more accessible by the year 2050.
The US government and the polar bear won an important court ruling on Friday, as an appeals court deemed that the Bush administration had acted reasonably when they decided to list the Arctic mammal as a “threatened” species under the Endangered Species Act due to the effects of climate change.
February 27 is International Polar Bear Day, sponsored and led by Polar Bear International. This special day is meant to raise awareness of the bear's plight, and the damage that humans are inflicting with global warming.
Can existing ecological communities persist intact as temperatures rise? This is a question of increasing relevance in the field of climate change and is the focus of a new study to be published in the journal Proceedings of the Royal Society of London on 20 February.
According to research from Lund University in Sweden, the widespread reduction of ice in the Arctic Ocean has disrupted the balance of greenhouse gases in the region.
New observations using satellites have confirmed University of Washington researchers' analysis the Arctic Ocean sea ice really is thinning.
An international group of scientists, led by a University of Alberta polar bear researcher, is urging governments to prepare for rapid Arctic ecosystem change to deal with a climate change catastrophe for the polar bears.
A 21-page document aiming to help with oil spill plans in the Arctic Ocean is apparently not good enough, according to environmentalists, who add the guidelines are vague and do not define corporate liability over such accidents.
Researchers are disputing the theory that the culprit behind the historic sea ice minimum was "The Great Arctic Cyclone of August 2012."
Scientists have known that climate change affects the population dynamics of single species, such as reindeer or caribou, but the effects of such climate change at the community level have been much harder to document and quantify.
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...
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...
