But this, Streletskiy said, "is not really a sustainable solution" for most Arctic infrastructure.

Most Arctic bases would struggle to contain an infection that spreads the way the coronavirus does.

Given that most Arctic Council members are also NATO allies, the defense alliance has a vested interest in keeping tensions low in the high north.

That means Obama's indefinite ban on drilling in most Arctic waters and parts of the Atlantic Ocean will remain in place until they're revoked by Congress.

Russia is the most Arctic of countries, controlling 2000 percent of the land area above the Arctic Circle and home to three-quarters of the polar region's population.

The buildings also burned 12.2 percent less natural gas because less overchilling reduced the amount of air that had to be reheated in the buildings' most arctic zones.

Governments agreed at the 2015 Paris Accord to cap emissions enough to limit global warming to 1.5 degree Celsius above pre-industrial levels after which global warming is expected to have extreme consequences that will all but wipe out the world's coral reefs and most Arctic sea ice.

Governments agreed at the 2015 Paris Accord to cap fossil fuel emissions enough to limit global warming to 1.5 Celsius (2.7 Fahrenheit) above pre-industrial levels - after which global warming is expected to be so severe that it will all but wipe out the world's coral reefs and most Arctic sea ice.

Noatak, Alaska, 1929 - by Edward S. Curtis Iñupiat people are hunter-gatherers, as are most Arctic peoples. Iñupiat people continue to rely heavily on subsistence hunting and fishing. Depending on their location, they harvest walrus, seal, whale, polar bears, caribou, and fish. Both the inland (Nunamiut) and coastal (Taġiumiut, i.e.

Permafrost is soil which has been frozen for two or more years. In most Arctic areas it is from a few to several hundred metres thick. Permafrost thawing may be a serious cause for concern. It is believed that carbon storage in permafrost globally is approximately 1600 gigatons; equivalent to twice the atmospheric pool.

While both types also haul barges, the cargo ship also carries cargo on deck. Most Arctic communities do not have a port and cranes to unload the supplies but may have a simple dock. Where the community does not have a dock, the ship either must ground itself or the barges. Supplies are then removed by forklift truck which is also carried on board.

They lived primarily by hunting sea mammals and were capable of taking animals as large as walrus and narwhal. About 500 BC they moved down the Labrador coast and occupied the island of Newfoundland for about 1000 years. About 1000 AD they were displaced from most arctic regions by an invasion of Thule Inuit from Alaska, but they continued to live in northern Québec and Labrador until approximately 1500 AD.

Compared to the Antarctic, where there is no major surface predator, Arctic seals use more breathing holes per individual, appear more restless when hauled out on the ice, and rarely defecate on the ice. The baby fur of most Arctic seal species is white, presumably to provide camouflage from predators, whereas Antarctic seals all have dark fur at birth. Brown bears tend to dominate polar bears in disputes over carcasses,O'Harra, Dough (24 April 2005) Polar bears, grizzlies increasingly gather on North Slope. Anchorage Daily News.

This dead bone structure is the mature antler. In most cases, the bone at the base is destroyed by osteoclasts and the antlers fall off at some point. As a result of their fast growth rate, antlers are considered a handicap since there is an immense nutritional demand on deer to re-grow antlers annually, and thus can be honest signals of metabolic efficiency and food gathering capability. Increasing size of antlers year on year in different European game species, 1891 illustration In most arctic and temperate-zone species, antler growth and shedding is annual, and is controlled by the length of daylight.

The Accuracy International Arctic Warfare model has since spawned an entire family of sniper rifles using the Arctic Warfare name, and has been adopted by a number of other countries, including Australia, Belgium, Germany, Indonesia, Ireland, Latvia, Malaysia, Norway, the Netherlands, New Zealand, Russia, Singapore, Spain, Sweden and the United Kingdom. Other AI rifles descended from the L96A1 include the AI AE, and the AI AS50 (see variants below). Most Arctic Warfare rifles are chambered for the 7.62×51mm NATO cartridge, but Accuracy International also made variants of the sniper rifle, the AWM (Arctic Warfare Magnum) chambered either for the .300 Winchester Magnum and the .

The maps on the right show the average temperature over the Arctic in January and July, generally the coldest and warmest months. These maps were made with data from the NCEP/NCAR Reanalysis, which incorporates available data into a computer model to create a consistent global data set. Neither the models nor the data are perfect, so these maps may differ from other estimates of surface temperatures; in particular, most Arctic climatologies show temperatures over the central Arctic Ocean in July averaging just below freezing, a few degrees lower than these maps show (USSR, 1985). An earlier climatology of temperatures in the Arctic, based entirely on available data, is shown in this map from the CIA Polar Regions Atlas.

Among the Yup'ik near Kuskokwim Bay of Coastal Alaska, the word yua (absolutive case form of the word yuk "human; human-like spirit") has similar connotations as that of the Iñupiaq of Northern Alaska, who similar to the Inuit call it iñua or inua. For both the Yup'iak and Iñupiaq, the meaning is closest to an understanding of a world in which "Most Arctic peoples believe all the world is animate, and that animals have souls or spirits", (Berlo and Phillips 161) a foundational belief of the continuum and inter-connectivity of all life and spirit of all that which is, that which has been, and that which is yet to be.

The most notable was the 1596 expedition led by Dutch navigator Willem Barentsz, who discovered Spitsbergen and Bear Island, and rounded the north end of Novaya Zemlya. Fearing English and Dutch penetration into Siberia, Russia closed the Mangazeya seaway in 1619. Pomor activity in Northern Asia declined and most Arctic exploration in the 17th century was carried out by Siberian Cossacks, sailing from one river mouth to another in their Arctic-worthy kochs. In 1648, the most famous of these expeditions, led by Fedot Alekseev and Semyon Dezhnev, sailed east from the mouth of the Kolyma River to the Pacific Ocean, and rounded the Chukchi Peninsula, thus proving that no land connection existed between Asia and North America.

According to the study, "for the first time, sufficient loss occurred to reasonably be described as an Arctic ozone hole." The study analyzed data from the Aura and CALIPSO satellites, and determined that the larger-than-normal ozone loss was due to an unusually long period of cold weather in the Arctic, some 30 days more than typical, which allowed for more ozone-destroying chlorine compounds to be created. According to Lamont Poole, a co-author of the study, cloud and aerosol particles on which the chlorine compounds are found "were abundant in the Arctic until mid March 2011—much later than usual—with average amounts at some altitudes similar to those observed in the Antarctic, and dramatically larger than the near-zero values seen in March in most Arctic winters". In 2013, researchers analyzed the data and found the 2010–11 Arctic event did not reach the ozone depletion levels to classify as a true hole.

Most Arctic seas are covered by ice for part of the year (see the map in the sea-ice section below); 'ice-free' here refers to those which are not covered year-round. The only regions that remain ice-free throughout the year are the southern part of the Barents Sea and most of the Norwegian Sea. These have very small annual temperature variations; average winter temperatures are kept near or above the freezing point of sea water (about ) since the unfrozen ocean cannot have a temperature below that, and summer temperatures in the parts of these regions that are considered part of the Arctic average less than . During the 46-year period when weather records were kept on Shemya Island, in the southern Bering Sea, the average temperature of the coldest month (February) was and that of the warmest month (August) was ; temperatures never dropped below or rose above ; Western Regional Climate Center) The rest of the seas have ice cover for some part of the winter and spring, but lose that ice during the summer.
