Image 1 - Link Found Between Summer Arctic Sea Ice Cover And Winter Weather In Central Europe
2012-02-02 08:04:05

Even if the current weather situation may seem to speak against it, the probability of cold winters with much snow in Central Europe rises when the Arctic is covered by less sea ice in summer. Scientists of the Research Unit Potsdam of the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association have decrypted a mechanism in which a shrinking summertime sea ice cover changes the air pressure zones in the Arctic atmosphere and impacts our European winter weather....

These researchers assert that the Arctic is already suffering some of the effects that, according to The Intergovernmental Panel on Climate Change (IPCC), correspond with a "dangerous climate change". Currently, the rate of climatic warming exceeds the rate of natural adaptation in arctic ecosystems. Furthermore, the Eskimo population is witnessing how their security, health and traditional cultural activities jeopardize. The experts demand an effort in order to develop indicators that...

New Study Sheds Light On Little Ice Age
2012-01-30 15:44:41

University of Colorado researchers report that they have answered some questions surrounding Earth's Little Ice Age, which started between A.D. 1275 and 1300, and lasted into the late 19th century. According to the new study, the Little Ice Age was triggered by repeated, explosive volcanism and sustained by a self-perpetuating sea ice-ocean feedback system in the North Atlantic Ocean. Professor Gifford Miller, who led the study, said the team's evidence from radiocarbon dates from dead...

Killer whales (Orcinus orca) are the top marine predator, wherever they are found, and seem to eat everything from schools of small fish to large baleen whales, over twice their own size. The increase in hunting territories available to killer whales in the Arctic due to climate change and melting sea ice could seriously affect the marine ecosystem balance. New research published in BioMed Central's re-launched open access journal Aquatic Biosystems has combined scientific observations with...

Rising temperatures and melting ice could prove to be an economic boon to Russia, thanks to the revitalization of a Soviet-era maritime shipping route along the coast of Siberia, according to Reuters reports on Friday. That path is known as the Northern Sea Route and to links the Atlantic and Pacific Oceans through a route along the nation's Arctic coast from Murmansk on the Barents Sea to the Bering Strait and the Far East. Previously known as the Northeast Passage, the route, which...

Image 1 - Scientists Find An Abundance Of Fresh Water In The Arctic
2012-01-23 08:09:14

[ Watch the Video ] A massive pool of fresh water in the Arctic Ocean -- a result of melting ice and river runoff -- has been discovered by British scientists who believe it is expanding and could lower temperatures in Europe by causing the ocean current to slow down. Scientists from University College London and Britain´s National Oceanography Center found that the western Arctic´s sea surface has risen by 6 inches since 2002. The rise could be due strong Arctic winds...

International experts to recommend key issues as Canada prepares to assume Arctic Council chair With an eye on rapid changes in the resource-rich Arctic, countries like China, India and Brazil, which have no Arctic territories, are nonetheless knocking on the door of the increasingly influential Arctic Council looking for admission as permanent observers. The issue has divided existing members, with Russia and Canada most strongly opposed. It is among the major questions with which...

Cold Winters May Be Caused By Warmer Summers
2012-01-14 04:15:14

Scientists have offered up a convincing explanation for the harsh winters recently experienced in the Northern Hemisphere; increasing temperatures and melting ice in the Arctic regions creating more snowfall in the autumn months at lower latitudes. Their findings may throw light on specific weather incidents such as the extremely harsh Florida winter of 2010 which ended up killing a host of tropical creatures, as well as the chaos-causing snow that fell on the UK in December 2010....

Image 1 - Russian River Runoff Freshening Beaufort Sea
2012-01-05 13:33:42

According to findings published in the journal Nature, Russian river water was diverted hundreds of miles to a different part of the ocean in response to a decades-long shift in atmospheric pressure. Researchers found that a low pressure pattern created by the Arctic Oscillation from 2005 to 2008 drew Russian river water away from the Eurasian Basin and into the Beaufort Sea. This diversion resulted in adding 10 feet of freshwater over the central part of the Beaufort Sea. "Knowing...

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...

  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
