Polar Bears Will Remain Protected Under Endangered Species Act
2013-03-03 06:38:25

redOrbit Staff & Wire Reports - Your Universe Online 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. According to Brent Kendall of the Wall Street Journal, the US Court of Appeals for the District of Columbia Circuit issued a...

Polar Bear Conservation: International Polar Bear Day
2013-02-27 05:01:55

April Flowers for redOrbit.com - Your Universe Online February 27 is International Polar Bear Day, sponsored and led by Polar Bear International (PBI). PBI is an advocacy group dedicated to research, education and action to protect the world's polar bear populations from extinction. PBI started International Polar Bear day to raise awareness of the bear's plight, and the damage that humans are inflicting with global warming. This year, PBI invites the public to join in by making Feb. 27...

New Research Suggests Climate Change Effect On Plant Communities Is Buffered By Large Herbivores
2013-02-20 15:00:34

Penn State 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. The study suggests that the answer to this question may have as much to do with the biological interactions that shape communities as with the effects of climate change itself. The study's insights are based on...

Arctic Carbon Dioxide Levels Affected By Ice Melt
2013-02-19 22:03:15

Michael Harper for redOrbit.com — Your Universe Online Last year, so much sea ice in the Arctic had melted away that it beat the prior record amount set in the summer of 2007. By the end of the 2012 summer, the Arctic Ocean had lost about 2.1 million square miles of ice, according to the U.S. National Snow and Ice Data Center (NSIDC) in Colorado. Experts began to predict the kinds of trouble such a speedy and significant melt could have on the earth´s ecosystems as a whole....

CryoSat-2 Shows Arctic On Thin Ice
2013-02-13 19:23:12

[ Watch the Video: Arctic Sea Ice Changes 2011-2012 ] Lee Rannals for redOrbit.com — Your Universe Online New observations using satellites have confirmed University of Washington researchers' analysis the Arctic Ocean sea ice really is thinning. A team combined new satellite observations, along with a model created by University of Washington researchers, to confirm the summer minimum in Arctic sea ice is one-fifth of what it was back in 1980, when the model started. The...

Polar Bears Threatened By Climate Change, Action Urged Now
2013-02-06 05:34:00

April Flowers for redOrbit.com - Your Universe Online 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. University of Alberta professor Andrew Derocher is one of the authors of a policy perspective recently published online in the journal Conservation Letters that urges governments with polar bear populations to...

Arctic Ocean Oil Spill Guidelines Not Good Enough, According To Greenpeace
2013-02-05 16:30:04

Lee Rannals for redOrbit.com — Your Universe Online 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. A Greenpeace representative told redOrbit there are a number of improvements to the document, due to be approved in May by the Arctic Council, that could be done. "We believe that the risks of being...

Ice Loss Not Due To 2012 Arctic Cyclone
2013-01-31 20:18:02

Lee Rannals for redOrbit.com — Your Universe Online Researchers are disputing the theory that the culprit behind the historic sea ice minimum was "The Great Arctic Cyclone of August 2012." Writing in the journal Geophysical Research Letters, University of Washington researchers found that the freak summer storm was actually not solely responsible for 2012's record low for Arctic sea ice, but that other factors were in play. Jinlun Zhang, lead author of the paper, and...

Extreme Weather Events May Synchronize Entire Communities Of Species
2013-01-18 04:26:31

April Flowers for redOrbit.com - Your Universe Online 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. A new study from the Norwegian University of Science and Technology (NTNU) has found that extreme climate events cause a synchronized population fluctuation among all vertebrate species in a relatively...

How Will Climate Change Impact Mammals In Arctic And Sub-Arctic Areas?
2013-01-15 10:36:14

UmeÃ¥ University The climate changes depicted by climatologists up to the year 2080 will benefit most mammals that live in northern Europe´s Arctic and sub-Arctic land areas today if they are able to reach their new climatic ranges. This is the conclusion drawn by ecologists at UmeÃ¥ University in a recently published article in the journal Plos ONE. The scientists Anouschka Hof, Roland Jansson, and Christer Nilsson of the Department of Ecology 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...

The Arctic fox (Alopex lagopus), also known as the polar fox, is a small fox native to cold Arctic regions of the Northern Hemisphere. It is common in all three tundra biomes. Although some authorities have suggested placing it in the genus Vulpes, it has long been considered the sole member of the genus Alopex. The Arctic fox has smaller, more rounded ears, a more rounded braincase. It has a slightly shorter and broader muzzle than the red fox. Its feet are furrier than those of other...
