Greenland To Get Greener Climate Change
2013-08-28 12:55:57

Brett Smith for redOrbit.com - Your Universe Online While climate change may affect temperate zones around the Earth by a degree or two, temperatures in the Arctic are expected to increase by much more than the global average, according to a likely scenario predicted by the Intergovernmental Panel on Climate Change. This reality means that Greenland could eventually become a much more hospitable place for some species of Arctic trees, and a new analysis by a team of European researchers...

Sea Ice Decline Changing The Vegetation Of The Arctic
2013-08-23 10:26:03

Geophysical Institute, University of Alaska Fairbanks Sea ice decline and warming trends are changing the vegetation in nearby arctic coastal areas, according to two University of Alaska Fairbanks scientists. Uma Bhatt, an associate professor with UAF’s Geophysical Institute, and Skip Walker, a professor at UAF’s Institute of Arctic Biology, contributed to a recent review of research on the response of plants, marine life and animals to declining sea ice in the Arctic. “Our...

2013 Ice Melt Will Not Be Record Year Despite Continuing Downhill Trends
2013-08-23 10:06:14

[WATCH VIDEO: Summer Arctic Ice Retreat 2013] Lee Rannals for redOrbit.com - Your Universe Online Arctic sea ice is reaching its annual "minimum" melt for the summer, but NASA says this year's low will unlikely be breaking any records. Last year, Arctic sea ice melted to a record low, making it the largest summer melt since satellites began measuring the process in 1979. This year's melt is beginning to reach its minimum now, and even though it’s not going to catch any records,...

A new paper co-written by UM associate professor Mark Hebblewhite details ecological changes caused by a loss of Arctic sea ice. The paper concludes that the loss of sea ice obviously will impact the marine food web and the marine mammals that depend on sea ice habitat. Other major ecological changes in adjacent land-based habitats and species also will occur because of warming oceans. The findings were published in the Aug. 2 issue of Science magazine. Wildlife species like the polar...

Climate Change Not Improving NOAA Report
2013-08-07 09:43:37

Brett Smith for redOrbit.com - Your Universe Online Last year was one of the hottest twelve months on record, according to a new report from the National Oceanic and Atmospheric Administration (NOAA) that analyzed global temperatures and climate trends. The US government agency's report was assembled by over 380 scientists from 52 countries. In addition to analyzing temperature data, the annual report also gave the status of other global climate indicators and significant weather...

Wildlife Greatly Impacted By Arctic Sea-Ice Loss
2013-08-02 07:11:40

April Flowers for redOrbit.com - Your Universe Online Because sea ice is at its lowest point in 1,500 years, scientists are questioning how ecological communities in the Arctic will be affected by this continued and perhaps accelerating melting process over the next two decades. An international team of scientists, led by Penn State University biologist Eric Post, examined relationships among algae, plankton, whales, and terrestrial animals such as caribou, arctic foxes, and walrus, as...

Slight changes in the timing of the annual loss of sea-ice in polar regions could have dire consequences for polar ecosystems, by allowing a lot more sunlight to reach the sea floor. The research by scientists at UNSW and the Australian Antarctic Division predicts that biodiversity on some areas of the polar seabed could be reduced by as much as one third within decades, as the poles warm. The study, Light-driven tipping points in polar ecosystems, will be published in the journal...

Polar Pool Not Extreme
2013-07-31 11:23:48

Brett Smith for redOrbit.com - Your Universe Online Last week, pictures from the North Pole Experimental Observatory (NPEO) showed the North Pole seemingly covered by a sea of water, but according to a statement from the project's principal investigator, conditions in the Arctic are typical for this time of year and viewing the images is all a matter of perspective. "Every summer when the sun melts the surface the water has to go someplace, so it accumulates in these ponds," said Jamie...

Arctic Winters Were Ice-Free Three To Five Million Years Ago
2013-07-30 06:29:43

April Flowers for redOrbit.com - Your Universe Online During the Pliocene Epoch, the Earth was substantially warmer than it is today, despite similar concentrations of carbon dioxide in the atmosphere. A new study, led by the University of Colorado Boulder, suggests year-round ice-free conditions across the surface of the Arctic Ocean could explain the difference. The study was published in a recent issue of Palaeogeography, Paleoclimatology, Palaeoecology. A new record was marked by...

UK Government Accused Of Being Complacent Over Arctic Drilling
2013-07-29 05:00:33

redOrbit Staff & Wire Reports - Your Universe Online The UK government has been accused by a coalition of environmental advocates of failing to protect the Arctic from oil and gas drilling, allowing projects to commence without performing adequate risk assessment. According to the Belfast Telegraph, Members of Parliament (MPs) on the Environmental Audit Committee (EAC) have accused the coalition government of "complacently standing by" while drilling projects commence despite the...

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...
