Arctic air temperatures were approximately 2.5 degrees Fahrenheit higher in 2011 than the baseline number for the previous three decades, and the region continues to lose ice sheet and glacier mass at a "dramatic" rate, according to a new report released by an international team of scientists Thursday. The 2011 Arctic Report Card, which was compiled by a team of 121 scientists from 14 different countries, measures the status of the area in five different categories: atmosphere, sea ice and...

Record-Breaking Arctic Warming Leaves Winners And Losers
2011-12-02 14:44:46

A new report from a group of multination scientists says that the planet´s Arctic is moving into a warmer phase compared with previous years. And as with most all major environmental changes, there are both winners and losers as temperatures rise. Researchers from 14 nations published the now famous Arctic Report Card on Thursday in which they stated that average air temperatures in the region were significantly elevated in 2011 compared with previous thirty years--on average some 2.5...

Global Temperatures On The Rise
2011-11-30 07:00:38

The UN´s World Meteorological Organization (WMO) has issued a new report, the annual World Meteorological Organization Statement on the Status of the Global Climate. The report was released Nov. 29 in Durban, South Africa at an international climate conference. The report states that 2011 was the tenth warmest year on record and the surface temperatures were higher than any previous year with a La Nina event, which has a cooling effect. The report also notes that the incidence of...

The National Snow and Ice Data Center reports that Arctic sea ice continues to shrink each summer to nearly record low levels, with this year´s ice loss the second-lowest ever since records first began being taken in 1979. Despite only a few decades worth of records, a new study, published in the British journal Nature, found that “both the duration and magnitude of the current decline in sea ice seem to be unprecedented for the past 1,450 years,” reported the authors. The...

The mention of lemmings usually evokes images of small rodents throwing themselves off the top of cliffs in acts of mass suicide; however, their reputations might no longer be determined by hearsay as a new report suggests they could be having an intricate effect on the Earth's climate. The study, published today, 18 November, in IOP Publishing's journal Environmental Research Letters, suggests that lemmings may be maintaining the biomass of certain plants in the Arctic at a time when the...

Image 1 - Trees On Tundra's Border Growing Faster In A Hotter Climate

Measuring Techniques Improve–But the Implications Are Not Certain Evergreen trees at the edge of Alaska´s tundra are growing faster, suggesting that at least some forests may be adapting to a rapidly warming climate, says a new study. While forests elsewhere are thinning from wildfires, insect damage and droughts partially attributed to global warming, some white spruce trees in the far north of Alaska have grown more vigorously in the last hundred years, especially since...

Arctic Sea Ice Could Melt Away By 2015
2011-11-09 06:19:43

A Cambridge University professor and one of Britain´s top ocean experts says that Arctic sea ice could melt away entirely by 2015, the Telegraph reported on Tuesday. Although the ice would reappear again every winter, its absence during the peak of summer would deprive polar bears of their summer hunting ground, which could put them at risk of extinction, said Professor Peter Wadhams of Cambridge University. The vast mass of sea ice between northern Russia, Canada and Greenland...

Greenland And The Netherlands Look To CryoSat For Answers On Ice
2011-10-17 07:54:30

As the impact of climate change is felt in the Arctic, ESA´s CryoSat ice mission is highlighted as a source of vital information at an exhibition in the Netherlands opened by HRH the Prince of Orange. The exhibition, called Roots2Share, opened on 13 October at the museum of culture and science, Museon, in The Hague. The aim of the exhibition is to highlight the cultural relationship between Greenland and the Netherlands and their interests in understanding more about the Arctic and...

2011-10-06 11:09:06

In the central Arctic the proportion of old, thick sea ice has declined significantly. Instead, the ice cover now largely consists of thin, one-year-old floes. This is one of the results that scientists of the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association brought back from the 26th Arctic expedition of the research vessel Polarstern. The ship arrived at its home port of Bremerhaven at about 7 o´clock this morning. Prior to that it had covered more...

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...
