Strong winds blowing off the Greenland Ice Sheet are eroding soil and vegetation in the surrounding tundra, making it less productive for caribou and other grazing animals, carbon storage and nutrient cycling, a Dartmouth College study finds.
Hot vents in Antarctica's Southern Ocean are crowded with cold, hairy crabs. Blind and surrounded by freezing water, they must huddle close to the vent chimneys that power their ecosystem.
In a comprehensive assessment of Antarctic biodiversity scientists have revealed the region is more diverse and biologically interesting than previously thought.
Scientists were baffled last year after meltwater lakes atop Greenland's ice sheet suddenly drained out at rates rivaling Niagara Falls.
A major new initiative to bridge the gap between scientists and decision makers has been launched during the annual Antarctic Treaty Consultative meeting, ATCM XXXVIII - CEP XVIII, in Bulgaria.
Satellites have seen a sudden dramatic change in the behaviour of glaciers on the Antarctica Peninsula, according to a Bristol University-led study.
The Polar Code, passed at a meeting in London of the International Maritime Organization (IMO), ban ships from releasing oil, sewage, chemicals and waste into the sea.
The last intact section of one of Antarctica’s mammoth ice shelves is weakening fast and will likely disintegrate completely in the next few years, contributing further to rising sea levels, according to a Nasa study released on Thursday.
Future research into the underground lakes could reveal secrets as to the ways microorganisms survive deep beneath the surface.
White on top, but what lies beneath? Antarctica's blanket of snow and ice sits atop a vast and rich landscape of volcanoes, rivers and lakes
RESTON, Va., April 1 (UPI) -- A number of studies have suggested polar bears are exasperated by the scarcity of sea ice -- their hunting and breeding patterns disrupted.
ESPERANZA BASE, Argentina, March 30 (UPI) -- Global warming continues to have its most pronounced effects on Earth's polar regions. Last week in Antarctica, those effects set a new record.
Sea ice in the Arctic Ocean has fallen to the lowest recorded level for the winter season, according to US scientists.
The good news is tempered by the fact that satellite data show ice levels in the rest of the Arctic -- and overall -- are at their lowest levels this winter.
The first study of ancient populations of the world's largest penguin, the emperor penguin, has raised serious concerns about the future prospects of the species.
DEKALB, Ill., Jan. 22 (UPI) -- It shouldn't be all that surprising at this point -- living organisms defying the odds, that is.
Winter is the dark season and colder than cold in the Arctic north. But climate warming is giving scientists the chance to find out what goes on in the Arctic ocean during the Polar night.
ANCHORAGE, Alaska, Jan. 8 (UPI) -- As habitats to the east and south of the Arctic region become more unstable -- and as suitable habitat continues to erode -- polar bears are relocating to far-northern Canada, where sea ice is plentiful and reliable.
Sea ice in the Antarctic is much thicker than previously thought, according to new data obtained by robotic submarines.
A mechanism that could turn out to be a big contributor to warming in the Arctic region and melting sea ice has been identified by scientists.
Meeting of 25 nations, including Russia and Ukraine, in Hobart will consider proposals on the future of Antarctic research and marine protection
The growth of sea ice is not evidence against the effects of climate change, but rather the consequence of it.
It’s increasingly difficult to find food using traditional hunting methods in the Arctic, and at the same time, provisions sold at stores are “unaffordable” for many, jeopardizing food security and cultural life in the region, Arctic experts and residents said, responding to a United Nations rep ...
NEW YORK, Sept. 28 (UPI) -- A team of researchers recently studied 120 ice sheets collapses and other factors to put together the history of sea level rise for the past 500,000 years.

Increased snowfall will not prevent the continued melting of glaciers in the northern Antarctic Peninsula, according to new research.
The founding meeting of the Arctic Economic Council is taking place in Canada (Sept. 2-3). Critics fear the new business body will speed up the exploitation of a fragile environment struggling with climate change.
Climate and ocean changes blamed for huge losses of puffins, kittiwakes, and terns
Satellite data shows ice sheets of Greenland and Antarctica are declining at record speed. The annual loss of ice has doubled in the case of Greenland and tripled in the West Antarctic compared to figures from 2009.
A cold breeze blew off the Antarctic plain, numbing the noses and ears of scientists standing around a dark hole in the ice. Flecks of ice crackled off a winch as it reeled the last few metres of cable out of the hole. Two workers in sterile suits leaned over to grab the payload — a cylinder the ...
This iconic species should be listed under the Convention on Migratory Species and specific protection measures agreed
Seismic events aren't rare occurrences on Antarctica, where sections of the frozen desert can experience hundreds of micro-earthquakes an hour due to ice deformation. Some scientists call them icequakes. But in March of 2010, the ice sheets in Antarctica vibrated a bit more than usual because of ...
