Antarctica poised for record high as figures show Arctic sea ice was millions of square kilometres below long-term average
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 ...
Mahlon C. Kennicutt II, Steven L. Chown and colleagues outline the most pressing questions in southern polar research, and call for greater collaboration and environmental protection in the region.
John Abraham: A jump is discovered in estimated Antarctic sea ice extent due to a satellite algorithm
Antarctic sea ice may not be expanding as fast as previously thought, new research suggests. A team of scientists say much of the increase measured for Southern Hemisphere sea ice could be due to a processing error in the satellite data
A new report calls for protection measures in the Antarctic Weddell Sea, one of the world’s last, intact ecosystems. Cooperation between Germany and Russia could help achieve a better situation.
Polar bears are big animals. As the world's largest land predators, a single male can weigh over a staggering 700 kilograms (about 1,500 pounds). But as impressive as they are, it's difficult to imagine counting polar bears from space. Still, this is exactly what scientists have done according t ...
Field surveys and satellites complement each other when studying remote penguin populations.
A UK team believes it can now make skilful predictions of how much sea ice will melt during Arctic summers.
AUSTIN, Texas, June 9 (UPI) --The list of things that don't contribute to glacier melting keeps getting shorter. Now, the list-keeper can cross off "underground volcanoes."
Large ocean waves can travel through sea ice for hundreds of km before their oscillations are finally dampened, scientists have shown.
Two new studies show the West Antarctic ice sheet is melting faster than anticipated. Experts say IPCC global sea level forecasts will have to be recalculated with levels far higher than initially predicted.
The genetic analysis revealed that this specific bird flu strain is most closely related to H3N8, a strain from the 1960s.
Is Antarctica really safe from climate change? A new study suggests even the icy east of the frozen continent could be at risk, with consequences for global sea levels. Scientists say the changes could be irreversible.
Research using NASA data is giving new insight into one of the processes causing Greenland's ice sheet to lose mass.
Antarctica is the Earth’s last pristine, untouched and most epic wilderness.
CAMBRIDGE, England, Feb. 20 (UPI) -- A glacier on the West Antarctic Ice Sheet, already the largest single source of global sea level rise, may keep thinning for decades, scientists say.
As the Arctic continues to see dramatic declines in seasonal sea ice, warming temperatures and increased storminess, the responses of marine mammals can provide clues to how the ecosystem is responding to these physical drivers.
[SANTIAGO] With climate change causing Arctic sea ice to shrink to its smallest extent on record in 2012, opening up new sea routes and access to mineral deposits — including about 30 per cent of the world’s unexploited gas and 13 per cent of its oil according to some estimates — the Arctic re ...
As climate change warms the Arctic, oil rigs are opening, ships are making use of new shipping routes and tourists are flocking to see the icebergs.
MUNICH, Germany, Feb. 3 (UPI) -- Greenland's fastest-moving glacier is accelerating, moving ice from the Greenland ice sheet into the ocean at the fastest speed ever recorded, scientists say.
The ubiquitous shallow icy lakes that dominate Alaska's Arctic coastal plain have undergone a significant change in recent decades
The largest terrestrial predator on Earth is losing the ground under its feet.
Antarctica's mighty Pine Island Glacier (PIG) is now very probably in a headlong, self-sustaining retreat.
Antarctica's Pine Island Glacier, one of the biggest single contributors to world sea-level rise, is melting irreversibly and could add as much as a centimetre to ocean levels in 20 years, say scientists.
The bounce back in the extent of sea ice in the Arctic this summer was reflected also in the volume of ice.
Although the Arctic caught a break this year with a chilly summer, the region "continues to show evidence of a shift to new warmer, greener state" because of climate change, according to the annual Arctic Report Card issued Thursday by federal scientists.
The rapid melting in the Arctic eased up this year. But the government says global warming is still dramatically altering the top of the world, reducing the number of reindeer and shrinking snow and ice, while increasing certain fish and extending the growing season.
