Northward winds are driving the record growth of winter sea ice around Antarctica, which stands in contrast to the extensive melting of the Arctic sea ice in recent years, scientists reported Sunday.
Isolated from the rest of the planet for 14 million years, Lake Vostok may be the only body of water on Earth to contain no life whatsoever. However, if life is discovered, it will be a big boost for researchers hoping to find microorganisms on icy moons like Europa.
The rumble of a 40-year-old plane packed with scientists has returned to the Antarctic skies. NASA's Operation IceBridge recently kicked off its fourth year with a survey of land and sea ice in West Antarctica, near the bay where a massive iceberg may soon break off Pine Island Glacier.
In a study led by the University of Tasmania, satellite technology has been used to "weigh" the land mass of Antarctica and measure how that changes over time. The university's Professor Matt King says the study improved the technique for measuring land mass, resulting in a more accurate picture of...
The rapid ice loss in the Arctic is strongly related to warming in the region, although storms and winds contribute as well. In the Antarctic, processes which govern ice changes are more complex and not as well-understood, but it is thought changes in atmospheric circulation (in part, perhaps,...
Inside the National Ice Core Laboratory in Denver rests more than 11 miles of ice, drilled from Earth's glaciers, which are shedding new light on the dimly understood history of the planet's climate. These ice cores, taken from both Antarctica and the Arctic, provide a unique glimpse into the past...
As the Arctic Ocean becomes more and more exposed with the loss of its ice-white blanket in the summer, more and more water will be evaporated into the atmosphere, creating increased humidity and stormy weather as it’s precipitated out. The ice cover in the north also reflects sunlight and heat,...
Arctic sea ice melted to 1.32 million square miles this September -- an unprecedented low and a sharp drop from the 2.59 million square mile average for this time of year. It also marks the greatest Arctic ice melt since satellite observations began in 1979.
Collecting data on the Arctic's response to past temperature swings will also help scientists more accurately predict the effects of global warming, through testing of climate models.
The Northern Hemisphere's largest expanses of ice have thawed faster and more extensively this year than scientists have previously recorded. And the summer isn't over.
Arctic sea ice is set to reach its lowest ever recorded extent as early as this weekend, in "dramatic changes" signalling that man-made global warming is having a major impact on the polar region.
The Antarctic Peninsula, which juts out about 1,000 miles (1,610 kilometers) from the western flank of the frozen continent, is one of the fastest warming places on Earth.
In just a few decades, many of the park's glaciers have shrunk dramatically. Since 1966, 11 of them have completely melted away. There were once 150 glaciers in the park. Now there are just 25, and scientists believe in the next 10 to 20 years, they could all be gone.
Arctic sea ice is vanishing much faster than generally expected, according to preliminary data from European Space Agency satellite Cryosat.
The Greenland ice sheet, the second-largest ice body in the world, has lost its ice in fits and starts — with short bursts of dramatic ice loss separated by periods of stability, a study has found.
