Antarctic sea ice is constantly on the move as powerful winds blow it away from the coast and out toward the open ocean. A new study shows how that ice migration may be more important for the global ocean circulation than anyone realized. A team of scientists used a computer model to synthesize mil...

The concentration of heat-trapping CO2 pollution in the atmosphere has passed the 400 parts per million (ppm) threshold in Antarctica for the first time in at least 800,000 years, and possibly as long as four million years, scientists reported this week. The new measurements, reported by British an...

It may sound unlikely, but the evidence is mounting that the more the Antarctic warms under the impact of climate change, the more snow will fall on it. Not only that, says a team of European and US scientists, but as the snow turns to ice it is going to flow downhill, borne by its own weight, and ...

Six massive glaciers in West Antarctica are moving faster than they did 40 years ago, causing more ice to discharge into the ocean and global sea level to rise, according to new research. The amount of ice draining collectively from those half-dozen glaciers increased by 77 percent from 1973 to...

Resting near the bottom of the food chain, Antarctic krill (Euphausia superba) underpin much of the Southern Ocean's ecosystem. But in a rapidly warming world, these hugely-abundant crustaceans could see their habitat shrink considerably. In a recent paper in PLOS ONE, scientists predict that Antarc...

High on the icy, windswept plateau of East Antarctica an international team of scientists is about to assemble a time machine. First stop: back to the era when Christ was born. If all goes well, the Australian-led team hopes to eventually retrace one-million years of atmospheric history by drilling...

Rapid thawing of the Arctic could trigger a catastrophic "economic timebomb" which would cost trillions of dollars and undermine the global financial system, say a group of economists and polar scientists. Governments and industry have expected the widespread warming of the Arctic region ...

While 99 percent of Earth’s land ice is locked up in the Greenland and Antarctic ice sheets, the remaining ice in the world’s glaciers contributed just as much to sea rise as the two ice sheets combined from 2003 to 2009, says a new study led by Clark University and involving the University Colorado...

  The Byrd Station sits on the West Antarctic Ice Sheet (WAIS), supporting scientific missions to explore the Antarctic environment. Temperatures monitored at the Byrd Station dating back to 1958 have now been studied by researchers from Ohio State University, who report: a marked i...

Plant life thrived about 15 million to 20 million years ago, new research finds The few plants that live in Antarctica today are hardy hangers-on, growing just a few weeks out of the year and surviving poor soil, lack of rain and very little sunlight. But long ago, some parts of Antarctica were alm...
