Giant channels discovered under Antarctic ice

Beneath the floating Filchner-Ronne Ice Shelf in West Antarctica, scientists have discovered huge ice channels that are 800 feet high and stretch for hundreds of miles. The discovery, by researchers from the University of Exeter, Newcastle University, the University of Bristol, the University of Edinburgh, the British Antarctic Survey, and the University of York is […]

Arctic ice shrinks, Antarctic grows

While the dramatic decline in Arctic sea ice cover over the last three decades has been well documented, NASA climatologists say something more complex is happening at the other end of the planet. Their study shows that from 1978 to 2010 the total extent of sea ice surrounding Antarctica in the Southern Ocean grew by […]

Melting threat from ice sheet overestimated?

The total or partial collapse of the West Antarctic Ice Sheet would not raise global sea levels as high as predicted contends a new study, but the effects would be most strongly felt in coastal areas of the United States. Antarctica holds about nine times the volume of ice of Greenland and its western ice […]

Antarctic Snowfall Snafu Derails Climate Models

An improved method of measuring Antarctic snowfall has revealed that previous records showing an increase in precipitation are not accurate, even over a half-century. In the August 10 edition of Science magazine, researchers explain that their analysis of ice cores and snow pits revealed that precipitation levels in the Antarctic have in fact remained steady. […]
