Stronger winds explain puzzling growth of sea ice in Antarctica

Despite warming temperatures, Antarctic sea ice is on track to hit a record high. A new study suggests stronger polar winds can explain the recent increase in Southern Hemisphere sea ice.

Scientists review the ecological effects of sea ice loss

A UW atmospheric scientist is co-author of a review paper, published this week in the journal Science, looking at the ecological consequences of sea ice decline.

Santa’s workshop not flooded – but lots of melting in the Arctic

Widespread media reports of a lake at the North Pole don’t hold water — but scientists who deployed the monitoring buoys are watching closely as Arctic sea ice approaches its yearly minimum.

While stability far from assured, Greenland perhaps not headed down too slippery a slope

In a pair of companion papers in Science Express this week, scientists investigate the role of surface meltwater on accelerating the flow of the Greenland Ice Sheet and outlet glaciers and conclude that, while surface melt plays a substantial role in ice sheet dynamics, it may not produce large instabilities.

Glaciers not on simple, upward trend of melting

Two of Greenland’s largest glaciers shrank dramatically and dumped twice as much ice into the sea during a period of less than a year between 2004 and 2005.

Greenland’s glaciers pick up pace in surge toward the sea

With warming temperatures as the possible underlying cause, scientists wonder what is pushing Greenland’s glaciers out to sea as much as 50 percent quicker than before.

World’s fastest glacier doubles speed

The world’s fastest glacier, Greenland’s Jakobshavn Isbrae, doubled its speed between 1997 and 2003.
