Snow has thinned on Arctic sea ice

Historic observations and NASA airborne data provide a decades-long record showing that the snowpack on Arctic sea ice is thinning.

Huge waves measured for first time in Arctic Ocean

The first measurements of waves in the middle of the Arctic Ocean recorded house-sized waves during a September 2012 storm. More sensors are going out this summer to study waves in newly ice-free Arctic waters.

Tracking the breakup of Arctic summer sea ice

An international team has placed sensors on and under Arctic sea ice to monitor this season’s retreat. Scientists hope to understand the physics of the ice edge in order to predict summer conditions in the Arctic Ocean.

West Antarctic Ice Sheet collapse is under way

The collapse of the West Antarctic Ice Sheet has begun, according to computer models using detailed topographic maps. The fast-moving Thwaites Glacier will likely disappear in a matter of centuries, researchers say, raising sea level by nearly 2 feet.

Greenland melting due equally to global warming, natural variations

Up to half of the recent warming in Greenland and surrounding areas may be due to climate variations that originate in the tropical Pacific and are not connected with the overall warming of the planet. Still, at least half the warming remains attributable to global warming caused by rising carbon dioxide emissions.

Polar science this weekend at Pacific Science Center

The 9th annual Polar Science Weekend will bring polar research, art and an actual ice core to the Pacific Science Center.

Whales, ships more common through Bering Strait

A three-year survey of whales in the Bering Strait reveals that many species of whales are using the narrow waterway, while shipping and commercial traffic also increase.

Greenland’s fastest glacier sets new speed record

Observations of Jakobshavn Glacier from 2012 and 2013 show the fast-moving glacier has set new records for the speed of ice flowing toward the ocean.

‘Future of Ice’ initiative marks new era for UW polar research

The UW’s new “Future of Ice” initiative includes several new research hires, a new minor in Arctic studies and a free winter lecture series.

El Niño tied to melting of Antarctica’s Pine Island Glacier

A new study in Science, co-authored by the British Antarctic Survey and UW authors, shows that melting of the floating Pine Island ice shelf is tied to global atmospheric patterns associated with El Niño.
