University of Washington polar scientists are on Alaska’s North Slope this week for the 2016 Barrow Sea Ice Camp. Supported by the National Science Foundation, the event brings together U.S.-based sea ice observers, satellite experts and modelers at various career stages to collect data and discuss issues related to measuring and modeling sea ice. The…

A study by the UW and others finds that the darkening of the Greenland ice sheet is not due to an increase in wildfires, but is a side effect of a warming climate.

UW glaciologists helped drill the first deep ice core at the South Pole, which will provide new clues to Antarctica’s climate history.
December 3, 2015
A citizen science project that asks volunteers to transcribe historic ships’ logbooks to uncover data about past Arctic climate has added logbooks from hundreds of whaling ships. The hunters’ handwritten logs will provide new clues about the history of Arctic climate and sea ice.

A University of Washington scientist is lead author on the first census of all Arctic marine mammals, including whales, walruses, seals and polar bears. The multinational report assesses the current status of these populations and makes recommendations for conservation of these species under climate change.

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.
