See also: “How Capt. James Cook’s intricate 1778 records reveal global warming today in Arctic” Seattle Times, Nov. 16 Harry Stern, a polar scientist at the University of Washington’s Applied Physics Laboratory, has been studying the Arctic Ocean for decades, and sailed part of the Northwest Passage in 2009. Stern’s latest work uses the earliest…

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 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.
