Ice core shows North American ice sheet’s retreat affected Antarctic weather

Sea ice and icebergs in the Southern Ocean in 2017 off the coast of West Antarctica. The new study looks at the year-to-year variability of storms in this region.

Researchers at the University of Washington were among the co-authors of a new study that uses ice core data to see how Earth’s climate behaved at the end of the last ice age, when the Laurentide Ice Sheet covering much of North America retreated about 16,000 years ago. The study led by the University of Colorado Boulder is published online this week and will be in the Feb.

University of Washington scientists are part of an international team that is spending six weeks in the remote Southern Ocean to tackle one of the region’s many mysteries: its clouds. What they discover will be used to improve climate models, which routinely underestimate how much solar energy bounces off clouds in that region. Simulating how much solar energy is absorbed or reflected on Earth is key to calculating the future of the planet under climate change.

UW, other leading research universities form international coalition to speed local climate action

Researcher David Shean uses UW’s terrestrial laser scanner to measure surface elevation at the South Cascade Glacier.

The University of Washington joins 12 other leading North American research universities in the new University Climate Change Coalition, or UC3, a group committed to leveraging its research and resources to help communities accelerate climate action. The coalition, which launched Feb. 6, includes universities that have committed to mobilize their resources and expertise to accelerate local and regional climate action in partnership with businesses, cities and states.

A new grant will let a University of Washington-based project add a new fleet to its quest to learn more about past climate from the records of long-gone mariners. The UW is among the winners of the 2017 “Digitizing Hidden Special Collections and Archives” awards, announced Jan. 4 by the Washington, D.C.-based Council on Library and Information Resources. The new $482,018 grant to the UW, the U.S.

Partnership will use robotic network to explore Antarctic ice shelves

One of the biggest unknowns for the future of Earth’s climate is Antarctica, where the West Antarctic Ice Sheet holds so much ice that, if it collapsed, it could bring several feet of rising seas. A new partnership between the University of Washington’s College of the Environment, the UW Applied Physics Laboratory and Paul G. Allen Philanthropies will use a robotic network to observe the conditions beneath a floating Antarctic ice shelf.
