A study of a Greenland ice core shows that during large climate swings, chemically reactive oxidants shift in a different direction than expected, which means we need to rethink what controls these molecules in our air.

A federal program that pays farmers to plant agricultural land with environmentally beneficial vegetation is probably the reason that sage grouse still live in portions of Washington’s Columbia Basin, according to a new study by UW, state and federal researchers.

John E. Vidale, a UW professor of seismology and director of the Pacific Northwest Seismic Network, has been elected to the National Academy of Sciences.

New analysis debunks reports that recent observations are showing that Earth’s temperature responds less to greenhouse gases than predicted by climate models.

A new study provides a postmortem on the Yukon’s Slims River, whose flow was diverted in early 2016. It is the only documented case of “river piracy” in modern times.

An algorithm for stock prices can be used with GPS data to automatically detect slow-slip earthquakes at a single station, offering a new way to monitor seismic activity.

A new analysis shows a properly-managed subsistence harvest of polar bears can continue under climate change.

Dramatic declines in Arctic sea ice during the past four decades are due to a mixture of global warming and a natural decades-long hot spot over Greenland.

University of Washington polar scientists are holding the 12th annual Polar Science Weekend, Friday through Sunday, March 3-5, at Pacific Science Center in Seattle. This year’s lineup includes a simulation from NASA of its new ICESat-2 instrument. Visitors can get scanned by an instrument above their head that measures a person’s height using an infrared distance sensor. The real ICESat-2 satellite, scheduled for launch in 2018, will map the Earth’s ice surfaces to very high precision, from space. During the…

Maritime communities take various forms around the planet and through the centuries. Margaret Willson, affiliate associate professor of anthropology and Canadian Studies Arctic Program at the University of Washington, is the author of “Seawomen of Iceland: Survival on the Edge,” published in 2016 by University of Washington Press. UW Today asked Willson a few questions about the book, in advance of her talk Feb. 17 at 7 p.m. at Seattle’s Center for Wooden Boats. How did you get interested in…

Ozone levels in June 2015 were significantly higher than normal over a large swath of the Western U.S. Analysis ties this air quality pattern to the abnormal conditions in the northeast Pacific Ocean, nicknamed “the blob.”

Drainage of four interconnected lakes below Thwaites Glacier in late 2013 caused only a 10 percent increase in the glacier’s speed. The glacier’s recent speedup is therefore not due to changes in meltwater flow along its underside.

Thousands of photos of glaciers, volcanoes, rivers and other natural phenomena are now easily viewed by the public through the University of Washington Libraries. UW Libraries’ Special Collections this fall released a new Glacier and Landforms Photograph Collection. The collection is designed to provide online access to photos of glaciers, geology and related subjects. At launch, the collection includes material from three photographers, and more will be added over time. Don Easterbrook, professor emeritus of geology at Bellingham’s Western Washington…

Researchers from across the UW are presenting their work at the American Meteorological Society’s annual meeting this week in Seattle.

The year 2016 was officially the hottest in recent history, beating previous records in 2014 and 2015. UW scientists let you hear the data speak for itself.

Vitamin B-12 exists in two different, incompatible forms in the oceans. An organism thought to supply the essential vitamin B-12 in the marine environment is actually churning out a knockoff version.

Autonomous floating sensors built at the UW are being deployed to track conditions in the waters surrounding Antarctica.

Ice core records from the two poles show that during the last ice age, sharp spikes in Arctic temperatures triggered shifts in the winds around Antarctica.

The cracking, bulging and shaking from the eruption of a mile-high volcano where two tectonic plates separate has been captured in more detail than ever before. A University of Washington study published this week shows how the volcano behaved during its spring 2015 eruption, revealing new clues about the behavior of volcanoes where two ocean plates are moving apart. “The new network allowed us to see in incredible detail where the faults are, and which were active during the eruption,”…

A University of Washington study addresses controversies over the cause of mountain glacier retreat, and finds that for most glaciers the observed retreat is more than 99 percent likely due to climate change.

Tracking the speed of internal tides offers a cheap, simple way to monitor temperature changes throughout the world’s oceans.

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 explorers’ experiences to better understand a maritime environment that still contains many unknowns. A paper published in November in Polar Geography uses Captain James Cook’s…
Major forest die-offs due to drought, heat and beetle infestations or deforestation could have consequences far beyond the local landscape. Wiping out an entire forest can have significant effects on global climate patterns and alter vegetation on the other side of the world.

Research shows that real-time lightning observations could significantly improve forecasts of large storm events.

Research that peers below Mount St. Helens finds that the material below the western and eastern half of the mountain is different material and temperatures, and suggests that the source of explosive magma is coming from the east.

Oceanographers used tools developed for semiconductor research to view the formation of a marine shell in the most detail yet, to understand how organisms turn seawater into solid mineral.

Unlike in the movies, and in some theories of climate change, the recent slowdown of Atlantic Ocean circulation is not connected with the melting of the Arctic sea ice. Instead, it seems to be connected to shifts around the southern tip of Africa.

University of Washington scientists have put world’s longest-running measure of atmospheric carbon dioxide to music. The result is a 90-second rendition of human-induced climate change: The video project was done by Judy Twedt, a UW doctoral student in atmospheric sciences, and Dargan Frierson, a UW associate professor of atmospheric sciences and amateur musician. Their techno soundtrack maps musical notes to the Keeling Curve, a 58-year record of carbon dioxide measured high in the atmosphere at the Mauna Loa Observatory in…

UW oceanographers are working on a system that will act like a ‘weather forecast’ for Pacific Northwest harmful algal blooms.

A study led by researchers at the University of Washington and the National Oceanic and Atmospheric Administration connects the unprecedented West Coast toxic algal bloom of 2015 to the unusually warm ocean conditions — nicknamed “the blob” — in winter and spring of that year.

UW scientists worked with artists for an exhibit at the Museum of Northwest Art focusing on climate change impacts on coastal communities.

The winds that gust across the Tibetan Plateau have done so for far longer than previously believed, showing they are resilient to the formation of mountains and changes in carbon dioxide and temperature.

UW atmospheric scientists are part of a month-long NASA effort to learn how smoke and clouds interact.

Many popular long-term drought estimates ignore the fact that plants will be less thirsty as carbon dioxide goes up. Plants’ lower water use could roughly halve some current estimates for the extent of future drought, especially in central Africa and temperate Asia.

Analysis of almost 3,000 pairs of Danish twins shows that they live longer than the general population, especially if they are identical.
