New University of Washington-led research attributes accelerated warming to reduced cloud reflectivity. As efforts to improve air quality have reduced pollution, clouds became less mirror-like, letting more solar radiation reach Earth and revealing the true impact of greenhouse gases.

In the wake of One Ocean Week Seattle, participating University of Washington researchers share highlights, connecting the week’s events to ongoing efforts to understand and protect marine ecosystems and coastal communities.

A new collaborative study led by scientists at the University of Washington and the University of Maryland Center for Environmental Science proposes that a tsunami struck the Caribbean island of Anegada between 1381 and 1391, carrying huge coral boulders inland and leaving behind a valuable record of geologic and climatic history.

A new analysis of data from the Cassini space probe has identified organic compounds within jets of water ice erupting from Saturn’s moon Enceladus. Some of the compounds, which likely originated in Enceladus’ subsurface ocean, have never before been identified on another world beyond Earth. The study, conducted in part by a UW researcher, contributes to mounting evidence that Enceladus could support life.

Bee experts wouldn’t have previously expected to find the likes of Osmia cyaneonitens, Dufourea dilatipes and Stelis heronae in Washington. But this year, while collecting pollinators in Chelan County to study how climate and wildfires affect native bee populations, Autumn Maust, a University of Washington research scientist of biology, discovered eight bee species never recorded in Washington.

University of Washington researchers found, in historical whaling data, that longer baleen whale mothers were more likely to birth female calves than males. These results run contrary to a leading evolutionary theory that suggests that fit mothers will benefit more from male offspring.

Antarctic ice is melting at a startling pace, and the West Antarctic Ice Sheet is one of the greatest sources of uncertainty in climate projections. Researchers thought westerly winds were accelerating ice loss, but a new study from UW flips the narrative by 90 degrees, pointing instead to winds from the north.

Prochlorococcus, the most abundant photosynthesizing organism in the ocean, might be more vulnerable to climate change than researchers thought. Population decline could weaken the foundation of subtropical and tropical ecosystems as ocean temperatures continue to rise.

New findings call into question one of the core assumptions about teeth. Adult male spotted ratfish, a shark-like species native to the eastern Pacific Ocean, have rows of teeth on top of their heads, lining a cartilaginous appendage called the tenaculum, in addition to those in their jaws. They used their tenaculum teeth to grip females while mating in water.

The positive impact of Big Ten universities across the Pacific Northwest and around the nation will be highlighted in a new 30-second ad that will air during sporting events featuring conference members, starting with this week’s season-opening football games. The ad – entitled “We Are Here” – will air alongside the fan-favorite “Maps” spot. The new spot focuses on how the University of Washington and other Big Ten universities make America healthier, safer and more prosperous in a variety of…

The University of Washington’s College of the Environment will expand its work related to climate solutions thanks to a grant announced today from Fund for Science and Technology, FFST, a new foundation within the Paul G. Allen philanthropic ecosystem.

New research shows that deep-ocean oxygenation occurred 100 million years later than previously thought, aligning with the growth and spread of land plants. Once oxygenated, the ocean hosted rapid animal evolution, leading to the rise of modern vertebrates.

University of Washington researchers use AI to simulate the Earth’s current climate and interannual variability for up to 1,000 years. The model runs on a single processor and takes just 12 hours to generate a forecast.

A UW-led team of researchers used a fiber-optic cable to capture calving dynamics across the fjord of the Eqalorutsit Kangilliit Sermiat glacier in South Greenland. This allowed them to document — without getting too close — one of the key processes that is accelerating the rate of glacial mass loss and in turn, threatening the stability of ice sheets, with consequences for global ocean currents and local ecosystems.

An international research effort, including scientists from the University of Washington, has finally revealed the cause of sea star wasting disease: a strain of the bacterium Vibrio pectenicida.

University of Washington researchers showed that they can monitor seismic activity at the ocean floor using fiber optic cables without disrupting telecommunications. They developed this technique in Alaska and then tested it off the coast of Oregon.

Kendall Valentine, an assistant professor of oceanography at University of Washington, along with collaborators from the University of Rhode Island and the Desert Research Institute are traveling to Anchorage and the Copper River Delta to study marshes that formed in the years following the 1964 earthquake.

University of Washington Provost Tricia R. Serio announced that Joel Thornton has agreed to serve as interim dean of the College of the Environment, effective July 1, until a new permanent dean is selected.

The University of Washington is No. 8 on the 2025-26 U.S. News & World Report’s Best Global Universities rankings, released on Tuesday. The UW maintained its No. 2 ranking among U.S. public institutions.

A new University of Washington–led study projects that in the next 35 years increasing boreal fires will actually slow global warming by 12% globally and 38% in the Arctic. Because the aerosols in smoke reflect more sunlight and make clouds brighter, summer temperatures during fire season drop, leading to reduced sea ice loss and cooler winter temperatures.

The study revealed that iron released from industrial processes, such as coal combustion and steelmaking, is altering the ecosystem in the North Pacific Transition Zone, an area just north of Hawai’i that’s important for Pacific fisheries.

The Atlantic Meridional Overturning Circulation, or AMOC, is a system of ocean currents that plays a crucial role in regulating Earth’s climate by transporting heat from the Southern to Northern Hemisphere. Climate models have long predicted that global warming will cause the AMOC to weaken, with some projecting what amounts to a near-collapse relative to the AMOC strength in observations today. But a new study from a team of researchers that included the University of Washington shows that the AMOC is likely to weaken to a much lesser extent than current projections suggest.

New research from the University of Washington, recently published in the Journal of Environmental Education, examined whether children’s interactions with nature that are embodied, rather than just visual, are associated with feeling connected to something beyond the self. Exploratory analyses found that participants who had embodied interactions reported a greater sense of presence in nature than those who reported only visual interactions.

The University of Washington’s graduate and professional degree programs were widely recognized as among the best in the nation, according to U.S. News & World Report’s 2026 Best Graduate Schools released late Monday.

Five University of Washington researchers have been named AAAS Fellows, according to a March 27 announcement by the American Association for the Advancement of Science. They are among 471 newly elected fellows from around the world, who are recognized for their “scientifically and socially distinguished achievements” in science and engineering.

The University of Washington is the best in the U.S. and No. 2 in the world for library and information management, according to the QS World University Rankings by Subject released Wednesday. Four other UW subject areas placed in the top 10.

For Valentine’s Day, UW News asked 12 University of Washington researchers to share their love stories: What made them decide to pursue their career paths?

A recent theory proposes that whales weren’t just predators in the ocean environment: Nutrients that whales excreted may have provided a key fertilizer to these marine ecosystems. Research led by University of Washington oceanographers finds that whale excrement contains significant amounts of iron, a vital element that is often scarce in ocean ecosystems, and nontoxic forms of copper, another essential nutrient that in some forms can harm life.

How fast the level of atmospheric carbon dioxide — and with it, the temperature — goes up matters for the ability of humans and ecosystems to adjust. A slower increase gives humans time to move away from low-lying coasts and animals time to move to new habitats. It turns out the rate of that increase matters for non-living systems, too. Camille Hankel, a postdoctoral researcher at the Cooperative Institute for Climate, Ocean and Ecosystem Studies, talks about her research on the Atlantic Ocean circulation.

UW oceanographer Robert Morris and a collaborator at UCLA are going out with students to collect the most abundant bacteria in the oceans to understand how its relationship with marine viruses changes depending on the place or the season. They leave Dec. 16 aboard UW School of Oceanography’s small research vessel, the RV Rachel Carson.

Colony surveys of common murres, an Alaskan seabird, show the full effects of the 2014-16 marine heat wave known as “the blob.” Analysis of 13 colonies surveyed between 2008 and 2022 finds that colony size in the Gulf of Alaska dropped by half after the marine heat wave. In colonies along the eastern Bering Sea, west of the peninsula, the decline was even steeper, at 75% loss. No recovery has yet been seen.

University of Washington researchers show that the all-time record low in winter sea ice extent in 2023 can be explained by warm Southern Ocean conditions and patterns in the winds that circled Antarctica months earlier, allowing forecasts for sea ice coverage around the South Pole to be generated six or more months in advance. This could support regional and global weather and climate models.

From a base at the southwest corner of the UW’s Seattle campus, the Office of the Washington State Climatologist’s Guillaume Mauger and Karin Bumbaco provide expertise, tools and resources on “all things climate” to partners and communities across the state.

NASA has awarded a five-year, $2.5 million grant to establish a regional scientific consortium based at the University of Washington, in partnership with Washington State University and the Pacific Northwest National Laboratory. The consortium will use an interdisciplinary approach to explore how the space environment — both in low-Earth orbit and beyond — affects living things.

Chelsea Wood, a University of Washington associate professor of aquatic and fishery sciences, has an upcoming children’s book titled “Power to the Parasites! Everything You (N)ever Wanted to Know About the Creepy Crawlies Hidden in Your Home, Your Food, Your Pets – and Maybe Even in You!” The book introduces kids to the world of parasitism.

A new study finds that rocky planets orbiting small stars do have the potential for stable, life-supporting atmospheres. The finding supports continued study of the TRAPPIST-1 system and other top candidates in the search for life outside our solar system.

Polar bears in some parts of the high Arctic are developing ice buildup and related injuries to their feet. The changes appear to be an unexpected consequence of climate change, related to changing conditions in a warming Arctic.

Researchers think meltwater beneath Martian ice could host microbial life. New results show that dusty ice could allow deeper layers to melt, while allowing enough sunlight through to support photosynthesis.
