Heavier snowfall over Antarctica was supposed to be one of the few brakes on sea-level rise in a warming world. But that prediction is not reliable, says a new study of Antarctic snowfall over the past 31,000 years.

University of Washington students, faculty and staff are part of the fifth West Coast Ocean Acidification Cruise that will investigate changes to ocean chemistry from Baja to British Columbia. The ship left Thursday from San Diego to begin sampling on Mexico’s northern coast. It will stop May 21 at San Francisco’s Exploratorium Pier, then travel as far as northern Vancouver Island before ending in Seattle in early June. Follow along with the blog, which is being coordinated from shore by…

The idea that the young Earth had a thicker atmosphere turns out to be wrong. New research from the University of Washington uses bubbles trapped in 2.7 billion-year-old rocks to show that air at that time exerted at most half the pressure of today’s atmosphere. The results, published online May 9 in Nature Geoscience, reverse the commonly accepted idea that the early Earth had a thicker atmosphere to compensate for weaker sunlight. The finding also has implications for which gases…

Dennis Hartmann, a UW professor of atmospheric sciences, was elected as a member of the National Academy of Sciences.

Most of the world’s wild fisheries could be at healthy levels in just 10 years, and global fish populations could greatly increase by 2050 with better fishing approaches, according to a new study co-authored by University of Washington researchers.

A tally of Northern Hemisphere marine heatwaves since 1950 shows that prolonged warm periods have recurred regularly in the past, but are being pushed into new territory by climate change.

Alison Duvall talks about the geology of the UW light rail station in a narration to accompany the station’s art installation, which was created by UW alumnus Leo Saul Berk.

Construction started this month on the Washington Park Arboretum’s new Arboretum Loop Trail, one of the largest improvement projects to date in the Seattle public garden.

University of Washington oceanographers track 2,000 years of El Niño history, showing that it can shift in strength for centuries at a time.

UW researchers have developed a new method to track how wetlands in Eastern Washington behave seasonally, which will also help monitor how they change as the climate warms.

The UW’s School of Environmental and Forest Sciences is hosting its second-annual contest for undergraduate and high school students in Washington to create videos about what climate change means to them, in three minutes or less.

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.

A University of Washington team won first place in a science communication video contest that culminated during the recent Ocean Sciences Meeting.

Investigate a real ice core from Greenland, survey microbes from the coldest parts of the world, explore an Arctic ice camp and meet with polar scientists – many of whom are from the University of Washington. It’s all part of Polar Science Weekend, returning to Seattle’s Pacific Science Center March 4-6. The three-day event features interactive exhibits and opportunities to talk with top polar scientists who work in some of the most remote and challenging places on Earth. New this…

Just like a strong financial portfolio contains shares from different companies, the diverse subpopulations of herring from different bays and beaches around Puget Sound collectively keep the total population more stable, a new study finds.

Small disturbances, like the flapping of a butterfly’s wings, don’t really matter for weather forecasts. More important is boosting the accuracy of observations at larger scales.

UW glaciologists helped drill the first deep ice core at the South Pole, which will provide new clues to Antarctica’s climate history.

A new program based at the University of Washington will bring together educational institutions, K-12 teachers and informal education organizations to inspire, teach and recruit the next generation of students in science, technology, engineering and mathematics. The new Northwest Earth and Space Sciences Pipeline, or NESSP, has begun a $10 million, five-year cooperative agreement with NASA that broadens existing programs and launches new efforts throughout Washington, Oregon and Montana, with a particular focus on underserved and underrepresented communities. “The goal is…

As the Arctic continues to change due to rising temperatures, melting sea ice and human interest in developing oil and shipping routes, it’s important to understand belugas’ baseline behavior, argue the authors of a new paper.

The Center for Coastal Margin Observation and Prediction, through its education partner the University of Washington, is deploying an oceanographic observing buoy in Bellingham Bay this week that will allow Northwest Indian College students both hands-on experience with the technology as well as the ability to study the data from their computers, through the Northwest Association of Networked Ocean Observing Systems, NANOOS.

The UW is among West Coast universities awarded new funding to further develop ShakeAlert, an earthquake early warning system for the region.

A University of Washington study looked at potential risks associated with growing vegetables in urban gardens and determined that the benefits of locally produced vegetables in cities outweigh any risks from gardening in contaminated soils.

UW seismologist John Vidale will participate in a White House summit focusing on national earthquake preparedness.

Satellite data show that the moon’s gravity puts a slight damper on rainfall on Earth.

A new model explains the fundamental features of the Madden-Julian Oscillation, which some scientists predict will be the “next El Nino.”

Two University of Washington teams claimed top prizes in a national competition to design a game about climate adaptation.

First-time visitors and regulars to Washington Park Arboretum can now learn the names and origins of plants as well as save favorites while strolling through the grounds.

A new University of Washington study finds that urban crops in Seattle could only feed between 1 and 4 percent of the city’s population, even if all viable backyard and public green spaces were converted to growing produce.

Researchers have found clear evidence that communities rich in species are substantially healthier and more productive than those depleted of species, once complicating factors are removed.

What some have called the “Godzilla El Niño” is now lumbering ashore, right on schedule. El Niño tends to influence North American weather after the first of January, and indeed, we’re seeing warm temperatures in Alaska and much-needed rain in California. University of Washington researchers are tracking what the season will deliver to the Pacific Northwest region. For Washington, El Niño typically brings warm, and often dry, winter weather. That may seem surprising, since the state just experienced a very…

Along the West Coast, ocean acidification and hypoxia combine with other factors, such as rising ocean temperatures, to create serious challenges for marine life, a new study finds.

UW scientists will give free talks on climate change for three consecutive Saturdays at Mt. Baker Ski Area.

The large, fast-moving mudslide that buried much of Oso, Washington in March 2014 was the deadliest landslide in U.S. history. Since then it’s been revealed that this area has experienced major slides before, but it’s not known how long ago they occurred. University of Washington geologists analyzed woody debris buried in earlier slides and used radiocarbon dating to map the history of activity at the site. The findings, published online Dec. 22 in the journal Geology, show that a massive…
