Oceanographers from the 91探花and NOAA deployed a new tool that will automatically test for harmful algal blooms and help warn of when they could hit local beaches.
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.
91探花 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 91探花 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 91探花professor of atmospheric sciences, was elected as a member of the National Academy of Sciences.

What some have called the “Godzilla El Ni帽o” is now lumbering ashore, right on schedule. El Ni帽o 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. 91探花 researchers are tracking what the season will deliver to the Pacific Northwest region. For Washington, El Ni帽o typically brings warm, and often dry, winter weather. That may seem surprising, since the state just experienced a very…
91探花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. 91探花 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…
It took 100 million years for oxygen levels in the oceans and atmosphere to increase to the level that allowed the explosion of animal life on Earth about 600 million years ago, according to a study co-authored by two 91探花 scientists and led by the University College London.
When an earthquake struck Nepal in late April 2015, thousands of lives were lost in the initial disaster. But it was hard to assess the scale of the damage to rural areas, and still lurking were threats from unstable slopes and dammed glacier-fed lakes that could dislodge at any time to flood villages below. A 91探花 Tacoma faculty member was part of an international team of scientists who worked with government agencies and private companies on a massive…
The long, slow 2014 eruption of Iceland’s Bardarbunga volcano offers a testbed to show how sulfur emissions, from volcanoes or humans, act to brighten clouds and reflect more sunlight.
