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.”

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.

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…

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.

Charles Eriksen, Deborah Kelley and Stephen Warren are among 60 newly elected fellows from U.S. and international institutions.
July 5, 2016
A long-term Pacific climate cycle may be driving the expansion of Antarctic winter sea ice since 2000, but a new study finds that the trend may soon reverse.
May 3, 2016
Dennis Hartmann, a UW professor of atmospheric sciences, was elected as a member of the National Academy of Sciences.
April 6, 2016
From a tiny island halfway between New Zealand and Antarctica, scientists hope to learn more about the physics of clouds above the stormy, inhospitable Southern Ocean.
March 9, 2016
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.
February 23, 2016
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.
January 29, 2016
Satellite data show that the moon’s gravity puts a slight damper on rainfall on Earth.
January 26, 2016
A new model explains the fundamental features of the Madden-Julian Oscillation, which some scientists predict will be the “next El Nino.”
January 20, 2016
Two University of Washington teams claimed top prizes in a national competition to design a game about climate adaptation.
January 11, 2016
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…

UW scientists will give free talks on climate change for three consecutive Saturdays at Mt. Baker Ski Area.
December 9, 2015
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.
November 23, 2015
Four University of Washington researchers are among 347 new fellows of the American Association for the Advancement of Science for 2015.
November 11, 2015
With high-tech weather radars, weather balloons, ground instruments and NASA’s DC-8 flying laboratory, scientists will be watching rain and snow storms on Washington’s famously wet Olympic Peninsula.
July 17, 2015
New research led by the University of Washington and the Pacific Northwest National Laboratory suggests tiny ocean life in vast stretches of the Southern Ocean plays a significant role in generating brighter clouds overhead.
April 9, 2015
A patch of warm water off the West Coast, nicknamed “the blob” by a UW scientist, is part of a larger shift in the Pacific Ocean that may be responsible for widespread weather changes.
April 2, 2015
The University of Washington and NASA are preparing for an effort next winter to measure rain in America’s rainiest place: Washington’s Olympic Peninsula. As part of the current gear-up phase, they are looking for volunteers to help track rain.
February 20, 2015
A UW atmospheric scientist is leading a six-week survey of eastern U.S. skies to see how winter conditions affect air quality.
January 8, 2015
University of Washington scientists published the first large-scale survey of impurities in North American snow. An almost 10,000-mile road trip showed that disturbed soil often mattered as much as air pollution for the whiteness of the snow.
November 10, 2014
Instead of carbon dioxide, or CO2, creating a blanket that slowly warms the planet, long-term warming happens because a darker surface and more moist air can absorb more of the incoming rays.
August 28, 2014
UW atmospheric scientists David Battisti and Qiang Fu have been elected fellows of the American Geophysical Union.
August 21, 2014
Observations show that the heat absent from the Earth’s surface is plunging deep in the north and south Atlantic Ocean, and is part of a slow, naturally recurring cycle.
May 7, 2014
Up to half of the recent warming in Greenland and surrounding areas may be due to climate variations that originate in the tropical Pacific and are not connected with the overall warming of the planet. Still, at least half the warming remains attributable to global warming caused by rising carbon dioxide emissions.
April 11, 2014
Detailed ice core measurements show smog-related ratios leveling off in 1970, and suggests these deposits are sensitive to the same chemicals that cause acid rain.
February 26, 2014
German, Finnish and U.S. scientists have discovered how gas wafting from coniferous trees creates particles that can reflect sunlight or promote formation of clouds.
February 18, 2014
Carrying out geoengineering for several decades and then stopping would cause warming at a rate more than double that expected due to global warming.
December 17, 2013
A special interdisciplinary issue of the journal Climatic Change includes the most detailed description yet of the proposed Oxford Principles to govern geoengineering research, and surveys the technical hurdles, ethics and regulatory issues related to deliberately manipulating the planet’s climate.

Atmospheric scientist Dan Jaffe tonight will present the first results of a crowd-funded study of train emissions, conducted with four undergraduates from the Seattle and Bothell campuses and funded by public donations.
