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.

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.

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.”
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.

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.
November 4, 2013
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.
October 20, 2013
A new study in Nature Geoscience explains a major feature of global precipitation, and shows how a current originating from the poles influences tropical rainfall in Africa and southern India.
September 30, 2013
UW faculty members were among international researchers who compiled the fifth climate-change assessment report. The UW will host a seminar Tuesday, Oct. 1 with some of the Seattle-area authors.
August 1, 2013
A UW atmospheric scientist is co-author of a review paper, published this week in the journal Science, looking at the ecological consequences of sea ice decline.
July 9, 2013
Dozens of atmospheric scientists, including three University of Washington faculty members, are taking part in what’s being described as one of the largest atmospheric field campaigns in decades.
June 6, 2013
Air pollution in the Northern Hemisphere in the mid-20th century cooled the upper half of the planet and pushed rain bands south, contributing to the prolonged and worsening drought in Africa’s Sahel region. Clean air legislation in the 1980s reversed the trend and the drought lessened.

Drops forming on the outside of your drink don’t just make the can slippery. Experiments show that in hot, humid weather, condensation heats a drink more than the surrounding air.
March 11, 2013
One of the most persistent biases in global climate models is due to poor simulation of cloud cover thousands of miles to the south.
February 28, 2013
Regional cloud changes may be as important for climate change as the overall amount of cloud cover.
February 6, 2013
Atmospheric scientists are using pressure readings from some new smartphones and tablet computers to improve short-term thunderstorm forecasts. A weather station in every pocket would offer an unprecedented wealth of data.

A new international assessment found that soot, or black carbon, is a major contributor to global warming — second only to carbon dioxide.

The Seahawks win four times as many home games as they lose when the weather is inclement, compared to less than two to one when it’s not.
