Drainage of four interconnected lakes below Thwaites Glacier in late 2013 caused only a 10 percent increase in the glacier’s speed. The glacier’s recent speedup is therefore not due to changes in meltwater flow along its underside.

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…

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.

Polar oceans pump organic carbon down to the deep sea about five times as efficiently as subtropical waters, because they can support larger, heavier organisms. The finding helps explain how the oceans may function under climate change.

Scientists from the University of Washington have found evidence that ocean acidification caused by carbon emissions can prevent mussels attaching themselves to rocks and other substrates, making them easy targets for predators and threatening the mussel farming industry.

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 30, 2016
The waters surrounding Antarctica may be one of the last places on Earth to experience human-driven climate change, because of its unique ocean currents.

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.
April 20, 2016
As the U.S., China and other countries sign the Paris Agreement to reduce emissions and limit climate change, UW experts talk about the possibilities and risks in what could be a turning point for global economies.

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.

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.
January 20, 2016
Two University of Washington teams claimed top prizes in a national competition to design a game about climate adaptation.
December 10, 2015
Two University of Washington researchers have uncovered details of the radically divergent strategies that two common tree species employ to cope with drought in southwestern Colorado. As they report in a new paper in the journal Global Change Biology, one tree species shuts down production and conserves water, while the other alters its physiology to continue growing and using water.

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.

A new report by the University of Washington synthesizes all the relevant research about the future of the Puget Sound region to paint a picture of what to expect in the coming decades, and how to prepare.
November 12, 2015
When President Barack Obama visited the shrinking Exit Glacier in September, he pointed to a very obvious sign of our warming planet literally at his feet. Less visible, but perhaps more indelible, signs of changing climate lie in the oceans. A University of Washington researcher argues in the journal Science that people — including world…

A UW graduate student’s research paper is the first serious study of whether climate change is likely to cause human migration to the Puget Sound region.
September 14, 2015
New research from the University of Washington’s Friday Harbor Laboratories shows that a more acidic ocean can weaken the protective shell of a delicate alga. The findings, published Sept. 9 in the journal Biology Letters, come at a time when global climate change may increase ocean acidification.
July 6, 2015
Despite worries about interbreeding due to climate change, a new study finds that only about 6 percent of closely related species in the Americas are likely to come into contact by the end of this century.
March 3, 2015
Historic submarine and modern satellite records show that ice thickness in the central Arctic Ocean dropped by 65 percent from 1975 to 2012. September ice thickness, when the ice cover is at a minimum, dropped by 85 percent.

Historic observations and NASA airborne data provide a decades-long record showing that the snowpack on Arctic sea ice is thinning.

Piles of ancient shells provide the first reliable long-term record for the powerful driver of year-to-year climate changes. Results show that the El Niños 10,000 years ago were as strong and frequent as they are today.

Predictions that the lowest-oxygen environments in the ocean will get worse may not come to pass. UW research shows climate change, by weakening the trade winds, will shrink these extremely low-oxygen waters.

An international team has placed sensors on and under Arctic sea ice to monitor this season’s retreat. Scientists hope to understand the physics of the ice edge in order to predict summer conditions in the Arctic Ocean.

Many have assumed that warmer winters as a result of climate change would increase the growth of trees and shrubs because the growing season would be longer. But shrubs achieve less yearly growth when cold winter temperatures are interrupted by temperatures warm enough to trigger growth.
May 12, 2014
The collapse of the West Antarctic Ice Sheet has begun, according to computer models using detailed topographic maps. The fast-moving Thwaites Glacier will likely disappear in a matter of centuries, researchers say, raising sea level by nearly 2 feet.

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.
