Greenland melting due equally to global warming, natural variations

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.

Citizen scientists: UW students help state legislator with climate policy

Four graduate students were part of a year-long legislative process in Olympia working to reduce greenhouse-gas emissions in Washington state.

Embarking on geoengineering, then stopping, would speed up global warming

Carrying out geoengineering for several decades and then stopping would cause warming at a rate more than double that expected due to global warming.

Greenland’s fastest glacier sets new speed record

Observations of Jakobshavn Glacier from 2012 and 2013 show the fast-moving glacier has set new records for the speed of ice flowing toward the ocean.

El Niño tied to melting of Antarctica’s Pine Island Glacier

A new study in Science, co-authored by the British Antarctic Survey and UW authors, shows that melting of the floating Pine Island ice shelf is tied to global atmospheric patterns associated with El Niño.

Hack the planet? Geoengineering research, ethics, governance explored

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.

What climate change means for federally protected marine species

As the Endangered Species Act nears its 40th birthday at the end of December, conservation biologists are coming to terms with a danger not foreseen in the 1970s: global climate change.

More wildfires, earlier snowmelt, coastal threats top Northwest climate risks

A new comprehensive report co-authored by the UW’s Climate Impacts Group looks at what climate change will mean for Washington, Oregon and Idaho.

Redwood trees reveal history of West Coast rain, fog, ocean conditions

Scientists found a way to use coastal redwood trees as a window into historic climate, using oxygen and carbon atoms in the wood to detect fog and rainfall in previous seasons.

Global ocean currents explain why Northern Hemisphere is the soggier one

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.
