Winter air campaign tracking how pollution handles the cold

A UW atmospheric scientist is leading a six-week survey of eastern U.S. skies to see how winter conditions affect air quality.

Epic survey finds regional patterns of soot and dirt on North American snow

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.

Global warming not just a blanket – in the long run, it’s more like tanning oil

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.

Cause of global warming hiatus found deep in the Atlantic Ocean

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.

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.

Greenland ice cores show industrial record of acid rain, success of U.S. Clean Air Act

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.

Pine forest particles appear out of thin air, influence climate

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.

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.

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.
