David Battisti, Qiang Fu elected AGU fellows

UW atmospheric scientists David Battisti and Qiang Fu have been elected fellows of the American Geophysical Union.

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.

UW Bothell prof, students present crowd-funded study of coal train emissions

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.

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.

UW researchers helped draft international assessment of climate change

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.
