UMD AOSC Seminar
Air Quality in a Changing Climate
Dr. Darrell Winner
Environmental Protection Agency
National Center for Environmental Assessment
Dr. Winner will discuss the rising challenge of meeting clean air goals in a changing climate. The complex interactions between air quality and climate change will be explored through 1) the climate penalty on ground-level ozone air pollution and 2) black carbon links between air pollution and climate, and the potential for dramatic improvements in public health for the poor.
Climate change could lead to significant increases in ozone levels and dramatically extend the length of the ozone season. There is growing evidence of this climate penalty, where rising temperatures boost levels of pollutants like ozone. Current and future regulations are expected to reduce air pollution emissions, but the climate penalty will reduce the benefit of these emission reductions.
Black carbon emissions are part of particulate matter air pollution which harms public health. This problem is especially severe for indoor exposures from cookstoves in the developing world. To help combat this problem, the EPA has joined the Global Alliance for Clean Cookstoves to improve air quality and human health around the globe. This is a great opportunities to slow climate change while improving global public health.
