Assessment of the Impacts of Global Change on Regional U.S. Air Quality: A Synthesis of Climate Change Impacts on Ground-Level Ozone

This report, released in April 2009 by the U.S. EPA’s Global Change Research Program, is intended to provide managers and scientists working on air quality with information on the potential effects of climate change on regional air quality in the U.S. The report summarizes results from the assessment’s first phase, which focused on the development of regional modeling tools that demonstrate the sensitivity of air quality to climate change, with a particular emphasis on summertime ozone.  These modeling tools incorporate the physical and chemical links between global- and regional-scale meteorological processes to project future regional air quality, and account for changes in energy and transportation technologies in future air quality-related emissions. 

The report concludes that climate change by 2050 and beyond should be considered by air quality managers as they develop air pollution control strategies.
