Potential impacts of climate change on air quality and human health
A doubling of global atmospheric CO{sub 2} is predicted to increase the number and severity of tropospheric ozone episodes in four cities studied. The historical ozone record for Sacramento, CA, Chicago, IL, St. Louis, MO, and Los Angeles, CA was examined in terms of meteorological regimes conducive to ozone formation, using the Classification and Regression Tree (CART) technique. Subsequently, the meteorological regimes predicted by the Regional Climate Model (RegCM) when embedded in a global climate model were compared for a base-case simulation and a simulation with doubled CO{sub 2} concentrations to the historical CART analysis. Doubled CO{sub 2} lead to simulated higher daily temperatures, and this effect dominated the meteorological correlations with high tropospheric ozone concentrations. The health effects, and costs associated with these effects, were quantified for each of the four cities in terms of premature mortality, hospital admissions for respiratory diseases, and respiratory symptoms.
