![]() Certain weather situations provide the requisite meteorologic conditions for pollution episodes. ![]() 2004 Hazenkamp-Von Arx 2004 Kassomenos et al. Some air pollutants demonstrate clear seasonal cycles ( Alvarez et al. Some locations, because of their general climate and topographic setting, are predisposed to poor air quality because the climate is conducive to chemical reactions leading to the transformation of emissions, and the topography restricts the dispersion of pollutants ( Kossmann and Sturman 2004 Rappengluck et al. 2007).Īir pollution concentrations are the result of interactions among local weather patterns, atmospheric circulation features, wind, topography, human activities (i.e., transport and coal-fired electricity generation), human responses to weather changes (i.e., the onset of cold or warm spells may increase heating and cooling needs and therefore energy needs), and other factors. ![]() We limited our review to the past several years because of significant advances in climate modeling ( Solomon et al. Therefore, we review studies projecting the impacts of climate change on air quality and studies projecting the impacts of these changes on morbidity and mortality, with a focus on studies published since 2000. Worldwide in the year 2000, 0.8 million deaths and 7.9 million disability-adjusted life-years lost from respiratory problems, lung disease, and cancer were attributed to urban air pollution ( World Health Organization 2002).īecause the state of the atmosphere at various scales determines the development, transport, dispersion, and deposition of air pollutants, there is concern that climate change could affect the burden of illness and mortality associated with these gases and fine particles. ![]() Extensive literature documents the adverse health impacts of exposure to elevated concentrations of air pollutants, particularly ozone, particulate matter with aerodynamic diameters <10 (PM 10) and < 2.5 μm (PM 2.5), sulfur dioxide, nitrogen dioxide, carbon monoxide, and lead. ![]()
