Climate change has the potential to significantly affect human exposure to pollutants in indoor environments. This includes: i) increased use of air conditioning in both residential and commercial buildings, reducing air exchange rates and increasing concentrations of pollutants with indoor sources; ii) increased emission rates of organics from furnishings and building materials due to elevated temperatures; iii) increased occurrence of indoor ozone-initiated chemistry due to rising outdoor ozone concentrations; iv) increased chemistry due to increased reaction rates at higher temperatures; and v) more time spent indoors due to less hospitable outdoor conditions. It is these and other connections with human exposure to pollutants that form the nexus between Weschler’s research and climate change.
