Key Points Question What is the association of reducing air pollutant emissions with the human health burden associated with climate change? Findings In this modeling study, projected changes in climate and concentrations of ozone (O3) and particulate matter smaller than 2.5 μm in diameter (PM2.5) were estimated over the 21st century under a high–greenhouse gas scenario using 2 climate models and 2 air pollutant emission data sets. The substantial increases in estimated air pollution–attributable mortality associated with climate change were projected to decline if air pollutant emissions were reduced. Meaning These findings suggest that reducing air pollutant emissions could attenuate but not eliminate the climate change-induced increase in mortality associated with air pollution.
