Abstract

Air pollution is a key global environmental problem raising human health concern. It is essential to comprehensively assess the long-term characteristics of air pollution and the resultant health impacts. We first assessed the global trends of fine particulate matter (PM_2.5) during 1980–2020 using a monthly global PM_2.5 reanalysis dataset, and evaluated their association with three types of climate variability including El Niño-Southern Oscillation, Indian Ocean Dipole and North Atlantic Oscillation. We then estimated PM_2.5-attributable premature deaths using integrated exposure–response functions. Results show a significant increasing trend of ambient PM_2.5 during 1980–2020 due to increases in anthropogenic emissions. Ambient PM_2.5 caused a total of ∼ 135 million premature deaths globally during the four decades. Occurrence of air pollution episodes was strongly associated with climate variability, which were associated with up to 14 % increase in annual global PM_2.5-attributable premature deaths.
