Appearing in the journal Nature Climate Change, the study details the significant impact of climate change on global air pollution if nothing is done to address it.

"As climate change affects air pollutant concentrations, it can have a significant impact on health worldwide, adding to the millions of people who die from air pollution each year,” said Jason West, who led the research at UNC-Chapel Hill with former graduate student and first author Raquel Silva.

According to the researchers, as temperatures increase, the chemical reactions that create air pollutants like fine particulate matter and ozone accelerate, thereby impacting public health. Consulting several global climate models, West and Silva determined what that increase could mean in terms of the number of premature deaths linked to ground-level air pollution.

"Our finding that most models show a likely increase in deaths is the clearest signal yet that climate change will be detrimental to air quality and health," said West, associate professor of environmental sciences and engineering in the UNC Gillings School of Global Public Health. "We also collaborated with some of the world's top climate modeling groups in the United States, United Kingdom, France, Japan and New Zealand, making this study the most comprehensive yet on the issue.”

Researchers also advise against other issues linked to climate change, including its effect on health through changes in heat stress, access to clean water and food, severe storms and the spread of infectious diseases.
