Air pollution is the main environmental cause of early death, and new research from experts in Canada and the United States finds that, in about 75 years, climate change will see the number of air quality alerts in the U.S. to quadruple.
Air pollution is the main environmental cause of early death, and new research from experts in Canada and the United States finds that, in about 75 years, climate change will see the number of air quality alerts in the U.S. to quadruple. As alerts increase, inequalities for those unable to adapt to protect their health will intensify.
Researchers from the University of Waterloo led the study that found that by 2100, people would need to stay indoors an additional 142 days per year to avoid additional health risks from intensifying air pollution. The increase is expected to be greatest in the eastern half of the U.S. People who are unhoused or who live in homes that allow in polluted air wouldn’t get the same health protections. Currently, only between 15 to 20 per cent of people in the U.S. restrict outdoor activity when recommended.
“We saw conditions for alerts most often in areas of high Black populations, higher incomes, and leakier homes, deepening inequalities between residents who can access clean indoor air and those in the same area who cannot,” said Dr. Rebecca Saari, an associate professor at the Department of Civil and Environmental Engineering at Waterloo and senior author of the study, which also included Dr. Chris Bauch from the Faculty of Mathematics.
