Climate change threatens air quality
New modelling shows almost one in three Americans will routinely breathe air considered unhealthy for sensitive people by the year 2100 due to climate change, a sevenfold increase compared to the turn of the century.
The international study, led by the University of Waterloo, found that about 100 million people in the United States will live in areas where average air quality during smog season is poor enough to trigger alerts advising vulnerable people to stay indoors.
