Climate change could significantly worsen summer air quality in future decades
Even in Canada, where air pollution is generally considered a low risk, more than 17,000 early deaths and over $140 billion in economic damages each year are linked to it. Pollution from heavy industry or wildfires, for example, can make outdoor air so polluted that it poses immediate health risks. Climate change can worsen air quality as changes to temperature, winds and rainfall enhance emissions, accelerate their transformation and allow them to build up to unhealthy levels.
