Smoke from large wildfires in Canada and Minnesota has spread across much of the northern United States, affecting air quality for over 100 million people across the Midwest and eastern regions. The smoke has created hazardous air conditions, with health officials warning that exposure to wildfire smoke poses health risks comparable to smoking approximately half a pack of cigarettes per day. Several Major League Baseball games were affected by the poor air quality on Friday, with the Cleveland Guardians postponing their game and other teams closing retractable roofs to protect players and fans.
Health experts have provided recommendations for people to protect themselves during the period of poor air quality, including staying indoors when possible and using air purifiers. Resources have circulated about ways to create makeshift air purifiers at home using box fans. Air quality forecasts show the smoke beginning to move toward the eastern U.S., with warnings in place for millions of people until conditions improve.
President Trump stated on Friday that the U.S. would hold Canada responsible for the wildfires and threatened to impose additional tariffs on the country, claiming negligence in wildfire management. The smoke is also potentially affecting international events, with concerns raised about impacts on the World Cup final scheduled for New Jersey.
