Las tormentas limpiarán el humo de los incendios forestales del noreste antes de la final de la Copa del Mundo, dicen los meteorólogos

Canadian wildfires have sent hazardous smoke drifting across the border into the United States, exposing millions of people to dangerously high levels of air pollution. On Thursday, out-of-control blazes raged in the Canadian province of Ontario, creating a thick haze that spread into neighboring U.S. states, including Minnesota, Wisconsin, Michigan, Illinois, and parts of the Northeast. The smoky conditions led to severe air quality issues, prompting health warnings and emergency measures in affected regions. The situation reached critical levels in major urban centers. According to IQAir’s tracking system, Minneapolis, Detroit, and Chicago ranked among the most polluted cities globally on Thursday afternoon. In New York, a dense haze blanketed the metropolitan area, with officials issuing alerts about harmful fine particulate matter. The city’s air quality index (AQI) hit dangerous levels, with the Department of Emergency Management warning that conditions might worsen. Mayor Zohran Mamdani described the scenario as a “serious threat,” urging residents to limit outdoor activity due to extreme heat and poor air quality. Across the Midwest, the impact was equally severe. The U.S. Environmental Protection Agency reported that many locations, including Chicago, Toledo, Ohio, and parts of Minnesota, had AQI readings exceeding 700—a level classified as “hazardous.” These figures dwarfed the 465 recorded during New York’s similarly dire 2023 smoke event. In response, local governments activated contingency plans, opening hundreds of cooling centers and distributing free face masks to the public. Farmers in Wisconsin, such as Erin Lucey, who manages an organic vegetable farm, faced challenging working conditions. She described the combination of smoke, heat, and dry fields as “eerie,” emphasizing the strain on agricultural operations and the broader implications for climate resilience. In Michigan, environmental authorities projected that hazardous conditions would persist through Friday. Their models suggested some improvement by Saturday, though smoke was expected to linger and circulate for several days. The state’s Department of Environment, Great Lakes, and Energy noted that current forecasts only extend 48 hours, highlighting the uncertainty in predicting the event’s duration. Meanwhile, in Canada, the situation remained volatile. Over 130 wildfires were burning in northwestern Ontario, with at least 60 considered out of control. Authorities have sought federal aid, particularly requesting air support to assist with evacuations in remote communities. Ontario Provincial Police confirmed that 15 communities and surrounding areas had been evacuated. Premier Doug Ford announced that more than 150 fire crews and nearly 50 firefighting aircraft were deployed to combat the blazes. Despite these efforts, the scale of destruction continues to grow. This year, Canadian wildfires have consumed at least 1.9 million hectares, an expanse roughly equivalent to the nation of Slovenia. While this marks a significant increase compared to previous years, it still falls short of the record-breaking 18 million hectares burned during the country’s worst wildfire season in 2023. As the smoke continues to drift across borders, both nations grapple with the immediate health risks and long-term implications of escalating climate-related disasters. With temperatures rising and drought conditions worsening, the frequency and intensity of such events are expected to increase, posing ongoing challenges for public health, agriculture, and emergency management systems.
