Humo de incendios en Canadá llega a Nueva York; autoridades emiten una alerta por la calidad del aire

Smoke from wildfires raging in Canada's Ontario province reached New York on Thursday, prompting authorities to issue health advisories due to severely degraded air quality. The smoke, which had previously turned Toronto a sickly yellow, spread across the northern United States, affecting states near the Canadian border, including Minnesota, Wisconsin, Michigan, and Illinois. By late Thursday, cities such as Detroit, Minneapolis, and Chicago were ranked among the world’s most polluted locations according to data from the IQAir monitoring service. A thick haze covered New York City, with meteorologists predicting air quality levels classified as “health hazardous” due to fine particulate matter originating from the fires. Local officials urged residents to limit their time outdoors. Health alerts were issued in both New York and New Jersey ahead of Sunday’s World Cup final between Spain and Argentina, scheduled to take place at the MetLife Stadium in East Rutherford, New Jersey. The worsening conditions forced authorities in New York and New Jersey to provide guidelines for the public. In Detroit, Chicago, and Toledo, Ohio, air quality indices exceeded dangerous thresholds, according to the U.S. Environmental Protection Agency. Erin Lucey, a worker at an organic vegetable farm in southern Wisconsin, described feeling a sense of pressure in her chest, a symptom commonly associated with exposure to poor air quality. Officials in Michigan warned that these conditions could last through at least Friday. Recent reports indicate more than 130 active wildfires burning in northwest Ontario, with at least 60 of them currently out of control. Over 15 communities have been evacuated so far this year. Authorities in Ontario requested additional support from the federal government, particularly aerial assistance to evacuate remote areas. Prime Minister Justin Trudeau stated on Thursday that the government was prepared to offer all necessary additional support. Wildfires in Canada have scorched at least 1.9 million hectares this year, a figure lower than the record-breaking totals recorded in 2023 and 2025, according to official statistics. Despite the reduced area compared to previous years, the intensity and proximity of the current fires have raised concerns across the region. Residents in affected areas have been advised to stay indoors and avoid physical exertion outdoors. Schools and some businesses in parts of Michigan and Wisconsin have closed early or implemented indoor-only operations. Emergency services continue to monitor the situation closely, while environmental agencies track the movement of the smoke plumes using satellite imagery and ground-based sensors. In Toronto, where the sky turned an alarming shade of yellow earlier in the week, local officials have emphasized the need for continued vigilance. Firefighters and emergency personnel remain on high alert, preparing for potential shifts in wind patterns that could alter the trajectory of the smoke. Meanwhile, researchers are analyzing long-term trends in wildfire frequency and severity, linking them to climate change factors such as prolonged droughts and higher temperatures. Health experts warn that prolonged exposure to wildfire smoke can lead to respiratory issues, exacerbate existing medical conditions, and pose particular risks to children, the elderly, and individuals with pre-existing heart or lung diseases. Hospitals in affected regions have increased staffing and resources to handle potential influxes of patients seeking treatment for smoke-related ailments. Authorities in both Canada and the United States continue to coordinate efforts to manage the crisis, focusing on evacuation plans, public awareness campaigns, and air quality monitoring systems. As the situation evolves, further updates are expected from local governments and environmental protection agencies.
