US President Donald Trump threatened on Friday to increase tariffs on Canada to cover the costs of smoke pollution from wildfires that have choked large parts of the United States. Dense wildfire smoke from Canada and northern Minnesota has led to unhealthy air quality alerts across the US. Trump accused Canada of 'not properly maintaining' their forests and failing to carry out 'basic Forest Management and Debris Removal.'

## Impact on Air Quality

As of Saturday, there were 937 active fires in Canada, most of which were burning out of control, according to the Canadian Wildland Fire Information System. Detroit remained the most polluted city in the world on Friday, according to tracker IQAir. Washington and Chicago weren't far behind, and officials warned against spending unnecessary time outside. The pollution also triggered concern over the World Cup final on Sunday in an open stadium in New Jersey. Tournament organizers are closely monitoring the situation. Peter Mullinax, a meteorologist for the National Weather Service, said winds over the Great Lakes could push more smoke into the Northeast, though some improvement is expected. Joel Dreessen, an air quality forecaster for Maryland, noted that the issue for Sunday's game is whether more smoke spills south after weekend storm systems. In cities across the Midwest and Northeast, people wore masks outdoors to filter out the dangerous air. In New York, libraries and train stations were handing them out for free.

## Response and Criticism

Canada's emergency management minister Eleanor Olszewski said Canada and the United States were in 'constant contact,' pointing toward their 'long history of working together to fight wildfires.' She added that Canada has invested $12 billion in forest sustainability and fire prevention since 2020. Chris Carlsten, who studies the health impacts of fire smoke at the University of British Columbia, said the fine pollution particles from wildfires are particularly impactful on the lungs. Mark Parrington, a scientist at the Copernicus Atmosphere Monitoring Service, explained that climate change was providing conditions for a longer fire season, with higher surface air temperatures and lower soil moisture.

## Fire Situation in Canada and Minnesota

The blazes were worsening in Canada, especially in Ontario, according to authorities there. Fires in Ontario have not caused any casualties, and several remote communities have been evacuated, as dozens of aircraft battle the blazes. Meanwhile, 16 active fires were burning in the Superior National Forest, on Minnesota's border with Canada. The US forest service said the forecast for erratic weather, shifting winds and the potential for isolated damaging wind gusts and thunderstorms will be a challenge for firefighting efforts.
