In North America, tens of millions of people awoke to hazardous air quality as catastrophic wildfires raged throughout Canada.
On Tuesday and Wednesday, a large portion of Ontario and Quebec were obscured by smoke, while the majority of the northeastern US was shrouded in an orange haze.
Toronto and New York saw some of the worst air quality in the world last night.
The 160 fires that are raging in Quebec are responsible for a large portion of the smoke.
The worst wildfire season on record is expected, according to Canadian officials.

There are four ways that climate change is affecting the weather.
The Northeast’s air quality was deemed by the US Environmental Protection Agency (EPA) to be “unhealthy,” particularly for those who already have respiratory issues.
In North America, it’s estimated that 100 million people are now under some kind of air quality alert.
Icons like the Statue of Liberty were difficult to view in New York due to an orange haze that obscured the city’s skyline.

Detroit was listed by IQAir as the fifth most polluted city in the world on Wednesday morning, while the air quality in the Washington, DC, region was deemed to be in “code red.”
Public health officials have advised people to avoid exercising outdoors and to remain as far away from the smoke as possible. This is such that both immediate and long-term health dangers are present in the air.
People with asthma and other respiratory issues had to be moved away from the smoke in the Atikamekw community of Opitciwan, 350 km (217 miles) north of Montreal, since the air quality was deteriorating.
In Canada, wildfires have already consumed more than 3.3 million hectares of land. The area burnt this time of year was 12 times more than it typically been during the previous 10 years.
People have been instructed to evacuate their houses throughout the nation.
Along with Quebec, there are also significant fires burning in British Columbia, Alberta, Ontario, Nova Scotia, and the Northwest Territories.
The likelihood that it will be hot and dry, which may lead to wildfires, is increasing due to climate change.
The globe has already warmed by around 1.2C since the start of the industrial age, and temperatures will continue to increase unless governments all over the world drastically reduce their emissions.
How is the health affected by wildfire smoke?
According to experts, being near wildfire smoke may result in a wide range of health issues.
Shortness of breath, a rapid heartbeat, chest discomfort, or irritation in the eyes, nose, or throat are some of the acute side effects of breathing in wildfire smoke, according to Matthew Adams, a professor at the University of Toronto and the director of its Centre of Urban Environments.
According to Prof. Adams, more individuals will visit the hospital on days with significant air pollution. And the majority of patients who visit the hospital already have a respiratory condition, she said.
According to Prof. Adams, long-term health issues including cancer and lung illness have also been related to wildfire smoke, particularly in persons who live in areas where forest fires occur often.
He said that this is the result of tiny particles in the smoke cloud. DNA alterations and other health issues may result from these particles entering the circulation and other bodily regions.
Additionally, some studies have shown that prolonged exposure to wildfire smoke might have negative effects on pregnant women and their unborn children.
Prof. Adams advised residents in communities that are distant from the flames but are still receiving air quality warnings to restrict their outdoor activities in order to avoid breathing in fire smoke.
Don’t stress about it too much, he advised her. “Stay inside for your own safety.”
Prof. Adams advised wearing a N95 mask outdoors in areas where the flames were closer so people wouldn’t breathe in as much smoke.
