Smoke from Canadian wildfires hits air quality across U.S. Midwest and Northeast
The Canadian forest fire smoke triggers air quality warnings in the US Middle West and Northeast on Thursday, because the Boreal forests of the Northern nation continue to burn at an except for a historical season in 2023.
With the fires, smoke, ozone with the heat, Minneapolis, Green Bay, Indianapolis, Cincinnati, Columbus, Pittsburgh, Washington, Philadelphia and New York increased air pollution levels.
The fire season makes a roaring in Canada. According to the Forest Fire Brigade Center between Canada, about 8.6 million acres have been burned so far. The fire season is still three months away, the burning area is already above the seasonal average of Canada and has been about 6.5 million acres since 1983.
The combustion rate in Canada is a tendency similar to 2023, the worst year for smoke exposure in the history of modern US. Firefighters in Canada are concerned about the staging of the season for a report.
“Everyone has needles and needles waiting for a bad year up to 2023, Rob said Robert Gray, a Canadian forest fire -based Canadian -based Canadian -based Canadian. “For most of Canada, forecast is definitely normal for temperatures and below normal for rainfall.”
At the end of the season, about 43 million acres were burned in Canada that year.
Gray said that this year, most of the smoke was produced by British Columbia, Alberta and Saskatchewan’s intensive Boreal Forest in the northern regions. In May and June, when the Boreal regions are typically long and the temperatures begin to increase, the forest fire. What will happen later depends on the weather.
Gray, referring to the aspen trees that are common in these forests, Gray said, “Two weeks can be a fast beep. Boreal begins to burn, Aspen leaves starts to come out and then the weather is changing,” he said. “Rain with Aspen and if we don’t get out of leaves, it can only continue.”
According to BC Wildfire Service, some parts of the Northern British Kolumbia have been united in drought since 2022. In some parts of the province, “a great, difficult fires are an increasing possibility”.
Gray, drought, low winter snowfall and from season from season to season, “winter” fires increase, the factors that increase the likelihood of an intensive fire season, he said.
Winter fires, only in the spring to start again in the forest DUff and Peat underground burns through the winter continues during the winter.
Gray said, “We have fires that started in 2023 and stopped until 2024 in winter, Gr said. “Some of the same fires appeared this year.”
When the northern British kolumbi burns, the smoke from the fires is usually moved to the United States with a jet stream, which is an air strip that surrounds the northern hemisphere at a height and directs pressure changes and weather conditions.
Gray, “This is a highly structured pattern. It does not change much. As long as it burns in the middle and northern Boreal, this pattern will give smoke to the middle and northeastern USA,” he said.
Sometimes this smoke remains in the air, contributes to the hazy sky, but does not significantly reduce air quality on the ground. At other times, it puts people at risk.
Wildfire Smoke is a growing danger throughout the United States, and increasing exposure was carved in the progress of air pollution that lasted decades of the Clean Air Life.
Exposure to forest fire smoke can cause inflammation and weaken the immune system, especially when particles penetrate the lungs and blood circulation. This pollution may increase the risk of asthma, lung cancer or other chronic lung diseases in vulnerable groups such as elderly people, pregnant people, babies and children. Wildfire smoke is also associated with respiratory disease, premature birth and miscarriage.
