Canadian wildfire smoke drifts 4,800 km to Norway

Earlier this week, smoke drifted across the Canadian border into the United States, blanketing cities on the East Coast, giving New York the worst air quality of any major city in the world. Over the past week, winds have carried smoke from wildfires across Greenland and Iceland to Norway, where it was first detected on June 7. However, the concentration of smoke in Norway is relatively low, according to scientists from the Norwegian Institute for Climate and Environmental Research (NILU).

“When the smoke reaches Europe, the particle count is much lower,” said Nikolaos Evangeliou, a senior scientist at NILU. “This means we can see the smoke as a light mist, and we can notice the smell of smoke. But the particle count is so low that it does not pose a health risk.”

According to NILU's prediction model, based on data from the US National Weather Service's Global Forecast System, the smoke is likely to drift across Norway and into southern Europe.

More than 3.8 million hectares of land, about a quarter the size of New York, have burned in Canada since the start of the year, said Bill Blair, the federal minister of emergency preparedness. That puts Canada on course for its worst wildfire season on record.

“The distribution of fires on both sides of the coast this year is very unusual,” said Michael Norton, an official with Natural Resources Canada. “At this time of year, fires are usually on one side of the coast, mainly the west coast.”

While pollution from the wildfires poses little threat to Europeans’ health, high levels of fine particles in the smoke in cities across the US East Coast can cause respiratory problems such as coughing and shortness of breath. Health officials in New York and Washington DC have advised people in affected cities to limit outdoor activities until the smoke has dissipated to safe levels.
