The smoke from wildfires in eastern Canada has reached all the way across the Atlantic Ocean to Norway, more than 3,000 miles (4,800 kilometers) away.
Earlier this week, the haze crossed the Canadian border into the U.S., enveloping East Coast cities in smoke; New York City had the worst air quality of any major city in the world Wednesday (June 7). Throughout the week, wind has also carried this smoke across Greenland and Iceland into Norway, where it was first detected on Wednesday. However, the concentrations of smoke in Norway are "very weak," scientists from the Climate and Environmental Research Institute in Norway (NILU) told French news agency AFP.
