Norwegian officials said smoke from Canadian wildfires that have shrouded parts of the US and Canada in thick fog is expected to reach in Norway within the day.

Scientists at the Norwegian Institute for Climate and Environmental Research (NILU) used a forecast model to estimate how the smoke would travel through the atmosphere. Smoke has moved over Greenland and Iceland since June 1, and observations in southern Norway have recorded increasing concentrations of particles, the independent research institute said.

“We might be able to see some fog or smell smoke,” said Mr Nikolaos Evangeliou, NILU senior researcher. However, he pointed out, we do not believe that the number of particles in the air here in Norway will be high enough to be harmful to our health.

The US East Coast is facing dangerous levels of air pollution from wildfires burning in Canada. The smoke has affected millions of people, canceled flights at major airports, postponed major league baseball games and made Americans remember pandemic-era masks again. Canada has asked for help to fight more than 400 fires across the country.
