This was evidenced last year, when smoke from Canadian
wildfires drifted over the North Pole, and the year before when Fort McMurray was devastated by wildfires (and don't forget Siberia then, too), and the year before, when it was Alaska's turn to burn, and well, you get the point.
Researchers caught what they say are the first direct images of
wildfire smoke
drifting over Greenland this past summer with NASA's Cloud - Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) satellite, which they presented this week at the annual meeting of the American Geophysical Union in San Francisco.
