Canada's hellish wildfire season

Axios - Canada's wildfire season, already the worst on record, went "completely off the rails" during the past week, scientists tell Axios, Andrew writes. Enough land area burned during the last week to make the seven-day-period comparable to nearly an entire typical fire season across Canada, according to Merritt Turetsky of the University of Colorado. Not only have the fires displaced tens of thousands of Canadians this summer, but they have also caused historically poor air quality in the U.S.  With hundreds of wildfires still burning, there is the potential for more air quality degradation in the U.S. through the fall.
