Expect '21st-century fires,' says author John Vaillant

Though Maine was spared the worst of it, many areas in the Northeast U.S. have been blanketed by smoke from Canadian wildfires in recent weeks. A new book suggests this may become more common phenomenon. In "Fire Weather," author John Vaillant chronicles a major wildfire in Fort McMurray, Alberta, that forced a major evacuation, and shut the petroleum-producing city down for a month in 2016. Vaillant said he believes that climate conditions will generate more of these fires in the decades to come.
