When many fires started at once in Quebec then people took that as evidence of arson, and their claims got millions of views online. These claims were debunked by meteorologist Wagstaffe who explained that a series of lightning strikes can cause many smouldering hotspots underneath rain-moistened surface fuels; and then when those surface fuels are all dried by the daytime wind simultaneously, then they are all ignited into full blown fires simultaneously. Wagstaffe also corrected the idea that controlled burns are state-sponsored arson.
