Winds carrying smoke from 200 Canadian wildfires covering a million acres are currently causing serious air pollution in major US cities over a region at least from Philadelphia to New York City. What was the cause of these fires?

This was another outing of the Mercenary Army Program to start wildfires that would spread and cause considerable damage. This they do in many parts of the world, particularly when there are dry conditions that make it difficult for humans to contain the fires once underway, and that contributes as well to the cover story, that it is all simply a "natural event" and inevitable as being weather-related and a potential risk, always, with drought, high temperatures, and so on, presumed falsely, to be caused by climate change.
