I skimmed the article and was mostly surprised they didn't go into the whole pole-flipping thing, which I've definitely seen apocalyptic screeds about. It's a real thing, and is a valid concern, but as I recall it is not a point-in-time event like an earthquake, for instance. The Earth's magnetic field is kind of weird - it moves, and there are places where compasses won't work or reverse polarity. There is good long-term research on it thanks to the Royal Navy keeping meticulous records of compass readings from ships at sea, so we actually have a fair amount of data on it going back well over a century.
