Years ago I remember reading that the earth's magnetic poles have reversed themselves more than once, although presumably not during recorded history. Seems like this would be hard on birds as well as Boy Scouts.
I love that, with GPS, now we can watch the earth's tectonic plates move around relative to one another. Just don't have an EMP or a bad magnetic storm fry things, and we're good…

Maybe the Pole is trying for a better grade by moving closer to the geographic pole. Still won't help folks use a compass in Iron Mountain, MI.
Cut that shit out, Earth!
hey, you can still use Polaris.
Well, shit, if Blue posted this, I guess I'll have to post something obscure and musical.
Fuckin' magnetosphere, how does it work?

Just because I got that joke doesn't mean I should suffer because of it
