North Pole is Leaving Canada

Dedekind writes: "CNN.com is posting this story on the drifting of the Magnetic North Pole. Not only is the pole shifting from a spot just North of Resolute, Canada, Canadian scientists expect it to end up in Siberia within the next half-century. Perhaps the most interesting part of the story (which really is only a small part at the end) is that many couples like to go to the magnetic North Pole to conceive their children. "

but if the poles just flipped, imagine what chaos it would cause

The orientation of the field doesn't really matter too much. I mean, we'd have to relabel compasses, etc., but no big deal.

But ... during the reversal, the magnetic field actually fades to (essentially) zero, and does so for a noticeable length of time. In that circumstance, the Van Allen Belts disappear and the surface no longer has its usual protection from solar wind, cosmic rays, etc. That's the time to worry.
