I've heard, although I can't find confirmation of it at the moment, that this has happened on occasion at airports in Alaska where, being much closer to the pole, the heading to magnetic north is changing more rapidly.

- macrael 16y agoThe rate of change of magnetic north varies wildly around the world, not based on latitude. See this fabulous .gif on Wikipedia http://en.wikipedia.org/wiki/File:Earth_Magnetic_Field_Declination_from_1590_to_1990.gif http://en.wikipedia.org/wiki/File:Earth_Magnetic_Field_Decli...
- gregable 16y agoThat's fascinating - I always thought it was based on latitude - basically the difference in angle between the north pole and the magnetic north pole. Still though, even in that animation, Tampa seems pretty stable over time.
