Ever since the compass was invented, navigators have noticed that the direction indicated by the needle changes slightly each year. Over the last century, both the north and south magnetic poles have been drifting north (that is, toward the geographic north pole, which itself wanders somewhat, but let's not make this more complicated than it already is). The north magnetic pole historically has moved at a rate of about ten kilometers per year, but has lately accelerated, heading toward Russia at four times that rate.
ANyone have any clues or good support evidence into when this would occur?
