I would really like to know about the North Pole's movement.
It too has a cyclic motion and the last I heard was that the North
Pole had reached Siberia
and showed no signs yet of returning. Is the Earth going to respond to
the lack of cyclic motion the same as the Sun?

"The magnetic poles wander around the vicinity of the geographic
poles all the time – the north magnetic pole currently resides
in the Canadian Arctic. However, at relatively regular intervals
throughout the 4.5 billion year history of the planet, the magnetic
poles have flipped completely. A few thousand years before a reversal,
the magnetic field gradually gets weaker; something which could cause
problems for inhabitants of the planet."

Now if we could only get it to oscillate at 50/60 Hz........;-)
