That's OK, the Earth's magnetic poles will soon be switching causing all
kinds of disasters. It's caused by the use of Iron by humans. Unless
we tax all past, present and future use of Iron...we will all
DIE...HORRIBLY!


You just rattled an old dormant brain cell last used in the early 70s, Tom.

We were studying the reversals of magnetic polarity in ice core samples.

The consensus at the time was that the magnetic pole itself didn't move,
it was, instead, a change of the axis of rotation.

A wobble - as in precession of a gyroscope.

That fell through to a new stable point.

Probably at something WAY over normal surface rotation velocity of the Earth
( eg: 1000 miles per hour).

Doncha just wonder...
