Thank you for the link. I learned about the periodic reversal of the magnetic poles (and the bands on the sea floor) over 30 years ago, when I was majoring in geology in college.

I don't keep up technically the way I used to when I worked professionally, but as far as I knew that theory of pole reversal has never been refuted.

I find it curious that no one in the pop science world has ever written extensively about it. It seems odd to me that something which has the potential to wreak all sorts of havoc on civiization is simply ignored; maybe it's because one can't blame anyone for the situation.

I wonder if during a magnetic pole transition there will be any increase in radiation at the surface. Is our atmosphere enough to protect us? I know lots of charged particles are deflected around Earth. Will we be ok but all our satellites hosed?
