“Reversals have been documented as far back as 330 million years. During that time more than 400 reversals have taken place, one roughly every 700,000 years on average. However, the time between reversals is not constant, varying from less than 100,000 years, to tens of millions of years. In recent geological times reversals have been occurring on average once every 200,000 years, but the last reversal occurred 780,000 years ago. At that time the magnetic field underwent a transition from a “reversed” state to its present “normal state”.”
780,000 years ago- Looks like we are about due. 2012?

If there is a connection between climate and the position of the magnetic pole, I don’t know what it is, or whether anyone has studied it. Since *everyone knows* that *only humans* can have an impact on climate, studying such a phenomenon would be a huge waste of grant money. ;’)
