However, some pretty credible data cross correlated from the Black Sea, the Laschamp event in the Massif Central, and Greenland data, and shows a “rapid” 250 year complete pole shift, around 41,000 years ago, followed by a european super volcano around 39,500 years ago.
And let me throw this in….what about that really cool rise of Cro-Magnon man and epic cave paintings around 35,000 to 39,000? Indeed, magnetic pole shift appears to occurs with a lessening of overall magnetic field, which allows more cosmic radiation in to the home planet, which allows for more DNA damage and the occasionally successful mutation that works better. Saber toothed tigers probably kept the cancer rates in check pretty well.
We are in a period of very fast movement of the magnetic pole, and it appears the north pole has the itchy feet and the south pole is more stable.
What this means for the future imnot entirely sure but it certaintly is interesting to watch unfold. -Mort
