New Evidence for Pole Shifts Causing Extinctions
A recent study describes evidence found in a tree from New Zealand that lived 42,000 years ago during the magnetic shift known as the Laschamp Event. Though the study ignores more recent pole shifts including the one that ended the Pleistocene Age and the North American ice cap around 12-13,000 years ago - the New Zealand study does show how dangerous even a temporary loss of Earth's magnetic shield can be. It led to the extinction of Neanderthal Man. Such extinctions are only partially due to increased radiation levels - as magnetic pole shifts also coincide with cataclysmic geophysical pole shifts - in which the entire crust of the planet moves over the core in one solid piece. Most evidence suggests we are already in the magnetic portion of the next pole shift, and that the next pole shift catastrophe - the part that causes megaquakes and tsunamis on a biblical scale - is due to bring an end to our current civilization within the first half of the 21st century.
Update* As Ben Davidson wrote a few hours after I posted this: "In case you spent yesterday under a rock, another top journal confirmed the entire purpose of this [youtube] channel... only this time the world took notice. Magnetic excursions of earth's field are extinction events... the next one is underway now."
