None of the above Matt. The poles are gonna shift, they've done so since the birth of this planet, it's just a matter of time until next time it happens and at this point it's long overdue. And when the poles do shift, the earths magnetic field will weaken, leaving us more exposed to the sun's rays. And this is particularly bad in the case of a geomagnetic storm, which often occurs everytime the sun's poles shift, which is every 22 years, as apposed to the average of 780,000 years for the earth.
Last time we experienced a geomagnetic storm was in 1989, and it had some pretty dramatic effects:
On March 13, 1989 a severe geomagnetic storm caused the collapse of the Hydro-Québec power grid in a matter of seconds as equipment protection relays tripped in a cascading sequence of events. Six million people were left without power for nine hours, with significant economic loss. The storm even caused auroras as far south as Texas. The geomagnetic storm causing this event was itself the result of a coronal mass ejection, ejected from the Sun on March 9, 1989
In August 1989, another storm affected microchips, leading to a halt of all trading on Toronto's stock market.
With the earth's magnetic field weakened the effects will be much worse. How bad I have no idea, but I hope it wont be too bad. We're pretty darn reliant on electronics these days and seeing that a geomagnetic storm hitting the earth with a weakened protective magnetic field could fry each and everyone of our priced electronic gadgets then it would almost be like being sent back to the stone age.
