Polar Reversal

What is it?
The basic theory here is that earth's poles will suddenly move out of alignment, disrupting the earth's magnetic field, thus causing cataclysmic weather and tectonic activity that will devastate our planet.

Oh no!
Proponents of this particular doomsday theory will tell you that it's been over 700,000 years since the last one, and that we're due for one. They will tell you that the earth's magnetic field has been declining for the past 2000 years. They will also tell you that the earth's magnetic field will drop to zero for a few days, causing violent weather, earthquakes and volcanoes.
