Regarding the pole shifting. There was recently a lift from the CIA of a book by Chan Thomas (Written some time in the earlier 1900s), where he analyzed the fall of past civilizations and linking it to a major cataclistic event. I'm not sure if this was also linked to a sudden pole-shift that would let loose hell on earth with fire followed by huge masses of water. Biblical to say the least :P

Also scary that they still didn't release 150 pages of the 200 page book :P
