I don't see any conspiracy here. Humankind is f*cking up the earth, and if the world ends in 2012 as is predicted, I would say it's our own demise! Tornadoes in unusual places? Sounds like global warming (climate change) to me...
But! That's just me being cynical... Perhaps.
Anyway, I remember hearing from the Mormon Church,, at least when my mother was part of it, that the world would end in 2000, during the new millennium, Y2K. It didn't, obviously, and even though I had lost all faith in blind faith, it was still a mind catcher to me that perhaps things will just keep on going.
I don't really know where I'm going with this, but it's all my own thoughts.
