10 ways the World Could End
Steven Petranek has some great points about where we should be putting defense money and how little Nasa has alloted to stop things that will (scientifically proven) lead to mass human extinction any day now:
One of my favorites is that in 1989, the 4581 Asclepius asteroid (300 meter diameter) crossed through Earth’s orbital field–the place we had been 6 hours earlier–which would have utterly wiped out the human race.

While I agree that a shift of the magnetic poles is scary to think about, the fossil record does not indicate any mass extinction coinciding with a shift in the poles. Not exactly sure why, but it lends some comfort.
