Ooo, the end of the world ...Forgive me if these are already mentioned:
#20) The Earth's core begins to cool and its internal dynamo ceases.
#19) The universe expires from the big crunch, big expansion, etc.
#18) The Earth is knocked out of orbit by unexplained forces and crashes into the sun or leaves the solar system.
#17) Teleportation is discovered and we accidentally teleport Earth to the outer fringes of the solar system.
#16) The sun explodes into a Nova incinerating the inner solar system.
#15) A Gamma Ray burst is fired from the poles of a nearby black hole and then ...
#14) The black hole consumes the entire solar system.
#13) My weather experiments deplete the ozone layer and the sun microwaves the planet.
#12) The milky way galaxy and the Andromeda galaxy collide.
#11) A 100 km asteroid / comet crashes into the planet.
#10) A near by planet's gravitational tidal pull rotates the planet's axis so the equator now runs across the poles.
#9) A super volcano blocks out the sun light and freezes the planet, "Nuclear Winter"
#

Nuclear warfare leads to nuclear winter. (A smiley appeared here. What gives? I didn't click on a smiley)
#7) God goes back on his promise and floods the planet again for 40 days and 40 nights.
#6) An EF 5 tornado or Catagory 5 hurricane slams into several nuclear power plants which then spew radioactive materials into the atmosphere.
#5) Y3K (Y2K was a hoax, you humans wont be so lucky next time. Mwuahahaha!)
#4) Aliens actually think Earth is worth invading.
#3) Humans begin to evolve into furries and furries prey on humans.
#2) Extreme Corona Mass Ejection weakens the Earth's magnetosphere and we become vulnerable to cosmic & solar radiation.
#1) Hackers break into the PureZC server and wipe out my account.
