Doomsday:

The Bulletin of the Atomic Scientists, keepers of the Doomsday Clock, have some theories they'd like to share on what scenarios are most likely to lead to the end of the world.

It's always been a harum-scarum project, the Doomsday Clock. Take what they say with that grain of salt -- they're serious thinkers, but they want you to be scared so you'll not argue with their policy ideas. That said, you might want to take a few moments to see what they've got to say. When they say you shouldn't bother worrying about something, you can really stop worrying about it.
