#7: Death Of A Star: Gamma Ray Bursts, Black Holes
Huge-ass things that WILL end us if they happen, but they're so
rare that we don't really need to worry about them much. A
gamma-ray burst could still happen at any time, though, we MIGHT
see a black hole coming decades in advance.
#6: Intelligent Machines
Robots that are smarter than humans deciding they don't want us
around anymore and decide to stab the crap out of us and/or just
launch all our nukes at us.
#5: Supervolcanoes
Particularly, the one at Yellowstone. If it erupted, it would cover
the whole of the United States in ash and would flood all our
rivers. ANY supervolcano, however, would create problems for us,
such as global nuclear winter.
#4: Asteroids
The classic extinction scenario, involving a massive asteroid that
causes a global firestorm. Those who survive will inevitably
starve/freeze in the post-apocolyptic world that ensues.
#3: Nuclear War
Involves us and Russia blowing each other away. Iran, North Korea,
etc. are not the real threat here, it's still Russia that's the
real danger, though they'll probably end up blowing us up by
accident.
#2: Plague
Bird flu is mentioned here, but the real threat is a man-made virus
that ravages the population of Earth, killing billions.
#1: Climate Change
Florida, New York, London, Shanghai, Bangladesh, all gone,
according to Al Gore, Stephen Hawking, and a bunch of other guys.
It's because we're heating up the Earth with carbon dioxide, and if
we don't act now, it could be too late...

So how do you guys feel about this.
