This week, all of the world's fancy folks and their limousines (which hopefully run on biodiesel) are in Copenhagen. There they plan to save the world from a temperature bump of a couple degrees Fahrenheit by having a big summit.

But what if it's all for naught? No, we're not talking about hacked emails, or anything like that. It's just when we start hearing about climate projections for 2100, we get really skeptical about humanity's chances of lasting long enough to be swallowed by the balmy ocean.

So, we've rounded up the usual suspects of planetary catastrophe, and would like to know which one you think will win the race to make all of what we love and cherish go the sad way of the dodo bird.
What Will Be First To End Our World As We Know It?
Global Warming -- or just call it climate change.102 (15.5%)
Rise of the machines -- make sure to treat your robot right.71 (10.8%)
Deadly space invader -- either alien or asteroid.110 (16.7%)
Nuclear holocaust -- two suns in the sunset.251 (38.1%)
End Times -- Rapture is so much more than just a novelty song from Blondie.124 (18.8%)


Global Warming
True, the face of global warming is serial exaggerator and award collector Al Gore. But most of the scientists who know about these types of things also seem to be pretty worried about carbon's effect on our overall climate and our lifestyles.

Why the threat may be overblown: Headlines like "Decade of 2000s Was Warmest Ever, Say Scientists" (emphasis ours) worry you when you remember some other areas where scientists fell prey to overestimation.

Killer Robots
It stands to reason that the wonderful age of "robots doing all the things we don't want to do" will be followed by the terrible age of "too-smart-for-our-own-good robots get their revenge for all the years they were made to fight wars and handle excrement."

Why the threat may be overblown: Giant "off" button. Come on, if we're able to invent robots that are conscious, surely we'd be smart enough to also give them a giant "off" switch.

Havoc From Space
It's been almost 66 million years since an asteroid caused mass extinction on Earth, so we're getting past due for another. As for aliens, not uncovering any evidence of extraterrestrials just means we'll be totally screwed when the sneaky bastards do show up.

Why the threat may be overblown: Bruce Willis would never let any of this happen on his watch.

Nuclear Holocaust
Isn't it weird that a lot of the people who are screaming about global warming used to focus their yelling time on nuclear proliferation? It's not like the threat of cascading mushroom clouds is getting any less likely.

Why the threat may be overblown: On the other hand, if entities like North Korea or Al Qaeda do finally acquire what others invented over 60 years ago, they are probably going to be extra motivated to stick around so they can show off by testing their new toys over and over again.







The End Times
It's true the end times are going to be nothing but a giant ball of fun for Christians in good standing. But the rest of Earth's inhabitants will suffer greatly at the hands of both a vengeful God and Satan, the beast.

Why the threat may be overblown: Pictures like this make us think the seers of the apocalypse haven't spent a lot of time going over the data.
