Is Global Warming a Hoax?

[MadMojoMonkey]

No, I don't disagree with this. If you insist that googling something to define it is insufficient, and mojo doesn't argue with you, I'll have to accept that you're not just typing words to argue with me.

And in this realm, we might as well question our very existence. If I can't be certain that 2+2 will = 5 tomorrow, how can I be certain that that I even exist? How can I be certain that drinking water will stop me from dehydrating? How can I be certain that breathing will provide the oxygen I need to survive? How can I be certain of anything at all?
