Reply #40: No, it won't

When conventional oil becomes too expensive, we'll just switch to the alternatives - tar sands and liquefied coal. There's no danger of them running out for a good few centuries, and they are much worse than oil, environmentally.

You're right that the US shutting of CO₂ will not solve the problem (although 6 billions tons pa would be a good start). But I'm not aware of the US making any giant leaps towards stopping CO₂ production: If anything, I think it's getting worse.

So that's one less thing to worry about, I guess. :silly:
