There is no evidence in politics. And economics is a social science. Don't expect the same kind of evidence as in physics or biology.
These are non sequiturs. There is evidence in climatology. And economics is a science, should we choose to treat it as such.
So waiting to be 100% sure that global warming is happening can mean it will be too late (more expensive), and is just as stupid as waiting to be 100% sure the comet will it the earth.
I think there's a better chance of a good outcome waiting on a demonstration of the supposed dire nature of global warming. Keep in mind that there's plenty of evidence indicating that the effects of global warming are long in coming, slow to occur, and moderate in effect. It is near trivial for a human civilization to adapt under those circumstances. I don't see the compelling reason to act that a significant, likely asteroid impact would have.
