Someone asks me about Lieberman-Warner's Climate Security Act

Someone asked me what I thought about this bill before congress. "The first, most important thing is that any bill has to include real, mandatory cuts in global warming pollution." Here are some questions to think about:

Is there clear evidence that mankind is contributing to global warming? Hardly.
Even if there were evidence, is warming on net bad? Hardly.
Even if there were evidence of mankind's contribution and that warming is bad, we already have a lot of gasoline and other taxes. Do we know if those taxes are already too high? If so even if the arguments being made are true, we might have to actually cut the tax.

I have made these points before on this blog with some more references, but apparently it was necessary to make this point again.
