Sure, but a pretty high percentage of the US believes anthropogenic climate change is not real. They think it's either a misinterpretation, or an explicit hoax.

Sure, but a pretty high percentage of the US believes anthropogenic climate change is not real. They think it's either a misinterpretation, or an explicit hoax. Most of the Republican party denies climate change, or at least denies that human activity is playing a significant role in it. We can't have reasonable debates on cost-effectiveness when so many people deny the fact that there is even a problem at all.
