I hope you'll be more optimistic about government outcomes, at least as far as opposition is concerned. I think I'd fall under your bucket of people that are "opposed to climate change", and I put that in quotes, because, it's not that I don't believe in climate change or anything like that. I just don't believe that the current "green" initiatives are the correct way to go about solving climate issues. I do however consider myself an environmentalist. I care more about the non C02 pollution that we are causing than simply trying to reduce C02 emissions.

I think you'd be hard pressed to find organic opposition to tackling environment issues that aren't related to the relatively abstract C02 pollution issues. I say organic because the corporations responsible for pollution will always find ways to manufacture consent that protects their own best interests. But, your stereotypical human-caused climate change denier is likely someone that hunts, fishes, or resides in a rural area, where environmental and conservationist concerns are taken very seriously, regardless of political affiliation. Your opposition is only going to come from people whose livelihood is affected by pollution controls. A broader swathe of people will always oppose addressing C02 related climate concerns because it affects literally everyone's bottom line in the form of rising cost of goods with energy prices going up, and it has abstract consequences, rather than concrete ones like your local streams being poisoned, or your well water going bad because the aquifer has been contaminated.
