Well, you have a few stumbling blocks:
a) While the mechanism for AGW is pretty obvious and indisputable, the actual predicted value of climate models has been lacking. That's just a fact. They are getting better, and they will get better, but it is fact that they are inaccurate today.
b) The private sector is already pricing risk due to climate change into models for various natural disasters. Right now this is just best guess based on the models, but as the models improve, so will the risk models based on them. So, the "cost" of climate is something the market is working towards deciding. Until that actual cost is well known and understood by all parties, it will be politically impossible for anyone with any degree of skepticism towards the government in general to agree to let government decide what that price should be.
c) Since, the price of doing nothing is not even agreed to yet, it follows that any mitigate response must be viewed with suspicion, because, you can't compare the cost of action with the unknown cost of damages. A tell tale sign that there is a perceptual agreement on this issue by everyone, purported denier, and believer, is that, most believers remain anti-nuclear power, and I've seen little evidence this administration has even considered increasing research into nuclear fusion.
d) If the climate is always changing, it doesn't matter in the minds of some, if man is changing it or not, when something else will change it just as well.
So, the actual dollars and cents reality is that the proponents of climate change reform are asking everyone to make some rather radical changes in their life, to let there be new winners and new losers, when it is not at all understood how much the winners will win and the losers will lose, if we choose to do nothing but let fossil fuels exhaust themselves or deal with doomsday when it happens. Sure, there's denialism, but by casting opponents of your point of view into that camp, all you've done is basically positioned yourself as someone who is advancing a political agenda with climate change as its mask, rather than fixing any problems of climate change itself.
