I don't want this to come off as trolling but AGW (Anthropomorphic Global Warming) has become politicized and the science is not "settled". The models and scientific theories proposed just have not held up.
Normally I would just not bring this up at all as a lot of this might be considered opinion but when all these opinions mean that people in Washington now want to tax me on it, then I just can't keep silent anymore. Believe what you will, donate to your charities, sponsor your wind turbines, but don't forcibly take my money to pay for your faulty science. I will give you this link and let you do your own research.
