The real issue is that nobody really knows the size of the anthropogenic perturbation on the natural climate drift. Estimates are based on computer models and certain aspects of the physics are not well understood and therefore not easily incorporated into a computer model. This is particularly true with the modelling of cloud-radiation interactions. There is an enormous amount of science involved in the modelling-based investigations. I view it as a continued research effort that is not ready for use in setting public policy. You are correct in suggesting that there is some politics involved, particularly with the IPCC.
Does burning of fossil fuels impact our climate drift? Almost certainly. How much? That is the real question. Should we burn less fossil fuels? Probably. Will driving a Prius save the world? Probably not
Full disclosure: I wrote computer models for NASA and the National Weather Service.

But, that's just my opinion.
