I also don't think it's unreasonable to question if the net magnitude and effects of human induced climate change have been (or even can be at this point) modeled well enough to make accurate predictions. It's certainly not a consensus as far as I'm concerned although I think most reasonable people agree it's likely we are altering the climate.
