based on scientific research, much like communism and scientific management and phrenology and racism. meanwhile climate models are not capable of predicting the past given current conditions, produce wildly incompatible results, and operate on a model of the earth that is pathetically simplistic, ignoring cloud coverage (which has 3-20x the magnitude of effects of carbon) solar variability and wind patterns. the world might end as we know it for it is clear that crucial features of the earth are changing at a rapid pace, especially oceanic currents, but it will happen in a way that completely surprised most people, if not climate scientists that are aware of the limits of their models.
