Climate change prophecy hangs its hat on computer climate models. The models have gigantic problems. According to Kevin Trenberth, once in charge of modeling at the National Center for Atmospheric research, [none of the] “models correspond even remotely to the current observed climate” [of the Earth]. The models can’t properly model the Earth’s climate, but we are supposed to believe that if carbon dioxide has a certain effect in the imaginary Earths of the many models it will have the same effect on the real earth.
The climate models are an exemplary representation of confirmation bias, the psychological tendency to suspend one’s critical facilities in favor of welcoming what one expects or desires. Climate scientists can manipulate numerous adjustable parameters in the models that can be changed to tune a model to give a “good” result.
