Climate models are not intended to precisely predict global temperature on short time scales, so the fact that they cannot does not disprove their accuracy or utility.
Furthermore, global climate models are tools for a particular kind of research, not the basis for the theory of global warming--which predates electronic computers by about 40 years.
Evolutionary theory cannot reliably predict complex outcomes either. For example, despite the relative biological simplicity of a flu virus, scientists struggle to predict the strain(s) that will be most virulent each year. But I never see posts on HN holding this failure up as proof that evolution is not believable.
