It’s suffering from permanent paradigm paralysis, and it’s time to put it down:

Paradigm paralysis is the inability or refusal to see beyond the current models of thinking. The vast amount of scientific and political capital invested in the IPCC has become self-reinforcing, so it is not clear how move past this paralysis as long as the IPCC remains in existence. The wickedness of the climate change problem makes if difficult to identify points of irrefutable failure in either the science or the policies, although the IPCC’s insistence that the pause is irrelevant and temporary could provide just such a refutation if the pause continues. In any event, there is a growing realization of that neither the science or policy efforts are making much progress, and particularly in view of the failure climate models to predict the stagnation in warming, and that perhaps it is time to step back and see if we can do a better job of understanding and predicting climate variability and change and reducing societal and ecosystem vulnerabilities.
