Colloquium: Hybrid models, climate models and inference to the best explanation

I examine the warrants we have in light of the successes of a kind of models I call ‘hybrid models’, a kind that includes among its members climate models. I argue that these warrants’ strengths depend on inferential virtues that are not just explanatory virtues, contrary to what would be the case if inference to the best explanation (IBE) provided the warrants. I also argue that the warrants in question, unlike those IBE provides, guide inferences solely to model implications the accuracy of which is unclear. My conclusion provides criteria of adequacy for epistemologies of climate and other hybrid models.
