Against “Possibilist” Interpretations of Climate Models

Abstract

Climate scientists frequently employ heavily idealized models. How should these models be interpreted? Some philosophers have advanced a possibilist interpretation: climate models stand in for possible scenarios that could occur, but do not provide information about how probable those scenarios are. The present paper argues that possibilism is (a) undermotivated, (b) incompatible with successful practices in the science, and (c) unable to correct for known biases. The upshot is that the models should be interpreted probabilistically in at least some cases.
