Robustness of Climate Models

Abstract

AbstractRobustness with respect to climate models is often considered by philosophers of climate science to be a crucial issue in determining whether and to what extent the projections of the Earth’s future climate that models yield should be trusted. Wendy Parker and Lisa Lloyd have introduced influential accounts of robustness for climate models with seemingly conflicting conclusions. I argue that Parker and Lloyd are characterizing distinct notions of robustness and providing complementary insights. Confidence, if warranted, need be by virtue of causally consistent climate models rather than by agreement upon projections by a diverse range of models.
