Abstract: Both climate scientists and philosophers have been working hard to understand how the huge multidimensional global climate models can be tested and confirmed. The convergence of multiple climate models on a single outcome or result has provided a key feature in these discussions. Philosophers of science tend to think that such convergence, or “robustness,” is not confirmatory, because the models could converge and still all be wrong. Climate scientists, on the other hand, do tend to see the convergence of climate models on a result as confirmatory. I will offer a defense and generalization of the climate scientists’ position, while differentiating their style of robustness from others considered by philosophers.
