 Okay, the other impact raised by Hansen et al., in fact, part of their proof, is a pattern of towering waves descending on the Caribbean from these storms, and it's partly dependent on the length of the ocean, or fetch, as the mariners say. Have you heard anything about larger-than-normal waves in the age of climate change? It's tough. We don't have very good wave observations going back very far, but there is some thought that, yes, wave heights are increasing in some portions of some of the oceans.
