The Nova show seemed to point to it just being a cycle thing. They were doing ice cores that were really old and that pointed to a set of warm-cool cycles. It won't happen in our lifetimes but what are people going to do in the future when the inland seas start again? All the warming is melting the ice caps and it will be flowing back to where seas were before. Especially around the large lakes and coasts in the different parts of the World.
The San Fernando Lake?!
The Ohio Sea?!
