Well, Keith we can adapt where we live, and how we decide to adapt our lifestyle to adapt to a climate change if we know that it is really happening. If it's is getting hotter and more arid we can ensure we have abundant water supply...etc, if it's getting colder then our adaptations will be different. The problem is that 5 years from now we'll be told by the same scientists that the earth is getting wetter, or dryer, or colder...or....? It is pretty hard to adapt to the unknown or the guesses.
