Many thanks, I'll read up on it.

I'm not looking for an "absolute certainty" I'm looking for statistical significance of accuracy. It's fair to say that these models that we are referring to are either accurate or they are inaccurate.

I'm sure nobody would want to base public policy on inaccurate or skewed data. That is my quest. Just as the famous "hockey stick" graph could not hold up to scrutiny, I would like to examine these claims that computer models are showing. Follow the questions...right Fred ;)
