I am not sure how to answer this question given all that is known about what affects our climate. However, for example, growing vegetation will on a net basis take CO2 out of the atmosphere, if ice melts and vegetation grows perhaps the interplay of those variable will have an offsetting affect. I have not seen a serious analysis of those kinds of factors in Hansen's work. Certainly he talks about the "‘albedo flip" involving ice and water, but what about the other variables, or has he concluded they don't matter?

While I also call into question the "9 year" statement, It seems somewhat irrelevant when taken into the context of the actual Issue...I dont really care if its nine years....or 50, its obviously going to be pretty bad at some point.

Given the age of the earth what period of time should be used to establish statistically meaningful determination of the globe warming. We are fixated on yearly measurements and look at the trends in that past 100 or so years. You guys are saying we need to accept that without question?
