just following up some of those earlier posts regarding CO2 levels in the past. Also in the past as we emerged from the last ice age, the world went through a period of above average temperatures from about 800AD until 1300AD and then went into several centuries of lower than normal temperatures. Given that it is clear that warming and cooling cycles can extend over centuries, how can any projections made from data collected over a couple of decades be considered reliable. It is obvious that any projections made from data collected during an incomplete cycle has a high probability of being wrong, and if it was collected at the beginning of that cycle then the probability is at it's greatest. This has nothing to do with whether you believe AGW or not, this is pure simple logic, yet it is being totally ignored.
