Richard Lidnzen At Fermilab

Richard Lindzen, who is arguably the most credentialed and respected sceptic of anthropogenic global warming, will be giving a colloquium here at Fermilab on Feb. 10 at 4 p.m. If you are in the area, you can come; the colloquium will be in Wilson Hall, 1 West. I hope to have an opportunity to ask a question; any suggestions about what I should ask?

I will briefly discuss why this is a peculiar issue, and illustrate this with various examples of how the issue is being exploited and portrayed. In particular, I will show how much of the science and phenomenology being presented is contradicted by both logic and data. Although there is a profound disconnect between the commonly cited IPCC conclusion and the various projections of catastrophe, it is nonetheless worthwhile to examine the basis for the IPCC attribution of recent warming to man because the arguments are profoundly at odds with normative scientific logic. Even so, the claimed result, itself, is consistent with low, and hence unworrisome, climate sensitivity. This talk will discuss how one can ascertain the sensitivity. Most approaches are faulty in that they use observed temperature behavior and assume its cause. We show how this trap can be avoided. There are several approaches, and they each lead to the conclusion that current models are substantially exaggerating sensitivity. However, because of the peculiar nature of this issue, it seems unlikely that either this or the evidence of data mishandling will serve to diminish the commitment of many individuals to the seriousness of the alleged problem.
