I am sick to death of Mann stating his reconstruction represents the tropical area just because it contains a few (poorly temperature representative ) tropical series. He is just as capable of regressing these data again any other "target" series , such as the increasing trend of self-opinionated verbage he has produced over the last few years , and ... (better say no more) Keith At 11:16 AM 6/17/02 -0400, you wrote: Hi Tim, There was indeed a letter from Mike and Malcolm (the Prat; in Medieval times, that would have been his surname instead of Hughes) published in Science, with a reply from me. See below. In all honesty, I haven't even read what was published. I am tired of the whole thing. At every meeting I go to where Mike gives a talk, he always presents more on why his series is correct. Honestly, most people I talk to think that he is being way too defensive (as we all know too well). In any case, he is coming out with a new NH reconstruction. It will be interesting to see what it looks like. One problem is that he will be using the RegEM method, which provides no better diagnostics (e.g. betas) than his original method. So we will still not know where his estimates are coming from. Cheers, Ed Cook E.R. and J. Esper.

Hi Ed, Keith and I were talking last week and realised that neither of us had noticed the appearance of a letter in Science from Mike Mann, nor a response from you. Have we missed it? Hope all's well with you.
