   I have just read this lettter - and I think it is crap. 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)

     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,

     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.
