   Hey Phil,
   thanks--nice coincidence in timing. So the 1990 graphic will be discussed in this review
   paper, right? Perfect, I'll let Gavin know.
   Will look into the AGU fellowship situation ASAP.
   I don't read E&E, gives me indigestion--I don't even consider it peer-reviewed science, and
   in my view we should treat it that way. i.e., don't cite, and if journalists ask us about a
   paper, simply explain its not peer-reviewed science, and Sonja B-C, the editor, has even
   admitted to an anti-Kyoto agenda!
   I do hope that Wei-Chyung pursues legal action here.
   So didn't see this recent paper, nor have I heard about the IJC paper, Christy and Spencer
   continue to lose more and more scientific credibility with each awful paper they publish.
   Gavin is planning to do something on the Loehle paper on RealClimate, I'm staying away from
   it. I have a revised set of hemispheric reconstructions which I'll send you soon, its
   basically what I showed at AGU last year. Submitted to PNAS--more soon on that,
   mike

      Mike,
         Some text came last night from Caspar. Keith/Tim writing their parts still.
      I have text from Francis, so almost all here now. Still need to find some time
      - maybe the Christmas/New Year break here - to put it all together. There
      is so much else going on here at the moment with other papers, it will
      be hard to find some time. I wish they had all responded much sooner!
          As for AGU - just getting one of their Fellowships would be fine.
       I take it you've seen the attached in E&E.  I've not heard any more from
      Wei-Chyung in the past couple of months.  I'm working on a paper
      on urbanization. I can show China is hardly affected. Will send for you
      to look over when I have it in a form that is sendable. Would appreciate
      your thoughts on how I will have said things.
       Have another awful pdf of a paper accepted in IJC !! It ws rejected
      by all three reviewers for GRL!  It is by Douglass, Christy , Singer et al
      - thus you'll know what it is on.
        Have booked flights for Tahiti in April, just need to do the hotel now.
      Cheers
      Phil
      Cheers

     Hi Phil,
     I hope things are going well these days, and that the recent round of attacks have died
     down. seems like some time since I've heard from you.
     Please see below: Gavin was wondering if there is any update in status on this?
     By the way, still looking into nominating you for an AGU award, I've been told that the
     Ewing medal wouldn't be the right one. Let me know if you have any particular options
     you'd like me to investigate...
     thanks,
     mike

this reminds me. What's the status of Phil Jones and Caspar's
investigation of the IPCC90 curve? Phil wanted us to hold off for some
reason, but is that done with?

That's a great story that needs to be told.
