   Yes, Gavin,

   Ben was along with me on my project in Vietnam this past spring (I have been working there
   the past couple of years).  We have an important Vietnam conifer paper accepted in Climate
   Dynamics, with Sano as first author and it is described in the text, and I have a new 700+
   year ring width chronology from the same species from 12 degrees latitude that is just hot
   off the microscope, with amazingly robust signal strength.  We have strong evidence for
   several multi-decadal scale droughts that extended across SEA (they show up in my 2007
   Climate Dynamics paper on teak from northwestern Thailand, in Sano's paper from north
   Vietnam fokienia, and now my own record from south Vietnam fokienia).  We see that the time
   of Angkor collapse was smack in the middle of the worst extended drought of the past 700
   years.  I plan to submit a paper in the next 2 months on this, after we finish our Monsoon
   workshop in mid September.  I had a bit more of this in the first version but I seem to
   recall some comments to the effect that I was tooting the LDEO horn too much so I toned it
   down and included all the Poussart and isotope references that people seemed to want.  As I
   told Phil and Keith, I can change direction on this section any way people think
   appropriate.  Just let me know if you want me to include any of this, or anything else, and
   I can rewrite over this next weekend.  I also don't want to steal thunder from the paper I
   am about to submit, but I think I can find the correct balance.
   Thanks,
   Brendan

   Gavin,
      See next email re the final Appendix plot.
   The tropical dendro section is much larger. It was mainly
   written by Brendan Buckley who was likely with Ben on any
   recent coring trip to SE Asia. The section is optimistic.
   There are sentences on dating of trees without rings using isotopes.
   Cheers

     a couple of quick points - more later.

     - why does the CET line on figure A1 only go to 1950? Surely you have

     enough data to go to 1982 with no padding? I think that it is important

     to graphically show that even if you take IPCC90 at face value, it still

     shows that today is warmer. The graph will be looked at much more often

     than the text will be read.

     - I was talking to Ben Cook recently, and he was describing some tree

     species in Vietnam and Thailand that clearly had annual rings and that

     they were in the process of cross-validating the dating. In general, he

     was pretty optimistic about the prospects for tropical dendro. Thus in

     the response to reviewers and maybe the text, we should be quite open to

     this.
