   I think your points are fine - the whole issue of estimating model sensitivity implicit in
   your a) and b) could be more explicit perhaps

     Dear IPCC WG1 Chapter 6 modeling-related authors - Pls see Martin's note below and send
     me your list of the 2 to 3 most important issues to resolve during this overlap cluster
     session in Beijing. Try to keep your list short; perhaps several small issues can be
     dealt with under a bigger issue.
     Ideas that come to my mind are (please help me frame these better if you agree that they
     are issues):
     a) EMICS and GCMs - how to present in a balanced and consistent manner?
     b) model evaluation and implications for models used in Chapter 10 (e.g., does the IPCC
     put too much weight on models that appear to evaluate less well?)
     c) are discussions of what is known and not known about hypothesized climate forcing
     (e.g., solar) consistent across chapters?
     What else?
     It appears that I need to send Martin feedback soon, so please send your input to me
     asap. CC to the others unless there is a reason not to, but everything should go to
     Eystein too.
     thanks, Peck

     Dear Tom and Peck
     Please find attached our current program for the second Lead Author meeting on May 10 -
     12.  We will shortly be sending out some more details on the plans for the meeting and
     in particular would like to clarify what needs to be done in the Overlap Cluster
     meetings shown in the program on Wednesday 11th.
     This is to ask if you would be prepared to jointly co-chair the session on Overlap
     Cluster D dealing with "Consistency in coverage of modelling on various time scales" and
     which will involve discussion among chapters 6, 8, 10 and possibly also 4, 7, 9 and 11.
     The attached program lists, on the last page, overlap / consistency areas that have been
     mentioned in the ZOD.
     We would really be most grateful for your assistance in this, and if you agree, we would
     like to ask that you each to specify what in your view would be the 2 or 3 most
     important issues to resolve during the overlap cluster session. We will then use your
     input to draw up a specific agenda and circulate agendas for all overlap clusters to all
     CLAs prior to the meeting. We hope in this way that we can reach a shared understanding
     of the most important overlap and consistency issues and the corresponding key decisions
     that will have to be made in Beijing.
     I would be grateful if you could let me know whether you are able to help us with this
     by Wednesday 20th.
     Regards
     Martin
