Sounds good Martin. Keith, Tim - are you out there? Please help by ensuring we're doing the
right thing w Fig 6.13 and table 6.2

Hi Peck
Thanks for the provisional "go ahead" - we can (and so will) wait till Monday before
changing the master copy of the chapter here.
Regards
Martin

Hi Martin - this seems ok to me. I hope we hear from Tim and Keith - they are the key
folks on this one. If we don't hear from them, then we go with what you have done. Seems
quite reasonable to me, and I'm sorry we caused the TSU this extra work.
Thanks again, Peck

Dear Jonathan
Thanks for trying to sort this out quickly for us and for the information that the
Ammann et al paper is not available.
Susan and I have discussed your two options and have to say that we can not agree to
option 1 in the circumstances. Although the Jones and Mann (2004) paper shows the NCAR
simulation, the key point is that it cites it as "C. Ammann et al private communication
2003". So in effect option 1 would be bringing in material that was not peer reviewed
and not even separately documented. Anyone wanting to discredit your chapter would
highlight the fact that you appear to be depending on work done in 2003 that had still
not been peer-reviewed.
Option 2 is the only way to meet the standard that we have set all along of basing the
assessment very firmly on peer reviewed literature.
Kristen Averyt found that she could edit the EPS files that you had sent us earlier for
Fig 6.13 and take out the curves in question labelled AJS2006. The result is attached.
If you can confirm that this edited figure looks correct we are now proposing to drop
that into your chapter in place of the original one. We would also remove the [S4] row
in Table 6.2 referring to this study. We would also of course use the edited version of
the figure in the TS (Fig TS-26 in current draft).
If you can see any other implications of this approach to resolving the problem that we
need to be aware of please let me know. If the author team wants to provide a redrawn
figure that might be an improvement on the attached version we can still wait until
Monday morning for that.
Best regards
Martin

Hi Keith and Tim - need FAST help. Figure 6.13, and Table 6.2 cite Amman et al., for the
CSM curve. Since this paper doesn't yet exist in "in press" form (I checked w/ Bette,
who is a co-author), we have two choices. I think choice one below could be ok, but want
to have confirmation from Keith or Tim, and it it's not ok, (NOTE) Tim and Keith need to
get new Fig and Table to Melinda and Martin at the TSU by Monday.
Option 1: we can cite Jones, P.D., and M.E. Mann, 2004: Climate over past millennia.
Reviews of Geophysics, 42(2) - this paper (already in references - there is hope!) has
the CSM simulation in its Fig 8, but of course it's not the idea original reference
describing the simulation.
Option 2: we (Tim) creates new fig 6.13, and Table 6.2 without any reference to this
simulation.
PLEASE NOTE - if Keith and Tim (or Martin) feels we must go w/ option 2, Tim has to send
the new fig and table to TSU (Melinda Marguis and Martin) by Monday AM at the absolute
latest.

Thanks for your quick help, Peck
