Dear all,

we (Keith and I) agree that it isn't appropriate to cite only Jones
and Mann (2004) as a reference for the NCAR CSM curves in figure 6.13.

Another alternative to deleting the curves, however, would be to
reference Mann, Rutherford, Wahl and Ammann (2005), which should
already be in the reference list. This might be an appropriate
reference because it includes Ammann as a co-author and provides a
more information about the simulation than Jones and Mann
(2004). However it still relies upon the submitted Ammann et al.
paper as the main reference -- so maybe still not good enough? I've
attached a PDF of Mann et al. (2005) for you to consider.

From earlier discussions (and perhaps also in relation to chapters
using new model runs of future climate), I thought that a new
unpublished run with an existing published model under published
forcing might be allowed (in the same way that updated 2005 or 2006
instrumental temperatures could be included, even if not published,
providing they were compiled following the procedures described in an
earlier paper). For instance, the EMIC runs we included as an extra
panel probably fall in this category. Maybe the CSM run falls in
this category too? Have other runs with this model been
published? And the forcing used in this run was presented in Goosse
et al. (2005; GRL 32, L06710, again it includes Ammann as a
co-author) as well as in Jones and Mann (2004). So, maybe CSM can be
included under this reasoning?

I don't want to sound as if we are arguing strenuously to keep the
CSM curves in the figure -- if the preferred decision is to drop it,
then so be it. If so, then the modified figure looks ok.
