Hello all,
I apologize for the difficulties we've been having with the email list server. This
email, which should have gone out to you all yesterday, was apparently never processed
by the email list server. I'm sending this manually, so that you may have it as soon as
possible. -- Roy

Dear Colleagues
Please find attached a compilation of the comments received from governments and NGOs on
the final draft SPM. We may get some further late comments but these are a substantial
set (nearly 1000) and probably raise all the major issues. In order to make it easier
for you to find your way around them, we are providing 5 separate files corresponding
to: General + introduction section; Drivers section; Observations section (inlcuding
paleoclimate); Attribution section; and Projections section.
Overall we are very happy with the way in which the SPM is being received. Although
there are many minor issues where the comments identify misunderstandings that need to
be cleared up, or suggest better ways of expressing things, there are only a few major
issues. These are consistent with some of the comments on the previous draft and so are
not unexpected.
As in the work on our previous draft SPM, it's important that we jointly develop
responses. Our preparation should work towards a successful process. Many constructive
and helpful comments have been made in the attached but there are also constraints of
several types. Some of these are practical, procedural, or based upon precedents, and
we will need to discuss those. Please note that time will be very limited during the
formal IPCC sessions in Paris and will also constrain what is practical. A much longer
SPM is simply not an option, and we already have more figures than were in the TAR
SPM. Finally, it is important to recognize that at previous IPCC approval processes,
some written comments by governments were superceded by quite different stated concerns
in the formal session, so the written comments cannot be assumed to be absolute at this
As we have mentioned earlier we will use our meeting on Jan 27 and Jan 28 to finalize
our jointly proposed revisions to the SPM in response to these comments. The TSU is
currently preparing a revision in which all the more mechanical and obvious revisions
are made. Early in the new year we will be contacting subgroups among you on specific
science points and trying to ensure that we have discussed all the key SPM revisions
carefully by email or conference call before arriving in Paris. We will also need to
prepare some presentations to the delegates in Paris to assist the process.
During Jan 29 to Feb 1 we are planning two types of science presentation by CLAs or LAs.
The first type will be given during the 2-hour lunch breaks or in the mornings before
the start of the plenary session. These will be open to any delegates who are
interested, will be informal in style (no translation) and should be from 15 to 30
minutes long. The aim in these presentations will be to explain some of the underlying
science, show typical data or results from the chapters where appropriate, and allow
delegates to ask questions. These have been very helpful in the past as they allow
delegates to interact with the authors in a seminar type of environment. They help to
clear up misunderstandings and can be used to explain why some things being asked for by
policymakers can not be provided. E.g in this type of presentation we would hope to
explain why observed changes are often expressed probabilistically (which confuses some
people) and how the sea level rise projections are derived. We should be able to
allocate about 3 or 4 hours in total to these presentations and will cover a range of
science topics suggested by the comments so far. In the attached compilation of comments
the ones that we think can be assisted through science presentations are highlighted in
a cyan color.
The second type of presentation will be given as part of the formal plenary session and
be used to introduce the key issues as we start each section of the SPM. These
presentations should be 5 to 10 minutes long and summarize more specifically what is in
the SPM and where it has come from in the chapters. We will only allow a very limited
number of questions for these presentations and their main purpose is to orient the
delegates to the material they are being asked to approve and remind them that it has to
be based on the chapters. E.g this type of presentation could help clarify why we do not
mix attribution statements with observation statements.
To summarize: We will be contacting a few of you separately today or tomorrow about
preparing the longer type of science presentations for Paris, then after Jan 1st we will
be contacting subgroups regarding our options for revisions to the SPM.
If you have any very specific suggestions for how to deal with particular comments or
groups of comments please let us know. In the meantime enjoy the holiday season and we
will be in touch again shortly.
Susan, Dahe, and Martin
