Hi Olga - it is not too late to ask these good questions. Glaciers can, of course, be
affected by both temp and precip changes, so the question is really for Valerie (land) and
Eystein (ocean) - are the land and ocean data from the tropics strong enough to outweigh
what the glaciers are saying about tropical temps earlier in the Holocene? Lonnie's Figure
8 (see attached) presents Hauscaran and Kilimanjaro data that suggest early to mid warmth
in tropical South America and Africa that is (if the O-isotopes are temp) greater than
today. Personally, I'm quite unsure that these are reliable temperature records, BUT if we
want to make that case, we have to be convincing. What do terrestrial and ocean temp data
say?

Thanks Olga for sending the proposed revised text - I think Eystein is putting finishing
touches on the next draft for LA etc. review.

Best, Peck



Hello everybody,



I attach here a version of glacier box and suggestions (in red) how to include there the
reference to the new Thompson et al., 2006 paper.



In this relation - I am getting more and more concern about our statement that the Early
Holocene was cool in the tropics - this paper shows that it was, actually, warm - ice
core evidences+glaciers were smaller than now in the tropical Andes. The glaciers in the
Southern Hemisphere (Porter, 2000, review paper) were also smaller than at least in the
Neoglacial. We do not cite Porter's paper for the reason that we actually do not
know how to explain this - orbital reason does not work for the SH, but if we do cite it
(which is fair) we have to say that during the Early to Mid Holocene glaciers were
smaller than later in both Northen, and Southern Hemisphere, including the tropics,
which would contradict to our statement in the Holocene chapter and the bullet. It is
probably too late to rise these questions, but still just to draw your attention.



I am going to Kamchatka tomorrow, but will be avaliable by e-mail from time to time.



All the best,

olga

Hi Olga - I agree, and hope that you and �yvind make sure you include it in the next
round of edits, which will begin very soon. We have all of the new text and Eystein is
assembling for authors to check. This same new draft will be the one that Eystein and I
work on to achieve more consistency and the proper length. Although we've cut some text
already, some received has grown too. So... think about a way to include the reference
to Lonnie's work without lengthening if you can.

OK? Many thanks, Peck

Hi Peck,


Lonnie's paper is a very good one and suitable for the glacier box. If it is still
possible I would add this reference.

Hi Chap 6 LA's - here is another batch of papers from the TSU to be considered using the
guidelines provided below - we don't want to add citations just to make our ref list
more complete.

Thanks, Peck and Eystein

Subject: Additional In-Press Papers

Dear CLAs
Please find attached additional paper(s) that are relevant to your chapter and have been
submitted in response to our most recent guidelines for consideration of papers
published in 2006 following the expert and government review. A separate spreadsheet
file is attached listing: the submitter, file name of the paper, its acceptance date,
and the chapter and section which the submitter feels is relevant.
As discussed in Bergen, please note the following:
* inclusion of additional papers in the final draft should not open up any substantive
issues that were not in the second draft and so not previously reviewed;
* additional papers should only be used where in the view of the LAs doing so provides a
more balanced coverage of scientific views;
* we anticipate that a quick reading of the abstract of each paper will enable a
decision consistent with this and we would not encourage any lengthy consideration by
the LA team.
One additional point to keep in mind is that this most recent adjustment of our
publication deadlines should not be perceived by others as a device for allowing the LAs
to reference more of their own papers. We trust that you and your team will be both
objective and vigilant when deciding to include or reject papers in this respect.
Best regards,
WG1 TSU
