recently back from Liverpool - had to cancel a trip to see Ed in the States over
thanksgiving. Dad ill again!
I did look at the comments and am a little disappointed at Jurg's. OK he wants more on
Europe and the last few centuries but beside putting in the caveats he wants and confirming
the space restriction that dictated the regional foci we chose (and of course adding in a
few references) I don't see we should do a rework to stress a Late Maunder Minimum effect .
This brings up the need to reconsider the solar effect on climate - have you seen the
latest Bond et al. paper.
([1]www.sciencemag.org) I am a bit surprised that the relationship looks so good (between
Be and Ice Rafting over the last 12000 years) . It is very convincing at first read through
- but I still do not believe it. I need to re-read the details of averaging, smoothing etc.
but other than suggest that they fiddled the data I have to admit surprise at the
relationships they show. The lack of comparison over the last 3000 years is frustrating . I
have also just received a paper by Curt stager (with Beer and Meeker) that shows (weaker)
evidence of a link with solar variability and African moisture changes in the last 1000
years ). All of a sudden the sun is back with a bang!
As for our piece, the missing southern Hemisphere stuff is a hole I feel we have to fill. I
can do the tree-ring side if someone else does the rest. I feel the new speleothem record
needs to go in my Figure and I can do the Lutterbacher wording changes - but I am still
confused on the ice stuff. Should we change that Figure in any other way? What do you think
about the discussion of it? We need to rework the text again generally at a finer level but
we can all have a go and you decide on the details . Other than that I have nothing else to
say - because we know this is a space limited project and you will not please everyone .

Hi Keef:
Did you have a chance to look over the comments on the synthesis chapter? Any thoughts
before I proceed? We need to get revisions done by the end of december.

I asked for this chapter and comments but you have not sent them yet (there was no
attachment on your message) - have you seen the latest speleothem paper in Science
(McDermott et al) 294,1328-1331) . Very interesting - not much overall Holocene cooling;
but good dating of events such as 8.2 . very cautious interpretation of oxygen isotope
values - how does it compare with Stein Eric's record - not that much.

I attach reviews of our chapter. In general, we got good marks, but there is concern
(that I think we all shared, initially) that we could do a better job in representing
the record of the SH, and (b) a lot of recent literature on the NAO & Maunder Minimum
has been overlooked. I guess a third point, re Chinese records, is also made.
How to proceed? To avoid a chaotic process, I suggest that we all just read over these
comments & consider the best way to go forward. Email your thoughts to everyone.
If you can see very specific sections that you can easily respond to, please identify
that part to me and I will not then try to take care of it myself. Otherwise, I will go
through the paper and try to fix the minor points, then I will contact you with an
updated version, with specfic "assignments" for each of us to be responsible for
fixing....OK? we need to have a "final" draft to the PAGES office by 1/15 (2002!!!) at
the latest.
Let's not let this drag on again, or it will just keep getting more & more difficult to
keep it current...
