   Hi,

   Concerning the glacier box:

   I suggest we aim to work on this issue before the Beijing meeting. I can co-ordinate an
   e-mail discussion and bring in, when needed those who helped us with the box. The first
   pass, I suggest would be to look at  the comments we have received and Olgas suggestions,
   then draft a revised text and response to the comments for discussion.

   OK?

   Concerning the last two millennia.

   I agree that the issue of multidecadal and longer time scale variability needs more
   emphasis, and that this issue is a bit lost in perhaps too much detail in the ZOD. I am
   sure, now that we are done with our EU bid, things will progress on the European side.

   Cheers,

   Eystein

     Hi Olga - thanks for the more detailed comments. What do you think of the Oerlemans
     paper. Seemed quite interesting too me, but I find it hard to assess.

     We have two options for discussing the box. One would be to discuss in China at LA2, but
     it might make more sense to discuss before then, and perhaps with the others who helped.
     Could we do this by email - perhaps send the final text to everyone and then get
     ideas/comments. Then try to come up with a plan that can be finalized in Beijing?

     What do you think Eystein?

     Keith and Valerie - I know we're waiting for you to finish your proposal and send all
     your requested input, but would you please add this email query to your list of things
     to do as soon as you can.

     Thanks all,  Peck

     Hello everybody,
     1.ZOD comments
     There are two papers appeared recently that we certainly have to discuss in our chapter
     both dealing with the LOW FREQUENCY VARIATIONS of the last two millennia:
     Oerlemans, J. (2005). "Extracting a Climate Signal from 169 Glacier Records." Science:
     www.sciencexpress.org / 03 March 2005 / Page 3/ 10.1126/science.1107046.
     Moberg, A., Sonechkin, D., Holmgren, K., Datsenko, N., Karlen, W. (2005). "Highly
     variable Northern Hemisphere tempertures reconstructed from low-and high-resolution
     data." Nature 433(10Feb): 613-617.
     My main concern about the last 2ka and the MWP box is the lack of this (low-frequency)
     topic. I like the whole text in general, but I feel like there are too many technical
     details on "spagetti". I agree that the global temperature reconstructions based on
     annually resolved records are probably the most important achievement and the main
     stream, but we are loosing sometimes this way some very important evidences and issues.
     I do not mean just glaciers, but, say, lake level variations, marine sediments, Southern
     hemisphere data, Antarctica versus N Hemisphere and some other important issues.
     2. I would very much appreciate if we discuss futher the glacier box. It is far from
     being ready and I need a feedback from you.
     3. Links ch 4
     I sent a rough text to Georg Kaser who is in charge for glaciers in ch 4, but had no
     answer so far. He has been in the field, so might be just too busy to answer. I will
     contact you again as soon as we agree about the text on "glaciers in LIA and beyond" to
     discuss the problems of probable contradictions.
     Regards,
     olga
