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 Olga´s 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.

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.
