You could try asking Jurg or maybe Christian Dullo. I don't reckon you'll need someone else though. Cheers Phil At 08:05 19/07/2004 -0400, you wrote: Hey Phil, I forgot what your response was on this. Would you be interested in co-convening this session in Beijing next August? If not, any suggestions for other possible European co-conveners? thanks, mike C9: Explaining the Climates of Historic Times: Detection and Attribution of Anthropogenic Influences (organized by ICCL) In the context of the detection and attribution of human influences on climate, understanding the magnitude of natural climate variability is essential. The instrumental record is relatively short and may be already contaminated by human influences. It is thus vital to gain as much information as possible about past climatic conditions, especially in the historical period of the past few millennia. This symposium invites presentations on proxy climatic reconstructions of this period on various timescales from interannual (e.g., from trees, historical records, ice cores, corals, sponges, and lake sediments, etc.) to centennial (e.g., from sediment cores and boreholes). Preference for oral presentation will be given both to the exploration of new archives and to the integration of a number of different records together, particularly from different proxies, and attempts to improve understanding of what factors might have caused the variations seen in the millennium on the decadal-to-century timescale. We also seek contributions that compare paleoclimate reconstructions with results from climate models forced with estimates of past forcing factors such as measures of solar output, the number and severity of climatically-important volcanic eruptions, land-use changes, and influences of late Holocene Earth-orbital changes.

Mann" X-Virus-checked: by University of Berne HI Mike, Thanks I have penciled the session in with your name for a start. I'll try to find a good Chinese and will wait to hear from Phil as to whether he is interested in co-convening. Keith Hi Keith, Thanks for getting in touch about this. I should be able to help do this. I'll let Phil reply separately, but I suspect that IPCC duties may complicate his involvement (I'm laying low this next round in IPCC--I'm not accepting any lead authorship responsibilities)... Would need to give some thought about an appropriate Chinese co-convener, although I know there are several prominent Chinese paleoclimatologists, so this shouldn't be difficult. In the even that Phil can't do this, I would probably want to have at least one European co-convener. In the meantime, here is a prospective session description below adapted from a session description Phi, Jean Jouzel, and I drafted for a very similar session we've been running at EGS (now EGU) over the past several years... mike Explaining the Climates of Historic Times: Detection and Attribution of anthropogenic influences In the context of the detection and attribution of human influences on climate it is vital to assess the magnitude of natural climate variability. The instrumental record is relatively short and may be already contaminated by human influences. It is thus vital to gain as much information as possible about past climates and in the above context the historical period of the past few millennia may be most relevant. This symposium seeks presentations on proxy climatic reconstructions of this period on various timescales from interannual (eg from trees, historical records, ice cores, corals, sponges, and lake sediments etc) to century ( eg from sediment cores). Preference will be given both to the exploration of new archives and to the integration of a number of different records together, particularly from different proxies, and attempts to improve understanding of what factors might have caused the variations seen in the millennium on the decadal-to-century timescale.

I wonder if either of both of you would be willing to run the symposium on " Explaining the Climates of Historic Times: Detection and Attribution of anthropogenic influences" - similar to the one you ran successfully at the last congress in Sapporo. If so, I would simply need a paragraph description (attached the one from Sapporo - MC16). Also, if you can suggest a Chinese co-chair that would be greatly appreciated. I attach the list of ICCL symposia that I have so far for your perusal. Further information on the meeting, and the PAGES meeting being held alongside, is here ([2]www.iamas.org and www.pages2005.org). I guess that given the combined IAMAS and PAGES potential participants, such a session might really be quite exciting and well attended. I look forward to hearing from you.
