Viv attached is the text you sent with some suggestions and comments (track changes must be on). I am also sending a small piece of text that could be expanded if needed (this to be inserted where you describe the treering input) - but at this stage I think you need to have a look at comments and consider the specifics of the lake and tree sampling (the latter if any). I thought it best to send these comments rather that plough on doing stuff you don't want. I think the "hook" needs to be the important opportunity to assess recent changes in lake and tree productivity and see if any evidence for response to climate , as well as searching for unprecedented evidence of climate change. I realise this is predominantly a lake project with a link to trees and models , but the links must be more than token . I can provide more background as to where we are with tree-ring work in Euro-Siberia if needed . I think the model stuff also needs specific justification . Is Simon going to contribute here? Don't get hung up on the "decline or changing sensitivity issue" in trees . This is NOT a great problem in Scandinavia, Ural/Yamal and is anyway a divergence in trend and quite subtle and evident in wood density mostly. We are also of the opinion that it could be partly a statistical processing artifact - we are exploring this now. If you plough through my comments and suggestions and then return the text with specific requests of what you wish to do I will then try to oblige thursday cheers Keith -- Professor Keith Briffa, Climatic Research Unit University of East Anglia Norwich, NR4 7TJ, U.K. Phone: +44-1603-593909 Fax: +44-1603-507784 [1]http://www.cru.uea.ac.uk/cru/people/briffa/ References 1. http://www.cru.uea.ac.uk/cru/people/briffa/
