Looking at the papers I have available , I realise that in the time available ( a week!) I can not do justice to the need to understand critically the issues of interpretation that bare on whether the question of agreement or disagreement with the various proxy reconstructions. At this stage I just need quick input for the zero order draft (now late) with references and authoritative account of the consensus between you guys of the so-called "optimal" interpretation of Mann of these data in the context of other (up to date) interpretations and problems therein . Please get back to me as soon as .. would be really grateful --- and yes should have asked much earlier 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/
