From: Keith Briffa To: jto@u.arizona.edu,David Rind , joos@climate.unibe.ch,Eystein Jansen Subject: near final 6.3.2.1 Date: Thu Jan 13 19:03:36 2005 Guys here is the latest draft of 6.3.2.1 (only waiting on slight edits on ocean bit from Eystein and ENDNOTE reffs to be sorted. Have agreed with Peck and Eystein to do a Medieval Warm Box tomorrow and insert a sentence or two on lack of info for SH .Figures of course need work - particularly sorting out how to represent uncertainty around all reconstructions in Fig 1 and represent totality ion Fig 2d. Also some forcing data still missing - may have to wait til after ZOD (will also need to put in other borehole curve(s) but data not to hand). Having virus troubles with by email (and our system randomly blocking some files) - sorry so don't know whether David has seen this at all (re his comments on Figures - which are now embedded as GIFs and attached separately as 2 files in case go wrong again. As I type just got Stefan's message and comments and Goose paper- will look at tonight and incorporate tomorrow. David - I know it is received wisdom that volcanos only force climate for 1 to 2 years - but in our SOAP transient models this is not the case where several large eruptions occur (co- incidentally often in sunspot minima periods - see the actual magnitude of radiative forcing in Figure 2 (and these effects are directly transmitted as continually propagating coolings in ocean in HADCM3 and ECHO-G for up to decades i believe. Anyway - I am happy with your conclusions and agree that these are not "negative". I would rather just pick a cool period and not label it as MM (or late MM ) as this is a solar definition as such should be defined according to solar proxy data (and hence choice of shorter period seems unsupported). If you just say a date range without the label , I think it avoids the issue. Sorry for garbled writing but rushing - I like your bit (in case this did not come across) thanks all for now 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/
