thanks Ricardo
the plot would be interesting - but I might not use it 'cause of space restrictions. Please DO send it anyway. Please tell me about how you and the rest of you see the interpretation of the various Fitzroya chronologies. Do you still think Inverse temperature in previous year? The fact that there are clear differences in the two temperature reconstructions (yours and the Lara et al) still make me think that the interpretation is difficult. I want to say that the potential for further long series is high but I feel I need to say something direct about the lack of clear common signal in the different Fitzroya series. I also want to say something about long-timescale change being not appparent in these data. In the London meeting , I showed a curve of the two reconstructions averaged. What do you think if I wished to put this in the paper and say the standardisation method(s) removed potential for seeing more than decadal-multidecadal changes?
Also , this David Keys keeps hassling me about 536 and the 540s in general. I see NO evidence for unusual behaviour in your data then , and he keeps trying to contrive one. What do you think. What are the main points about southern hemisphere tree-ring work , and south American stuff that I should make regarding future potential?
Cheers
Keith
