   I am attaching a few powerpoint slides - showing a current version of the Swedish series
   and the Finnish series . These will change very slightly (to reflect different
   long-timescale preservation) but the basic pattern of variability will not change. The
   first two Figures are annual values with bootstrapped 95% percent confidence limits. The
   final Figure is the overlay of the two with confidence bands removed for clarity. Note that
   the differences in the series often reflect low confidence in one or both series, The
   differences around the Medieval time and the "Little Ice Age" (!) are less in our modified
   data (still being worked on) but still maintain. I can produce numbers soon when we know
   were we are with publishing the revised curve(s). These data can be interpreted as evidence
   of summer temperature changes , on time scales up to multi-centennial , though millennial
   trends are not represented
   Cheers

     Dear Keith,
     Coming back to our brief chat in Utrecht on the tree-ring data from northern
     Scandinavia, I would greatly appreciate if you could send me a plot showing the two
     series.
     Thanks in advance!
     Best regards,
     Michael
