   IN  CONFIDENCE
   Tim do you fancy this? I have 3 others at present? Should I do it anyway given the EBM
   component!!!!

     Dear Dr. Briffa:
     Would you be willing and available to review "Are Reconstructed Pre-Instrumental
     Hemispheric Temperatures Consistent
     With Hemispheric Instrumental Temperatures?" by Natalia Andronova, Michael Schlesinger,
     Michael Mann, submitted for possible publication in the Geophysical Research Letters.
     The manuscript's abstract is:
         Reconstructions of Northern Hemisphere near-surface temperatures from
     climate 'proxy' data such as tree rings, ice cores, and corals, suggest that late
     20th century Northern Hemisphere mean warmth is anomalous in the context
     of the past centuries and likely at least the past two millennia.  Though
     substantial uncertainties in the paleoclimate reconstructions exist, these
     findings add to the evidence for a discernible human influence on climate.
     Here we use our simple climate model with six radiative-forcing
     reconstructions and climate sensitivity determined from instrumental
     temperatures over 1861 to 1997 to simulate the forced pre-instrumental
     hemispheric-average temperatures from 1500 to 1860. The model-simulated
     pre-instrumental temperatures indicate that the proxy temperature
     reconstructions are consistent with the instrumental temperatures in the
     Northern Hemisphere, but are too warm in the Southern Hemisphere.
     Lowering the pre-instrumental temperatures in the Southern Hemisphere by
     about 0.2oC would thus further strengthen the case for human-induced
     warming during the 20th century.
