    Tom,
      There was a paper on Greenland temperatures in GRL by Hanna and Cappeln
    GRL 30, 1132 DOI: doi:10.1029/2002GL015797.  It only looked at temperatures since
    the 1950s. Since then there has been some cooling particularly in the SW part.
    Not read the paper in CC referred to - will download. Recognize the name Jason Box.
    I think there is a poor paper with his name on - yes, found it, IJC (2002) Vol 22,
   1829-1847.
    The correlations of -0.84 to -0.93 are ridiculous. Box has these at more realistic levels
    of about -0.5 to -0.6 (winter) with a marked seasonal cycle. Also a cooling of 2.2C in
    about 15 years of data at the Summit won't be significant.  Not all Greenland has cooled
    either since the 1940s - mostly in the SW.
     One big question is whether anyone would know if some ice had melted 6K yrs ago. Can't
    tell from the Summit cores. Lower elevation cores don't go back that far, so may have.
    Cheers
    Phil

     Phil, Sarah,
     Do you believe this about Greenland cooling? I though there had
     been an increase in ice calving. If so, what causes calving? Is it
     SSTs, or is it dynamics of ice responding still to the early 20th
     century warming in Greenland?
     Tom.
