Actually I've reread Gavin's letter to Klotzbach a little more carefully and he gives the GISS - ER figures: As might be expected, the land temperatures rise faster than the global mean or ocean values (0.26 deg C / dec vs. 0.17 deg C / dec and 0.14 deg C / dec) So land to
ocean trend ratios are: GISS - ER: 1.9 (1979 - 2005) SAT obs (1979 - 2008) HadCru: 1.6 GisTemp: 2.3 NCDC: 2.8

First I calculated the land - only,
ocean - only and global mean temperatures and MSU - LT values for 5 ensemble members, then I looked at the
trends in each of these timeseries and calculated the
ratios.
My attempts to determine the
ratios and differences between the observed
ocean air versus
ocean SST temperature
trends to compare with the model results were limited by the sparseness of the observed data.
