I have delayed further comment in order to read the IPCC WG1 full report which is now available online with its excellent Chapter 3. The hadcrut3 data is shown to 2005 in for example Figure TS.26 together with decadal average values showing a clear reduction in the upward trend. However I have been unable to find any comment on the most recent data since 1998 and Figure TS.6 and elsewhere only emphasise the historical upward trend. There are several factors such as sulphate aerosols and indirect solar radiation discussed in the report which could be influencing this lower trend (I made it 0.119C per decade) but I have seen no direct comment in relation to the recent downward trend. This is important in view of the wide acceptance of the IPCC overall conclusions for government and international policies. and decisions currently being made. Perhaps you could share with me your own interpretation of the recent data given of course the short timescale involved. Thank you again Roger Coe
