   Professor Haigh,

   I have been corresponding recently with Phil Jones of UEA regarding the Figure on his
   website showing the global temperature record to 2006. This and other similar records show
   a definitive slow down in the temperature rise since about 2001 which is also evident in
   some of the Figures in the IPCC AR4 WG1 report without comment. Also noticeable in AR4 is
   the reduction in solar

   forcing from the TAR apparently due to the preference for a low TSI composite and a low
   reconstruction from the Maunder

   Minimum in Section 2.7.1.

   This position seems to leave the IPCC in some difficulty in explaining the current Global
   Temperature data with the

   atmospheric CO2 levels continuing the steady rise. My question to you is whether the
   indirect effects of solar variability or

   solar amplification could be contributing to this trend as solar cycle 23 reaches a minimum
   about now. I have noted your 2006

   Space Science Review of this developing subject and wondered if recent developments could
   suggest a significant impact on the

   current tropospheric temperature record.
