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.
