cc: "Phil Jones" date: Thu, 21 Jun 2007 10:22:20 +0100 from: "Roger Coe" subject: Global Temperatures and Solar Irradiance to: 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.
