I have recently come across this fascinating video over at Bishop Hill. The video shows Professor Vincent Cortillot asking some very basic questions about the temperature record that is promulgated by the IPCC, and shows examples of regional temperatures that appear to contradict the IPCC records. With regards to any correlations between CO2 and the temperature records, he notes that there appears to be none. Instead, he examines a range of other possible influences on climate, for example that big ball in the sky that seems to make us feel warm when we can see it. Yes, that will be the sun.
I have not seen any examinations or comments yet on the science that he is proposing, but he appears to make a strong case. In all cases, I think it is worth watching in full, so have embedded it here.
