Almost everyone agrees that CO2 and temperature are correlated in the historical record using ice cores and other methods. The science is clear. There have been legitimate concerns about causality, though. So I'm surprised that you are attacking the correlation and not the causality. If you don't believe there's a correlation, then perhaps you should do a bit more reading. The science and statistical analysis is compelling. ncdc.noaa.gov "Nonetheless, even with the large sampling variations that arise in the 100 year window case, the relationship between recent warming and increasing greenhouse gas concentrations is the dominant statistical feature. It is evident that the inclusion of a representation of the lagged response of temperatures to forcing heightens the evidence for a recent anthropogenic impact on 20th century climate beyond that presented in MBH98." ncdc.noaa.gov "One of the most remarkable aspects of the paleoclimate record is the strong correspondence between temperature and the concentration of carbon dioxide in the atmosphere observed during the glacial cycles of the past several hundred thousand years. When the carbon dioxide concentration goes up, temperature goes up. When the carbon dioxide concentration goes down, temperature goes down."
