I note that this article compares changes in CO2 in the atmosphere with changes in temperature. This is similar to taking first differences, which statisticians do to make variables stationary. This approach is used for analysis by polynomial cointegration, for which Engle and Granger shared a Nobel Prize. http://en.wikipedia.org/wiki/Cointegration

Analyzing GHG and global temperature, an Israeli group concluded, "We have shown that anthropogenic forcings do not polynomially cointegrate with global temperature and solar irradiance. Therefore, data for 1880–2007 do not support the anthropogenic interpretation of global warming during this period."
