Odd, because the only sources I can find that CO2 doesn't have to do with global warming, are various right wing extremist blog
ell I posted one here but you seem to have missed it.

This is from Real Climate. You wont find a more staunch supporter of global warming

At least three careful ice core studies have shown that CO2 starts to rise about 800 years (600-1000 years) after Antarctic temperature during glacial terminations. These terminations are pronounced warming periods that mark the ends of the ice ages that happen every 100,000 years or so.
