That is the assumption by religion of globull warmers, no one really knows the linkage between CO2 and tempreture. Since increases in CO2 usually lags increases in tempreture, the relationship if any would appear to be opposite of what is assumed.
If you're still interested in discussion of the differences between glacial-interglacial transitions and the current climate regime, I'm game. Are you really interested, or are you just going to blow off any scientific explanations that I offer?
