Here's a write up on A Petit paper at a denier web site: http://www.co2science.org/scripts/CO2ScienceB2C/articles/V2/N12/C1.jsp They have their elbow in their ear by the time they finish trying to twist Petit to their cause.

I have not looked at the orginal paper. Or maybe since they are so close in time, CO2 could not be the initial forcer. The quote says that CO2 forcing lags orbital forcing, not that CO2 lags temperature. > More interesting is the > following downtrend, which certainly appears to have CO2 reduction > leading temperature reduction by several hundred years. > > However, this is only one of the three papers on just the Vostok ice > core.
