Thanks; interesting that the CO2 line follows, rather than leads the temp line especially in the last 10,000 years with the temperature peaking at +2 with a lull of 255ppm CO2 and the temp line has peaks where little movement is shown on the CO2 line, artefact perhaps?

I just read a recent post on this which was great. And again I'm lucky, I found it:

What does the lag of CO2 behind temperature in ice cores tell us about global warming?

Certainly CO2 is not the only thing that affects global temperatures, but it's an important factor.
