" that all previous global warming periods so far have preceded the increase of CO2 (by aro 800 years) "
Because, you know, the dinosaurs were avid burners of fossil fuels... This has been only true relatively recently. For example, Eocene thermal maximum almost certainly did not follow the "pattern" you describe.
Anyway, since you preferred to ommit any links supporting your claims, I dug them out for you. And, as usual, you just don't know what you are talking about, or you believe you can roll over 'the ignorants' with some kind of pseudo academic attitude. While that 5-9 degreeC Eocene spike didn't follow any pattern possibly understood today, it certainly wasn't caused or preceded by a CO2 spike, as your post obviously was poised to support.
At least for next time, how about doing your home work first and posting then, CJ?
Here from the conclusion of the USCS paper, link to which you find below, which holds CH4 realeases for being the most likely dominating cause of the Eocene warming spike 55 million years ago:
"If the temperature reconstructions are correct, then feedbacks and/or forcings other than atmospheric CO2 caused a major portion of the PETM warming.
The origin of this additional warming is unknown at present.
Possible causes of the excess warming include increased production and levels of trace greenhouse gases as a consequence of the climatic warming such as CH4;"
