certainly discredits your position that temps lag well behind increases in atmospheric CO2 lol Sounds like you're arguing with yourself! You really need to slow down and understand what you're reading before you go off half cocked.

.....I think you said 800 years. So all and all, I think its a nifty little chart.....direct and to the point! ;-) Here's a nifty chart that shows planet temps started rising about 800 years ago (aka the medieval warm period) and you've shown the chart regarding CO2 lagging by 800 years - which proves my point.

Another nifty chart: You can see that the Antarctic temperature starts to change first, and CO2 responds with a 800-year lag. Methane is still correlated with both. The graph is not new. Today, we have many more accurate graphs of this kind, many of which are from more distant past. We also have a more detailed analysis by Stott et al. (Science 2007) of the end of the last ice age 19,000 years ago where CO2 lagged by about 1,000 years, too. The explanation is obvious: oceans are large and it simply takes centuries for them to warm up or cool down before they release or absorb gases.
