Very stupid of you, Walleyes. For if you look at the graph, the variation in CO2 is about 282 to 272 ppm. And the 282 was during the MWP, while the 272 was during the Little Ice Age. Yes, I will post that site and it's graphs again.
Ice cores, carbon dioxide concentration, and climate
Nice attempt there olfraud but that's not the study I'm thinking of. Post the correct one. Chicken!
The question is why should I accept one study over possibly thousands that say otherwise? Those tree and plant "studies" don't show it as high as today, but higher then the ice cores, yes.
The question is why would you use anything from a group that has willingly, knowingly, and repeatedly falsified data?
