Nice chart. Didn't know that million of years ago, "they" had little weather men with their stone tablets recording CO2 and temperature variations.

It's called ice,(VOSTOK antartica) containing microscopic bubble samples of the atmosphere.

PS. You might try reading the article on Coal strata as well. Amazing how CO2 content of the atmosphere affects the growth of vegitation, and the depostitation of carbonate deposits in sediments.
As far as temperature, isotope ratios serve as excellent proxies for temperature.
