[edit] Description
This figure shows apparent correlations between historical CO2 and temperature records based on Antarctic ice cores, providing data for the last 750,000 years. The data has been normalised so as to be presented on a common scale. Current CO2 concentrations (380 ppmv) would be 5.48 (3 s.f.) on this scale.
Template:If possible, please quote values for 1)CO2 mean, 2)CO2 standard deviation, 3)Temperature mean, and 4)Temperature standard deviation. This will assist interpretation of the normalised plot
