Compare log2 of atmospheric CO2 vs. global mean temperature over the last 1000 years. We expect that raising CO2 will raise temperatures at a logarithmic rate because of the greenhouse effect. HOLD SPACE down to see CO2/temp/year at mouse pointer. LIGHT GREEN=measured temperatures DARK GREEN=historic temperatures derived from paleoclimate proxies. LIGHT RED=measured CO2 DARK RED=historic CO2 derived from ice cores.
