gee I wonder why climate didn’t line up 1:1 with CO2? When a dependent variable has multiple known causal factors, there is no reason to expect a linear correlation between it and any particular causal independent variable in an uncontrolled setting

the paper this data comes from: https://sci-hub.mksa.top/10.2475/ajs.301.2.182 the authors explicitly state: "Thus, exact values of CO2, as shown by the standard curve, should not be taken literally and are always susceptible to modification. Nevertheless, the overall trend remains. This means that over the long term there is indeed a correlation between CO2 and paleotemperature, as manifested by the atmospheric greenhouse effect."

heres what a chart looks like when its not completely fucking useless: CO2 and temp moving together ., cry more retard, everything you post is embarassing you further
