ABSTRACT
An analysis of the impact of carbon dioxide on global warming was performed using global average temperature data covering the last 158 years, along with corresponding atmospheric CO2 concentration data. A statistically significant correlation between the two was developed and used directly to calculate values of the key CO2 climate sensitivity factors (CSFs). When CO2 was treated as a proxy for all possible radiative and feedback forcing agents, an upper bound for the temperature rise due to a doubling of CO2 concentration was found to be 1.92 K. When the impact of CO2 alone was separated out from that of other radiative forcing agents, its CSF was found to be 0.250 KW-1m2, and the 2xCO2 temperature rise is 0.96 K. These values are less, by more than a factor of 3, than those typically reported from use of general circulation models.
