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 CO 2 concentration data. A statistically significant correlation between the two was developed and used directly to calculate values of the key CO 2 climate sensitivity factors (CSFs). When CO 2 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 CO 2 concentration was found to be 1.92 K. When the impact of CO 2 alone was separated out from that of other radiative forcing agents, its CSF was found to be 0.250 KW −1 m 2 , and the 2xCO 2 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.
