Abstract

Estimates of the atmospheric temperature changes due to a doubling of CO2 concentrations have been with a static radiative flux model. They yield temperature changes >0.25 K. It appears that the much larger changes predicted by other models arise from additional water vapor evaporated into the atmosphere and not from the CO2 itself.
