| contents | The main determinants of Earth's absolute surface Temperature, T, are the solar constant, S, the Bond albedo, A, and the effective emissivity for thermal radiation, e. In this note we assume that the value of the effective emissivity, e = e(C), is determined by the atmospheric concentration C of CO2. We show that the solar constant is most important, the albedo is second, and the CO2 concentration is a distant third. |
