Illumination of the earth by the sun:1. More heat received at the equator than at the poles2. Solid earth receives more heat by radiation than it radiates backRESULT: CONVECTIVE HEAT TRANSPORT FROM EQUATOR TO POLES THROUGH AIR AND OCEANS

To go from atmospheric CO2 concentration change to climate change, we need to know the climate sensitivity parameter, .

The common approach is: Ts = ForF/Ts = 1/ where

F is the ‘radiative forcing’ caused by the increased CO2 concentration. The value of F can be calculated from the increase in CO2 concentration using the deBeers law.

Ts is the change in the surface temperature of the earth

We can solve for by taking the first derivative of Boltzman’s LawF = Ts

4 or dF/dTs = 4F/Ts leading to a value of 0.3 K/Wm-2.

This approach is the most fundamental response function and uses zero climate feedbacks! Most climate modellers use 0.5 K/Wm-2, incorporating various positive and negative feedbacks.
