First (a) calculate the rate, in W/m2, of IR energy emission of a blackbody at 287.2 Kelvin (a value that will come up from the MODTRAN model in a couple of minutes). The value of sigma is 5.67 x 10-8 W / (m2 Kelvin4). Assume an emissivity of 1.
Now raise the temperature by 1° C and (b) calculate the change in outgoing IR, in Watts / m2.
You now have the change in Watts / m2 per 1° C. We will now rearrange this number into a ΔT2x climate sensitivity that has useful units of °C / (2xCO2) - the increase in temperature (°C) per doubling of CO2 (2xCO2).
Hint: Remember the radiative forcing per doubling (2xCO2) of CO2 is 4 Watts / m2 per doubling.
(c) What value do you get for ΔT2x?
