Rainfall energy input and climate sensitivity

byEarth current average annual rainfall is 39inchs. So multiply the volume of water falling per square meter, 970kg, the specific heat of water times the average 82.5 degree plus the heat of vapourization, gets 2.526GJ per year, or 80.11 Watts per square meter. Entering in our formula derived last time.
Where the 1, is the base climate sensitive as Wikipedia. The the 0.07, is the exponient of the increase in rainfall due to each extra degree of heat increase. Thus for every 6.6 Watts per square meter the atmosphere absorbs due to C02, 1W goes into raising the temperature one degree, and 5.6W goes into increasing rainfall. Given we before numerically calculated, that doubling CO2 to 800 parts per million (volume), absorbs 1.1 Watts per square meter. The actually amount of temperature rise is only, 0.167 degrees (Kelvin or Celesis).
