Can you not read your own comment #2? I quoted from it in my comment #5. Once again, in your own words:

“...lower the Earth’s surface temperature by 4.5 watts...”

Sorry for your misunderstanding.

Yes I said that but it is true surface temperature is determined by how many watts hits it but I did not say it is a measurement of that temperature - negative 4.5 watts will lower the amount of solar energy hitting the surface of the earth thereby lowering the temperature ... good grief!
