There is a popular fantasy that the earth is 33C warmer with an atmosphere than without due to the radiative greenhouse effect, RGHE and .04{154653b9ea5f83bbbf00f55de12e21cba2da5b4b158a426ee0e27ae0c1b44117} CO2. Let’s start at the very beginning, a very good place to start – or so I hear.
The 33C difference is between an alleged average surface temperature of 288K/15C and 255K/-18C, the alleged surface temperature without an atmosphere. Let’s take a closer look. Just which average surface temperature? The two extremes? (71C + -90C) / 2 = -10C?
