That is a fundamental misunderstanding of Thermodynamics. There is a two way flow of radiation between the surface and atmosphere. 400w up and 340w down for a net of 60w up. You can't have one without the other, they happen at the same time.You think CO2 warms the planet, so much it adds I think twice as much heat as the incoming rays of the sun? Or something like that from the models you've posted. I've even stated to you that with your thinking of how CO2 interacts with the atmosphere we'd have perpetual motion! I will say one more time that as of my time in this forum now five + years, not one individual has posted one iota of observed evidence of CO2 impacting our temperatures.
You don't seem to be capable of catching on to concepts. Should I really bother explaining it all again when you will just ask the same questions next time?
The surface and the atmosphere both have stored energy. At night (no incoming energy from the Sun) they both cool by radiation. The surface feeds energy into the atmosphere and some escapes directly to space through the atmospheric window. The atmosphere radiates its stored energy in all directions, some returns towards the surface. This returned energy balances out some of the radiation loss from the surface therefore the surface doesn't cool as fast as it would if there was no atmosphere. But both are cooling by passive diffusion of energy THAT WAS ALREADY THERE.
The sun actively adds energy to the system. New energy, that gets stored. The surface temperature goes up, chasing the equilibrium temperature where input equals output. This is active heating, not passive redistribution, although that is still happening as well.
You made a comment on energy coming back from the atmosphere being twice the amount being received by the Sun. That is a fundamental misunderstanding of Thermodynamics. There is a two way flow of radiation between the surface and atmosphere. 400w up and 340w down for a net of 60w up. You can't have one without the other, they happen at the same time.
Now the question is, has this been measured?
from three different scientists:
“[T]he absorption of incident solar-light by the atmosphere as well as its absorption capability of thermal radiation, cannot be influenced by human acts.” – Allmendinger, 2017
“[G]lobal warming can be explained without recourse to the greenhouse theory. The varying solar irradiation constitutes the sole input driving the changes in the system’s energy transfers.” – Blaauw, 2017
“The down-welling LW radiation is not a global driver of surface warming as hypothesized for over 100 years but a product of the near-surface air temperature controlled by solar heating and atmospheric pressure.” -Nikolov and Zeller, 2017
