Crick- you are correct in saying that the amount of energy sequestered in heatsinks has increased after the addition of CO2. That energy is what powers increased surface temps, convection etc.
Thank you
It will not increase TOA LW past the equilibrium point.
I never said it would.
What would increase LW (or SW) is the case of the heatsinks releasing energy, which would mean cooling or some other loss of energy in the heatsinks.
Ian, you're starting to sound like some of your less rational cruising buddies. "What would increase LW would be if we had a giant Westinghouse oven cranked up high" Do you have some mechanism that would cause the atmosphere to start releasing heat all by itself? If so you've probably got a Nobel prize coming to you and a fortune as you replace the world's refrigerators and A/C units.
a simple example is the fact that the atmosphere puffs up during daylight hours, storing energy as gravitational potential. at night the atmosphere gives up this potential energy. this heatsink moderates the temperature differences between day and night. is this the type of example you were looking for?
it is far easier to recognize atmospheric interference in SW. clouds can reflect solar, which both decreases energy entering the deep layers and increases the SW leaving. your reference to an air conditioner is apt. surface energy is the source of evaporation, which powers convection, which leads to cloud formation. this is a much more efficient pathway to lift energy past the surface boundary than is radiation. it is interesting that both the formation of clouds, and the timing of the formation have an effect on energy loss to space.
