Only convection and conduction warms the atmosphere. The atmosphere is transparent to LWIR and does not warm it.But we were talking about radiation!!! It is radiation emission impinging on molecules that gives higher average velocities that in turn increases the temperature. Therefore absorption of radiation warms the atmosphere. Talk about spoon feeding physics!
You have no concept of LWIR and its FREQUENCY. You folks post up the bandpass graph and you fail to understand that 99.4% of energy emitted from the ground is emitted in a LWIR band above 10um. Only water will react to it in our atmosphere and then only long enough to cool due to the evaporation process rendering it impotent (which is why there is no tropospheric hot spot).
Tell me, Do you think an object radiating at -80 F (12-16um frequency) can warm an Object that is 32 deg F? Trenbreth's cartoon is a fantasy derived from failed QED modeling. Less energetic (lower frequency) energy causes cooling in more energetic (higher frequency) molecules.
This is why I sit back and watch you folks go round and round about energy transfer that not one of you can prove and empirical observations say is not happening. Whom to believe, Your UN-provalbe mathematical constructs which fail empirical test or observations which disprove your theroy/hypothesis.?

Tell me, Do you think an object radiating at -80 F (12-16um frequency) can cause an Object that is 32 deg F to cool more slowly than if the -80F object weren't there?
