"Feynman" has nothing to do with it.  red herring.

consider the magnitude of each process, radiation vs convection.

well, look at water vapor, the bands that it absorbes IR and reradiates, 
and sum that up over all the optical/ir bands, it dominates over CO2.

why is water vapor as a greenouse gas that not discussed that much?
1. because there is nothing man can do about it
2. Venus, the dramatic result of a condition of trapped heat, has CO2 as 
its major cause, little water.
