Possibly the most obvious place to look for man's impact on pumping «greenhouse» gases into the atmosphere has nothing whatsoever to do with carbon dioxide, but it has to do with water vapour.

So starting with water vapour as a Green House Gas: 1) The water vapour in the air (near the ground) is heated by the ground and the sun.

I have made simple calculations with a water vapour content of 1 % and find that liquid water has less volume than the equivalent number of H2O molecules in gas form.

And while it is true that CO2 constitutes around.04 % of the atmosphere, never the less it contributes around 20 % of the greenhouse effect, with water vapour contributing the other 80 %.

The fact that different absorbers contribute to the net LW absorption is clear from IR spectra taken from space which show characteristic gaps associated with water vapour, CO2, CH4, O3 etc (Harries et al, 2001; HITRAN).
