What is this nonsense? This chart is meaningless. Water vapor is a better absorber of IR radiation than CO2 by a factor of 6.83 when you analyze the spectrum between 0.5 and 15 microns in the light of E – (h x c)/w where E is energy, h is Plancks constant, c is the speed of light and w is wavelength. See the Absorption Chart at the American Meteorological Society website. The truth of the matter is very simple.
Um, Guys, first off, commenting on a picture is kind of pointless. Not much traffic here, it is all on the articles.
Second, there is a whole lot less water at height than near the ground. It is hard to have an effect from water in the stratosphere when there isn’t hardly any there. That is what this graph shows. Water is plentiful down low, so dominates the troposphere (where CO2 is meaningless). Up in the stratosphere, CO2 is not having much in the way of collisions to dump energy, so has time to radiate, and there just isn’t enough water to matter much at all. CO2 is a net cooling entity in the atmosphere. That it is just a few PPM implies it doesn’t do much in total, but what it does do is cool the stratophere a tiny bit, and do nothing in the convective troposphere. (How David H gets GWA out of that is beyond me…)

Amen Adrian,
This is just some GWA bull working with his comrades to tax the only thing left they haven’t taxed.
The Air.
