And besides, climate change is not the only part of modern ecology. You know very well many companies would dump massive amounts toxins for much cheaper in destructive ways if they could get away with it. And CO2 plays a minute roll in global warming compared to many gasses
It is absolutely true that CO2 plays a tiny amount compared to other gasses. But this infact argues that AGW is incorrect; not correct. CO2 and H2O have overlapping IR absorption bands. The amount of water vapor in the atmosphere is between 2-3%. The amount of co2 is .04%
Rule of thumb - 96X more contribution to global warming.
Now alarmists like to pretend that the amount of water vapor remains more or less constant - and therefor warming must be due to the increase of Co2. But is it really?
What if we had an increase of temperature - or an increase in cloud cover.
Or - if you look at our hydro carbon burning, and do some back of envelope calculations, you find that when we burn CxHy (fossil fuels) we form not only Co2, but H20.
How much water do we form? Roughty 22,000,000,000,000 lbs. 22 trillion pounds of water added to the atmosphere - every year. Now, of course it rains out - but to suggest that it rains out - misses the point.
A). Latent heat of condensation adds huge amounts of energy to the atmoshere.
B). It increases the amount of rainfall, and clouds.
And clouds .. make the earth warmer.

When a greenhouse gas molecule absorbs infrared energy - it only has a few things it can do with that energy.
It can re-emit it.
It can get trasnlated into velocity
It can get translated into rotation
and it can be translated into vibration.
It can also get translated into chemical reactions -
Low in the atmosphere atoms are close together - constantly "hitting" each other - and when they do that energy is translated. So in the lower atmosphere this gets translated into conveying energy to surrounding atoms.
In the upper atmosphere, there is a long time between interactions of atoms, and radiation plays a much greater roll.
So the solar intensity in the upper atmosphere is 1360w/m or so; at ground its 1050 or so. In the upper atmosphere gasses serve to cool the planet by re-radiating energy into space.
In the lower atmosphere, greenhouse gases warm the atmosphere, but again according to a logarythmic function.
So here are some things that have never been successfully modelled:
As you increase CO2 concentrations, it migrates up the atmospheric column. It cools in the upper troposphere, warms in the lower - but the net effect as well as the net incremental effect is not known.
