Sorry, no etymologies found.
Water molecules scatter blue wavelengths by absorbing the light waves, and then rapidly reemitting the light waves in different directions.
What matters is how effective the gas is at absorbing IR radiation and reemitting it toward earth the true greenhouse effect.
Now, nothing prevents a molecule which absorbs an IR photon from immediately reemitting it or a photon of some other energy; as long as the molecule has the proper internal energy to do so, except that the mean time between collisions in the trophsphere is much shorter than the mean time for a molecule of CO2 in an excited state to emit a photon.
Again why won't anyone call for action on pyriolyzing the massive messes of organic wastes as a means of curbing their reemitting GHGs, while also destroying germs, toxics and drugs that are escaping to pollute more water systems?
The growing of biomass for ethanol fuel is foolishness when we have huge amounts of biomass in our massive ever-growing messes of organic wastes and sewage solids, much of which we allow to get handled so that natural biodegrading brings about needless reemitting of much of the GHGs that nature has so nicely trapped for us.
In the time interval between absorbing and reemitting radiation, CO2 molecules allow IR to pass them by.
Gonzalez also says that plate tectonics plays a vital role in the carbon cycle, subducting carbonate minerals into the mantle and then reemitting them from volcanoes as carbon dioxide.
