Your hypothesis states: "deminimus increases in Earth's atmospheric trace element CO2 causes immediate and cataclysmic changes in the climate"
Show me one experiment, just one that shows this happens.
We're not talking about a 97% CO2 atmosphere, we're talking about barley perceptible increases from 280 to 500PPM.
Show me ONE experiment where this was demonstrated.
Do the experiment I posted above yourself Frank, you can literally see the difference.
But putting that aside, you have a logical fallacy going on here.
We know for a fact that Carbon Dioxide creates a "Greenhouse" effect.
Though the atmosphere is certainly not 97% carbon dioxide, the carbon dioxide that is in the atmosphere would have the same effect whether it was diluted or not, unless there was some other circumstance that countered the effects of the increased Carbon Dioxide levels.
On what basis are you forming your opinion, therefore, that lessening the level of Carbon Dioxide from 97% would eliminate the greenhouse effect altogether?
