Science is proven through demonstrations of experiments.
If this was a slam dunk. The evidence would make it a slam dunk and debate would end.

The science of what has happened and what is happening to the atmosphere is quite repeatable and quite easily documented - the hitch comes when folks with a vested interest start trying to predict the future based on the science of what has been and what is happening to the atmosphere.
The extremes are " no effect" and " The Sky is Falling!"
Who I believe depends a lot on the vested interests behind the mouthpiece doing the predicting. As with ALL things political, if you want the truth, follow the money.
