We could stop polluting the earth.
But, as you said, CO2 is not a pollutant, does not cause global warming, nor cooling.
The "science" behind climate change has never been released for anyone else to scrutinize. And really, if there was a run-away event, then it would have likely happened all ready. On the contrary, the earth shows an immense ability for self regulation.
Taxing CO2 is just a tax on living with electricity.
It is about getting the people to pay more for less.
That people who believe in actual science are called science deniers... then what?
Indeed true. I continue to shed light on this and hope to perhaps un-brainwash a few. Thanks my friend @builderofcastles
