The more CO2 there is in the atmosphere, the more plant life will thrive and consume that CO2. The liberal predictions of catastrophe are completely unproven by science. As you said, CO2 levels have been much higher in the past than now, and life thrived. Like everything, global warming a political tool to liberals. They are scientific illiterates, and for them the only purpose of science is to use it as a political tool to push socialism.
I just love the dark comedy of image of dinosaurs running in circles on fire screaming and bellowing until they burn up leaving nothing but bones....
Wait that didn’t happen during those millions of years CO2 levels were 7-10 TIME HIGHER THAN TODAY????
Yet these same scientists are the same that recommend "bugging" old gas station sites in cleanup scenarios.
They will simply produce the results the government wants you to see. It's called "Selective Science Method".....aka.....lying your a** off.
