We have 600 million years of information about the climate at CO2 levels up to 6,000 ppm. For example, there was an ice age during the Ordovician with CO2 levels 20X higher than they are today. Huge coral reefs formed during the late Permian with CO2 levels 10X higher than today. There is no indication in the historical record that higher CO2 levels kill coral reefs or are associated with monster hurricanes.
Many climate scientists aren’t interested in empirical data, choosing instead to use climate models which can be tuned to generate the results they want to see.
Man was not around, so CO2 was at that time uncorrupted. After Adam and Eve ate the apple, they farted, and greenhouse gases have never been the same.
Obviously, only Capitalist CO2 is bad. I’m doing my part: I’ve been trying to inhale with Capitalist thoughts, exhale with Socialist thoughts.
SUVs and pickups owned by evil white Republican males are still no match for dinosaur farts.
