Regardless of the cause of climate change, on any time scale (even if it is a 100% natural cycle and human effects are zilch in the grand scheme), pollution is icky and hey, I'm walking^W living over here.
With respect, 2/3 of the carbon dioxide out there is purely natural such that “icky” isn’t an appropriate foundation for the relevant public policy
With respect, they said pollution is the icky part. I’m not aware of any major industries that are responsible for an appreciable amount of CO2 emissions and no other pollutants/icky stuff, but I’d love to be proven wrong about that.
