James F. Pankow was born in 1951 when atmospheric global CO2 levels were ∼312 ppm. 312 ppm!

5. Right. Ignore the people that

challenge your biases. That's real science-y. The CO2 numbers are crucially important. I've been chanting the ever rising CO2 ppm to everyone around me since 1968. I remember it being around 340, and everyone who understood it knew where it was going. I've been preaching the cascade effects of crossing the 2C increase in average surface temps for about the same time. Sea ice area, changing deep sea thermoclines, planetary albedo figures, the gigatons of unexpressed methane clathrates, all of that. But just repeating these numbers is not persuasive. After 30 years of study you should know that. After 53 years of it I certainly do. So go ahead and ignore me and just keep on reciting the ppm, and if that's not successful then demean the people that have come before you, that's bound to work.
Ignoring me doesn't make me the ignorant one, genius.
