CO2... I've released enuff into th' atmosphere to supply a rain forest. Every li'l beer I open. "PSST!" It IS heavy but this "soup" we call "air" is a real mix. Mostly Nitrogen, too. Back when we were pokin' holes in th' Ozone layer with CFC's, DuPont was realizing their patent rights were about to expire on THAT (propellant) stuff. Also known as "Freon".
This "Mother Earth" will indeed shrug us off like a bad case of fleas, then continue on her journey. Politics is an engaging passtime for a LOT of humans, most of whom THINK their "team" has all the answers. Hard science seems to be ignored in the main as everything from "too geeky" to "unproved". Tilting at the Collective windmill is still an exercise in futility. If the lemmings wanna charge the cliff edge en masse, I ain't gettin' in the front of th' herd to try dissuadin' 'em. I'd rather stand aside an' holler: "RUN!! RUN FASTER ya SLUG!! THAT sumbich is AHEAD of ya!!!"
Muddying the Forum with it is counterproductive, IMO. I'd rather post Jimmy Buffett's "Fruitcakes" lyrics. :smirk:
