Thanks for the links, all....
..especially for the comments in the articles.
The argument basically boils down to this... it is all a delicate balance, and we are destroying that delicate balance.... but when nature does something truly awesome and powerful, like liquidate a mountain cap, or constantly pump out gasses from volcanoes that would make all the Chinese coal plants blush with jealousy, or the delicately balanced volcanoes underseas, then it has little to no effect, because that doesn't fit with current environmentalist models and observations.
An interesting comment was about Henry's law, and after using Henry's law, someone said "well, that simply doesn't fit observation". Well, Henry's law is an absolute chemical law, so if the observations don't fit, there is something wrong with the observation, not the law.
And what about water vapor... isnt that the biggest greenhouse gas... and it is about 20 times more common in the atmosphere than CO2.
Therefore humans made the Earth and its chemical reactions are all human made? You do realize posting a chemical formula, snarky as it may be, and truthful as it may be, adds nothing to the discussion of whether it is man made or not, do you not?
Oh, and there was lots of proof through observation of Eugenics too.. .and it was popularly accepted almost world wide. Oops.
