I author of the article provides sources and data. Where is yours? As a physicist, I find the arguements quite reasonable. Water vapor is by far the predominant "greenhouse" gas, and its contribution to the temperature of the Earth overwhelms all other gases, whether that results in a temperature slightly above absolute zero or the comfortable temperture we actually have. The isea that man's miniscule contributions to CO2, which is a miniscule component of the total greenhouse gases, could make large swings in the global temperature is absurd. FInally, all of this is, as shown by the data, driven inexorably by the Sun. The Earth's temperatures track the Sun's activity whether we want it to or not. ALlgore is a fool, and he is dragging much of the climate change community into his fools paradise!
Can't disagree with that. I was wrong about N2O, BTW. Well, sort of. It is dinitrogen oxide, but it's also correctly identified as nitrous oxide. I should have googled before posting.
From 10% to 25% depending on who you talk to. Small but not miniscule.
