I see the scientist among us has arrived. Simple math too tough for you Burb?
What is the composition of the Earth's atmosphere? Guessing you are not a diver, it is 78% Nitrogen, 21% Oxygen, and then mostly Argon. Somewhere in there we have one of the smaller components of our atmosphere at a whopping f%ck all percent, which then according to the fear mongerer's models doubles to OH MY F%CKING GOD. Yet it still only yearns to scratch the ass of 1% of our atmosphere. If this were a pie chart you could not even see the sliver. A single pixel line would be too thick. It could quadruple and still be so far from even qualifying for a rounding error, yet this gas and its miniscule increase is the culprit for the "global" changes in climate?
Please. Pull the other one. I mean really.
