The people foisting false science "facts", are not the environmentalists, but rather the energy companies. Big oil pays big bucks to put out this bullshit. Just take for example one little thing, an automobile engine. The modern auto-engine runs at 220 Degrees, the exhaust at the manifold runs around 700 degrees, now take that times, what, a billion automobiles, think thats not contributing and thats just heat. Hell all the cigarette smokers contribute a few thousands of a degree, especially in china. Now as for the Ozone, thats a no brainer, the polution from auto exhaust NOX, hydrocarbons and mostly Carbon Monoxide has contributed to that decline, only a complete Idiot or an oil company employee would dispute that. My question is this: why is anyone trying to debunk the facts of human interferance in the climatology of the earth? 4+ billion human bodies at 98.6 degrees must have a minute influence, let alone all the coal fired boilers and nuclear and natural gas fired boilers Ect. ad finitum, steel mills with cauldrons of molten metal at 1800 degrees+ etc. Someone can't honestly say that man is no contributer unless they are either, pick one: Blind deaf and dumb, stupid, or work for an energy company. Common sense should dictate the facts, but for some reason, I really don't understand, these otherwise bright people become dimwitted when this subject is trotted out....... Wake up, It's real, now lets try and figure out a solution before ViRedds house is under 6 ft. of water!
