Air contains 78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.039% carbon dioxide, and small amounts of other gases. Please have the man-made global warming alarmist explain the comparison between the man-made components of 0.039% of the atmosphere and the naturally occurring components. Then have them explain how 0.00X% of the man-made contribution causes "climate change". I guarentee you, not a single person will be able to do this.
