So you see what we've got here? The end result is that little black square in the middle of the yellow square (directly above). That my friends is man's contribution of CO2 into the earth's atmosphere. I had to break it down in this way because, at the starting scale (the blue square up there), man's contribution would show up as an area much smaller than a period (.) on this page.

This is why I say that nothing about Anthropogenic Global Warming (or Climate Change or whatever they are calling it these days) passes the common sense test when you look at any of the real numbers. This also reinforces the much more commonly held view (among the real adults) that the sun and the oceans are the primary drivers of climate temperature. Perfectly natural.
