If we scale our total atmosphere at 100mm high (graphic on the left) then the total CO2 in it is 0.0566mm high - quite invisible! (total atmosphere is 5,300,000 Gt, total CO2 is 3,000 Gt) so let’s increase the scale by a factor of 10, scroll down please . . . .

The scale now is 10 times bigger than the previous one: 1,000mm in height now scroll down for a bit . . . . quite a bit in fact! Welcome to the bit that all the fuss is about . . . Now, total atmosphere = 1000mm, total CO2 = 0.566mm. This can still barely be shown at this scale, but it is visible. Man-made emissions are still not visible though. To see the proportion of man-made emissions a little better, we need to blow up the scale by a further factor of 10. So now, total CO2 is 5.66mm high (red) and man-made emissions are 1.58mm high (yellow). This equates to 0.0164% by mass of the total atmosphere, almost invisible!

Can anybody explain to me how such an insignificant quantity of a gaseous substance can possible heat up the entire column of air? All arguments are more than welcome, especially ACTUAL PROOF!!! back to top of page from here.
