Let me post again a poser from the past re: simple maths.
CO2 is expressed, for convenience' sake, as Parts per Million of mixed atmosphere.
That value is currently at around 380 ppm. This portion of the total atmosphere is rising, at 2ppm/year, or so it is said.
Once again, since the proportion of CO2 is increasing, what are some other components doing? Either the atmosphere can be measured that finely, or it cannot.
What other gas is losing ground? If that cannot be answered, then no attention can be wasted on CO2 alone. Is it Oxygen? Water? Nitrogen? Unimportant?
Once known, I would lke to see that poor gas get some attention, perhaps some massive grants, or at least a heads up to AlGore, Junior.
CO2, not only a pollutant, but a rude one, at that.
