As I understand it the following factors should be taken into account 1) all c02 is 0.038% of the atmosphere, 2) that some 3% of that fraction is annually anthropogenic 3) c02 delays outgoing heat at 15microns in the spectroscopic absortion range 4) outgoing radiation is between 0 and 1% of the heat budget, 5) c02 moves bewtween air and oceans, soils and other sinks quite quickly. 6) There are 3067 gigatons of c02 in the atmosphere 7) the first 50ppm of c02 delays that fractional (5% of 0-1% heat budget) heat transfer into space, and anything additional only increases the metric range of this delay, and not the heat absorption, due to its logarithmic absorption factor. 8) only the carbon particle, and not the 2 oxygen particles have this effect. 9) given natural variability, over 98% of carbon dioxide fluctuations are naturally occurring. 10) At a constant temperature, the amount of a given gas dissolved in a given type and volume of liquid is directly proportional to the partial pressure of that gas in equilibrium with that liquid. (oceans), and finally 11) that oceans and vegetation absorbs c02 exponentially and not logarithmically. Sincerely Scott Betts
