Comments P.129 right column bottom paragraph: "The potential oxygen equivalent of the world biomass and terrestrial humus (Fig. 9) is estimated (primary source) to be equivalent to 1.8 x 10^17 mol O2 (or 0.48% of the total oxygen mass). This figure has some consequences with respect to oxygen: 1) Since there exists a 1-to-1 conversion (and vice versa) of O2 to CO2 on a molecular and vol % basis [see formula (4, above)], O2 fluctuations in the atmosphere are very limited and restricted by equal CO2 vol % fluctuations over short time scales."
