Comments P.127 left column bottom paragraph: "On the other hand, current worldwide deforestation contributes 0.8-2.5 x 10^14 mol CO2/yr (primary source Houghton et al., 1991) to the atmosphere, which is rather the reverse of humus formation. A more precise figure for deforestation and biomass burning, offset by reforestation and biomass regrowth, of 0.52 x 10^14 mol CO2/yr is given by primary source Bouwman et al. (1992)."
