92.2 Gt - C
= 70 (preindustrial) +22.2 Gt - C to 80 Gt - C
= 60 (preindustrial) +20 Gt - C while the absorption by terrestrial
vegetation went up from 122.6 Gt - C
= 120 (preindustrial) + 2.6 Gt - C to 123 Gt - C
= 108.9 (preindustrial) + 14.1 Gt - C; the
change from 2.6 to 14.1 reflects a reassessment of the fertilization by the additional CO2
in the air since the 277 ppm assumed for the «preindustrial», but is still a factor 2 or 3 lower than the observations between 1960 and 2010 related by the papers of Graven & Keeling, Myneni, Donohue, Pretzsch, Hansen and Sun referenced at the end of card n ° 1 (footnote 19).
