    394 C'est une simu où seul le rayonnement voit le CO2, la végétation et la biogéochimie marine voient une valeur fixe (en général préindustrielle) de CO2.

     398This is a simulation where the radiative code takes into account a varying CO2 concentration while the vegetation and the marine biochemistry are only fed with a constant CO2 concentration value (in general set to pre-industrial value).
