> A 30% bump in plant carbon sinking Plant growth by itself is not a carbon sink. It just adds to the "buffer size" for the short-term carbon cycle. For some of that carbon to be "sunk" it has to either be removed and used/stored in a way that doesn't put that carbon back into the atmosphere, or transformed into long-term stable humic and vulvic substances, or buried in an anaerobic environment under pressure so it'll eventually turn into petroleum. Also the CO2 fertilization effect also has negative consequences... enough so that it's really far from clear whether it's a net postive, even a small one. For one thing it's one of the reasons why modern food has significantly lower nutrient density (plants, including crop plants are growing faster, but the additional mass is almost pure carbohydrates, very little additional proteins, minerals, etc.). And in the tropical rainforests, the plants that are most benefiting from CO2 fertilization are fast-growing vines, and they are literally choking off tree growth (there have been papers published about this).
