Terrestrial ecosystems remove about 30 per cent of the carbon dioxide emitted by human activities each year， yet the persistence of this carbon sink depends partly on how plant biomass and soil organic carbon stocks respond to future increases in atmospheric CO2. Although plant biomass often increases in elevated CO2 experiments， SOC has been observed to increase， remain unchanged or even decline. The mechanisms that drive this variation across experiments remain poorly understood， creating uncertainty in climate projections. Here we synthesized data from 108 eCO2 experiments and found that the effect of eCO2 on SOC stocks is best explained by a negative relationship with plant biomass: when plant biomass is strongly stimulated by eCO2， SOC storage declines;
