Fig. 4

Contributions of each component to cumulative land carbon sink by the middle of the twenty-first century of top 20 countries by 12 ESMs in CMIP5 under RCP 8.5. The four components of land C sink are: production-driven change (∆NPP × τ0), turnover-driven change (∆τ × NPP0), interaction between production-driven change and turnover-driven change (∆NPP × ∆τ), and change in instantaneous C storage potential (∆Xp). NPP0 and τ0 represent NPP and τ in year 2005 (average of 2001–2005), respectively. ∆NPP, ∆τ, and ∆Xp represent changes of NPP, τ, and Xp between 2050 and 2005 (i.e., average of 2046–2050 minus average of 2001–2005), respectively. NPP: net primary production, τ: C residence time, Xp: instantaneous C storage potential
