Fig. 1From: Country-level land carbon sink and its causing components by the middle of the twenty-first centuryValidation of land carbon sink (∆X) calculations with the transient traceability framework. Derived ∆X is calculated by Eq. 9 and direct ∆X is the difference in carbon storage between the average of 2046–2050 and the average of 2001–2005 calculated directly from CMIP5 model outputsBack to article page
