Figure 2.

Major pools and fluxes of the global carbon cycle, with red color indicating anthropogenic fluxes for 2000–2006 and cumulative pools for 1800–2006 based on [40,41], with updates from [2]. About 1/3 (20 GtC y-1) of the net terrestrial productivity is wood production, a substantial fraction of which is the target of a sustainable carbon sink via wood burial.
