“…However, the partitioning of this land-atmosphere flux to effects from humaninduced land-use and land-cover change (LULCC) and the transient change in the residual terrestrial sink remains highly debated (Schimel et al, 2015). It is estimated that approximately a third of the cumulative anthropogenic CO 2 emissions in the industrial period stem from the effects of LULCC (Arneth et al, 2017;Brovkin et al, 2013;Houghton and Nassikas, 2017;McGuire et al, 2001;Mahowald et al, 2017;Pongratz and Caldeira, 2012;Sitch et al, 2015;Strassmann et al, 2008;Stocker et al, 2017Stocker et al, , 2014Peng et al, 2017). A better understanding of the mechanisms of the historical terrestrial carbon cycle is vital for more accurate future projections of the global carbon cycle and climate.…”
