Figure 1-1: The global carbon cycle, showing
the carbon stocks in reservoirs (in Gt C = 1015 g C) and carbon flows
(in Gt C yr
-1) relevant to the anthropogenic perturbation as annual
averages over the decade from 1989 to 1998 (Schimel
et al., 1996,
Tables 2.1 and
2.2).
Net ocean uptake of the anthropogenic perturbation equals the net air-sea
input plus runoff minus sedimentation (discussed by Sarmiento and Sundquist,
1992).
