Abstract The terrestrial carbon sink has been large in recent decades, but its size and location remain uncertain. Using<br />

forest inventory data and long-term ecosystem carbon studies, we estimate a total forest sink of 2.4 ± 0.4<br />

petagrams of carbon per year (Pg C year⁻¹) globally for 1990 to 2007. We also estimate a source of 1.3 ± 0.7 Pg<br />

C year⁻¹ from tropical land-use change, consisting of a gross tropical deforestation emission of 2.9 ± 0.5 Pg C<br />

year⁻¹ partially compensated by a carbon sink in tropical forest regrowth of 1.6 ± 0.5 Pg C year⁻¹. Together, the<br />

fluxes comprise a net global forest sink of 1.1 ± 0.8 Pg C year⁻¹, with tropical estimates having the largest<br />

uncertainties. Our total forest sink estimate is equivalent in magnitude to the terrestrial sink deduced from fossil<br />

fuel emissions and land-use change sources minus ocean and atmospheric sinks.<br />
