The terrestrial carbon sink has been large in recent decades, but its size and location remain uncertain. Using forest inventory data and long-term ecosystem carbon studies, we estimate a total forest sink of 2.4 +- 0.4 petagrams of carbon per year (Pg C/year) globally for 1990 to 2007. We also estimate a source of 1.3 +- 0.7 PG C/year from tropical land-use change, consisting of a gross tropical deforestation emission of 2.9 +- 0.5 Pg C/year partially compensated by a carbon sink in tropical forest regrowth of 1.6 +- 0.5 Pg C/year. Together, the fluxes comprise a net global forest sink of 1.1 +- 0.8 Pg C/year, with tropical estimates having the largest uncertainties. Our total forest sink estimate is equivalent in magnitude to the terrestrial sink deduced from fossil fuel emissions and land-use change sources minus ocean and atmospheric sinks.
