Method "Here, [researchers] present bottom-up estimates of C stocks and fluxes for the world’s forests based on recent inventory data and long-term field observations coupled to statistical or process models (table S1). [They] advanced [their] analyses by including comprehensive C pools of the forest sector (dead wood, harvested wood products, living biomass, litter, and soil) and report past trends and changes in C stocks across countries, regions, and continents representing boreal, temperate, and tropical forests (refs 5, 6)."
Comments "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, [researchers] estimate a total forest sink of 2.4±0.4 petagrams [10^15 grams] of carbon per year (Pg C/year) globally for 1990 to 2007."
