The role of the world's forests as a "sink" for atmospheric carbon dioxide is the subject of active debate. Long-term monitoring of plots in mature humid tropical forests concentrated in South America revealed that biomass gain by tree growth exceeded losses from tree death in 38 of 50 Neotropical sites. These forest plots have accumulated 0.71 ton, plus or minus 0.34 ton, of carbon per hectare per year in recent decades. The data suggest that Neotropical forests may be a significant carbon sink, reducing the rate of increase in atmospheric carbon dioxide.
世界森林作为大气二氧化碳“汇”的作用是一个活跃的辩论话题。对南美洲成熟湿润热带森林中的样地进行的长期监测表明，在新热带地区的50个地点中，有38个地点树木生长带来的生物量增加超过了树木死亡造成的损失。近几十年来，这些森林样地每年每公顷积累了0.71吨（正负0.34吨）碳。数据表明，新热带森林可能是一个重要的碳汇，降低了大气中二氧化碳的增加速度。
