A study in Science says that tropical forests are now net sources of CO2: Here we use 12 years (2003 — 2014) of MODIS pantropical satellite data to quantify net annual changes in the aboveground carbon density of tropical woody live vegetation, providing direct, measurement - based evidence that the world's tropical forests are a net carbon source of 425.2 ± 92.0 Tg C yr — 1.

With respect to why there was a significant increase in tree density over the past several decades, Dolanc offers that the changes in the density and composition of lower - elevation forests are consistent with fire suppression; but that the density increases in high - elevation vegetation types (subalpine forests generally don't burn) are «more likely to be caused by changing climate.»

Estimating the carbon stocks in terrestrial ecosystems and accounting for changes in these stocks requires adequate information on land cover, carbon density in vegetation and soils, and the fate of carbon (burning, removals, decomposition).
