Global tropical forest carbon map
New global carbon map for 2.5 billion ha of forests
(05/31/2011) Tropical forests across Latin America, Africa, and Southeast Asia stored 247 gigatons of carbon — more than 30 years’ worth of current emissions from fossil fuels use — in the early 2000s, according to a comprehensive assessment of the world’s carbon stocks. The research, published in the journal Proceedings of the National Academy of Sciences by an international team of scientists, used data from 4,079 plot sites around the world and satellite-based measurements to estimate that forests store 193 billion tons of carbon in their vegetation and 54 billion tons in their roots structure. The study has produced a carbon map for 2.5 billion ha (6.2 billion acres) of forests.
