NASA's map shows carbon storage in tropical forests in 75m countries, and the level of certainty (Image: NASA)
A NASA-led research team has created a new map using ground and satellite data that accurately quantifies the amount and location of carbon stored in Earth's tropical trees and forests. Based on data from the early 2000s, the map focuses on 2.5 million hectares of tropical forest in seventy-five countries. Data shows that tropical forests contain 247 billion tons of carbon, and of this carbon stock, almost half is held in Latin American forests. Almost the same carbon stock is stored in sub-Saharan Africa in its entirety, compared with 61 billion tons of carbon stored in Brazilian forests alone.
