From mongabay: The Brazilian Amazon is now a net CO2 source, study: The Brazilian Amazon has been transformed from a carbon dioxide sink to a source for new emissions over the past two decades, a new study shows. While the Amazon as a whole, which straddles nine countries, has absorbed about 1.7 billion metric tons of CO2 equivalent more than it has emitted in the past 20 years, the Brazilian portion alone has emitted a net 3.6 billion metric tons during that period. This study by the Monitoring of the Andean Amazon Project (MAAP) is unique because it was able to go deeper in analyzing changes in forest emissions from different parts of the rainforest compared to previous research, says author Matt Finer. Satellite monitoring data show that formally protected areas and lands controlled by Indigenous peoples hold the best hope for preserving the Amazon and its function as a bulwark against climate change.
