Climate change, deforestation turned Amazon forest into major CO2 emitter
FirstpostIf Amazonia — with 450 billion tonnes of CO2 locked in its trees and soil — were to become a consistent source, tackling the crisis would be more challenging. Climate change and deforestation have flipped a large swathe of the Amazon basin from absorbing to emitting planet-warming CO2, a transformation that could turn humanity’s greatest natural ally in the fight against global warming into a foe, researchers reported on Wednesday. If Amazonia – with 450 billion tonnes of CO2 locked in its trees and soil – were to become a consistent source rather than a “sink” of CO2, tackling the climate crisis would be vastly more challenging. Another recent study, using a different methodology, found that the Brazilian Amazon released nearly 20 percent more CO2 over the last decade than it absorbed from 2010 to 2019.
