The Amazon forest carbon sink is declining, mainly as a result of land-use and climate change. Here we investigate how changes in law enforcement of environmental protection policies may have affected the Amazonian carbon balance between 2010 and 2018 compared with 2019 and 2020, based on atmospheric CO vertical profiles, deforestation and fire data, as well as infraction notices related to illegal deforestation. We estimate that Amazonia carbon emissions increased from a mean of 0.

- Amazonia contains the world's largest tropical forests and has been a significant carbon sink, but this is declining due to deforestation and climate change.
- Researchers conducted 590 aircraft measurements from 2010 to 2018, finding that carbon emissions are higher in eastern Amazonia, largely due to fire emissions.
- Eastern Amazonia, especially the southeast, is becoming a net carbon source due to intensified deforestation and climate stress, leading to increased tree mortality and decreased photosynthesis.
