Deforestation’s impact on climate is less severe than other types of Amazon degradation, new study finds

A study published on Monday in Proceedings of the National Academy of Sciences shows that logging, forest burning, and other human activities, along with natural disturbances, are releasing more carbon dioxide and warming the climate more than clear-cut deforestation.

Brazil’s President Luiz Inácio Lula da Silva, who took office in 2023, vowed to address Amazon deforestation and reestablish Brazil as a climate leader after significant damage during Jair Bolsonaro’s presidency.?

However, a recent study reveals that deforestation itself is only a small part of the broader climate damage affecting the Amazon.

The study, which employed airborne laser scanning to assess Amazon rainforest changes more accurately than satellite imagery, found that human-caused degradation and natural disturbances account for 83% of carbon emissions, while deforestation accounts for just 17%.?

The research highlights the severe damage from fires exacerbated by drought, turning the region into a fire-prone area.
