O Efeito Dominó da Amazônia

The report warns that the Amazon is nearing a tipping point where deforestation disrupts the water cycle, causing a 'domino effect' of degradation. CPI/PUC-Rio modeling shows that for every 100 trees deforested, 22 more die in distant areas due to water loss. If deforestation reaches 40%, the forest could lose 60% of its vegetation density and face climate collapse.

• The Amazon rainforest is approaching a tipping point where the loss of its 400 billion trees would release carbon emissions equivalent to five years of global emissions, making it impossible to limit global warming to 1.5°C.
• Research by CPI/PUC-Rio using a vegetation-climate model indicates a 'domino effect' where deforestation causes water scarcity in other areas; on average, for every 100 trees deforested, an additional 22 trees die in distant areas due to lack of water.
• The Amazon has already lost nearly 20% of its original area to deforestation, and at least another 20% has been impacted by degradation, reducing its capacity for carbon sequestration and storage.
• Forest degradation was responsible for nearly 70% of global carbon emissions from tropical forests between 2003 and 2014, while deforestation accounted for the remaining 30%.
• The report presents two 30-year scenarios: in Scenario A, if deforestation is stopped at the current 20% level, an additional 13% of the forest will be degraded. In Scenario B, if deforestation reaches 40%, an additional 20% will be degraded, leading to a loss of approximately 60% of vegetation density and climate collapse.
