A new study suggests that the tropical forests of the Amazon rainforest are emitting more carbon dioxide than they absorb. This is due to factors such as deforestation and climate change, which are causing increased tree mortality. The study used satellite data and found that the Amazon forests are now a net source of CO2 emissions, contributing to climate change. This has significant implications for global efforts to reduce carbon emissions and mitigate the impacts of climate change. The findings emphasize the urgent need for conservation and restoration efforts in the Amazon rainforest.
