BRAZIL - The Amazon is home to the world’s largest tropical rainforest and is often called the "lungs of the Earth." But a new study shows portions of the rainforest are now emitting more carbon dioxide than they absorb and the carbon sink is in decline due in part to deforestation and climate change.
In the study, published in the journal Nature on Wednesday, researchers investigated the Amazon’s carbon budget and the main drivers responsible for its change.Researchers performed 590 aircraft measurements of lower-atmosphere concentrations of carbon dioxide and carbon monoxide at four Amazonian sites between 2010 and 2018."Southeastern Amazonia, in particular, acts as a net carbon source to the atmosphere," the study authors wrote.
