Scientists warned on Wednesday, in a study, that a combination of drought, heat, and other factors, including climate change, could collapse South America’s Amazon rainforest system. They revealed that nearly half of the Amazon could reach a tipping point by 2050.
“The region is increasingly exposed to unprecedented stress from warming temperatures, extreme droughts, deforestation and fires, even in central and remote parts of the system,” the researchers wrote in the study published in the journal Nature.
Ecologist Bernardo Flores of the University of Santa Catarina in Brazil, lead author of the report, “Once we cross this tipping point, maybe we cannot do anything anymore.”
“The forest will die by itself.”
The study is the latest effort to determine if and when the rainforest ecosystem might change significantly.
This could be catastrophic as the Amazon is crucial in absorbing large amounts of climate-warming carbon dioxide from the atmosphere.
