The Amazon rainforest is facing a barrage of pressures that might tip it into large-scale ecosystem collapse as soon as 2050, according to new research Wednesday warning of dire consequences for the region and the world.
They then analyzed these stressors – including global warming, annual rainfall, the length of the dry season and deforestation – to see how these might act individually or together to cause feedback loops that could trigger a major collapse. "We have evidence showing that rising temperatures, extreme droughts and fires can affect how the forest functions and change which tree species can integrate the forest system," said co-author Adriane Esquivel-Muelbert from Britain's Birmingham Institute of Forest Research.Flores said the severe drought foreshadows the climatic conditions expected for the region in the early 2030s.
