Amazon rainforest
Impact of early 21st-century Amazon droughts

In 2005, parts of the Amazon basin experienced the worst drought in one hundred years, and there were indications that 2006 may have been a second successive year of drought. A 2006 article in the UK newspaper The Independent reported the Woods Hole Research Center results, showing that the forest in its present form could survive only three years of drought. Scientists at the Brazilian National Institute of Amazonian Research argued in the article that this drought response, coupled with the effects of deforestation on regional climate, are pushing the rainforest towards a " tipping point " where it would irreversibly start to die. It concluded that the forest is on the brink of being turned into savanna or desert, with catastrophic consequences for the world's climate. A study published in Nature Communications in October 2020 found that about 40% of the Amazon rainforest is at risk of becoming a savanna-like ecosystem due to reduced rainfall. A study published in Nature climate change provided direct empirical evidence that more than three-quarters of the Amazon rainforest has been losing resilience since the early 2000s, risking dieback with profound implications for biodiversity, carbon storage and climate change at a global scale.
