Around two-thirds of the Amazon rainforest could shift into degraded forest or savanna-like ecosystems at 1.5–1.9°C of global warming if deforestation increases to roughly 22–28% of the Amazon, according to a new study from the Potsdam Institute for Climate Impact Research (PIK) published in Nature. Without additional deforestation, by contrast, such large-scale changes would likely occur only at much higher warming levels of around 3.7–4°C.
