Detailed explanation-3: -For decades, deforestation, drought, fires, and climate change have ravaged the Amazon, worrying scientists that the sprawling South American rainforest could eventually hit a critical tipping point and irreversibly transition into a drier, savanna-like ecosystem.

Detailed explanation-4: -Despite large uncertainty in most regions we find that some forests are consistently at higher risk, including southern boreal forests and those in western North America and parts of the Amazon.

Detailed explanation-5: -Savannas can result from either climate, soil conditions, animal behavior, or agricultural practices, which limit the occurrence of trees. Humans create savannas by burning the grasslands and felling the trees in order to plant crops.
