This article doesn’t cover one of the key contributing factors to this which is the cyclical nature of drought resilience and deforestation. As rainforest is lost, precipitation decreases due to a decrease in tree perspiration, reducing humidity and the amount of water available to the trees, making them more susceptible to fires.
When you then combine that with longer dry seasons, higher max temperatures, and slash and burn land management practices, the rainforest is in for a bad time.
