The Amazon basin spans over 6 million square kilometers, and is home to one-fifth of the worlds land species. In addition, it supports the 30 million people who live and depend on the land as a source of food, medicine, and shelter. Thats not even including the key role it plays in regulating the regional AND global climate.

Trees absorb water through their roots and transport it to their leaves, where its released as vapor through small pores in a process called transpiration. As the water vapor rises and condenses, it forms rain clouds over the forest canopy. Basically, the rainforest is making its own weather. For example, one large tree can release 1,000 liters of water into the atmosphere in a single day.

The rainforest recycles this water up to six times before it moves out of the region, but as more trees are cut down, those that remain may not be able to recycle enough water to survive. Less trees means more sunlight will hit the forest floor, exposing the forest to higher temperatures. Since deforestation began accelerating in the 1970s, 800,000 square kilometers of the Amazon have been lost. And over that same period, the average temperature of the basin has risen by 1 degree Celsius.

Amazon near tipping point of switching from rainforest to savannah study

"New research shows that this tipping point could be much closer than previously thought. As much as 40% of the existing Amazon rainforest is now at a point where it could exist as a savannah instead of as rainforest, according to a study published in the journal Nature Communications."

"Since the 1970s nearly 800,000km of Brazils original 4m km of Amazon forest has been lost to logging, farming, mining, roads, dams and other forms of developmentan area equivalent to that of Turkey, and bigger than that of Texas."

"Evidence that irreversible changes in Earths climate systems are underway means we are in a state of planetary emergency, leading climate scientists warn. A cascade of tipping points could amount to a global tipping point, where multiple earth systems march past the point of no return, they say."
