In a pristine corner of the Amazon, scientists have spent more than two decades simulating drought to understand how the rainforest might respond to a drier future. Understanding how soil, roots and trees respond is critical to predicting the Amazon’s future. (AP Video by Lucas Dumphreys. Produced by Julián Trejo Bax)
