Amazon Rainforests More Resilient in Drought Than Supposed

The Amazon rain forest is not peculiarly susceptible to drought, and claims by the Intergovernmental Panel on Climate Change and the World Wildlife Fund that “up to 40% of the Amazonian forests could react drastically and be replaced by savannas from even a slight reduction in rainfall” are not borne out by the evidence. But similarly, neither is a competing claim “that these forests actually thrive from drought because of more sunshine under cloudless skies typical of drought condition.” Instead, the truth is that, while they may not flourish in times of reduced rainfall, “these forests may be more tolerant of droughts than we previously thought.” So concludes a new NASA-funded study appearing in the journal Geophysical Research Letters.
