Tropical forests store enormous amounts of carbon and harbor most of the world's terrestrial biodiversity, but scientists have expressed concern that increasingly severe droughts could threaten the forests' ability to survive and continue absorbing carbon from the atmosphere.

A study published in Nature suggests tropical trees may be more adaptable to drought than previously believed. The research offers unexpected hope for the ability of tropical forests to weather changing climate conditions.
