A recent drought shut down the Amazon Basin's carbon sink by killing trees and slowing trees' growth rates, a study has shown.
The term carbon sink refers to the ability of a natural zone to absorb CO2 from the atmosphere.
In

showed trees' mortality rate went up while growth rates declined. The
findings have been published by the Global Biogeochemical Cycles journal.
