Amazon forest carbon sink closed by 2010 drought: Scientists
Q. Amazon forest spanning across Brazil, Peru, Columbia and other South American countries is the world’s ___________ forest.- Published on 08 Jul 16a. Largest
b. Second Largest
c. Third Largest
d. Fourth Largest
ANSWER: Largest
Amazon forest spanning across Brazil, Columbia, Peru and other South American countries is the world’s largest forest covering 5.5 million square kilometres.
- Scientists have estimated that the forest stores 100 bt of carbon in its biomass and changes can have global consequences
- This forest suffered a mjor drought in 2005, then 2010
- 2010 drought shut down the Amazon Basin carbon sink by destroying trees and slowing growth
- Amazon may be losing the capacity to take carbon from the atmosphere as a result of this
- This marks the first basin wide study of the impact of the 2010 drought and its interaction with previous droughts
- Using long term measurements from the RAINFOR network spanning close to 100 locations across the Amazon basin, the first and second drought were found to have temporarily lost biomass
