Brazilian analysts are pumping CO2 into the Amazon rainforest canopy…. but it’s all in the name of science.⁣ ⁣ Suspended by crane, INPA researchers expose mature trees to 50% more CO2 than current atmospheric levels, simulating future climate conditions.⁣ ⁣ The ‘time machine’ experiment will enable monitoring of individual trees and their responses to stress.⁣ ⁣ Findings from the AmazonFACE site will help predict how much CO2 humans can emit while keeping global warming below two degrees.⁣ ⁣ #amazon #climate #rainforest #climatechange
