GoKawiilAmazon FACE experiment nears launch to test forest's CO2 response
Researchers led by climatologist David Lapola of Brazil's State University of Campinas have built six ring-shaped towers rising above the canopy 80 kilometres north of Manaus for the AmazonFACE project. The decade-long experiment will expose sections of rainforest to elevated carbon dioxide levels to observe how trees and the surrounding ecosystem respond.
