Aperture

Aerial view of the round structures of the AmazonFACE experiment built in a National Institute of Amazonian Research (INPA) research area, located 80 km north of Manaus. AmazonFACE is one of the largest scientific experiments ever conducted in the Amazon. It simulates, in a tropical forest area, the impact of the increase in atmospheric CO2 predicted for the coming decades. Using FACE (Free Air CO2 Enrichment) technology, the project seeks to understand how climate change will affect the forest, its biodiversity, and the beneficial functions it currently carries out.

Testing the Amazon's ability to soak up increasing carbon emissions

Deep in the Amazon rainforest, an unusual experiment is deliberately pumping out greenhouse gas to measure how flora and fauna react to the levels we expect to reach in the future. Photographer Lalo de Almeida captures the vast machinery of the AmazonFACE project
