Climate Change can Alter Methane Emission and Uptake in the Amazon

Extreme temperatures and humidity levels (excessive rain or drought) projected for the Amazon in the context of climate change may increase the volume of methane-producing microorganisms in flooded areas and reduce potential uptake of this greenhouse gas in upland forests by 70%, with global impacts, according to a study conducted by researchers at the University of São Paulo (USP) in Brazil. An article reporting their findings is published in the journal Environmental Microbiome.
