Impact of deforestation and climate on the Amazon Basin's above-ground biomass during 1993-2012.

ABSTRACT: Since the 1960s, large-scale deforestation in the Amazon Basin has contributed to rising global CO₂ concentrations and to climate change. Recent advances in satellite observations enable estimates of gross losses of above-ground biomass (AGB) stocks due to deforestation. However, because of simultaneous regrowth, the net contribution of deforestation emissions to rising atmospheric CO₂ concentrations is poorly quantified. Climate change may also reduce the potential for forest regeneration in previously disturbed regions. Here, we address these points of uncertainty with a machine-learning approach that combines satellite observations of AGB with climate data across the Amazon Basin to reconstruct annual maps of potential AGB during 1993-2012, the above-ground C stora
