over two-thirds of deforestation from 1990 to 2005 . Four sites in the Amazon also showed net carbon emissions in the period 2010-2018, from deforestation and fire . In the Amazon, deforestation emitted 0.17 + 0.05 GtC yr1 from 2001 to 2015  while fires emitted 0.12 + 0.14 GtC yr1 from 2003 to 2015 . An analysis of the Amazon carbon loss from deforestation and degradation estimated a loss of 0.5 Gt yr1 in the period 2010 -2019, with degradation accounting for three-quarters . Intact old-growth Amazon rainforest has been a net carbon sink from 2000 to 2010   but may have become a net carbon source in 2010-2019  . These factors combined-recent impacts of climate change on undisturbed forest, coupled with deforestation and agricultural expansion, along with associated intentional burning-have caused Amazon rainforest to become an overall net carbon emitter .
