The authors suggest that recurrent 21st century droughts may undermine achievements in reducing emissions from deforestation in this region. Lead author…
The most extensive land-based study of the effect of drought on Amazonian rainforests to date has shown that a recent drought completely shut down the Amazon Basin’s carbon sink. Previous research has suggested that the Amazon – the most extensive tropical forest on Earth – may be gradually losing its capacity to take carbon from…
