We also confirm mechanisms of the Amazon dieback in terms of climate drivers, ecological processes and land-use change effects

We look at CMIP5 and CMIP6 Earth System models under high-emission scenarios that have extensions up to 23rd century - 9 out of 12 models project localized to large-scale rainforest dieback that starts already within the 21st century

Our new study in @commsearth.nature.com shows that Amazon dieback could begin within the 21st century in the absence of climate change mitigation

The latter combined effect (cross-term) has the most complex representation, where changes in CO2 concentrations and temperatures interact to influence carbon sinks. See the comparison of gamma+cross term effects on land & ocean

Our new study in #ESD explores impacts of CO2 and non-CO2 GHG concentration decrease on the climate and carbon cycle
