Editorial statement
The Amazon rainforest plays a crucial role in global carbon storage, and even a minor destabilization could result in considerable carbon loss. This study uses a process-based model to show that elevated CO2 concentrations have multiple and sometimes contrasting effects on the Amazon forest's carbon dynamics and vulnerability. The study thus provides valuable insights into the rainforest’s evolution in the context of more frequent and intense future climate extremes.

Short summary
Elevated CO2 concentration (eCO2) is critical for shaping the future path of forest carbon uptake, while uncertainties remain about concurrent carbon loss. Here, we found that eCO2 might amplify competition-induced carbon loss, while the extent of drought-induced carbon loss hinges on the balance between heightened biomass density and water-saving benefits. This is the first time that such carbon loss responses to ongoing climate change have been quantified separately over the Amazon rainforest.
