             abstract = "The semi-arid region of Northeast Brazil (NEB) experiences severe 
                         droughts during El Niņo Southern Oscillation (ENSO) years, with 
                         major impacts on the dynamics of the native vegetation (Caatinga). 
                         However, the effect of these droughts on carbon cycling is not 
                         well understood. Here, a numerical model is used to investigate 
                         the influence of variations in Pacific and Atlantic sea surface 
                         temperatures (SST) on drought and carbon dynamics of the Caatinga 
                         during past ENSO events. We demonstrate that precipitation 
                         reductions in the Caatinga have a strong influence on vegetation 
                         dynamics, with net primary production (NPP) remaining low 
                         throughout the droughts. Furthermore, the Caatinga acts as a 
                         carbon sink, even in years of severe drought. However, net 
                         ecosystem exchange (NEE) is lower in years of low NPP rates, 
                         resulting in long periods with limited ecosystem activity. The SST 
                         patterns indicate that extreme vegetation changes in the Caatinga 
                         are associated with the combination of ENSO events and North 
                         Atlantic SST warming.",
