abstract = "Reduced rainfall increases the risk of forest dieback, while in
return forest loss might intensify regional droughts. The
consequences of this vegetation-atmosphere feedback for the
stability of the Amazon forest are still unclear. Here we show
that the risk of self-amplified Amazon forest loss increases
nonlinearly with dry-season intensification. We apply a novel
complex-network approach, in which Amazon forest patches are
linked by observation-based atmospheric water fluxes. Our results
suggest that the risk of self-amplified forest loss is reduced
with increasing heterogeneity in the response of forest patches to
reduced rainfall. Under dry-season Amazonian rainfall reductions,
comparable to Last Glacial Maximum conditions, additional forest
loss due to self-amplified effects occurs in 10-13% of the Amazon
basin. Although our findings do not indicate that the projected
rainfall changes for the end of the twenty-first century will lead
to complete Amazon dieback, they suggest that frequent extreme
drought events have the potential to destabilize large parts of
the Amazon forest.",
