A.  aPantropical tree rings show small effects of drought on stem growth.h[electronic resource]  c2025  aIncreasing drought pressure under anthropogenic climate change may jeopardize the potential of tropical forests to capture carbon in woody biomass and act as a long-term carbon dioxide sink. To evaluate this risk, we assessed drought impacts in 483 tree-ring chronologies from across the tropics and found an overall modest stem growth decline (2.5% with a 95% confidence interval of 2.2 to 2.7%) during the 10% driest years since 1930. Stem growth declines exceeded 10% in 25% of cases and were larger at hotter and drier sites and for gymnosperms compared with angiosperms. Growth declines generally did not outlast drought years and were partially mitigated by growth stimulation in wet years. Thus, pantropical forest carbon sequestration through stem growth has hitherto shown drought resilience that may, however, diminish under future climate change.  aBiomass  aCarbon cycle  aClimate change  aForest growth  aBiomassa  aCarbono  aCrescimento  aFloresta Tropical  aMudança Climática  aTropical forest1 aGROENENDIJK, P.1 aRAHMAN, M.1 aTROUET, V.1 aABIYU, A.1 aACUÑA-SOTO, R.1 aADENESKY-FILHO, E.1 aALFARO-SÁNCHEZ, R.1 aANHOLETTO, C.
