Climate change affects tropical forests through warming and increased occurrence of extreme events such as droughts and heatwaves, as well as more frequent fires, which increase tree mortality and reduce tree growth, limiting the ability of forests to regenerate . Climate change is altering the structure and species composition of tropical tree communities , including transitions from moist to drier forest in regions such as the Amazon , and movement of species from lower to higher elevations . Despite CO2 fertilisation, ongoing climate change has weakened the carbon sink potential of tropical forests in Amazonia and, to a lesser extent, in Africa and Asia .
