Rising seas could drown mangroves and release vast stores of carbon

Mangroves are famous for trapping vast amounts of carbon, helping slow climate change. However, a new study suggests rising sea levels could eventually reduce that benefit across entire forests. As flooding becomes too extreme, mangroves may die off and their carbon-rich soils could erode, potentially turning these coastal ecosystems from carbon sinks into carbon sources.
