Mangrove forests are one of the most important weapons in the fight against climate change. Not only do they directly store huge amounts of carbon, but they actively capture additional carbon dioxide from the atmosphere and sequester it in their soils. When mangroves are destroyed, huge quantities of carbon are released into the atmosphere, significantly contributing to greenhouse gas emissions. Yet, until recently, little research has been done to identify which mangrove forests store the most carbon and are therefore most important in combatting climate change. However, all this has changed, thanks to a new study showcasing a global map of carbon storage in mangrove forests.
