Marine ecosystems have a valuable role to play in mitigating the effects of climate change. That’s because such ecosystems – and, particularly, vegetated tidal ecosystems like mangroves and salt marshes – capture and store a significant amount of atmospheric carbon dioxide (CO₂). CO₂ has accumulated in Earth’s atmosphere at unprecedented levels since the industrial revolution. Scientific evidence shows this is the primary driver of climate change.
“Blue carbon”, the term used to describe CO₂ absorbed by marine ecosystems, was an important topic of discussion at last year’s COP27 talks in Egypt.
