The capacity of oceans to mitigate climate change has drawn significant focus toward blue carbon and ocean-based climate solutions. Coastal ecosystems such as mangroves, salt marshes, and seagrasses capture and store carbon at rates far surpassing terrestrial forests, making them crucial allies in reducing greenhouse gas emissions. Research on blue carbon and ocean-based climate solutions highlights innovative strategies like ecosystem restoration, carbon credit markets, and nature-based adaptation measures to enhance resilience against climate impacts. Integrating these approaches with global climate policies can offer sustainable pathways for both mitigation and adaptation. Scientists, policymakers, and local communities are working together to scale up initiatives that restore degraded habitats, monitor carbon sequestration capacity, and link conservation with socioeconomic benefits. These efforts not only combat climate change but also strengthen coastal resilience, protect biodiversity, and support sustainable livelihoods.
