Mangroves Stage a Global Comeback, Shielding Coasts and Climate

Satellite data show the world’s mangrove forests are expanding since 2010 after decades of loss, with islands in Myanmar, Indonesia and Australia contributing to net gains. Mangroves store roughly four times more carbon than other forests and help buffer coastlines from flooding, erosion and storms. While regional degradation from harvesting and pollution persists, the overall rebound is a positive development for climate and coastal resilience, underscoring the need for continued protections, restoration, and monitoring.
