Much of the world’s natural coastline is protected by living habitats, most notably mangroves in warmer waters and tidal marshes closer to the poles. These ecosystems support fisheries and wildlife, absorb the impact of crashing waves and clean up pollutants. But these vital services are threatened by global warming and rising sea levels.
Recent research has shown wetlands can respond to sea level rise by building up their root systems, pulling carbon dioxide from the atmosphere in the process. Growing recognition of the potential for this “blue” carbon sequestration is driving mangrove and tidal marsh restoration projects.
