The increased variability in sea levels poses risks to coastal ecosystems, including salt marshes, rocky shores, and tidal wetlands. These areas are critical habitats for diverse species and play a role in carbon sequestration. Changes in sea-level patterns could lead to coastal squeeze, where ecosystems are trapped between rising seas and human infrastructure, reducing their ability to adapt. Biodiversity loss and altered food webs are potential outcomes, with cascading effects on marine and terrestrial ecosystems. Communities dependent on these ecosystems for livelihoods may also face economic challenges.
