What is the impact of rising sea levels on coastal ecosystems?

Rising sea levels have a significant impact on coastal ecosystems, primarily leading to habitat loss and increased erosion. As sea levels rise, saltwater intrudes into coastal habitats, which can lead to the loss of freshwater ecosystems and the displacement of species that rely on these areas for survival. Wetlands, mangroves, and tidal marshes are particularly vulnerable, as their ability to adapt to rising waters is often hindered.

Additionally, increased erosion occurs as higher water levels can exacerbate wave action and storm surges, further damaging coastal habitats. This erosion can lead to the loss of land and resources that are critical for both marine and terrestrial species, significantly altering the ecosystem dynamics. Thus, the effects of rising sea levels can disrupt existing habitats, decrease biodiversity, and present challenges for the species that inhabit these coastal regions.
