The significance of studying sea-level rise due to climate change lies in understanding its impacts on coastal ecosystems and human settlements. Rising sea levels threaten habitats like wetlands and mangroves, which serve as critical buffers against storms and erosion. Moreover, they endanger freshwater supplies and increase the salinity of coastal regions, affecting agriculture and drinking water sources. Understanding these changes is essential for developing adaptive strategies to mitigate risks and protect both the environment and vulnerable communities.
