Te second major contributor to rising sea levels is thee melting of land- based ice, including glacier, ice caps, and the massive ice sheets of Greenland and Antarktyka. Unlike sea ice, which already displaces its equicent volume of water, land- based ice adds new water to the oceans whein it melts.

Mangroves have demonstrante some capacity to declared to sea level rise acculating sediment and organic matter, which raites the soil surface and allows the present to maintain its position relative to sea level.
