![]() ![]() Melting land ice, however, contributes to about one third of sea level rise. Melting sea ice, much like ice cubes melting in a drink, does not affect the level of the oceans. At both locations, we have ice on land (“land ice”) and ice floating in the ocean (“sea ice”). Melting polar ice caps - Think of our north and south polar regions.As glaciers melt, the runoff flows into the oceans, raising their levels. Melting mountain glaciers - Glaciers are bodies of ice on land that are constantly moving, carving paths through mountains and rock.But before we get into that, let’s understand the main contributors to sea level rise: In fact, in some areas, such as the west coast of the US, sea level has actually dropped slightly … for now.
