Global sea level rise (or sea level change) is influenced by a combination of melting water from glaciers and thermal expansion as sea water warms.
Sea levels are rising for two main reasons:
Thermal Expansion: Ocean temperatures are rising, and warmer water takes up more space than colder water.
More Water: Melting glaciers and ice sheets are adding more water to the ocean.
