    Sea levels change when the volumes of the Earth's oceans change. It is not easy to measure the volume of the ocean, so scientists talk about surface level of the oceans when they describe sea level. However, the surface level of the ocean changes all the time due to tides, wind, and other factors.

    • Under conditions of global warming, sea levels are expected to rise for two main reasons: 1. In general, when liquids warm, they tend to expand. Therefore, if the oceans warm up, their volume should also increase, leading to a rise in the global sea level. 2. If global warming causes glaciers or ice sheets (i.e., ice on land) to melt, then the meltwater should increase the ocean volume. No…

      As the planet gets warmer, sea level rises for two reasons. First, warmer temperatures cause ice on land like glaciers and ice sheets to melt, and the meltwater flows into the ocean to increase sea level. Second, warm water expands and takes up more space than colder water, increasing the volume of water in the sea.

      As sea levels submerge coastal cities, precious water sources could become contaminated with saltwater and other contaminants let loose by destroyed infrastructure, similar to what happened in Fukushima, Japan, when a nuclear reactor was destroyed by an earthquake and tsunami.
