Mean sea level ( MSL, often shortened to sea level) is an average surface level of one or more among Earth 's coastal bodies of water from which heights such as elevation may be measured.
Sea level rise is caused primarily by two factors related to global warming: the added water from melting ice sheets and glaciers, and the expansion of seawater as it warms. The first graph tracks the change in global sea level since 1993, as observed by satellites.
19 de oct. de 2023 · Learn about sea level, the base level for measuring elevation and depth on Earth. Find out how sea level varies with climate, glaciers, and land movement, and how it is measured using the Metonic cycle and local mean sea level. Discover the highest and lowest places on Earth, and the effects of sea-level rise on low-lying areas.
