What is the difference between local sea level and mean sea level?
Height above mean sea level is a measure of a location's vertical distance (height, elevation or altitude) in reference to a vertical datum based on a historic mean sea level. In geodesy, it is formalized as orthometric height. The zero level varies in different countries due to different reference points and historic measurement periods.
Geopotential height – Type of altitude above mean sea level; Height above average terrain – Height based on large area surrounding object; often used in U.S. for antenna towers; List of places on land with elevations below sea level; Meltwater pulse 1A – Period of rapid post-glacial sea level rise
What is global mean sea level? This is the average height of the entire ocean surface. Global mean sea level rise is caused primarily by two factors related to global warming: the added water from melting land-based ice sheets and glaciers and the expansion of seawater as it warms.
May 3, 2018 · Some scientists, for example, hypothesize that for every increase of 33.8° Fahrenheit, the oceans will rise by approximately 7.54 feet. Yet another group of researchers predicts that the mean sea level will increase by 10 feet over the next 50 years.

Aug 10, 2017 · Sea level is a measure of the average height of the surface of the sea. Like land, the surface of the ocean is not flat or uniform. But unlike land – for the most part – it can change in short order.
Jul 8, 2019 · During the biggest Pleistocene glaciations about 20,000 years ago, mean sea level was about 400 feet (120 meters) lower than mean sea level today. If all of the Earth's ice sheets and glaciers were to melt, sea level could be up to 265 feet (80 meters) above current mean sea level.
