Sea levels have been comparatively stable over the past 6,500 years, ending with a 0.50 m sea level rise over the past 1,500 years. For example, about 10,200 years ago the last land bridge between mainland Europe and Great Britain was submerged, leaving behind a salt marsh.
It shows sea level rise in 2100 of about 44 cm (17 in) with a range of 28–61 cm (11–24 in). The "moderate" scenario, where CO 2emissions take a decade or two to peak and its atmospheric concentration does not plateau until the 2070s is called RCP 4.5. Its likely range of sea level rise is 36–71 cm (14–28 in).
This marker indicating sea level is situated between Jerusalem and the Dead Sea. 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. The global MSL is a type of vertical datum – a standardised geodetic datum ...
The Atlantic meridional overturning circulation (AMOC) is the main current system in the Atlantic Ocean, [ 1 ]: 2238 and is also part of the global thermohaline circulation, which connects the world's oceans with a single "conveyor belt" of continuous water exchange. [ 29 ] Normally, relatively warm, less-saline water stays on the ocean's ...

Image showing sea level change during the end of the last glacial period. Meltwater pulse 1A is indicated. Meltwater pulse 1A (MWP1a) is the name used by Quaternary geologists, paleoclimatologists, and oceanographers for a period of rapid post-glacial sea level rise, between 13,500 and 14,700 calendar years ago, during which the global sea level rose between 16 meters (52 ft) and 25 meters (82 ...
The Zanclean flood or Zanclean deluge is theorized to have refilled the Mediterranean Sea 5.33 million years ago. [ 1 ] This flooding ended the Messinian salinity crisis and reconnected the Mediterranean Sea to the Atlantic Ocean, although it is possible that even before the flood there were partial connections to the Atlantic Ocean.

Western Interior Seaway. The Western Interior Seaway (also called the Cretaceous Seaway, the Niobraran Sea, the North American Inland Sea, and the Western Interior Sea) was a large inland sea that split the continent of North America into two landmasses for 34 million years. The ancient sea, which existed from the early Late Cretaceous (100 Ma ...
