In sharp contrast, the period between 14,300 and 11,100 years ago, which includes the Younger Dryas interval, was an interval of reduced sea level rise at about 6.0–9.9 mm/yr. Meltwater pulse 1C was centered at 8,000 years ago and produced a rise of 6.5 m in less than 140 years, such that sea levels 5000 years ago were around 3m lower than ...
Sea surface height change from 1992 to 2019: Blue regions are where sea level has gone down, and orange/red regions are where sea level has risen (the visualization is based on satellite data). [ 2 ] Between 1901 and 2018, the average sea level rose by 15–25 cm (6–10 in), with an increase of 2.3 mm (0.091 in) per year since the 1970s.
During deglaciation since the Last Glacial Maximum, between about 20,000 to 7,000 years ago (20–7 ka), the sea level rose by a total of about 100 m (328 ft), at times at extremely high rates, due to the rapid melting of the British-Irish Sea, Fennoscandian, Laurentide, Barents-Kara, Patagonian, Innuitian and parts of the Antarctic ice sheets ...
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 years ago, during which the global sea level rose between 16 meters (52 ft) and 25 meters (82 ft) in ...
Postglacial Sea level Rise Curve and Meltwater Pulses (MWP) Meltwater pulse 1B (MWP1b) is the name used by Quaternary geologists, paleoclimatologists, and oceanographers for a period of either rapid or just accelerated post-glacial sea level rise that some hypothesize to have occurred between 11,500 and 11,200 years ago at the beginning of the Holocene and after the end of the Younger Dryas.

Sea level change; Measurements by TOPEX/Poseidon and Jason-1 show that mean sea level has been rising by about 3 mm (0.12 inches) a year since 1993. This is about twice the estimates from tide gauges for the previous century, indicating a possible recent acceleration in the rate of sea level rise.
Post-glacial sea level rise decelerates, slowing submersion of landmasses taking place over previous 10,000 years. Possible identical ancestors point : time of latest subgroup of human population comprising all those that are ancestors of all present-day humans, while all other people of the time have no present-day descendants.
The sea-level equation (SLE) is a linear integral equation that describes the sea-level variations associated with the PGR. The basic idea of the SLE dates back to 1888, when Woodward published his pioneering work on the form and position of mean sea level , [ 45 ] and only later has been refined by Platzman [ 46 ] and Farrell [ 47 ] in the ...
