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.
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 ...
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.

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 ...
Recent evidence indicates that humans processed (gathered) and consumed wild cereal grains as far back as 23,000 years ago. [1] c. 20,000 BC: Antarctica sees a very rapid and abrupt 6 °C increase in temperatures [2] c. 19,000 BC: Last Glacial Maximum/sea-level minimum: c. 20,000 BC c. 12,150 BC Mesolithic 1 period c. 17,000 BC c. 13,000 BC
8000 BC – 6000 BC: The post-glacial sea level rise decelerates, slowing the submersion of landmasses that had taken place over the previous 10,000 years. 8000 BC – 3000 BC: Identical ancestors point : sometime in this period lived the latest subgroup of human population consisting of those that were all common ancestors of all present day ...
