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 ...
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 ...
Past sea level – Sea level variations over geological time scales; Holocene glacial retreat – Global deglaciation starting about 19,000 years ago and accelerating about 15,000 years ago; Holocene climatic optimum – Global warm period around 9,000–5,000 years ago; 8.2-kiloyear event – Rapid global cooling about 8,200 years ago

As of 2012 about 3.1% of Earth's surface and 10.7% of the land area is covered in year-round ice. ... 20,000 years ago and when the sea level was likely more than 110 ...
During the Late Holocene, the mangroves declined as sea level dropped and freshwater supply increased. [90] In the Santa Catarina region, the maximum sea level highstand was around 2.1 metres above present and occurred about 5,800 to 5,000 BP. [91] Sea levels at Rocas Atoll were likewise higher than present for much of the Late Holocene. [92]
The fossils were between 35.5 to 35.9 million years old and were found in a nearly 10-foot-long rock core: a tube-like sample taken from underneath the Gulf of Mexico by the scientific Deep Sea ...
Beringia sea levels (blues) and land elevations (browns) measured in metres from 21,000 years ago to present. Beringia is defined today as the land and maritime area bounded on the west by the Lena River in Russia; on the east by the Mackenzie River in Canada; on the north by 72° north latitude in the Chukchi Sea; and on the south by the tip of the Kamchatka Peninsula.
