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. By 8000 years ago the marshes were drowned by the sea, leaving no trace ...
The early Holocene sea level rise (EHSLR) was a significant jump in sea level by about 60 m (197 ft) during the early Holocene, between about 12,000 and 7,000 years ago, spanning the Eurasian Mesolithic. [1] The rapid rise in sea level and associated climate change, notably the 8.2 ka cooling event (8,200 years ago), and the loss of coastal ...
The Holocene (/ ˈhɒl.əsiːn, - oʊ -, ˈhoʊ.lə -, - loʊ -/) [2][3] is the current geological epoch, beginning approximately 11,700 years ago. [4] It follows the Last Glacial Period, which concluded with the Holocene glacial retreat. [4] The Holocene and the preceding Pleistocene [5] together form the Quaternary period.
Holocene climatic optimum. The Holocene Climate Optimum (HCO) was a warm period in the first half of the Holocene epoch, that occurred in the interval roughly 9,500 to 5,500 years BP, [1] with a thermal maximum around 8000 years BP. It has also been known by many other names, such as Altithermal, Climatic Optimum, Holocene Megathermal, Holocene ...
History. In 1997, William Ryan, Walter Pitman, Petko Dimitrov, and their colleagues first published the Black Sea deluge hypothesis. They proposed that a catastrophic inflow of Mediterranean seawater into the Black Sea freshwater lake occurred around 7,600 years ago, c. 5600 BCE. [3][4] As proposed, the Early Holocene Black Sea flood scenario ...
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. [3]: 1216 This was faster than the sea level had ever risen over at least the past 3,000 years. [3]: 1216 The rate accelerated to 4.62 mm (0.182 in)/yr for the decade 2013–2022. [4]
Doggerland. Coordinates: 52.°N 3°E. Map of Doggerland at its near maximum extent c. 10,000 years Before Present (~ 8000 BCE) (top left) and its subsequent disintegration by 7000 BP (~5000 BCE) Doggerland was an area of land in Northern Europe, now submerged beneath the southern North Sea. This region was repeatedly exposed at various times ...
About 30,000 years ago, sea levels began to fall, temperatures in the south-east of the continent dropped by as much as 9 degrees Celsius, and the interior of Australia became more arid. About 20,000 years ago, New Guinea and Tasmania were connected to the Australian continent, which was more than a quarter larger than today. [68]
