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 ...
At the onset of deglaciation about 19,000 years ago, a brief, at most 500-year long, glacio-eustatic event may have contributed as much as 10 m (33 ft) to sea level with an average rate of about 20 mm (0.8 in)/yr. During the rest of the early Holocene, the rate of sea level rise varied from a low of about 6.0–9.9 mm (0.2–0.4 in)/yr to as ...
The global average sea level has risen about 250 millimetres (9.8 in) since 1880. [1] Sea surface height change from 1992 to 2019 – NASA. The visualization is based on data collected from the TOPEX/Poseidon, Jason-1, Jason-2, and Jason-3 satellites. Blue regions are where sea level has gone down, and orange/red regions are where sea level has ...
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 ...

Perhaps 30,000 years of volcanic activity form the Deccan Traps in India, or a large meteor impact. 66. Cretaceous–Paleogene boundary and Cretaceous–Paleogene extinction event, extinction of dinosaurs. 55.8.

The wreck is also claimed by U.S.-based salvage company Sea Search Armada -- which insists it found it first more than 40 years ago and has taken Colombia to the UN's Permanent Court of ...
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 ...
