The first reason for a far more recent Ice Age than is popularly assumed and dated 10-15.000 yrs. BP or even longer by academia — even assuming multiple Ice Ages like the younger (12.000) & older (14.000) “Dryas”– is to correctly understand when that global ice melt and subsequent flooding of many islands and coastlines all over the world, actually took place.
Ever since underwater archaeology became popular and of age, we can pretty much exactly pinpoint the great Melt Era, by simply dating the very sunken ruins by their culture, style, and by their pottery, pillars, & artifacts found there underwater.
And what was actually found underwater is in no way 10-20.000 years old, for the very simple reason that the discovered ruins are all Bronze Age! They have similar Bronze Age megalithic, polygonic type of walls and pillars from before 1500 BC. as the ruins found above water have, on land! This indicates that the Ice Age happened very recently, before 1500 BC, because then the sea level rose by 125 M. (300 ft) flooding coast-lands all over the globe. The melt also coincided with the subsequent true Climate Change which caused the 1200 BC Bronze Age Collapse! – So mystifying to mainstream academia because their preferred paradigm handicaps proper analysis, as we explain below.
Example 1: Sunken Anapa City Ruins
Look at the submerged walls, pavements, and ruins below the Black Sea off the coast of Anapa City and Sochi, flooded by Ice Age melting. They are typical megalithic polygonic style ruins, as are found on land all over the world, that date from ± 2400 -1500 BC!
This constitutes true Ice Age dating, by far more accurate criteria based on interpretation of cultural and architectural styles, than the popular biased interpretations based on dark and bright slices in Greenland ice cores, which indicate short cold or warm spells rather than entire years!
