he Last Glacial Period (LGP), also known colloquially as the last ice age or simply ice age, occurred from the end of the Eemian to the end of the Younger Dryas, encompassing the period c. 115,000 – c. 11,700 years ago. The LGP is part of a larger sequence of glacial and interglacial periods known as the Quaternary glaciation which started around 2,588,000 years ago and is ongoing. The definition of the Quaternary as beginning 2.58 million years ago (Mya) is based on the formation of the Arctic ice cap. The Antarctic ice sheet began to form earlier, at about 34 Mya, in the mid-Cenozoic (Eocene

My broad conclusion is that an advanced global seafaring civilization existed during the Ice Age, that it mapped the earth as it looked then with stunning accuracy, and that it had solved the problem of longitude, which our own civilization failed to do until the invention of Harrison's marine chronometer in the late eighteenth century. As masters of celestial navigation, as explorers, as geographers, and as cartographers, therefore, this lost civilization of 12,800 years ago was not outstripped

There is indeed compelling evidence of a series of massive glacial surges at the end of the last Ice Age. These correlate with meltwater pulses and peaks of sea-level rise, recorded, for example, in 'drowned' reefs of Acropora palmata from the Caribbean-Atlantic region near the island of Barbados. Acropora is an efficient tracker of rising sea-level because it is a light-loving coral that dies at depths greater than about 10 meters. The Barbados reefs were drowned three times at the end of the l
