The World Before and After the Sea Rise

Gösta Lindwall and Mikael Kindborg, April 21, 2020

12,800 years ago, the sea level rapidly rose 400 feet (140 m). This was an incredibly dramatic event that changed the Earth itself, and left its mark on the continents and on all life on Earth.

The animals of the spectacular megafauna became extinct, including mammuts, mastodons, giant beavers, large saber-toothed cats, big "terror birds" (giant flightless birds), and giant condors with a wingspan of 16 feet (5 m).

At the time around 13,000 years ago, at the end of the Pleistocene, large areas of the Northern hemisphere were covered with massive ice sheets. According to the "Younger Dryas Impact Hypothesis", the sea rise was the result of a cosmic impact event, which caused the ice to rapidly melt.

Areas affected by the sea level rise were radically transformed. The map of the sea level rise can help to understand the dramatic change that took place.

This map is centered on Borneo, in Maritime Southeast Asia. The land that was above sea 13,000 years ago is green, today's landmass is grey, and today's sea level is blue.

As we can see on the map, before the sea rise there was a big landmass in place of the many islands in the Pacific. It was connected to mainland Asia, forming a very large continent. Australia was also significantly larger, entirely encompassing New Guinea.

What were the consequences of this event? Very dramatic for sure.

Many species became extinct. Humans living in the coastal areas probably died in large numbers, and their land "sunk" into the rising sea. Remaining wildlife and human settlements were isolated as the land was split by the sea.

Before the sea rise, land based animals and humans could travel across the vast continents on foot. After the event, that was no longer possible.

Graham Hancock and others hypothesize that an advanced civilization existed at this time, and that it was destroyed by the cataclysm. This civilization is believed to have spread across the world, having ocean going ships capable of sailing the seas.

Such a civilization must have had cities next to the coast lines, with harbours for ships. These cities were covered with 400 feet of water. This is where we should look today for the remains of an ancient civilization. The coastlines of the green areas of the map are hotspots in the search for the ancient civilization assumed to have existed 13,000 years ago.
