9.8 South America and Antarctica

Certain areas of land that aren’t very far beneath the surface of the water will be shoved upward and incorporate quite a few of what is now known as the Caribbean Islands. He’s not positive about the final shape of this land, but it will be a fair-sized island.
The chain of mountains along the western side of South America will rise somewhat forming a slightly smaller continent with many islands around it; some of them will be of fairly good size. Particularly the jungles of Brazil and the Guianas, and most of the Amazon Basin, will be under water. The southern chain of islands near Tierra del Fuego will raise up and be part of the land. From there new islands will connect with Antarctica.
When the poles start melting because of the Earth shift the South Pole will move upward, possibly into southern South America.
Antarctica will shift north toward the equator and a bit to the east, as will South America. This will move it into a more temperate climate. It won’t break up as quickly as other land masses because much of what holds it together is ice. There will be major cracks in it, and eventually the land will separate because of the ice melting, but that won’t happen for a while. It will be habitable and people will be able to go there. But it won’t be worth living on because the ice will remain for a long time and nothing will grow there.
There will be a chain of islands emerge northward from the Hawaiian Islands. This will be several islands so close together that one could swim from one island to the next. It will form a natural barrier to the ocean currents, so that part of the ocean (the right side) will have its own pattern.

The main areas of new land will be in the southern Pacific and Atlantic in the area of Antarctica. If you’re looking for Atlantis, the only thing that comes close to that is that is the land mass in the Caribbean. There will be no large continents or segments rising for millions of years.
