Oceans may disappear: humanity faces a new era of global extinction

One day, Earth will once again become a giant supercontinent, and it is unknown whether humanity will be able to survive such changes. The new supercontinent could cause severe cold, intense heat, and even mass extinctions.

This is stated in the Indian Defence Review article.

The ancient supercontinent Pangaea once united all the continents. It began to break apart 200 million years ago. As a result of this split, we know the modern world as it is.

However, scientists warn that the tectonic forces that split Pangaea could change direction.

A 2018 study published in Geological Magazine outlines several major scenarios for how Earth’s next supercontinent might form. And each scenario involves the oceans, whether they expand or shrink.

Scenario One: Neopangea

If the Atlantic Ocean continues to expand and the Pacific Ocean gradually shrinks, the Americas will move away from Europe and Africa, and eventually collide with Antarctica. Then all these landmasses will connect with Europe, Asia, and Africa. Australia will join Asia.

Scenario Two: Pangaea Proxima

In this scenario, the Atlantic and Indian oceans would continue to grow, but over time new subduction zones would appear, pulling the continents back together again. This could result in a ring-shaped supercontinent with a small ocean in the center.

Scenario Three: Aurika

There is a hypothesis that the Pacific and Atlantic oceans will eventually disappear completely. If the Indian Ocean continues to expand, all the continents could be connected along the equator. Such a supercontinent is called Auric.

In this case, the climate could become warmer by about three degrees. The planet would be hotter and possibly drier. Long coastlines, sandy beaches, coral reefs and strong ocean currents would appear.

Scenario Four: Amasya

This model predicts that the Atlantic and Pacific oceans will remain, while the Arctic Ocean will disappear. Almost all continents will then move closer to the North Pole.

Under such conditions, the climate could become dramatically colder. Due to changes in ocean currents, heat would no longer flow normally from the equator to the poles. The poles could become completely covered in ice, and the cold would become even more intense due to the reflection of sunlight by the ice sheets.

What does this threaten?

In any case, the changes will be global. Species will begin to compete with each other for territories and resources. This could cause mass extinctions.

If it gets too cold, most terrestrial species could disappear. If it gets too hot, ecosystems will also be at risk.
