Once upon a time all continents on the Earth were a single land mass, which was called Pangea. About 200 million years ago, this continent split into parts along tectonic plates. But the scientists believe that it is not forever. In the future, the disintegrated continents may reunite. The employees of the American Geophysical Union believe that if it happens, the Earth's climate will change and the event will affect the habitability and stability of our planet.
A detailed study of that alleged process is important for the search for life on other cosmic worlds. How the new supercontinent will look like and where it will be located is still unknown to science.
But the forecast is that the disintegrated 200 million years ago, with the exception of Antarctica, will unite. It is possible that it will happen around the North Pole, forming a new land area of Amasya. Another version is the continent of Aurica, which forms 250 million years later around the equator. The scientists compiled a computer model that roughly demonstrates how the formation of a new continent will affect the Earth as a whole.
Amasya and Aurika will have very different climate impacts. If tectonic plates converge at the equator, then the planet will become warmer by 3 degrees. In the scenario of Amasya formation, the poles will become colder and during the year they will be covered with ice, which will reflect heat into outer space.
That option will bring the Earth a large amount of snowfall. So the researchers think, in their forecasts - the formation of new ice sheets, which will gradually lower the temperature of the Earth, and, possibly, the waters in the oceans.
It can lead to difficulties in the agro-industrial complex: the number of areas for agricultural work will decrease. Aurica, on the other hand, will bring excess heat to the planet, as a result of which the polar ice caps will disappear.
Such simulations may not be accurate. The researchers say that at least 10 years from now, this issue should be revisited in order to make new forecasts based on current temperatures and climatic conditions.
