‘Supercontinent’ Pangea Ultima could make Earth uninhabitable, study says

Our planet was not always as we know it, with clearly defined continents and oceans that we already identify. Before humans walked, even before dinosaurs appeared, there was one large landmass that scientists have named Pangea.

Pangea was one ‘supercontinent’ That existed 250 million years ago, between the Paleozoic and the beginning of the Mesozoic. This continental mass was surrounded by a single sea, called Panthalassa. In this kind of gigantic desert the first dinosaurs and other animals that are now extinct appeared.

Why is it dangerous that the Earth’s pole has shifted 80 centimeters?

Possibly, Pangea broke up and gave way to the formation of the continents we have today. However, scientists estimate that in another 250 million years the land masses will move again and form a new ‘supercontinent’, which would be named Pangea Ultima.

This will be Pangea Ultima

According to a study carried out by scientists from the University of Bristol, the climatic events such extremes will give way to this merger of continents. By analyzing climate models of the distant future with a supercomputer, they discovered that Pangea Ultima will not be a habitable place.

That is, the mammal and human species that exist in 250 million years will probably also exist They could not survive in this place. The main reason would be excessive heat, which would come not only from the sun, but also from constant volcanic eruptions.

According to Alexander Farnsworththe lead author of the paper published in Nature Geoscience, “the newly emerged supercontinent would create a triple whammy that would include the effect of continentality, a hotter sun and more CO2 in the atmosphere.”

In Pangea Ultima they would feel widespread temperatures between 40 and 50 degrees Celsius and high humidity.

“Humans, like many other species, would die as a result of their inability to eliminate this heat by cooling their bodies through sweat,” Farnsworth explains.

Consequences of climate change

Scientific research emphasizes the importance of climate change in its analysis.

“Although we predict that the planet will be uninhabitable within 250 million years, today we are already experiencing extreme heat that is harmful to human health. “That’s why it’s critical to reach net zero emissions as quickly as possible,” he said. Eunice Locoatura of the study.

Benjamin Mills, professor of Earth System Evolution at the University of Leeds and co-author of the study, explained that the research was done as humans stopped burning fossil fuels in the present. Otherwise, the effects of Pangea Ultima would become noticeable much sooner.

“It is critical not to lose sight of our current climate crisis, which is caused by human emissions of greenhouse gases,” Lo added. (JO)
