That Chili border with Australia or that the same happens between Colombia Y Japan It is possible according to an investigation of the John Curtin University of Australiawhere a technological model was taken with artificial intelligence to predict the movement of the Land in the future.
This estimate is made taking into account several factors such as climate change and the strength of the tectonic plates that are under the oceans that have decayed over time.
“During the last two billion years, the continents of the Land they have collided to form a supercontinent every 600 million years, known as the supercontinent cycle. This means that the current continents will come together again in a couple of hundred million years,” explained Dr. Chuan Huangof the Curtin Earth Dynamics Research Group and the School of Earth and Planetary Sciences.
When and how could the continents be joined?
This estimate was made with a supercomputer in which the movements were simulated and it was found that America is the one that could move until it collides with Asiabecause the Pacific Ocean it will close.
Also, Australia would have a lot of movement in this whole panorama because it would first collide with Asia and then it would be the connection with the American continent, to form amasiaas they named the supercontinent.
“By simulating how Earth’s tectonic plates are expected to evolve, Land Using a supercomputer, we were able to show that in less than 300 million years the Pacific Ocean is likely to close, allowing Amasia to form, debunking some previous scientific theories.” Huang.
So this situation would happen within 200 million years, since the Pacific Ocean is the oldest of which there are records on Earth and began to shrink since the time of the dinosaurs, so it is currently decreasing in size “about few centimeters per year and it is expected that its current dimension of about 10 thousand kilometers will take between two and three hundred million years to close, “says the University that did the research.
The effects of a supercontinent
Although the estimated time that the union of the two continents could take is very long, experts say that this would be a great blow to the planet’s ecosystem and environment.
“Earth as we know it will be drastically different when Amasia forms. Sea levels are expected to be lower, and the vast interior of the supercontinent will be very arid with high daily temperature ranges.” Zheng Xiang Li, co-author of the research and professor in the Curtin School of Earth and Planetary Sciences.
In addition, he added that “the Earth is made up of seven continents with very different ecosystems and human cultures, so it would be fascinating to think what the world will look like in 200 to 300 million years.”
Cities that can be submerged under water
Climate change advances year after year while we know the different consequences it leaves —and what we leave behind— along the way. As if it were a never-ending story, the levels of damage revealed by different scientific studies are getting bigger and more complex. In this case, a recent research work by the Nanyang Technological Universityin Singapore, relieved the 48 largest coastal cities in the world – which concentrate 20% of the world’s population – and found alarming results. According to these experts, at least seven of these locations sink exponentially more than the sea level.
tianjinin China; hochiminhin Vietnam; Chittagongin Bangladesh; Ahmedabad, in India; Jakartain Indonesia, and Yangonin Myanmar, “experience a remarkable sinking with a speed greater than 20 millimeters (mm) per year”, indicates the report. While Rio de Janeiroin Brazil, still does not reach that figure, but they warned that by 2030 about 2 kilometers of the city could be under water if precautionary measures are not taken.
In addition to the aforementioned localities that aroused his concern, there are another 37 that, although they do not have a close risk, were left under observation for future studies. One of them is Buenos Aires, which in the period studied sank a little less than 1 mm. The scientists’ measurements of nayang recorded the height of the coast and the sea levels between 2014 and 2020.
