Jakarta, CNN Indonesia —
A Education predicting when humans will become extinct due to changes in continental structure that trigger heat that has never occurred on Earth climate change.
Research published in journals Nature Geoscience and led by experts from the University of Bristol, England, it predicts that the next mass extinction on Earth after the destruction of the dinosaurs will occur in at least 250 million years.
Researchers using this first supercomputer climate modeling show how climate extremes will increase dramatically as the world’s continents eventually merge to form one hot, dry and largely uninhabitable super-continent.

These findings project how these high temperatures will continue to increase, as the Sun becomes brighter, emitting more energy and warming the Earth.
The tectonic processes that occurred in the Earth’s crust and resulted in the formation of supercontinents would also lead to more frequent volcanic eruptions resulting in the release of large amounts of carbon dioxide into the atmosphere.
This will result in further warming of the planet, as quoted from the official page University of Bristol.
Lead author Alexander Farnsworth, Senior Research Associate at the University of Bristol, said the emerging supercontinent would effectively create a triple whammy.
It consists of continental effects, a hotter Sun, and more CO2 in the atmosphere.
“The result is a largely hostile environment, without food and water sources for mammals,” he said.
“Temperature rises of between 40 and 50 degrees Celsius, and even more extreme daily temperatures, compounded by high humidity levels will ultimately seal our fate,” he said.
Human adaptation
Mammals, including humans, have survived throughout history thanks to their ability to adapt to extreme weather. Among other things, through adaptations such as fur and hibernation in cold weather, as well as hibernation in warm weather for short periods.
Although mammals have evolved to lower their cold tolerance limits, their upper temperature tolerance has generally remained constant.
This supercontinent phenomenon also makes long-term exposure to excessive heat more difficult to overcome and climate simulations will ultimately prove to be unviable for humans.
“Humans, and many other species, would die due to their inability to lose heat through sweat, thereby cooling their bodies,” Farnsworth said.
Researchers say that climate change which is currently occurring due to human activities still leaves a gap for this planet to remain habitable.
However, when the supercontinent formed, studies showed that only about 8 to 16 percent of the land was inhabitable by mammals.
Farnsworth, visiting Professor at the Tibetan Plateau Earth System, Environment and Resources (TPESER), said the prospects for the future when the supercontinent forms are very bleak.
“Carbon dioxide levels could be twice the current level. With the Sun which is also estimated to emit about 2.5 percent more radiation and the supercontinent is mostly located in hot and humid tropical areas,” he said.
“Most of the planet will face temperatures between 40 and 70 degrees C,” Farnsworth continued.
