New research: The next supercontinent could destroy humanity

The new research shows that the formation of a new supercontinent could "wipe out" humans and all other mammals (if they exist at all) from Earth in 250 million years, writes CNN.

Namely, scientists from the University of Bristol in Great Britain, using sophisticated climate models, predicted that climate extremes will intensify significantly after the merging of the continents in the supercontinent "Pangea Ultima".

They found that it would be extremely hot, dry and uninhabitable for humans and other mammals, which have not evolved to withstand such high temperatures. To calculate carbon dioxide levels, experts simulated trends in temperature, wind, rain and moisture for the supercontinent and used models of tectonic plate movement.

They also found that with the formation of the supercontinent, more frequent volcanic eruptions, release of carbon dioxide into the atmosphere and warming of the planet will be caused, and the Sun will become stronger, that is, it will emit more energy and further heat the Earth.

"Widespread temperatures of 40 to 50 degrees Celsius and even greater daily extremes, accompanied by high levels of humidity, could ultimately seal our fate." Humans and many other species will no longer be able to live on Earth," says climatologist Alexander Farnsworth from the University of Bristol.

Because of the high temperatures, there would be a shortage of food and water for mammals, and only between 8 and 16 percent of the supercontinent's land area would be habitable. Scientists have also looked at our current climate change problem.

"Although we predict that our planet could be uninhabitable in as little as 250 million years, we are already experiencing extreme heat that is harmful to human health. That's why it's important to get to zero emissions as soon as possible," said climatologist Eunice Law of the University of Bristol.

Scientists have warned for decades that warming must remain below 1,5 degrees Celsius compared to pre-industrial levels to avoid catastrophic changes that would transform life as we know it.

The last mass extinction occurred about 66 million years ago, when an asteroid hit Earth and killed the dinosaurs and most life on the planet.
