Scientists calculate the date of human extinction, by which time the globe faces extreme high temperatures and high humidity

Researchers say that in 250 million years, all continents on Earth will move together to form a supercontinent called “Pangea Ultima”.

The earth’s land will form a doughnut shape with an inland sea in the middle, which is all that remains of the once Atlantic, while the surrounding Pacific will occupy most of the Earth’s surface.

Scientists are certain that regardless of the exact arrangement, the continents on Earth will slowly merge, forming a large, hot, and dry chunk essentially unsuitable for human habitation.

The tectonic processes will connect all continents, leading to more frequent volcanic eruptions, thus releasing a large amount of carbon dioxide into the atmosphere and further warming the Earth.

Dr. Farnsworth says the emerging supercontinent will effectively cause a triple whammy, including continental effect, hotter sun, and more carbon dioxide in the atmosphere, increasing heat in most areas of Earth. Most regions will have harsh environments, with no food and water for mammals. Temperatures will generally range between 40 to 50°C, with extreme temperatures even higher daily, along with high humidity, ultimately deciding our fate.

Scientists utilized computer climate models to simulate the temperature, wind, rain, and humidity trends on the “supercontinent”.

To estimate future carbon dioxide levels, the research team used models of tectonic plate motion and ocean chemistry to draw up a diagram of carbon dioxide inputs and outputs.

Researchers emphasized that they did not consider carbon dioxide emissions from burning fossil fuels, which is often regarded as the major cause of current climate change.
