Extreme international warming will doubtless wipe all mammals - together with people - off the face of the Earth in 250 million years, based on a brand new scientific research.
Temperatures may spiral to 70C (158F) and rework the planet right into a "hostile environment devoid of food and water", the analysis warns.
The planet would warmth as much as such an extent that many mammals could be unable to outlive - and the Earth's continents would merge to kind one sizzling, dry, uninhabitable supercontinent.
The apocalyptic projections are from the first-ever supercomputer climate fashions.
They counsel the solar would turn out to be brighter, with tectonic actions unleashing large quantities of carbon dioxide (CO2) into the air via volcanic eruptions.
The Earth would turn out to be so sizzling that solely 8% to 16% of the projected supercontinent could be liveable.
Mammals, together with people, are higher tailored to dwelling within the chilly, and are much less in a position to take care of extreme warmth.
'Humans would expire'
The research's lead writer, Dr Alexander Farnsworth of the University of Bristol, stated: "The newly emerged supercontinent would successfully create a triple whammy, comprising the continentality impact, hotter solar and extra CO2 within the environment, of accelerating warmth for a lot of the planet.
"The result is a mostly hostile environment devoid of food and water sources for mammals.
"Widespread temperatures of between 40C to 50C, and even higher every day extremes, compounded by excessive ranges of humidity would in the end seal our destiny.
"Humans - along with many other species - would expire due to their inability to shed this heat through sweat, cooling their bodies."
The authors of the analysis consider CO2 ranges may rise from round 400 components per million (ppm) immediately to greater than 600 ppm by the point of the formation of the supercontinent - named Pangea Ultima.
This assumes, nonetheless, that people cease burning fossil fuels - "otherwise we will see those numbers much, much sooner", warned Professor Benjamin Mills, who calculated the longer term CO2 projections for the research.

'It is essential to succeed in web zero'
The analysis, by a world group of scientists, has been revealed within the journal, Nature Geoscience.
Co-author Dr Eunice Lo, of the University of Bristol, stated: "It is vitally vital to not lose sight of our present climate crisis, which is a results of human emissions of greenhouse gases.
"While we're predicting an uninhabitable planet in 250 million years, immediately we're already experiencing excessive warmth that's detrimental to human well being.
"This is why it's essential to succeed in net zero emissions as quickly as doable."

'Distant future seems very bleak'
The analysis group simulated temperature, wind, rain and humidity traits for Pangea Ultima and used fashions of tectonic plate motion, ocean chemistry and biology to estimate future CO2 ranges.
Dr Farnsworth added: "The outlook in the distant future appears very bleak.
"Carbon dioxide ranges could possibly be double present ranges.
"With the sun also anticipated to emit about 2.5% more radiation and the supercontinent being located primarily in the hot, humid tropics, much of the planet could be facing temperatures of between 40C to 70C.
"This work additionally highlights {that a} world inside the so-called liveable zone of a photo voltaic system will not be probably the most hospitable for people relying on whether or not the continents are dispersed, as we have now immediately, or in a single massive supercontinent."
