A groundbreaking study has revealed that Earth could face a mass extinction event in about 250 million years, wiping out all mammal life — even if fossil fuel emissions were halted today.
Researchers from the University of Bristol employed advanced computer simulations to forecast that extreme temperatures between 40 and 70 degrees Celsius would make survival extremely difficult for most lifeforms.
As reported by DailyMail UK, carbon dioxide concentrations are expected to double, making it impossible for species, including humans, to effectively cool their bodies through sweating.
The research, led by Dr. Alexander Farnsworth from the University of Bristol, paints a dire future where much of the planet would become inhospitable to life.
“While we are predicting an uninhabitable planet in 250 million years, today we are already experiencing extreme heat that is detrimental to human health. This is why it is crucial to reach net-zero emissions as soon as possible.”
In an interview with Legit.ng, Abraham Isaac, a Lagos-based medical doctor, highlighted the gradual but serious impact of climate change on health today:
“The effect of high temperature and generally climate change put a strain on the healthcare system. At the moment, workers in some industries are also exposed to some peculiar health hazard which may exacerbate in the future. In the future, water may be so scarce in Nigeria as we are already seeing in Niger-Delta and it could lead to water-borne diseases.”
Scientists also forecast that all continents would eventually converge to form a single supercontinent known as Pangea Ultima — a massive, doughnut-shaped landmass surrounding an inland sea.
This dramatic shift would likely trigger intense volcanic activity, releasing large volumes of carbon dioxide into the atmosphere and causing global temperatures to surge even further.
Alongside tectonic forces, the natural brightening of the sun over time would significantly contribute to Earth’s warming, creating an environment too hostile for mammals to survive.
Estimates from the University of Bristol suggest that by then, only about 8 to 16 percent of the Earth’s surface would remain habitable, making survival an immense challenge.

Throughout history, scientists and thinkers have made various predictions about the possible end of humanity. In 2002, scientists from the Oxford University proposed a 1 in 5 chance that human extinction could occur within the next 100 years due to emerging technologies or natural disasters. Similarly, Stephen Hawking warned that human life could become unsustainable on Earth within 1,000 years unless we find a new planet to inhabit. More recently, climate scientists have warned that without significant action on global warming, catastrophic events could drastically impact humanity as early as the next few centuries.
