Scientists predict a new mass extinction that will wipe out humans and all mammals

In the grand tapestry of time, human existence stands as a fragile thread woven into the very fabric of Earth’s history. And now, a harrowing vision of our distant future unfolds, where extinction looms ominously, rivaling the prehistoric fate of the dinosaurs. (earth.com) This revelation emerges from a groundbreaking study, where the forces of nature conspire to create a catastrophic spectacle, taking center stage, approximately 250 million years from today.

In a world of academia, where curiosity sparks innovation, a beacon of revelation shines through. This time, it’s a team of intrepid researchers who utilize the mighty power of supercomputer climate models, painting a stark picture of our potential demise. (earth.com) They unveil a future that seems plucked from the annals of science fiction but is firmly rooted in scientific fact. These computer models, for the first time, simulate a world where Earth’s continents cease their eternal dance of separation and unity, instead merging into a singular, imposing supercontinent. In doing so, they set the stage for an unimaginable shift in our planet’s fate.

The consequences of this climatic theater are nothing short of apocalyptic. An amalgamation of continents would spell disaster on an unparalleled scale. Extremes would become the norm, and Earth would transform into a hostile, unforgiving terrain. Heat would reign supreme, and it’s not just an inconvenience; it’s a death sentence. Mammals, from the mighty to the minuscule, would find themselves ill-equipped to adapt to such searing conditions. Humanity, despite its remarkable achievements, would crumble under the weight of unrelenting heat, becoming but a memory in the annals of Earth’s history. (earth.com) (glonme.com)

But that’s not the entire plot. Our sun, our eternal companion in the cosmic ballet, would also take center stage. As continents collide and fuse, the sun’s brightness would intensify. Its fiery rays would bear down upon Earth with unyielding force, unleashing energy like never before. In a world already stretched to its limits, this increased solar onslaught would compound our predicament, pushing us to the brink.

The story doesn’t end there. The drama unfolds in volcanic eruptions, a relentless barrage of nature’s fury. (nature.com) (earth.com) As the newly formed supercontinent grapples with its birth pangs, volcanoes would burst forth with terrifying regularity. They spew forth not just molten rock but also carbon dioxide, the notorious greenhouse gas. This carbon dioxide, in all its malevolence, would cloak the Earth in a suffocating blanket, leading to the notorious curse of global warming. It’s the recipe for disaster.

In the grand narrative woven by these researchers, it’s a trifecta of doom. (earth.com) (bristol.ac.uk) The rise in carbon dioxide, the relentless blaze of the sun, and the continental chaos give birth to a new reign of terror. The world we once knew, with its diverse climates and temperate zones, would be extinguished. A vast portion of our planet, from pole to equator, would exist as a torrid wasteland, where temperatures rise to an unbearable 40 to 70 degrees Celsius. In this relentless furnace, life as we know it becomes unsustainable.

Mammals, who have triumphed over countless challenges throughout Earth’s history, would meet their match. Evolution has granted us the ability to endure cold, with features like fur and hibernation. Yet, our tolerance for high temperatures has remained relatively stagnant, frozen in time. The very mechanisms that allowed us to thrive in our temperate world would betray us in this scorching crucible. As the sweat upon our brows fails to provide solace and our bodies sizzle in the relentless heat, humanity would find itself at the crossroads of extinction.

It’s a tale that sears the soul, painting a vivid, agonizing picture of humanity’s final moments, brought about by the Earth’s climatic upheaval. (earth.com) Dr. (earth.com) Eunice Lo, a co-author of this chilling narrative, raises a clarion call, an urgent plea. (glonme.com) She emphasizes that the climate crisis we face today, as a result of human-induced global warming and greenhouse gas emissions, must be met with swift and decisive action. (linkedin.com) (earth.com) The extreme heat that looms on the horizon, already a harbinger of human suffering, underscores the unassailable need for a global, collective effort to strive for net-zero emissions.

The researchers stand as modern-day soothsayers, offering us a glimpse into a future that we must not allow to pass. (glonme.com) Through the lens of climate models, they venture into the very heart of our planet’s climatic crucible, projecting temperatures, wind patterns, rainfall, and humidity trends for the supercontinent of the future, known as Pangea Ultima. Their models tell a grim tale, where carbon dioxide levels rise from today’s 400 ppm to over 600 ppm in this new era, should humanity cease its reliance on fossil fuels. If we don’t, this future could arrive far sooner. Professor Benjamin Mills, guiding the calculations for carbon dioxide, paints a picture of despair, where Earth is plagued with double CO2 levels, an onslaught of solar radiation, and a supercontinent that rests in the blistering, humid embrace of the tropics.

But there’s more to this revelation than just a harrowing future for our world. It serves as a stark reminder of the significance of our planet’s tectonic and continental layout. In a moment of (earth.com)
