Scientists have used a powerful supercomputer to create a picture of Earth’s distant future, predicting a world where extreme heat, suffocating humidity, and violent volcanic activity could make the planet unlivable. In about 250 million years, the landmasses will merge into a single supercontinent called Pangaea Ultima.
The formation of this supercontinent presents a triple challenge for life: intense heat, high humidity, and increased volcanic activity. Simulations predict temperatures regularly exceeding 40°C (104°F) in the interior, making conditions inhospitable to most mammals, including humans.
Mammals rely on sweating or panting to cool their bodies, but the dense atmosphere in Pangaea Ultima will prevent sweat from evaporating, leading to deadly overheating. The study estimates that around 92% of Earth’s landmass will become uninhabitable for mammals, leaving only narrow coastal strips and polar regions as potential safe zones.
The formation of Pangaea Ultima will also trigger increased volcanic activity, releasing massive amounts of carbon dioxide into the atmosphere and intensifying global warming. A brighter sun is expected to add to the crisis, further destabilizing ecosystems.
While this apocalyptic landscape seems distant, researchers speculate that if humans still exist, survival will require drastic adaptations, such as thicker skin, modified sweat glands, or altered body shapes. Technology might provide faster solutions, like building underground cities to escape the surface heat.
The formation of supercontinents has been linked to mass extinctions in the past, and scientists warn that Earth’s climate is always evolving, with its habitability not guaranteed. This study serves as a stark reminder of the importance of addressing climate change and preserving our planet for future generations.
