Supercomputer Simulation Predicts the Future of Humanity in a Changing Climate

Free Subscribtion

Climate change has been a pressing concern in recent years, with scientists warning about its potential impact on the planet and its inhabitants. Now, a groundbreaking study utilizing supercomputer climate models has provided insight into the future of humanity in a changing climate. The study predicts that extreme global warming could eventually lead to the extinction of humans and all mammals. In this article, we will explore the findings of this research and delve into the potential consequences of a warming planet.

The First-ever Supercomputer Simulation

The study conducted by researchers at the University of Bristol used supercomputer climate models to simulate future conditions of the Earth. These models took into account various factors such as the Earth’s climate, tectonic plates, ocean chemistry, and biology. The simulations revealed a “very bleak distant future” for humanity, painting a picture of an uninhabitable planet.

The Formation of a New Supercontinent

According to the study, the Earth’s continents would merge to form a new supercontinent called Pangea Ultima. This merging of continents would create a triple threat for the planet. Firstly, it would lead to the continentality effect, which would result in increased heat for much of the planet. Secondly, the sun would become brighter, emitting more energy and further warming the Earth. Lastly, volcanic eruptions caused by tectonic movements would release significant amounts of carbon dioxide into the atmosphere, exacerbating global warming.

A Hostile Environment Devoid of Life

The consequences of these changes would be dire. The newly-formed supercontinent would be extremely hot, dry, and hostile for mammals, including humans. Widespread temperatures of 40 to 50 degrees Celsius (104 to 122 degrees Fahrenheit), coupled with high humidity, would make survival impossible for most species. Humans and other mammals would struggle to dissipate heat through sweat, leading to their ultimate demise.

Limited Habitability of the Supercontinent

The study estimates that only 8% to 16% of the land on the projected supercontinent would be habitable for mammals. This drastic reduction in habitable land would pose significant challenges for the survival and adaptation of species. The remaining habitable areas would likely be subjected to frequent volcanic eruptions and intense sunlight, further limiting their suitability for life.

Urgency to Address the Climate Crisis

While the study predicts these dire conditions to occur in approximately 250 million years, it serves as a stark reminder of the urgent need to address the current climate crisis. The researchers emphasize that the ongoing climate crisis is a result of human-induced greenhouse gas emissions. Extreme heat events, which are already detrimental to human health, highlight the immediate need for global efforts to achieve net-zero emissions.

Implications for the Future

The findings of this study raise important questions about the long-term survival of humanity. With the potential extinction of humans and all mammals in the distant future, it becomes crucial to explore alternative avenues for survival. The study suggests that humans should consider exploring other planets or finding ways to adapt to extreme environments to ensure our long-term survival.

Lessons from Past Mass Extinctions

Throughout Earth’s history, there have been several mass extinction events that have wiped out a significant percentage of species. The most recent mass extinction event occurred 66 million years ago and led to the extinction of the dinosaurs. These past events serve as a reminder of the fragility of life and the need to protect our planet’s ecosystems.

The Importance of Reducing Carbon Footprint

To prevent the dire predictions of the study from becoming a reality, it is crucial for individuals, communities, and governments to take action to reduce their carbon footprint. This includes transitioning to renewable energy sources, implementing sustainable practices, and promoting conservation efforts. By collectively working towards reducing greenhouse gas emissions, we can mitigate the impacts of climate change and create a more sustainable future.


The first-ever supercomputer simulation on the future of humanity in a changing climate provides a sobering glimpse into a potential future. Extreme global warming could ultimately lead to the extinction of humans and all mammals, creating a hostile and uninhabitable planet. The study serves as a call to action, highlighting the urgent need to address the current climate crisis and reduce greenhouse gas emissions. By taking proactive measures to protect our planet, we can strive for a more sustainable and habitable future for generations to come.

Additional Information: It is essential to note that the predictions made in this study are based on current climate models and assumptions. The future is inherently uncertain, and it is important to continue monitoring and researching climate change to refine our understanding and inform future actions.
