Research reveals when the planet could become uninhabitable

One search A recent study led by a team from the University of Bristol, published in the journal Nature Geoscience, presents an alarming outlook for the future of the planet.

According to innovative climate models, Earth could become virtually uninhabitable for most mammals in approximately 250 million years. This brings with it the possibility of a mass extinction comparable to that of the dinosaurs.

Scientists highlight the possibility of a significant intensification of extreme weather conditions when continents merge. This will form a unique supercontinent, resulting in an arid and challenging environment for life.

This new scenario, known as ‘new Pangea‘, would also be associated with a substantial increase in volcanic activity.

By simulating this scenario, it is predicted that high temperatures will worsen as the Sun becomes brighter, releasing more energy and warming the Earth.

The tectonic processes involved in the formation of the supercontinent could also trigger more frequent volcanic eruptions, releasing massive amounts of carbon dioxide into the atmosphere and contributing to global warming.

Most of the new continent would experience minimum temperatures of 40°C, creating even higher daily extremes.

Such an environment would leave the planet largely devoid of food and water resources for mammals, including humans.

The study emphasizes significant implications for the futurehighlighting the importance of not neglecting the current climate crisis, a consequence of greenhouse gas emissions caused by humans.

Although human-induced climate change may generate heat stress and mortality in some regions, the planet is expected to remain habitable until this extreme change in land masses occurs in the distant future.

The researchers highlight the urgent need to achieve carbon neutrality to mitigate the effects of current climate change.

However, they warn that, even if the Earth remains in the ‘habitable zone’ of the solar system 250 million years from now, the formation of a supercontinent with a high presence of carbon dioxide would transform most of the globe into an inhospitable environment for mammals.
