The climatic future of our planet arouses many questions, notably through a study published in Nature Geoscience. This research projects the formation of a supercontinent, Ultima Pangeumin around 250 million years. The resulting extreme climate change could make the land largely uninhabitable. With temperatures potentially reaching 70 degrees Celsius, the survival of mammals would be compromised. This perspective highlights the urgency of a collective action to reduce CO2 emissions and avoid such a scenario. What would be the consequences of these changes for humanity and biodiversity?
Researchers mobilized to understand
The study on Pangée Ultima was carried out by an international team of researchers from theUniversity of Bristol andUniversity of Leeds. Funded by the UK Research and Innovation Natural Environment Research Councilthe project used advanced climatic models to predict the future of the earth. Thanks to a fruitful collaboration and the resources of the advanced research center in Bristol, the Dr Alexander Farnsworth and the Dre Eunice Lo led this ambitious project. Their research highlights the importance of reducing CO2 emissions to avoid a catastrophic future. The conclusions drawn underline the need for immediate awareness to meet the climatic challenges.

Simulations and climatic forecasts
The simulations carried out by scientists provide extreme climatic conditions for the future Supercontinent “Pangée Ultima”. The models indicate that the earth could undergo average temperatures of 40 to 70 degrees Celsius. These conditions would be due to an increase in solar brightness and frequent volcanic eruptions. In addition, CO2 levels could exceed 600 ppm, recalling extreme periods of the geological past of the earth. These projections underline the need to reduce our dependence on fossil fuels to avoid such a future. Understanding current climatic mechanisms is crucial to prevent these extreme conditions.

Impact on mammals and humanity
Mammals have shown an adaptability to various climate change during history. However, the projected conditions could exceed their adaptability. According to the Dr Farnsworthonly 8 % to 16 % of the terrestrial surface would remain habitable for mammals. For humanity, the Dre Eunice Lo warns that generalized temperatures between 40 and 50 degrees Celsius could have disastrous effects on human society. These predictions, although distant, strengthen the urgency of taking immediate measures to achieve carbon neutrality. The preservation of our planet and its biodiversity becomes an imperative necessity.

Future research and implications
Although this study projects a distant future, it offers fascinating prospects for research on exoplanets. It demonstrates the influence of the continents on the habitability of a planet. This understanding could transform our approach to astrobiology and help us identify habitable planets beyond our solar system. Above all, this research reminds us that our immediate priority must be the preservation of our own planet. How will these new knowledge be used to guarantee a lasting future and avoid catastrophic scenarios?
While these alarming climatic predictions are emerging, it is crucial to identify the immediate actions to be taken to limit climate change. Each decision made today will have repercussions on the future of our planet. What measures are we ready to adopt collectively to respond to this unprecedented challenge and ensure a viable future for future generations?
