Impending Supercontinent Threatens Mammalian Existence

Scientists predict that in 250 million years, Earth's continents will merge to form a supercontinent called "Pangea Ultima," resulting in inhospitable conditions for most mammals. The formation of this supercontinent will lead to increased volcanic activity and a hotter sun, causing land surface temperatures to exceed 40℃ and transforming much of the continent into a vast, hot desert. The average annual land temperature would increase from the pre-industrial average to approximately 24℃, reducing habitable areas on Earth to just 54%. The projected location of Pangea Ultima at the equator, along with other factors, would contribute to this warming. The increased solar intensity and elevated CO₂ levels would further reduce Earth's habitability, leaving only a quarter of the planet's surface habitable. Mammals' adaptability may not be enough to survive these extreme conditions, as their temperature thresholds are surpassed, making it challenging for them to regulate their body temperature.
