Here we explore the impact of the formation of the next Supercontinent in 250 Myr where the resulting climate will be too hot for almost all mammals to survive leading to extinction

| Abstract | Mammals have dominated Earth for approximately 55?Myr thanks to their adaptations and resilience to warming and cooling during the Cenozoic. All life will eventually perish in a runaway greenhouse once absorbed solar radiation exceeds the emission of thermal radiation in several billions of years. However, conditions rendering the Earth naturally inhospitable to mammals may develop sooner because of long-term processes linked to plate tectonics (short-term perturbations are not considered here). In ~250?Myr, all continents will converge to form Earth?s next supercontinent, Pangea Ultima. A natural consequence of the creation and decay of Pangea Ultima will be extremes in pCO2 due to changes in volcanic rifting and outgassing. Here we show that increased pCO2, solar energy (F?; approximately +2.5%?W?m?2 greater than today) and continentality (larger range in temperatures away from the ocean) lead to increasing warming hostile to mammalian life. We assess their impact on mammalian physiological limits (dry bulb, wet bulb and Humidex heat stress indicators) as well as a planetary habitability index. Given mammals? continued survival, predicted background pCO2 levels of 410?816?ppm combined with increased F? will probably lead to a climate tipping point and their mass extinction. The results also highlight how global landmass configuration, pCO2 and F? play a critical role in planetary habitability |
