A recent supercomputer simulation from researchers at the University of Bristol suggests that humanity’s extinction could be inevitable due to long-term climate shifts and tectonic activity. The simulation shows Earth evolving into a new supercontinent, “Pangea Ultima,” in around 250 million years, where intense heat, compounded by volcanic activity and increased solar radiation, would render most of the planet uninhabitable. Dr. Alexander Farnsworth, part of the study, explained that temperatures would reach 40-50 degrees Celsius (104-122 degrees Fahrenheit) globally, with extreme humidity making survival impossible for mammals, including humans.
With just 8-16% of land remaining viable for life under these extreme conditions, humans would struggle to adapt, leading to an inevitable extinction scenario. Although this scenario lies far in the future, co-author Dr. Eunice Lo emphasized that current climate concerns should not be ignored. Today’s climate crisis, caused by greenhouse gas emissions, already affects human health, highlighting the urgent need for net-zero emissions to curb further damage.
Despite this grim forecast, the researchers hope it will encourage action against present-day climate challenges.
