Pangea Ultima: New supercontinent could make 92% of Earth's land uninhabitable for humans. Here's when

Earth's continents may look permanent on a human timescale, but over hundreds of millions of years they are constantly being reshaped by tectonic forces. One possible future map is already being modelled by scientists and it could create a planet dramatically less hospitable to mammals. Around 250 million years from now, Earth's continents are expected to converge into a new supercontinent known as Pangea Ultima. The exact configuration remains uncertain, with several possible supercontinent scenarios proposed, but the climate consequences of a giant, consolidated landmass could be severe.
