In 25 million years, Earth’s geography will be recognizable but shifted: Africa will drift north to seal the Mediterranean, Australia will move into Indonesia, and the Atlantic will widen. Mammals may still exist, but the planet will be navigating significant climate shifts, with more volcanic activity and altered coastal regions shaping the future.
- Geological Changes: While not yet a full supercontinent, the continents will be on a path towards merging. The Atlantic Ocean will likely widen, while the Pacific will start to shrink. Significant mountain building will occur, particularly as Africa continues its collision with Europe.
- Climate and Environment: Increased tectonic activity may lead to higher volcanic activity, potentially increasing carbon dioxide levels. This could create a warmer, more humid, greenhouse-like climate, with far fewer, if any, polar glaciers.
- Life and Habitability: The landscape will be undergoing major transformations, which will continue to push evolution in new directions, potentially favoring species adapted to warmer, more extreme conditions.
- A Slowed Evolution: Twenty-five million years is a relatively short time in geological terms, so while the world will look different, it will not be the completely unrecognizable, barren, and nearly uninhabitable supercontinent (Pangaea Proxima) predicted for 250 million years from now.
