In 32 million years, Earth’s geography will look subtly altered due to plate tectonics, featuring rearranged coastlines and a modified Mediterranean. While not yet the extreme supercontinent predicted for 250+ million years, this future Earth will likely feature dried-up Great Lakes, reshaped British Isles, and a “smooshed” Italy. 

• Geological Shifts: Continental movement will have caused significant changes to coastal regions. The Mediterranean Sea may be significantly reduced or dried up.
• Topography: Some inland areas, such as the Great Lakes region, could be dry, while others might undergo uplift, changing the map’s recognizable shapes.
• Climate & Environment: Although not as extreme as the future Pangea Ultima (which is predicted for 250 million years from now), the climate will continue its natural, long-term shifts in erosion and aridification.
• Evolutionary Changes: Life on Earth will have evolved significantly, with new species occupying ecological niches in a warmer world where some current continents have merged or shifted. 
• This time frame represents a “medium-term” future where the planet remains recognizable, but continental drift has created a new, distinct map of the world. 

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.
