Continental Drift and Geography
- Shifting Landmasses: Plate tectonics will continue to move continents across the globe. The Atlantic Ocean will begin to shrink as the Americas drift closer toward Africa and Eurasia.
- Early Supercontinent Formation: The planet will be in the intermediate stages of assembling a new supercontinent (often called Pangaea Proxima or Pangaea Ultima), altering major ocean currents and regional climates.
- Eroded Ranges: Current mountain ranges will have undergone heavy erosion, while new mountain belts will form where tectonic plates collide.
Biosphere and Life
- Ecosystem Turnover: Most modern species and genera will be long extinct, replaced by new evolutionary lineages and specialized biomes adapted to the shifted geography and climate.
- Thriving Plant and Animal Life: Complex multicellular life, plants, and animals will still flourish, as the severe solar-driven greenhouse crises that eventually boil the oceans are still hundreds of millions of years away (occurring roughly 1 billion years in the future).
