TL;DR
- NASA models indicate Earth has an estimated timeline for the end of complex life, over 1 billion years away.
- The primary cause is the Sun's natural evolution, becoming hotter and increasing global temperatures.
- Increased evaporation leads to a stronger greenhouse effect, destabilizing conditions for life.
- Oxygen loss is predicted to precede significant water loss, making the atmosphere uninhabitable for complex life.
- This long-term process is distinct from and unrelated to current human-caused climate change.
