## Emergence
**Emerges from:** [parameter](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-parameter.condition), [drift](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-drift.aimless), [wall](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-wall.range-end)

**Through:** time.dimension

**Novel properties:**
- window-of-opportunity.threshold

## Examples
- The Opportunity rover's solar panels lost enough efficiency by 2018 that a dust storm ended its operations permanently. *(engineering)*
- After the 2008 financial crisis, Iceland’s banks exceeded the threshold where domestic depositors could recover full value. *(economics)*
