## Definition
**Systems where output is not proportional to input**, exhibiting sensitivity to initial conditions, bifurcations, and emergent behavior. Nonlinear systems produce qualitatively different dynamics than linear approximations at large scales.
---
## General Context
Climate systems, ecosystems, and social dynamics are fundamentally nonlinear. Chaos theory, bifurcation analysis, and complexity science provide tools for understanding nonlinear behavior.
---
## Key Insight
Nonlinear systems limit predictability—tiny differences in starting conditions produce large outcome variations (butterfly effect). This creates fundamental forecasting limits distinct from mere information scarcity.
