Category Archives: Polycrisis

Google AI: A polycrisis is a single situation where multiple, distinct global crises occur simultaneously and interact in ways that amplify each other, making the overall damage significantly worse than the sum of its individual parts. Instead of dealing with isolated, sequential emergencies, a polycrisis features intersecting networks of stress across economic, geopolitical, ecological, and technological systems.
Core Characteristics
Causal Entanglement: A crisis in one system (e.g., a geopolitical conflict) directly triggers or worsens a crisis in another system (e.g., energy prices and global food supply chains).
Feedback Loops: The compounding effects bounce back and forth between systems, creating highly volatile and unpredictable domino effects.
Systemic Overwhelm: Because the crises are deeply linked, they cannot be successfully resolved one at a time, frequently paralyzing traditional governance and risk-management strategies
