# State-Dependent Catastrophe **Domain:** Catastrophic Risk / Climate / Resilience / Infrastructure **Doc Type:** Canonical Bridge Concept **Maturity:** Developed **Concept Status:** Corpus term by Bryant McGill; grounded in established compound and cascading-risk analysis ## Definition **State-Dependent Catastrophe** is the principle that the civilizational severity of a hazard depends on the condition of the system it strikes. The physical event may be unchanged while its consequences differ radically because ecological redundancy, food reserves, water security, grid stability, public health, supply chains, institutional trust, or adaptation capacity have already been depleted. An asteroid, drought, heatwave, cyberattack, pandemic, or crop shock therefore cannot be evaluated only by its isolated magnitude. The relevant object is the event acting on a particular receiving state. ## Compound and Cascading Risk The concept connects three layers: 1. **Hazard** — the initiating physical, biological, technological, or political event. 2. **Baseline state** — existing heat, water, food, biodiversity, debt, infrastructure, migration, and governance conditions. 3. **Cascade** — synchronized failures in production, transport, communications, health, legitimacy, and conflict management. The catastrophe often lives in the cascade rather than the initial event. A society with reserve capacity can absorb disruption; a society already near hard limits can convert a regional event into systemic failure. ## Planning Consequence Risk management must preserve slack, diversity, substitutability, verified data, restoration capacity, and multiple operating modes. This links climate adaptation to continuity planning, planetary defense, resilient computation, food and water systems, and [[wiki/Civilizational Payload|civilizational payloads]]. It also explains why [[wiki/Marsification|Marsification]] can increase safety locally while increasing systemic dependence on energy, sensors, software, and maintenance. ## Evidence Boundary Compound and cascading risks are established fields of study. The corpus term names their civilizational junction. It does not establish that any particular catastrophe is imminent, that exercises are predictions, or that one risk programme secretly coordinates all others. ## Sources / Provenance - Defined and applied in [[articles/The Last Migration Will Not Be Human|The Last Migration Will Not Be Human]]. ## See Also [[collections/MARS|MARS]] · [[collections/Climate Justice and Meritocracy|Climate Justice and Meritocracy]] · [[wiki/Biosphere|Biosphere]] · [[wiki/Resilience|Resilience]] · [[wiki/Vulnerability Assessment|Vulnerability Assessment]] · [[articles/Climate Systems as Human Resilience Platforms|Climate Systems as Human Resilience Platforms]]
