Global Polycrisis: The Causal Mechanisms of Crisis Entanglement

The authors translate polycrisis from a loose concept into a research agenda by providing the concept with a substantive definition, highlighting its value-added in comparison to related concepts, and developing a theoretical framework to explain the causal mechanisms currently entangling many of the world’s crises. In this framework, a global crisis arises when one or more fast-moving trigger events combines with slow-moving stresses to push a global system out of its established equilibrium and into a volatile and harmful state of disequilibrium. The paper then identifies three causal pathways—common stresses, domino effects, and inter-systemic feedbacks—that can connect multiple global systems to produce synchronized crises.
