The authors argue that the world’s dependence on networks and critical infrastructure renders it increasingly vulnerable to “cascading disasters” in which “it is common for the secondary effects to be new sources of impact, which may be more devastating than the original trigger.” To help analyze the vulnerability pathways through which disaster cascades propagate, they […]

This article introduces a special issue of the Journal of European Public Policy on Europe’s polycrisis, setting out the mechanisms of its “politics trap” and the strategies that have been utilized to try to deal with its constraints. It argues that “this ‘polycrisis’ is fracturing the European political system across multiple, simultaneous rifts, thereby creating a ‘polycleavage’.”
Melanie Hart, Jordan Link, and Ngor Luong of the Center for American Progress translate and discuss Chinese Central Political and Legal Affairs Commission Secretary-General Chen Yixin’s effort to explain President Xi Jinping’s “ten fundamental insights” on “preventing and resolving major risks”. Yixin considers black swan events and risk interactions, noting that “All categories of risk

Where regime shifts (also known as critical transitions) are generally studied within a single ecosystem, the authors explore cascading regimes shifts across multiple ecosystems. Drawing on the Regime Shifts Database of over thirty well-documented regime shifts, they identify three causal pathways by which a regime shift in one ecosystem relates causally to a regime shift

Susan Cutter traces the etymology of the multiple, overlapping terms used to describe “types of situations where there is a single triggering hazardous event resulting in large-scale impacts to lives and livelihoods, which in turn generate secondary or tertiary ‘events’” (p. 17). She notes that the terms “compounding effects” and “cascading hazards” refer to cases

The paper proposes that reinforcing feedbacks could push the earth system toward a planetary threshold past which lies an irreversible “Hothouse Earth” scenario that catastrophically disrupts ecosystems, societies, and economies. The authors suggest that a deep transformation based on a fundamental reorientation of human values and operating systems is necessary, as well as resilience-building strategies

Seth D. Baum and Anthony M. Barrett argue that there are underappreciated systemic interactions between catastrophic risks. Actions taken to mitigate one catastrophic risk may increase or reduce another catastrophic risk. To address these interactions, leaders must use an “integrated assessment” of the whole collection of global catastrophic risks to ensure efforts to remediate one

Peter Turchin and his colleagues explain their design of a computational method to predict social collapse: multipath forecasting. By incorporating quantitative data (i.e. demography) as well as qualitative data (i.e. cultural value), a system trained on historical data predicts “a history of possible futures, in which the near- and medium-term paths of societies are probabilistically
The authors clarify the systemic risk concept using the Global Financial Crisis as an example. They explain how global systems involve micro and macro-dynamics interacting with each other and their environment, leading to stable periods and multiple possible future scenarios. Some of these scenarios may pose catastrophic risks, so that agents must confront systemic risk.

Global catastrophic biological risks (GCBRs) are hazards caused by biological agents that result in massive disruptions to society. The authors analyze historical GCBRs, such as H1N1 and the Black Death, and their interactions with other complex aspects of society. The rapid depopulation caused by the Black Death, for example, generated “broad, lasting, and complex effects
