Evolution of the polycrisis: Anthropocene traps that challenge global sustainability

Using expert solicitation, the authors identify 14 “evolutionary traps” (global, technological, and structural) that risk locking humanity into unfavorable (maladaptive) trajectories that seriously restrict its ability to adapt to the Anthropocene. These traps develop over four phases: initiation, scaling, masking (of harmful interactions), and trapping. The fourth phase involves one of five trapping mechanisms: constraints, […]

Navigating the polycrisis—governing for transformation: The 2024 agenda for the systems community

In this article, the authors argue that the polycrisis is the manifestation of challenges outlined by the earlier scholarship of the “global problematique,” a set of systemically related factors including political, social, and ecological challenges such as pollution, resource depletion, and population growth. The polycrisis is recognized as the outcome of profound governance crises that

The Era of Global Risk: An Introduction to Existential Risk Studies

This edited volume argues that humanity has entered a fundamentally novel era of existential risk. These risks range from global-scale natural disasters (like volcanic super-eruptions) to anthropogenic environmental destabilization (like climate change and loss of biosphere integrity), and from calamities that spread rapidly around our highly networked planet (like viruses and cyber threats) to the

Let’s Avoid ‘Trigger Fixation’

The authors argue that a trigger event can’t start a crisis by itself; some underlying stress or stresses must also be operating. They contend that leaders should pay far more attention to these stresses, because they’re ultimately far more important. The original title of the article was “Let’s Avoid ‘Trigger Fixation.” The Globe and Mail

Response Diversity as a Sustainability Strategy

The authors argue that the most effective way to build general resilience in an increasingly volatile and uncertain world is to foster “response diversity… a system’s variety of responses to disruptions of all kinds.” That entails maintaining a variety of ways to carry out key system process (ideally at different spatial and temporal scales) that

Global Risks Report 2023

This 18th edition of the World Economic Forum’s Global Risks Report is based on a risk perceptions survey of 1200 experts on the likelihood, severity, and interconnections between 37 global risks. It finds that the biggest risk in the next two years is the cost of living crisis, and the biggest risk in the next

Top Risks 2023

Ian Bremmer and Cliff Kupchan present their top ten geopolitical risks for 2023: an increasingly rogue and reckless Russia; an increasingly powerful and unconstrained Xi Jinping; the weaponization of artificial intelligence; shockwaves of global inflation; Iran backed into a corner; higher energy prices; reversals of development; political divisions in the United States; the disruptive digital

Global Catastrophic Risks 2022: A Year of Colliding Consequences

The report provides an overview of several catastrophic risks that are potentially global in scope: weapons of mass destruction, pandemics, artificial intelligence, asteroids, climate change, super-volcanic eruptions, ecological collapse, population growth, and climate tipping points. For each risk, it explores the key factors that affect the risk levels and the extant governance frameworks that address

Dynamics of Tipping Cascades on Complex Networks

This article examines network models to better predict tipping points, defined as “a critical threshold (tipping point) at which a tiny perturbation can qualitatively alter the state or development of the subsystem.” By using moisture measures in the Amazon rainforest as a model system, the authors determine that “clustering and spatial organization increase the vulnerability
