Global Food Insecurity and Famine from Reduced Crop, Marine Fishery and Livestock Production due to Climate Disruption from Nuclear War Soot Injection

The authors examine the global food consequences of nuclear war on food security. Through six scenarios of stratospheric soot injection resulting from nuclear detonations, and using integrated climate, crop, and fishery models, they estimate post-war national food calorie availability after the depletion of stored food. The findings reveal that soot injections exceeding 5 Tg would cause […]

An Embarrassment of Changes: International Relations and the COVID-19 Pandemic

Mathew Davies and Christopher Hobson argue that the COVID-19 pandemic is part of an ongoing polycrisis that requires significant changes to the ways in which the discipline of International Relations understands the world. They propose that “Polycrisis is a way of capturing the tangled mix of challenges and changes [that] closely interact with one another,

Replacing Sustainable Development: Potential Frameworks for International Cooperation in an Era of Increasing Crises and Disasters

Reviewing international cooperation on social and environmental change, and particularly the failure to achieve the Sustainable Development Goals, Jem Bendell argues that the Sustainable Development framework is unable to address the increasing crises and disasters faced by the world today. As an alternative, he proposes an upgraded form of Disaster Risk Management that is detached

Decline and Fall, Growth and Spread, or Resilience? Approaches to Studying How and Why Societies Change

Daniel Hoyer examines qualitative, case study, complex system, and societal dynamics approaches to explain “historical precedents of collapse, growth, and resilience.” He explains drawbacks to each method, and stresses “the importance of developing formal (especially mathematically articulated) mechanistic theory, as only by explicating what we think drives societal outcomes in a structured, formal way can

Global Risks of Infectious Disease Outbreaks and its Relation to Climate

The paper examines whether the aggregated effects of climate change and modes of climate variability affect the propensity for infectious disease outbreaks through an extreme value statistics approach. The analysis reveals that fatalities from outbreaks follow a power-law distribution, indicating that extreme events like the COVID-19 pandemic fall within expected statistical bounds. The authors find

Interacting Tipping Elements Increase Risk of Climate Domino Effects under Global Warming

The authors use Boolean and dynamic network models to investigate how the the interactions of climate tipping elements (Greenland Ice Sheet, West Antarctic Ice Sheet, Atlantic Meridional Overturning Circulation (AMOC), El Niño-Southern Oscillation, and Amazon rainforest) could produce domino effects (or tipping cascades) across other tipping elements. They find that tipping points in the Greenland

Integrating Collapse Theories to Understand Socio-Ecological Systems Resilience

This longitudinal case study applies collapse theory to the Piura Basin of Peru, a region subject to extreme El Niño weather events, that has previously seen societal collapse in the ancient Moche civilization. By examining factors from the Robustness Framework such as centralized governance, system interconnectedness, and central elites, the researchers examined the interactions of

Anatomy and Resilience of the Global Production Ecosystem

The authors argue that the worldwide production and distribution of food, fuel, and fibre has created a “global production ecosystem” subject to immense simplification, intensification, and control by humans attempting to maximize efficiency. The resulting system is homogenous, highly connected, and has weak feedbacks – “features [that] converge to yield high and predictable supplies of
