Contemporary globalization has fostered human development but growing interconnectivity between societies has increased systemic risks (Goldin & Mariathasan, 2014;Goldin & Vogel, 2010). Systemic risks are risks associated with large-scale failures or changes of a system (Helbing, 2013). Disruptions originating in one country can quickly spread beyond national borders and affect large parts of the human population. Addressing such threats is considered a global public good, i.e., goods with benefits that extend to all countries (Kaul et al., 1999). In the study of risks with large-scale impacts, research has often focused on wars, natural disasters, and existential risks (Ord, 2020). However, crises affecting human societies are also related to economic and social issues, or the cooccurrence of social and ecological phenomena (Folke et al., 2021). In the early 21st century, the world has experienced several systemic events with global repercussions, including jihadist terrorism and the war on terror (2001), the global financial and economic crisis ( 2008), the COVID-19 pandemic (2020), and the current broader impact of the Russian aggression against Ukraine on energy, food, and security (2022).These events have provided an empirical basis to study systemic crises. This article aims at providing a broader understanding of the nature, causes, mechanisms, and impact of global systemic crises and their implications for global policymaking and governance. Such understanding is essential for the provision of global public goods to prevent, react to, and recover from shocks. The article
