Non-technical summary In response to the concerns of a growing number of crises, we trace the temporal trends, distribution and co-occurrences of shocks sudden events with noticeable impacts on 175 countries from 1970 to 2019. Our analysis shows that shocks have not evolved uniformly over time and space: after becoming more co-occurring between 1970 and 2000, they then showed a regionally dependent shift in patterns. Our results highlight that regional differentiation is not incidental but constitutive of polycrisis dynamics, and that any effort to theorize, anticipate, or navigate polycrisis must account for this spatial heterogeneity. Technical summary Polycrisis has emerged as a new property of the Anthropocene. Defined as the convergence of crises across multiple systems, polycrisis calls for a paradigm shift in how crises are perceived and managed. Characterizing polycrisis dynamics is the first step in that direction but is made difficult by the complex and non-linear mechanisms at play. To overcome this challenge, we adopt a social-ecological systems (SES) approach to decompose polycrisis dynamics into two interrelated processes: shocks sudden events with noticeable impacts, and creeping changes slow processes that have a potential significant impact on society or the biosphere. We then develop and analyse a harmonized database capturing the occurrence of six categories of shocks (climatic, geophysical, ecological, economic, technological, and conflict-related) across 175 countries between 1970 and 2019. Our analysis reveals a significant rise in shock co-occurrences until 2000, particularly at the intersection of conflict, climate, and technological disruptions. After 2000, co-occurrence began plateauing or declining in all regions, yet at different levels. Our findings highlight the importance of a regionalized and typologically nuanced approach to understanding polycrisis. Our work also paves the way to an integration of polycrisis theory and multihazard methodologies for developing more effective and anticipatory polycrisis management. Social media summary Dynamics of the polycrisis reveal regional differences, with a possible shift in the interaction of shocks from 2000.
