The growing scientific and policy focus on tipping points in the Earth system reflects their potential for profound physical and socio-economic consequences. If crossed, tipping points could trigger abrupt changes that are effectively irreversible on human timescales. Continued Global Warming is predicted to drive major changes across the North Atlantic, pushing key components of the climate system towards potential critical thresholds and abrupt reorganisation. Yet, the nonlinear nature of these systems means that future change is difficult to observe, model, predict, and govern. Early Warning Systems (EWS) have emerged as a potential method of translating our understanding of abrupt changes in the climate and their impacts into useful and actionable information for relevant stakeholders and decision makers.
Important questions remain around how best to inform and govern the response to North Atlantic tipping and what information can be robustly provided considering deep uncertainty.

To address these challenges, this session aims to bring together interdisciplinary perspectives to inform the co-design of EWS that can support tipping point governance. We welcome contributions from observations, modelling, impact studies, and governance. We have particular interest in modern approaches able to inform governance and response, including under deep uncertainty. Our primary focus is on North Atlantic tipping elements, including the Atlantic Meridional Overturning Circulation, Subpolar Gyre and Greenland Ice Sheet. Studies of other tipping elements and their interactions are also welcome. This session builds on themes being explored by the UK Advanced Research and Invention Agency (ARIA) Forecasting Tipping Points programme.
