The reality of climate change and security has become a central theme in contemporary international policy and academic discussions, recognising climate change not just as a serious environmental and economic issue, but also as a significant security threat. This study examines the distinctions between immediate climate-induced emergencies and potential future events, highlighting the need for objective and explicit clarifications to avoid preventive measures that could compromise fundamental rights. It traces the historical gap between concern and action on climate change and investigates the emerging militarisation of responses to climate change, with a focus on lessons learned. By analysing international policies, strategies, and legal regulations, the article underscores the importance of distinguishing between necessary urgent actions and current emergencies, and proposes some solutions based on the precise definition of certain terms.
