Climate change has been considered a critical challenge that transcends traditional notions of security, demanding a shift in perspective toward environmental sustainability. Historically, security has been viewed as an inviolable boundary, shaped significantly by the aftermath of World War II, when the international community prioritized peace, territorial integrity, and political independence. However, humanity now faces unprecedented threats that cannot be addressed through rigid or outdated definitions of security. Climate change impacts the entire planet, affecting both living and non-living organisms, and has arisen primarily from anthropogenic activities over the past two centuries. Consequently, solutions must originate from within human societies, emphasizing sustainability alongside action. Despite extensive discourse, meaningful progress remains limited. This paper, drawing on scientific data about climate change’s far-reaching consequences, aims to highlight that climate change, despite theoretical and practical challenges, has the potential to supplant traditional State-centered security as the Grundnorm of international law, serving as the critical threshold that demands a comprehensive reform and reimagining of the international legal framework. It concludes that climate change’s new normativity represents opportunities to reform law and order to ensure life and sustainability.
