Its effects are not only geographical but also directly impact international law. One of the most significant consequences involves State territory and maritime entitlements, as baselines shift due to rising sea levels. This context has sparked debate over whether to adopt fixed or ambulatory models for baselines. However, this debate remains inconclusive, with many questions unresolved and few definitive answers. This article aims to update the current state of this debate and offer a critical perspective on legal fictions that have sometimes benefited powerful States but not others. It examines whether international law continues to uphold principles of equity or remains influenced by major powers, especially considering the doctrines of <em>Empire by Purchase</em> and <em>Lebensraum</em>.</p> José María OLVERA AMADO Copyright (c) 2025 Juris Gentium Law Review 2025-11-11 2025-11-11 11 1 1 23 10.22146/jglr.v11i1.22394
