This Conclusion brings together the results of the preceding analyses in an account of the limited legal significance of geographical change for maritime jurisdiction. It considers some final instances of State practice that may appear to support the ambulatory thesis. It is demonstrated that while the relevant practice is not unlawful, it does not show that maritime limits must be adjusted in response to geographical change under international law. More broadly, geographical change, including climate-related change, does not threaten the ‘legal order of the seas and oceans’ in the manner that some recent commentary on the implications of climate change for maritime jurisdiction suggests. The existing law does not provide for ambulatory maritime limits or condition continuing entitlement to maritime space on geographical circumstances remaining unchanged. States wishing to retain established entitlement to maritime space and unilaterally established maritime limits in the event of coastal change are permitted to so, unless they no longer possess territorial sovereignty over coastal land (which also depends on whether they intend to give it up). International boundaries, including maritime boundaries, may be fixed or ambulatory, but unless there is clear evidence that an ambulatory boundary was intended, there will be a presumption that established boundaries will not shift with subsequent changes to either the coast or territorial sea baselines. The law was not developed in ignorance of the changeability of coastal geography but makes use of geography in ways that do not leave sovereignty, sovereign rights, or legal limits and boundaries vulnerable to the vicissitudes of nature. The role of geography in the law of the sea contributes to rather than undermines the stability of a spatial and functional division of State rights in the sea. In this regard, it is not necessary to amend the existing law in response to the impacts of climate-related change on the oceans and coasts; instead, it is important to better understand it.
