The high seas are a critical biodiversity reservoir and carbon sink. Unfortunately, the oceans, generally, and the high seas, in particular, do not feature prominently in international climate mitigation or climate adaptation efforts. There are, however, signals that ocean conservation is poised to occupy a more significant role in international climate law and policy going forward. This paper argues that improved conservation and sustainable use of high-seas living marine resources are essential developments at the convergence of climate action and ocean governance that should manifest, at least in part, as climate-informed high-seas marine protected areas.
