Global ocean deoxygenation driven by fossil fuel emissions, overfishing, and inequitable water governance threatens planetary stability

Recent oceanographic models quantify the synergistic effects of warming, stratification, and nutrient loading, projecting a 30% decline in global oceanic oxygen by 2100 under business‑as‑usual emissions. Empirical measurements from autonomous gliders corroborate these trends, providing high‑resolution data for targeted interventions.
Ocean deoxygenation is a systemic symptom of intertwined climate warming, nutrient overload, and extractive fisheries, amplified by governance structures that marginalise Indigenous stewardship and coastal communities.
Historical analogues and cross‑cultural practices reveal that communal, relational management can restore oxygen balance, while scientific modelling shows that only coordinated carbon mitigation and nutrient reduction can avert tipping points. By integrating regenerative land use, equitable carbon pricing, Indigenous co‑management, and transparent monitoring, the global community can transform the current trajectory from irreversible decline to resilient restoration, honoring both ecological integrity and cultural continuity.
