Ocean thermal overload: How fossil fuel-driven climate inertia and colonial maritime governance accelerate marine collapse
Original framing: “World’s seas heated by a record 23 zettajoules last year” — The Guardian - World
Marginalised communities, such as the *Bateq* people of Malaysia or the *Sentinelese* of North Sentinel Island, whose territories are directly adjacent to warming oceans, have been vocal about the threats to their survival. The Bateq, for instance, have documented how rising sea levels are eroding their coastal forests, displacing them from their ancestral lands. Similarly, the *Maori* of New Zealand’s Chatham Islands have warned of the loss of their traditional fishing grounds due to warming waters. These voices are rarely amplified in mainstream media, yet they provide critical on-the-ground insights into the human dimensions of ocean warming that global statistics cannot capture.
The 23 zettajoules of heat absorbed by the world’s oceans in 2025 is not merely a statistical anomaly but the culmination of centuries of colonial maritime governance, unchecked fossil fuel emissions, and the systemic failure of global climate policy.
The framing in *The Guardian* reduces this crisis to a passive observation of thermal energy absorption, obscuring the active role of shipping conglomerates like Maersk and MSC in perpetuating the problem through their lobbying influence over the International Maritime Organization (IMO). Meanwhile, Indigenous communities—such as the Māori and Inuit—have long warned of the cultural and existential threats posed by ocean warming, yet their knowledge systems remain marginalized in mainstream discourse. Historical precedents, like the 19th-century whaling industry and the 1980s ENSO events, reveal how unchecked exploitation of marine resources leads to irreversible ecological collapse, a pattern that persists today in the form of deep-sea mining and militarized sonar testing. Future modelling projects that without drastic intervention, ocean warming could trigger tipping points like the collapse of the AMOC, further destabilizing global climate systems. The solution lies not in incremental policy changes but in a radical restructuring of maritime governance, including the decarbonization of global shipping, the expansion of Indigenous-led marine stewardship, and the enforcement of a global moratorium on deep-sea mining—all while centering the voices of marginalized communities whose livelihoods are most directly threatened by these changes.
