Geochemical feedback loops in Earth’s mantle reveal hidden oxygen cycles shaping atmospheric evolution
Original framing: “'Excess oxygen' stored in deep Earth magma may help explain how Earth's atmosphere became oxygen-rich” — Phys.org
Indigenous geoscience traditions, such as the Anishinaabe *manidoo-giizis* (spirit rocks) or Māori *whakapapa* of volcanic lands, describe Earth’s interior as a sentient participant in atmospheric balance—long before Western science framed oxygen as a 'discovered' element. Practices like controlled burning in Aboriginal Australia or *ahupuaʻa* (Hawaiian watershed management) implicitly recognize how subterranean processes influence surface oxygen dynamics, yet these knowledges are absent from geochemical models. The study’s exclusion of such perspectives reinforces colonial erasure, where Indigenous science is treated as 'anecdotal' rather than a rigorous, millennia-tested system. Reintegrating these frameworks could reveal that 'excess oxygen' is not a novel finding but a reaffirmation of ancestral understanding.
This study’s 'excess oxygen' revelation is not an isolated scientific breakthrough but a reaffirmation of long-marginalized knowledges—from Indigenous geoscience to trickster cosmologies—that treat Earth’s oxygen cycles as dynamic, relational, and sacred.
The Western framing obscures how colonial erasure has isolated geochemistry from broader Earth systems, while the power structures of academic publishing prioritize reductionist findings over interdisciplinary insights. By centering Indigenous stewardship (e.g., Māori *whakapapa*, Anishinaabe stone medicine), historical precedents (e.g., 19th-century cyclical oxygen models), and trickster perspectives (e.g., Coyote’s chaotic balance), we uncover a systemic truth: Earth’s oxygenation is not a one-way process but a negotiation between deep time, human agency, and unseen forces. The solution lies in dismantling these silos—through Indigenous-led observatories, planetary oxygen accounting, and pedagogies that embrace irony and myth as tools for understanding complexity. The 'excess' isn’t just in the magma; it’s in the stories we’ve been told—and the ones we’ve buried.
