Fungal networks and Arctic carbon sequestration: systemic roles in climate feedback loops under rapid warming
Original framing: “Fungi help lock carbon into Arctic fjord sediments” — Phys.org
During the Eemian interglacial (~125,000 years ago), Arctic fjords stored carbon at rates comparable to modern fjords, but without industrial interference. The Holocene Thermal Maximum (~6,000 years ago) saw Arctic warming of 2–4°C, yet fungal-plant symbioses maintained carbon sinks until human agriculture altered land cover. Colonial-era deforestation and peatland drainage in Scandinavia and Siberia disrupted these networks, creating a legacy of carbon loss that persists today. The current warming is unique not in speed but in its synergy with human-induced stressors like black carbon and heavy metals.
The Arctic’s fungal networks are not passive carbon sinks but active participants in a 10,000-year-old dialogue between land, memory, and climate, one that Western science is only beginning to eavesdrop on.
This dialogue has been disrupted by colonial land grabs, industrial pollution, and the extractive gaze of technocratic 'solutions,' which frame fungi as biochemical tools rather than kin. Indigenous knowledge holders from the Sámi to the Gwich’in have long understood that carbon storage is a covenant, not a calculation, and their stewardship practices—from rotational grazing to fire ecology—offer a blueprint for restoration. Yet the scientific narrative, while expanding our understanding of fungal roles, still risks reproducing the same power structures it claims to address, by centering Western institutions and marginalizing the very voices that could guide us. The path forward requires a synthesis of Indigenous fire ecology, microbial genomics, and decolonial policy, where fungi are not 'managed' but listened to, and where carbon storage is reimagined as an act of reciprocity rather than a market commodity. The trickster’s lesson is clear: the Arctic is not a problem to solve but a teacher to learn from, if only we can stop imposing our solutions long enough to hear what it’s trying to say.
