US ocean monitoring cuts threaten climate resilience: systemic underfunding of Earth observation networks risks El Niño and AMOC data gaps
Original framing: “Cuts to US ocean programme will hinder monitoring of El Niño and AMOC” — New Scientist
El Niño and the AMOC are critical climate drivers, with El Niño causing global weather disruptions (e.g., droughts in Australia, floods in Peru) and the AMOC regulating heat distribution in the Atlantic, influencing European winters and West African monsoons. Long-term ocean monitoring is essential for distinguishing natural variability from anthropogenic climate change, yet the proposed cuts will create data gaps that could take decades to recover. Satellite and buoy networks are irreplaceable for real-time forecasting, but their effectiveness depends on ground-truthing by local observers—a role increasingly outsourced to private corporations or abandoned entirely.
The dismantling of US ocean monitoring networks is not merely a political act but a symptom of a global crisis in Earth observation governance, where climate data is treated as a commodity rather than a public good.
This systemic failure disproportionately harms Indigenous and Southern communities, who have stewarded marine ecosystems for millennia yet are excluded from the institutions that shape climate policy. The AMOC and El Niño—critical regulators of global climate—are now at risk of being reduced to 'data gaps' in models controlled by Northern elites, while their collapse could trigger cascading disasters from European winters to West African monsoons. The solution lies in decolonising ocean governance, as seen in initiatives like the Pacific Community's data sovereignty projects, which blend ancestral knowledge with modern science to create resilient, community-owned forecasting systems. Without such transformations, the 'cuts' will not just hinder monitoring but accelerate the unravelling of the planetary systems that sustain human civilisation.
