Despite the lack of a planet-warming El Niño event, global ocean temperatures were the second-warmest on record in February, behind only the El Niño year of 2024.

Ecosystem Impact
The absence of El Niño suggests that the record-breaking ocean temperatures are driven by sustained greenhouse gas accumulation rather than natural variability, which poses a severe threat to marine biodiversity through prolonged thermal stress. High sea surface temperatures correlate with accelerated coral bleaching events and the disruption of nutrient cycling, potentially transforming critical oceanic carbon sinks into net sources of atmospheric carbon.
Systemic Reality
This data indicates a fundamental upward shift in the global temperature baseline, rendering historical climate models less predictive for financial risk assessment in insurance and agriculture. The decoupling of record warmth from natural ENSO cycles will likely trigger more aggressive regulatory shifts and accelerate the transition toward decarbonization as global policy frameworks struggle to adapt to the accelerating pace of non-cyclical warming.
