Oceans Break Heat Records for 100 Days; El Niño May Push Anomaly Past 2°C

Global ocean temperatures have exceeded previous records for 100 consecutive days, with scientists warning that a strengthening El Niño in the Pacific could produce a monthly temperature anomaly above 2°C. The sustained marine heatwave signals accelerating climate change and raises risks of extreme weather, coral bleaching, and fisheries disruption. Uncertainty remains over the exact timing and magnitude of the anomaly.
