Ocean surface temperatures hit record high as world enters “uncharted territory,” scientists warn
Global sea surface temperatures have reached record highs for this time of year, adding to evidence that the world’s oceans are moving into what scientists describe as “uncharted territory.” Copernicus measurements show the global average hitting record levels, with analysts linking the spike to long-term ocean warming driven by greenhouse gases, alongside temporary boosts from El Niño. Researchers warn the heat can intensify marine heatwaves, harm ecosystems, and affect weather and sea level.
