Record-breaking ocean temperatures driven by El Niño and climate change
IN · Published Aug 26, 2026
Scientists have recorded the highest global average sea-surface temperature ever measured, reaching 70°F (21.1°C) on 22 August
This milestone, reported by Europe’s Earth observation agency Copernicus, highlights the combined impact of human-induced climate change and a powerful El Niño event in the tropical Pacific. The previous record was set in March

Impact & Risks

The rising ocean temperatures pose significant risks to marine ecosystems and coastal communities. Warmer oceans contribute to sea level rise, intensify storms, and reduce the oceans' ability to absorb carbon dioxide, exacerbating climate change. Coastal areas may experience more frequent and severe weather events, while marine biodiversity faces threats from changing habitats and increased stress. These conditions could have long-term implications for global food security and economic stability in affected regions.
