Copernicus report finds oceans warming rapidly
The tenth Copernicus Ocean State Report, compiled by more than 100 international scientists, shows oceans are absorbing about 90% of excess heat from fossil fuel use and warming at an accelerated pace. The rate of ocean warming has doubled over the past 20 years, with sea surface temperatures hitting record highs in 2023, 2024 and 2026 and a record 23 zettajoules of additional heat absorbed last year. Consequences include more frequent marine heatwaves, stronger storms, accelerated sea level rise (about 3.8 millimeters per year since 1999), a 17% increase in acidification since 1985, and acute regional stresses in the Arctic and Mediterranean.
Oceans set new heat records and are driving faster sea level rise
