Polar Oceans Transformed as Warming Melts Ice Habitats: Research
The report says the ocean absorbed 23 zettajoules of heat in 2025 and Arctic sea ice has declined by nearly half a million square kilometres a decade.
- On Wednesday, the 10th Copernicus Ocean State Report documented record ocean heating, rising sea levels, and increased acidity, delivering its 'starkest warning yet' about profound changes in the world's seas.
- Oceans absorb roughly 90% of excess heat from fossil fuels, with the warming rate doubling over 20 years and an additional 23 zettajoules absorbed last year, setting a ninth consecutive record.
- In the Mediterranean and Black Seas, record-breaking marine heatwaves in 2024 lasted more than 30 days, driving temperatures more than 8.3 degrees Fahrenheit above average and placing regions under 'intense pressure.'
- Ocean acidity increased by around 17% since 1985, threatening shell-building animals like oysters and corals, while global sea levels rose by an average of 3.8 millimetres annually between 1999 and 2025.
- Pierre Bahurel, Director General of Mercator Ocean International, emphasized the need for sustained monitoring, stating, 'It is our responsibility to build the permanent capacity to anticipate this transformation.
