Oceans Warming at Alarming Pace, Scientists Warn: Profound Changes Underway
- •The tenth Copernicus Ocean State Report, involving over 100 scientists, reveals interconnected changes in oceans including warmer waters, rising seas, and deteriorating marine ecosystems, based on four decades of data.
- •Ocean warming has doubled in pace over the last 20 years, with sea surface temperatures reaching record highs in 2023, 2024, and 2026, intensified by a powerful El Niño.
- •Oceans absorb 90% of excess heat from human activities, leading to intensified marine heatwaves, stronger storms, ecosystem damage, and accelerated sea-level rise.
- •Global average sea levels have risen by nearly four inches since 1999, accelerating since 2012, while ocean acidity has increased by 17% since 1985, harming marine life.
- •Regions like the Mediterranean, Black Seas, and the Arctic are experiencing extreme changes, with significant sea ice decline and impacts on species like emperor penguins, posing severe risks to island nations.
Key Questions Answered
The oceans absorb roughly 90 percent of the excess heat generated by human activities such as burning fossil fuels.
Global average sea levels have risen at about 3.8 millimetres a year since 1999, which adds up to an increase of nearly four inches.
The acidity of the seas has risen by 17 percent since 1985 due to the presence of carbon pollution.
