UN Warns of 'Severe' Stress on Oceans as Sea Level Rise Doubles in 10 Years

The Alarming State of Ocean Health
The world's oceans are under 'severe and accelerating' pressure from human activities, with the rate of sea-level rise doubling in just 10 years, according to a damning assessment from the United Nations. The UN's third World Ocean Assessment, which reflects the work of nearly 600 scientists from 86 countries, paints a dire picture of the health of the planet's oceans.
Key Findings: Sea Level Rise and Ocean Heat
The report's key findings include:
Sea levels continue to rise at an increasing rate, from 2mm a year prior to 2015 to 4.3mm a year in 2023.
16% of the increase in global ocean heat since 1955 occurred after 2018.
The greatest relative warming has been observed in the Atlantic Ocean and the southern parts of the Indian and Pacific Oceans.
The Data Analysis: Quantifying Ocean Pollution
The report also calculated that 52.1m tonnes of plastic a year enter the ocean, contributing to the 24.4tn microplastic particles that impact more than 4,000 marine species.
The Impact Analysis: Consequences of Inaction
The ocean, which covers more than 70% of the planet, plays a central role in regulating climate, maintaining biodiversity, and providing food, minerals, and energy for humans. However, it has already absorbed 90% of the excess heat and 30% of the carbon dioxide released into the atmosphere by the burning of fossil fuels.
The Prediction: Urgent Action Needed
The report's findings serve as an 'urgent wake-up call' to governments to protect the ocean from deep-sea mining and industrial fishing. The UN secretary general, António Guterrez, emphasized the need for 'urgent global collaboration' to protect marine ecosystems, saying, 'We cannot keep treating the ocean as limitless.'
