Sea Levels Rise Multiple Times Faster Due to Human Activity

Several of the world’s oceans are now facing unprecedented severe pressure due to human activity. A new report led by the United Nations (UN) reveals that the rate of sea level rise has increased drastically over the past decade, triggering a global push to immediately limit the impact of pollution and climate change. According to the World Ocean Assessment III (WOA III) document, the pressures experienced by marine ecosystems are cumulative. The major factors worsening this condition include massive pollution and the exploitation by large-scale industrial fishing. WOA III itself is the only integrated global assessment covering the environmental, economic, and social aspects of the world’s oceans. The report, compiled by more than 650 experts from dozens of countries, evaluates the condition of the oceans over the 2021-2025 period. The findings underline that human activity has caused widespread loss of biodiversity and placed an extreme systemic burden on ocean functions. One of the most crucial points in the WOA III findings is the acceleration of sea level rise. Data shows that before 2015, the average increase was at 2 millimetres (0.08 inches) per year. However, that figure surged sharply to 4.3 millimetres per year in 2023. Beyond the rise in sea levels, ocean temperatures have also reached a critical point. The study found that approximately 16% of the total increase in ocean heat content since 1955 occurred in a short period, specifically from 2018 to the present. This indicates increasingly accelerated global warming in marine regions. UN Secretary-General António Guterres issued a stark warning regarding these findings. He asserted that humanity’s paradigm towards the ocean must change immediately for the survival of future generations. ‘We cannot continue to treat the ocean as an unlimited resource. Urgent global collaboration is needed to protect marine ecosystems,’ Guterres stressed. He added that the world must build a new relationship with the ocean based on science, framed by international law, and built upon shared responsibility across nations and sectors. Without tangible action, the earth’s life-support system risks permanent damage.
