A recent study released by the secretariat of the Convention on Biological Diversity (CBD) in collaboration with the UNEP World Conservation Monitoring Centre (UNEP-WCMC) at the Bella Convention Centre in Copenhagen has revealed that oceans are becoming more acidic at a rate 100 times faster than any change in acidity seen in the past 20 million years. This rapid increase in acidity is giving little time for biological systems to adapt evolutionarily. The study explains that oceans currently absorb around one quarter of the carbon dioxide emitted into the atmosphere from human activities such as burning fossil fuels and deforestation. Without this absorption, atmospheric CO2 levels would be much higher, leading to more pronounced effects of global climate change. The absorption of atmospheric CO2 has caused the oceans to become more acidic, with predictions indicating a potential 150 percent increase in ocean acidity by 2050. Ocean acidification is considered irreversible for thousands of years, and urgent action is needed to reduce global CO2 emissions to prevent significant damage to ocean ecosystems. Ahmed Djoghlaf, executive secretary of the convention, emphasized the importance of integrating this issue into the global climate change debate in Copenhagen. A study by the CBD highlights the alarming ecological scenarios and adverse impacts of ocean acidification on marine biodiversity, drawing on over 300 scientific sources. The research reveals that as ocean acidification continues to rise, a significant portion of cold water corals, which serve as important habitats and food sources for commercial fish, will be at risk of being in contact with acidic waters by the year 2100.
