Ocean acidification crosses “planetary boundaries”

Ocean acidification, a significant threat to marine life, is reportedly worsening and has now crossed critical planetary boundaries. This phenomenon, driven by the absorption of excess carbon dioxide from the atmosphere, is altering ocean chemistry at an unprecedented rate. The increasing acidity poses severe risks to shell-forming organisms, coral reefs, and the entire marine food web. These changes are impacting biodiversity and the vital services oceans provide to the planet.

This matters because the health of ocean ecosystems is crucial for global food security, climate regulation, and the livelihoods of billions of people.
