Global ocean acidification increase

The graph shows how the pH of global ocean waters decreased between 1982 and 2022 – this means that the ocean has become 18% more acidic over 40 years.

Playing a huge role in moderating the climate, oceans are fundamental to the functioning of our planet. Understanding more about how seawater temperatures are rising and how oceans are absorbing excess atmospheric carbon dioxide, as well as knock-on issues such as ocean acidification, is key for understanding climate change and for taking effective action.

A recent scientific paper highlights just how satellites are becoming increasingly important in providing unique information on ocean health to guide climate mitigation and adaptation efforts.
