Ocean acidification is often referred to as the “other CO₂ problem”, and is a chemical response to the dissolving of carbon dioxide into seawater.

The equation is simple: as CO₂ in the atmosphere goes up (and there was a record-breaking increase in 2013), the pH of the ocean falls, with negative impacts on marine biodiversity, ecosystems and society.
