The other CO₂ problem
CSIRO contributing to some more excellent global reports on the impacts of ocean acidification on marine biodiversity. Well worth a read.

Where would we be without the ocean? Swimming, surfing, snorkelling would be tough, not to mention all the yummy food we’d miss. But it has also played a more important role in all of our lives; fulfilling the noblest of causes.
For many years the ocean has been on the front line in the fight to slow down climate change, absorbing around a quarter of the carbon dioxide we produce. The problem is that the scars of this attack are beginning to show.
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.
