Ocean acidification to blame for slowing coral reef growth, says new study

The video explains how CO2 absorption by oceans forms carbonic acid, increasing ocean acidity. Over two centuries, ocean pH dropped from 8.2 to 8.1, a 26% acidity increase. Coral uses carbonate ions for skeletons, but carbonic acid reduces these ions, affecting coral growth. A study in the Great Barrier Reef showed coral grows faster in less acidic water. Protecting coral reefs is crucial as they host diverse marine life.
