ocean acidification

Marine pH decline

Ocean acidification is the ongoing decrease in the pH of Earth's oceans caused by absorption of carbon dioxide from the atmosphere.

As seawater absorbs CO₂, chemical reactions produce carbonic acid, making the water more acidic.

This process threatens marine life, particularly organisms that build shells or skeletons from calcium carbonate, such as corals, oysters, and certain plankton.

Ocean acidification is sometimes called climate change's evil twin.
