Increasing of hydrogen ion concentration in the water. As carbon dioxide absorbed into the ocean, it react with water to form carbonic acid, a weak acid, which will breakdown into hydrogen ion and bicarbonate ion. The hydrogen ion is responsible for ocean acidification taken place in the ocean.
Why does ocean acidification is a major problem?
This video will demonstrate the problem of ocean acidification and its impact on marine organism and people who depend on marine resources.
The second video, Professor Ove Hoegh-Guldberg, a well known researcher on the impact of global warming on coral reef will explain the importance of coral reef, its role in ecosystem, and the impact of global warming.
