Example of Ocean Acidification

When carbon dioxide dissolves in water, it forms carbonic acid. This decreases the pH of the water and compromises the shells and skeletal structures of marine life.

Gas absorbs more efficiently in cold water, making the Arctic Ocean particularly susceptible. Recent measurements from the Arctic show that pH levels are dropping rapidly, and it will take tens of thousands of years for the marine ecosystem to rebound.
