 The ocean absorbs about 25–31% of the carbon dioxide (CO2) emissions released into the atmosphere: 

Carbon sink

The ocean is the world's largest carbon sink, absorbing carbon dioxide from the atmosphere and storing it. 

Climate change

The ocean acts as a natural buffer against climate change by absorbing CO2 and excess heat from human activities. 

Carbon levels

The ocean holds 60 times more carbon than the atmosphere. 

Ocean acidification

As CO2 levels in the ocean increase, ocean acidification occurs. This can harm marine life by eating away at the minerals they use to build their shells and skeletons. 

Southern Ocean

The Southern Ocean is one of the most important carbon sinks on the planet, absorbing 40% of the human-produced CO2.
