Ocean Acidification

Scientists are warning that corals, fish and other marine organisms are in danger. The more carbon dioxide from the atmosphere that dissolves in the world’s oceans, the more acidic the water is becoming. Researchers from the Alfred Wegener Institute in Bremerhaven are examining how ocean life responds to the acidification.

Some corals, for example, are unable to rebuild their exoskeletons. Fish may be less able to swim against currents. The researchers’ findings will be incorporated into the part of the UN’s Fifth Climate Assessment Report due to be made public at the end of March. For the first time, the report will feature a chapter documenting the effects of rising CO2 emissions on ocean ecosystems.
