In addition to the famous impacts of atmospheric carbon on global warming, there is an equally worrisome effect of carbon dioxide on the oceans: ocean acidification (or OA for short). Here at I2SEA we have a series of resources about OA, including Our Acidifying Ocean, which is an introductory activity and virtual lab (note: now mobile compatible!).
A student suggested that we start a conversation topic about OA, and here it is! Have you heard about Ocean Acidification? If so, are you worried about it? How do you think we can best raise awareness about it among your fellow students and the general public? Have you seen particularly good links or films about OA that you would like to share? What are you doing to address the problem?
Ocean Acidification >
CO2 not only raises the temperature,but also harms marine animals
Carbon Dioxide produced by humans and burning fossil fuels not only is a greenhouse gas which is one of the leading reasons for global warming but it also is raising the ph of ocean water. This is because when the carbon dioxide mixes with the ocean water it reacts and lowers the ph of the water which is why it becomes acidic. 1/4 of the carbon dioxide that is currently being produced is being absorbed into the ocean water making it more acidic which is negatively impacting ocean life such as corals, crabs, oysters, and urchins which is killing them but also taking away food sources from predators that eat these animals.
I agree with your statements and would like to add that the animals, such as corals, crabs, oysters, and urchins, are affected very badly by more acidic ocean water. The more acidic water causes their shells and skeletons made from calcium carbonate to dissolve. Their shells will dissolve faster with the more acidic ocean water.
