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?

Rising Ocean Acidification Levels
Our ocean is increasing in acidity, and that is because carbon dioxide is entering our waters. When that carbon dioxide enters the ocean, it creates carbonic acid. The carbonic acid leads to a decrease in pH and an increase in acidity. This has a huge impact on shelled marine organisms, as they grow slower and develop weaker shells. Animals, such as coral and mussels die off faster, or are more vulnerable to predators when still alive. We also eat shellfish too, which could affect people's jobs and diets. Its a sad truth but by reducing our carbon emissions, it'll help our shelled friends grow and thrive.
