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
Ocean acidification is a pressing concern rising among marine scientists and environmentalists worldwide. Ocean acidification is a process in which the pH of seawater decreases, making it more acidic and harmful to the marine life that relies on it. This phenomenon is mainly due to the increase of carbon dioxide emissions in the atmosphere which are absorbed by the ocean. This causes chemical reactions that lower the pH. The problem is heightened by the ocean's limited capacity to absorb CO2, and as emissions continue to rise, the ocean is becoming more and more acidic. The impact ocean acidification has on marine ecosystems is significant. It affects the ability of marine creatures to form skeletons and shells, and can also affect the behavior and physiology of fish and other marine animals, which makes them more vulnerable to diseases and predators. In addition, ocean acidification can have ripple effects throughout entire ecosystems, like loss of biodiversity and the decline of important habitats, like coral reefs. The problem of ocean acidification is a massive, worldwide problem that needs a massive, worldwide response. Efforts are already being made to reduce carbon dioxide emissions through international agreements like the Paris Agreement, although more needs to be done to address the root cause of ocean acidification and to alleviate its effects on aquatic ecosystems. This can include but is not limited to (mainly) reducing carbon emissions, promoting sustainable fishing practices, and investing in research to better understand the impacts of ocean acidification on marine life. By taking action now, we can help preserve the health and diversity of our oceans for generations to come.
