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?

Acidity Rising in The Indian Ocean
Since 1980, there has been a steady decline in The Indian Ocean's pH level, causing it to be more acidic. Going from 8.2 pH in 1980 to 7.94 in 2025. It has been declining at a rate of 0.015 every decade. This could pose problems in the future to any marine wildlife that will live there. Does anyone have a reason for this?
