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
I think humans should be more concerned with ocean acidification. Ocean Acidification is when the ocean absorbs CO2 from the atmosphere causing the ocean water to become more acidic. Everyone can reduce greenhouse emissions and prevent ocean acidification through small steps. For example, whenever our family members drive, they release greenhouse gases such as methane and CO2 into the atmosphere. Ocean acidification is extremely dangerous to calcifiers because it lessens carbonate ions. The release of CO2 lessens the pH of water making the ocean more acidic. Ocean Acidification can lead to the extinction of the oceanic creatures that depend on calcium carbonate.
