In chemistry class, we quickly learn that acid is a dangerous substance. So, when we learn that our oceans are becoming more acidic, it follows that we assume that's not a good thing. That's a good assumption to make. We hear a lot about carbon dioxide polluting our planet these days. But what we don't hear too much is how our oceans are buffering us from the true impact, by absorbing at least half of our emissions. Not without cost, however. The chemistry of our oceans is changing, and the consequences are somewhat alarming.
