Operating as a carbon dioxide sink, unfortunately, means the oceans are gradually (or frighteningly fast, considering the scale) becoming more acidic. On the 0-14 pH scale, 7 is neutral; the oceans on average have dropped from 8.2 to 8.1 (it’s a logarithmic scale, so that’s a much bigger shift than it looks). So they’re not going to eat the skin of bathers’ bones–yet!–but to the marine life adapted to 8.2, things don’t feel quite right at all. Continue reading The Puget Sound Experiment in Acidification
