Climate Reality reports: Our oceans are an incredible carbon sink — they absorb about 25 percent of the carbon dioxide humans produce every year. But this is changing sea surface chemistry dramatically: when carbon dioxide is absorbed by the ocean, it dissolves to form carbonic acid. The result, not surprisingly, is that the ocean becomes more acidic, upsetting the delicate pH balance that millions and millions of organisms rely on.

Since the Industrial Revolution, our seas have become about 30 percent more acidic, a rate not observed in 300 million years. This has a wide range of consequences for marine ecosystems, as well as for the billions of people who depend on the ocean for food and survival. [Continue reading…]
