Oceans Becoming More Acidic (and Why That’s a Big Deal)

We’ve mentioned before that higher atmospheric CO2 levels make the oceans more acidic. And that in turn is very nasty for shellfish, coral reefs, and the foundation of the ocean food supply, plankton. As this article in Science Daily reports, the consequences may be even more serious than those of global warming: The world’s oceans […]
