Ocean acidification is like global warming’s sad, ignored twin. It results, like climate change, from human emissions of greenhouse gases, much of which, we know, are absorbed into the sea, lowering the water’s pH level.

Rapid carbon emissions 252 million years ago wiped out the majority of the planet’s species. So it’s kind of a big deal.
