The biggest extinction event in planetary history was driven by the rapid acidification of our oceans, a new study concludes. So much carbon was released into the atmosphere, and the oceans absorbed so much of it so quickly, that marine life simply died off, from the bottom of the food chain up.
That doesn’t bode well for the present, given the disturbingly similar rate that our seas are acidifying right now. Parts of the Pacific, for instance, are already so acidic that sea snails’ shells begin dissolving as soon as they’re born.
Just another one of those observable effects of that human civilization is having on our planet.
Note: these are denied utterly and completely by the GOP.
