Uh oh. If it seemed that this climate change thing couldn't get any worse, University of Chicago researchers have some bad news for you, and me, and our days at the beach: the pH of our saltwater is becoming way too acidic way too fast.
What's causing the rise?
In regular English: more CO2 equals higher acidity in our oceans.
"Of the variables the study examined that are linked to changes in ocean acidity, only atmospheric carbon dioxide exhibited a corresponding steady change," said J. Timothy Wootton, the lead author of the study and Professor of Ecology and Evolution at the University of Chicago.
What are the concerns with a pH change?
Foodchain health. A lot of fish depend on shelled animals, coral, and algae for sustenance, and a lot of people depend on fish for proper nutrition.
Ecosystem health, (e.g. coral reef bleaching [follow this link to a ton of interesting empirical research]).
What's the solution?
Not pumping CO2 into the air in such immense quantities.
