Key points from your link:
> About 56 million years ago, a mysterious surge of carbon into the atmosphere warmed the planet and turned the oceans corrosive. In about 5,000 years, atmospheric carbon doubled to 1,800 parts per million (ppm), and average global temperatures rose by about 6 degrees Celsius.
> In the last hundred years, rising carbon dioxide from human activities has lowered ocean pH by 0.1 unit, an acidification rate at least 10 times faster than 56 million years ago, says Hönisch.
What I cannot figure out is why if OA and global temps are dependent on atmospheric CO2, why has there not been major die offs in recent history(particularly 8k years before present. It seems to be that OA is particularly hard to study.
