Acid Oceans – 30% increase in acidity since Industrial Revolution

I have just read this scary paragraph in the UNCSD’s Rio 2012 Briefing Note on Oceans:

Coral Reefs and Ocean Acidification (c) Ove Hoegh-Guiderg/AFP/Getty Images“Studies have shown that since the beginning of the industrial revolution, oceans have become 30 per cent more acidic and predictions show that, by 2050, ocean acidity could even increase by 150 per cent. This would give marine ecosystems a very small period of time or adaptation, as it would represent a rate of increase that is 100 times faster than tat of any ocean acidity change experienced over the last 20 million years”.

The full document is here.
