Ocean Acidification Week: The ocean has become 30% more acidic over the last 250 years

As part of the Ocean Acidification Week (13-17 Sept), the Pacific Community Centre for Ocean Science (PCCOS) is highlight facts, research, and initiatives on ocean acidification.

Did you know? The ocean has become 30% more acidic over the last 250 years, and is projected to acidify by 150-200% by 2100. 

This range of change in ocean pH is unprecedented in recent geological time.
