Acidification caused by carbon emissions could bring some oceans to a tipping point.
By Peter N. Spotts | Staff writer/ December 18, 2008
Parts of the world’s oceans appear to be acidifying far faster than scientists have expected.
The culprit: rising levels of carbon dioxide in the atmosphere pumped into the air from cars, power plants, and industries.
The Southern Ocean represents one of the most high-profile examples. There, scientists estimate that the ocean could reach a biologically important tipping point in wintertime by 2030, at least 20 years earlier than scientists projected only three years ago. Among the vulnerable: a tiny form of sea snail that serves as food for a wide range of fish. …
