The world's oceans are turning acidic due to the buildup of carbon dioxide (CO2) in the atmosphere, and scientists say the effects on marine life will be catastrophic.

“Increasing levels of carbon dioxide in the atmosphere may make Earth's oceans more acidic faster than previously thought—unbalancing ecosystems in the process. New study says: Helen Scales for National Geographic News” For tens of millions of years, Earth's oceans have maintained a relatively stable acidity level. It's within this steady environment that the rich and varied web of life in today's seas has arisen and flourished. But research shows that this ancient balance is being undone by a recent and rapid drop in surface pH that could have devastating global consequences. Read more [...]
