Greenhouse Gas Poisons Oceans, Too

Carbon dioxide, long considered the primary culprit of global warming, is now facing a second serious charge: it's threatening precious marine life as well.

The burning of fossil fuels in our cars, homes, and factories have led to an ever-increasing level of carbon dioxide in the atmosphere. Most of the carbon dioxide stays in the atmosphere and contributes to global warming; one fourth of those emissions, however, are absorbed by the world's oceans.

Carbon dioxide (CO2) is soluble in water -- it dissolves in water to form carbonic acid (H2CO3). Scientists estimate that the acidity of the oceans have increased 30% since the beginning of the Industrial Revolution.

The acidity threatens the survival of coral reefs and shellfish, which in turn, can disrupt the food web of oceans.
