Ocean acidification: the other CO2 problem

by Andrew Dickson
Scripps Institution of Oceanography, UCSD

Abstract

The continuing increase in atmospheric CO2 resulting from man's activities is not only changing our climate, it is causing changes in the oceans' chemistry. As the amount of CO2 taken up by the oceans increases, it causes an increase in the oceans acidity and a concomitant reduction in the carbonate ion concentration. This has profound implications for a wide variety of carbonate-forming marine organisms who are finding it harder to form biogenic calcium carbonate. Ultimately this could lead to the demise of many calcifying marine species with, as yet, unknown consequences for marine ecology.
