Rapid Ocean-Acidification Threatening Aquatic Ecosystems
March 22nd, 2012 | Posted by in Eco-FriendlyResearchers say human beings are playing a guilty party role in the heightened CO2 levels that is resulting ocean acidification. Ecosystems transforms according to general climate conditions and the change may distract or make organisms extinct. Columbia University's researchers
States that carbon dioxide emission have lowered the ocean's pH levels at a rate unparalleled in at least the last 300 million years of our planet's history. Excess CO2 in the atmosphere is absorbed by the seas, where it is converted to carbonic acid, which dissolves the carbonates needed by some organisms that boost up the ocean acidification at an unbelievable rate. The higher levels of carbon dioxide in the atmosphere have lowered the pH of the ocean by 0.1 units in the last century. Researchers says that "The current rate of CO2 release stands out as capable of driving a combination and magnitude of ocean geochemical changes potentially unparalleled in at least the last 300 million years of Earth history, raising the possibility that we are entering an unknown territory of marine ecosystem change."
