Ocean carbon emissions thought to have ended previous Ice Age

By on February 25, 2015

A new study suggests that carbon dioxide from the ocean brought the previous Ice Age to an end, according to a report from BBC News. University of Southampton scientists believe that the ocean released carbon dioxide into the atmosphere which prompted rising temperatures.

Marine organisms’ shells were tested for chemical signatures that enabled scientists to determine the seawater’s acidity and its level of carbon dioxide. The study showed a correlation between high levels of carbon dioxide in the ocean and increased carbon dioxide in the atmosphere.

Researchers speculate that the warmer the oceans get, the more their ability to absorb carbon dioxide will diminish. They also concluded that the ocean’s role in the carbon cycle and climate change needs to be better understood.
