from National Geographic News
Increasing levels of carbon dioxide in the atmosphere may make Earth's oceans more acidic faster than previously thought—unbalancing ecosystems in the process, a new study says.

The research also revealed the corrosive effect of acidic oceans could trigger a dramatic shift in coastal species and jeopardize shellfish stocks. "The increase in acidity we saw during our study was about the same magnitude as we expect over the course of the next century," said study co-author Timothy Wootton, a marine biologist from the University of Chicago.
