"WASHINGTON -- Greenhouse gases are making the world's oceans hot, sour and breathless, and the way those changes work together is creating a grimmer outlook for global waters, according to a new report Wednesday from 540 international scientists."
"The world's oceans are getting more acidic at an unprecedented rate, faster than at any time in the past 300 million years, the report said. But it's how this interacts with other global warming impacts to waters that scientists say is getting them even more worried.
Scientists already had calculated how the oceans had become 26 percent more acidic since the 1880s because of the increased carbon in the water. They also previously had measured how the world's oceans had warmed because of carbon dioxide from the burning of coal, oil and gas. And they've observed that at different depths the oceans were moving less oxygen around because of the increased heat."
