Acidic oceans of the future show extinction

“Today the ocean’s pH is lower than anything seen in the historical record in the past 800,000 years, scientists say. As the acidity increases, organisms such as corals, oysters, snails and urchins have trouble pulling minerals from the seawater to create protective shells. The study released Monday buttresses ecologists’ fears that such changes could ripple through entire ecosystems – and that ocean acidification could prove as consequential and catastrophic for the globe as any changes in air temperature associated with climate change.”
