Study: Acidification From CO2 Emissions Threatens Oceans 
---------------------------------------------------------


 
A new study shows the Arctic Ocean is becoming more acidic as it absorbs
soaring carbon dioxide emissions in a shift that could imperil the
ecosystem. According to an international team of scientists the average
acidity of surface ocean waters across the globe has increased by
roughly 30 percent over the past two centuries. Experiments have shown
the acidification process could drive some species to extinction.
Researcher Richard Bellerby told the BBC: "We have already passed
critical thresholds. Even if we stop emissions now, acidification will
last tens of thousands of years," he said.
