As fossil fuel emissions increase, so does the amount of carbon dioxide oceans absorb and dissolve, lowering their pH levels. "As pH...

Instead they are booming - and fighting global warming. For hundreds of millions of years, marine creatures of all shapes, sizes and descriptions have gone about the daily business of converting calcium ions dissolved in seawater into the hard shells and skeletons that are so reminiscent of a trip to the seaside.
