What may be the broadest and longest study to date has found Canada’s Arctic Ocean is growing more acidic up to four times faster than any other sea on the planet.

Arctic Ocean acidifying faster than southern seas, study finds An international study suggests greenhouse gases are acidifying the Arctic Ocean at a faster rate than any of the world's southern seas.

And acidifying oceans threaten to wipe out the "potato chips of the sea, the mollusks called sea butterflies that flit through open water on tiny wings and feed all manner of predators.

"Evolutionary processes need to be considered when predicting the effects of a warming and acidifying ocean on phytoplankton," according to the German-led study in the journal Nature Climate Change.

Jenny Waddell/NOAA Crustaceans are far from the only sea creature to suffer under the fallout of acidifying oceans. When carbon dioxide mixes with sea water, the gas transforms into carbonic acid.

It found almost a million square kilometres of ocean had grown more acidic, including more northern waters where the effect hadn't been seen before. The study also found the entire basin was ...

The study also found the entire basin was acidifying at a rate at least three and up to four times faster than any other ocean — a speed much faster than that predicted by global emissions models.
