worse than we thought – acidity of Great Barrier Reef!

Waters around the Great Barrier Reef are becoming acidic at a higher-than-expected rate.

Professor Malcolm McCulloch of the Australian National University said the findings were worrying. It appears this acidification is now taking place over decades rather than centuries as originally predicted, he said.

Researchers studied a type of reef coral called porites off Cairns and found pH levels were falling faster than previously thought, meaning acidity levels were increasing. This new data on the Great Barrier Reef suggests the effects are even greater than forecast, Professor McCulloch said.
