The changing seas

There are 3 comments on the The Star Online story from Sep 2, 2013, titled The changing seas. In it, The Star Online reports that:

Growth disrup ter: When oceans absorb increasing levels of carbon dioxide from the air, sea water turns acidic and this disrupts the formation of calcium-based shells, such as those of mussels and oysters.

The science deniers aka whitewashers don't deal with this:

RAPIDLY rising carbon dioxide levels in the atmosphere are causing a potential catastrophe in our oceans as they become more acidic, scientists have warned.

Hans Poertner, professor of marine biology at the Alfred Wegener Institute in Germany, and co-author of a new study of the phenomenon, said:“The current rate of change is likely to be more than 10 times faster than it has been in any of the evolutionary crises in the earth’s history.”

Sea water is naturally slightly alkaline, but as oceans absorb carbon dioxide from the air, their pH level falls gradually. Under the rapid escalation of greenhouse gas emissions, ocean acidification is gathering pace and many forms of marine life – especially species that build calcium-based shells – are under threat.

Poertner said that if emissions continue to rise at “business as usual” rates, this would be potentially catastrophic for some species. Acidification is just one of a broader range of the problems facing the oceans and the combination of different effects is increasing the threat. Poertner said:“We are already seeing warm water coral reefs on a downslide due to a combination of various stressors, including (rising) temperature. Ocean acidification is still early in the process (but) it will exacerbate these effects as it develops and we will see more calcifying species suffering.”

But God will intervene before it gets too toxic to support life...dontcha know anything, truthist?
