'Double trouble' in acidic, warming oceans - study http://apocadocs.com/s.pl?1274546383
Acidification of the oceans means "double trouble" for marine life from corals to shellfish since it is adding to stresses caused by global warming, a study showed on Wednesday.
"The oceans are more acidic than they have ever been for at least 20 million years," according to the report by the European Science Foundation. On current trends, seas could be 150 percent more acidic by 2100 than they were in pre-industrial times.
Sea water is acidifying because carbon dioxide, released to the atmosphere from burning fossil fuels, is slightly corrosive in water. That makes it harder for creatures such as corals, lobsters, crabs or oysters to build their protective shells.... Among worrying precedents were fossil records of a leap in ocean acidity 55 million years ago that caused a spasm of extinctions of creatures living on the ocean floor, he said. That pulse may have been caused by natural releases of methane.
