Oceans Acidifying Fastest in 300 Million Years

[donsutherland1]

From Bloomberg.com:

The Earth’s oceans may be acidifying faster than at any point during the last 300 million years due to industrial emissions, endangering marine life from oysters and reefs to sea-going salmon, researchers said.

The scientists found surging levels of carbon dioxide in the atmosphere forced down the pH of the ocean by 0.1 unit in the last century, 10 times faster than the closest historical comparison from 56 million years ago, New York's Columbia University, which led the research, said yesterday in a statement. The seas absorb CO2 from the atmosphere, forming carbonic acid. The lower the pH level in the seas, the more acidic they are.

For anyone who is interested, thats about 5% of the way from physiologically normal toward the pH of the primary lysosome...at which point autolysis (self digestive death) of cells occurs..........assuming it doesn't kill them in some other (more indirect) way first.
