    No More Speculation: Scientists Prove Ocean Acidification is Already Underway
    While concerns over ocean acidification are not new, a recent study provides more concrete evidence than ever before that the process has already begun. Australian scientists found that shells of the microscopic, amoeba-like organisms called foraminifera, which exist by the billions in oceans around the world, have become significantly thinner since the Industrial Revolution.

    The study, published in Nature Geoscience, is the first to look specifically at acidification and pin it to greenhouse-gas pollution, which is driven especially by the invisible product of burning oil, gas and coal. “It is the invasion of anthropogenic (man-made) CO2 that is causing this particular source of acidification,” said co-author William Howard [AFP].

    The research team compared newer shells of Globigerina bulloides, a species of foraminifera, with shells of the same species that had sunk hundreds of years earlier; the modern shells were found to be 30 to 35 percent lighter than older specimens of about the same size. The older shells predate the industrial age, when CO2 levels started rising and the acidity of the ocean, caused by the absorption of the gas, began to increase…. As ocean acidity increases, the saturation levels of carbonate minerals in the water decreases, making it more difficult for organisms to precipitate out the carbonate for their shells [The New York Times].

    Interesting. Thanks.

    I'm not a scientist but it really is pretty obvious that if you put chemicals into the water via runoff or any other measure you will be creating an unstable enviroment for life.

    More like a reality. I'll work on getting some pictures of what "burn down" on the fields looks like in the streams this summer. When you see dead fish and birds scattered through the water it is pretty obvious what is happening to the enviroment we live in.

    Your previous post actually said it better, we know this, we have known this, and we have been doing work to cut back. However, if you want reality here it is:

    The most acidic substances are naturally occurring chemicals which go in cycles between the land and sea through volcanic movements and continental drift. The reason this issue calmed down was because we had discovered that much of our efforts to correct it was wrong, we were cutting the natural acidic quality that was suppose to happen. Again, the biggest problem with environuts, they are ignoring the fact that our planet destroys itself to keep life evolving. We evolved as a result of one of the most massive extinctions, not in spite of it. If the environment was always "balanced" as the envirnuts want then nothing would change, the simple law of nature and existence would be broken.

    Serious question; Why do you hate the enviroment?

    Well if acidification is occurring and that is BIG if, acid loving plants will thrive. Hell and ain't all you AGW nuts also adherents to evolution theology. What no faith in the survival of the fittest?

    Not really, no.

    Well..except in the case of cockroaches, of course.

    They'll be around long after we're gone, I suspect.

    Not a big if at all. It has been measured. Read the articles.
