New paper finds corals and molluscs transplanted to CO2 vents calcify and grow faster than normal

A paper published in the September 2011 edition of Nature Climate Change finds that corals and molluscs transplanted to 'acidified' areas along CO2 vents in the Mediterranean were surprisingly "able to calcify and grow at even faster than normal rates when exposed to the high CO2 levels projected for the next 300 years." To add the requisite alarmist spin for publication in Nature, however, the scientists returned to the laboratory where they cranked up the 'acidification' along with heat to find they could then decrease calcification slightly.

  1. It's a post normal thing, if your actual honest to God observations don't match the presupposed conclusion, change the damn experiment until it does or...........fix the data/results, ask Mike and the 'nature trick boys'.

  2. MS,
    Check this PP presentation by Willie Soon. Scroll down to the section on ocean "acidification" and look at the studies using extremely high CO2 levels.


    “Most of these experiments used
    semi-continuous cultures, in which
    the carbonate system was modified
    by the addition of acid and/or base to
    control pH.” —Debora Iglesias-Rodroguez et al. (2008)

    “[Szmant] faults previous lab studies
    because they used hydrochloric acid,
    not carbon dioxide, to lower the pH of
    the water in the calcification studies.”
    — Elizabeth Pennisi (2009) quoting Alina Szmant, a coral ecologist

  3. The title and the abstract seem to be schizophrenic. The title and last sentence of the abstract announce bad news, while the abstract includes the following: "... Here, we show that corals and molluscs transplanted along gradients of carbonate saturation state at Mediterranean CO2 vents are able to calcify and grow at even faster than normal rates when exposed to the high CO2 levels projected for the next 300 years."

    The last sentence says, "Our combined field and laboratory results demonstrate that the adverse effects of global warming are exacerbated when high temperatures coincide with acidification."

    However, the abstract does not tell us how growth under high-temps-and-high-CO2 compares with growth under current-temps-current-CO2 conditions.

    While this is uninformative, it certainly begs one to read the full paper.

  4. Link to paper.

  5. Check out the NOAA website and see Jane Lubchenco demonstrate how sticks of chalk dissolve in acid, to demonstrate ocean acidification....

  6. Anonymous, again, read this and look at studies done with shellfish in high CO2 conditions.


  7. Experiments at Southampton University several years ago 'proved' that increased CO2 leads to acid dissolved shells. Later it was discovered that pH of the sea water was increased by adding hydrochloric acid.

    A big cheat to get their version of the truth.

  8. Slimething:
    Great presentation, excellent graphics and highly useable. I hope you didn't think I believed Lubchenco!!
