Study: CO2 “acidification” does not harm Coral

From the department of “settled science” …

Watts Up With That?

Guest essay by Eric Worrall

A study, pH homeostasis during coral calcification in a free ocean CO2 enrichment (FOCE) experiment, Heron Island reef flat, Great Barrier Reef led by researcher Lucy Georgiou has concluded that at least some Coral has the ability to regulate its own internal PH. This allows the studied coral to thrive, even in extreme acid environments.

From the conclusion of the study;

Importantly, individual nubbins exhibited near constant δ11B compositions along their major growth axis over each of the four growth periods measured, regardless of whether they were grown under treatment or control conditions (Fig. 2A and Fig. S4A). These near constant δ11B compositions equate to near constant internal pHcf (Fig. 2B and Fig. S4B), irre- spective of treatment and season and declined by less than 0.1 units per unit decrease in external pHsw (Δp Hcf =Δp Hsw= 0.067, P = 0.078, df = 36; Table…

    We know that the CO2 concentration of the oceans is going up but it would be hard to blame fossil fuel emissions for these changes.

      Do we? Where is the evidence to back that claim? How long have studies into the CO2 content of oceans being going on? (If you want to use palaeological records as evidence, please bear in mind that they will only be able to give rates of change over centuries, not the few years over a pitiful range of sites that modern studies are giving us.)

        CO2 and its ability to “Acidify” and cause supposed “global warming” emotes such ridiculous alarmist rhetoric when one understands that we currently live in s CO2 starved environment, in historical terms, and that CO2 is plant food. Period.
