Death knell for...benthic marine organisms? Probably. Ocean acidification rates are highest in over 65 million years.

Past constraints on the vulnerability of marine calcifiers to massive carbon dioxide release

Andy Ridgwell & Daniela N. Schmidt

Increasing concentrations of carbon dioxide in sea water are driving a progressive acidification of the ocean1. Although the associated changes in the carbonate chemistry of surface and deep waters may adversely affect marine calcifying organisms2, 3, 4, current experiments do not always produce consistent results for a given species5. Ocean sediments record past biological responses to transient greenhouse warming and ocean acidification. During the Palaeocene–Eocene thermal maximum, for example, the biodiversity of benthic calcifying organisms decreased markedly6, 7, whereas extinctions of surface dwellers were very limited8, 9. Here we use the Earth system model GENIE-1 to simulate and compare directly past and present environmental changes in the marine realm. In our simulation of future ocean conditions, we find an undersaturation with respect to carbonate in the deep ocean that exceeds that experienced during the Palaeocene–Eocene thermal maximum and could endanger calcifying organisms. Furthermore, our simulations show higher rates of environmental change at the surface for the future than the Palaeocene–Eocene thermal maximum, which could potentially challenge the ability of plankton to adapt.

Looks like South Carolina has joined the madness as well. They're trying to legislate equality of issues in the class room. Science is not democratic, it is meritocratic.

It's so ludicrous, that SC actually appears to be consulting horoscopes:
That there are a variety of climatological, meteorological, astrological, thermological, cosmological, and ecological dynamics that can effect world weather phenomena and that the significance and interrelativity of these factors is largely speculative;
Emphasis mine...unbelievable.

Perhaps they will take a page from Tonnington's Big Book-'O-Spin that attempts (poorly I might add) to legitimize the voodoo science that is the AGW movement today.

You wouldn't know science if it punched you in the face.

Care to debate this topic formally? With references, and the works? You know, like actual science debates? I'd chew you up and spit you out. I understand if you're not up to it. It doesn't seem like you have much experience with formal science. Blog science appears to be your style (no substance, all rhetoric.)

I'd say there's a slim chance of you accepting my challenge...

Australopithecine - That's an awfully big word for you..... Do ya need a wee rest now or maybe you want to debate the suitability of journalists and zoologists on the issue?
