Experts say that 400 PPM CO is making the oceans acidic, and dissolving the carbonate shells of shellfish.
This is utter bullshit. The Mesozoic shellfish below lived at 1,800 PPM CO2 – more than four times higher than current levels. Oceans are buffered by alkali rock like limestone and basalt, and can’t become acidic.
Climate experts are scoundrels who are paid to lie, while pretending to be actual scientists.
