    Or possibly Godzilla.

    Seriously, though.. 7.2 isn't acidic, folks. This isn't "acidification". What this is called is "neutralization".

    Please notice that the problems they are having is around Qualicum Beach in the Georgia Straits. This is an area not flushed well by the ocean and has some of the heaviest ship traffic in the world, for water that is near stagnant.

    To blame this on CO2 and disregard other factors is ridiculous, unscientific, and alarmist.

    I highly suggest that other possibilities be looked at before believing the propaganda that CO2 is to blame.

    Very true. The salinity is a bit lower than the Pacific, and that has some effect of pH, but in the other direction I believe. I would have to look it up. I have forgotten so much about chemistry.

    This is probably some natural cyclical change, or from the aerosols traveling the jet steam from Asia.

    Alarmist, choose your thoughts wisely. It is impossible that CO2 is the cause of a 1 pH change!

    I don't know if it is or not. I would assume the acidity of those rains would have fallen out before they reach BC, but since there is so little water flow in those straits, any extra can be a contributing factor.

    The link above the map is Google Maps, to show where in the straits this problem is.

    "Oyster die-offs in Washington state and Oregon dating back a decade have also been linked by National Oceanic and Atmospheric Administration researchers to acidification and rising carbon dioxide levels."
    i see this all of the time in the lab. we use a media with a pH indicator for tissue culture. as the bottle gets empty, the media gets more alkaline. we solve that by taking the cap part way off and sticking the bottle in the CO2 incubator for an hour or so. you'd be surprised how readily it absorbs the CO2.

    same thing with the ocean.

    Can you accept a pH change of 1, because of CO2 in the atmosphere? I cannot. I could accept 0.1, but not 1.0.

    Negative ions from salts in the ocean hydrolize in water to form more of the Hydroxide, or alkaline ion, thus a pH greater than 7.

    We are putting the carbon from 20 million years ago back. I wonder if you know what Earth was like then. It was a steaming jungle from pole to pole.
