Whoops, my bad, changed the title a bit. Now fixed.

Rob - When using the term "acidic water", do you mean water with a pH lower than 7.0?  Some commentators might try and make hay if you are using the word acidic to mean just a lower pH (acidification).

Steve - quite right. I've changed the wording to 'acidified' or 'acidification'. But for many species it may as well be below 7.0, they're still going to be stuffed.

Kind of surprises me this hasn't gained more traction with the mainstream media - this is potentially catastrophic news. Where the frack do people think their food comes from? These changes in ocean chemistry cannot be fixed by humans, and won't be fixed by nature for hundred of thousands to millions of years.

Rob,

I think the "problem" with the OA story is that it's NOT controversial. There's very little source for confusion about the degree or cause for decreasing pH. So, no coverage!

What may be needed is more harping on the consequences.

Yeah, I guess you're right Neal. I'll keep 'harping' on about it, but try not to sound like a nag.

Rob,

As usual, this post is excellent, and you need to keep harping on about it. Sure, as Neal says, there is very little source for confusion on OA. I would in fact argue there is very little source for confusion on AGW, but that doesn't stop the deniers pretending there is. SkS has a huge following among climate scientists, and we need aticles like this to remind them to harp on about it too!

Your piece reads well, and I would make just one suggestion. In paragraph 3 it was not immediately clear to me that you were describing the same experiment that you discuss more fully under "One fish, two Fish". I recommend appending the following line, or something similar, to paragraph 3 in order to indictate that it is a summary of what follows:

Baumann (2011) show that larvae survival in one fish species drops with increased levels of CO2 (figure 1). Survival rates plummeting some 75% under a scenario with 1000ppm (parts per million) of atmospheric CO2. And Frommel (2011) discovered considerable tissue damage and necrosis (dead tissue) in fish larvae of another species exposed to higher levels of CO2 than the present day. In the high CO2 experiments, this damage to internal organs was so extensive it lead to the death of afflicted larvae. Each of these studies is discussed in detail below.

Thumbs up!
