Ocean acidification has scary potential, but experiments like this one don't scare me too much. I'm willing to bet human infants born into what these scientists would forecast our world to look like in 84 years, given no time to adapt, would also survive at lower rates.

Considering the harvest rate in today's crab fisheries, if you tell me crab productivity will be "less" in 84 years, I'll take that as great news. If we keep going the way we're going, there won't be much left in the ocean by 2100, period.

I complain a lot that mankind suffers from a tragic lack of foresight. In this particular case (as with salmon), I think we could stand to focus more on the state of the species TODAY. The status quo in our marine fisheries is a far greater, much more immediate threat to our iconic marine species, and it's something we actually CAN control in the near term.
