Fearing for krill (and penguins, whales, etc)

The krilling fields: study fears catastrophe in Antarctic food chain | theage.com.au

From the report:

Captive-bred krill at the Australian Antarctic Division developed deformities and lost energy when they were exposed to the greenhouse gas at levels predicted globally for the year 2100.

The damage meant that the krill were unlikely ever to breed, a University of Tasmania investigator, Lilli Hale, said yesterday.

Polar life, from tiny seabirds through penguins and seals to whales, depend for food on Antarctic krill, Euphasia superba.

I see that Tim Blair today has a short post up linking to a different ocean acidification story, pretty much as if it is the first time he has heard of the issue. I have said it before, but I don't understand why it is a topic that attracts very intermittent coverage, as it will happen whether or not the planet heats or cools. Tim's commenters all appear to be dismissive experts on the topic without actually having read much about it.

On the (perhaps slim) chance that Tim or his readers will follow my advice to look at it harder before pooh-poohing the idea, I link to this article again. Then they can get back to me when they find an actual ocean scientist who has looked at the issue and come up saying "nah, it's nothing to worry about." (Seafriends website does not count, as I have explained before.)
