Pteropod risk

I've been mentioning pteropods here in the context of ocean acidification for many years.

Here's a good Scientific American blog post summarising the current state of play, and discussing the consequences of their loss or reduction. Worth reading.

Note the reaction of the first commenter: he won't subscribe to Scientific American again because it is being unscientific. (It is, in fact, a very balanced article.) There's nothing like putting your fingers in your ears and saying "I can't hear you". (I'm sure he'll take them out to listen to Judith Curry, though.)
