The more carbon dioxide in the air, the more acidic oceans become – preventing oysters and tiny marine snails at the base of the food chain from forming shells.

OSU Study Explains How Even A Little Ocean Acidification Can Kill Baby Oysters

Ecotrope | June 12, 2013 11:51 a.m.

A new study by Oregon State University researchers found that acidic water adds stress during a time when baby oysters are already in a "death race" to build their first shell. Researchers concluded that water with elevated carbon dioxide levels can cause the oysters to lose that race – even if the water isn't fully corrosive.

Do oceans need their own climate policy?

Lots happening on the climate front already this week. I read with interest about an investigation of the International Panel on Climate Change. Apparently, according to the independent auditor InterAcademy Council, even Nobel Peace Prize winners aren't perfect.
