Warmer oceans release CO2 faster than thought - environment - 25 April 2011. As the world's oceans warm, their massive stores of dissolved carbon dioxide may be quick to bubble back out into the atmosphere and amplify the greenhouse effect, according to a new study.
The oceans capture around 30 per cent of human carbon dioxide emissions and hide it in their depths. This slows the march of global warming somewhat. But climate records from the end of the last ice age show that as temperatures climb, the trend reverses and the oceans emit CO2, which exacerbates warming. Previous studies have suggested that it takes between 400 and 1300 years for this to happen.

It is easy to believe that there is little we humans can do to harm, or for that matter protect, the colossal oceans. Our perception of human impotence, of our inability to affect the oceans, is deeply rooted in the way we govern the seas today. Cmsdata.iucn.org/downloads/ipso_workshop_report_june_2011.pdf.
