Are flatulent shellfish really contributing to climate change?

Scientists investigating marine life in the Baltic Sea have found mussels, oysters and clams are emitting greenhouse gases - but cows still trump themSwedish scientists have found that flatulent shellfish are creating vast amounts of greenhouse gases, leading to a predictable slew of comments about farting cockles and clams. But beneath the schoolboy humour, there is a serious point. The two gases in question - methane and nitrous oxide - are potent agents of climate change, with a warming potential 28 and 265 times greater than carbon dioxide respectively.Scientists studying the Baltic Sea off the coast of Sweden have found that shellfish are producing one-tenth of all the greenhouses gases released there - the equivalent to the amount produced by 20,000 cattle. If the same situation is being replicated around the rest of the world's seas and oceans, we have a serious problem. Continue reading...
