Terra Daily: Unlike carbon dioxide and methane, laughing gas has been largely ignored by world leaders as a worrying greenhouse gas. But nitrous oxide must be taken more seriously, says Professor David Richardson from the University of East Anglia in Norwich, UK, speaking today (Monday 31 March 2008) at the Society for General Microbiology's 162nd meeting being held this week at the Edinburgh International Conference Centre."It only makes up 9% of total greenhouse gas emissions, but it's got 300 times more global warming potential than carbon dioxide", says Prof Richardson. "It can survive in the atmosphere for 150 years, and it's recognised in the Kyoto protocol as one of the key gases we need to limit".
The potent gas is mainly coming from waste treatment plants and agriculture. Its release is increasing at the rate of 50 parts per billion or 0.25% every year. This means that it can be better controlled with suitable management strategies, but only if the importance of nitrous oxide (N2O) is widely recognised first....
