Mr. Brendan Gleeson:

Good, yes, write it down. On the methane argument, methane is a flow gas; it flows into the atmosphere and ten or 11 years later it flows out. That is a double-edged argument for agriculture. I believe it has been articulated in a particular way by stakeholders but it is a double-edged argument. I believe it means that if one increases the volume of methane in the atmosphere, it has a much more dramatic warming effect than CO2. In the short term it has a much more dramatic warming effect but if we want to stop methane contributing to global warming, it must be stabilised and reduced slightly. Then the overall volume of methane in the atmosphere is not increasing and the warming effect of methane will have been stabilised.
