How Big a Contributor is Global Warming Methane to the overall issue?
According to the International Panel of Climate Change (IPCC) the effect on Global Warming of human generated greenhouse gases breaks down as follows: • CO2 69.9% • CH4 22.9% • N2O 7.1%So you can see methane or CH4, is a significant player. The fact that is a short lived gas makes it an especially good candidate having a relatively quick effect. Where does Methane come from? Methane comes both from human activity and from natural sources. About 30% of Methane comes from natural sources – and most of that is from wetlands. The balance of 70% of methane production comes from human activities. The breakdown worldwide on methane contributions is shown here in this pie chart. The biggest three contributors worldwide are: • Enteric Fermentation • Oil, Gas and Coal Mining • Rice ProductionEnteric fermentation is science’s way of describing a digestive process that results in serious gas. Cows are the biggest contributors and both ends have a crack at it – so it’s the burps and farts of the gr
