It has been scientifically proven that Old Farts emit 200% more methane and hydrogen sulphide (that's the smelly stuff), than a regular lentil eating Greenie or the average old moo'. It has been established that the Old Farts exclusive diet of "Baked Beans in Tomato Sauce" is the cause of their excessive flatulence. Fortunately, a breakthrough remedy has been discovered, its the "Corker", once inserted in the appropriate orifice, the "Corker" will permanently prevent the expulsion of these nasty climate destroying gases!

As the village idiot is one of the oldest farts on OLO I guess that he is talking about himself.

What the moron forgets is that leafy vegetables eaten by gangreens also create lots of gas and measures taken by paedophile greenie Jono Doig don't help reduce gas.

No need for profanities Hasbeen! Nothing I said was incorrect.
The CO2, which I didn't mention, is largely a red herring for obvious reasons that you and Shadow acknowledge. Although there are exceptions, such as when deforestation is involved. Farming can be sustainable; that doesn't mean it always is.

But methane has a much higher global warming potential despite its short atmospheric half life. An overview can be found at http://www.epa.gov/ghgemissions/understanding-global-warming-potentials

There are different calculations done over different timeframes, so you could argue the appropriateness of the timeframe. And there is uncertainty of the atmospheric half life of methane: a twelve year figure is most commonly used. But even if we go with Shadow's optimistic eight years, the 60 year results are VERY far from "vanishingly close to zero".

Did you miss the point accidentally, intentionally, or do you simply not understand Aidan?

Cows can only produce in farts & burps, what they have taken in in the grass & other carbohydrate. If they don't do so either other, mostly termites or rot will produce the same chemicals into the atmosphere, even quicker. At least cows will have a period where they will sequester some of the CO2 used by the grass to grow.

What is it you don't understand about this?

Shonky Trumpster,

Since you mentioned it yet again. You seem to have a fetish with paedophilia and paedophiles, you mention them often enough here, you must get off on it or something?

Hasbeen,
No, I didn't miss the point. I saw that the point you were trying to make was based on false assumptions and red herrings.

You have greatly underestimated the global warming potential of methane. You seem to regard it as similar to CO2, but in reality it's a lot higher,. The IPCC has rated it at 56 times higher over 20 years, or 21 times higher over 100 years. If new high quality research shows the methane's atmospheric half life to be lower, that's good news - but there's no way it would make the figure "vanishingly small".

Cows v termites is another red herring. Yes, cows do compare favourably in that regard, but it's unlikely the grass would be consumed by termites if the cows weren't there. Grazing by kangaroos would be a more sensible comparison, and there the cows compare very unfavourably (though as I said before, dietary supplements can change that).
