Sometimes the press office puts out a good release,
Natural gas is mostly methane, which is a much more potent greenhouse gas, especially in the short term, with 105 times more warming impact, pound for pound, than carbon dioxide (CO2), Howarth said, adding that even small leaks make a big difference. He estimated that as much as 8 percent of the methane in shale gas leaks into the air during the lifetime of a hydraulic shale gas well -- up to twice what escapes from conventional gas production. . . .and then the churnalists get to it. On the other side of the sausage grinder here is a lovely example of the perversity argument from Eve Troeh on Marketplace (NPR)
He noted that the hydraulic fracturing process lends itself to more leakage because it takes more time to drill the well, requires more venting and produces more flowback waste, he said.
"A lot of the data we used are really low quality, but I'm confident they are the best available," Howarth said. "We want to go out into the Marcellus Shale and do micrometeorological fluxes of methane at the time of venting and get a real number on this, which has never been done. We're optimistic we can get funding and do that over the next year."
"We've tried to be conservative all along; we're not trying to be hyperbolic in our statements," Ingraffea said.
"We do not intend for you to accept what we've reported on today as the definitive scientific study in regards to this question. It's clearly not," he added. "What we're hoping to do with this study is to stimulate the science that should have been done before. In my opinion, corporate business plans superseded national energy strategy."

Robert Howarth: But that of course is only part of the greenhouse gas footprint.
Cornell University professor Robert Howarth. His new study is the first to quantify the whole carbon footprint for natural gas. He found it's more Bigfoot than Bambi. Because when you crack shale to get to the clean-burning fuel, out comes "methane" -- another greenhouse gas. He says that's worse than burning coal.
Maybe, but that natural gas bridge might not be as sturdy as previously thought, according to a Cornell University study in the upcoming May issue of Climatic Change Letters. Cornell ecologist Robert Howarth, a lead author of the study, says in a university release that methane ( a potent global warming gas) leakage from a controversial drilling method (known as fracking) offsets the lesser carbon emissions that makes makes natural gas more attractive in comparison other fossil fuels:You know, who would have guessed that natural gas is mostly methane. Eli told the bunnies that you just have to taste the blather to spot the rejectionists. Time for the Coven to call another blogger ethics panel.
Oh yeah, in case anyone cares, leakage from natural gas pipelines contributes strongly to methane emissions and atmospheric methane is degraded to CO2 in ~10 years. Let us not talk about the cows. This is a family blog.
