Katey Walter, a researcher at the University of Alaska at Fairbanks, has spent the past few years mapping and measuring hot spots of methane emission in the rapidly melting regions of Alaska and Siberia.
On the long term (longer than a few decades) the transient methane concentration is determined by the chronic rate of methane emission to the atmosphere.
But the new Purdue study suggests the EPA's inventories may not be quantifying all the methane emissions from wells being drilled because few people have measured methane leaking from wells in the earliest stage of well development — the actual drilling itself.
On the long term (longer than a few decades) the transient methane concentration is determined by the chronic rate of methane emission to the atmosphere.
When you add up that there is more methane being emitted than E.P.A. has estimated, that methane is responsible for up to half of all the greenhouse gas emissions for the entire US, and that each unit of methane emitted is far more important in causing global climate change over the critical few decades ahead, it should be clear that bridge - fuel argument just doesn't hold up.
You keep ignoring the fact that there is no evidence for methane burps associated with conditions in the relatively recent past (early Holocene, Eemian) for which there is good evidence for warmer Arctic conditions than now, and you are happy to extrapolate emissions of a few Tg (at most) to values 1000 times larger on the basis of nothing very much.
More importantly, the atmospheric methane flux from the Arctic Ocean is really small (extrapolating estimates from Kort et al 2012), even compared with emissions from the Arctic land surface, which is itself only a few percent of global emissions (dominated by human sources and tropical wetlands).
With fewer solids there is a decrease in anaerobic decomposition and a reduction in the production of methane emissions.
«Recent studies show methane emissions are a fraction of estimates from just a few years ago.»
Reductions in some short - lived human - induced emissions that contribute to warming, such as black carbon (soot) and methane, could reduce some of the projected warming over the next couple of decades, because, unlike carbon dioxide, these gases and particles have relatively short atmospheric lifetimes.The amount of warming projected beyond the next few decades is directly linked to the cumulative global emissions of heat - trapping gases and particles.
the atmospheric methane flux from the Arctic Ocean is really small (extrapolating estimates from Kort et al 2012), even compared with emissions from the Arctic land surface, which is itself only a few percent of global emissions (dominated by human sources and tropical wetlands).
For years, scientists weren't sure what was behind the rising levels of methane, but they had a few ideas: namely an increase in fossil fuel - related emissions.
«The industry has led efforts to reduce emissions of methane by developing new technologies and equipment, and recent studies show emissions are far lower than EPA projected just a few years ago,» said Howard Feldman, head of scientific and regulatory affairs at the American Petroleum Institute.
Though he warned that carbon dioxide emissions must be stabilized over the next few decades, he also suggested that significant progress could be made by reducing the emissions of other greenhouse gases, particularly methane and ozone — and that we must pay our Faustian debt involving air pollution.
