Huge Methane Spike may be Tied to Fracking

Methane gas flares in North Dakota oil fields – visible from space.

Climate Central:

There was a huge global spike in one of the most potent greenhouse gases driving climate change over the last decade, and the U.S. may be the biggest culprit, according a new Harvard University study.

The United States alone could be responsible for between 30 percent and 60 percent of the global growth in human-caused atmospheric methane emissions since 2002 because of a 30 percent spike in methane emissions across the country, the study says.

The research shows that emissions increased the most in the middle of the country, but the authors said there is too little data to identify specific sources. However, the increase occurred at the same time as America’s shale oil and gas boom, which has been associated with large amounts of methane leaking from oil and gas wells and pipelines nationwide.

“I’d say the biggest takeaway is that there is more we — the U.S. — could be doing to reduce our methane emissions to combat climate change,” study lead author Alex Turner, a Harvard University chemical engineering Ph.D. candidate, said.

The Aliso Canyon gas leak in California, which was plugged last week after a nearly four-month effort to contain it, has brought new attention to methane. The gas is roughly 86 times as potent as carbon dioxide as a driver of climate change over a period of 20 years, or 35 times as potent over the span of a century. The Aliso leak spewed enough methane into the atmosphere to equal the greenhouse gases emitted by more than 440,000 cars in a year.

The U.S. Environmental Protection Agency is trying to rein in methane emissions from oil and gas operations, and has proposed new rules to curb them from oil and gas wells. The Obama administration’s Climate Action Plan seeks to cut methane emissions from the oil and gas industry by up to 45 percent below 2012 levels by 2025.

Global methane emissions have risen and fallen several times since the 1980s, Turner said, but they’ve been rising continuously since 2007.

“The causes for this renewed growth are currently unknown,” he said,

In the U.S., the official government tally of the country’s annual human-caused methane emissions between 2002 and 2012 shows that emissions have been about 29 million metric tons annually, without any significant trends up or down. Research by Turner’s team, however, showed that emissions ranged from about 39 million tons to about 52 million tons during that period. The team based its findings on satellite data.

The Harvard study, published last week in the journal Geophysical Research Letters, adds to mounting research that shows that the government’s official tally of methane emissions is not consistent with observations made by universities and other institutions.

The official tally, taking what ‘s known as a “bottom-up” approach, calculates methane emissions based on expected leak rates at oil and gas well sites, not actual measurements. The Harvard researchers used a “top-down” method, calculating emissions based on actual satellite measurements, showing that U.S. methane emissions are far greater than those estimated by the government.

    I consider the difference between two headlines:

    “Huge Methane Spike may be Tied to Fracking”

    and

    “Huge Methane Spike is Tied to Fracking”

    … and I wonder how many folk actually think:

    “Ain’t plausible deniability great?”

    Ho-hum. Another methane spike? And gas flaring in North Dakota visible from space? We haven’t done much about the methane spike discovered a few years back in the Four Corners area. Or the methane that seems to be erupting wherever gas or oil wells are drilled, processing plants are built, or pipelines are run to transport the fossil fuels Let’s just keep pumping it out until we hit a tipping point and set off the methane bomb, then we’ll have lots of it and can REALLY see if it’s as bad as the scientists say.

    “The causes for this renewed growth are currently unknown”. Really?

    “….mounting research that shows that the government’s official tally of methane emissions is not consistent with observations made by universities and other institutions”. Is someone lying to us? Is Donald Trump going to fix this too?

    Scientists have been saying that we don’t have enough data-taking instrumentation in the places needed to understand methane emissions and prospects, and I don’t doubt the truth of that. It’s one thing to say the source is “unknown” (I accept we’re not sure) and quite another if someone were to say “unexpected and not what we figured would happen” (which would be, well DUMB)

    “And for the Winter of 2016 it’s possible that the Arctic may never experience typical conditions. For, according to NOAA, the first half of February saw this record, Spring-like, warmth extend on through today. It’s as if these coldest zones in the Northern Hemisphere haven’t yet experienced Winter — as if the freak storm that drove Arctic temperatures to record levels during late December has, ever since, jammed the thermometer into typical April levels and left it stuck there. ” Robert Scribbler

  5. ” The gas is roughly 86 times as potent as carbon dioxide as a driver of climate change over a period of 20 years, or 35 times as potent over the span of a century.”

    If I may

    However the short term GHG effect (<10yr) is closer to 100 x CO2.
    The point is that increasing Global Methane level is all at this instant at max GHG potential, those lower figures reflect it's decrease over time, assuming it will decrease substantially axs more of the World takes the fracking and gas path and the permafrost and clathrates melt
