The Methane Thread pt. 2

I just heard on the NPR news that CO2 emissions didn't increase last year, according to BP.

BP credited this to the fact that the US is switching from coal to NG, and BP promised to provide everyone with as much NG as they want.

Of course, what BP left out is that NG drilling, transport and storage all result in METHANE emissions, and use of more NG means more CH4 emissions. Sure enough, emissions of CH4 are now surging and adding more and more to global Greenhouse Warming. AND, Of course, the Paris Accords, conveniently enough for BP, don't even mention methane.

"Global concentrations of methane, a powerful greenhouse gas and cause of climate change, are now growing faster in the atmosphere than at any other time in the past two decades.
That is the message of a team of international scientists in an editorial to be published 12 December in the journal Environmental Research Letters. The group reports that methane concentrations in the air began to surge around 2007 and grew precipitously in 2014 and 2015. In that two-year period, concentrations shot up by 10 or more parts per billion annually. It's a stark contrast from the early 2000s when methane concentrations crept up by just 0.5 parts per billion on average each year. The reason for the spike is unclear but may come from emissions from agricultural sources and mainly around the tropics - potentially from farm sites like rice paddies and cattle pastures.

----------------------------------------

It seems unlikely to me that the surge in CH4 in the atmosphere reflects rapid changes in rice patties as the authors of this report seem to believe. It seems far more likely the it reflects new releases of CH4 accompanying fracking and production of NG, something that grew rapidly at the same time as the surge occurred.

Plant - "It seems far more likely the it reflects new releases of CH4 accompanying fracking and production of NG, something that grew rapidly at the same time as the surge occurred.". The only problem with that theory is that any methane leaks would be coming from the well head or along the pipeline transmission or local distribution systems. But at all those junctures the nature of the completion (frac'd hz shale reservoir or vertical convention sandstone reservoir) is "invisible". IOW the equipment and process is identical for both scenarios. And let's not forget recent survey found a shockingly high number of leaks from local distribution systems. And as the article points out we're distributing and burning more NG year after year.

Not a strong (or provable) opinion but I wonder about two potential increased contributors. One, increased production from foreign NG/condensate fields where regs against venting (as opposed to flaring) either don't exist or are weakly enforced. Second increased production, transport and regassification of LNG.

New technologies like IR imaging can see the NG leaks at some drilling and production sites quite clearly.

Other new technologies can "sniff" out NG leaks. Taken together, new studies show that methane leaks from oil and gas are much greater then previously thought.

Yup. I agree 100%. There appears to be small amounts of leakage of methane at many points throughout just about all NG delivery and storage networks.

ESRL does not post CH4 level updates with anywhere near the frequency that they post CO2 updates, it is more nearly a quarterly update than a daily update. That being said this graph is also worth keeping an eye on like the ones I posted earlier.

Image

ESRL NOAA wrote: The annual increase in atmospheric CH4 in a given year is the increase in its abundance (mole fraction) from January 1 in that year to January 1 of the next year, after the seasonal cycle has been removed (as shown by the black lines in the figure above). It represents the sum of all CH4 added to, and removed from, the atmosphere during the year by human activities and natural processes. Our first preliminary estimate for the annual increase of a particular year is produced during April of the following year, using available data from the previous year. It is important to recognize that the initial, April estimate of the annual increase is likely to change significantly as more data are added to the analysis. That estimate will be updated in subsequent months as more samples are measured for CH4 and included in the analysis. By autumn of the following year the annual increase will typically converge toward a “final” value.

Estimates of the globally-averaged CH4 abundance (monthly- and annually-averaged means), and the annual increase, are updated every month as new samples are returned to Boulder, measured for CH4, and added to the analysis. Adding new, more recent data improves the accuracy of the initial estimate by increasing the spatial density of data and eliminating “end effects” of the curve fitting procedures used. We’ve investigated the impacts of adding new data to the parameters reported here, and a summary of the results follows:

Initial estimates of the CH4 annual increase made in April for the previous year are biased compared to those that follow using additional data. The average bias in the initial estimate is +1±0.8 ppb yr-1 (1 standard deviation shown). Over the next few months, the average bias slowly decreases until it is negligible by July or August. In any given year though, bias in the initial estimate of the annual increase can be much larger than the average, with bias up to ±3 ppb yr-1; that is, it can be positive or negative. In other words, until late in a year, bias in the annual increase can be much larger than the uncertainty reported based on the bootstrap method described below.

Behavior of initial annually-averaged means and monthly-averaged means are similar (see links to files below). For monthly mean CH4, the initial value is typically too high, by up to 7.6 ppb.

The estimated uncertainty in the global annual CH4 increase varies by year, and it has been estimated by a “bootstrap” technique for 1984 and later. One hundred different realizations of a global network were constructed by randomly picking sites, with restitution, from the existing marine boundary layer sites in the NOAA/ESRL cooperative global air sampling network (Dlugokencky et al., 1994). Each member of the ensemble of networks has the same number of sites as the real network, but some sites are missing, while others are represented more than once. An additional condition is that at least one site is present from high southern latitudes, one from the tropics, and one from high northern latitudes, because we have always maintained broad latitude coverage in the real network. Temporal data gaps at individual sites are present in the bootstrap networks. We calculate the mean for each year's annual increase from the ensemble members, and we use one standard deviation as an estimate of the uncertainty. Uncertainties for monthly and annual means are also estimated. As mentioned earlier, bias in our first estimates of annual increase, monthly mean and annual mean can be significantly greater than the stated uncertainty.

Nice graph. It looks to me like a pattern of steady linear increase up to about 2000, then something of a ten-year plateau, and now a return to that steady linear increase.

Is there anything else in the data or text you see as something we should especially note or watch out for?

And do you or anyone have links to articles on isotope features of the atmospheric methane that might give some clue as to how much of the new increase has to do with fracking and leaks of NG, and how much to other sources (extensions of rice ag in the tropics...)?

Google pulled this up but I don't have access to the full article.

Abstract
Between 1999 and 2006, a plateau interrupted the otherwise continuous increase of atmospheric methane concentration [CH4] since preindustrial times. Causes could be sink variability or a temporary reduction in industrial or climate-sensitive sources. We reconstructed the global history of [CH4] and its stable carbon isotopes from ice cores, archived air, and a global network of monitoring stations. A box-model analysis suggests that diminishing thermogenic emissions, probably from the fossil-fuel industry, and/or variations in the hydroxyl CH4 sink caused the [CH4] plateau. Thermogenic emissions did not resume to cause the renewed [CH4] rise after 2006, which contradicts emission inventories. Post-2006 source increases are predominantly biogenic, outside the Arctic, and arguably more consistent with agriculture than wetlands. If so, mitigating CH4 emissions must be balanced with the need for food production.

dohboi - "...clue as to how much of the new increase has to do with fracking and leaks of NG..." As explained above if the increase of atmospheric methane is due to leaking wells and/or transportation and local distribution systems it still wouldn't be related to frac'ng. Any leaks are happening "downstream" from the completion be it a frac'd or conventional completion. If the numbers are correct I would suspect two potential sources first. One, from the expanding local distribution system which have been documented to have a much higher leakage then many had assumed. Particularly since NG has been replacing coal in power generation. Second would be increased venting from fields that are primarily producing condensate and flaring (which has been proven to not be 100% effective) and intentional venting.

IOW there are many opportunities for methane leaks throughput the entire dynamic. And also potential for leakage not related to production activity, such as permafrost melting.

MBS - Not familiar with his work. But the chemistry is rather simple. NG is a fossil fuel that produces GHG when burned. Consume more NG and produce more GHG.

But of course it's not just an issue of 'when it's burned.'

When it escapes unburned into the atmosphere it is dozens of times more powerful as a greenhouse gas than the CO2 it would become if burned, right?

dohboi - If we didn't increase the burning of NG we wouldn't be trying to produce more NG. And if we didn't produce more we wouldn't have more potential NG leaks.

Same difference except we are producing much more CO2 by burning NG even if you take into account the greater negative effect of methane.

Contraposition found?!

Enhanced CO2 uptake at a shallow Arctic Ocean seep field overwhelms the positive warming potential of emitted methane


Methane released from the seafloor and transported to the atmosphere has the potential to amplify global warming. At an arctic site characterized by high methane flux from the seafloor, we measured methane and carbon dioxide (CO2) exchange across the sea−air interface. We found that CO2 uptake in an area of elevated methane efflux was enhanced relative to surrounding waters, such that the negative radiative forcing effect (cooling) resulting from CO2 uptake overwhelmed the positive radiative forcing effect (warming) supported by methane output. Our work suggests physical mechanisms (e.g., upwelling) that transport methane to the surface may also transport nutrient-enriched water that supports enhanced primary production and CO2 drawdown. These areas of methane seepage may be net greenhouse gas sinks.

http://www.pnas.org/content/114/21/5355
**********************
ONE Study found
Methan can direct or indirect feed algae which sucks CO2 out of the atmosphere

Be careful reader a massiv methan blow out means not less CO2 but armageddon.

So the CH4 doomsday triggered by global warming is still possible and is not canceled here :idea: :!:

Vast amounts of methane exists within ocean floor sediments on the Eastern Siberian Arctic Shelf, in the form of methane hydrates & free methane gas. Up to recently, gas release to the shallow water column (50 meters deep) & atmosphere has been slow, with the subsea permafrost acting as a million corks on a million champagne bottles to contain the methane. Now, rapid thawing of the permafrost has released 10% of the corks, allowing rapid ongoing increases in methane release.

See the ground bubble up!

Methane is between 100 and 120 times more potent as a greenhouse gas than carbon dioxide. This being said there is enough methane trapped under the permafrost in the arctic to extinguish all life on earth many times over. This is not a good situation to have on an ever warming planet where the poles are the most susceptible to changes in the environment. Russian scientists have recently discovered more than 200 lakes that are bubbling and releasing methane. Also very large holes and craters that used to have an unknown origin have also been attributed to the methane gas being released. This is a very urgent and dire situation that all of humanity needs to focus on right now or else there wont be a foreseeable future for anyone.


This event, methane up and sea ice gone might be the most important event ever happening on Earth, the fastest most lethal extinction event ever.
The dino's were wiped out by an astroid but the other extinction events were Climate related events, abrupt and likely caused by the methane mechanism.
Unfortunately we will all soon find out how rapid and how lethal it is.
