A study was published in Journal Science that claims the U.S. EPA under-counted total methane emissions by roughly 50%.
Based on atmospheric sampling, the study estimates that this missing methane amounts to 14 terra grams (Tg) of methane; that's equal to 6.4 billion
pounds, or as much as the weight of 1.4 million new Ford F150 pickup trucks.
If people continue to deny what's happening folks, we're going to pass the tipping point real soon and then there won't be any damn thing we can do
about saving our arses. We'll be entering a human extinction level event. Through my dangerous gas theory threads I list a series of different
phenomenon that I believe are caused by rapidly escalating amounts of methane gas in the atmosphere, trapping the sun's heat at dangerous levels,
causing global temperatures to rapidly rise. Some of those events include the sonic booms, sky noises, volcanoes, earthquakes, sinkholes, torrential
rains, high winds, freak hail storms, mysterious explosions and fires, unexplained human deaths, mass animal die-offs, disease outbreaks, and more.
You can check all this out in my threads.
Methane is 20 times worse than carbon dioxide as far as trapping the sun's heat but it has a much shorter life span at just under a decade. So,
normally, it wouldn't be such a threat because of its short life span but when there's too much releasing, then it's far worse, which is what's
happening today. It's more of a threat to global warming because excess hydrogen sulfide release right along with methane is causing more methane to
emit because the hydrogen sulfide is reacting away the hydroxyl radicals that always mitigated the amount of methane. It's a chain reaction that is
getting out of control, because the more gases that release, the more the temperatures continue to climb, causing more gas to release. The hydroxl
radicals can't keep up. We're definitely fast approaching a tipping point.
One area that should be of great concern is the Arctic region. This area is warming on average the fastest out of anywhere on the planet and it has
the most vulnerable of methane storage with frozen hydrates of the gas by the billions of tons in the shallow Arctic shelf. This gas is stored just
under the permafrost. Normally, hydrates in the deeper ocean are so far below that it takes a lot longer to warm those waters and much longer after
that for the hydrates to melt, but in the shallower waters of the shelf, it's already happening.
According to this article, they believe 17 million tons of methane gas per year is escaping from the East Siberian Arctic Shelf alone.
Twice as much methane releasing from Arctic Shelf than previously
In an effort to hide the dangers of Fracking, the government via the EPA just recently released a report that methane emissions from natural gas are
actually decreasing. The EPA claimed that 2012 data showed a 2% decrease in emissions from 2011.
ethane pollution from US far worse than anyone realized
This treatment of methane emissions from natural gas is difficult to reconcile with the new Science study by Adam Brandt of Stanford University and
his colleagues, the most comprehensive analysis of both "top-down" and "bottom-up" methane-emission studies ever.
Top down studies take air samples from aircraft or towers. These types of studies offer an accurate measurement of overall methane emissions, but they
are not as well suited to attributing emissions to particular sources compared to bottom-up methods, which measure emissions directly at the source.
The estimates of missing methane are based on direct sampling of the atmosphere, whereas the EPA inventory involves many assumptions and depends upon
accurate self-reporting of voluntary emission reduction efforts by the extraction companies.
GRAPH: The bar on the left shows the total methane emissions, including three largest sources, for the year 2012 in the U.S. Environmental Protection
Agency (EPA) Greenhouse Gas Inventory (draft version released February 2014). The next bar shows the most likely estimate of missing methane (50
percent under counting) on top of the emissions in the EPA inventory. The two bars to the right represent the lower and upper ends of the possible
ranges for missing methane, 25 percent and 75 percent as large as the EPA inventory total.
The EPA greenhouse gas inventory uses data from "bottom up" studies to develop emission factors for different components of the entire natural gas
system from production (extraction from the ground), to processing, transmission and distribution. These emission factors are part of an attempt to
calculate representative quantities of pollution released with each of the activities that make up the natural gas system. Roughly speaking, there is
an emission factor for conventional-well completions and a lower one for reduced-emission-well completions that use pollution controls. The emission
factor is multiplied by the number of well completions of each type to estimate their contribution to total emissions from the natural gas system.
A limitation of the bottom-up studies upon which the EPA inventory relies is a requirement that researchers obtain access to natural-gas operations.
It has been challenging for researchers to secure permission to do that type of work. As a result, bottom up studies struggle to attain large sample
sizes that would give confidence that they are broadly representative of the whole industry. There is also a concern that the companies that volunteer
to be measured are likely to be the most responsible operators, i.e. lower emitting. Evidence is accumulating that a small number of leaks are
responsible for a large fraction of methane emissions, and these outlier emissions are most likely emanating from the less-responsible producers.
The evidence is all around us every single day, but the government, the media and the powers that be are trying to hide it from us. All these
phenomenon should be garnering much more news attention than it does, but it's largely ignored. These phenomenon are rising in intensity and
frequency. Freak storms, extreme heatwaves, massive sinkholes, fireballs, more and more disease and drug-resistant bacteria, earthquake swarms,
volcanic activity, massive gas explosions and sonic booms...it's all there every single day. All you have to do is pay attention and you'll see for
yourself. These things aren't normal at this frequency of occurrence. Sure, they are things we've experienced before, but not like this. We all need
to collectively come together and change our attitudes before it's too late!
