A few years ago there was a big study about preventing cattle farts by transplanting gut bacteria from Kangaroo. The new study says it won't work because the Roos bacteria are as gassy as the Cattles natural ones.

No intention to call foul (though I would prefer not to smell the actual emissions in this case! :lol: ).

You have to admit that kangaroo farts are at least one step more exotic than cow farts, though perhaps not for ozzies.

There may be a significant problem with the measuring stick scientists use to account for how much methane is affecting climate change, according to a recent study led by researchers at Oxford University.

The long-term effect of methane emissions might appear to be a lot greater than it really is when compared to carbon dioxide in terms of both gases’ potential to warm the climate. The Oxford researchers suggest a new way to account for methane that highlights the considerable differences in how each gas turns up the atmospheric furnace.

Methane is a powerful greenhouse gas, and the way scientists account for its climate impact is critical to the Obama administration’s efforts to regulate the energy industry’s methane emissions. It is also an important part of countries’ emissions reduction pledges under the Paris Climate Agreement.

Using so-called “carbon dioxide equivalents,” scientists commonly account for methane and carbon dioxide as if they are the same, and that has implications for how countries prioritize which climate pollutant to cut.

Should countries concentrate mainly on cutting carbon dioxide emissions, which will have the greatest long-term effect on the climate? Or, should they expend just as much effort cutting methane — a gas that affects the climate a lot more than carbon dioxide in the near future?

Considering that the "near future" means the next few decades its obvious that efforts should be made to cut methane NOW. Unfortunately, the Obama administrations' short-sighted program of shifting coal-fired electric plants to NG has had the perverse effect of increasing use of NG in the US, and increasing US methane emissions. This is making greenhouse warming worse. Yes there is a reduction in CO2 emissions because you reduce the use of coal---but by switching to NG there is an INCREASE in CH4 emissions, and methane is ca. 50 times more powerful in its Greenhouse warming effect then CO2 is.

The Obama people would've been a lot smarter to shut the coal-fired power plants and shift to solar and wind power instead of NG.

Cheers!

Estuaries like Chesapeake Bay could contribute more to global warming than once thought

We all know by now that methane is bad for the environment. It's one of those greenhouse gases that trap heat in the earth's atmosphere and contribute to our warming climate. It's regularly emitted during the production and transport of coal and oil, and sometimes even cows get the blame. However, a new study finds that estuaries like the Chesapeake Bay could be contributing significantly more methane to the atmosphere than once thought.

Estuaries and coastal systems are thought to be a relatively small source of atmospheric methane, as little as 3%. However, a new study from the University of Maryland Center for Environmental Science (UMCES) found that the methane building up in the Chesapeake Bay alone, if released, would be equal to the current estimates for all the estuaries in the world combined.

"This is just one estuary and there are many others that go anoxic in the summertime," said study author Laura Lapham of UMCES' Chesapeake Biological Laboratory. "We need to look at these eutrophic estuaries as perhaps a larger source of methane than we thought. This is a side effect of eutrophication that hasn't been investigated in the Bay."

Since dead zones in the coastal ocean and estuaries are expanding throughout the world, Lapham decided to look at the Chesapeake Bay, the largest estuary in the United States, to understand what happens to methane release in a body of water that undergoes dead zones on a regular basis.

Lapham studied the water at the bottom of the Chesapeake Bay over the course of a summer, setting up instruments perched above the mud that would track any signs of methane being released into the water. She found that in anoxic conditions, when there is no oxygen in the bottom layers of the Chesapeake Bay's waters, dissolved methane built up, probably coming from the mud, and when storms mixed up the invisible layers of the Bay's waters, the methane made it to the surface and into the atmosphere.

"Taken together, the time-series data shows that methane flux from the Bay is variable, potentially significant, and dependent upon storms," said Lapham.

... They estimated that 85% of the methane in the bottom water is oxidized in the water column in September.

While most of the built up methane was consumed by the end of the anoxic period, methane concentrations measured in surface water samples in June and September suggest that there was still a significant flux of methane to the atmosphere.
“There are three classes of people: those who see. Those who see when they are shown. Those who do not see.” ― Leonardo da Vinci

Insensible before the wave so soon released by callous fate. Affected most, they understand the least, and understanding, when it comes, invariably arrives too late.

One of the most important outcomes of the antifracking movement may have been that it attracted the attention of a couple of Cornell scientists. Living on the northern edge of the Marcellus Shale, Robert Howarth and Anthony Ingraffea got interested in the outcry. While everyone else was focused on essentially local issues—would fracking chemicals get in the water supply?—they decided to look more closely at a question that had never gotten much attention: How much methane was invisibly being leaked by these fracking operations?

Because here’s the unhappy fact about methane: Though it produces only half as much carbon as coal when you burn it, if you don’t—if it escapes into the air before it can be captured in a pipeline, or anywhere else along its route to a power plant or your stove—then it traps heat in the atmosphere much more efficiently than CO2. Howarth and Ingraffea began producing a series of papers claiming that if even a small percentage of the methane leaked—maybe as little as 3 percent—then fracked gas would do more climate damage than coal. And their preliminary data showed that leak rates could be at least that high: that somewhere between 3.6 and 7.9 percent of methane gas from shale-drilling operations actually escapes into the atmosphere.

The trouble for the fracking establishment was that new research kept backing up Howarth and Ingraffea. In January 2013, for instance, aerial overflights of fracking basins in Utah found leak rates as high as 9 percent. “We were expecting to see high methane levels, but I don’t think anybody really comprehended the true magnitude of what we would see,” said the study’s director.

That’s why last month’s Harvard study came as such a shock. It used satellite data from across the country over a span of more than a decade to demonstrate that US methane emissions had spiked 30 percent since 2002. The EPA had been insisting throughout that period that methane emissions were actually falling, but it was clearly wrong—on a massive scale. In fact, emissions “are substantially higher than we’ve understood,” EPA Administrator Gina McCarthy admitted in early March.

One obvious conclusion from the new data is that we need to move very aggressively to plug as many methane leaks as possible. But, containing the leaks is easier said than done: After all, methane is a gas, meaning that it’s hard to prevent it from escaping. Since methane is invisible and odorless (utilities inject a separate chemical to add a distinctive smell), you need special sensors to even measure leaks. Catastrophic blowouts like the recent one at Porter Ranch in California pour a lot of methane into the air, but even these accidents are small compared to the total seeping out from the millions of pipes, welds, joints, and valves across the country—especially the ones connected with fracking operations, which involve exploding rock to make large, leaky pores. A Canadian government team examined the whole process a couple of years ago and came up with despairing conclusions. Consider the cement seals around drill pipes, says Harvard’s Naomi Oreskes, who was a member of the team: “It sounds like it ought to be simple to make a cement seal, but the phrase we finally fixed on is ‘an unresolved engineering challenge.’ The technical problem is that when you pour cement into a well and it solidifies, it shrinks. You can get gaps in the cement. All wells leak.”

And if we didn’t frack, what would we do instead? Ten years ago, the realistic choice was between natural gas and coal. But that choice is no longer germane: Over the same 10 years, the price of a solar panel has dropped at least 80 percent. New inventions have come online, such as air-source heat pumps, which use the latent heat in the air to warm and cool houses, and electric storage batteries. We’ve reached the point where Denmark can generate 42 percent of its power from the wind, and where Bangladesh is planning to solarize every village in the country within the next five years. We’ve reached the point, that is, where the idea of natural gas as a “bridge fuel” to a renewable future is a marketing slogan, not a realistic claim (even if that’s precisely the phrase that Hillary Clinton used to defend fracking in a debate earlier this month).

We’ve become the planet’s salesman for natural gas—and a key player in this scheme could become the next president of the United States. When Hillary Clinton took over the State Department, she set up a special arm, the Bureau of Energy Resources, after close consultation with oil and gas executives. This bureau, with 63 employees, was soon helping sponsor conferences around the world. And much more: Diplomatic cables released by WikiLeaks show that the secretary of state was essentially acting as a broker for the shale-gas industry, twisting the arms of world leaders to make sure US firms got to frack at will.

To take just one example, an article in Mother Jones based on the WikiLeaks cables reveals what happened when fracking came to Bulgaria. In 2011, the country signed a $68 million deal with Chevron, granting the company millions of acres in shale-gas concessions. The Bulgarian public wasn’t happy: Tens of thousands were in the streets of Sofia with banners reading Stop Fracking With Our Water. But when Clinton came for a state visit in 2012, she sided with Chevron (one of whose executives had bundled large sums for her presidential campaign in 2008). In fact, the leaked cables show that the main topic of her meetings with Bulgaria’s leaders was fracking. Clinton offered to fly in the “best specialists on these new technologies to present the benefits to the Bulgarian people,” and she dispatched her Eurasian energy envoy, Richard Morningstar, to lobby hard against a fracking ban in neighboring Romania. Eventually, they won those battles—and today, the State Department provides “assistance” with fracking to dozens of countries around the world, from Cambodia to Papua New Guinea.

So if the United States has had a terrible time tracking down and fixing its methane leaks, ask yourself how it’s going to go in Bulgaria. If Canada finds that sealing leaks is an “unresolved engineering challenge,” ask yourself how Cambodia’s going to make out. If the State Department has its way, then in a few years Harvard’s satellites will be measuring gushers of methane from every direction.

Clinton continues to conflate and confuse the chemistry: Natural gas, she said in a recent position paper, has helped US carbon emissions “reach their lowest level in 20 years.” It appears that many in power would like to carry on the fracking revolution, albeit a tad more carefully.

Global warming is, in the end, not about the noisy political battles here on the planet’s surface. It actually happens in constant, silent interactions in the atmosphere, where the molecular structure of certain gases traps heat that would otherwise radiate back out to space. If you get the chemistry wrong, it doesn’t matter how many landmark climate agreements you sign or how many speeches you give. And it appears the United States may have gotten the chemistry wrong. Really wrong.

No, pstarr, there has been a pro-methane meme being foisted upon the world by a fossil-fuel industry that was looking to exploit both Fracking and potential Hydrate mining.

Any bad news about methane has been attacked, attempted to be discredited, suppressed.

Our corporate-owned government was convinced to use a politically expedient solution rather than an otherwise BAU and politically damaging one, to climate change. Convince everyone that methane is a solution not a problem, against all evidence to the contrary.

It worked for a while. Fudge the numbers a bit, manipulate the statistics, point to the left hand, to distract from the right, and wala, the fossil-fuel industry once again makes money hand-over-fist, while contributing to global warming at an even greater pace. All while making it look like they are doing something about climate change.

While before they would pump the oil and flare of the gas, they now have a market for that gas. And crippled the competing coal industry in the process.

Criminal is what this is. (Also brilliant. I would like to meet the person who came up with this.)

what a complete load of bollicks.
The fossil fuel industry has hardly been making money hand over fist from natural gas prices that have been hovering around $3/MMBTU (MCF) for the past number of years. Most of them are struggling to stay alive and count on the liquid fraction to stay above water. And if you actually did some research you would find that methane emissions from oil and gas activities make up only 1/4 of total global methane emissions and are about half or less of total emissions from agriculture (these are numbers from the EPA). Are you arguing that coal somehow has less greenhouse gas contribution than oil and gas activities?

Here is a paper that argues against that notion:

Brandt. A.R. et al, 2014. Methane leaks from North American Natural Gas systems. Science, V 343. Pp 733-735

Their comment was:

Many independent experiments suggest that a small number of “superemitters” could be responsible for a large fraction of leakage; recent regional atmospheric studies with very high emissions rates are unlikely to be representative of typical NG system leakage rates and assessments using 100-year impact indicators show system-wide leakage is unlikely to be large enough to negate climate benefits of coal-to-NG substitution.


And the list of authors includes scientists from Stanford, the NREL in Golden Co, University of Michigan at Ann Arbor, MIT, University of Colorado, University of Calgary, Harvard, Lawrence Berkeley, UC Santa Barbara. So unless you are arguing that somehow all the universities are wrapped up with the US gov’t in this conspiracy scheme you have cooked up I suggest you give your head a shake. :roll:

r's arguments here are so idiotic, it's really hard to know where to begin.

The first one is basically the same as saying: My lottery pick didn't win, so I obviously didn't buy my ticket with the intention of making any money.

The second is essentially: Some methane leaks pollute more than others, so methane pollution isn't a problem.

Really, way too idiotic on the face of them to even start. But a tacit admission that he is without any actually valid arguments, so again, a tacit agreement with cid's post.

Once again showing either your inability to read posts or actually understand anything.

It was claimed:
fudge the numbers a bit, manipulate the statistics, point to the left hand, to distract from the right, and wala, the fossil-fuel industry once again makes money hand-over-fist, w

to which I responded that oil companies have hardly made money hand over fist given they are struggling at natural gas prices over the past few years to turn a profit at all.
It was also claimed: the gas production has crippled the competing coal industry (this being presented as if it was a bad thing).
The paper I pointed to indicated that regardless of there being more methane released from well
asassessments using 100-year impact indicators show system-wide leakage is unlikely to be large enough to negate climate benefits of coal-to-NG substitution.


As well pointing fingers at the oil and gas industry with regards to methane when the total industry only accounts for 1/4 of the emissions is at best ridiculous. Add to that the EPA Greenhouse Gas Reporting Program in 2015 indicated that since 2011 methane emissions from the Petroleum and Natural Gas sector have decreased steadily form 83.6 MM Tonnes to 73.0 million Tonnes during a period where shale gas exploration was rapidly expanding.

In summary:

- oil and gas companies are not making windfall profits from natural gas, they haven't since around 2007
- CH4 emissions from oil and gas operations have been decreasing while activity has been increasing
- CH4 emissions from oil and gas operations are only 1/4 of the total known emissions. Agriculture makes up a much larger percentage.
-CH4 super emitters (single wells with a casing leak much like in California recently) account for the largest proportion of methane release from oil and gas.....fixing a few wells could almost eliminate the problem. The suggestion that all wells leak methane is absolutely absurd.

So perhaps before you call someone an idiot you should do a bit of research and actually look in a mirror.
