back to article Cow flatulence, gas emissions much worse than thought - boffins

A new study has revealed that the amount of methane – a greenhouse gas 20 times more potent but far less prevalent than CO2 – released into the US atmosphere is significantly higher than previously thought. "We find greenhouse gas emissions from agriculture and fossil fuel extraction and processing (i.e., oil and/or natural …

    Carbon dioxide, 0.04% of the earth's atmosphere.

    Methane, 0.00017%.

    There is no way that these two "greenhouse gases" would be able to warm the earth.

    Yes, the climate is changing, but it has nothing to do with those two gases

        You are using brilliant logic there yourself. Comparing 0.04% of the entire earths atmosphere with CO2 to 0.04% of a human body with a deadly toxin. With that kind of logic, I can see why you would buy into Man Made Climate Change.

        Higher CO2 means more rays are reflected back, but only up to a certain level where it reaches maximum. Same for ozone, which does not take a lot to reflect harmful rays.

    3. Grant Alexander

      More importantly, even though CO2 concentration has increased the temperatures have been stagnant for the last 17 years (according to the IPCC). So how big an effect does CO2 have on the earth's climate????

    4. etoile

      CO2 has the structure o, O-C-O which make it very good at rëemitting certain infrared (IR) frequencies. Methane (CH4) has a different structure that makes it very good at sending IR heat back to Earth at frequencies different then CO2. It is because no other atmospheric gasses, except some CFC's, transmit in those frequencies that make CH4 such a strong "greenhouse gas." Picture it this way, take a piece of glass 2 cm thick that is invisible to IR and then coat one side with a fume of shiny gold a few atoms thick —they do such for high-rise buildings—. and see how 98% of the IR is reflected. The gold on the glass would be only a few 10 millionths of the glass, but the glass does not react to that wavelength and gold does. Because of that CH4 is much, much stronger then CO2 and CO2 is much much stronger then the IR transparent nitrogen. Side note, the sky is blue because nitrogen is effected by high frequencies.; if it were mostly CO2 it would be brownish-red. I could show how the basic physics work in less then six hours, which is too long for here. Please read up on it, It really quite interesting. Uni of Chicago has some free online lecture on this.

    I find it hard to believe that the amount of cow methane can be measured with any accuracy. It sounds like little more than an alarmist theory. I suppose someone will ask farmers to add pilot lights to both ends of the poor cow to burn off the offending methane. Then someone else will decide that cows blowing fire are dangerous and make the farmers paint them with warnings to the public to stay back 50 feet. Of course these cows will be blamed for countless prairie and barn fires and there's the smoke problem and the ASPCA will certainly gripe about the occasional exploding cow. It will turn into such a complicated mess. So, I think maybe I'll just tolerate the cows farting and belching for now.

    1. Grant Alexander

      My idea is the genetically engineer the cow out of the process. We just have to splice the gene for converting grass to milk into the grass and fire the cows. Graminacae mammalari would undertake the whole process in one organism.

        IIRC there is a fairly simple supplement to the diet that will cut Methane release in cows. I think its part of why some pasture is bad for cow farts and some is not.

    3. cray74

      @snerdguy: Really, it's hard to believe that the methane emissions can be measured accurately? There's some ways that jump to my mind:

      1) Determine mass of fodder converted to fumes (water vapor, carbon dioxide, methane), an easy enough process: monitor mass of fodder fed to an experimental group of cows; monitor the mass of the cows; monitor the mass of the solids and liquids coming out. The difference is lost as gas. Then rig a gas sampling system near the cow's mouth and ass and compare cow fumes to ambient air. Apply the resulting percentages to the mass of cow gas. You'll get your methane estimate from it. This technique is easiest when you have plentiful biology interns and shovels available.

      2) Bigger budget biologists can take a more controlled environment approach: shove a cow and fodder into a sealed, climate-controlled room and rigorously track important masses and atmospheric composition. If you know the atmospheric mass and composition over time, it should be quite easy to figure out cow methane emissions. (Almost none when the experiment began; cow eats X pounds of fodder; room has Y pounds of methane Z hours later.) Quite likely you'd be able to peg methane productions to fodder consumption rates and then apply those ratios to cows "in the wild," as it were. Obviously, you'd want to rinse and repeat this experiment with a bunch of cows and different fodders, since there's not going to be a one-size fits all answer from a single combination of variables.

    I will begin to believe in catastrophic anthropogenic climate change when (1) the scientists and individuals promoting this live the life they tell me I have to live; lead by example, (2) the scientists promoting this engage in an open, honest debate with a scientist who does not agree with them, (3) the scientists promoting this always make their raw, unaltered data available as required by the scientific method, and (4) the individuals promoting this stop using derogatory and insulting terms like "holocaust denier" and "flat earther" and "Big Oil funded" and "Koch funded" and so on.

      So, while I have no doubt that real scientists are doing actual work together to find out what the situation really is, there is all this smoke and noise distracting us from the real issues.

      And since anyone call call himself a scientist, and the Internet is the ideal disinformation breeding ground, we have hysterical zealots on both sides that would be ready and willing to in clude beheadings for anyone that disagreed with them.

      How very Zen! The answer is found within the question.

      I would very much appreciate a study that compares the amount of methane emitted by all of the animals that have been hunted to extinction or had their numbers drastically reduced (e.g. bison, whales) with those that have increased in population due to human activity (to include indirect effect such as whitetail deer increases due to predator elimination).

      There is always more to the issue than a single, simple study will be able to take into account (I am being generous here) and there will always be ways to twist the message based on any new data to back up a given political agenda.

      It is clear that humans are capable of changing climate for entire regions and, indeed, the world. History provides us with plenty of examples of this. People in my country who would quibble with this statement are invited to do a little research on the dust bowl. More challenging than altering the world is getting us to agree on which direction we should take it when we do. Perhaps a better question than, "Are we causing things to change?" would be, "How do we want things to end up?"

      Re: Serious question

      Ever heard of evolution, Mr Serious. We got here by exploiting our environments better than than competing individuals, tribes, and species. That's how we are "designed" by evolution to work. Exploiting the environment feels good and natural. That is not really in dispute. Along the way numerous organisms starved, succumbed to disease, were killed by competitors, and, were eaten by predators. Living this way is pretty natural, it doesn't require a big brain. Game theory says that in a variable environment you have more offspring than the environment will support, just in case. The remainder die. Evolution uses death lavishly. If you want to be part of this system, you can, but the odds are you wouldn't last a week. But no one actually wants to live like this. We choose security and creature comforts.

      Somewhere along the way, the strategy of cooperation developed. This meant less stress since you weren't relentlessly competing with everyone, you had a few buddies to hang out with. It also meant that you could achieve new levels of exploitation by acting in groups. Humans are startlingly good at this cooperation thing compared to any other species, except perhaps some social insects (who don't have the smarts we do.)

      The industrial revolution bumped up our ability to exploit the environment by several orders of magnitude again. in fact, to the extent where we can trash the planet, either now or soon, and we are actually are doing this just by being the type of organisms that evolution made us. Just because you are biologically designed to feel like successful exploitation feels good, doesn't mean it will continue to work. Things have changed from when you were genetically constructed. We are not programmed to restrain our exploitation, this function was provided by the environment, in the form of death and suffering when local limits were reached.

      You don't need any funny moral stories about the Koch brothers to get this. This is pretty basic science.

      Right now, we have the choice: go with what biology gave you and reap the result, or take a more enlightened approach, limit your children, be smart with resource usage, preserve the planets biological systems. It's not that hard, it just requires a little thought, and renouncing a bit of your biological programming. Personally, I'm not 100% sure that humans are up to it, but as far as I can see it's certainly possible.

        "Most of my house, right now, is at 2º c"

        This is the sort of thing that people think makes them more energy efficient. It doesn't.

        The energy consumed in heating is driven by the size of the temperature difference that you need to overcome to get the space to a habitable temperature. If you're letting it drop to 2 degrees, you have a very large energy consumption associated with getting it up to temperature later. Once you have a space heated, the most efficient way to manage your heating is to reduce heat losses to an absolute minimum (i.e. insulate and keep the doors shut) so that it retains most of the heat when its not occupied and you only need to heat it by a few degrees next time you go in there.

        Also, if you're only heating the rooms you're using, then you'll suffer massive heat losses through the internal walls as these aren't typically insulated as your external walls are. You therefore end up using a lot more energy to keep the rooms you're using heated as they'll be bleeding heat into the surrounding spaces that you've left cold.

        "I may not the lowest in carbon emissions"

        Indeed, you're not... Probably far from it, if basic thermodynamic principles can be believed!

        One little tip to help your home retain heat when you're out, and thus reduce the amount of energy required to get it back up to temperature when you get home, is to leave all your curtains shut - windows are typically one of the biggest sources of heat loss, so this gives you an extra layer of insulation.

          Re: Serious question

          Plus, as you noted, the energy loss during the time the inside temperature is higher than outside. So, you have to calculate energy loss from keeping rooms heated when not in use, and compare that to the energy needed to get those rooms back to the desired temperature when required; don't forget to include increased loss from adjacent rooms. Only then can you decide whether it's more efficient to keep them heated, unheated, or merely at a lowered temperature.

          40% of my house is currently unheated, and will never be heated because there is no need for it to be habitable, which is not to say that it isn't usable.

            Indeed... there are huge rafts of complicated calculations that you can go into to work out exactly what (in theory) is the most efficient way to control your heating system.

            "40% of my house is currently unheated, and will never be heated because there is no need for it to be habitable, which is not to say that it isn't usable."

            Just bear in mind that heating is not only about making a room habitable - it also protects the contents of the room from potential problems with issues like condensation. If warm humid air from other areas of the house finds its way into an unheated space, it has a nasty habit of depositing its moisture across the first cold surface it comes into contact with.

    if only...

    There are lots of cows on the planet. Seems to me there are far more PEOPLE - many of whom consume some level of vegetarian (i.e. methane producing) diet. The volume of an individual bovine belch or fart is greater than individual human output of the same sort. However, the TOTAL volume is probably higher for humans simply because there are more of us than them. Has any reputable* study attempted to factor that in? I've not seen one but would be interested to do so if someone could provide a link or three.

    My own theory** is that the combined methane output of both humans AND animals, while significant, is dwarfed by that from various industry and nature/weather. Fracking, refining, landfill decomposition, combustion, and volcanic activity, just to name a few of the bigger categories.

    I'm not saying these things are inherently evil. What I AM saying is if methane is problematic, let's identify AND QUANTIFY ALL sources and then RATIONALLY discuss mitigation - without the politically charged hyperbole. Sadly, that last bit will be hardest to achieve. The fervent zealots on BOTH ends of this must be sidelined and told to hold their tongues while more reasonable people identify the real problem(s) and sources of same, in order to craft the BEST solutions that balance the needs of the various interested parties. Only in that way can the problem be solved without reverting to extremist views.

    Significant digits?

    It's been too long since I took advanced statistics, so if someone with more recent knowledge could enlighten me I'd be appreciative.

    How is 4.9 ± 2.6 meaningful? Offering a value to the nearest tenth when uncertainty is ~30 times higher is warped. Shouldn't it be 5 ± 3?

    1. Jim Birch

      Re: Significant digits?

      No, 5 ± 3 is less accurate. Best guess is 4.9 with an uncertainty of 2.6. Even though it's unlikely actually to be 4.9 this is still the most likely figure. Think of a "bell" probability curve: In this case, it is centered on 4.9 not on 5. The spread of the curve is given by the ± 2.6 bit. It's not a spread of 3, it is 2.6.

      If you wanted a rough intuitive figure, 5 ± 3 would be ok. More accurate is 4.9 ± 2.6. This is more likely to be correct. It may be possible to go even further to describe the probability curve shape even further, not just mean and standard deviation (spread), but also skew (asymmetry), kurtosis ("peakedness"), and so on, if your data is good enough.

    But the extracted methane (aka natural gas) can be burned, and is also often used (in the US) as a cheap feedstock for making plastics, fertilizer, etc.

    So if the extracted natural gas is never meant to be released into the atmosphere as free methane, why would they count it as methane (greenhouse gas) emissions?

    Besides that it makes this alarming news that requires more grant money for further research, of course.

        Which is relevant because...?

        Did you ever watch the home improvement shows where pros are doing the installations? They use electronic sniffers to check for leaks, they don't sniff for the smell of the additive.

        Parts per BILLION actually.

        Sorry to interrupt your senseless bashing of Evil Capitalists, but methane is an explosive gas, which also has a tendency to settle in low spaces and fill pits etc.

        Thus those "small" leaks will make pools of explosive gas that can blow up facilities as well as asphyxiating workers, both of which are frowned upon by insurers, stockholders, and governmental regulators.

        Thus any leak so small as to be "too expensive to fix" would have to be truly negligible.

        Also compressed natural gas is stored at around 3000 to 4000 pounds per square inch. Line pressures can also be very high, this is for industrial purposes not home heating. Microscopic pinprick leaks can cut through flesh at those pressures, besides the freezing temperatures. Thus those leaks also get noticed.

        Too expensive to fix, with regulators waiting to hand out fines and sanctions? That'd have to be less methane than from serving burritos at the office party.

            http://www.bls.gov/iif/oshwc/cfoi/cftb0268.pdf

            Total fatal injuries 2012, 4383 cases.

            Oil and gas extraction, Crude petroleum and natural gas extraction, 21 deaths, 0.48%.

            Petroleum and coal products manufacturing, Petroleum refineries, 7 deaths, 0.16%.

            Chemical manufacturing, Basic chemical manufacturing, Petrochemical manufacturing, doesn't exist here as a distinct classification, but one step back the code, from 32511 to 3251, yields 8 deaths, 0.18%.

            In Food manufacturing, Bakeries and tortilla manufacturing was 4 deaths. Soft drink manufacturing had 1 death.

            Looks like refinery is more deadly. However, 4 of the 7 deaths are classified as Transportation incidents. As seen in the All charts, 1992-2012 package, http://www.bls.gov/iif/oshwc/cfoi/cfch0011.pdf, 41% of all Fatal occupational injuries, by Major event, in 2012, were Transportation incidents.

            So refinery work is very safe, as it is highly scrutinized and regulated. Just take care when driving around between facilities, or technically inside of a sprawling plant.

    Ignorant on multiple levels. First, Hydrocarbons are a natural by-product of fission decay of the 2 million cubic miles of Uranium and Thorium contained in Earths 259 trillion cubic mile molten rock mass. As heavy elements decay, the protons and neutrons released form new, 'elemental atoms', which under high heat and pressure form 'elemental molecules' and 'elemental compounds'. Natural gas, is natural and bubbles out of the Earth everywhere, which is why there is Methane in every rock you frack. See "Fracturing the Fossil Fuel Fable" at Principia-Scientific.org.

    Next, there is NO 'greenhouse gas' that has a 'back radiation warming' effect. Carbon Dioxide is impacted by Outgoing Longwave Radiation, an electromagnetic emission moving at the speed of light. In the 14 micron range a CO2 molecule can 'absorb' this energy for one billionth of a second, reducing the photon energy and 'emitting' a longer wavelength, lower energy photon that CANNOT WARM THE EARTH, and cannot be absorbed by additional CO2 molecules, which are merely 'vibrating' in air and NOT warming.

    Finally, Methane has NO ability to do twenty times the MAGIC that CO2 can not do with OLR either. Everything about 'climatology' is a fraud. This elitist created and directed, but taxpayer funded faux science is modern alchemy. Visit FauxScienceSlayer website and read "Becoming A TOTAL Earth Science Skeptic".

      Right....

      ....tell that to the Venusians, who've had a bit of an issue with greenhouse heat retention these last couple of billion years.

      Physicists, chemists, and geologist need to hear about your new discoveries. I look forward to reading your papers when you get them published. I assume your doctorate is in physics?

      Troll with website to promote is still troll

      Do not feed.

    More idiotic pronunciations from "scientists" who should know better and who really do need a career change.

    WTF?

    9.7 billion metric tonnes per year of CO2 released per year. Thats going to have NO effect whatsoever. Can't possible have any effect from 9.7 BILLION TONNES of CO2 released per year. Chump change.

    Going from 320ppm to 400ppm in just 50 years. That all have No affect at all, I mean how could you even think that this gas, that has known properties of trapping solar heat in a system make any difference.

    As for methane, just because the atmospheric levels have increased by 150% since 1750, and it now accounts for 20% of the total radiative force, doesn't mean that ramping up its pollution of our atmosphere will have the slightest bit of a different!

    Just because every time we have high levels of CO2 and CH4 in the atmosphere in Earth's past and its been a lot warmer, doesn't mean this time will be the same. This time it will be different, becuase we want it to be and we believe it will be!

    We will all be fine, nothing to worry about!

      for those who'd like to track green house gas emissions you might like to try here

      Note that we can date the start of mfg of CFC's very accurately and knowing they are key contributors to Ozone depletion we can say that humans can influence global climate on the scale of a human lifetime (albeit a fairly long one).
