Adding balance to the meat debate

18 02 2019

Of late, I have seen article after article, video after video, exposing ‘meat eating’ as a culprit for the exploding greenhouse emissions we are experiencing. And when I point out it’s all rubbish, I’m attacked as a climate denier….. ME!  A climate denier…?!

There’s so much to say about this topic, it’s hard to know where to start, but I will just say this; meat consumption is not the issue, the predicament is industrial agriculture, pure and simple…… so instead of blaming animal farming, commentators should be attacking the entrenched conventional farming system that needs to be destroyed.

If you are a vegan or vegetarian, the consumption of your diet is just as harmful as the consumption of unsustainable meat. Are you listening George Monbiot? George is one of those classic deniers of the truth. He recently wrote “76% of farmland is wasted on farming animals”. And what does George know about farming?  Zilch I’ll bet…… because farms that grow meat are incapable of growing anything else, otherwise meat would not be produced there.

When soil incapable of growing edible vegetable matter for people is converted to this use, it’s only possible because of the addition of untold chemicals which, since the beginning of the ‘green revolution’, a completely wrong use of the term ‘green’ by the way…..

This opinion piece by Richard Young was originally published by Triodos Bank here

Grazing animals have shaped the quintessentially pastoral British countryside for thousands of years and play a vital role in sustainable food systems. However, over the last decade or so we’ve been told by a succession of high-profile reports that we have to make drastic cuts in our consumption of meat in order to help limit global warming, biodiversity loss and other agriculture-related problems. This has left many people confused about what they should eat to be healthy and have a sustainable lifestyle.

The authors of these reports, such as the recent EAT-Lancet report, all correctly highlight the problems for humanity caused by a rapidly growing global population, high meat consumption in developed countries and an increasing appetite – or in some cases nutritional need – for meat in many developing countries. However, the focus is always put on cutting out red meat, rather than poultry, and no distinction is made in the way the meat is produced.

The basic reason for this is that all cattle, sheep and other ruminants emit the greenhouse gas methane, while chickens do not. They also convert grain to protein less efficiently than poultry or pigs.

It is predicted that by 2050 another billion tonnes of grain will be needed every year to produce enough meat to feed the global population, something which is clearly unsustainable, since continuous grain production is one of the biggest causes of soil degradation and loss. Indeed, globally, cropland soils continue to degrade as carbon is lost to the atmosphere – 24 billion tonnes of soil is lost annually, over three tonnes for every person on the planet.

However, what the researchers invariably overlook is that this is only an issue in relation to grain-fed cattle, such as those in US feedlots, whose rations consist of maize, soya meal and chopped straw.

In contrast, two-thirds of UK farmland is under grass, in most cases because the land is not suitable for growing crops. The only practical way to get food from this land without causing an environmental disaster is to graze it with livestock. Almost all cattle and sheep in the UK are predominantly fed on grass, grazed in the fields during summer and fed as hay or silage over winter – and the UK has one of the best climates in the world for growing grass. Some of these animals do also get grain, but in many cases this is waste grain, like Brewer’s grain (what’s left after beer making), which humans cannot eat.

Tragically, a high proportion of the UK’s most species-rich grasslands have in the past been ploughed for cropping or resown with ryegrass monocultures. However, all organic and most pasture-fed meat producers include legumes, multiple grass species and herbs in their grazing mixtures. Even many intensive farmers have now been persuaded by agri-environment schemes to restore grassland diversity, with wild flowers and delicate species getting a chance to recover once the use of synthetic fertilisers ceases. This in turn helps to revive the intricate web of life, which begins with microbes, soil spiders and other insects, embraces farmland birds and small mammals, and ultimately sustains us humans.

While over-grazing was encouraged by farm subsidies prior to the early 1990s, some grassland is now under-grazed due to falling demand for lamb. This is a problem because many bird and butterfly species have evolved in tandem with grazing livestock. In fact, both the RSPB and Natural England recognise that grazing animals are essential for sustaining healthy wildlife populations.

But what about methane? The high methane levels in the atmosphere are a significant cause of global warming, yet ruminants are responsible for only 5% of UK anthropogenic greenhouse gas emissions. What’s more, all the carbon in ruminant methane is recycled carbon – grazing animals can’t add more carbon to the atmosphere than the plants they eat take out by photosynthesis. In fact, fossil fuels are not only the main source of carbon dioxide emissions, they are also responsible for a third more methane than ruminants and all the methane from fossil fuels contains additional, ‘fossil’ carbon.

So what meat should we choose to help sustain the planet? It’s not a red versus white issue. The simple answer is that we should eat far less grain-fed meat, be it beef, pork or chicken, instead we should actively seek grass-fed meat and meat from animals supplemented with only small amounts of otherwise waste grain.

While few people yet realise it, we actually need to encourage increased production of grass-fed meat, since the most effective way to restore our degraded arable soils and wild pollinators is to re-introduce grass and grazing animals into cropland rotations.

Meet Joel Salatin……

29 10 2018

I’ve been following Salatin for years, and he is truly inspiring…….  my goal is to run the Fanny Farm as a scaled down version of Polyface Farm……. I do wish he wouldn’t put all ‘greenies’ in the same basket though!

The following post originally appeared on the Polyface Farms Facebook page.

Cows at Polyface Farm. Photo by Amber Karnes.

The recent editorial by James McWilliams, titled “The Myth of Sustainable Meat,” contains enough factual errors and skewed assumptions to fill a book, and normally I would dismiss this out of hand as too much nonsense to merit a response. But since it specifically mentioned Polyface, a rebuttal is appropriate. For a more comprehensive rebuttal, read the book Folks, This Ain’t Normal.

Let’s go point by point. First, that grass-grazing cows emit more methane than grain-fed ones. This is factually false. Actually, the amount of methane emitted by fermentation is the same whether it occurs in the cow or outside. Whether the feed is eaten by an herbivore or left to rot on its own, the methane generated is identical. Wetlands emit some 95 percent of all methane in the world; herbivores are insignificant enough to not even merit consideration. Anyone who really wants to stop methane needs to start draining wetlands. Quick, or we’ll all perish. I assume he’s figuring that since it takes longer to grow a beef on grass than on grain, the difference in time adds days to the emissions. But grain production carries a host of maladies far worse than methane. This is simply cherry-picking one negative out of many positives to smear the foundation of how soil builds: herbivore pruning, perennial disturbance-rest cycles, solar-grown biomass, and decomposition. This is like demonizing marriage because a good one will include some arguments.

Apparently if you lie often and big enough, some people will believe it: Pastured chicken has a 20 percent greater impact on global warming? Says who? The truth is that those industrial chicken houses are not stand-alone structures. They require square miles of grain to be carted into them, and square miles of land to handle the manure. Of course, many times that land is not enough. To industrial farmers’ relief, more often than not a hurricane comes along just in time to flush the toilet, kill the fish, and send pathogens into the ocean. That’s a nice way to reduce the alleged footprint, but it’s devilish sleight of hand with the data to assume that ecological toxicity compensates for the true land base needed to sustain a factory farm.

While it’s true that at Polyface our omnivores (poultry and pigs) do eat local GMO (genetically modified organism)-free grain in addition to the forage, the land base required to feed and metabolize the manure is no different than that needed to sustain the same animals in a confinement setting. Even if they ate zero pasturage, the land is the same. The only difference is our animals get sunshine, exercise, fresh pasture salad bars, fresh air, and a respectful life. Chickens walking on pasture certainly do not have any more leg sprains than those walking in a confinement facility. To suggest otherwise, as McWilliams does, is sheer nonsense. Walking is walking — and it’s generally considered to be a healthy practice, unless you’re a tyrant.

Interestingly, in a lone concession to compassion, McWilliams decries ranging hogs with rings in their noses to keep them from rooting, lamenting that this is “one of their most basic instincts.” Notice that he does not reconcile this moral imperative with his love affair with confinement hog factories. Nothing much to use their noses for in there. For the record, Polyface never rings hog noses, and in the few cases where we’ve purchased hogs with rings, we take them out. We want them to fully express their pigness. By moving them frequently using modern electric fencing, polyethylene water piping, high-tech float valves, and scientifically designed feed dispensers, we do not create nor suffer the problems encountered by earlier large-scale outdoor hog operations 100 years ago. McWilliams has apparently never had the privilege of visiting a first-rate, modern, highly managed, pastured hog operation. He thinks we’re all stuck in the early 1900s, and that’s a shame because he’d discover the answers to his concerns are already here. I wonder where his paycheck comes from?

Then McWilliams moves on to the argument that economic realities would kick in if pastured livestock became normal, driving farmers to scale up and end up right where we are today. What a clever ploy: justify the horrible by eliminating the alternatives. At Polyface, we certainly do not discourage scaling up — we actually encourage it. We think more pasture-based farms should scale up. Between the current abysmal state of mismanagement, however, and efficient operations, is an astronomical opportunity to enjoy economic and ecological advantages. McWilliams is basing his data and assumptions on the poorest, the average or below. If you want to demonize something, always pick the lowest performers. But if you compare the best the industry has to offer with the best the pasture-based systems have to offer, the factory farms don’t have a prayer. Using portable infrastructure, tight management, and techno-glitzy tools, farmers running pastured hog operations practically eliminate capitalization costs and vet bills.

Finally, McWilliams moves to the knock-out punch in his discussion of nutrient cycling, charging specifically that Polyface is a charade because it depends on grain from industrial farms to maintain soil fertility. First of all, at Polyface we do not assume that all nutrient movement is anti-environmental. In fact, one of the biggest reasons for animals in nature is to move nutrients uphill, against the natural gravitational flow from high ground to low ground. This is why low lands and valleys are fertile and the uplands are less so. Animals are the only mechanism nature has to defy this natural downward flow. Fortunately, predators make the prey animals want to lounge on high ground (where they can see their enemies), which insures that manure will concentrate on high lookout spots rather than in the valleys. Perhaps this is why no ecosystem exists that is devoid of animals. The fact is that nutrient movement is inherently nature-healing.

But, it doesn’t move very far. And herein lies the difference between grain used at Polyface and that used by the industry: We care where ours comes from. It’s not just a commodity. It has an origin and an ending, start to finish, farmer to eater. The closer we can connect the carbon cycles, the more environmentally normal we will become.

Second, herbivores are the exception to the entire negative nutrient flow argument because by pruning back the forage to restart the rapid biomass accumulation photosynthetic engine, the net carbon flow compensates for anything lost through harvest. Herbivores do not require tillage or annuals, and that is why all historically deep soils have been created by them, not by omnivores. It’s fascinating that McWilliams wants to demonize pasture-based livestock for not closing all the nutrient loops, but has no problem, apparently, with the horrendous nutrient toxicity like dead zones in the Gulf of Mexico the size of New Jersey created by chemical fertilizer runoff to grow grain so that the life of a beef could be shortened. Unbelievable. In addition, this is one reason Polyface continues to fight for relaxing food safety regulations to allow on-farm slaughtering, precisely so we can indeed keep all these nutrients on the farm and not send them the rendering plants. If the greenies who don’t want historically normal farm activities like slaughter to occur on rural acreage could understand how devastating these government regulations actually are to the environmental economy, perhaps McWilliams wouldn’t have this bullet in his arsenal. And yes, human waste should be put back on the land as well, to help close the loop.

Third, at Polyface, we struggle upstream. Historically, omnivores were salvage operations. Hogs ate spoiled milk, whey, acorns, chestnuts, spoiled fruit, and a host of other farmstead products. Ditto for chickens, who dined on kitchen scraps and garden refuse. That today 50 percent of all the human edible food produced in the world goes into landfills or greenie-endorsed composting operations rather than through omnivores is both ecologically and morally reprehensible. At Polyface, we’ve tried for many, many years to get kitchen scraps back from restaurants to feed our poultry, but the logistics are a nightmare. The fact is that in America we have created a segregated food and farming system. In the perfect world, Polyface would not sell eggs. Instead, every kitchen, both domestic and commercial, would have enough chickens proximate to handle all the scraps. This would eliminate the entire egg industry and current heavy grain feeding paradigm. At Polyface, we only purport to be doing the best we can do as we struggle through a deviant, historically abnormal food and farming system. We didn’t create what is and we may not solve it perfectly. But we’re sure a lot farther toward real solutions than McWilliams can imagine. And if society would move where we want to go, and the government regulators would let us move where we need to go, and the industry would not try to criminalize us as we try to go there, we’ll all be a whole lot better off and the earthworms will dance.

AND here’s a lecture Joel gave in Australia last year……..

Methane and climate: 10 things you should know

15 09 2018

The graph above shows methane concentrations in Earth’s atmosphere over the past 10,000+ years: 8000 BCE to 2018 CE.  The units are parts per billion (ppb).  The year 1800 is marked with a circle.

Note the ominous spike.  As a result of increasing human-caused emissions, atmospheric methane levels today are two-and-a-half times higher than in 1800.  After thousands of years of relatively stable concentrations, we have driven the trendline to near-vertical.

Here are 10 things you should know about methane and the climate:

1. Methane (CH4) is one of the three main greenhouse gases, along with carbon dioxide (CO2) and nitrous oxide (N2O).

2. Methane is responsible for roughly 20% of warming, while carbon dioxide is responsible for roughly 70%, and nitrous oxide the remaining 10%.

3. Methane is a powerful greenhouse gas (GHG).  Pound for pound, it is 28 times more effective at trapping heat than is carbon dioxide (when compared over a 100-year time horizon, and 84 times as effective at trapping heat when compared over 20 years).  Though humans emit more carbon dioxide than methane, each tonne of the latter traps more heat.

4. Fossil-fuel production is the largest single source.  Natural gas is largely made up of methane (about 90%).  When energy companies drill wells, “frac” wells, and pump natural gas through vast distribution networks some of that methane escapes.  (In the US alone, there are 500,000 natural gas wells, more than 3 million kilometers of pipes, and millions of valves, fittings, and compressors; see reports here and here.)  Oil and coal production also release methane—often vented into the atmosphere from coal mines and oil wells.  Fossil-fuel production is responsible for about 19% of total (human-caused and natural) methane emissions.  (An excellent article by Saunois et al. is the source for this percentage and many other facts in this blog post.)  In Canada, policies to reduce energy-sector methane emissions by 40 percent will be phased in over the next seven years, but implementation of those policies has been repeatedly delayed.

5. Too much leakage makes electricity produced using natural gas as climate-damaging as electricity from coal.  One report found that for natural gas to have lower overall emissions than coal the leakage rate would have to be below 3.2%.  A recent study estimates leakage in the US at 2.3%.  Rates in Russia, which supplies much of the gas for the EU, are even higher.  Until we reduce leakage rates, the advantage of shutting down coal-fired power plants and replacing them with natural gas generation will remain much more modest than often claimed.

6. Domestic livestock are the next largest source of methane.  Cattle, sheep,  and other livestock that graze on grass emit methane from their stomachs through their mouths.  This methane is produced by the symbiotic bacteria that live in the guts of these “ruminants” and enable them to digest grass and hay.  In addition, manure stored in liquid form also emits methane.  Livestock and manure are responsible for roughly 18% of total methane emissions.

7. Rice paddy agriculture, decomposing organic matter in landfills, and biomass burning also contribute to methane emissions.  Overall, human-caused emissions make up about 60% of the total.  And natural sources (wetlands, swamps, wild ruminants, etc.) contribute the remaining 40%.

8. There is lots of uncertainty about emissions.  Fossil fuel production and livestock may be responsible for larger quantities than is generally acknowledged.  The rise in atmospheric concentrations is precisely documented, but the relative balance between sources and sinks and the relative contribution of each source is not precisely known.

9. There is a lot of potential methane out there, and we risk releasing it.  Most of the increase in emissions in recent centuries has come from human systems (fossil fuel, livestock, and rice production; and landfills).  Emissions from natural systems (swamps and wetlands, etc.) have not increased by nearly as much.  But that can change.  If human actions continue to cause the planet to warm, natural methane emissions will rise as permafrost thaws.  (Permafrost contains huge quantities of organic material, and when that material thaws and decomposes in wet conditions micro-organisms can turn it into methane.)  Any such release of methane will cause more warming which can thaw more permafrost and release more methane which will cause more warming—a positive feedback.

Moreover, oceans, or more specifically their continental shelves, contain vast quantities of methane in the form of “methane hydrates” or “clathrates”—ice structures that hold methane stable so long as the temperature remains cold enough.  But heat up the coastal oceans and some of that methane could begin to bubble up to the surface.  And there are huge amounts of methane contained in those hydrates—the equivalent of more than 1,000 years of human-caused emissions.  We risk setting off the “methane bomb“—a runaway warming scenario that could raise global temperatures many degrees and catastrophically damage the biosphere and human civilization.

Admittedly, the methane bomb scenario is unlikely to come to pass.  While some scientists are extremely concerned, a larger number downplay or dismiss it.  Nonetheless a runaway positive feedback involving methane represents a low-probability but massive-impact risk; our day-to-day actions are creating a small risk of destroying all of civilization and most life on Earth.

10. We can easily reduce atmospheric methane concentrations and  attendant warming; this is the good news.  Methane is not like CO2, which stays in the atmosphere for centuries.  No, methane is a “short-lived” gas.  On average, it stays in the atmosphere for less than ten years.  Many natural processes work to strip it out of the air.  Currently, human and natural sources emit about 558 million tonnes of methane per year, and natural processes in the atmosphere and soils remove all but 10 million tonnes.  (again, see Saunois et al.)  Despite our huge increase in methane production, sources and sinks are not that far out of balance.  Therefore, if we stop increasing our emissions then atmospheric concentrations could begin to fall.  We might see significant declines in just decades.  This isn’t the case for CO2, which will stay in the atmosphere for centuries.  But with methane, we have a real chance of reducing atmospheric levels and, as we do so, moderating warming and slowing climate change.

A series of policies focused on minimizing emissions from the fossil-fuel sector (banning venting and minimizing leaks from drilling and fracking and from pipes) could bring the rate of methane creation below the rate of removal and cause atmospheric levels to fall.  A more rational approach to meat production (including curbing over-consumption in North America and elsewhere) could further reduce emissions.  This is very promising news.  Methane reduction represents a “low-hanging fruit” when it comes to moderating climate change.

The methane problem is the climate problem in microcosm.  There are some relatively simple, affordable steps we can take now that will make a positive difference.  But, if we don’t act fast, aggressively, and effectively, we risk unleashing a whole range of effects that will swiftly move our climate into chaos and deprive humans of the possibility of limiting warming to manageable levels.  We can act to create some good news today, or we can suffer a world of bad news tomorrow.

Beyond the Point of No Return

Imminent Carbon Feedbacks Just Made the Stakes for Global Warming a Hell of a Lot Higher

Republished from Robert Scribbler’s excellent website……..

If EVER there was a need to start soil farming, this proves it beyond doubt.

“It’s fair to say we have passed the point of no return on global warming and we can’t reverse the effects, but certainly we can dampen them,” said biodiversity expert Dr. Thomas Crowther.

“I’m an optimist and still believe that it is not too late, but we urgently need to develop a global economy driven by sustainable energy sources and start using CO2, as a substrate, instead of a waste product.” — Prof Ivan Janssens, recognized as a godfather of the global ecology field.

“…we are at the most dangerous moment in the development of humanity. We now have the technology to destroy the planet on which we live, but have not yet developed the ability to escape it… we only have one planet, and we need to work together to protect it.” — Professor Stephen Hawking yesterday in The Guardian.


The pathway for preventing catastrophic climate change just got a whole hell of a lot narrower.

For according to new, conservative estimates in a scientific study led by Dr. Thomas Crowther, increasing soil respiration alone is about to add between 0.45 and 0.71 parts per million of CO2 to the atmosphere every year between now and 2050.

(Thomas Crowther explains why rapidly reducing human greenhouse gas emissions is so important. Namely, you want to do everything you can to avoid a runaway into a hothouse environment that essentially occurs over just one Century. Video source: Netherlands Institute of Ecology.)

What this means is that even if all of human fossil fuel emissions stop, the Earth environment, from this single source, will generate about the same carbon emission as all of the world’s fossil fuel industry did during the middle of the 20th Century. And that, if human emissions do not stop, then the pace of global warming of the oceans, ice sheets, and atmosphere is set to accelerate in a runaway warming event over the next 85 years.

Global Warming Activates Soil Respiration Which Produces More CO2

This happens because as the world warms, carbon is baked out of previously inactive soils through a process known as respiration. As a basic explanation, micro-organisms called heterotrophs consume carbon in the soil and produce carbon dioxide as a bi-product. Warmth is required to fuel this process. And large sections of the world that were previously too cold to support large scale respiration and CO2 production by heterotrophs and other organisms are now warming up. The result is that places like Siberian Russia, Northern Europe, Canada, and Alaska are about to contribute a whole hell of a lot more CO2 (and methane) to the atmosphere than they did during the 20th Century.

When initial warming caused by fossil fuel burning pumps more carbon out of the global environment, we call this an amplifying feedback. It’s a critical climate tipping point when the global carbon system in the natural environment starts to run away from us.

Sadly, soil respiration is just one potential feedback mechanism that can produce added greenhouse gasses as the Earth warms. Warming oceans take in less carbon and are capable of producing their own carbon sources as they acidify and as methane seeps proliferate. Forests that burn due to heat and drought produce their own carbon sources. But increasing soil respiration, which has also been called the compost bomb, represents what is probably one of the most immediate and likely large sources of carbon feedback.


(A new study finds that warming of 1 to 2 C by 2050 will increase soil respiration. The result is that between 30 and 55 billion tons of additional CO2 is likely to hit the Earth’s atmosphere over the next 35 years. Image source: Nature.)

And it is also worth noting that the study categorizes its own findings as conservative estimates. That the world could, as an outside risk, see as much as four times the amount of carbon feedback (or as much as 2.7 ppm of CO2 per year) coming from soil if respiration is more efficient and wide-ranging than expected. If a larger portion of the surface soil carbon in newly warmed regions becomes a part of the climate system as microbes activate.

Amplifying Feedbacks Starting to Happen Now

The study notes that it is most likely that about 0.45 parts per million of CO2 per year will be leached from mostly northern soils from the period of 2016 to 2050 under 1 C worth of global warming during the period. To this point, it’s worth noting that the world has already warmed by more than 1 C above preindustrial levels. So this amount of carbon feedback can already be considered locked in. The study finds that if the world continues to warm to 2 C by 2050 — which is likely to happen — then an average of around 0.71 parts per million of CO2 will be leached out of soils by respiration every year through 2050.


(When soils lose carbon, it ends up in the atmosphere. According to a new study, soils around the world are starting to pump carbon dioxide into the atmosphere. This is caused by increased soil respiration as the Earth warms. Over the next 35 years, the amount of carbon dioxide being pumped out by the world’s soils is expected to dramatically increase. How much is determined by how warm the world becomes over the next 35 years. Image source: Nature.)

The upshot of this study is that amplifying carbon feedbacks from the Earth environment are probably starting to happen on a large scale now. And we may be seeing some evidence for this effect during 2016 as rates of atmospheric carbon dioxide accumulation are hitting above 3 parts per million per year for the second year in a row even as global rates of human emissions plateaued.

Beyond the Point of No Return

What this means is that the stakes for cutting human carbon emissions to zero as swiftly as possible just got a whole hell of a lot higher. If we fail to do this, we will easily be on track for 5-7 C or worse warming by the end of this Century. And this level of warming happening so soon and over so short a timeframe is an event that few, if any, current human civilizations are likely to survive. Furthermore, if we are to avoid terribly harmful warming over longer periods, we must not only rapidly transition to renewable energy sources. We must also somehow learn to pull carbon, on net, out of the atmosphere in rather high volumes.

Today, Professor Ivan Janssens of the University of Antwerp noted:

“This study is very important, because the response of soil carbon stocks to the ongoing warming, is one of the largest sources of uncertainty in our climate models. I’m an optimist and still believe that it is not too late, but we urgently need to develop a global economy driven by sustainable energy sources and start using CO2, as a substrate, instead of a waste product. If this happens by 2050, then we can avoid warming above 2C. If not, we will reach a point of no return and will probably exceed 5C.”

In other words, even the optimists at this time think that we are on the cusp of runaway catastrophic global warming. That the time to urgently act is now.

Howdy all.

The state and quality of main stream journalism (MSJ), including that at our own ABC and despite what they might think of themselves, has deteriorated to the point of being totally useless. Instead of news, we get stories about cats in schools, fanfares about stupid celebrities making stupid remarks and any other triviality that might distract their audiences from the real world and the little that does resemble credible news, is either government propaganda, incomplete, misleading or a combination of all three. The credibility of MSJ is now non existent.

The collapse of Venezuela, shattered climate records, the release of Arctic methane and CO2, unsustainable global debt, Bilderberg meetings and the sixth mass extinction event currently under way are never mentioned. Our environment continues to be destroyed, the oceans polluted and fished to exhaustion, finite resources are wasted on corporate profits while poverty and overcrowding due to unsustainable population growth continue unabated and the fault lies squarely with MSJ which, has failed to hold those responsible to account.
Tony Jones, Australia’s most popular TV journalist, is the worst of the lot. For decades he has reveled in his popularity while all that sustains us is destroyed in the pursuit of growth and profit. He and his MSJ peers must change or we can kiss our sorry little behinds goodbye and if they think that they and theirs are somehow going to be exempt from the bloody mess that will inevitably befall us then, they are even more stupid than the ignorant fools who govern us.
Aussie journalists are only slightly more trustworthy than the corporate bought and paid for politicians that they serve. How proud they must be.

How fossil fuel burning nearly wiped out life on Earth – 250m years ago

30 05 2015


Originally published in the Guardian, this article just blew me away, as it seriously contests ideas I had accepted as facts a very long time ago….

Do you want to know the real reason for the advances by Islamic State in Iraq and Syria? Changing light bulbs in America. This is the explanation given by John McCain, Republican chair of the Senate armed services committee. At the weekend he blamed Barack Obama’s inability to magic away Isis on the president’s belief that climate change is “the biggest enemy we have”. Never mind the role of the Iraq war – which McCain supported – in destabilising the region, destroying the Iraqi army and creating the opportunities Isis has exploited. Never mind the propagation of Salafi doctrines by Saudi Arabia, which McCain bravely confronts by grovelling before its tyrants. It’s the Better Buildings Challenge and the Solar Instructor Training Network that allowed Isis to capture Ramadi and Palmyra.

In fact there is a connection, but it strengthens Obama’s contention that “climate change constitutes a serious threat to global security”. One of the likely catalysts for the 2011 uprising in Syria was a massive drought – the worst in the region in the instrumental record – that lasted from 2006 to 2010. It caused the emigration of one and a half million rural workers into Syrian cities, and generated furious resentment when Bashar al-Assad’s government failed to respond effectively. Climate models suggest that man-made global warming more than doubled the likelihood of a drought of this magnitude.

But this is nothing by comparison to the real threats to global security, which make global security, as understood by McCain and Obama, look almost frivolous. As the evidence accumulates, it now seems that climate change was the commonest cause of mass extinction in the Earth’s prehistory.

In the media, if not scientific literature, global catastrophes have long been associated with asteroid strikes. But as the dating of rocks has improved, the links have vanished. Even the famous meteorite impact at Chicxulub in Mexico, widely blamed for the destruction of the dinosaurs, was out of sync by more than 100,000 years.

The story that emerges repeatedly from the fossil record is mass extinction caused by three deadly impacts, occurring simultaneously: global warming, the acidification of the oceans and the loss of oxygen from seawater. All these effects are caused by large amounts of carbon dioxide entering the atmosphere. When seawater absorbs CO2, its acidity increases. As temperatures rise, circulation in the oceans stalls, preventing oxygen from reaching the depths.

The great outgassings of the past were caused by volcanic activity that were orders of magnitude greater than the eruptions we sometimes witness today. The dinosaurs appear to have been wiped out by the formation of the Deccan Traps in India: an outpouring on such a scale that one river of lava flowed for 1,500km. But that event was dwarfed by a far greater one, 190m years earlier, that wiped out 96% of marine life as well as most of the species on land.

What was the cause? It now appears that it might have been the burning of fossil fuel. Before I explain this extraordinary contention, it’s worth taking a moment to consider what mass extinction means. This catastrophe, at the end of the Permian period about 252m years ago, wiped out not just species within the world’s ecosystems but the ecosystems themselves. Forests and coral reefs vanished from the fossil record for some 10 million years. When, eventually, they were reconstituted, it was with a different collection of species which evolved to fill the ecological vacuum. Much of the world’s surface was reduced to bare rubble. Were such an extinction to take place today, it would be likely to eliminate almost all the living systems that sustain us. When plants are stripped from the land, the soil soon follows.

The latest research into the catastrophe at the end of the Permian is summarised in two articles by the geologist John Mason on the Skeptical Science site. The strongest clues all seem to point to the same conclusion: that the extinctions were triggered by the eruption of an igneous belt even bigger than the Deccan plateau: the Siberian Traps. As well as CO2, the volcanoes there produced sulphur dioxide, chlorides and fluorides, causing acid rain and the depletion of ozone.

But because carbon dioxide’s residence time in the atmosphere is greater than that of these other gases, it’s likely to have been the major cause of extinction. The change of state – including a rise in oceanic temperatures of 6-10C – was too sudden and sustained to permit the majority of life forms to adapt. The onset of mass extinction coincides with a giant carbon spike “so distinctive that it serves as a marker-horizon all over the world”.

So where did the carbon dioxide come from? Some of it would have bubbled out of the magma. But, enormous as the eruptions were, this alone seems insufficient to account for either the total volume of emissions or the ratio of isotopes (the different atomic forms) of the carbon entering the atmosphere. Fossil fuel seems to fill the gap.

The volcanoes exploded through the Tunguska sedimentary basin,cooking much of the coal, petroleum and methane it contained. Particles of coal fly ash have been found in rocks as far away as the Canadian Arctic. Rising temperatures might also have destabilised methane hydrates – a frozen form of natural gas – causing the kind of runaway feedback that terrifies some climate scientists today. Yes: the geological record suggests that fossil fuel burning might have eliminated most life on Earth.

And today? According to a paper published in 2013, the current rate of ocean acidification, caused by the burning of fossil fuels, is faster than at any time in the past 300m years. During the Permian mass extinction, the eruption of the Siberian Traps through the Tunguska basin seems to have produced between one and two gigatonnes of carbon dioxide a year. Today fossil fuel burning produces 30 gigatonnes a year.

Isis? Global security? If anyone were to survive a mass extinction on the scale of the Permian catastrophe, they would look back and shake their heads, amazed that we could have considered such issues more important.
