Is eating no meat actually doing more harm than good?

18 05 2017

I spend more time on the internet arguing wih vegetarians/vegans than any other group of people……  I so wish they would get off their high horses and start supporting farmers who do the right thing…. and that goes for all you meat eaters out there who buy meat from supermarkets….  STOP IT!!

This opinion piece was originally published by Farmdrop on 4th May 2017.


The younger generation are positively redefining the way we see ourselves in relation to food and the environment.

I grew up in the late 1960s and so I consider myself a bit of a hippy. That decade marked a fundamental mind-set shift in the way people saw themselves in relation to the world. At the time, it was difficult to pinpoint where these ideas came from; many of them simply seemed to come through intuition.

I mention this because, for the first time since the late 1960s, I feel like another shift in consciousness is occurring among the younger generation, particularly amongst so called ‘millennials’.

There is a new field of scientific study called epigenetics which shows that all living organisms constantly interact with their external environment and that these influences can prompt changes in gene expression which can be passed down through the generations. Plants, for example, have epigenetic responses to the environment they grow in, as a result of which a plant may have a subtle difference in its genotype from its parents. Even more interestingly, certain epigenetic traits can stay dormant for several generations, only to find full expression at a later time.

So I suspect that the changing shift in consciousness towards food production and sustainability may actually be partly epigenetic. Perhaps the radical energy of the 1960s is now finding expression among millennials, albeit in a slightly different way.

For these reasons, as an organic farmer of almost 45 years, I have never been more optimistic about the future of farming. However, I am growing increasingly concerned about the large number of people turning to diets that may not necessarily be either healthy or sustainable.

If we are to move to a genuinely sustainable food system, then I think we all need to become much better informed about the sustainability or otherwise of different food systems. Only then we will be better placed to challenge the huge amounts of misinformation on so-called sustainable diets which are encouraging people to avoid all meats and animal products, despite the reality that in many (if not most climates and regions) it is difficult to farm in a truly sustainable way without livestock.

What is the problem with food and farming?

It has become a cliché but it’s true: supermarket food is not cheap and comes at a heavy price. The industrial application of nitrogen fertiliser has contaminated our water systems and atmosphere with dangerous nitrates; the subsidised production of fructose corn syrup has driven an increase in obesity and diabetes; and the excessive use of antibiotics in animals has caused a resistance to these drugs amongst humans.

The real problem is that none of the costs of all this damage is charged to the people who use it and, on the other hand, the positive effects of sustainable farming are not supported.

The current policy framework supports a dishonest economic food pricing system, as a result of which, the best business case is for farmers to grow using industrial methods and for retailers to buy the commodity products from industrial farms, process the hell out of them, package them so the consumer knows nothing about their backstory and then make a profit by turning that around.

So we need new incentives and disincentives, which ensure that the polluter pays and those who farm in a truly sustainable way are better rewarded for the benefits they deliver.

But what are the most sustainable farming methods?

There is no doubt that agriculture and farming is one of the most significant contributor towards climate change. Cutting back on the biggest pollutant (man-made fossil fuels) is very important but to actually reverse climate change – take CO2 out of the atmosphere – then we need to change the way we farm, particularly in relation to the way we look after the soil.

This is because organic matter in the soil is a store of carbon, thereby mitigating harmful emissions in the atmosphere. Britain’s soils store around 10 billion tonnes of carbon, which is more than total annual global emissions of carbon dioxide. Moreover, high levels of organic matter are also the basis for soil fertility, releasing nutrients for healthy plant growth and ultimately food. In other words, the amount of organic matter present in the soil is essential, both for combating climate change and ultimately improving our health.

The problem is that industrial farming methods have depleted organic matter in the soils. In the East of England, around 84% of the land’s carbon rich soil has been lost and continues to disappear at a rate of 1 to 2cm per year. That represents an enormous amount of CO2 released into the atmosphere.

Sustainable food systems are therefore about much more than simply avoiding nasty chemicals and antibiotics, they are about building organic matter in the soil through crop rotation and mixed farming practices.

It is possible for farmers to reduce the emissions from agriculture by re-introducing rotations in the way they use their land – introducing a grass and clover phase that builds soil organic matter, which is then grazed by ruminant animals on rotation, who fertilise the soil further, and results in an ability to grow healthy crops.

According to the International Panel on Climate Change, it is estimated that 89% of all agricultural emissions can be mitigated by improving carbon levels in the soil.

How can you have the most healthy and sustainable diet?

Everyone, at least in principle, wants to eat a healthy and sustainable diet, but we are all very confused about how to do it. If you asked 10 people what the most sustainable and healthy way to eat was then you would probably get 10 different answers. A few might say vegetarian or vegan (the numbers eating a vegan diet has increased by 360% in the last decade) but I think that a large scale switch towards vegetarianism may not necessarily be compatible with sustainability.

In my opinion, many people have been led astray by bad science. The tools used by scientific researchers in the past, and whose published papers have prompted changes in people’s diets, were not based on sound science. It was said that red meat and animal fats should be avoided, both because they are unhealthy and because ruminant animals (cows and sheep) are largely responsible for harmful methane emissions.

But it turns out that neither of those positions are necessarily true.

The study that prompted Governments in Britain and the United States to recommend people to reduce their intake of fats was not based on solid evidence. It is this study that encouraged the food industry to replace fats with added sugars, and we are only now understanding the damage these do to our health.

And the studies that recommended a reduction in red meat consumption on grounds of reducing its environmental impact only look at certain factors in isolation rather than the whole food system. Land-use is often considered as bad in all instances, even though raising livestock is sometimes the only productive land use option available. In roughly two thirds of the UK’s agricultural land area is grass and the only way we can turn that into a good soil that stores carbon and grows healthy crops is to have ruminant animals grazing on a rotation system to fertilise the ground.

These flawed assumptions have had significant consequences for the way people eat. Beef production has halved since the 1980s and the consumption of lamb, arguably the most sustainable grass-fed meat for the land, has plummeted. While new evidence is now showing that animals fats are good for our health and cattle grazed in the right way can actually reduce carbon emissions by creating fertile soils.

Where do we go from here?

My message is simple: a healthy diet should work backwards from the most sustainable way to farm, and that ideally means eating the foods produced by mixed farms using crop rotations which include a fertility building phase, usually of grass and clover grazed by cows and sheep, but also pastured pigs and poultry.

Industrial farming has been an extractive industry. We have dined out on the natural capital of the soil that previous generations have laid down for us. We need to fix that because the environment in which a plant or animal is produced goes a long way to determine its nutrient value when consumed by humans.





It’s simple. If we can’t change our economic system, our number’s up

I occasionally publish articles by George monbiot. At times I have labelled them ‘Monbiot at his best’, even if I disagreed with bits of it….. but this time, he utterly nails it. There’s very little regulars to this site will learn from this, but it is a good piece of writing, and it needs to be shared far and wide, because we truly need this revolution. It’s two years old, but even more relevant now than when he wrote it.

Found on the Guardian’s website…..

'The mother narrative to all this is carbon-fuelled expansion. Our ideologies are mere subplots.'

Let us imagine that in 3030BC the total possessions of the people of Egypt filled one cubic metre. Let us propose that these possessions grew by 4.5% a year. How big would that stash have been by the Battle of Actium in 30BC? This is the calculation performed by the investment banker Jeremy Grantham.

Go on, take a guess. Ten times the size of the pyramids? All the sand in the Sahara? The Atlantic ocean? The volume of the planet? A little more? It’s 2.5 billion billion solar systems. It does not take you long, pondering this outcome, to reach the paradoxical position that salvation lies in collapse.

To succeed is to destroy ourselves. To fail is to destroy ourselves. That is the bind we have created. Ignore if you must climate change, biodiversity collapse, the depletion of water, soil, minerals, oil; even if all these issues miraculously vanished, the mathematics of compound growth make continuity impossible.

Economic growth is an artefact of the use of fossil fuels. Before large amounts of coal were extracted, every upswing in industrial production would be met with a downswing in agricultural production, as the charcoal or horse power required by industry reduced the land available for growing food. Every prior industrial revolution collapsed, as growth could not be sustained. But coal broke this cycle and enabled – for a few hundred years – the phenomenon we now call sustained growth.

It was neither capitalism nor communism that made possible the progress and pathologies (total war, the unprecedented concentration of global wealth, planetary destruction) of the modern age. It was coal, followed by oil and gas. The meta-trend, the mother narrative, is carbon-fuelled expansion. Our ideologies are mere subplots. Now, with the accessible reserves exhausted, we must ransack the hidden corners of the planet to sustain our impossible proposition.

On Friday, a few days after scientists announced that the collapse of the west Antarctic ice sheet is now inevitable, the Ecuadorean government decided toallow oil drilling in the heart of the Yasuni national park. It had made an offer to other governments: if they gave it half the value of the oil in that part of the park, it would leave the stuff in the ground. You could see this as either blackmail or fair trade. Ecuador is poor, its oil deposits are rich. Why, the government argued, should it leave them untouched without compensation when everyone else is drilling down to the inner circle of hell? It asked for $3.6bn and received $13m. The result is that Petroamazonas, a company with a colourful record of destruction and spills, will now enter one of the most biodiverse places on the planet, in which a hectare of rainforest is said to contain more species than exist in the entire continent of North America.

Almost 45% of the Yasuni national park is overlapped by oil concessions.

The UK oil firm Soco is now hoping to penetrate Africa’s oldest national park, Virunga, in the Democratic Republic of Congo; one of the last strongholds of the mountain gorilla and the okapi, of chimpanzees and forest elephants. In Britain, where a possible 4.4 billion barrels of shale oil has just been identified in the south-east, the government fantasises about turning the leafy suburbs into a new Niger delta. To this end it’s changing the trespass laws to enable drilling without consent and offering lavish bribes to local people. These new reserves solve nothing. They do not end our hunger for resources; they exacerbate it.

Look at the lives of the super-rich, who set the pace for global consumption. Are their yachts getting smaller? Their houses? Their artworks? Their purchase of rare woods, rare fish, rare stone? Those with the means buy ever bigger houses to store the growing stash of stuff they will not live long enough to use. By unremarked accretions, ever more of the surface of the planet is used to extract, manufacture and store things we don’t need. Perhaps it’s unsurprising that fantasies about colonising space – which tell us we can export our problems instead of solving them – have resurfaced.

As the philosopher Michael Rowan points out, the inevitabilities of compound growth mean that if last year’s predicted global growth rate for 2014 (3.1%) is sustained, even if we miraculously reduced the consumption of raw materials by 90%, we delay the inevitable by just 75 years. Efficiency solves nothing while growth continues.

The inescapable failure of a society built upon growth and its destruction of the Earth’s living systems are the overwhelming facts of our existence. As a result, they are mentioned almost nowhere. They are the 21st century’s great taboo, the subjects guaranteed to alienate your friends and neighbours. We live as if trapped inside a Sunday supplement: obsessed with fame, fashion and the three dreary staples of middle-class conversation: recipes, renovations and resorts. Anything but the topic that demands our attention.

Statements of the bleeding obvious, the outcomes of basic arithmetic, are treated as exotic and unpardonable distractions, while the impossible proposition by which we live is regarded as so sane and normal and unremarkable that it isn’t worthy of mention. That’s how you measure the depth of this problem: by our inability even to discuss it.





Consuming our future…….

Hat tip to Sam who left the link to this “Must Hear” podcast.

From the ABC RN website….:

Only lowering our living standards will achieve sustainable growth. That’s the message from Satyajit Das, a former financier who anticipated the GFC. Debt, energy consumption, housing affordability or superannuation – it’s all based on a financial system that’s in fact a completely fictional model. This model was always doomed to fail – eventually.

Beyond growth as we know it – How can we stop consuming our future? was presented by The Rescope Project. 4 February 2017

And the oil rout continues unabated..

26 02 2017

Paul Gilding, whose work I generally admire, has published a new item on his blog after quite some time off. “It’s time to make the call – fossil fuels are finished. The rest is detail.” Sounds good, until you read the ‘detail’. Paul is still convinced that it’s renewable energy that will sink the fossil fuel industry. He writes…..:

The detail is interesting and important, as I expand on below. But unless we recognise the central proposition: that the fossil fuel age is coming to an end, and within 15 to 30 years – not 50 to 100 – we risk making serious and damaging mistakes in climate and economic policy, in investment strategy and in geopolitics and defence.

Except the fossil fuel age may be coming to an end within five years.. not 15 to 30.

The new emerging energy system of renewables and storage is a “technology” business, more akin to information and communications technology, where prices keep falling, quality keeps rising, change is rapid and market disruption is normal and constant. There is a familiar process that unfolds in markets with technology driven disruptions. I expand on that here in a 2012 piece I wrote in a contribution to Jorgen Randers book “2052 – A Global Forecast” (arguing the inevitability of the point we have now arrived at).

This shift to a “technology” has many implications for energy but the most profound one is very simple. As a technology, more demand for renewables means lower prices and higher quality constantly evolving for a long time to come. The resources they compete with – coal, oil and gas – follow a different pattern. If demand kept increasing, prices would go up because the newer reserves cost more to develop, such as deep sea oil. They may get cheaper through market shifts, as they have recently, but they can’t keep getting cheaper and they can never get any better.

In that context, consider this. Renewables are today on the verge of being price competitive with fossil fuels – and already are in many situations. So in 10 years, maybe just 5, it is a no-brainer that renewables will be significantly cheaper than fossil fuels in most places and will then just keep getting cheaper. And better.

With which economy Paul….? Come the next oil crisis, the economy will simply grind to a halt. Paul is also keen on electric cars….

Within a decade, electric cars will be more reliable, cheaper to own and more fun to drive than oil driven cars. Then it will just be a matter of turning over the fleet. Oil companies will then have their Kodak moment. Coal will already be largely gone, replaced by renewables.

When the economy crashes, no one will have any money to buy electric cars. It’s that simple….. Peak Debt is only just starting to make its presence felt…:

The carnage continues in the U.S. major oil industry as they sink further and further in the RED.  The top three U.S. oil companies, whose profits were once the envy of the energy sector, are now forced to borrow money to pay dividends or capital expenditures.  The financial situation at ExxonMobil, Chevron and ConocoPhillips has become so dreadful, their total long-term debt surged 25% in just the past year.

Unfortunately, the majority of financial analysts at CNBC, Bloomberg or Fox Business have no clue just how bad the situation will become for the United States as its energy sector continues to disintegrate.  While the Federal Government could step in and bail out BIG OIL with printed money, they cannot print barrels of oil.

Watch closely as the Thermodynamic Oil Collapse will start to pick up speed over the next five years.

According to the most recently released financial reports, the top three U.S. oil companies combined net income was the worst ever.  The results can be seen in the chart below:

Can the news on the collapse of the oil industry worsen…..? You bet……

According to James Burgess,

A total of 351,410 jobs have been slashed by oil and gas production companies worldwide, with the oilfield services sector bearing much of this burden, according to a new report released this week.

The report, based on statistical analysis by Houston-based Graves & Co., puts the number of jobs lost in the oilfield services sector at 152,015 now—or 43.2 percent of the global total since oil prices began to slump in mid-2014.

And then there are the bankruptcies……

A report published earlier this month by Haynes and Boone found that ninety gas and oil producers in the United States (US) and Canada have filed for bankruptcy from 3 January, 2015 to 1 August, 2016.

Approximately US$66.5 billion in aggregate debt has been declared in dozens of bankruptcy cases including Chapter 7, Chapter 11 and Chapter 15, based on the analysis from the international corporate law firm.

Texas leads the number of bankruptcy filings with 44 during the time period measured by Haynes and Boone, and also has the largest number of debt declared in courts with around US$29.5 billion.

Forty-two energy companies filed bankruptcy in 2015 and declared approximately US$17.85 billion in defaulted debt. The costliest bankruptcy filing last year occurred in September when Samson Resources filed for Chapter 11 protection with an accumulated debt of roughly US$4.2 billion.

Then we have Saudi Arabia’s decision to cut production to manipulate the price of oil upwards. So far, it appears to have reached a ceiling of $58 a barrel, a 16 to 36 percent increase over the plateau it had been on for months last year. But this has also come at a cost.

The world hasn’t really caught on yet, but OPEC is in serious trouble.  Last year, OPEC’s net oil export revenues collapsed.  How bad?  Well, how about 65% since the oil price peaked in 2012.  To offset falling oil prices and revenues, OPEC nations have resorted to liquidating some of their foreign exchange reserves.

The largest OPEC oil producer and exporter, Saudi Arabia, has seen its Foreign Currency reserves plummet over the past two years… and the liquidation continues.  For example, Saudi Arabia’s foreign exchange reserves declined another $2 billion in December 2016 (source: Trading Economics).

Now, why would Saudi Arabia need to liquidate another $2 billion of its foreign exchange reserves after the price of a barrel of Brent crude jumped to $53.3 in December, up from $44.7 in November??  That was a 13% surge in the price of Brent crude in one month.  Which means, even at $53 a barrel, Saudi Arabia is still hemorrhaging.

Before I get into how bad things are becoming in Saudi Arabia, let’s take a look at the collapse of OPEC net oil export revenues:

The mighty OPEC oil producers enjoyed a healthy $951 billion in net oil export revenues in 2012.  However, this continued to decline along with the rapidly falling oil price and reached a low of $334 billion in 2016.  As I mentioned before, this was a 65% collapse in OPEC oil revenues in just four years.

Last time OPEC’s net oil export revenues were this low was in 2004.  Then, OPEC oil revenues were $370 billion at an average Brent crude price of $38.3.  Compare that to $334 billion in oil revenues in 2016 at an average Brent crude price of $43.5 a barrel…….

This huge decline in OPEC oil revenues gutted these countries foreign exchange reserves.  Which means, the falling EROI- Energy Returned On Investment is taking a toll on the OPEC oil exporting countries bottom line.  A perfect example of this is taking place in Saudi Arabia.

Saudi Arabia was building its foreign exchange reserves for years until the price of oil collapsed, starting in 2014.  At its peak, Saudi Arabia held $797 billion in foreign currency reserves:

(note: figures shown in SAR- Saudi Arabia Riyal currency)

In just two and a half years, Saudi Arabia’s currency reserves have declined a staggering 27%, or roughly $258 billion (U.S. Dollars) to $538 billion currently.  Even more surprising, Saudi Arabia’s foreign currency reserves continue to collapse as the oil price rose towards the end of 2016:

The BLUE BARS represent Saudi Arabia’s foreign exchange reserves and the prices on the top show the average monthly Brent crude price.  In January 2016, Brent crude oil was $30.7 a barrel.  However, as the oil price continued to increase (yes, some months it declined a bit), Saudi’s currency reserves continued to fall.

This problem is getting bad enough that for the first time ever, the Saudi government has, shock horror,  started taxing its people….

Tax-free living will soon be a thing of the past for Saudis after its cabinet on Monday approved an IMF-backed value-added tax to be imposed across the Gulf following an oil slump.

A 5% levy will apply to certain goods following an agreement with the six-member Gulf Cooperation Council in June last year.

Residents of the energy-rich region had long enjoyed a tax-free and heavily subsidised existence but the collapse in crude prices since 2014 sparked cutbacks and a search for new revenue.

How long before Saudi Arabia becomes the next Syria is anyone’s guess, but I do not see any economic scenario conducive to Paul Gilding’s “Great Disruption”. The great disruption will not be the energy take over by renewables, it will be the end of freely available energy slaves supplied by fossil fuels. I believe Paul has moved to Tasmania, in fact not very far from here….. I hope he’s started digging his garden.





Making America great again, and other bullshit……

21 01 2017

nafeezIt appears Nafeez Mosaddeq Ahmed has been making lots of waves lately…. The New York Observer has just run his warning of the probability of a converging oil, food and financial crash in or shortly after 2018 which I discussed here on DTM a few days ago. Not only that, it went viral, hitting the top 20 stories on Medium for several days (at one point hitting number one), and giving him ‘Top Writer’ status on ‘energy’ and ‘climate change’ there….. is the word finally getting out…..?

It gets better….. Nafeez then wrote this via Insurge intelligence in solidarity with the arising people’s movement in the form of the worldwide women’s marches, tying together how the Trumpian inauguration represents at once the culmination of a global war on women, while simultaneously starting a war on the planet.

Nafeez thinks “there is a deep, fundamental but little-understood connection between white supremacist patriarchy and misogyny, and the interlinked environment-economic crisis.” This piece is perhaps the most important – because it highlights the real symbolic meaning of the women’s marches: a planetary declaration of intent to build bridges, not walls.

Then yesterday, Nafeez  wrote another piece for VICE anticipating the Great Orange Face’s ‘America First Energy Plan’, bringing together cutting edge science on why Trump’s fossil fuel madness is doomed to kill the economy.

It simply won’t work, cannot work….. It will backfire. Big time. And it will backfire economically before it even has time to “backfire planetarily” as he so well puts it…… We are already hearing a lot of outrage, rightly so, about the cleansing of the Wipe House website of climate information, and the promotion of this madcap anti-science scheme to burn our planet to hell. We’ll hear less about the science of global net energy decline, which proves decisively that this scheme can simply never work – but you’ll find it here: 

Nafeez begins…..:

As President-elect Trump spearheads plans to boost oil, coal and gas, a major new study by one of the world’s foremost energy experts shows just how dangerous this path would be—not just for the planet, but for the economy.

The new study, just published in January as part of the SpringerBriefs in Energy series, suggests that as long we remain dependent on fossil fuels, economic contraction is inevitable. And while renewable energy offers the only potentially viable future, it is also unlikely to sustain the sort of mass consumerism we are accustomed to—like three or more cars per household, SUVS or massive military projects like aircraft carriers.

The bottom line is that we can’t sustain our present rate of consumption no matter what energy source we rely on. And clinging to oil, gas and coal in the hopes of keeping the endless growth machine alive will be even worse: leading to a spiral of debt and economic recession that has already begun.

Nafeez then introduces his readers to the concept of thermodynamics….. yes, really…!

It all comes down to physics: the laws of thermodynamics. Economies need energy to function. And to grow, they need extra energy to fuel that growth in production and consumption. But as more energy is required just to extract new energy from fossil fuels, there is less “energy surplus” available to continue driving economic growth—to ramp up even more production and consumption. And increasingly, more and more energy is being used just to maintain the existing infrastructure of society as it is, leaving less room for further growth.

“Of perhaps greater concern than the quantity of oil and other energy sources is their declining EROI [energy return on investment]”, writes study author Charles Hall, ESF Foundation Distinguished Professor of Environment Science at the State University of New York. Hall is the founder of the concept of EROI.

Hall’s ground-breaking methodology is now used by scientists around the world to measure the total value of energy a resource can generate. It works by comparing the quantity of energy extracted to the quantity of energy inputted to enable the extraction.

He points out that throughout the energy literature “there is widespread concern that net energy returns (e.g. EROI) for oil and gas are declining and likely to continue declining.” This has economic implications:

We (as in DTM followers) all knew that of course, but it’s interesting that this stuff is actually starting to go viral…..

wheredidgrowthgo

Yes indeed, where did all the growth go…… down the Limits to Growth plughole, that’s where…..

Charlie Hall’s study, Energy Return on Investment: A Unifying Principle for Biology, Economics halleroeibookand Sustainability, clearly shows a correlation between the declining abundance of resources, “as reflected in lower production and EROI for oil and other important fuels”, and the decline of economic growth.

And that gets to the crux of the problem. We need more energy to get more stuff to grow the economy. So what happens when we can’t get as much energy as before? Growth slows.

That’s why Hall fingers the declining EROI of fossil fuels as the key culprit in decreasing rates of production, which in turn has played a key role in the economic slowdown: “Past investments— over the past century— were made at a time when the production of high quality fossil fuels was increasing at rates as high as 5% a year. At the time of this writing they have declined to no more than 1% a year, and the US (and global) economies show similar pattern.”

Hall argues that modern developed economies, with their enormous infrastructures, roads and cities, are rapidly approaching “a stage where all of the available energy is used in ‘maintenance metabolism’ to support the infrastructure that exists.” This leaves less and less energy “available for net growth.”

As I have been saying for a very long time now, the 20th Century was built one brick at a time, as and when it was required, using very cheap and very dense fossil fuels with very high ERoEI. Now we have to replace all the old stuff, more or less all at once (it is getting old now…), and simultaneously build all the new stuff, with low ERoEI energy that is literally costing the Earth.

Make no mistake, America will never be great again………. Trump or no Trump.





Beyond the Point of No Return

4 12 2016

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.

increase-in-carbon-dioxide-from-soils

(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.

The Trouble with Permaculture

4 10 2016

With the recent passing of Bill Mollison, much has been published on the interweb about Permaculture; While Glenda was here for nine days, I didn’t spend much time at this laptop, preferring to help her set her own stamp on the Fanny Farm and using her very able gardening skills to get stuck into some planting…. and fixing the goose tractor in readiness for the acquisition of more birds, but there will be time for that some place else on this site.

Having published Samuel Alexander’s epitaph for Bill Mollison by merely copying and pasting the Conversation article, I didn’t bother following the links therein; luckily, Greg Bell did, and posted a couple in a comment he left here, many thanks Greg…. as he says in his comment, “Those two “here” links to critiques of permaculture are the two most important things I’ve read all year (and they, in turn, link to even more)……

The first link is to Resilience.org and bears the same title as this entry. Fascinating reading indeed, as are the comments below it.
