"The problem is not our understanding of the science or the efficacy of our potential solutions. The problem is human willingness to do the right thing before its too late."

 

 

  We first latched onto the notion of catastrophic climate change back around 1980 when we were a young attorney taking quixotic cases involving impossible-to-rectify injustices like cancers among atomic veterans, trespass of sacred sites or nuclear waste disposal, and shoving those insults under the noses of attorneys-general, judges and justices to try to get a reaction.

Occasionally we would finesse a surprising win and that helped attract donations to keep the enterprise running and the entertainment value high, attracting more donors, and so it went.

One such case was against the deepwell injection of toxic effluent from the manufacture of pesticides and herbicides by agrochemical companies in Mt. Pleasant, Tennessee. The effluent in question had been extracted from an aquifer and tested by State laboratories where was quickly ranked as the most concentrated poison they had ever pulled from the wild. A single green fluorescent drop killed all the fish in the tank. There were 6 billion gallons injected under Middle Tennessee from 1967 to 1980. It made Love Canal look like the kiddie pool.

As we mustered our arguments to go before state regulators and appellate judges, we were compelled to counter some rather absurd arguments being advanced by the mop-up squads of high-priced attorneys for the companies. They said, “Heckfire, Tennessee has plenty of water,” meaning there was no good reason to protect the nonpotable (mineral-rich) waters of the Knox Aquifer a mile down.

Apart from the fact that the Knox is an artesian source of water for area industries and thereby already protected from “contaminants” whether toxic or not by the federal Safe Drinking Water act, we advanced two principal lines of argument, bringing in expert witnesses and entering scientific studies into the record.

Our first line was population growth. Tennessee was growing and what may seem like a lot of water in 1980 may not be nearly enough in 2080. The second line was climate change.

We argued that global warming was advancing, just as scientists had been consistently predicting for the past hundred or more years, and that it would put pressure on water supplies not just in Tennessee, but across the continent.

At that time science suggested warming in the 20th century of about half a degree Celsius. Those were the good old days. Nonetheless, persuading a country judge that global warming was real and something to be concerned about was no mean feat.

 

 

 

 

We had to pull out the big guns. We went to our local congressman and got his assistance to troll the federal agencies for useful studies. We holed up in Vanderbilt science library poring over journals and books on climatology. We spoke to some key figures in the field at that time — Stephen Schneider, Susan Solomon, Kerry Emanuel, Edward A. Martell, Mario Molina — and we assembled that advice into legal briefs and memoranda.

All in all, we scared the bejesus out of ourselves.

The case lingered on for a number of years but by 1985 had been largely resolved by gutsy State regulators, who wrote new rules that essentially prohibited hydrofracking. The companies shut down the injection wells, closed their factories soon after (the phosphate ores that had attracted them in the first place having long since played out and the costs of hauling in by train making the location uneconomical) and moved on. The litigation cost meter ceased running and the death threats stopped. But we were still beset by unshakable malaise.

We had seen the future, and it was different than we had previously imagined. It was not our father’s future.

The materials gathered over the course of ten years were published in our book, Climate in Crisis: The Greenhouse Effect and What We Can Do. The book came out on the heels of two other fine 1989 books that said essentially the same thing: Stephen Schneider’s Global Warming and Bill McKibben’s The End of Nature, all to resounding popular disinterest.

Fast forward a quarter century and we were still very much in a funk about what the future holds. When our granddaughter was born in 2005 we felt very sad for her.

We were still tracking the literature, still going to conferences, still speaking with experts, but until the International Permaculture Conference in Sao Paolo, Brazil in June, 2007 we had not found much to call hope.

Biochar

It was at the Ecocentro do Cerrado that year that we caught a first fleeting glimpse. Andre Soares and his partners were conducting experiments in recreating terra preta do indio – the Amazonian Dark Earths. They were, not coincidentally, massively sequestering carbon while growing wholesome food.

Just over a year later, in September 2008, the Permaculture International Journal sent us to Newcastle, England to report on "Biochar, Sustainability and Security in a Changing Climate,” the 2d International Conference of the International Biochar Initiative, with over 225 attendees from 31 different countries and over 70 presentations. That, and some intervening trips back to Brazil to visit the archaeological sites near Manaus, provided the source material for our 2010 book, The Biochar Solution: Carbon Farming and Climate Change.

For those readers who might be new to biochar, the Virgin Energy Challenge offers this quick synopsis:

 

 

 

Biochar is a relatively low-tech approach inspired by the terra preta soils found in the Amazon basin. These black, fertile soils were created in pre-Columbian times by indigenous farming cultures. They mixed wood char, crushed bone, and manure into the otherwise relatively infertile Amazonian soil to build crop beds. The wood char, though not a fertilizer per se, served to buffer nutrients from the bone meal and manure. It apparently served as a soil analog of a coral reef. Its porous structure and nutrient buffering surface area created a favorable microenvironment for communities of soil fungi and other organisms that aided soil fertility.

Terra preta soils, once well established, appear to be self-sustaining. So long as crop cover protects them from wind and water erosion, they maintain their high level of soil carbon and productivity long after additions of the materials that built them have stopped. In fact they gradually increase in depth as new material composts. In the Amazon basin, thick terra preta soil beds built as far back as 450 BCE remain productive and highly valued by local farmers to this day.

Terra preta soils were initially thought to be peculiar to the warm, wet environment of the Amazon basin. Research has shown, however, that similar results can be obtained in temperate regions by amending soils with formulations of biochar and other ingredients tailored to local soil and crop conditions. The amount of carbon that can potentially be stored in this manner is huge; the amount currently stored as soil carbon has been estimated as 2,300 GT, nearly three times the 800 GT of carbon now present in the atmosphere. If soil carbon could be increased globally by an average of just 10%, it would sequester enough carbon to return atmospheric CO₂ to pre-industrial levels.

The issue with biochar then is not the amount of carbon it could ultimately sequester in the soil; it’s (surprise!) economics. There’s little doubt that a well designed program of soil building, incorporating use of biochar as an element, would be an effective way to sequester carbon while providing long term economic value to farmers. It would boost crop yields while reducing the amount of fertilizer needed. It would also reduce water runoff and nutrient leaching while improving drought resistance. On the other hand, biochar is costly to produce and distribute in the amounts needed, and it may take decades for the considerable investment in soil quality to pay off financially.

The key to success for biochar will come down to technology for producing it from local resources, and dissemination of knowledge for how to employ in in a broader program of soil building. A sense of the complexities can be found in a document from the International Biochar Initiative: Guidelines on Practical Aspects of Biochar Application to Field Soil in Various Soil Management Systems. The three VEC finalists developing biochar display the diversity of product and business strategies possible for addressing these complexities.

There are a few errors in that account, but they are trifling. Biochar is not a “relatively low-tech” approach, it is about as low-tech as you can get. Some Amazonian deposits, similar to those “as far back as 450 BCE,” are ten times older than that. Most estimates put soil carbon at 2500-2700 PgC, not 2300 PgC. You don’t need to increase carbon content to 10 percent globally, 5 percent would probably do it, but remember: we were at 20-plus % soil carbon before the age of agriculture and most soils are hungry to get that back. Building it back with biochar makes a more permanent repair, not just moving the furniture around, as other Virgin Challenge competitors — BECCS (Biomass Energy Carbon Capture and Storage), direct air capture and holistic grazing — do.

Biochar gave us hope, but it did not, in and of itself, solve the climate crisis.  We asked that question at the close of our book — “Can it scale quickly enough?” The answer, from what we have seen at the recent UN climate conferences and the lack of early adoption as the dominant farming paradigm, is — “Probably not.”

The rapid rise of global temperature that began about 1975 continues at a mean rate of about 0.18°C/decade, with the current annual temperature exceeding +1.25°C relative to 1880-1920 and +1.9°C relative to 1780-1880. Dampening effects by the deep oceans and polar ice slow the effects of this change but global temperature has now crossed the mean range of the prior interglacial (Eemian) period, when sea level was several meters above present. The longer temperature remains elevated the more amplifying feedbacks will lead to significantly greater consequences.

While global anthropogenic emissions actually declined in the past decade, there is a lag time for consequences. The rate of climate forcing due to previous human-caused greenhouse gases increased over 20% in the past decade, mainly due to a surge in methane, making it increasingly difficult to achieve targets such as limiting global warming to 1.5°C or reducing atmospheric CO2 below 350 ppm. While a rapid phasedown of fossil fuel emissions must still be accomplished, the Paris Agreement targets now require “negative emissions”, i.e.: extraction of CO2 from the atmosphere.

The first rule of holes is, when you find yourself in one, stop digging. We, the two legged hairless apes, are still digging.

In a recent Soil Day paper presented to the American Geophysical Society and the Society for Ecological Restoration, Harvard professor Thomas Goreau wrote:

 

 

 

“Already we have overshot the safe level of CO2 for current temperature and sea level by about 40%, and CO2 needs to be reduced rapidly from today’s dangerous levels of 400 parts per million (ppm) to pre-industrial levels of around 260 ppm.”

Goreau, citing the work of John D. Liu and ourselves, provided his prescriptions:

 

 

 

"Current rates of carbon farming at typical current levels would take thousands of years to draw down the dangerous excess CO2, but state of the art methods of soil carbon sequestration could draw it down in as little as decades if the percentage of long lived carbon is raised to as little as about 10%."

Here we note that Dr. Goreau’s arithmetic is much better than the 4 pour 1000 or Holistic Management calculations we criticized last week. Goreau has distinguished labile carbon from “long lived carbon” and not limited land area just to existing farms. He advocates 10 percent rather than 4 tenths of a percent. He continues:

 

 

 

While all soils can, and must, be managed to greatly increase soil carbon there are two critical soil leverage points that will be the most effective to reverse global climate change, namely increasing the two most carbon-rich soils of all, Terra Preta, and wetlands. These are the most effective carbon sinks for very different reasons, Terra Preta because it is 10-50% carbon by weight, composed of biochar, which can last millions of years in the soil. Wetland soils can be up to pure organic matter, because lack of oxygen prevents organic matter decomposition. Wetlands contain half of all soil carbon, and half of that is in marine wetlands, which occupy only about 1% of the Earth’s surface but deposit about half of all the organic matter in the entire ocean. Yet they are often ignored in both terrestrial and marine carbon accounting. Marine wetland soils have more carbon than the atmosphere, but are being rapidly destroyed in the misguided name of “economic development.”

Biochar is what soil scientists call “recalcitrant carbon,” meaning that it does not readily combine with other elements unless high temperature heat or some other catalyst is present. Consequently, as much carbon as can be gleaned from the normal “labile” carbon cycle and turned into recalcitrant carbon can be kept from the atmosphere. We know from the experience of the terra preta soils that it doesn’t just stay out of the atmosphere for a few seasons, it traps carbon in the soils for thousands of years.

Switching to renewable energy will not arrest climate change. None of the schemes that involve planting trees can succeed unless they also include biochar. None of the claims of Allan Savory, Joel Salatin or the Holistic Management movement for mob grazing, or any of the claims related to organic, no-till, animal-drawn carbon farming by Eric Toensmeier, Michael Pollan, Vandana Shiva and others pencil out to reverse climate change unless you include biochar. Even then, the area required for biochar-augmented conversion of land-use, farming and forestry is massive — something like 7-10 Spains per year, and maybe more. Anything less than that and the ship goes down.

 

 

 

When we first grasped this in Brazil in August 2006, it provided our first “ah ha!” moment. But then we concluded it likely can’t scale fast enough, by gradual adoption through word of mouth or a few good books, to prevent Near Term Human Extinction. In October 2007 we called that our "Houston Moment," not in the sense that "Houston we have a problem" but because we were in Houston at an ASPO meeting when it dawned on us — it may already be blown. The death sentence for our species — in the next century if not this one — could have been handed down even before we were born.

The problem is not the science or the efficacy of the solution. The problem is human willingness to change. There also seems to be something called profit that always complicates matters. We will tackle that, and offer some possible ways forward, in our coming posts.

"They have given up their banana and avocado farm in Africa and hope to make a go of it in a land where they do not recognize the trees and have a bit of trouble understanding the local dialect."

 

  We are midway through #REX3 — a 10-day advanced permaculture design workshop with our friends Darren Doherty and Cliff Davis here in Southern Tennessee. The site this year is the newly acquired farm of an emigrant family in the rolling hills of Maury County, just about 20 miles from The Farm community.

For those not familiar with the changes going on in the southern regions of Africa, a bit of history might be helpful. The British took control of the Cape of Good Hope in 1806 in order to prevent it from being occupied by the French during the Napoleonic Wars. Dutch-speaking Afrikaners who had been there more than a century chaffed under British authority and didn’t like being forced to speak English, so they migrated inland and although the British recognized the independence of the South African Republic in 1852 and the Orange Free State in 1854, after gold was discovered the Empire returned and reclaimed those regions in the Boer Wars. A visitor from New Zealand described the typical Afrikaner Kraal of that era:

The Boer republics were sparsely populated and most farming communities lived in isolation, linked to each other by crude wagon trails. Following the custom of their forefathers, the Boers believed a farm should be at least 2400 hectares. Boer farms, even those tending livestock, often had no enclosures; the farmhouse would simply be surrounded by open pasture, a few fields of crops and maybe an orchard. The house itself would often be built from clay and usually consisted of two rooms with a thatched roof. The decorations within were modest and the clay floors were routinely smeared with a mixture of cow dung and water to reduce dust.

Of course, the large farms of the Afrikaners did not remain poor. Thanks to slave labor, many generations of farm toil, and the commerce of the British Empire, they grew to be some of the wealthiest and most productive in the world.

Afrikaner history, although now a distant past, was a thorn in the side of the later African anti-apartheid drives of the last century and animosities linger. For a very long time a small white minority had ruled cruelly, and now, finally, majority rule returned. What happened in nearby Zimbabwe is illustrative of what that can mean for the whites.

Like Nelson Mandela and the African National Congress in South Africa, in the white-ruled state of Rhodesia the opposition party ZANU was banned and its leader Robert Mugabe was imprisoned in 1964. In prison Mugabe taught English to his fellow prisoners and earned multiple graduate degrees by correspondence from the University of London. Freed in 1974, he went into exile in Zambia and Mozambique where he built the resistance movement. Later, with support of British negotiators, the new state of Zimbabwe was given majority rule and in 1980 it elected Mugabe, who has been president ever since and has no intended successors.

Mugabe worked to convince his country’s 200,000 whites, including 4,500 commercial farmers, to stay. Then, in 1982, Mugabe sent his North Korean-trained Fifth Brigade to smash dissent. Over five years, an estimated 20,000 civilians were killed and many whites were dispossessed of their farms with no advance notice. In 2000 Mugabe rewrote the Zimbabwean constitution to expand the powers of the presidency and legitimize seizures of white-owned land. The country’s commercial farming collapsed, triggering years of hyperinflation and food shortages in a nation of impoverished billionaires.

In recent years the horrors inflicted by Mugabe have been so sadistic that we are left wondering whether he is demented by syphillis. And yet, through all of this, he enjoyed the support of the ANC in South Africa and has widespread approval in the continent. With the death of Mandela, South Africa has begun moving away from the policies of equanimity between races and it has become increasingly difficult for whites to attend universities and obtain professional employment. Which brings us to Tennessee.

The farm where our students are congregating this morning is a lifeboat for this old family of Dutch ancestry. They have given up their banana and avocado farm in Africa and hope to make a go of it in a land where they do not recognize the trees and have a bit of trouble understanding the local dialect. Back in South Africa are a number of relatives who look towards this young couple and their Tennessee farm as Noah’s Ark in event of a hard rain coming.

The REX advanced course “cuts to the chase” with farm design to assay what the needs are and what strategies will get this ark on a prosperous footing most rapidly. As the Regrarians website describes it:

Today we are on Day 7 – Fencing. Tomorrow we get to speak about biochar and carbon farming and are looking forward to that part.

As we walked the high ridges of this farm we happened upon an old cemetery, overgrown with vines, its raised crypts caving in, its carvings fading. We posted a photo of one stone on Instagram and someone was kind enough to provide the reference to the verse, which is by poet Felicia Dorothea Hemans (1793-1835). It is called The Hour of Death.

Leaves have their time to fall
And flowers to wither at the north wind’s breath
And stars to set, but all
Thou hast all seasons for thine own, o Death

In many ways this family is lucky. They sensed the north wind’s breath and got out before the knock on the door in the night. They cashed in and took the value of their previous farm with them. All across Europe and the Middle East, changing climate and conflicts over dwindling resources — effects of the population bomb long ago forecast —  are sending waves of penniless and desperate refugees fleeing with nothing at all, just the clothes on their backs.

With the increase of global climate weirding we sometimes get the sense that we may be entering a time without reliable seasonality. There is only one name for that. Death.

In the end, there is no refuge. There is just this one blue marble in space. Either we begin to steward the land the way this workshop of Darren’s teaches, or it will heat up, dry out and support no one.

Alternatively, we can school ourselves with methodologies such as these and live on a garden planet once more, keeping our numbers and demands in harmony with her natural abundance.

Is it even a serious choice?

"The COP agreed that the era of fossil energy is over. That is no longer in question. It will end by 2050, if not sooner. The question is how, and the Paris Agreement leaves that to fairy dust."

  At 7:27 pm Paris time (ECT), the President of the COP, French Foreign Minister Laurent Fabius, gavelled the Paris Agreement home. The crowd stood, applauded and whooped. The text is here: http://unfccc.int/resource/docs/2015/cop21/eng/l09.pdf

Success, it seemed to us, came because of the unions. They were not dockworkers or ironmongers. They were unions of countries with brands that read like corporate logos: AOSIS, ALBA, G77 Plus, High Ambition, the Like-Minded in favor of Kyoto Annexes, stealth-OPEC. No single effort could broker a deal unless it got the big unions on board. In the end ALBA and stealth-OPEC were too small to matter. The Like-Minded splintered in favor of the Ambitious. AOSIS and G77, the Climate Vulnerable Forum, and High Ambition ruled.

In their 2 minute closer, Philippines noted it was the first time that the concept of Climate Justice appears in a legally binding document. In time, they hinted, the United States and other overdeveloped countries will be made to pay reparations to those who will lose all or substantial parts of their counties, including all that high-priced real estate in Rio, Capetown, Shanghai and Hong Kong. Consumerist Empires built on fossil energy may have an unusually large credit card statement coming at the end of the billing cycle.

Pluses and minuses in the new agreement: the 1.5C target is in, thanks to the efforts of UNFCCC head Christina Figueres to give a voice to civil society in these corridors. Five-year 'stocktakes' (Websters Dictionary please take note) — reassessment of progress and commitments — are in. Full phase-out of fossil energy by 2050 is not, but that door is not entirely closed and may be reopened at Marrakech next year.

"Each Party’s successive nationally determined contribution will represent a progression beyond the Party’s then current nationally determined contribution and reflect its highest possible ambition, reflecting its common but differentiated responsibilities and respective capabilities, in the light of different national circumstances."

What the text mandates, which is actually significant, is to "achieve a balance between anthropogenic emissions by sources and removals by sinks of greenhouse gases in the second half of this century, on the basis of equity, and in the context of sustainable development and efforts to eradicate poverty."

Decarbonization by 2050 is no longer just a t-shirt. Now it's international law.

Bill McKibben said:

“Every government seems now to recognize that the fossil fuel era must end and soon. But the power of the fossil fuel industry is reflected in the text, which drags out the transition so far that endless climate damage will be done. Since pace is the crucial question now, activists must redouble our efforts to weaken that industry. This didn’t save the planet but it may have saved the chance of saving the planet.”

350.org Executive director, May Boeve said:

“This marks the end of the era of fossil fuels. There is no way to meet the targets laid out in this agreement without keeping coal, oil and gas in the ground. The text should send a clear signal to fossil fuel investors: divest now.

The final text still has some serious gaps. We’re very concerned about the exclusion of the rights of indigenous peoples, the lack of finance for loss and damage, and that while the text recognizes the importance of keeping global warming below 1.5 degrees C, the current commitments from countries still add up to well over 3 degrees of warming. These are red lines we cannot cross. After Paris, we’ll be redoubling our efforts to deliver the real solutions that science and justice demand.”

The thinktank E3G said,  “The transition to a low carbon economy is now unstoppable, ensuring the end of the fossil fuel age.”

Carbon Tracker said: “Fossil fuel companies will need to accept that they are an ex-growth stocks and must urgently re-assess their business plans accordingly.”

The Guardian called it "a victory for climate science and ultimate defeat for fossil fuels."

One piece of statescraft managed by Obama and Kerry was to neatly skirt what killed Kyoto: the 60 Neanderthals in the US Senate put there by the coal kings Koch Brothers. The New York Times spotted the play and reported:

Some elements of the accord would be voluntary, while others would be legally binding. That hybrid structure was specifically intended to ensure the support of the United States: An accord that would have required legally binding targets for emissions reductions would be legally interpreted as a new treaty, and would be required to go before the Senate for ratification.

Such a proposal would be dead on arrival in the Republican-controlled Senate, where many lawmakers question the established science of climate change, and where even more hope to thwart President Obama’s climate change agenda.
 

***

The accord uses the language of an existing treaty, the 1992 United Nations Framework Convention on Climate Change, to put forth legally binding language requiring countries to verify their emissions, and to periodically put forth new, tougher domestic plans over time.

In just updating regulations enacted under an already ratified treaty, the Paris Agreement bypasses the need for new Senate ratification.

Inside Le Bourget, after the obligatory high fives and selfies, delegates crafted sound bytes for the press and kept the lights on and microphones active past midnight. Outside, 10,000 activists took to the streets to pull a "red line," representing 1.5 degrees, to the Arc de Triomphe.

French President Francois Hollande, who has a gift for hyperbole, said "History is made by those who commit, not those who calculate. Today you committed. You did not calculate." Although not in the way he meant it, this is ironically a first-rate assessment of the Agreement.

There is a quality of awareness among all the delegates to the Paris climate talks that, after 20 years of these discussions, is passing strange. We would not call it a deer-in-the-headlights look, because it is not even quite there yet. Those jockeying for the best outcome for their own economies and constituencies are still quite oblivious to the science of what is transpiring and the seriousness of the threat. They have their noses down in the trough and do not hear the butcher at the barn door.

This should not be surprising. Nowhere in the fossil record is there anything quite like what is transforming the world of humans today. Our physical brains are virtually the same as they were 30,000 years ago, when we were standing upright in the savannah, alert to proximate, not distant, threats and quickly obtained, not slowly exploited, resources.

We make ourselves ignorant in at least three ways: not knowing the basic science of climate change, not knowing what to do about it once we 
become aware of the problem, and being barraged with wrong information about both of those and being unable to distinguish fact from fiction.

We might think that a lamb raised in New Zealand and eaten in London would create more greenhouse gases than one being locally grown, but in the way the world works today, the opposite is true. We might think that going vegan is more climate responsible than raising farmed animals, but because of how pastured animals stock soils with carbon, the opposite can be true. We might think, as climate scientist James Hansen does, that low prices for gas cause more fossil fuels to be burned, but the opposite is true, because low prices keep whole provinces of production from being tapped.

When disciplined and deliberate attempts 
by profit-driven vested interests in the production of 
greenhouse gases cast doubt on science and corrupt politics and the media, grasping these nuances becomes even more difficult.

We are a lucky species in that our optimism is more-or-less hard-wired. People tend to be overly optimistic 
about their chances of having a happy marriage or avoiding illness. Young people are easily lured to join the military, become combat photographers, or engage in extreme-risk sports because they are unrealistically optimistic they can avoid harm. 
Humans are also overly optimistic about environmental risks. Our confirmation bias helps us keep up this optimism even when confronted with scientific truths to the contrary.

The principal outcome is less about the how than about the whether. The COP agreed that the era of fossil energy is over. That is no longer in question. It will end by 2050, if not sooner. The question is how, and the Paris Agreement leaves that to fairy dust.

The Guardian reports:

Throughout the week, campaigners have said the deal had to send a clear signal to global industry that the era of fossil fuels was ending. Scientists have seen the moment as career defining.

Carbon Tracker said:

“New energy technologies have become hugely cost-competitive in recent years and the effect of the momentum created in Paris will only accelerate that trend. The need for financial markets to fund the clean energy transition creates opportunity for growth on a scale not seen since the industrial revolution.”

What will replace fossil energy? The basket of renewables described by Jeremy Leggett in Winning the Carbon War? There is a slight problem there, and one wonders how long it will take for that to catch up to the delegates. Perhaps by the first stocktake, but maybe longer.

The problem, as often described on this site and elaborated in our book, the Post-Petroleum Survival Guide (2006), is net energy, or return on energy investment (EROEI), first elaborated by systems ecologist Howard T. Odum. These days the leading scientists in that field are calling it "biophysical economics."

To put it as simply as possible, the source of almost all our energy is the sun. When the EROEI of a resource is less than or equal to one, that energy source becomes a net "energy sink", and can no longer be used as a source of energy, but depending on the system might be useful for energy storage (for example a battery, or the tidal storage in Scotland). A fuel or energy must have an EROEI ratio of at least 3:1 to be considered viable as a prominent fuel or energy source. This chart shows typical values for various technologies.
 

Right now most of what powers the world comes from the top half of that chart. The Paris agreement suggests that most of what we need by 2050 must be selected from portions of the bottom half of the chart — the so-called "clean" energies." Quoth the prophet, Wikipedia:

Thomas Homer-Dixon argues that a falling EROEI in the Later Roman Empire was one of the reasons for the collapse of the Western Empire in the fifth century CE. In "The Upside of Down" he suggests that EROEI analysis provides a basis for the analysis of the rise and fall of civilizations. Looking at the maximum extent of the Roman Empire, (60 million) and its technological base the agrarian base of Rome was about 1:12 per hectare for wheat and 1:27 for alfalfa (giving a 1:2.7 production for oxen). One can then use this to calculate the population of the Roman Empire required at its height, on the basis of about 2,500–3,000 calories per day per person. It comes out roughly equal to the area of food production at its height. But ecological damage (deforestation, soil fertility loss particularly in southern Spain, southern Italy, Sicily and especially north Africa) saw a collapse in the system beginning in the 2nd century, as EROEI began to fall. It bottomed in 1084 when Rome's population, which had peaked under Trajan at 1.5 million, was only 15,000. Evidence also fits the cycle of Mayan and Cambodian collapse too. Joseph Tainter suggests that diminishing returns of the EROEI is a chief cause of the collapse of complex societies, this has been suggested as caused by peak wood in early societies. Falling EROEI due to depletion of high quality fossil fuel resources also poses a difficult challenge for industrial economies.

When we hear pleas from underdeveloping countries for greater financial assistance to allow them to adapt — meaning building out renewable energy and migrating coastal cities inland — we have to ask ourselves if they really comprehend what they will need to adapt to, and whether any amount of money will ever be enough. The status quo ante – the way things worked before — is gone, and so is the modo omnia futura. One hundred billion dollars per year is not enough to save human beings as a species but asking for more won't help, either. What might help is committing to degrowth, depopulation, and scaling back our human footprint to something closer to what we had coming out of the last Ice Age, before we started building monumental cities, mining metal, and inventing writing. We don't need to abandon writing, but lets get real — those megacities may be unsalvageable on a solar budget.

Dr. Guy McPherson writes:

Astrophysicists have long believed Earth was near the center of the habitable zone for humans. Recent research published in the 10 March 2013 issue of Astrophysical Journal indicates Earth is on the inner edge of the habitable zone, and lies within 1% of inhabitability (1.5 million km, or 5 times the distance from Earth to Earth’s moon). A minor change in Earth’s atmosphere removes human habitat. Unfortunately, we’ve invoked major changes.

This discussion seems strangely absent, despite the pushback against Saudi Arabia and India after they succeeded in excluding the substantive recommendations of the Structured Expert Dialogue from the COP. They were not allowed to dump the provisions on transparency and uniform accounting, although it was not for lack of effort.

Instead, we keep hearing reference to an outdated and unfortunate IPCC number — the bent straw everyone is grasping for — that to have a 50-50 chance of limiting warming to 2°C (itself untenably overheated), cumulative emissions to end of century and beyond must be limited to 1 trillion tonnes of carbon dioxide in total, starting 5 years ago. In that past five years we burned through one tenth – 100 Gt. Most predict that with added growth (a big assumption) we’ll have burned through 75% of this "budget" by 2030 and we’ll bust the budget around 2036. If we cut back, we might have until 2060.

Kumi Naidoo of Greenpeace said, "We have a 1.5C wall to climb but the ladder is not tall enough." But he acknowledged, “As a result of what we have secured here we will win… for us Paris was always a stop on an ongoing journey… I believe we are now in with a serious chance to succeed.”

Glen Peters, scientist at CICERO, said 1.5C effectively requires a fossil fuel phase-out by 2030. He later clarified that was without negative emissions or the immediate introduction of a global carbon price, which are some of the assumptions in 1.5C models. His personal view was chances of achieving 1.5C were “extremely slim.”

Will voluntary pledges, revisited every five years starting in 2023 be enough to cut emissions and hold to the budget? It is the wrong question. That budget does not exist. Closer scrutiny of embedded systemic feedbacks reveal we'd blown though any possible atmospheric buffer zone by the 1970s and have just been piling on carbon up there every since.

The Atlantic today reports:

Recent science has indicated that warming to two degrees, still the stated international red line, might be catastrophic, creating mega-hurricanes and possibly halting the temperate jet stream which waters American and European farmland.

From that perspective, 1.5 degrees is an encouraging, ambitious goal. But it’s also a promise that costs negotiators nothing while indicating great moral seriousness.

Because here’s the thing: The math still doesn’t work. 2015 is the hottest year on measure. Because of the delay between when carbon enters the atmosphere and when it traps heat, we are nearly locked into nearly 1.5 degrees of warming already. Many thought the world would abandon the two degree target at Paris due to its impracticality.

Once we apply honestly science-based Earth system sensitivity at equilibrium, excluding none of the feedbacks and forcings that we know of, we discover we passed the 2°C target in 1978. To hold at 2 degrees we would need to bring CO2 concentration down to 334 ppm, not increase it to 450 as the Paris Agreement contemplates. To hold at 1.5°C we would need to vacuum the atmosphere even lower, to a level last seen some time before mid-20th century.

Outside of elite scientists such as those we've mentioned this past week — Anderson, Schellnhuber, Rockstrom, Hansen, Wasdell, and Goreau — few in Le Bourget seem to grasp some simple arithmetic. And so we are treated to the spectacle of fossil producers like India, Russia, Saudi Arabia and many of the underdeveloping countries demanding more time to fill up the available atmospheric space, when in reality there is none and hasn't been for quite some time.

Some say the UN is hamstrung by multilateral consensus, but voting would be no better. After the COP meeting in Durban, the UNFCCC adopted a traditional South African negotiating format to speed up decision-making and bring opposing countries together. The Guardian's John Vidal explains:

Zulu and Xhosa communities use “indabas” to give everyone equal opportunity to voice their opinions in order to work toward consensus.

They were first used in UN climate talks in Durban in 2011 when, with the talks deadlocked and the summit just minutes from collapse, the South African presidency asked the main countries to form a standing circle in the middle of hundreds of delegates and to talk directly to each other.

Instead of repeating stated positions, diplomats were encouraged to talk personally and quietly about their “red lines” and to propose solutions to each other.

By including everyone and allowing often hostile countries to speak in earshot of observers, it achieved a remarkable breakthrough within 30 minutes.

In Paris the indaba format was used by France to narrow differences between countries behind closed doors. It is said to have rapidly slimmed down a ballooning text with hundreds of potential points of disagreements.

By Wednesday with agreement still far away, French prime minister Laurent Fabius further refined the indaba by splitting groups into two.

“It is a very effective way to streamline negotiations and bridge differences. It has the advantage of being participatory yet fair”, said one West African diplomat. “It should be used much more when no way through a problem can be found.”

What may need to happen next year in Marrakech is that the COP host an indaba with experts both in the climate sciences and in biophysical economics.

What may hold out the best hope lies buried 20 pages in, at Article 4:

In order to achieve the long-term temperature goal set out in Article 2, Parties aim to reach global peaking of greenhouse gas emissions as soon as possible, recognizing that peaking will take longer for developing country Parties, and to undertake rapid reductions thereafter in accordance with best available science, so as to achieve a balance between anthropogenic emissions by sources and removals by sinks of greenhouse gases in the second half of this century, on the basis of equity, and in the context of sustainable development and efforts to eradicate poverty.

Article 5:

1. Parties should take action to conserve and enhance, as appropriate, sinks and reservoirs of greenhouse gases as referred to in Article 4, paragraph 1(d), of the Convention, including forests.

2. Parties are encouraged to take action to implement and support, including through results-based payments, the existing framework as set out in related guidance and decisions already agreed under the Convention for: policy approaches and positive incentives for activities relating to reducing emissions from deforestation and forest degradation, and the role of conservation, sustainable management of forests and enhancement of forest carbon stocks in developing countries; and alternative policy approaches, such as joint mitigation and adaptation approaches for the integral and sustainable management of forests, while reaffirming the importance of incentivizing, as appropriate, non-carbon benefits associated with such approaches.

It is not yet clear whether integrated food and fuel sequenced permaculturally designed forests, composed of mixed aged, mixed species robust ecologies and maximum carbon sequestration though biomass-to-biochar energy and agriculture systems will be scaled fast enough, but these two articles could be the spark they need to spur investment.

As the clock ticked on towards end of day, the leader of the High Ambition group, Tony de Blum, introduced to the plenary an 18-year-old girl from Majuro who spoke of water gradually rising on three sides of her home.

"The coconut leaf I wear in my hair and hold up in my hand is from my home in the Marshall Islands. I wear them today in hope of keeping them for my children and my grandchildren — a symbol, these simple strands of coconut leaves that I wear. … Keep these leaves and give them to your children, and tell them a story — of how you helped my islands and the whole world today. This agreement is for those of us whose identity, whose culture, whose ancestors, whose whole being, is bound to their lands. I have only spoken about myself and my islands but the same story will play out everywhere in the world."
