Folke Günther Carbon dioxide, deciding for our future Folke Günther FG Holon Ecosystem Consultants Lund Sweden
Folke Günther The climate situation of today is far from satisfying Increasing frequency of abnormal weather situations Destabilised El Niño – Monsoon cycles Increasing risk of non-linear climate changes, ’tipping points’ FG
Folke Günther A simple overwiev of some of the basic stuff 1.On different types of systems 2.On non-linear behaviour of complex systems 3.On carbon chemistry (while you are awake) FG
Folke Günther After that: We move on to the sexier parts of the story 4.An easy way to get rid of carbon dioxide 5.How this could be done easy 6.How to promote massive sequestration FG
Folke Günther A few words on systems theory FG 1
Folke Günther All systems are not the same Simple systems FG
Folke Günther Characteristics of simple systems Can be understod from knowledge of their parts Show predictable behaviour such as: –Trajectories –Calculability –Back-tracking Rather few components make them intuitively understandable FG
Folke Günther All systems are not of the same type Simple systems Complicated systems FG
Folke Günther Complcated systems FG
Folke Günther Complicated systems are of the same type as simple systems Can be understod from knowledge of their parts Therfore: Show predictable behaviour such as: –Trajectories –Calculability –Back-tracking But: Too many components make an intuitive understanding impossible FG
Folke Günther Complex systems FG
Folke Günther Characteristics of complex system Can not be understod from (even total) knowledge of their parts Therfore: Show unpredictable, nonlinear behaviour such as: –Catastrophes –Bifurcations –Emergence Non-linear behaviour is typical for complex systems The system contains more than can be calculated from knowledge of its parts FG Bifurcation (tipping) point
Folke Günther FG Examples of complex systems
Folke Günther Examples of non-linear behaviour in complex systems FG 2
Folke Günther Future Past FG Present Bifurcations (Tipping points): Abrupt changes in complex systems
Folke Günther The melting of the North polar cap –Cause: Decrease of the ice-cap decrease albedo more melting further albedo decrease sweet water release –Possible result: sweet water from the polar cap closes NADW The disruption of the Gulf Stream –Cause: Sweet-water prevents sinking of cold,salt water – no NADW –Ice-age in Northern Europe and North America –cooling (The change to Younger Dryas evolved in about 10 years, lasted 1300 years) Examples of tipping points in the global system FG
Folke Günther The change to cold conditions, during which the surface temperature temperature of the Northern Hemisphere dropped precipitously precipitously (nearly 15ºC in Greenland) in a series of abrupt, decade-scale jumps, due to the loss of the NADW. This abrupt climate change is known as the "Younger "Younger Dryas" Dryas" event, lasting about 1,300 years. FG The Younger Dryas FG
Folke Günther Examples of non-linear behaviour of the global system Methane emissions from the melting tundra –Multiplied greenhouse effect heating More melting, more methane The calving of the Ross-ice –increasing sea level decreased brake 7 m sea level increase within a 20 year period FG
Folke Günther On carbon chemistry FG 3
Folke Günther Carbon has three pricipal chemical constellations 1.The reduced form These compounds are easily oxidized into carbon dioxide FG
Folke Günther Carbon has three pricipal chemical constellations These compounds are stable under normal conditions, and not easily oxidized into carbon dioxide Diamond 1.The reduced form 2.The neutral form FG
Folke Günther Carbon has three pricipal chemical constellations These compounds are stable under normal conditions, and not easily oxidized into carbon dioxide Anthracite, coal The neutral form FG
Folke Günther Coal formation FG
Folke Günther Carbon has three pricipal chemical constellations These compounds are stable under normal conditions, and not easily oxidized into carbon dioxide Charcoal, biochar 2.The neutral form Produced during pyrolysis /C(H 2 O)/ n biomass heating of biomass with reduced oxygen access FG Oxidation resistace time: 50,000 years (Ogawa)

Folke Günther Carbon has three pricipal chemial constellations 3.The oxidized form Sunlight Heat This compound is stable under normal conditions, and need an energy input to be converted into other compounds 1.Heat reflecting 2.= Greenhouse gas Gt ( tonnes) extra produced during industrialisation Carbon dioxide FG
Folke Günther An easy way to catch and get rid of carbon dioxide FG 4
Folke Günther Statement: There is already too much carbon dioxide in the atmosphere You can not solve that problem by releasing less every year You have to remove some of the carbon dioxide How? FG
Folke Günther By that, carbon dioxide is removed from the atmosphere. The process is called carbon sequestration /C(H 2 O)/ n When plants add solar energy to the carbon dioxide molecules, carbon dioxide is converted into biomass FG
Folke Günther However… /C(H 2 O)/ n After a century, or less, the biomass decomposes and releases the carbon dioxide again It is like putting dirt under the carpet. It will reveal… FG
Folke Günther As carbon as charcoal is extremely stable If you bury it in the soil, it stays there for thousands of years (2 000 –> ) FG But…
Folke Günther So, if you convert biomass into charcoal /C(H 2 O)/ n FG
Folke Günther /C(H 2 O)/ n..and bury it into the soil..
Folke Günther Then, you have created a pathway for carbon dioxide into a semi- permanent storage FG
Folke Günther The problem summarized FG 5

Folke Günther FG
Folke Günther Just successive decrease of the emissions, however successful might lead to a cata- stro- phe FG
Folke Günther Successive decrease PLUS sequstration Might solve the pro- blem
Folke Günther Charcoal in the soil is certainly not inactive FG
Folke Günther Terra Preta: A 2000 Year Old Soil Experiment (Steiner, 2002) Man-Made Soil Plots Average size 20 ha Carbon dated at 800 B.C- 500 A.D High Carbon Content (4-20%, typically 9%) Terra preta yields as much as three-fold the surrounding infertile soils. Danny Day, Eprida FG
Folke Günther …about three times crop yield Oxisol (normal rain forest soil) Terra Preta (anthrosol: charcoal enriched oxisol) FG
Folke Günther Charcoal works as an adsorption lattice for micro-organsism and nutrient particles FG
Folke Günther FG
Folke Günther Micro- organisms inside the cavities of a charcoal particle FG
Folke Günther 1 gramme of charcoal might have an inner area of about 400 sq. meters
Ten grammes of charcoal has a surface about the size of a football pitch
Folke Günther Charcoal addition to the soil provides nutrient and water storage for mycorrhizal fungi Their hyphae invade charcoal pores and support spore reproduction Ogawa Kansai Environmental Charcoal is sought out by soil micro- organism Fungi on New Char Fungi on 100 Yr Old Char FG
Folke Günther The plants seek contact with microorganisms Richard Haard, February 12, 2007 FG Charcoal after one year of application
Folke Günther The production of charcoal gives by-products useful for industry and homes FG
Folke Günther Progression of the pyrolysis process Danny Day, Eprida FG
Folke Günther Heat To industry Charcoal production plant Danny Day, Eprida Ammonia FG 40 %
Folke Günther If excess nutrients from settlements are used for carbon loading, this lead to a win-win situation FG
Folke Günther Now, we have lots of good reasons to add charcoal to the soil counteracting the greehouse effect (the ethics of giving ourselves and our children a future) increasing soil fertility (providing more food and a healthier landscape) providing industrial raw material in a situation with fossil fuel scarcity FG
Folke Günther Is that enough? FG
Folke Günther Probably not FG
Folke Günther To really get people’s attention, you have to talk money FG
Folke Günther What about a fair carbon tax? FG
Folke Günther If you want to emit net carbon dioxide: Today’s situation :
Folke Günther And you must have an emission permit FG You have to pay a tax
Folke Günther Tax and permit fund FG $ Payment Permission Emission The PPE model
Folke Günther If you decrease the atmospheric carbon dioxide: FG But:
Folke Günther And you should be the only one who has the right to sell emission permits You should be paid the same amount as the emission tax FG

Folke Günther We burn our petrol candles increasing the climate problems but now we can reverse them turn CO2 to char and bury it into soil Glad tidings we bring To you and your kin Get rid of the very Problem Go bury´ it into soil! Turn CO2 to charcoal Turn CO2 to charcoal Turn CO2 to charcoal And bury it into soil Glad tidings we bring To you and your kin; Get rid of the very Problem Go bury it into soil!
