BOTEs and CO2
So there is a common expression that is getting even more common and more over used called “Back Of The Envelope” which basically is an expression that describes calculations that are very course spatially or vertically OR rough enough that they can be done on the back of an envelope/napkin.
I decided it might be fun to take this concept and apply it to the commonly held belief that man emits 45 Gigatons (1 Gigaton = 1 Billion Tons) per annum. This has been cited in many a popular and scientific paper. Hope you enjoy! I would just note that below there are a bunch of numbers and all assumptions came from some of my Ph.D. work and not out of thin air. It is interesting that my BOTEs while not exactly the same as the IPCC’s independent estimate of 45 Petagrams (1 Pg = 1 Gt) are similar. The issue going forward will be identifying the black-boxes that remain in these equations. (NOTE: All local ecosystem units are in Grams of Carbon per meter squared per year and this is a standard unit of measurement for ecosystem fluxes). Read the rest of this entry »

U.S. Identifies Vast Mineral Riches in Afghanistan
I wonder if Big (What a..) Dick Cheney knew about this one! He couldn’t have otherwise he would have insisted on a more concerted and muscular presence in Afghanistan throughout the War On Terror. Oh well chalk one up to good ol’ fashion Mullah Omar misdirection. Something tells me you will be hearing that Freeport-McMoRan (FCX)out of New Orleans will be getting their grubby nefarious hands involved in this operation given their robust play in the global copper market. Okay you heard it hear folks with FCX’s near monopoly on the global copper market and a large presence in gold we will absolutely see a strong push by them into this nascent opportunity. Just for the record FCX shares are currently trading at $65.26 on the NYSE, traded as high as $87 on January 8th, 11, and April 5th of this year, BUT are far below highs of $114 and 122 on October 10, 2007 and May 19, 2008, respectively. These two dates and the general peak in copper prices happened to coincide with a commercial and residential housing construction boom in China and lead some to believe that we had reached Peak Copper, although the latter has yet to be proven, but it stands to reason we will reach some sort of peak given the finite nature of copper availability, the world’s insatiable appetite for it, and the fact that last I checked creating it out of thin air ain’t an option! I will keep a keen eye on this and I suggest anyone reading this do the same as I demonstrated with an earlier posting on Roche and it’s share skyrocket in the weeks leading up to and after The Great H1N1 scare.
I would just say to the Pashtuns of Southern Afghanistan caveat emptor with Exhibit A being FCX’s Grasberg copper and gold mine in Indonesia, where the natives are restless and growing more so by the day. FCX is determined to see this mine to it’s complete exploitation given that it accounts for $4 Billion of FCX’s $6.5 Billion operating profit (i.e., Nearly 2/3). Some have even decided that peaceful protest is no longer helpful resorting instead to primitive but effective methods of “Message Delivery”. However, when the Indonesian government equips the mine bosses with a security force of 3,000 troops and police the odds are stacked against the indigenous peoples of Papua and Papua New Guinea (See Map courtesy of The Economist).

Forget Peak Oil….Try Peak N, P, and K
Below I have plotted USDA data for Nitrogen (N), Phosphorus (P), and Potasssium (K) applied to crops in the US from 1960 to the present. You will notice two distinct trends (Ex. Fertilizer labels read - for example - 10-10-10 or something like that, which corresponds to 10 Parts N, P, and K Respectively):
1. Nitrogen is and has always been the predominant fraction of fertilizers. However, more importantly N:P ratios have risen at an alarming clip from 1.06 in 1960 to 2.88 in 2007, which translates to 271% in less than 40 years. This in itself is an unsustainable trend that genetic engineering will not be able to offset. Additionally, the ratio of P to K was 134% higher in 1960 with the pivot-point (i.e., more K than P applied) being 1976-1977 (Note: I wonder if it is in any way correlated with the awesome run the Grateful Dead had during that same time frame?).
2. The percent vs. Tons P & K curves, while largely decoupled prior to to 1978 have now converged, which means that more fertilizer needs to be applied - and energy expended - to get the same Energy Return On Investment. This is quite unfortunate given the apparant lake of Global P-Pools and the recent USGS report that quantified global P at 62 Gigatons (ie 1 Billion Tons) and K at 250 Gigatons.
This data demonstrates our reliance on not just Carbon (i.e., Oil) but also N, P, and K alike. It will come to pass that the import of these 3 elements will approach if not surpass that of Oil in the next 50 years mark my words! However, there are tons of ways to ameliorate this trend and they include the application of Industrial Policy to large-scale composting ventures…Not at the Federal level but rather within counties or municipalities. These would produce two sustainable and non-trivial revenue streams via the sale of compost and anaerobic digestion of methane gas. Additionally, these materials could easily be applied to agricultural operations across the country as a dry (No Soluble P or N responsible for eutrophication), nutrient rich, carbon dense amendment. NO ZERO SUM HERE!
My primary concern going forward is what I will call the CNPS Approach, which just means that instead of having such a strong and disproportionate Carbon-Bias policy needs to focus equally on the other two-thirds of the biogeochemical pie, which are Nitrogen (N) and Phosphorus (P) (and Sulfur (S)). Everyone is familiar with the influence of CO2 and the established as well as nascent efforts aimed at monetizing carbon, but with some very simple modeling we could easily link the former to equally important Upward (i.e., CH4, N2O, and N2) and Downward Flows (i.e., NH4, NO3, PO4, and DOC) via emissions and leaching, respectively.

It Aint Just Carbon!
The importance of GDP to economic growth is exceeded by the importance of CNP in nature
It all started with the discovery by American oceanographer Alfred C. Redfield (1890-1963) that the ratio of Carbon (C) to Nitrogen (N) to Phosphorus (P) (C:N:P) of free-floating marine phytoplankton (seston) throughout the world was quite static and reflected the differences of dissolved nutrients in associated waters. The Redfield Ratio as it is known today is 106:16:1 for C:N:P, which means that for every unit of phosphorus there are 16 units of P and 106 units of C. The importance of this discovery for biologists was equated to Avogadro’s number or the speed of light in a vacuum by some scientists according to Sterner & Elser’s book “Ecological Stoichiometry”. Redfield’s Ratio has since been proven an overly generalized depiction of aquatic C:N:P, with an average of 354.4:20.1:1 across all manner of aquatic phytoplankton (See Chart 1).
Out of this discovery grew a very specialized but extremely important discipline called Ecological Stoichiometry, which is essentially a bunch of balanced equations describing how C, N, and P are transferred and transformed in ecosystems. It is quite a revolutionary and at the same time elementary concept, with detractors noting that Ecological Stoichiometry is either too complicated to be understood or too simple to be true. Another way to look at it is that Ecological Stoichiometry gives scientists the opportunity to quantitatively attach elemental importance to the balance of energy and materials. The name stoichiometry comes from the Greek root stoicheion for element and metron meaning measure. Broadly speaking the field focuses on C, N, P, to some extent sulfur (S), and rarely hydrogen (H) and oxygen (O) or as scientists like to call them “The Big Six” for their ubiquity and import in all organic and some inorganic processes. Every constituent of this planet, whether living or dead, flora or fauna, above or belowground, land or sea has a unique stoichiometric ratio of these elements. Organisms must vigilantly maintain these ratios in order to survive, which is also the case for humans (homeostasis). In their book “The Natural Selection of the Chemical Elements: The Environment and Life’s Chemistry” Williams & Fraústo da Silva hypothesized that evolution from early to late prokaryotes, to unicellular eukaryotes, and eventually to complex multicellular eukaryotes was coupled with an increased affinity for homeostasis.
Homeostatic stoichiometry is the struggle to maintain a consistent internal chemistry, while an organism’s environment particularly the elemental makeup of its food fluctuates quite drastically. Some organisms – usually of the sedentary variety – display a flexible Ecological Stoichiometry. Their lack of mobility means they must capitalize on the resources available at any given point in time. Truly homeostatic creatures, whether they be ants (C:N:P = 4.8:12.0:1), snakes (C:N:P = 4.4:3.7:1), or the Dalai Lama (C:N:P = 13.3:6.3:1) are not, in the strict sense, what they eat, rather they maintain their C:N:P by a variety of unsavory and malodorous activities we won’t expand on here for fear of offending the faint of heart. Needless to say organisms that must maintain a narrow C:N:P will go to great lengths in pursuit of that goal even if it means no one to sit next to in the lunchroom. You know that stuff you accidently stepped in while walking down the sidewalk or in your local park? That present Fido left for you has a C:N:P of 9.7:0.9:1.
The question is why should we care about these ratios? Well for the answer let’s look to the most famous examples of balanced chemical reactions, photosynthesis [Eq. 1] and decomposition [Eq. 2]. After all when you peel away the layers of scientific mumbo-jumbo this is what Ecological Stoichiometry is all about. If you are starting to have horrible images of your Intro Organic Chemistry class now would be a good time to stop reading. Are you still here? Good. These two reactions drive plant growth [Eq. 1] and decay of everything from tree leaves (C:N:P = 18.6:8.2:1) to septic waste (C:N:P = 12.0:2.7:1). These reactions and those that produced the Redfield Ratio rely on what is called the Law of Definite Proportions.
The importance of the “Big Six” in nature is not hard to find. One need not look further than Adenosine Tri (ATP) and Diphosphate (ADP) the primary energy transfer molecules in cells for the importance of phosphorus, while sulfur is crucial to amino acids (i.e. cysteine) the primary precursors of proteins. Researchers have shown that the Stoichiometric formula for humans in number of atoms is:
H375,000,000O132,000,000C85,700,000N6,430,000Ca1,500,000P1,020,000S206,000
Na183,000K177,000Cl127,000Mg40,000Si38,600Fe2,680Zn2,110Cu76I14Mn13
F13Cr7Se4Mo3Co1
Thus, we humans have a “Big Six” H:O:C:N:P:S Stoichiometry of 2.8:1.5:13.3:6.3:5.0:1. This may seem confusing but understanding how these elements flow into and around the human body or for that matter ecosystems tells us a great deal about the so-called “velocity of elements”. Many reading this have heard about the “velocity of money” in recent years and the importance of keeping the flow of money brisk and consistent. Well the same is true of elements and Ecological Stoichiometry is an important tool in determining where elements are backed-up or where they are moving too fast to be utilized. Two interconnected examples of the human condition’s influence on Ecological Stoichiometry are the Haber-Bosch process that fixes nitrogen gas to produce ammonia for N, P, and Potassium (K)-rich fertilizers and the Gulf Coast algal blooms in the US that have created consistent and ever expanding deadzones in the waters off the United State’s Gulf Coast. The latter is a direct function of excessive fertilizer application and manure production in the Mississippi River watershed, with manures having C:N:P of 20.3:7.0:1 and most fertilizers either having equal parts N:P:K (10:10:10) or an excess of P (10:20:10). Thus, Gulf Coast’s aquatic ecosystems are experiencing an increase in the velocity of Ecological Stoichiometry – specifically P – via the Mississippi river, which is leading to increases in algal production and decay all of which deplete the waters of oxygen.
Plants and animals adhere to relatively strict C:N:P (:S), because in theory they are trying to fulfill their maximum growth potential, even though such conditions in actuality might be completely illusory. Living beings want to find that stoichiometric “Sweet Spot”. Ecological Stoichiometry explains why we crave certain foods and can’t stand the sight of others. Ecological Stoichiometry, and specifically the C:N:P:S ratio, is a field of study and a natural process that will receive increasing attention in the coming years given the fact that humans are rapidly depleting the world’s supply of P, with 62 Gigatons remaining according to the USGS’ most recent estimates.
In addition, this ratio and its variability is responsible for phenomena such as acid rain in the northeastern US and Europe, and groundwater contamination in and around areas of heavy agriculture. Scientists have known since Redfield and earlier the importance of understanding the interconnectedness of the “Big Six” and more specifically C, N, P, and S. In 2000 Falkowski and colleagues compared natural and human-induced changes in the stoichiometry of earth and found that the change due to anthropogenic causes was 13%, 108%, 400%, and 113% for C, N, P, and S, respectively. Thus, our fascination with Carbon Capture and Storage (CCS) may be at best myopic and at worst dangerous. Forget the GDP what is your country or state’s CNP?

Misdirected Attention
From an interesting article by Joschka Fischer on Project Syndicate:
Quite simply the reply to this is that while Sunni v. Shia may be the short-term cyclical conflict of most importance it is clear from this reader’s perspective that the long-term structural problem is the Kurdish Northeast (Large concentrated oilfields) v. the predominantly Arab rest of Iraq (Small dispersed oilfields). The Trigger Line as this separation is known will prove a chronic issue and one that no amount of troops, drones, or Maliki/Obama DoubleSpeak will resolve.
Nuance is the name of the game in Iraq and the quicker we in the US brush up on it the quicker we will be equipped to hold our politicians feet to the fire on the off chance they show their faces around town. I would imagine the heat will turn up even more when water becomes more restricting…Again a short-term cyclical (Oil) v. long-term structural (Water) paradox, only this one will be a matter of life or internal combustion. In the words of Hindu priest Avimukteshwaranand Saraswati “Without electricity, you can survive. One can’t survive without water…”

The True Cost of Coal!
Clean Energy, Clean Coal, Foreign Oil, Middle East Instability, blah blah blah blah blah.
The 2 graphs presented here derived from the US Mine Health & Safety Administration show the true cost of coal. Since data was first recorded back in the 1930s we have lost at least (ie Average Annual Derivation) 420,960 men due to coal mine fatalities and 25,633, 151 have been injured. As to the severity of the latter I wasn’t able to get my hands on how many resulted in men that were Functionally Dead. With more and more union busting and people like Don Blankenship the owner of Massey Energy the company that oversaw the Upper Big Branch mine in West Virginia making no bones about his distaste and most likely hatred of unions fatalities will rise in my opinion. Yes mechanization and strip-mining has resulted in a decline in fatalities but there has been - in recent years - an increase in large and broadly fatal “accidents”. The Upper Big Branch was a non-union mine thanks to Mr. Blankenship’s machinations. I am not promoting across-the-board unionization but I am worried that erosion of unions where their presence is required may prove economically costly to miners and in the worst case scenario Upper Big Branch Reduxes throughout Appalachia. There may be clean ways to burn coal but it’s extraction is dirty on so many levels not least of which is the fact that it robs communities of their fathers, brothers, uncles, little league coaches, and more importantly their collective spirit. West Virginians and coal mining communities writ large consist of proud, determined, stubborn, and resourceful people. However, the Paradox of Plenty (ie, The Resource Curse) caught them off-guard with the speculative and nefarious vultures swooping in to promise riches that have yet to be delivered. We need to stop stigmatizing these communities and start infusing them with capital aimed at a more diversified economic portfolio. I have been to these communities and they are desperate to decouple themselves from Carbonaceous Robber Barons like Don Blankenship.
Enjoy the data I think the figures speak for themselves.

Geoengineering Delays the Inevitable
The following is from last week’s Economist:
“Geoengineering is an umbrella term for large-scale actions intended to combat the climate-changing effects of greenhouse-gas emissions without actually curbing those emissions. Like genetic engineering was in the 1970s, the very idea of geoengineering is controversial. Most of those who fear climate change would prefer to stop it by reducing greenhouse-gas emissions. Geoengineers argue that this may prove insufficient and that ways of tinkering directly with the atmosphere and the oceans need to be studied. Some would like to carry out preliminary experiments, and wish to do so in a clear regulatory framework so that they know what is allowed and what is not.”
What Geoengineering really is is an ingenious group of scientific avenues that will allow society writ large to shrug off it’s (our) responsibilities and hand the myriad of them to future generations. I absolutely believe in some of the techniques/concepts that fall under the Geoengineering umbrella BUT only if society is willing to embrace significant across-the-board electrical, consumption, and natural resource stewardship austerity measures. Otherwise Geoengineering allows us to circumvent a much deserved bout of self-flagellation. When the facts change we must change our mind. Aside from an unfortunate obfuscation of the data at the University of East Anglia the facts have changed for the worse ergo - Geoengineering aside - it is time for us to change our minds and embrace a Blended Climate Change Amelioration Portfolio (BCCAP). This will include anathema (i.e. Nuclear, Geoengineering, Genetic Engineering) to some environmentalists - including myself - but in return it must include the aforementioned flagellation and a bullish embrace of wind, CH4 digestion, ecosystem appreciation vis a vis development or agribusiness, and biofuels that embrace the role of plant-root carbon sequestration.

How bout this eye-catcher from the Environmental Law Institute.
It shows US Energy Subsidies, with $2.3 Billion to Carbon Capture and Storage, $12.2 Billion to Traditional Renewables, $16.8 to Corn Ethanol, and $70.2 Billion to Traditional Fossil Fuels (energy_subsidies_black_not_green1). I wonder how these numbers will change with the recent hydraulic fracturing love affair and the Marcellus/Bakken Shale formations in the Northeast and Upper Midwest Respectively. Another example of a 5:1 Ratio here in the US (Okay 5.75:1 you get the point!).
The prevalence of the 5:1 Ratio here in the US is quite worrisome given where we see it (i.e. See previous posts).

How bout them apples!
I love it when 1+1 = 3
This figure comes from the truly noble work of Charles Duhigg at The Times. He has been grinding away at the data and the latest piece in this series “Rulings Restrict Clean Water Act, Foiling E.P.A.” along with the articles in the series. I wonder what the math will add up to given the recent Citizens United Supreme Court ruling. This whole mess centers on the use or deletion of the word ‘navigable’ when referring to those bodies of water that are or are not under the EPA’s purview. Anyway what we are seeing here is a full-frontal assault on all laws pertaining to common decency with respect to “natural resources”. When the rivers turn red we will have no one to blame but ourselves, because the solutions are out there and the data is sound, but the will is quiescent.
