“The path to US$0.015/kWh solar power, and lower” (PV Magazine and GTM Research)

The headline and a page with lots of graphics and associated worksheets come from this PV Magazine article. The underpinning assessment is from GTM Research and their report Trends in Solar Technology and System Prices.

Recall that Natural Gas Combined Cycle, the most efficient natural gas generation process, produces electricity at US$05.5/kWh. The quoted US$0.015/kWh is significantly lower than previous projections. Of course, you’ll get different numbers from the usual suspects. Just to note, nearly every established quasi-governmental organization, e.g., U.S. EIA, the IEA, ISO-NE, etc, have missed the mark on both projecting cost per kWh and penetration of solar PV, both behind-the-meter residential and utility scale.

Sidney, NY: The lead example of how the USA will deal with future coastal and riverine flooding?

From Bloomberg, the story of Sidney, NY, not that far from where I used to live in Endicott, NY.

More than 400 homes and businesses ended up underwater in Sidney, affecting more than 2,000 people. It was months before Spry and her neighbors could move back in. It was also the second time in five years that the Susquehanna had wrecked half the village. People had just finished rebuilding. When Spry walked back into her soggy house, the street outside reeking with the rancid smell of garbage and fuel, she was hit first, she remembers, by the sight of her brand-new hardwood floor, completely buckled.

Spry didn’t want to rebuild again, and neither did local officials; everyone knew the river would keep flooding homes and businesses. So Sidney decided to try something else: It would use federal and state money to demolish Spry’s neighborhood while creating a new one away from the flood plain for displaced residents. Sidney would be on the forefront of U.S. disaster policy, a case study in what’s known as managed retreat—and the many ways it can go wrong.

Until recently, the guiding philosophy behind attempts to protect U.S. homes and cities against the effects of climate change was to build more defenses. Houses can be perched on stilts, surrounded by barriers, buttressed with stormproof windows and roofs. Neighborhoods can be buffered by seawalls for storm surges, levees for floods, firebreaks for wildfires. Defenses are an instinctive response for a species that’s evolved by taming the natural world.

But sometimes the natural world won’t be tamed. Or, more precisely, sometimes engineered solutions can no longer withstand the unrelenting force of more water, more rain, more fires, more wind. Within 20 years, says the Union of Concerned Scientists, 170 cities and towns along the U.S. coast will be “chronically inundated,” which the group defines as flooding of at least 10 percent of a land area, on average, twice a month. By the end of the century, that category will grow to include more than half of the communities along the Eastern Seaboard and Gulf Coast—and that’s if the rate of climate change doesn’t accelerate. In their less guarded moments, officials in charge of this country’s disaster programs have begun to acknowledge the previously unthinkable: Sometimes the only effective way to protect people from climate change is to give up. Let nature reclaim the land and move a neighborhood out of harm’s way while it still is one.

What gives me hope … And it ain’t the small stuff

AS Arman Oganisian of Stable Markets writes “There are no solutions, only trade-offs.” That is a fundamentally engineering attitude.

It is fundamentally about the economics, and, in particular, the dramatic drop in levelized cost of energy for wind and renewables, as well as take-up rates.

But, what’s significant, is that players in the marketplace who ignore, shun, and oppose arguments in court and in the public forum of ideas in favor of regulating Carbon emissions, or assigning producer responsibility to fossil fuel companies for the downstream harm their products do, will rapidly do econotaxis towards these kinds of motivations.

That, as the above video notes, the values of these companies have dropped precipitously in the recent term is highly gratifying.

And, oh, by the way, it serves them right.

But, also, a warning to the environmental community, whether in the United States or elsewhere, if you are really, honestly concerned with this problem, you would do well to set aside your personal and collective egos and work with these organizations, some of which have been your long time enemies, to achieve these goals. These trade-offs are necessary to get there.

And what is more important, getting there? Or achieving your side conditions and side goals, however significant they might be in isolation? If climate change approaches an existential threat, then it should be treated like an existential threat? A safe continuance in an isolated ecosystem of a particular species does not rise to the level of worthiness of measures designed to stop a much bigger calamity.

Grow up.

Oh, and what will happen to fossil fuels?

Sustainable Landscaping

Update: 2018-05-26

It’s not about plants, not entirely. But it seems that, in one agricultural area, pollinators (bees) under stress have ceded their pollinating responsibility to a couple of species of exotic (read invasive) flies. See: J. R. Stavert, D. E. Pattemore, I. Bartomeus, A. C. Gaskett, J. R. Beggs, “Exotic flies maintain pollination services as native pollinators decline with agricultural expansion, Journal of Applied Ecology (British Ecological Society), 22 January 2018. The only thing surprising about that is that people consider it surprising.

Update, 2018-04-29:

While my first thoughts and reasons for this post were simply to collect together a number of links pertaining to an interesting subject, regarding which there appeared to be some controversy, I have received several reactions to the material, many supportive and positive, others strongly adverse. This indicated to me that this is an area worth knowing more about, and, so, I have pulled quote a number of technical articles from the fields of Ecology, Forest Management, and Invasive Species Studies which I am currently reading. I intend to at least supplement the links below with additional ones explaining states of knowledge at present. I may include some comments summarizing what I have read. In other posts, in the future, I may do some modeling along these lines, since diffusion processes modeled by differential equations are of significant interest to me, whether for biological and physical systems, or diffusion of product innovations, via, for instance, the Bass diffusion model. Those results won’t be posted here, though.

Sustainable landscaping as described by Wikipedia, and by Harvard University. See also the Sustainable Sites Initiative. It’s a lot more than eradicating invasive species. In fact, that might be harmful. There’s a lot of questionable information out there, even by otherwise reputable sources like The Trustees of Reservations. See also their brochure on the subject where they recommend various control measures, including chemical, even if it is not their preferred option. There is evidence Roundup (glyphosate) is indeed effective against at least Alliaria petiolata, with little harm for common, commingled biocenostics.

Four inspirational books:

I dove into reading Professor del Tredici’s book as soon as I got my copy. Here is part of what he has to say from pages 1-3:

Perhaps the most well-known example of a “spontaneous” plant is Ailanthus altissima or tree-of-heaven, introduced from China. Widely planted in the Northeast in the first half of the nineteenth century, Ailanthus was later rejected by urban tree planters as uncouth and weedy. Despite concerted efforts at eradication, the tree managed to persist by sprouting from its roots and spread by scattering its wind-dispersed seeds …

Although it is ubiquitous in the urban landscape, Ailanthus is never counted in street tree inventories because no one planted it — and consequently its contribution to making the city a more livable place goes completely unrecognized. When the major of New York City promised in 2007 to plant a million trees to fight global warming, he failed to realize … that if the Ailanthus trees already growing throughout the city were counted he would be halfway toward his goal without doing anything. And that, of course, is the larger purpose of this book: to open people’s eyes to the ecological reality of our cities and appreciate it for what it is without passing judgment on it. Ailanthus is just as good at sequestering carbon and creating shade as our beloved native species or showy horticultural selections. Indeed, if one were to ask whether our cities would be better or worse without Ailanthus, the answer would clearly be the latter, given that the tree typically grows where few other plants can survive.

There is no denying the fact that many — if not most — of the plants covered in this book suffer from image problems associated with the label “weeds” — or, to use a more recent term, “invasive species.” From the plant’s perspective, invasiveness is just another word for successful reproduction — the ultimate goal of all organisms, including humans. From a utilitarian perspective, a weed is any plant that grows by itself in a place where people do not want it to grow. The term is a value judgment that humans apply to plants we do not like, not a biological characteristic. Calling a plant a weed gives us license to eradicate it. In a similar vein, calling a plant invasive allows us to blame it for ruining the environment when really it is humans who are actually to blame. From the biological perspective, weeds are plants that are adapted to disturbance in all its myriad forms, from bulldozers to acid rain. Their pervasiveness in the urban environment is simply a reflection of the continual disruption that characterizes this habitat. Weeds are the symptoms of environmental degradation, not its cause, and as such they are poised to become increasingly abundant within our lifetimes.

(Slight emphasis added by blog post author in a couple of places.)

The fact that ‘r-strategists’ are the best invaders is not surprising because the overwhelming majority of biological invasions take place in human- and/or naturally-disturbed habitats. Our modern landscape is mainly disturbed landscape.

Links with some quotes and discussion:

S. L. Flory, K. Clay, “Invasive shrub distribution varies with distance to roads and stand age in eastern deciduous forests in Indiana, USA”, Plant Ecology, 2006, 184:131-141.

Some quotes:

If roads are important corridors for exotic plants or if roadside edges provide good habitat for exotic plant growth, then one would predict decreased exotic plant density with increased distance to roads. In support, the prevalence and cover of exotic plants has been shown to decline with increasing distance to road in a number of ecosystems.

Independent of distance to road, successional age might determine susceptibility of a community to exotic plant invasions. Young forests typically have higher light levels (Levine and Feller 2004), fewer competitors, and less litter than older forests (Leuschner 2002) while mature forest interiors are known to have lower light availability, cooler temperatures, and higher humidity than forest edges (Brothers and Spingarn 1992). We would therefore expect, based on levels of light penetration and microclimatic conditions, that older forests would have higher densities of invasive shrubs near the forest edge than in forest interiors and fewer invasive shrubs overall due to less recent disturbance events and less favourable environmental conditions. We would also expect that younger forests would show weaker correlations of densities of invasive shrubs with increasing distance to road since light levels are higher throughout young forests. This would result in an interaction between distance to road and forest age.

The goal of this study was to quantify the density of invasive exotic shrubs along roads in eastern deciduous forests of varying successional ages in Indiana. Eastern deciduous forests cover much of the landscape east of the Mississippi River. Most of this region has been fragmented by urban and suburban development and roads such that ninety percent of all ecosystem areas in the eastern US are within 1061 m of a road (Riitters and Wickham 2003). We specifically addressed the following questions (1) Does the density of invasive exotic shrubs decline as the distance to a road increases? (2) Does the relationship between density and distance to road differ among exotic shrub species? and (3) Are invasive exotic shrubs less common in mature forests than in young successional forests? Answers to these questions will help develop a predictive framework for plant invasions and better inform management strategies.

This study suggests that roads may contribute to the spread of invasive plants in eastern deciduous forests. We found a highly significant effect of distance to road over all species and for four of seven individual species … One possible mechanism for high densities of invasive shrubs along roads is that exotic shrub propagules are distributed evenly by birds with respect to distance to road and simply survived at a greater rate near the road due to better growth conditions. These conditions might include higher light conditions or increased nutrient or water availability … Better survival and growth of exotic shrubs might also be due to decreased competition with native understory species. Native species may not survive as well along roadsides where runoff from pollutants and exposure to herbivores is greater … A second possible mechanism is that exotic shrub seeds are distributed by birds and other animals in a pattern that parallels the distribution of shrubs that we found. This would mean that the density of dispersed seeds declines with increasing distance to the nearest road but that survival is unaffected by distance to road. A third possible mechanism is that exotic shrub propagules were initially distributed along roads by animals and vehicles and are invading the forest from the roadside edge.

Successional age has been shown to affect exotic plant establishment in old fields in Minnesota with younger successional aged communities more susceptible to invasions and older communities more resistant (Inouye et al. 1987). Our results show that forest successional age plays a similar role in the distribution of invasive shrubs in eastern deciduous forests with invasive shrubs found in greater densities in young and mid-successional forests than mature forests. This is likely due to a combination of factors including differences in light regimes … Exotic shrubs would have survived and grown much more successfully where they did not have to compete with existing trees or intact forests. This hypothesis could help to explain why we found fewer shrubs near the road in mature forests than young and mid-successional forests.

LLNL Sankey diagram of U.S. national energy flows in 2017: What’s possible, what’s not, and who’s responsible

(Updated, 2018-05-02. See below.)

I love Sankey diagrams, and have written about them with respect to influence of Big Oil on U.S. climate policy, and in connection with what it takes to power a light bulb, providing a Sankey-based explanation for something Professor Kevin Anderson has spoken and written about. Indeed, there’s a wealth of computational capability in R and otherwise, for constructing Sankey diagrams and the like. Here’s a new one from Lawrence Livermore National Laboratory:

(Click on image to see much larger version, for inspection or saving. Use your browser Back Button to return to this blog.)

That’s a lot of energy consumption, and renewables have a long way to go before overtaking it. But, maybe not so much.

First of all, if the solution is, hypothetically, all wind and solar, setting aside storage, nearly all that rejected energy won’t be there. So the actual need isn’t about 98 quads, it’s closer to 31 quads. Call it 35 quads for jollies.

Second, note that wind and solar energy technology are presently on the middle part of the logistic S-curve of growth. (See also diffusion of innovations.) This is a super-exponential region. Call it an exponential region to be conservative. Current estimates place cost cuts in technology for these at 30%-40% per year. Actual adoption meets resistance of regulatory capture and other impediments, and during the last year it was 11%. Clearly with the cost advantages, the motivation is to go faster and, one can argue, the greater the spread between present sources of energy and wind and solar, the lower the “energy barrier” to jump to wind and energy despite other impediments. Translating into time, an 11% per year growth rate is a doubling time of 9 years. But a 30% growth rate is a doubling time of just 3.3 years. Say the doubling time is 4 years.

Third, to get from 3.1 quads to 35 quads is about \pi doublings, and it’s certainly less than 4 doublings.

Fourth, so the really bad news for fossil fuels and all business and people that depend upon them to make a living it that:

  • If the doubling time is 4 years, wind and solar will get to 35 quads in 13 years
  • If the doubling time is 3 years, wind and solar will get to 35 quads in under 10 years
  • If the doubling time is 5 years, wind and solar will get to 35 quads in 16 years
  • And if the doubling time is 9 years, which by all accounts is unduly pessimistic, wind and solar will get to 35 years in under 30 years

Will that be enough to keep us from a +3C world?

Probably not: Too little, too late.

But it’ll happen anyway and it is, as I say, why fossil fuel energy and utilities which depend upon them, natural gas and all, are dead on their feet, and stranded. And any government which puts ratepayer and taxpayer dollars into building out new fossil fuel infrastructure is not only being foolish, they are making the mistake of the century.

As for the +3C climate change outcome? Clearly, that is such an emergency that the only option to address it in time is degrowth, not only cutting back on additional growth. However, there’s no evidence that that is even considered as an option. To the approvers of additional development in suburbs like the Town of Westwood and elsewhere, Conservation Commissions and all, I simply say:

You have a choice: Either manage a restrained and then negative growth plan yourself, or Nature will do it for you.

Simple. The officials responsible for these decisions know and have been warned repeatedly about these outcomes. They are ignoring them. They own the long term results. Remember them.

Update, 2018-05-02

The Trump/Perry Department of Energy with its EIA reports solar energy in the United States grew 32% per annum since 2000. So, per the reasoning able, that’s a doubling time of under 3 years. Moreover, this is based upon a long sampling period, since 2000, so it is not only stable, it is probably conservative.

(reblog) Bill Ritter, Jr, Colorado State University: “Market forces are driving a clean energy revolution in the U.S.”

Transforming U.S. energy systems away from coal and toward clean renewable energy was once a vision touted mainly by environmentalists. Now it is shared by market purists.

Today, renewable energy resources like wind and solar power are so affordable that they’re driving coal production and coal-fired generation out of business. Lower-cost natural gas is helping, too.

I direct Colorado State University’s Center for the New Energy Economy, which works with states to facilitate the transition toward a clean energy economy. In my view, today’s energy market reflects years of federal and state support for clean energy research, development and deployment.

And, despite the Trump administration’s support of coal, a recent survey of industry leaders shows that utilities are not changing their plans significantly.

on turbulent eddies in oceans

Oceanic eddies are not negligible, especially in climate modeling. There’s the work of Dr Emily Shuckburgh of the BAS on this, but more specifically there’s section 6.3.3 of Gettelman and Rood, Demystifying Climate Models: A Users Guide to Earth System Models, 2016, an open source book. Generally speaking, oceans transport otherwise un-transportable heat energy from tropics north. As Gettelman and Rood say, “It is as if the large scales (think of the highway or the concrete drainage ditch) require the small scales to handle the flow (or energy) of the circulation” (6.3.3, on page 97).

And while climate models are the best we’ve got, they need a lot more work, and Gettelman and Rood cover areas for improvement. There’s also:

This is not to say model projections are useless. As many say, Uncertainty is not our friend, and that’s what I mean when I write here and elsewhere that forecasts based upon climate models might well underestimate rates of climate change.

Facts are, especially when used in ensembles, numerical climate models have to be fast enough to be able to be run many times simulating Earth’s climate over many years. Even with the fastest computers and specialized hardware, this means compromises are inevitably necessary. For example, although variable grids are common, these are static, and the best dynamical models of fluids (e.g., FVCOM, and see also) use variable mesh grids where the fineness of the grid gets dropped when gradients have too large magnitudes. On the large specialized hardware, such software architectures are presently unworkable because they mean cores have to communicate with one another too much.

Then there’s the interaction with ice sheets, and various simplifications of oceans.

So, my point is, while I certainly would not feel assured that outcomes could be better than they are projected by CMIP5 going on CMIP6, I wouldn’t feel assured either that they are no worse than the models say.

a microgrid with dynamic boundaries

(Updated 2018-04-05, 23:53 EDT.)

Now here’s a thought: A microgrid with dynamic boundaries.

Original popular article.

Controller design.

Basic ideas were conceived by Nassar and Salama, “Adaptive self-adequate microgrids with dynamic boundaries”:


Intensive research is being directed at microgrids because of their numerous benefits, such as their ability to enhance the reliability of a power system and reduce its environmental impact. Past research has focused on microgrids that have predefined boundaries. However, a recently suggested methodology enables the determination of fictitious boundaries that divide existing bulky grids into smaller microgrids, thereby facilitating the use of a smart grid paradigm in large-scale systems. These boundaries are fixed and do not change with the power system operating conditions. In this paper, we propose a new microgrid concept that incorporates flexible fictitious boundaries: “dynamic microgrids.” The proposed method is based on the allocation and coordination of agents in order to achieve boundary mobility. The stochastic behavior of loads and renewable-based generators are considered, and a novel model that represents wind, solar, and load power based on historical data has been developed. The PG&E 69-bus system has been used for testing and validating the proposed concept. Compared with the fixed bound-
ary microgrids, our results show the superior effectiveness of the dynamic microgrid concept for addressing the self-adequacy of microgrids in the presence of stochastically varying loads and generation.

Applications? Jasper, a sonnenCommunity. That’s an islanded microgrid.

Article about it in PV Magazine.

This is encouraging. Because it means, at least, that if people want grid defection to pursue energy democracy, this new option is moving to a community which is already islanded from the grid. With dynamic boundaries, it’s possible one could dynamically assemble groups of communities during the day. And, in fact, there might be a new business model there: An intelligent, rapidly switchable transmission network that could group, regroup, drop, and reconfigure a number of microgrids, for fees.


Oncor‘s microgrid. (Oncor is a Texas utility!)

I love the litany of limits of the supergrid vision in the following talk by Dr Chris Marnay of Lawrence Berkeley National Laboratory.

I also like the designation of renewable energies as being grid hostile.

Update, 2018-04-05

Siemens, in cooperation with Chicago-based ComEd and the Illinois Institute of Technology (IIT), is working to support microgrids as integral operating components within a 20th century-style command-and-control grid. Note:

The dual-pronged pilot is focused on developing next-generation microgrid controller logic that can handle complex, grid-supportive situations as well as a parallel effort to explore the potential for large volumes of photovoltaic solar on microgrids, when paired with stationary storage. To get the inside scoop on the project, I spoke with vice president of strategy for Siemens Digital Grid, Ken Geisler.

Ultimately, Mr. Geisler envisions the grid of the future as a patchwork of smaller microgrids that all intelligently, intuitively work together, saying “These clusters of resources in a coherent area might be able to support more of what I would call a patchwork quilt of microgrids such that the utility has some level of control that helps offset their costs and manage their rates as well as allows third parties to come in and provide resources at some level like rooftop solar or other microgrids that could pop up for the sole purpose for the C&I industry in the area.”

fossil fuels are done

There’s a discussion way off at Energy Institute at Haas about how unfair solar owners are, under current government policies, to electrical customers who do not have PV accessible.

It’s irrelevant.

Fossil fuels are done, stranded, the walking dead. Boss Trump or no Trump. Clinton or no Clinton.

This is an irreversible, nonlinear phenomenon, an observable of a coupled set of differential equations. It’s inexorable.

And it’s about time.

And it makes sense. Technological innovations at this scale are part of Nature.

forecast for 27th March 2018

Today is the 21st of March, 2018. We are supposed to get our fourth nor’easter tomorrow this late Winter, and the third nor’easter in nearly as many weeks.

ECMWF hosted, in this incarnation, at the Meteocentre UQAM in Montreal created this projection for next Tuesday, the 27th of March:

That’s a low pressure cell off the East Coast, another nor’easter. Except this one has a central pressure about 10 millibars lower than any we’ve experienced so far. Don’t know anything at this range about the nature of the precipitation, or closest approach timing with respect to tide levels.

But, still, this recurrence is getting pretty interesting.

By the way, ECMWF is sometimes referred to as “the European model”. It has a reputation of being pretty good, in large measure, because its ab initio physics are very good.

Sea-level report cards, contingency upon model character, and ensemble methods

Done by the Virginia Institute of Marine Science, new sea-level report cards offer a look at current sea-level rise rates, and projections. What’s interesting to me is making the projections conditional upon the character of the model used to project. In particular, this “character” is there simple — they show differences between linear and quadratic projections — but the 2050 projection is in most cases markedly different depending upon which model is chosen.

This is very good, because it shows how modeling matters, and how, as Tamino and others have noted elsewhere, proper model criticism and treatment of uncertainties are key.

I think the VIMS presentation is exactly right for public consumption.

For a more technical audience, one familiar with, say, the “advanced” level of presentation at SkepticalScience, I am increasingly fond of ensemble methods(*), like spaghetti plots. These are very flexible, and can even support a model averaged version of, say, linear and quadratic projections, even if, I think, neither is necessarily defensible on its own.

and Then There’s Physics does “Talking solutions and motivating action”

And Then There’s Physics does a fine post about scientists “talking about solutions and motivating action”.

But I felt the figure from Dr Glen Peters needed to be updated a bit, with a status briefing. So, below:

The problem isn’t that there aren’t solutions. The problem is that we are rapidly running out of time, and some people still think we have time to consider using, for instance, natural gas as a “bridge fuel”.

And I just discussed what begins to happen if we miss the temperature limit.

Uh, oh: Loss of control ahead …

In the technical summary from the NASA Jet Propulsion Laboratory based at the California Institute of Technology titled “Far northern permafrost may unleash Carbon within decades”,

An excerpt:

Permafrost in the coldest northern Arctic — formerly thought to be at least temporarily shielded from global warming by its extreme environment — will thaw enough to become a permanent source of carbon to the atmosphere in this century, with the peak transition occurring in 40 to 60 years, according to a new NASA-led study.

The study calculated that as thawing continues, by the year 2300, total carbon emissions from this region will be 10 times as much as all human-produced fossil fuel emissions in 2016.

This paper, one of a long series of studies of the permafrost, including field assays of emissions using NASA and other aircraft, is titled:

N. C. Parazoo, C. D. Koven, D. M. Lawrence, V. Romanovsky, C. E. Miller, “Detecting the permafrost carbon feedback: talik formation and increased cold-season respiration as precursors to sink-to-source transitions”, The Cryosphere, 12, 123-144, 2018.

It is the first definitive example of a long held fear apparent to anyone familiar with climate science and who thinks deeply about it. While initial forcings off the climate optimum within which civilization has developed are caused completely and entirely by human emissions and actions, the effects of such emissions are, increasingly, amplified by natural forcings. The most direct one is from water vapor which, due to the Clausius-Clapeyron relation, and the fact that water vapor is itself a greenhouse gas, means, roughly, that for each part of warming due to CO2 emissions there’s a comparable part due to water vapor, resulting in a doubling of effect. As warming progresses, there are stores of organic and other Carbon which are frozen out of circulation and microbial activity because of temperature, principally in polar regions. As the Earth warms — and noting that polar regions, percentage-wise, warm more than temperate or tropical ones — these stores are challenged and, eventually, begin to ferment once more. This results in additional emissions of greenhouse gases, CO2 but sometimes CH4.

The implication of all this is that while, at present, we control nearly all of emissions and could, in principle, reverse them by our choice of energy and other deliberate designs, in time, an increasing fraction of emissions will come from natural sources, temperature dependent, over which we have no control whatsoever. Accordingly, if, someday, humanity wished to contain climate change by reducing emissions, while they could zero their own contributions, as time goes, there is no capability of zeroing these natural ones, because they respond to increased temperatures, and that is all. Even Solar Radiation Management, which, in my opinion, is a really bad idea, basically, in its designs, maintains temperatures at whatever they are, preventing increases. It does not cool Earth’s surface.

What’s worse is that even if humanity decided, because of the consequences, to try to scrub atmosphere of emissions, this project is only reasonable, if astronomically expensive, if human emissions are nearly zeroed. It is not possible to keep up with human emissions as they are at present. Human emissions cannot be zero because of those inherent in agriculture and food production, even if these were managed with vehicles and processes which themselves were zero emitting. Accordingly, to the degree to which natural sources increase and dominate, they might, at some point, render any project for direct capture of CO2 futile, closing the door on our climate fate, even if we wanted to spend huge amounts of financial and human capital to make it happen. This is well beyond the ability of any market incentives or technology or engineering to contain.

Researchers Ben Jones, left, Laurence Plug and Guido Grosse pierce and ignite bubbles of methane gas that are frozen near the surface of a tundra lake on Alaska’s Seward Penisula. Methane has 72 times the heating effect of carbon dioxide (CO2), and its emission from arctic lakes was a major contributor to a period of global warming more than 11,000 years ago Nowhere is the evidence of a heating planet more dramatic than in the polar regions. Over the past 50 years, the arctic has warmed twice as fast as the rest of the globe. (Photo by Luis Sinco/Los Angeles Times via Getty Images)

Thus, humanity could, in these circumstance, lose control. Certainly, such natural sources of emissions will make it increasingly more expensive to manage the effects of our emissions. At some point, we tip into a world which is hurling itself headlong into a climate destiny we cannot even imagine.

This is another, perhaps dominant reasons why keeping mean surface temperature changes to but +2 Celsius is so important.

We’re failing to do that.

Ralph Waldo Emerson’s Letter: “…does this government think that the people of the United States are become savage and mad? ”

From this source, heart-rending.

Letter to Martin Van Buren President of the United States


The seat you fill places you in a relation of credit and nearness to every citizen. By right and natural position, every citizen is your friend. Before any acts contrary to his own judgment or interest have repelled the affections of any man, each may look with trust and living anticipation to your government. Each has the highest right to call your attention to such subjects as are of a public nature, and properly belong to the chief magistrate; and the good magistrate will feel a joy in meeting such confidence. In this belief and at the instance of a few of my friends and neighbors, I crave of your patience a short hearing for their sentiments and my own: and the circumstances that my name will be utterly unknown to you will only give the fairer chance to your equitable construction of what I have to say.

Sir, my communication respects the sinister rumors that fill this part of the country concerning the Cherokee people. The interest always felt in the aboriginal population an interest naturally growing as that decays has been heightened in regard to this tribe. Even in our distant State some good rumor of their worth and civility has arrived. We have learned with joy their improvement in the social arts. We have read their newspapers. We have seen some of them in our schools and colleges. In common with the great body of the American people, we have witnessed with sympathy the painful labors of these red men to redeem their own race from the doom of eternal inferiority, and to borrow and domesticate in the tribe the arts and customs of the Caucasian race. And notwithstanding the unaccountable apathy with which of late years the Indians have been sometimes abandoned to their enemies, it is not to be doubted that it is the good pleasure and the understanding of all humane persons in the Republic, of the men and the matrons sitting in the thriving independent families all over the land, that they shall be duly cared for; that they shall taste justice and love from all to whom we have delegated the office of dealing with them.

The newspapers now inform us that, in December, 1835, a treaty contracting for the exchange of all the Cherokee territory was pretended to be made by an agent on the part of the United States with some persons appearing on the part of the Cherokees; that the fact afterwards transpired that these deputies did by no means represent the will of the nation; and that, out of eighteen thousand souls composing the nation, fifteen thousand six hundred and sixty-eight have protested against the so-called treaty. It now appears that the government of the United States choose to hold the Cherokees to this sham treaty, and are proceeding to execute the same. Almost the entire Cherokee Nation stand up and say, This is not our act. Behold us. Here are we. Do not mistake that handful of deserters for us; and the American President and the Cabinet, the Senate and the House of Representatives, neither hear these men nor see them, and are contracting to put this active nation into carts and boats, and to drag them over mountains and rivers to a wilderness at a vast distance beyond the Mississippi. As a paper purporting to be an army order fixes a month from this day as the hour for this doleful removal.

In the name of God, sir, we ask you if this be so. Do the newspapers rightly inform us? Man and women with pale and perplexed faces meet one another in the streets and churches here, and ask if this be so. We have inquired if this be a gross misrepresentation from the party opposed to the government and anxious to blacken it with the people. We have looked at the newspapers of different parties and find a horrid confirmation of the tale. We are slow to believe it. We hoped the Indians were misinformed, and that their remonstrance was premature, and will turn out to be a needless act of terror.

The piety, the principle that is left in the United States, if only in its coarsest form, a regard to the speech of men, forbid us to entertain it as a fact. Such a dereliction of all faith and virtue, such a denial of justice, and such deafness to screams for mercy were never heard of in times of peace and in the dealing of a nation with its own allies and wards, since the earth was made. Sir, does this government think that the people of the United States are become savage and mad? From their mind are the sentiments of love and a good nature wiped clean out? The soul of man, the justice, the mercy that is the heart in all men from Maine to Georgia, does abhor this business.

In speaking thus the sentiments of my neighbors and my own, perhaps I overstep the bounds of decorum. But would it not be a higher indecorum coldly to argue a matter like this? We only state the fact that a crime is projected that confounds our understanding by its magnitude, a crime that really deprives us as well as the Cherokees of a country for how could we call the conspiracy that should crush these poor Indians our government, or the land that was cursed by their parting and dying imprecations our country, any more? You, sir, will bring down that renowned chair in which you sit into infamy if your seal is set to this instrument of perfidy; and the name of this nation, hitherto the sweet omen of religion and liberty, will stink to the world.

You will not do us the injustice of connecting this remonstrance with any sectional and party feeling. It is in our hearts the simplest commandment of brotherly love. We will not have this great and solemn claim upon national and human justice huddled aside under the flimsy plea of its being a party act. Sir, to us the questions upon which the government and the people have been agitated during the past year, touching the prostration of the currency and of trade, seem but motes in comparison. These hard times, it is true, have brought the discussion home to every farmhouse and poor mans house in this town; but it is the chirping of grasshoppers beside the immortal question whether justice shall be done by the race of civilized to the race of savage man, whether all the attributes of reason, of civility, of justice, and even of mercy, shall be put off by the American people, and so vast an outrage upon the Cherokee Nation and upon human nature shall be consummated.

One circumstance lessens the reluctance with which I intrude at this time on your attention my conviction that the government ought to be admonished of a new historical fact, which the discussion of this question has disclosed, namely, that there exists in a great part of the Northern people a gloomy diffidence in the moral character of the government.

On the broaching of this question, a general expression of despondency, of disbelief that any good will accrue from a remonstrance on an act of fraud and robbery, appeared in those men to whom we naturally turn for aid and counsel. Will the American government steal? Will it lie? Will it kill? We ask triumphantly. Our counselors and old statesmen here say that ten years ago they would have staked their lives on the affirmation that the proposed Indian measures could not be executed; that the unanimous country would put them down. And now the steps of this crime follow each other so fast, at such fatally quick time, that the millions of virtuous citizens, whose agents the government are, have no place to interpose, and must shut their eyes until the last howl and wailing of these tormented villages and tribes shall afflict the ear of the world.

I will not hide from you, as an indication of the alarming distrust, that a letter addressed as mine is, and suggesting to the mind of the Executive the plain obligations of man, has a burlesque character in the apprehensions of some of my friends. I, sir, will not beforehand treat you with the contumely of this distrust. I will at least state to you this fact, and show you how plain and humane people, whose love would be honor, regard the policy of the government, and what injurious inferences they draw as to the minds of the governors. A man with your experience in affairs must have seen cause to appreciate the futility of opposition to the moral sentiment. However feeble the sufferer and however great the oppressor, it is in the nature of things that the blow should recoil upon the aggressor. For God is in the sentiment, and it cannot be withstood. The potentate and the people perish before it; but with it, and its executor, they are omnipotent.

I write thus, sir, to inform you of the state of mind these Indian tidings have awakened here, and to pray with one voice more that you, whose hands are strong with the delegated power of fifteen millions of men, will avert with that might the terrific injury which threatens the Cherokee tribe.

With great respect, sir, I am your fellow citizen,

Ralph Waldo Emerson

Certainly not “clean coal”, but is zero emission natural gas combustion a key to a zero Carbon future?

Eli Rabett has a great idea over at Rabett Run.

And I particularly like the directions which commentators Russell Seitz and John O’Neill are going with it. Hmmm, Dimethyl ether as a fuel?

It’s been proposed.

Key to Eli’s suggestion is the Chaudhary-Bhaskarwar paper, which I did not highlight sufficiently in the above.

Also, there already are patents declared in this space:

Per David B Benson, the original proposal by Eli is apparently something called the Allam power cycle, there is an update about it by its developer, and there is a project trying it nearing completion.

Will soils hang on to their Carbon?

This is essentially no analysis, simply an index to recent research on the the matter of the soils reservoir for Carbon, and a little reaction.

To begin, here’s the part of the Carbon Cycle that’s involved:

Should this production increase, particularly if CO2 uptake of terrestrial plants wane, the 45% sink we’ve fortunately lived with could lessen, making our situation worse.

Here are some papers, including reports of large scale experiments. I follow with some thoughts and questions.

I am particularly intrigued with Metcalfe, and van Groenigen, Osenberg, Luo, and Hungate. Recent studies examining options to rebalance the Carbon Cycle by means such as enhanced weathering and afforestation by planting large numbers of plants like Jatropha curcas (see more) have revealed the resulting albedo change and moisture capture can change the climate of entire regions. If microbial communities reorganize in a big way, whether in temperate forests, in deserts, or in tundra, could they by themselves achieve change of regional climate? Could they be bioengineered? Do we understand that ecosystem well enough to predict how it would develop? Are there nonlinear surprises lurking there?

“It should be illegal to deceive a country’s heart”

“I didn’t mean for this to happen.”

Intentions are irrelevant, despite what the law in one or more countries says.

Outcome and results are what matter.


As I wrote,

Oh, I am frustrated, because a lot of this discussion is pure deflection, nothing more.

Facts are, there are technologies available, which are difficult to defeat, and detectable if defeated, which can guarantee that the only user of a gun is the authorized owner of a gun. While I am not a gun owner, nor would I be, I understand that people want guns for hunting, whether game or humans (“in self defense”). Still, public safety and public health seem adequate justifications for imposing technological controls, backed up by legal measures for incriminating those who try to defeat those controls.

Guns should be available to those who want them, for legal purposes, but the rest of us should have the right to know who they are, and the authorities we assign with responsibility should have the right to intervene when public safety is threatened.

And the rest of the “self defense against tyranny” is nonsense, not supported by the Constitution, although one could cobble together some legal theory along those lines from circumstantial historical evidence, I admit.

Americans are not exceptional, no matter what they think. To the degree they do, quality of living here is worse than in the rest of the world, despite the audacious earnings per capita we so champion. Try to attract the Best And The Brightest in the world with that!

This is a completely artificially hepped and hyped and parochial issue, disconnected from reality. It is the worst shame the United States is capable of indulging, making everything in its history hypocrisy and a laughingstock. Securing the world against Nazism but allowing random empowered-with-guns nutcases to assault schools and churches, leaving surviving innocents with psychological trauma? What in the world are you defending if that’s what you want to allow?

I’ve offered my recommendations. Gun violence is a disease. It should be treated like any other disease.
