I stand with the trees and watch with the raptors.

Our friends at AWEO.org received a not untypically incoherent letter of complaint recently, which they haved shared with your editor. It came from Alabama, but I do not publish the author’s name, instead encouraging him to stop misdirecting his own energies, both negative and positive.
You could more effectively direct your energies to environmental and health consequences of millions of acres of oceans, atmosphere polluted by nuclear radiation and from fossil coal, and oil burning which is killing entire forests, poisoning sea life, and manifests health conseuqences for hundreds of millions if not billions of populations who can barely breathe in cities choked with pollution.

I stand with the trees and the raptors.

Your ignorance of the inetivable course of humanity in its greed for energy is an outrage. Complaining that governments waste money or that wind power engineering in its inefficiencies and pre-maturity or unsightlyness should be stopped in its tracks; pretending to prevent exploit of secondary 'renewable', in fact inexhaustible, solar wind and wave power would condemn centuries of windmills which have proven their utility and innocence for generations.

Soon the spectre of your poor ignorance will be redundant. Meso-scale changes in global weather perhaps even completely uncorrelated with the burning of dinosaurs and biomass which you prefer to ignore are forecast to endanger significant proportion of global populations living near seacoasts, and diminish those winds which, if properly exploited, might provide some glimmer of an alternative for the energy needs of billions on this planet.

Enjoy the weather.
AWEO replied as follows, and after several days have not received a reply in turn.
You claim to stand with the trees and the raptors, yet you would have the former leveled and the latter decimated to build enough wind towers to provide any meaningful fraction of our electricity needs — and only when the wind happens to be blowing in the right direction at the right speed, and never mind our other energy needs.

Obviously our efforts should be directed at cleaning up and reducing our actual energy use, not at pretending to provide alternatives that remain and ever will remain sideshows at best. But worse, they are sideshows increasingly destructive of landscape and wild habitat, as well as costly wastes of resources.

Conservation vs. Climate Change

As long as mitigating climate change trumps all other environmental concerns, no landscape on earth is safe. … Only an appreciation of nature as a collection of specific threatened habitats, rather than as an abstract thing that is “dying,” can avert the complete denaturing of the world.

By Jonathan Franzen, “The Other Cost of Climate Change”, The New Yorker, April 6, 2015

Last September, as someone who cares more about birds than the next man, I was following the story of the new stadium that the Twin Cities are building for their football Vikings. The stadium’s glass walls were expected to kill thousands of birds every year, and local bird-lovers had asked its sponsors to use a specially patterned glass to reduce collisions; the glass would have raised the stadium’s cost by one tenth of one per cent, and the sponsors had balked. Around the same time, the National Audubon Society issued a press release declaring climate change “the greatest threat” to American birds and warning that “nearly half ” of North America’s bird species were at risk of losing their habitats by 2080. Audubon’s announcement was credulously retransmitted by national and local media, including the Minneapolis Star Tribune, whose blogger on bird-related subjects, Jim Williams, drew the inevitable inference: Why argue about stadium glass when the real threat to birds was climate change? In comparison, Williams said, a few thousand bird deaths would be “nothing.”

I was in Santa Cruz, California, and already not in a good mood. The day I saw the Williams quote was the two hundred and fifty-fourth of a year in which, so far, sixteen had qualified as rainy. To the injury of a brutal drought came the daily insult of radio forecasters describing the weather as beautiful. It wasn’t that I didn’t share Williams’s anxiety about the future. What upset me was how a dire prophecy like Audubon’s could lead to indifference toward birds in the present.

Maybe it’s because I was raised as a Protestant and became an environmentalist, but I’ve long been struck by the spiritual kinship of environmentalism and New England Puritanism. Both belief systems are haunted by the feeling that simply to be human is to be guilty. In the case of environmentalism, the feeling is grounded in scientific fact. Whether it’s prehistoric North Americans hunting the mastodon to extinction, Maori wiping out the megafauna of New Zealand, or modern civilization deforesting the planet and emptying the oceans, human beings are universal killers of the natural world. And now climate change has given us an eschatology for reckoning with our guilt: coming soon, some hellishly overheated tomorrow, is Judgment Day. Unless we repent and mend our ways, we’ll all be sinners in the hands of an angry Earth.

I’m still susceptible to this sort of puritanism. Rarely do I board an airplane or drive to the grocery store without considering my carbon footprint and feeling guilty about it. But when I started watching birds, and worrying about their welfare, I became attracted to a countervailing strain of Christianity, inspired by St. Francis of Assisi’s example of loving what’s concrete and vulnerable and right in front of us. I gave my support to the focussed work of the American Bird Conservancy and local Audubon societies. Even the most ominously degraded landscape could make me happy if it had birds in it.

And so I came to feel miserably conflicted about climate change. I accepted its supremacy as the environmental issue of our time, but I felt bullied by its dominance. Not only did it make every grocery-store run a guilt trip; it made me feel selfish for caring more about birds in the present than about people in the future. What were the eagles and the condors killed by wind turbines compared with the impact of rising sea levels on poor nations? What were the endemic cloud-forest birds of the Andes compared with the atmospheric benefits of Andean hydroelectric projects?

A hundred years ago, the National Audubon Society was an activist organization, campaigning against wanton bird slaughter and the harvesting of herons for their feathers, but its spirit has since become gentler. In recent decades, it’s been better known for its holiday cards and its plush-toy cardinals and bluebirds, which sing when you squeeze them. When the organization shifted into Jonathan Edwards mode, last September, I wondered what was going on.

In rolling out its climate-change initiative, Audubon alluded to the “citizen science data” it had mobilized, and to a “report,” prepared by its own scientists, that justified its dire predictions. Visitors to its updated Web site were treated to images of climate-imperilled species, such as the bald eagle, and asked to “take the pledge” to help save them. The actions that Audubon suggested to pledge-takers were gentle stuff—tell your stories, create a bird-friendly yard—but the Web site also offered a “Climate Action Pledge,” which was long and detailed and included things like replacing your incandescent light bulbs with lower-wattage alternatives.

The climate-change report was not immediately available, but from the Web site’s graphics, which included range maps of various bird species, it was possible to deduce that the report’s method involved a comparison of a species’ present range with its predicted range in a climate-altered future. When there was broad overlap between the two ranges, it was assumed that the species would survive. When there was little or no overlap, it was assumed that the species would be caught between an old range that had grown inhospitable to it and a new range in which the habitat was wrong, and would be at risk of disappearing.

This kind of modelling can be useful, but it’s fraught with uncertainties. A species may currently breed in a habitat with a particular average temperature, but this doesn’t mean that it couldn’t tolerate a higher temperature, or that it couldn’t adapt to a slightly different habitat farther north, or that the more northerly habitat won’t change as temperatures rise. North American species in general, having contended with blazing July days and frosty September nights as they evolved, are much more tolerant of temperature fluctuations than tropical species are. Although, in any given place, some familiar back-yard birds may have disappeared by 2080, species from farther south are likely to have moved in to take their place. North America’s avifauna may well become more diverse.

The bald eagle was an especially odd choice of poster bird for Audubon’s initiative. The species nearly became extinct fifty years ago, before DDT was banned. The only reason we can worry about its future today is that the public—led by the then energetic Audubon—rallied around an immediate threat to it. The eagle’s plight was a primary impetus for the Endangered Species Act of 1973, and the eagle is one of the act’s great success stories. Once its eggs were no longer weakened by DDT, its population and range expanded so dramatically that it was removed from the endangered-species list in 2007. The eagle rebounded because it’s a resilient and resourceful bird, a generalist hunter and scavenger, capable of travelling large distances to colonize new territory. It’s hard to think of a species less liable to be trapped by geography. Even if global warming squeezes it entirely out of its current summer and winter ranges, the melting of ice in Alaska and Canada may actually result in a larger new range.

But climate change is seductive to organizations that want to be taken seriously. Besides being a ready-made meme, it’s usefully imponderable: while peer-reviewed scientific estimates put the annual American death toll of birds from collisions and from outdoor cats at more than three billion, no individual bird death can be definitively attributed to climate change (since local and short-term weather patterns have nonlinear causes). Although you could demonstrably save the lives of the birds now colliding with your windows or being killed by your cats, reducing your carbon footprint even to zero saves nothing. Declaring climate change bad for birds is therefore the opposite of controversial. To demand a ban on lead ammunition (lead poisoning is the foremost cause of California condor deaths) would alienate hunters. To take an aggressive stand against the overharvesting of horseshoe crabs (the real reason that the red knot, a shorebird, had to be put on the list of threatened U.S. species this winter) might embarrass the Obama Administration, whose director of the Fish and Wildlife Service, in announcing the listing, laid the blame for the red knot’s decline primarily on “climate change,” a politically more palatable culprit. Climate change is everyone’s fault—in other words, no one’s. We can all feel good about deploring it.

There’s no doubt that the coming century will be a tough one for wild animals. But, for countless species, including almost all of North America’s birds, the threat is not direct. The responses of birds to acute climatic stress are not well studied, but birds have been adapting to such stresses for tens of millions of years, and they’re surprising us all the time—emperor penguins relocating their breeding grounds as the Antarctic ice melts, tundra swans leaving the water and learning to glean grains from agricultural fields. Not every species will manage to adapt. But the larger and healthier and more diverse our bird populations are, the greater the chances that many species will survive, even thrive. To prevent extinctions in the future, it’s not enough to curb our carbon emissions. We also have to keep a whole lot of wild birds alive right now. We need to combat the extinctions that are threatened in the present, work to reduce the many hazards that are decimating North American bird populations, and invest in large-scale, intelligently conceived conservation efforts, particularly those designed to allow for climate change. These aren’t the only things that people who care about birds should be doing. But it only makes sense not to do them if the problem of global warming demands the full resources of every single nature-loving group.

A little tragicomedy of climate activism is its shifting of goalposts. Ten years ago, we were told that we had ten years to take the kind of drastic actions needed to prevent global temperatures from rising more than two degrees Celsius in this century. Today we hear, from some of the very same activists, that we still have ten years. In reality, our actions now would need to be even more drastic than they would have ten years ago, because further gigatons of carbon have accumulated in the atmosphere. At the rate we’re going, we’ll use up our entire emissions allowance for the century before we’re even halfway through it. Meanwhile, the actions that many governments now propose are less drastic than what they proposed ten years ago.

A book that does justice to the full tragedy and weird comedy of climate change is “Reason in a Dark Time,” by the philosopher Dale Jamieson. Ordinarily, I avoid books on the subject, but a friend recommended it to me last summer, and I was intrigued by its subtitle, “Why the Struggle Against Climate Change Failed—And What It Means for Our Future”; by the word “failed” in particular, the past tense of it. I started reading and couldn’t stop.

Jamieson, an observer and participant at climate conferences since the early nineties, begins with an overview of humanity’s response to the largest collective-action problem it has ever faced. In the twenty-three years since the Rio Earth Summit, at which hopes for a global agreement ran high, not only have carbon emissions not decreased; they’ve increased steeply. In Copenhagen, in 2009, President Obama was merely ratifying a fait accompli when he declined to commit the United States to binding targets for reductions. Unlike Bill Clinton, Obama was frank about how much action the American political system could deliver on climate change: none. Without the United States, which is the world’s second-largest emitter of greenhouse gases, a global agreement isn’t global, and other countries have little incentive to sign it. Basically, America has veto power, and we’ve exercised it again and again.

The reason the American political system can’t deliver action isn’t simply that fossil-fuel corporations sponsor denialists and buy elections, as many progressives suppose. Even for people who accept the fact of global warming, the problem can be framed in many different ways—a crisis in global governance, a market failure, a technological challenge, a matter of social justice, and so on—each of which argues for a different expensive solution. A problem like this (a “wicked problem” is the technical term) will frustrate almost any country, and particularly the United States, where government is designed to be both weak and responsive to its citizens. Unlike the progressives who see a democracy perverted by moneyed interests, Jamieson suggests that America’s inaction on climate change is the result of democracy. A good democracy, after all, acts in the interests of its citizens, and it’s precisely the citizens of the major carbon-emitting democracies who benefit from cheap gasoline and global trade, while the main costs of our polluting are borne by those who have no vote: poorer countries, future generations, other species. The American electorate, in other words, is rationally self-interested. According to a survey cited by Jamieson, more than sixty per cent of Americans believe that climate change will harm other species and future generations, while only thirty-two per cent believe that it will harm them personally.

Shouldn’t our responsibility to other people, both living and not yet born, compel us to take radical action on climate change? The problem here is that it makes no difference to the climate whether any individual, myself included, drives to work or rides a bike. The scale of greenhouse-gas emissions is so vast, the mechanisms by which these emissions affect the climate so nonlinear, and the effects so widely dispersed in time and space that no specific instance of harm could ever be traced back to my 0.0000001-per-cent contribution to emissions. I may abstractly fault myself for emitting way more than the global per-capita average. But if I calculate the average annual quota required to limit global warming to two degrees this century I find that simply maintaining a typical American single-family home exceeds it in two weeks. Absent any indication of direct harm, what makes intuitive moral sense is to live the life I was given, be a good citizen, be kind to the people near me, and conserve as well as I reasonably can.

Jamieson’s larger contention is that climate change is different in category from any other problem the world has ever faced. For one thing, it deeply confuses the human brain, which evolved to focus on the present, not the far future, and on readily perceivable movements, not slow and probabilistic developments. (When Jamieson notes that “against the background of a warming world, a winter that would not have been seen as anomalous in the past is viewed as unusually cold, thus as evidence that a warming is not occurring,” you don’t know whether to laugh or to cry for our brains.) The great hope of the Enlightenment—that human rationality would enable us to transcend our evolutionary limitations—has taken a beating from wars and genocides, but only now, on the problem of climate change, has it foundered altogether.

I’d expected to be depressed by “Reason in a Dark Time,” but I wasn’t. Part of what’s mesmerizing about climate change is its vastness across both space and time. Jamieson, by elucidating our past failures and casting doubt on whether we’ll ever do any better, situates it within a humanely scaled context. “We are constantly told that we stand at a unique moment in human history and that this is the last chance to make a difference,” he writes in his introduction. “But every point in human history is unique, and it is always the last chance to make some particular difference.”

This was the context in which the word “nothing,” applied to the difference that some Minnesotan bird-lovers were trying to make, so upset me. It’s not that we shouldn’t care whether global temperatures rise two degrees or four this century, or whether the oceans rise twenty inches or twenty feet; the differences matter immensely. Nor should we fault any promising effort, by foundations or N.G.O.s or governments, to mitigate global warming or adapt to it. The question is whether everyone who cares about the environment is obliged to make climate the overriding priority. Does it make any practical or moral sense, when the lives and the livelihoods of millions of people are at risk, to care about a few thousand warblers colliding with a stadium?

To answer the question, it’s important to acknowledge that drastic planetary overheating is a done deal. Even in the nations most threatened by flooding or drought, even in the countries most virtuously committed to alternative energy sources, no head of state has ever made a commitment to leaving any carbon in the ground. Without such a commitment, “alternative” merely means “additional”—postponement of human catastrophe, not prevention. The Earth as we now know it resembles a patient whose terminal cancer we can choose to treat either with disfiguring aggression or with palliation and sympathy. We can dam every river and blight every landscape with biofuel agriculture, solar farms, and wind turbines, to buy some extra years of moderated warming. Or we can settle for a shorter life of higher quality, protecting the areas where wild animals and plants are hanging on, at the cost of slightly hastening the human catastrophe. One advantage of the latter approach is that, if a miracle cure like fusion energy should come along, there might still be some intact ecosystems for it to save.

Choosing to preserve nature at potential human expense would be morally more unsettling if nature still had the upper hand. But we live in the Anthropocene now—in a world ever more of our own making. Near the end of Jamieson’s chapter on ethics, he poses the question of whether it’s a good thing or a bad thing that the arcadian Manhattan of 1630, lushly forested and teeming with fish and birds, became the modern Manhattan of the High Line and the Metropolitan Museum. People will give different answers. The point is that the change occurred and can’t be undone, as global warming can’t be undone. We were bequeathed a world of goods and bads by our forebears, and we’ll bequeath a world of different goods and bads to our descendants. We’ve always been not only universal despoilers but brilliant adapters; climate change is just the same old story writ larger. The only self-inflicted existential threat to our species is nuclear war.

The story that is genuinely new is that we’re causing mass extinctions. Not everyone cares about wild animals, but the people who consider them an irreplaceable, non-monetizable good have a positive ethical argument to make on their behalf. It’s the same argument that Rachel Carson made in “Silent Spring,” the book that ignited the modern environmental movement. Carson did warn of the dangers of pollution to human beings, but the moral center of her book was implicit in its title: Are we really O.K. with eliminating birds from the world? The dangers of carbon pollution today are far greater than those of DDT, and climate change may indeed be, as the National Audubon Society says, the foremost long-term threat to birds. But I already know that we can’t prevent global warming by changing our light bulbs. I still want to do something.

In “Annie Hall,” when the young Alvy Singer stopped doing his homework, his mother took him to a psychiatrist. It turned out that Alvy had read that the universe is expanding, which would surely lead to its breaking apart some day, and to him this was an argument for not doing his homework: “What’s the point?” Under the shadow of vast global problems and vast global remedies, smaller-scale actions on behalf of nature can seem similarly meaningless. But Alvy’s mother was having none of it. “You’re here in Brooklyn!” she said. “Brooklyn is not expanding!” It all depends on what we mean by meaning.

Climate change shares many attributes of the economic system that’s accelerating it. Like capitalism, it is transnational, unpredictably disruptive, self-compounding, and inescapable. It defies individual resistance, creates big winners and big losers, and tends toward global monoculture—the extinction of difference at the species level, a monoculture of agenda at the institutional level. It also meshes nicely with the tech industry, by fostering the idea that only tech, whether through the efficiencies of Uber or some masterstroke of geoengineering, can solve the problem of greenhouse-gas emissions. As a narrative, climate change is almost as simple as “Markets are efficient.” The story can be told in fewer than a hundred and forty characters: We’re taking carbon that used to be sequestered and putting it in the atmosphere, and unless we stop we’re fucked.

Conservation work, in contrast, is novelistic. No two places are alike, and no narrative is simple. When I travelled to Peru last November to see the work of a Peruvian-American partnership, the Amazon Conservation Association, my first stop was at a small indigenous community in the highlands east of Cuzco. With Amazon Conservation’s help, the community is reforesting Andean slopes, suppressing forest fires, and developing a business in a local legume called tarwi, which can thrive on degraded land and is popular enough in Cuzco to be profitable. In an old and dusty and dirt-floored building, women from the community served me a lunch of tarwi stew and dense, sweet tarwi bread. After lunch, in a neighboring courtyard, I toured a nursery of native tree saplings that the community will hand-plant on steep slopes, to fight erosion and improve local water quality. I then visited a nearby community that has pledged to leave its forested land intact and is operating an experimental organic farm. The scale of the farm is small, but to the community it means clear streams and self-sustenance, and to Amazon Conservation it represents a model for other communities. The regional and municipal governments have money from petroleum and mining royalties, and could spend it revitalizing the highlands according to the model. “We’re not jealous,” Amazon Conservation’s Peruvian director, Daniela Pogliani, told me. “If the government wants to take our ideas and take the credit, we have no problem with it.”

In an era of globalism of every sort, a good conservation project has to meet new criteria. The project has to be large, because biodiversity won’t survive in a habitat fragmented by palm-oil plantations or gas drilling. The project has to respect and accommodate the people already living in and around it. (Carbon emissions have rendered meaningless the ideal of a wilderness untouched by man; the new ideal is “wildness,” which is measured not by isolation from disturbance but by the diversity of organisms that can complete their life cycles.) And the project needs to be resilient with respect to climate change, either by virtue of its size or by incorporating altitudinal gradients or multiple microclimates.

The highlands are important to the Amazon because they’re a source of its water and because, as the planet heats up, lower-elevation species will shift their ranges upslope. The focal point for Amazon Conservation is Peru’s ManĂº National Park, a swath of lower-elevation rain forest larger than Connecticut. The park, which is home to indigenous groups that shun contact with the outside world, has full legal protection from encroachment, but illegal encroachment is endemic in the parks of tropical countries. What Amazon Conservation is attempting to do for ManĂº, besides expanding its upslope potential and protecting its watershed, is to strengthen the buffer on the flanks of the park, which are threatened by logging, slash-and-burn farming, and a boom in wildcat gold mining in the region of Madre de Dios. The project aspires to be a protective belt of small reserves, self-sustaining community lands, and larger conservation “concessions” on state-owned land.

On the fifty-five-mile road down from the highlands, it’s possible to see nearly six hundred species of bird. The road follows an ancient track once used to transport coca leaves from the lowlands to pre-Columbian highland civilizations. On trails near the road, Amazon Conservation researchers peaceably coexist with modern-day coca traffickers. The road bottoms out near Villa Carmen, a former hacienda that now has an educational center, a lodge for ecotourists, and an experimental farm where a substance called biochar is being tested. Biochar, which is manufactured by kiln-burning woody refuse and pulverizing the charred result, allows carbon to be sequestered in farm fields and is a low-cost way to enrich poor soil. It offers local farmers an alternative to slash-and-burn agriculture, wherein forest is destroyed for cropland, the soil is quickly exhausted, and more forest has to be destroyed. Even a wealthy country like Norway, seeking to offset its carbon emissions and to assuage its guilt, can’t save a rain forest simply by buying up land and putting a fence around it, because no fence is strong enough to resist social forces. The way to save a forest is to give the people who live in it alternatives to cutting it down.

At the indigenous village of Santa Rosa de Huacaria, near Villa Carmen, the community’s cacique, Don Alberto, gave me a tour of the fish farm and fish hatchery that Amazon Conservation has helped it develop. Large-scale fish farming is ecologically problematic in other parts of the world, but smaller-scale operations in the Amazon, using native fish species, are among the most sustainable and least destructive sources of animal protein. Huacaria’s operation provides meat for its thirty-nine families and surplus fish that it can sell for cash. Over lunch—farmed paco fire-roasted with yucca inside segments of bamboo, with heliconia-leaf plugs at each end—Don Alberto held forth movingly on the effects of climate change that he’d seen in his lifetime. The sun felt hotter now, he said. Some of his people had developed skin cancer, unheard of in the past, and the larvae of a palm-tree parasite, which the community had traditionally eaten to control diabetes and stimulate their immune systems, had vanished. Nevertheless, he was committed to the forest. Amazon Conservation is helping the community expand its land title and develop its own partnership with the national park. Don Alberto told me that a natural-medicine company had offered him a retainer and a jet in which to fly around the world and lecture on traditional healing, and that he’d turned it down.

The most striking thing about Amazon Conservation’s work is the smallness of its constituent parts. There are the eight female paco from which a season’s worth of eggs are taken, the humbleness of the plastic tanks in which the hatchlings live. There are the conical piles of dirt that highland women sit beside and fill short plastic tubes in which to plant tree seedlings. There are the simple wooden sheds that Amazon Conservation builds for indigenous Brazil-nut harvesters to shelter the nuts from rain, and that can make the difference between earning a living income and having to cut or leave the forest. And there is the method for taking a bird census in a lowland forest: you walk a hundred metres, stopping to look and listen, and then walk another hundred metres. At every turn, the smallness contrasts with the vastness of climate-change projects—the mammoth wind turbines, the horizon-reaching solar farms, the globe-encircling clouds of reflective particles that geoengineers envision. The difference in scale creates a difference in the kind of meaning that actions have for the people performing them. The meaning of climate-related actions, because they produce no discernible result, is necessarily eschatological; they refer to a Judgment Day we’re hoping to postpone. The mode of meaning of conservation in the Amazon is Franciscan: you’re helping something you love, something right in front of you, and you can see the results.

In much the way that developed nations, having long contributed disproportionately to carbon emissions, now expect developing nations to share the burden of reducing them, the rich but biotically poor countries of Europe and North America need tropical countries to do the work of safeguarding global biodiversity. Many of these countries are still recovering from colonialism, however, and have more urgent troubles. Very little of the deforestation of the Brazilian Amazon, for example, is being done by wealthy people. The deforesters are poor families displaced from more fecund regions where capital-intensive agribusinesses grow soybeans for Chinese tofu and eucalyptus pulp for American disposable diapers. The gold-mining boom in Madre de Dios is not only an ecological catastrophe but a human disaster, with widespread reports of mercury poisoning and human trafficking, but Peruvian state and federal governments have yet to put an end to it, because the miners make much better money than they could in the impoverished regions from which they’ve emigrated. Besides tailoring its work to the needs and capacities of local people, a group like Amazon Conservation has to negotiate an extremely complicated political landscape.

Wind energy saves 0.077% of California’s water

The trade lobby American Wind Energy Association has asserted that “wind energy saves 2.5 billion gallons of water annually in drought-parched California”, which is “around 65 gallons per person in the state (200 gallons per household)”. With the state now requiring households to reduce their water use by 25%, “wind energy’s water savings are therefore equivalent to what would be saved by nearly one week’s worth of the required reductions for a typical household”.

Nearly 1 week! That’s nearly 2%! Of household use — which represents only 4% of the total water use in California!

In short, wind energy theoretically (the displacement of water use by thermal plants is far from the simple one-for-one picture that AWEA implies) “saves” less than eight 100ths of one percent of California’s water.

[[[[ | ]]]]

The relatively small, albeit mostly unnecessary (almost all of it representing lawn watering), residential use not only illustrates the absurdity of AWEA’s boast, it also underscores the futility of the state’s emergency measures.

Here is the breakdown by sector of California’s water use in 2012, according to the Pacific Institute.


As one can see, besides the small amount used for lawn watering, there is another completely unnecessary use, but this one accounts for almost half of the total: meat and dairy: 47% of California’s water use.

What about almonds, it’s been hysterically asked?

Yes, among the plant crops, water use for almonds is highest, just above rice. And just above residential use in 2012. From 2012 to 2014, almond growing expanded by less than 5%. In other words, almonds are hardly the cause of the drought. It should also be noted that all nut crops (e.g., walnuts and pistachios, as well as almonds) use a lot of water. It’s because California grows more than 80% of the world’s almonds that the latter represents such a large proportion.


And again one sees the picture dominated by far by one culprit: the crops to feed meat and dairy animals: using almost 10 times as much water in California as almonds. As the Water Footprint Network has stated, “The water footprint of any animal product is larger than the water footprint of a wisely chosen crop product with equivalent nutritional value.”

The Lie of “100% Renewable”

It’s been recently reported that Georgetown “plans to be the first city in Texas entirely powered by renewable energy”. Of course, “plans to be” is a long way from “is”, but the first problem in most such reports is that they are talking only about electrical energy. Other energy consumption, such as for heating and transport, is not affected, so it is misleading indeed to say “entirely powered by renewable energy”.

Earlier this year, it was more accurately reported that the city of Burlington, Vermont, “became the first in the country to use 100 percent renewable energy for its residents’ electricity needs”. The news was further spread with far less care (and predictably) as, e.g., “the first city in the U.S. to be powered 100 percent by renewables”. Again, it is about electricity only, which is only about a third of our overall energy use. (Note should also be taken of the qualifier of “residents’ needs”: The University of Vermont, for example, is not included in this accounting.)

Even stated accurately, however, it remains misleading. Georgetown will be purchasing wind and solar power from faraway facilities. That means that they will in fact be using the same electricity on the grid as neighboring towns. The decision was strictly financial, not because wind and solar are cheaper, but because the country as a whole subsidizes them and the required new powerlines so that they can sell the power relatively cheaply. Furthermore, for Georgetown to find the price particularly attractive, as well as considering their non-ideological view, they will probably not be buying the Enron-invented “renewable energy credits”, i.e., they will not actually have the “right” to claim the purchase as “renewable”. (Instead, someone else, who also gets the same electricity from the grid as everyone else, will buy the RECs to claim the “green credit”.)

Sale of RECs also benefits Burlington, which sells them for its woodchip-fired plant and their ownership of wind plants in Georgia and Sheffield. Technically, they can therefore no longer claim that electricity themselves as “renewable”, although they account for almost two-thirds of the city’s electricity. As Burlington Electric itself shows, in 2013, ignoring their selling of RECs, 95% of their electricity was renewably sourced. After selling the RECs, that percentage dropped to 39%. And 67% of that was represented by the purchase of RECs.

Again, everything these cities do not generate themselves is taken from the regional grid, a pool of electrical energy that does not distinguish among its many sources. Georgetown will be using the same electricity as its “nonrenewable” neighbors. Burlington generates about half of its own electricity from wood chips, a little hydro, and negligible solar and wind. The rest is from the same pool as its “less renewable” neighbors.

And besides the charade of exclusive claims on renewable electricity that everyone shares equally on the grid, electricity is itself only about a third of their total energy use.

Meet climate targets by halving beef and lamb consumption

Rather than filling the world’s open spaces with giant wind turbines, paving them with solar panels (and access roads and substations and powerlines), and building 1000's of nuclear reactors, this article from The Telegraph notes that cutting beef and lamb consumption by half would more effectively reduce greenhouse gas emissions.

Cutting global beef consumption and eating chicken instead would do more to tackle climate change than building two million onshore wind turbines and 2,000 nuclear reactors, according to Government analysis.

Cows and sheep are so bad for the environment that switching just half the beef and lamb in an average diet to pork and poultry could enable the world to hit its global warming targets without using any nuclear plants or wind farms at all.

The figures are drawn from a new “global calculator” online tool, launched on Wednesday by the Department of Energy and Climate Change (DECC). ...

Most expert analyses show a vast expansion of low-carbon technologies including wind farms and nuclear plants to replace fossil fuels is likely to be needed to hit the targets.

However DECC’s calculator shows that other routes could technically be feasible – if people were prepared to change their behaviour. “Making changes in our lifestyle (for example our dietary and travel choices) can significantly reduce emissions and the effort needed across other sectors,” DECC said.

According to some estimates, beef production results in five times as many harmful emissions as equivalent chicken or pork production, while using 28 times as much land for grazing that might otherwise be used for forestry to help absorb carbon.

DECC works on the more conservative assumption that beef needs four times as much space as poultry, with an area the size of a football pitch used to produce 250 kg of beef or 1,000 kg of poultry.

It assumes that if the world carries on on current trends then by 2050 the global average diet – which is likely to mask huge variations between richer and poorer nations – would include 250g of red meat a week.

Replacing 100g of that with white meat could save 29 gigatonnes of carbon dioxide equivalent a year, it calculates.

The calculation assumes the world population will have grown to 10 billion by 2050, meaning the 100g-a-week switch saves one million tonnes of beef a week. As well as avoiding emissions from those cows, it would free up 1,400 million hectares of land for forests, which help absorb emissions. ...

By contrast, if every country in the world were to build wind farms at the fastest rate possible – increasing capacity to 6,470 gigawatts, or more than two million onshore wind turbines at current spec – that would save about 12 gigatonnes of emissions a year through replacing coal, gas and oil-burning power plants.

Building nuclear reactors at the fastest rate possible, increasing from 460 plants today to 2,340 plants in 2050, could save about 8 gigatonnes a year by 2050, the calculator suggests.

Are We Missing the Big Picture on Climate Change?

So Rebecca Solnit asks in today's New York Times Magazine, going on to show that she is indeed.

She begins by describing the remains of a bird scorched to death by the Ivanpah concentrated solar power facility, which has paved over a chunk of the desert "nearly five times the size of Central Park" (3,500 acres, to produce, according to Solnit, 392 megawatts of power at full capacity).

However, it can generate at that rate only when sun position and atmospheric conditions are ideal. The developers themselves project an average output of 30% capacity, or a total annual generation of just over 1,000,000 megawatt-hours. With an average household use of 10 megawatt-hours per year, that's equivalent to the electricity use of 100,000 households, not 140,000 as Solnit writes.

Therein lie her first manipulations of the story. Besides exaggerating the projected output of the Ivanpah facility and ignoring the fact that actual output has not been reported and is almost invariably much less than projected, as well as not considering the loss of at least 3,500 acres of desert habitat (new roads and transmission corridors were also built; desert tortoises were forcibly moved out), she uses the deceptive industry practice of expressing output in terms of "homes served". Domestic use of electricity represents only around 35% of the total. So in terms of total per-capita electricity use, the projected output of the Ivanpah facility would be equivalent to only the total amount used by the people from only 35,000 households.

And it would provide electricity for none at night. And electrical energy represents less than 40% of our total energy use. So the benefit in terms of reducing the use of other fuels becomes negligible. Considering the vast resources required to build the facility and the vast amount of land required to harness the energy, this hardly seems a wise path.

[Update:  In fact, the actual generation of electricity from the Ivanpah facility is reported to and by the Department of Energy. Those data can be daunting to sift through, but more than a month ago it was reported by Pete Danko at Breaking Energy that production was running well under 40% of what was projected (ie, less than 14,000 households, one tenth Solnit's claim), and that use of "auxiliary" natural gas had to be increased by 60%.]

Some waterfowl mistake that shining sea of mirrors for a real lake, so they try to land on it. But without water to launch themselves back into the air, they’re stranded, prey for coyotes or doomed to die of thirst or hunger. Other birds fly into Ivanpah, where, dazzled by glare, they collide with the mirrors or towers. Still others are scorched by the heat and fall to their deaths.

It’s this last form of avian death that became news. In August, The Atlantic described Ivanpah “incinerating” birds in flight; The Associated Press reported that wildlife investigators saw birds “ignite,” and that birds “burned and fell” every two minutes. Ivanpah’s corporate website noted that a death every two minutes would mean 100,000 dead birds a year, while only 321 dead and injured birds had been recovered. The actual number of deaths seems to be well above the power plant’s tally and far below the number reported by The Associated Press. But birds do die there, in many ways.

A second manipulation is in presenting the figure of "only 321" recovered bird corpses without context. Every such survey calculates an estimated "true" figure from such a sampling, considering imperfect recovery and loss to predators (such as the coyotes that Solnit mentions). In other words, Solnit's low figure, which she presents as final, is in fact only the starting point towards a much higher estimate.

But who cares, Solnit implies, because she's looking at the big picture. Let's not talk about what's actually happening at the Ivanpah facility, or whether the Ivanpah facility's benefits are enough to justify its harms, because climate change is a much bigger issue. And if you insist on worrying about the birds being killed there (or the displaced tortoises), you obviously don't care about climate change.
Supporters of fossil fuel and deniers of climate change love to trade in stories like the one about Ivanpah, individual tales that make renewable energy seem counterproductive, perverse. Stories cannot so readily capture the far larger avian death toll from coal, gas and nuclear power generation. Benjamin Sovacool, an energy-policy expert, looked into the deaths of birds at wind farms (where the blades can chop them down) and concluded that per gigawatt hour, nuclear power plants kill more than twice as many birds and fossil-fuel plants kill more than 30 times as many. He noted that over the course of a year fossil-fuel plants in the United States actually kill about 24 million birds, compared to 46,000 by wind farms. His calculations factor in climate change as part of their deadly impact.
That paragraph, typical of the logic of big energy apologists, is an absolute muddle. First, "individual tales" are precisely what make the climate change story compelling. So why write off these particular victims as something less? Yes, the toll from other sources of energy is much greater — that's because they represent a much greater proportion of our energy. Non-hydro renewable energy is still — and will likely always remain, because of its intermittency and variability — in the low single percentage points. And that's just electrical energy, which, recall, is less than 40% of total energy use.

So the question is not who kills more, but what can be done to kill less. Without meaningfully reducing our use of other fuels, giant wind and solar facilities are only adding to the toll, not reducing it.

Furthermore, the factoring of climate change in the calculation of bird deaths is the flip side of citing "only 321" bird corpses. It's meaningless. It's particularly questionable in the case of nuclear power, which does not emit carbon and so does not contribute to climate change (at least by that means).

Besides being manipulative, it is also simplistic, ignoring the fact that wind turbines, for example, are a particular danger to raptors (eagles, hawks, falcons, owls), whose populations (never mind the individuals!) are already challenged by habitat loss to humans. It ignores the toll on bats. And it ignores the huge increase of human land use (so much of it for supporting livestock, which represents massive deforestation, water depletion and pollution, and emissions of methane, which has 25 times the greenhouse effect of CO₂), ie, destruction of natural habitat, obviously the greatest barrier to plant and animal survival, resilience, and adaptation to climate change.
For a while our eyes were on the photographs of oil-soaked pelicans, victims of the 2010 BP blowout in the Gulf of Mexico. The devastation of the region is no longer news, but scientists, who track data for long unnewsworthy swathes of time, have found that the spill has killed more than 600,000 birds. It is still killing sea turtles and bottlenose dolphins and contaminating the seafood in areas where human beings fish. ... A recent Audubon Society report on climate change concludes: “Of the 588 North American bird species Audubon studied, more than half are likely to be in trouble. Our models indicate that 314 species will lose more than 50 percent of their current climatic range by 2080. Of the 314 species at risk from global warming, 126 of them are classified as climate endangered. These birds are projected to lose more than 50 percent of their current range by 2050.”
The latter part of the preceding excerpt points to the loss of habitat as being as much a problem as climate change. And the former part is relevant to oil use, but irrelevant to the toll at Ivanpah — because oil is used for transport and heating (and lubricating wind turbines and insulating their transformers), not for generating electricity. And again, these deaths are due to a catastrophic well blowout, not to climate change.
The technology for wind and solar farms can still be improved, but they are among the few remedies we have to the biggest problem humanity has ever faced. All over the world, renewable energy is proliferating — even on the plains of West Texas, there are now wind turbines among the fracking wells. Wind and solar are not only problems but solutions to the deadliness of the fossil fuel industry, whether it’s through routine devastation, as with tar sands, or catastrophic accidents, as with the BP spill, or the sabotage of the whole planetary system by climate change.
Having raising the unquestionable harms of an oil spill, now Solnit more directly contrasts it to wind and solar, even though, again, oil is not used for electricity. Even if wind and solar were everything their promoters claim (including the eternal canard that next year's technology and planning will solve all problems so don't worry about the continuing harm from last year's which if you think should be decommissioned you must really hate the planet), they would not change anything about oil at all. Insisting that wind and solar will save us almost seems a means of shrugging off the real problems of oil use, eg, that it is our use of it that drives all that drilling. Pave the desert with solar panels, string wind turbines across the mountain ridges: Just don't look, as Solnit's title suggests, at the big picture. Instead: Blame everything on climate change, and justify everything as fighting climate change.

She ends with a fire-and-brimstone vision of absolute calamity. She may not be wrong, but she would have us accept the deaths of birds and bats and the massive loss of habitat from building giant wind and solar projects as a distraction from the calamities due to climate change. That is exactly the self-rationalizing casuistry that guarantees — and justifies — only more calamity.

Update: 
  • “Before human populations swelled to the point at which we could denude whole forests and wipe out entire animal populations, extinction rates were at least ten times lower. And the future does not look any brighter. Climate change and the spread of invasive species (often facilitated by humans) will drive extinction rates only higher.” —Protect and serve, Nature 516, 144 (11 December 2014)
  • ‘Many species are already critically endangered and close to extinction, including the Sumatran elephant, Amur leopard and mountain gorilla. But also in danger of vanishing from the wild, it now appears, are animals that are currently rated as merely being endangered: bonobos, bluefin tuna and loggerhead turtles, for example.

    ‘In each case, the finger of blame points directly at human activities. The continuing spread of agriculture is destroying millions of hectares of wild habitats every year, leaving animals without homes, while the introduction of invasive species, often helped by humans, is also devastating native populations. At the same time, pollution and overfishing are destroying marine ecosystems.

    ‘“Habitat destruction, pollution or overfishing either kills off wild creatures and plants or leaves them badly weakened,” said Derek Tittensor, a marine ecologist at the World Conservation Monitoring Centre in Cambridge. “The trouble is that in coming decades, the additional threat of worsening climate change will become more and more pronounced and could then kill off these survivors.”’ —Earth faces sixth ‘great extinction’ with 41% of amphibians set to go the way of the dodo, The Observer, 14 December 2014
Update: Ando Arike writes:  ‘The climate-change angle we usually ignore is the apocalyptic side of the human “success story” — our phenomenal growth in population to seven billion from one billion in little more than two centuries. But our cleverness in transforming fossil-fuel energy into labor-saving technology and high-yield agriculture has gone to our heads. It’s not just the climate denialists who are anti-science; it’s also those renewable-energy optimists who ignore basic laws of thermodynamics and entertain the fantasy that it will be possible for seven billion to live in the style of the American middle class. The new story we need to tell is “managed degrowth” — gradually but significantly paring down our demands for resources and learning to live within the ecological budget of the earth.’

Evil masterminds behind citizen opposition to evil masterminds

Here’s a mildly fun game. The New York Times’ crusade against Russia has become such a caricature of cold-war-era propaganda that it now resembles the tirades against the Koch brothers for forcing all of us to burn fossil fuels like there’s no tomorrow and duping us into opposing the turning of our last rural and wild places into industrial wind and solar energy facilities.

On Nov. 30, the Times published an article by Andrew Higgins titled “Russian Money Suspected Behind Fracking Protests”. As with most such openly propagandistic pieces at the Times, the article is not opened to comments. The article is reminiscent of one at The Guardian on June 19 reporting then Nato chief Anders Fogh Rasmussen’s claim that Russia is “secretly working with environmentalists to oppose fracking”. Yes, the choice is between fracking (injecting a slew of toxic chemicals into the ground at high pressure to fracture rocks and release deposits of methane, much of which is released into the air, with some 25 times the greenhouse gas effect of CO₂) and ... what, exactly?

In each of these articles, one can simply substitute Russia with Exxon, Putin with the Koch Brothers, and fracking with wind turbines and, as if they were written from a “Mad Libs” template, one has another typical article that avoids the actual issue involved, rather evoking a vague powerful network of “astroturf” organizations surely backed by a nefarious puppetmaster. The articles flip the power relationship to portray the frackers/wind developers as victims of the monstrous power of local opposition. The local officials who thought it was fine to sell out their communities are left scratching their heads, cursing (and having it dutifully reported) what they can only assume (out of their own worldview) to be “well financed and well organized” opposition instead of acknowledging the power of democracy and information. The lack of evidence for the charges only proves how powerful the evil geniuses behind it really are. The fact that people across the social and political spectrum unite against these developments is also presented as proof that they can only be paid agents – or gullible dupes – instead of recognized, even celebrated, as the populist power of a common cause.

In the Guardian article, Greenpeace and Friends of the Earth laugh at Rasmussen’s claim. Maybe those groups should reconsider their own demonization campaigns against people who oppose large-scale wind and solar developments in rural and wild areas.

Renewable energy won’t reverse climate change

Ross Koningstein and David Fork, engineers at Google, write at IEEE Spectrum (excerpts):

At the start of RE<C, we had shared the attitude of many stalwart environmentalists: We felt that with steady improvements to today’s renewable energy technologies, our society could stave off catastrophic climate change. We now know that to be a false hope ...

As we reflected on the project, we came to the conclusion that even if Google and others had led the way toward a wholesale adoption of renewable energy, that switch would not have resulted in significant reductions of carbon dioxide emissions. Trying to combat climate change exclusively with today’s renewable energy technologies simply won’t work; we need a fundamentally different approach.

[T]oday’s renewable energy sources are limited by suitable geography and their own intermittent power production. Wind farms, for example, make economic sense only in parts of the country with strong and steady winds. The study also showed continued fossil fuel use in transportation, agriculture, and construction.

RE<C invested in large-scale renewable energy projects and investigated a wide range of innovative technologies .... By 2011, however, it was clear that RE<C would not be able to deliver a technology that could compete economically with coal, and Google officially ended the initiative and shut down the related internal R&D projects. ...

In the energy innovation study’s best-case scenario, rapid advances in renewable energy technology bring down carbon dioxide emissions significantly. Yet because CO₂ lingers in the atmosphere for more than a century, reducing emissions means only that less gas is being added to the existing problem. We decided to combine our energy innovation study’s best-case scenario results with Hansen’s climate model to see whether a 55 percent emission cut by 2050 would bring the world back below that 350-ppm threshold. Our calculations revealed otherwise. Even if every renewable energy technology advanced as quickly as imagined and they were all applied globally, atmospheric CO₂ levels wouldn’t just remain above 350 ppm; they would continue to rise exponentially due to continued fossil fuel use. So our best-case scenario, which was based on our most optimistic forecasts for renewable energy, would still result in severe climate change ...

Suppose for a moment that it had achieved the most extraordinary success possible, and that we had found cheap renewable energy technologies that could gradually replace all the world’s coal plants — a situation roughly equivalent to the energy innovation study’s best-case scenario. Even if that dream had come to pass, it still wouldn’t have solved climate change.

Incremental improvements to existing technologies aren’t enough; we need something truly disruptive to reverse climate change. What, then, is the energy technology that can meet the challenging cost targets? How will we remove CO₂ from the air? We don’t have the answers. Those technologies haven’t been invented yet.

[And then there's methane, with ~25 times the greenhouse gas equivalence of CO₂ and whose reduction would show effect in only a few years. Go vegan, people.]

Wind Turbines and Health: A Critical Review of a Critical Review of the Scientific Literature

J Occup Environ Med. 2014 Nov;56(11):e108-30. Robert J. McCunney, MD, MPH, Kenneth A. Mundt, PhD, W. David Colby, MD, Robert Dobie, MD, Kenneth Kaliski, BE, PE, and Mark Blais, PsyD

Objective: This review examines the literature related to health effects of wind turbines. Methods: We reviewed literature related to sound measurements near turbines, epidemiological and experimental studies, and factors associated with annoyance. Results: (1) Infrasound sound near wind turbines does not exceed audibility thresholds. (2) Epidemiological studies have shown associations between living near wind turbines and annoyance. (3) Infrasound and low-frequency sound do not present unique health risks. (4) Annoyance seems more strongly related to individual characteristics than noise from turbines. Discussion: Further areas of inquiry include enhanced noise characterization, analysis of predicted noise values contrasted with measured levels postinstallation, longitudinal assessments of health pre- and postinstallation, experimental studies in which subjects are “blinded” to the presence or absence of infrasound, and enhanced measurement techniques to evaluate annoyance.


Brief critique by Eric Rosenbloom:

“The Canadian Wind Energy Association (CanWEA) funded this project ....” McCunney and Colby had already prepared a similar review for the American and Canadian Wind Energy Associations (which are industry lobby groups) in 2009.

The paper consistently implies that the inaudibility of infrasound makes it nonproblematic, but by definition infrasound is inaudible and there is a substantial body of research showing that it is indeed harmful. The review ignores conference papers and so bypasses the issue of measurable infrasound inside homes as well as the unique characteristics of wind turbine noise as presented by many acousticians.

In its assessment of epidemiologic studies, the review rigorously critiques those that correlate wind turbine proximity and health problems while accepting without question those that find no such correlation (for example, a Polish study by industry consultants). In all cases that attempt to correlate complaints with noise levels, the latter are only estimated and characterized as continuous dBA tones. The paper picks out for special praise surveys that set out to prove “psychogenic” causes of health problems, which could not be more biased. This section concludes with a warning against the “mistaking of correlation with causation”, which only underscores the authors’ desperation to dismiss health problems as pre-existing and to ignore the consistent evidence that those health problems disappear when people move away or spend time away from the wind turbines (which they would no doubt only view as more evidence that they are indeed psychogenic, as if people willingly suffer physically in their homes but not when they are forced to abandon them). And again, they insist on the quotidian nature of wind turbine noise as being no different from ocean waves or air conditioning, ignoring the ever-growing documentation that it is indeed unique, and uniquely disturbing to many. As with other complaints, the review dismisses sleep disturbance as a fault of the sufferer, not the giant wind turbine thumping away all night. This bias is simply repeated in the next section that examines – and dismisses concerns about – infrasound and low-frequency noise. Again, the paper even denies that any infrasound and/or low-frequency noise (let alone that from wind turbines) can affect health, despite decades of research showing otherwise.

Continuing in this vein, the review of annoyance (a health effect according to the World Health Organization) examines only efforts to show it to be due only to the complainant’s psychology, not actual noise. The review unsurprisingly gives pride of place to the “nocebo” theory that nonsensically blames complaints on the publicity of them.

In its conclusion, the review cites the World Health Organization’s Night Noise Guidelines as a non sequitur vindication that wind turbine noise is not a problem, but fails to note that those guidelines specify an outside limit of 30 dB, which no jurisdiction on earth enforces, let alone regulation of amplitude modulation and infrasound, or even adequate setback distances, all of which the wind power industry fiercely fights (eg). The review itself makes no siting or regulatory recommendations (which might harm the industry paying for this review), instead placing the entire blame for problems on those who suffer them. A shameful performance.
