Anne Burns: The Virtual and the Visual in Ethnography (Medium)

Fox House, on the outskirts of Sheffield.

Feb 11, 2015

The ethnography I will be conducting for “Picturing the Social’ will be looking at practices of sharing photographs on social media. So is this to be a visual ethnography? A virtual ethnography? Or some kind of combination? Both of these approaches entail different theoretical and methodological models (Ardévol, 2012), which I will now briefly consider, along with outlining where this ethnography is situated in relation. Looking at these fields separately is not to suggest that they do not overlap — on the contrary, I believe that the visual and the virtual share many similarities. Photography is very much a social technology, in that images are typically created with the intention of sharing (Bourdieu, 1990), to the extent that photography has been termed the ‘original’ social media.

Virtual

The Internet can be used as a means for collecting data, or as the topic of research in itself (Markham and Baym, 2009). Much of the discussion of virtual ethnography considers this first function, in which the Internet is used to access participants. Studies of computer-mediated communication, on the other hand, focus on the specific features of online spaces, such as virtual worlds and games. This particular ethnography will be a combination of both, in that I am not using social media simply to find people to observe, but rather am interested specifically in their online practices. Therefore this is an ethnography of the virtual, rather than an ethnography which makes use of the virtual.

One of my areas of interest relates to the relationship between online and offline space, and the collapse of the division between the two. For example, how does the online construction of notions of Sheffield affect subjects’ experience of it offline? For some members of the social media groups I am considering, their predominant experience of Sheffield is now online, as they live elsewhere — how perhaps should this be conceptualised in regards to the online/offline divide? Additionally, not all online spaces are to be conceptualised alike, as the aims and objectives of virtual worlds, social networks and discussion forums are markedly different from one another. The photography groups I am looking to study as part of this ethnography are communities of interest, in which various motivations — including sharing memories, discussing contemporary issues and soliciting feedback on creative practice — must be explored and understood as affordances of these online spaces.

Internet ethnography offers a useful opportunity to participate in the same settings as participants, and to use the same tools for interactions and expression. This parity of access means that ethnography of online spaces is “meaningfully different” from the study of offline social practices (Kozinets, 2010: 5). Hine conceptualises this difference in terms of an emphasis on flow and connectivity, in contrast to ethnography’s prior focus on location and boundaries (2000). O’Reilly similarly states that virtual ethnography is challenging assumptions of what constitutes a ‘field site’, in that “instead of thinking in terms of places or locations, our Internet ethnographer looks to connections between things” (O’Reilly, 2009: 217). Pink also stresses the importance of considering connections and the “potential forms of relatedness” constituted online, in which online and offline materials and localities “become interwoven in everyday and research narratives” (Pink, 2012). I am particularly interested to explore how theories of place and space will be useful for this ethnography, in that the groups’ focus on Sheffield as a physical and conceptual place is mediated and constituted through online spaces. How do these different notions of place and space entangle, and how do they affect each other in order to create new notions of what constitutes Sheffield and people’s relationship to it? My early observations have already yielded an interesting example of the online representation of a sensory experience of Sheffield as locality and as history — a video uploaded to one Sheffield-themed social media group documents a walk through the post-industrial landscape, in which the participant draws attention to the shift from Sheffield’s identity as a steel working city, to a collection of vacant lots and empty office buildings. The online space is therefore used to provide not just a commentary on contemporary politics, but also to capture a physical experience, and an emotional reaction to it.

Visual

Ethnographies frequently use participant-generated photographs to explore the perspectives of those involved, enabling them to ‘speak’ through images (see Mitchell, 2011). As I am not inviting participants to produce materials for this project, but using those that they have made already, this approach is not applicable here. Although I will be considering people’s use of photography to discuss issues that are of relevance to them — relating to history, sport, wildlife, weather and so on — my aim is not to use photography to access those beliefs, but rather to explore the specific role of photographs in this process. Much as I stressed above regarding the virtual, this is not an ethnography that uses the visual, but is rather an ethnography of the visual.

I therefore similarly will not be using images within this ethnography in order to supplement my findings, or to ‘show’ something under the pretence of unmediated communication. This function, in which images act as a kind of supporting evidence, is problematic for numerous reasons, in that it assumes that images can be regarded as objective, but only fragmentary, adjuncts to text. As this ethnography is focused upon the practice and discussion of photography, such an approach to the visual would be inappropriate, as it fails to acknowledge that images must be studied as cultural objects in their own right. Therefore this ethnography of the visual will consider how images — at the level of objects as well as the production of objects — function within broader social relations (Pink, 2012: 5). As such, I will need to employ a range of theoretical approaches, which explore photography as a social process, as a form of identity negotiation, and as a phenomenon that continually remakes its own cultural circumstances of production.

Pauwels (2012) provides a particularly useful overview of conducting visual research, in which the status of the materials, and the extent to which they matter, is of primary concern. This is one of my main topics of investigation — not so much what images are of, but why they matter to people, what they enable viewers to do, say and think, and why they have been shared in the first place. For me, this is the key concern of contemporary visual research: what is it that makes social media photography — from the taking of snaps on Snapchat, to the sharing of photographs on Flickr — so important?

It will be my aim, therefore, to study how the visual and the virtual combine in the notion of ‘photographic sharing’. In particular, the social media communities in which these photographs are circulated will offer an important means for studying how notions of place are negotiated and constituted through the co-presence that is facilitated by looking at images online.

‘Picturing the Social: Transforming our Understanding of Images in Social Media and Big Data research’ is an 18-month research project that started in September 2014 and is based at the University of Sheffield in the United Kingdom. It is funded through an ESRC’s Transformative Research grant and is focused on transforming the social science research landscape by carving out a more central place for image research within the emerging fields of social media and Big Data research. The project aims to better understand the huge volumes of images that are now routinely shared on social media and what this means for society. This project involves an interdisciplinary team of seven researchers from four universities as well as industry with expertise in: Media and Communication Studies (Farida Vis and Anne Burns, University of Sheffield), Visual Culture (Simon Faulkner and Jim Aulich, Manchester School of Art), Software Studies and Sociology (Olga Goriunova, Warwick University), Computer and Information Science (Francesco D’Orazio, Pulsar and Mike Thelwall, University of Wolverhampton). The project is part of the Visual Social Media Lab.

Panel Urges Research on Geoengineering as a Tool Against Climate Change (New York Times)

With the planet facing potentially severe impacts from global warming in coming decades, a government-sponsored scientific panel on Tuesday called for more research on geoengineering — technologies to deliberately intervene in nature to counter climate change.

The panel said the research could include small-scale outdoor experiments, which many scientists say are necessary to better understand whether and how geoengineering would work.

Some environmental groups and others say that such projects could have unintended damaging effects, and could set society on an unstoppable path to full-scale deployment of the technologies.

But the National Academy of Sciences panel said that with proper governance, which it said needed to be developed, and other safeguards, such experiments should pose no significant risk.

In two widely anticipated reports, the panel — which was supported by NASA and other federal agencies, including what the reports described as the “U.S. intelligence community” — noted that drastically reducing emissions of carbon dioxide and other greenhouse gases was by far the best way to mitigate the effects of a warming planet.

But the panel, in making the case for more research into geoengineering, said, “It may be prudent to examine additional options for limiting the risks from climate change.”

“The committee felt that the need for information at this point outweighs the need for shoving this topic under the rug,” Marcia K. McNutt, chairwoman of the panel and the editor in chief of the journal Science, said at a news conference in Washington.

Geoengineering options generally fall into two categories: capturing and storing some of the carbon dioxide that has already been emitted so that the atmosphere traps less heat, or reflecting more sunlight away from the earth so there is less heat to start with. The panel issued separate reports on each.

The panel said that while the first option, called carbon dioxide removal, was relatively low risk, it was expensive, and that even if it was pursued on a planetwide scale, it would take many decades to have a significant impact on the climate. But the group said research was needed to develop efficient and effective methods to both remove the gas and store it so it remains out of the atmosphere indefinitely.

The second option, called solar radiation management, is far more controversial. Most discussions of the concept focus on the idea of dispersing sulfates or other chemicals high in the atmosphere, where they would reflect sunlight, in some ways mimicking the effect of a large volcanic eruption.

The process would be relatively inexpensive and should quickly lower temperatures, but it would have to be repeated indefinitely and would do nothing about another carbon dioxide-related problem: the acidification of oceans.

This approach might also have unintended effects on weather patterns around the world — bringing drought to once-fertile regions, for example. Or it might be used unilaterally as a weapon by governments or even extremely wealthy individuals.

Opponents of geoengineering have long argued that even conducting research on the subject presents a moral hazard that could distract society from the necessary task of reducing the emissions that are causing warming in the first place.

“A geoengineering ‘technofix’ would take us in the wrong direction,” Lisa Archer, food and technology program director of the environmental group Friends of the Earth, said in a statement. “Real climate justice requires dealing with root causes of climate change, not launching risky, unproven and unjust schemes.”

But the panel said that society had “reached a point where the severity of the potential risks from climate change appears to outweigh the potential risks from the moral hazard” of conducting research.

Ken Caldeira, a geoengineering researcher at the Carnegie Institution for Science and a member of the committee, said that while the panel felt that it was premature to deploy any sunlight-reflecting technologies today, “it’s worth knowing more about them,” including any problems that might make them unworkable.

“If there’s a real showstopper, we should know about it now,” Dr. Caldeira said, rather than discovering it later when society might be facing a climate emergency and desperate for a solution.

Dr. Caldeira is part of a small community of scientists who have researched solar radiation management concepts. Almost all of the research has been done on computers, simulating the effects of the technique on the climate. One attempt in Britain in 2011 to conduct an outdoor test of some of the engineering concepts provoked a public outcry. The experiment was eventually canceled.

David Keith, a researcher at Harvard University who reviewed the reports before they were released, said in an interview, “I think it’s terrific that they made a stronger call than I expected for research, including field research.” Along with other researchers, Dr. Keith has proposed a field experiment to test the effect of sulfate chemicals on atmospheric ozone.

Unlike some European countries, the United States has never had a separate geoengineering research program. Dr. Caldeira said establishing a separate program was unlikely, especially given the dysfunction in Congress. But he said that because many geoengineering research proposals might also help in general understanding of the climate, agencies that fund climate research might start to look favorably upon them.

Dr. Keith agreed, adding that he hoped the new reports would “break the logjam” and “give program managers the confidence they need to begin funding.”

At the news conference, Waleed Abdalati, a member of the panel and a professor at the University of Colorado, said that geoengineering research would have to be subject to governance that took into account not just the science, “but the human ramifications, as well.”

Dr. Abdalati said that, in general, the governance needed to precede the research. “A framework that addresses what kinds of activities would require governance is a necessary first step,” he said.

Raymond Pierrehumbert, a geophysicist at the University of Chicago and a member of the panel, said in an interview that while he thought that a research program that allowed outdoor experiments was potentially dangerous, “the report allows for enough flexibility in the process to follow that it could be decided that we shouldn’t have a program that goes beyond modeling.”

Above all, he said, “it’s really necessary to have some kind of discussion among broader stakeholders, including the public, to set guidelines for an allowable zone for experimentation.”

The Risks of Climate Engineering (New York Times)

THE Republican Party has long resisted action on climate change, but now that much of the electorate wants something done, it needs to find a way out of the hole it has dug for itself. A committee appointed by the National Research Council may just have handed the party a ladder.

In a two-volume report, the council is recommending that the federal government fund a research program into geoengineering as a response to a warming globe. The study could be a watershed moment because reports from the council, an arm of the National Academies that provides advice on science and technology, are often an impetus for new scientific research programs.

Sometimes known as “Plan B,” geoengineering covers a variety of technologies aimed at deliberate, large-scale intervention in the climate system to counter global warming.

Despairing at global foot-dragging, some climate scientists now believe that a turn to Plan B is inevitable. They see it as inscribed in the logic of the situation. The council’s study begins with the assertion that the “likelihood of eventually considering last-ditch efforts” to address climate destabilization grows every year.

The report is balanced in its assessment of the science. Yet by bringing geoengineering from the fringes of the climate debate into the mainstream, it legitimizes a dangerous approach.

Beneath the identifiable risks is not only a gut reaction to the hubris of it all — the idea that humans could set out to regulate the Earth system, perhaps in perpetuity — but also to what it says about where we are today. As the committee’s chairwoman, Marcia McNutt, told The Associated Press: The public should read this report “and say, ‘This is downright scary.’ And they should say, ‘If this is our Hail Mary, what a scary, scary place we are in.’ ”

Even scarier is the fact that, while most geoengineering boosters see these technologies as a means of buying time for the world to get its act together, others promote them as a substitute for cutting emissions. In 2008, Newt Gingrich, the former House speaker, later Republican presidential candidate and an early backer of geoengineering, said: “Instead of penalizing ordinary Americans, we would have an option to address global warming by rewarding scientific invention,” adding: “Bring on the American ingenuity.”

The report, considerably more cautious, describes geoengineering as one element of a “portfolio of responses” to climate change and examines the prospects of two approaches — removing carbon dioxide from the atmosphere, and enveloping the planet in a layer of sulfate particles to reduce the amount of solar radiation reaching the Earth’s surface.

At the same time, the council makes clear that there is “no substitute for dramatic reductions in the emissions” of greenhouse gases to slow global warming and acidifying oceans.

The lowest-risk strategies for removing carbon dioxide are “currently limited by cost and at present cannot achieve the desired result of removing climatically important amounts,” the report said. On the second approach, the council said that at present it was “opposed to climate-altering deployment” of technologies to reflect radiation back into space.

Still, the council called for research programs to fill the gaps in our knowledge on both approaches, evoking a belief that we can understand enough about how the Earth system operates in order to take control of it.

Expressing interest in geoengineering has been taboo for politicians worried about climate change for fear they would be accused of shirking their responsibility to cut carbon emissions. Yet in some congressional offices, interest in geoengineering is strong. And Congress isn’t the only place where there is interest. Russia in 2013 unsuccessfully sought to insert a pro-geoengineering statement into the latest report of the Intergovernmental Panel on Climate Change.

Early work on geoengineering has given rise to one of the strangest paradoxes in American politics: enthusiasm for geoengineering from some who have attacked the idea of human-caused global warming. The Heartland Institute, infamous for its billboard comparing those who support climate science to the Unabomber, Theodore J. Kaczynski, featured an article in one of its newsletters from 2007 describing geoengineering as a “practical, cost-effective global warming strategy.”

Some scholars associated with conservative think tanks like the Hoover Institution and the Hudson Institute have written optimistically about geoengineering.

Oil companies, too, have dipped their toes into the geoengineering waters with Shell, for instance, having funded research into a scheme to put lime into seawater so it absorbs more carbon dioxide.

With half of Republican voters favoring government action to tackle global warming, any Republican administration would be tempted by the technofix to beat all technofixes.

For some, instead of global warming’s being proof of human failure, engineering the climate would represent the triumph of human ingenuity. While climate change threatens to destabilize the system, geoengineering promises to protect it. If there is such a thing as a right-wing technology, geoengineering is it.

President Obama has been working assiduously to persuade the world that the United States is at last serious about Plan A — winding back its greenhouse gas emissions. The suspicions of much of the world would be reignited if the United States were the first major power to invest heavily in Plan B.

Aconselhado por espírito indígena, Pezão garante que choverá no Rio (Época)

Celebrai, povo fluminense: vem água por aí. Abram as torneiras, durmam no chuveiro e caprichem no banho do carro. Está liberado até encher a piscina de plástico azul das crianças. Basta comungar da mesma confiança que o governador do Rio, Luiz Fernando Pezão. Ele assegura à ÉPOCA, com tranquilidade budista, que racionamento e rodízio são palavras do passado. Cálculos de volume morto e obras na rede de águas são coisas de políticos sem fé. A convicção de Pezão é transcendental: vem dos céus – embora não de São Pedro. Choverá, ora, porque a médium Adelaide Scritori, a pedido de Pezão, consultou o espírito do Cacique Cobra Coral – e o Cacique mandou dizer que a água não tarda e chegará abundante. Quem é Pezão para discutir com o espírito do Cacique?

O último relato do Cacique veio por email – não do além, mas por meio de Adelaide. No documento, enviado no dia 28 de janeiro, garante-se  que “tudo o que faltou em dezembro e janeiro virá em fevereiro, março e abril”. O email, que afastou da cabeça do governador qualquer ideia de racionamento, foi repassado em seguida, como de costume, a Dilma Rousseff. “A presidente se diverte com os emails do cacique. Riu muito de um que afirmava que o culpado da crise hídrica e energética era o Lobão [Edison Lobão, ex-ministro de Minas e Energia]”, disse Pezão à ÉPOCA em seu gabinete, no Palácio Guanabara. Dilma riu, mas Pezão leva os conselhos do Cacique a sério.

A médium Adelaide lidera a Fundação Cacique Cobra Coral. Ela afirma incorporar o espírito do Cacique – um meteorologista sobrenatural, com capacidade para segurar uma tempestade aqui, mandar uma chuvinha lá e, graças a esse dom, fazer com que prefeituras e governos contratem a instituição para garantir seus serviços. No relatório que Pezão encaminhou a Dilma há, no entanto, um alerta para a possibilidade de temporais no Rio. Até junho, diz o Cacique, há o risco de chover, em apenas um dia, a quantidade esperada para um mês inteiro. “É preciso ficar alerta para o excesso de precipitação numa mesma localidade, como a zona norte”, avisa a entidade. Preparem a arca de Noé.

Pezão recebe com regularidade os informes que o espírito do Cacique envia à Prefeitura do Rio – o governo do Estado, afirma, não tem contrato com a fundação; a prefeitura, sim. Mas a relação de Pezão com o Cacique é antiga. Vem desde 1997, quando Pezão era prefeito de Piraí, município a 90 quilômetros da capital. “Eu sempre gostei de fazer festas na rua e conversava com eles para ter tempo bom. Chegava o dia da festa, chovia em todos os municípios vizinhos, e Piraí ficava sequinha, sequinha”, contou o governador. Com a prefeitura do Rio, os acordos da entidade mediúnica vêm dos tempos em que Cesar Maia era prefeito, no início de 2001. Eduardo Paes ameaçou romper com a fundação quando tomou posse em seu primeiro mandato, em 2009. Mas as previsões de temporais na noite do réveillon o fizeram rever a decisão. Não choveu e, desde então, além de satélites e outros instrumentos de alta tecnologia, o Rio conta com a expertise do cacique para ajudar nas previsões meteorológicas.

Mesmo sem contrato com o governo do Estado, a Fundação Cacique Cobra Coral parece estar se esforçando para garantir a normalização dos reservatórios. No domingo, dia 8, a médium Adelaide sofreu um acidente de carro na cidade de Paraibuna, em São Paulo. Ela vinha de Minas para o Rio de Janeiro, acompanhando o curso do rio Paraíba do Sul para avaliar, in loco, o nível dos reservatórios. O carro onde estava capotou três vezes e caiu no rio. Adelaide só teve escoriações leves. “Ela estava vendo tudo para informar ao cacique”, disse Pezão, que conecta seu celular para mostrar algumas fotos do acidente. Cair no rio não seria um mau sinal? “Não! Já está tudo certo, vai voltar a chover”, afirmou o confiante governador.

Das amplas janelas do gabinete de Pezão vê-se o jardim, espetacular, reformulado pelo paisagista francês Paul Villon no início do século XX. No meio do jardim, o chafariz de Netuno jorra, voluptuoso, litros e mais litros de água. “Mas é água de reuso”, apressa-se o governador a explicar, ao ouvir a pergunta sobre o desperdício –mesmo com toda a garantia dada pelo cacique de que o Rio está livre de problemas. Mas, pelo sim, pelo não, no dia seguinte o chafariz estava desligado.

Notes from the Anthropocene #1 (The Brooklyn Rail)

Nov 5th, 2014

On September 21, 2014, nearly 400,000 people took part in the People’s Climate March and Mobilization, winding their way from Central Park through Midtown Manhattan and ending with a block party celebration on the city’s mostly empty West Side (flooded during Sandy). Cleanly subdivided into six categories of political subjects—indigenous and environmental justice groups up front, a medieval combination of scientists and priests in the fifth, and finally “Here comes everybody! L.G.B.T.Q., N.Y.C. Boroughs, Community Groups, Neighborhoods, Cities, States, and more” in the sixth—the march called on the United Nations Climate Summit and governments around the world to steer a course towards appropriate “climate action” and “climate justice” on behalf of the groups neatly represented like meats and cheeses on a Hormel party tray. The following day, former anti-globalization and Occupy Wall Street activists, many on the payroll of this or that N.G.O., attempted a mass civil disobedience action on the blocks leading to the New York Stock Exchange. When the orchestrated non-violence of Flood Wall Street met the orchestrated non-brutality of the NYPD, ne’er an arrest occurred and the organizers called it all off, going home and turning the streets over to a few hundred unofficial protesters who were determined to be peacefully taken into custody.

As the United Nations met later that week to talk about talking about limiting global temperature rise to less than 3.6 degrees Fahrenheit (2 degrees Celsius) through a reduction in carbon emissions while simultaneously making economies, cities, and networks resilient, the People’s Climate Summit website released its own numbers: 400,000 people, 1,574 organizations, 50,000 college students, 5,200 articles, and 7 celebrity selfies. Homemade and mass-produced signs, puppets and inflatables, polar bear costumes and globes, thousands of buses whose bills were footed by non-profits and Gofundme.com, a pony-tailed Leo DiCaprio parading around as the U.N.’s Messenger for Peace, with a special focus on climate change issues. A success, they say, in launching the climate justice movement, a success as quantifiable as the parts per million of the upper safety limit for the atmosphere. As the march quickly faded into most New Yorkers’ memories, as when a million of us marched against the war that happened anyway, a variety of non-questions circulated to try to cement the march’s legacy. Was it too radical? Not radical enough? Too little too late? A photo-op? A corporate greenwash with the help of the “non-profit industrial complex”? 1 Non-questions for a non-world. Simply put, the Climate March was a blast from the past, mobilizing a set of political techniques and priorities that have literally been left behind by reality, by the new common in which we find ourselves.

A new epoch is certainly at hand; one need only trace the fault lines from the glacial barricades of Kiev’s Maidan across the radioactive swamp left by Fukushima’s failing ice wall to the “Winter is Coming” graffiti of Istanbul’s Gezi commune. Everywhere this age speaks its exhaustion, in the massive human efforts to break through and in the falling of idols. The once coherent subject around which the world was ordered stands in ruin as a neurotic information node whose closest relationship is with a cellphone or iPad. The claims to mastery over the world are being literally washed away by rising seas, while terminal diagnoses of our civilization proliferate as quickly as fantasies of the end (see the Walking Dead’s Terminus). As Brad Evans and Julien Reid describe it in their book Resilient Life, “We are living out the final scenes of the liberal nightmare in all its catastrophic permutations,” an epoch that is sensed just as much in the collapse of the Western Antarctic ice sheet2 and the bamboo barricades of Hong Kong as in the desertification of the Amazon rainforest and the death vows of the Lakota in the face of the KeystoneXL pipeline.3 Some people say the world is ending, but we say it is just a way of life, a certain order of things.

Ironically, it is geologists who have already arrived at this conclusion, by way of atmospheric chemist Paul Crutzen’s “launch[ing] a small hand grenade into the world of geological time scales.”4 Crutzen, formerly most famous for his Nobel Prize-winning research on the depletion of the ozone layer, used the term the Anthropocene in 2000 in a newsletter of the International Geosphere-Biosphere Programme.5 Since then geologists such as Jan Zalasiewicz have taken up the term, forming the Anthropocene Working Group (A.W.G.) to prepare a proposal for its inclusion in the International Commission on Stratigraphy’s official geological time scale. Etymologically the Anthropocene designates the “epoch of man”—a triumphal crowning of the liberal subject and its way of life, dated unsurprisingly from the middle of the 18th century. Stratigraphically the Anthropocene designates that Man has become the most powerful geological force on the planet, meaning that our measurable physical impact on sedimentation is more powerful than the oceans’ tides or the movement of mountains. Though in many popular accounts the Anthropocene is often reduced to the impacts of global warming or other processes contributing to climate change, geologists have focused on a series of metrics in addition to these such as deforestation, the acidification of the ocean, mass extinction, urbanization, the reshuffling of the biosphere, and the homogenization of environments. As such the perceptible triumph of man and his civilization, its coming to the fore as the most powerful force on earth, can best be measured in a catastrophic impact.

In light of the Anthropocene, geologists have also begun reshuffling their own rubrics, expanding the purview of paleontology from the organic to the inorganic and from the past to the present with the introduction of “technostratigraphy.”6According to Zalasiewicz and colleagues Colin Waters (Principal Mapping Geologist at the British Geological Survey) and Mark Williams (Professor of Palaeobiology with Zalasiewicz at Leicester), technofossils7 may well stand as the most convincing evidence of the epoch’s environmental signature. In the first-ever instance of geoscientists using anything other than biological fossils to help classify a chronostratigraphical unit, the A.W.G. are not looking at dinosaur vertebrae frozen in amber or ancient leaf imprints found in stone, but at critical infrastructures and cities like New York itself, which they see as “one of the most extensive, durable and geologically distinctive aspects of the Anthropocene” (Williams et al, 399) and thus as representative index fossils of the epoch’s recent, current, and near future. Whereas palaeontology has always been about studying past geological artifacts, the objects now under consideration as Anthropocene fossils—the key evidence in the Anthropocene dossier—are those of our present-day, still-functioning civilization. Thus for the first time in history, geologists are now dating an epoch in the present tense, studying contemporary, still functioning, infrastructures as fossils, studying the constituent elements of our civilization the way they once studied the remains of a long-vanished life form.

Through their attempt at naming and measuring the epoch of man, studying cities and subways as fossils in real time, and conjuring future geologists from outer space to study a world in which this civilization has completely vanished, thesegeologists have called our entire civilization and its requisite way of life a ruin. It would be easy to read the “humanity” implied in the Anthropocene as the final expression of modern man’s vanity, one last Promethean blast, but doing so misses entirely what’s most decisive about the stratigraphers’ concept: the Anthropocene elevates liberal humanity to prime geohistorical agent, center of the world, but does so only in the moment of its historical collapse. Has there ever been a civilization that named itself after its most cherished principle in order to call the whole thing a failure?

The Anthropocene as name and as phenomenon: the completion of the West, modernity, and liberal humanism. Seemingly by accident, coming from the sciences but immediately overflowing their bounds of acceptability—constant pressure to avoid seeming too negative and to remain dispassionate in their work—the geologists have cleared away the web of confusion. Naming the epoch after its first principle-in-ruins, they force us to face our age in all its schizophrenia.

Even if the geologists can’t quite say aloud what the New York Times could publish—“that this civilization is already dead”8—they place us succinctly and directly in the present. The end of the world is not this or that disaster coming in the future—a biblical flood, the next hurricane, the collapse of Midwestern agriculture—nor is it a potential future extinction of homo sapiens. The end of the world is what we are living through right now. And whereas the deluge of newspaper accounts of “the collapse of civilization”9 focus almost primarily on environmental factors, we insist that the devastation named by the Anthropocene is just as much a spiritual, existential, human devastation as it is an environmental one. It is impossible to separate the collapse of ice sheets from the collapse of man. Yet here again, in the very name itself, the Anthropocene seems to exceed what is considered polite or acceptable to say.

From this angle the People’s Climate March and Mobilization looks a bit different. Rather than being a matter of too much clicktivism, too few paint bombs, or of making demands to an utterly discredited institution, the Mobilization was designed to function as a last ditch attempt to shore up the present. At work in the generation of a discourse of climate crisis and a climate movement is an operation that dims down the complex reality of our epoch to a single phenomenon—global warming as generated by increased ppm of CO2—and deriving from that a set of clearly representable subjects—from “frontline communities” to “climate activists”—and a set of core questions—how can this situation be managed and how can this way of life be saved from itself?—that in effect attempt to hold back the apocalypse one more day, while also holding back any possibility of redemption. Keeping us cocooned, trapped, within an eternal, frozen present.

Conclusion

As Lauren Berlant writes, “the present is perceived, first, affectively: the present is what makes itself present to us before it becomes anything else” (Cruel Optimism, 4). This series will explore our present, an epoch for which we lack precedents or words but in which we are, already, called and shaped. Its aim is to read the tracks in front of us from within the situation, to recognize the present as it unfolds and to trace the breaths and rhythms with which it expresses itself. As such, the writing may occasionally take on different forms—stories, letters, interviews, or whatever seems appropriate. Future topics include “Those Who Go West” in Japan, extinction obsession, France’s Zone A Défendre and other ZADs, hacker spaces, autonomy, “survival skills,” and more. We will read the signs of the time and open ourselves up to the forms of life that are already coming to replace man in this exhausted age. An age obsessed with the end because it wants to see the world reborn.

A palavra dos cientistas sobre a crise da água (Fapesp)

ED. 227 | JANEIRO 2015

Estrategias a

A Academia Brasileira de Ciências (ABC) divulgou no dia 12 de dezembro a Carta de São Paulo, um documento com análises e recomendações para enfrentar a crise hídrica no Sudeste. Redigido sob a coordenação do pesquisador José Galizia Tundisi, do Instituto Internacional de Ecologia (IIE), o documento pede modificações imediatas na maneira de administrar os recursos hídricos. “É absolutamente necessário e imprescindível modernizar e dinamizar os sistemas de gestão”, afirmam os cientistas na carta. De acordo com os especialistas, há uma ameaça real à segurança hídrica do Sudeste, em especial na Região Metropolitana de São Paulo e no interior de Minas Gerais e do estado do Rio de Janeiro. O pano de fundo são indícios “fortíssimos” de mudança climática – que devem trazer eventos climáticos cada vez mais extremos – e o fato de os sistemas produtores de água não disporem de capacidade para garantir as vazões necessárias ao atendimento da demanda. Os cientistas recomendam uma drástica redução de consumo de água para 2015, investimentos imediatos em medidas de longo prazo e projetos de saneamento básico e tratamento de esgoto. Também defendem ações de divulgação e informação sobre as medidas emergenciais, os planos de longo prazo e a gravidade da crise. A íntegra da carta está disponível no site da ABC.

Água: crise e colapso em São Paulo (Revista Greenpeace)

Reportagem: Luciano Dantas

Edição 1, 2014

Desde o início do ano os moradores de São Paulo têm ido dormir sem saber se haverá água pela manhã em suas casas. Por meio de diferentes fontes, reunimos informações para levantar as causas, consequências e soluções para a crise hídrica que atinge o Estado.

Omissão e descaso: a falta d’água era prevista

Marussia Whately, coordenadora do Instituto Socioambiental (ISA) e uma das maiores especialistas em recursos hídricos de São Paulo, dá o seu diagnóstico. Assista:

“O uso do volume morto não é uma solução. Ele seca a represa, os lençóis freáticos e a capacidade do sistema em se recompor. Isso mostra a falta de preparo do governo do Estado para a crise.”

Marussia Whately

Dias difíceis

Desde maio deste ano a Sabesp se utiliza da água proveniente do chamado volume morto do Sistema Cantareira, principal manancial abastecedor da Grande São Paulo, para nutrir a capital.

“…Não há medida que consiga reverter esta situação em menos de cinco anos.”

Antonio Carlos Zuffo

Para o professor Antonio Carlos Zuffo, da área de Hidrologia e Gestão de Recursos Ambientais da Unicamp, o prognóstico é de dias difíceis. Segundo ele, além de enfrentar a escassez, os paulistas terão de lidar com a impureza da pouca água do reservatório. “Os peixes já vêm sofrendo com a falta de oxigênio dos rios e represas, e isso tende a piorar. Com um volume menor de água para a diluição de impurezas, a saída será o tratamento com maiores quantidades de cloro, o que compromete a qualidade da água que abastece residências, a produção agropecuária e industrial do Estado”, explica.

Zuffo acredita que a estiagem dure entre três e quatro décadas, e que a única saída para minimizar os prejuízos a curto-prazo é conscientizar a população. “A água economizada hoje será responsável pelo abastecimento de amanhã”, diz. E garante: não há medida que consiga reverter esta situação em menos de cinco anos.

A seca vira arte

Na contramão do que pensa a maioria dos moradores do Estado, Marcelo Delduque, morador de Bragança Paulista, não enxerga com tanta estranheza a seca que toma conta da represa que passa por sua propriedade, a Fazenda da Serrinha, já que a barragem foi construída artificialmente na década de 1970 para compor o Sistema Cantareira.

“Quando nasci, a represa não existia. Acompanhei durante a infância o povoado sendo alagado por ela. Por isso, para mim não é estranho ver tudo seco novamente”, conta.

É na centenária fazenda da família que há 13 anos acontece o Festival de Arte da Serrinha, produzido por Marcelo e seu irmão, Fábio Delduque, curador-responsável do evento. O festival propõe uma reocupação poética da paisagem rural por meio da arte contemporânea. É lá que artistas, estilistas, apaixonados e curiosos pela arte se embrenham, a cada ano, em produções artísticas livres e muito criativas.

Hoje a paisagem no entorno da fazenda é completamente diferente de quando a represa comportava seu nível normal de água. Assim, o que Marcelo pode acompanhar é o movimento contrário do qual vivenciou quando criança: o resgate das condições naturais do local, a retomada das raízes da Serrinha.

Curiosamente, o tema do Festival de 2014 foi justamente “Raízes”, e a paisagem do chão de barro rachado, que antes dava lugar à represa, tornou-se protagonista do evento.

    Falta de transparência: João exibe a quantidade de cloro contida na água após horas sem abastecimento. (Foto: acervo pessoal)

Morador do Mandaqui, zona norte da cidade de São Paulo, o estudante de jornalismo João Tiago Soares, 32, se queixa da falta de transparência praticada pela Sabesp. “Inacreditável. Até a Copa, tudo correu bem. Dias depois da final do campeonato, sem aviso prévio, o racionamento começou” – relata.

João afirma que no início faltava água por quatro horas durante a tarde e que depois foi faltando água cada vez mais tarde e por mais tempo. “Fechavam os reservatórios por volta das 22h, quando as pessoas se preparavam para dormir. Só abriam lá pelas 04h, quando estavam prestes a acordar”, conta. João diz que sempre que ele ou algum vizinho telefonam para a Sabesp, a resposta é a mesma: estão realizando uma “adequação” no sistema hídrico.

“Os recursos naturais de transformação da água em água potável são lentos, frágeis e muito limitados. Assim sendo, a água deve ser manipulada com racionalidade, precaução e parcimônia.”

Declaração Universal dos Direitos da Água

No último dia nove de setembro, Catarina de Albuquerque, relatora da ONU (Organização das Nações Unidas), declarou que a crise da água não pode ser justificada pela estiagem: cabe ao Estado prever e prevenir a população de circunstâncias como esta. Diante da crise, o recém-eleito governador Geraldo Alckmin continua negando a interrupção do abastecimento – praticada há pelo menos três meses – e descartou a necessidade de racionamento em 2014. Com mais quatro anos de mandato, veremos que medidas ele tomará para tirar a população do sufoco. Nem o cantor Chico Science seria capaz de prever lama e caos tão próximos um do outro.

Brazil drought: water rationing alone won’t save Sao Paulo (The Guardian)

The solutions to the severe drought in Brazil must go deeper than water rationing and pressure changes, says the Alliance for Water network

An aerial view of the Atibainha dam, part of the Cantareira reservoir, during a drought in Nazare Paulista, Sao Paulo state in this November 18, 2014.

It should be the rainy season. Instead Sao Paulo state is experiencing a third consecutive year with soaring temperatures and rainfall patterns well below historic records.

The main water reservoirs are operating at their lowest capacity. The Cantareira reservoir system, which serves more than nine million people in the state, is only 5% full. At the Alto Tietê reservoir network, which supplies three million people in greater Sao Paulo, water levels are below 15%.

Simple calculations indicate that given the current level of consumption versus the predicted raining patterns there is only enough water on the system to last four to six months. That means the water could run out before the next rainy season starts in November. State officials recently announced a potential rationing program of five days without water and two days with, in case the February and March rains do not refill the reservoirs.

This extreme climate scenario, combined with a series of management flaws, political negligence and a culture of waste and pollution, is bringing the largest metropolitan region of Brazil to the brink of collapse.

Since 2013, after decades of warnings about misguided development policies and destructive land use practices, experts and civil society organisations have been calling for increasingly strong measures to reduce water consumption to keep the minimum secure levels for supply reservoirs. The calls have been ignored by the state government – the system’s main operator – and federal and municipal authorities turned a blind eye to the severity of the situation.

The government took a few small steps in early 2014, such as offering a discount on water bills for people who voluntarily reduced their consumption. It also increased supply from the Billings and Guarapiranga reservoirs, but as these sources receive most of the urban waste from Sao Paulo, the water needs to be carefully tested and treated to be adequate for human consumption, adding to the complexity of securing safe water supply during the drought.

The government’s main initiative has been to reduce pressure on the distribution network, so that it pumps less water through the system. As the measure was not officially recognised by leaders or the media, people were unprepared to live without drinkable water for a couple of days when the supply glitches started to happen. Taken by the population as a de facto rationing, the lack of transparency about the times and places affected by pressure reduction caused more problems and increased distrust among Sao Paulo’s citizens.

The recovery measures adopted so far account for a 22% reduction on the water volume extracted from reservoirs. Experts, however, advise that the reduction should be around 50% to sustain the minimal conditions needed for the system.

Many might be surprised that such a scenario is happening in a tropical country famous for its abundance of natural resources, crossed by hundreds of rivers and with plenty of underground water. But for regional environmentalists and experts it comes as no surprise. They have been raising the alarm on water pollution and campaigning for watershed protection and safety standards since the 1980s. But scientific and technical reports, advocacy measures and pressures on companies were lost among the apparently unstoppable powers of real estate, agriculture and industry development. Urban land use, extensive monocultures and illegal occupation of watersheds have damaged and polluted the water production areas, jeopardising their capacity to survive and recover from extended dry seasons.

National development policies strongly focus on macro-infrastructure plans such as large hydrodams, ports and roads, the expansion of agribusiness into the Amazon, and the predatory mining industry. These sustain the exports of soya, beef and pig iron while being responsible for the majority of Brazilian greenhouse gas emissions. More and more scientific studies show the link between deforestation in the north and the reduction of rainfall in the southeast, presenting further evidence of how the effects of climate change are already upon us.

Despite the relative gains in poverty reduction over the last decade, the imminent collapse of the water supply system of the richest region in Brazil shows that basic development structures have yet to be addressed and fundamental human rights have yet to be secured in this country. Millions of people from the poorest communities have entered the consumer market, but their access to housing, sanitation, clean water, citizen security and transport remain unguarded.

This is where an old cliché becomes real: major opportunities lie within this crisis. The transcending effect of the water shortage creates a space for unity and coordination among Brazilian social movements. It offers the chance for environmental organisations to link deforestation with urban issues, to communicate that social justice will not be achieved as long as the priority is given to an unequal and unsustainable development model. Moreover, the urgency and scale of the water crisis is likely to bring NGOs and labour unions closer to the organic and youth protests that drew hundreds of thousands of people to the streets in 2013. The time and place for a solid narrative that links poverty reduction to ecological protection seems finally to have arrived.

In October 2014, more than 40 NGOs, experts, independent collectives and social movements joined forces to launch the Alliance for Water, a network that is monitoring the government’s response to the crisis and presenting positive solutions for surviving the probable collapse. The alliance aims to collaborate to build a new culture of water use and conservation in Sao Paulo and is producing a series of technical reports and events to qualify the debate among a wide range stakeholders, from specialists to politicians to social movements and grassroots groups.

Today more than 13 million inhabitants of Sao Paulo state find themselves on the edge of an unprecedented public calamity. The absence of political leadership and government transparency fuels panic and fear. Until now, the government has not outlined a clear emergency plan to guarantee minimum water supplies for essential services such as hospitals, police stations and prisons, and for the poorest people who have no structure to store or buy mineral water. A chaotic scenario might take place where, faced with a severe and sustained lack of water, many communities will resort to polluted sources or even violence, raising significant concerns over safety and health.

Civil society has a pivotal role to play by challenging development models, establishing social control over emergency plans, securing human rights and promoting the values of ethics and solidarity. As is usual in calamity situations, the most vulnerable, poorest communities are likely to pay the highest price with their health and their dignity. These people need to know they can count on organised civil society to support them across the turbulent times that lie ahead.

IPCC: climate denial, fundamental restructuring of global economy and social structures, and vested interests and climate governance

IPCC AR5, WG III, Chapter 4

Sent by Robert J. Brulle

Climate Denial – pages 300 – 301 

Denial mechanisms that overrate the costs of changing lifestyles, blame others, and that cast doubt on the effectiveness of individual action or the soundness of scientific knowledge are well documented (Stoll-Kleemann et  al., 2001; Norgaard, 2011; McCright and Dunlap, 2011), as is the concerted effort by opponents of climate action to seed and amplify those doubts (Jacques et  al., 2008; Kolmes, 2011; Conway and Oreskes, 2011).

Fundamental restructuring of global economy and social structure – page 297

Third, effective response to climate change may require a fundamental restructuring of the global economic and social systems, which in turn would involve overcoming multiple vested interests and the inertia associated with behavioural patterns and crafting new institutions that promote sustainability (Meadows et  al., 2004; Millennium Ecosystem Assessment, 2005)

Vested Interests and Climate Governance – page 298

A defining image of the climate governance landscape is that key actors have vastly disproportionate capacities and resources, including the political, financial, and cognitive resources that are necessary to steer the behaviour of the collective within and across territorial boundaries (Dingwerth and Pattberg, 2009). A central element of governance therefore relates to huge asymmetry in such resources and the ability to exercise power or influence outcomes. Some actors, including governments, make use of negotiation power and/or lobbying activities to influence policy decisions at multiple scales and, by doing so, affect the design and the subsequent allocation and distribution of benefits and costs resulting from such decisions (Markussen and Svendsen, 2005; Benvenisti and Downs, 2007; Schäfer, 2009; Sandler, 2010) — see e.g., Section 15.5.2. The problem, however, also resides in the fact that those that wield the greatest power either consider it  against their interest to facilitate rapid progress towards a global low carbon economy or insist that the accepted solutions must be aligned to increase their power and material gains (Sæverud and Skjærseth, 2007; Giddens, 2009; Hulme, 2009; Lohmann, 2009, 2010; Okereke and McDaniels, 2012; Wittneben et  al., 2012). The most notable effect of this is that despite some exceptions, the prevailing organization of the global economy, which confers significant power on actors associated with fossil fuel interests and with the financial sector, has provided the context for the sorts of governance practices of climate change that have dominated to date (Newell and Paterson, 2010).

SP, MG e Rio: 87% atribuem crise hídrica aos governantes, diz pesquisa (O Globo)

Na Grande São Paulo, segundo a consultoria Expertise, 92,5% colocam na conta do governo o problema

POR LEONARDO GUANDELINE

11/02/2015 6:00 / ATUALIZADO 11/02/2015 12:23

SÃO PAULO – Aumentou entre paulistas, cariocas e mineiros o número de pessoas que atribuem a responsabilidade pela atual crise hídrica ao governo (municipal, estadual e federal). É o que mostra pesquisa inédita sobre o tema realizada via internet pela consultoria mineira Expertise. Num primeiro levantamento, feito em outubro passado, 75% dos entrevistados colocavam a crise na conta dos governantes. Em fevereiro deste ano, esse número subiu para 87%. Na Grande São Paulo, região que enfrenta problemas no abastecimento de água há mais de um ano, 92,5% dos entrevistados acreditam que os governantes têm muita responsabilidade pela crise – eram 78% na pesquisa anterior.

Dos 2.138 entrevistados em São Paulo (interior e região metropolitana da capital), Minas (interior e Grande Belo Horizonte) e Rio, 75% responsabilizam a população (ante 78% da pesquisa anterior) pela crise e 74% as empresas responsáveis pelo abastecimento (eram 62% no levantamento anterior) pelo problema.

Em outubro, os entrevistados diziam que o principal fator que levou à crise foi o mau uso da água e dos recursos naturais pela população (o item agora ocupa a segunda posição, segundo 21% dos entrevistados). Na pesquisa atual, a falta de planejamento dos governantes (na opinião de 29% dos internautas), que ficava em terceiro lugar, lidera. Segunda posição no levantamento de outubro, a falta de chuva hoje ocupa o quinto lugar, segundo 13% dos entrevistados.

Segundo a pesquisa, 48% dos internautas disseram ter tido pelo menos um corte de água nos últimos dias. Na região metropolitana da capital paulista, esse número sobe para 70%.

À consultoria Expertise, 91% dos entrevistados acham que o governo poderia ter evitado que a crise chegasse a tal ponto. Outros 89% acreditam que a crise hídrica vai afetar o fornecimento de energia. Dos internautas, 87% demonstram estar “bem preocupados” com a falta d’água.

Para 66%, a tendência é de piora no quadro nos próximos 12 meses. E 90% disseram acreditar que o preço da água vai subir.

A Expertise realizou as entrevistas online em janeiro e fevereiro deste ano, com homens e mulheres de todas as classes sociais. A margem de erro da pesquisa é de 2,1 pontos percentuais, para mais ou para menos.

AUMENTO NO ESTOQUE DE ÁGUA

Se em outubro o número de entrevistados ouvidos pela consultoria que disseram estar estocando ou pensando em estocar água era de 64%, em fevereiro esse percentual subiu para 73%.

À consultoria Expertise, os entrevistados ainda responderam sobre uma série de mudanças no comportamento. 83% disseram ter diminuído o tempo no banho e 72% passaram a fechar a torneira ao escovar os dentes ou lavar a louça. Dos internautas, 60% contaram que estão, de alguma forma, reutilizando água e 57% passaram a lavar menos roupa.

Os favoráveis ao racionamento somam 73% ante 77% do levantamento feito pela consultoria em outubro.

Senado pode ter comissão externa para acompanhar falta d’água no Sudeste (Agência Senado)

Se a comissão temporária for mesmo criada, o trabalho será feito em parceria com a Agência Nacional de Águas

O senador Jorge Viana (PT-AC) anunciou nesta terça-feira (10) que vai propor a criação de uma comissão temporária do Senado para acompanhar a precariedade no abastecimento de água aos habitantes da Região Sudeste. Para Viana, há uma soma de duas situações: uma seca sem precedentes e a ocupação desordenada do solo, com a destruição de nascentes.

— Toda a floresta protetora ao longo de riachos e rios nessa região foi danificada. Não restaram mais de 6% da Mata Atlântica. Eu entendo que é como se o Brasil estivesse buscando essa situação há muitas décadas, afirmou.

Jorge Viana acentuou que a falta d’água atinge mais de 50 milhões de pessoas. Corresponde, segundo ele, a um quarto da população nacional e afeta 70% do produto interno bruto (PIB). Nesta terça, o sistema Cantareira, que abastece quase toda a capital paulista, operava com 6,1% da capacidade.

Se a comissão temporária for mesmo criada, o trabalho será feito, conforme explicou Jorge Viana, em parceria com a Agência Nacional de Águas (ANA) e com o Centro de Monitoramento de Cachoeira Paulista.

— Espírito Santo, Rio de Janeiro, São Paulo e Minas Gerais estão passando por um gravíssimo problema. Eu, como engenheiro florestal e como senador da Amazônia e do Acre, quero dar minha contribuição me aprofundando nesse tema. É preciso por o dedo nessa ferida de ausência de investimentos e de políticas públicas adequadas — concluiu o senador.

Veneza Paulista privatiza rio e oferece alívio à crise hídrica (Conta D’água)

por Laura Capriglione, da Ponte com fotos de Mídia NINJA

11 de fevereiro de 2015

Enquanto a capital paulista enfrenta rodízio e falta d’água, condomínio no interior desvia curso de rio para criar clima veneziano. Moradores passeiam entre as casas de pedalinho.

Você anda chateado com a perspectiva de viver o tal do rodízio de cinco dias a seco para apenas dois com água? Anda procurando, sôfrego, tutoriais no Youtube sobre como construir sua cisterna caseira? Na geladeira da sua casa, ao lado dos tradicionais ímãs com os telefones da pizzaria, da lavanderia e do petshop, agora já tem um de caminhão-pipa? Seus dias de angústia acabaram!

Bem pertinho, a 70 km de São Paulo, você poderá se tornar o feliz proprietário de uma casa com água à vontade — água até dizer chega. Na verdade, trata-se de um rio inteiro, desviado de seu curso normal só para o bem-estar e lazer dos moradores. E tudo com a segurança de um condomínio fechado, vigiado 24 horas por dia por câmeras de monitoramento.

Cenas bucólicas da Veneza Paulista. Pedalinhos e pontes marcam o cenário das ilhas artificiais. Fotos: Mídia NINJA

Trata-se do Condomínio Ribeirão do Vale, situado em Bom Jesus dos Perdõesna beira da rodovia Dom Pedro I. Ali, 200 casas, 95% das quais equipadas com piscinas, desfrutam o privilégio de ter um rio de águas límpidas passando pelo quintal. Moradores usam pedalinhos –sim, pedalinhos! — para visitar os vizinhos. Pontes românticas ligam os quarteirões ilhados.

Que lindo!

E pensar que, enquanto uns se viram com pedalinhos, piscinas e um rio para chamar de seu, quase no centro de São Paulo milhares de pessoas se veem completamente à mercê dos caprichos da Sabesp, ligando e desligando a água quando lhe dá na telha.

As quinhentas famílias e mais de 2.000 moradores empilhados em barracos tentando preservar alguma dignidade diante das precárias condições de saneamento e superpovoamento do local…

Noventa por cento das casas não têm caixa d’água e, portanto, quando a torneira fica seca é a vida que seca.

Quem ali tem dinheiro para comprar água mineral ou contratar caminhão-pipa a R$ 1.200 a carga de 15.000 litros?

A ironia cruel é que também a favela da Vila Mariana convive diariamente com um rio, no caso o córrego do Sapateiro, que foi aterrado e passa bem embaixo do chão. Em alguns barracos ainda dá para ouvir o som da água subterrânea correndo. Mas fica nisso.

Diariamente, os moradores da favela Mario Cardim se apressam em fazer as atividades domésticas de lavar roupas e panelas, ao mesmo tempo em que põem a comida no fogo. Tudo muito rápido, antes que a torneira seque novamente.

Mas não pensemos nisso. E voltemos rapidamente para o Condomínio Ribeirão do Vale, injustamente apelidado de Veneza Paulista. É injusto porque o condomínio tem vantagens notáveis sobre o original vêneto/italiano. Por exemplo, moradores da versão brasileira podem pescar em seus quintais peixes nativos, como tilápias, pacus, curimbatás, bagres. Também se encontram ali espécies alienígenas, como os matrinxãs, que foram trazidos da bacia amazônica especialmente para o local.

Veneza perde!

Os repórteres da Conta D’Água visitaram o condomínio para ver como funciona esse paraíso. Entraram na área privada a pretexto de comprar um imóvel. Havia dois, anunciados pela internet.

Logo no primeiro, depararam-se com o morador na casa vizinha, senhor Luís, que explicou: o condomínio mantém três moinhos em funcionamento permanente a fim de oxigenar a água e manter os peixes saudáveis por mais tempo.

Pescador sortudo, ele se vangloriava da peixada de curimbatá na brasa que fizera na véspera. “Aqui é um oásis no meio da seca”.

O oásis, no caso, custa caro: R$ 330.000, que é o preço de um imóvel assim anunciado: “4 dormitórios, 3 wc, sala, cozinha, varanda com churrasqueira, piscina, rio com pedalinho”.

A ducha de água fria, contudo, o próprio corretor encarregou-se de jogar nos ansiosos compradores que éramos nós. É que as casas do local não têm escritura definitiva. Mas apenas uma tal “escritura de direitos possessórios”. Ou seja, R$ 330.000 a menos no bolso, o comprador será apenas um “posseiro”, sem direito a registro definitivo do imóvel.

Mas, o corretor avisa, “não tem perigo, não”. “O próprio ex-prefeito de Bom Jesus dos Perdões, Calé Riginik, do PSDB, é o morador até hoje da casa 10 do condomínio. Você acha que o ex-prefeito compraria um imóvel aqui se houvesse o mínimo risco de perdê-lo?” Imagine o leitor se em vez do prefeito e de gente como nós, fingindo ter R$ 330.000, “cash”, se não haveria risco de uma violenta “ação de reintegração de posse”, como aconteceu no tristemente famoso caso Pinheirinho.

Em uma entrevista ao jornal “Folha de S.Paulo” realizada em 2010, o então secretário de obras de Bom Jesus dos Perdões, Gerson Coli, admitiu que o condomínio foi instalado sobre o leito do ribeirão Cachoeirinha, “sem licenças dos órgãos devidos (como a Cetesb)”.

No dia 4 de novembro de 2011, entretanto, veio a redenção diretamente do Departamento de Águas e Energia Elétrica da Secretaria de Saneamento e Recursos Hídricos do Governo do Estado de São Paulo, sendo governador o tucano Geraldo Alckmin (PSDB).

“Fica a Sociedade de Amigos Marinas do Atibaia autorizada a utilizar recursos hídricos no Condomínio Ribeirão do Vale, para fins de lazer e paisagismo”. O despacho informa ainda que a água do ribeirão da Cachoeirinha pode ser captada à razão de 97,42 m³/hora, durante as 24 horas do dia, todos os dias e meses do ano.

Dá um total de 97.420 litros captados por hora. Ou 2.338.080 litros por dia. Ou 70 milhões de litros por mês. Ou 840 milhões de litros por ano.

O delírio paisagístico também se expressa na decoração do condomínio. Foto: Mídia NINJA

Faça chuva ou faça sol, a água do Ribeirão da Cachoeirinha, água limpa que vem do alto da serra, será desviada por entre os canais artificiais que atravessam o condomínio, para só então ser lançada no Rio Atibaia, que abastece 95% de Campinas (SP), e precisa ser frequentemente socorrido por água do Sistema Cantareira (esse falido), já que se encontra em níveis críticos.

As palavras “crise” e “falência” estabeleceram nos dias atuais uma terrível parceria com as palavras rio, represa, abastecimento e sistema hídrico. E pensar que a palavra “Atibaia”, que dá nome ao rio que recebe as águas do condomínio, veio do tupi, significando rio manso, de águas tranquilas, abundantes, agradáveis ao paladar, “manancial de água saudável”.

É triste.

Em volta da tal Veneza Paulista, nas beiras dos rios, mais da metade da mata nativa já foi convertida em plantações de Eucalyptos urophylla, destinadas à produção de lenha e carvão, fonte energética para alimentar os fornos das pizzarias e padarias da Região Metropolitana de São Paulo.

O resultado dessa devastação toda, que acaba em pizza, tem sido a redução espetacular e veloz do total de chuvas na região. Em apenas vinte anos (de 1985 a 2005), o total de precipitações pluviométricas ali caiu de 1.800 mm por ano para uma média de 1.200 mm por ano.

Quando tudo acabar, entretanto, se comprarmos nosso chalé no condomínio, poderemos dizer, como num filme: “Nós sempre teremos Veneza…”

Mas cadê a graça de viver assim?

Geoengineering report: Scientists urge more research on climate intervention (Science Daily)

Date: February 10, 2015

Source: University of Michigan

Summary: Deep cuts in greenhouse gas emissions, while necessary, may not happen soon enough to stave off climate catastrophe. So, in addition, the world may need to resort to so-called geoengineering approaches that aim to deliberately control the planet’s climate.


Deep cuts in greenhouse gas emissions, while necessary, may not happen soon enough to stave off climate catastrophe. So, in addition, the world may need to resort to so-called geoengineering approaches that aim to deliberately control the planet’s climate.

That’s according to a National Research Council committee that today released a pair of sweeping reports on climate intervention techniques.

The University of Michigan’s Joyce Penner, who is the Ralph J. Cicerone Distinguished University Professor of Atmospheric Science, served on the committee. Penner studies how clouds affect climate.

The reports consider the two main ways humans could attempt to steer the Earth’s system: We could try to take carbon dioxide out of the atmosphere. Or we could try to reflect more sunlight back into space. The committee examined the socioeconomic and environmental impacts as well as the costs and technological readiness of approaches in each category.

The researchers said that certain CO2-removal tactics could have a place in a broader climate change response plan. But the sunlight reflecting technologies, on the other hand, are too risky at this point. They underscored how important it is for humans to limit the levels of CO2 they put into the atmosphere in the first place, and they called for more research into all climate intervention approaches.

“I, for one, am concerned with the continuing rise in CO2 concentrations without clear efforts to reduce emissions,” Penner said. “The widespread impacts from these increases are readily apparent, and the cost of climate change impacts is likely to be high.

“We may need to employ some of these climate interventions techniques to avoid a catastrophe such as the loss of the Antarctic ice sheets, or even to remain below levels of climate change that are considered dangerous in the political arena.”

Techniques to remove CO2 include restoring forests and adopting low-till farming — both of which trap carbon in plants and soils. Oceans could be seeded with iron to promote growth of CO2-consuming organisms. And carbon could be be sucked directly out of the air and injected underground.

Methods to reflect sunlight include pumping sulfuric compounds into the stratosphere to, in essence, simulate a volcanic eruption; and spraying sea water mist or other finer-than-usual particles over the ocean. Smaller particles lead to brighter clouds, Penner said.

While the committee said that some of the CO2 removal strategies including “carbon capture and sequestration” have potential to be part of a viable plan to curb climate change, it noted that only prototype sequestration systems exist today. Much development would have to occur before it could be ready for broad use.

The scientists caution against dumping iron in the oceans, as the technical and environmental risks currently outweigh the benefits. Similarly, they warned against sunlight-reflecting approaches, also known as “albedo modification.”

These efforts might be able to reduce the Earth’s temperature in just a few years, and they’re relatively cheap when compared to transitioning to a carbon-free economy. But they’d have to be kept up indefinitely and could have numerous negative secondary effects on ozone, weather and human health.

Even in its opposition to sunlight reflecting tactics, the committee still recommended more research into them, as it urged more study of all climate intervention possibilities. Penner was struck by this call to action.

“U.S. agencies may have been reluctant to fund this area because of the sense of what we call ‘moral hazard’ — that if you start down the road of doing this research you may end up relying on this or condoning this as a way of saving the planet from the cost of decreasing CO2 emissions,” Penner said. “But we’ve stated that decreasing emissions must go hand in hand with any climate intervention efforts.”

Penner says the recommendation is a sign of the climate problem’s urgency.

“We need to develop the knowledge base to allow informed decisions before these dangerous effects are upon us,” she said.

The study was sponsored by the National Academy of Sciences, U.S. intelligence community, National Aeronautics and Space Administration, National Oceanic and Atmospheric Administration, and U.S. Department of Energy. The National Academy of Sciences is a private, independent nonprofit institution that provides science, technology and health policy advice under a congressional charter granted to NAS in 1863. The National Research Council is the principal operating arm of the National Academy of Sciences and the National Academy of Engineering.

Epigenética na agricultura é tema de livro (Facesp)

11 de fevereiro de 2015

Por Diego Freire

Agência FAPESP – Pesquisadores da Universidade de São Paulo (USP) estão entre os autores e editores do livro Epigenetics in Plants of Agronomic Importance: Fundamentals and Applications, publicado pela editora Springer, que trata do controle da expressão gênica de plantas de interesse agronômico, como o tomate.

Um dos editores é Juan Armando Casas-Mollano, que conduz no Instituto de Química (IQ) a pesquisa “Caracterização funcional de uma recentemente identificada família de MUT9 kinases in Arabidopsis thaliana e cana-de-açúcar”, com apoio da FAPESP na modalidade Jovem Pesquisador, no âmbito do Programa FAPESP de Pesquisa em Bioenergia (BIOEN).

“O livro reúne informações sobre plantas além das chamadas plantas modelo, como a Arabidopsis, amplamente utilizada em todas as áreas da ciência por ter um genoma pequeno e um ciclo de vida rápido e por ser de fácil manipulação”, disse Casas-Mollano.

A epigenética é o estudo de qualquer transformação na expressão de genes que ocorre sem haver mudança na sequência do DNA. Essas alterações, de ordem química, podem ocorrer na molécula de DNA e em proteínas chamadas histonas, podendo ser herdadas na divisão celular. O fenômeno tem alto impacto na biologia do organismo e na definição de diferentes fenótipos, isto é, da sua morfologia, do seu desenvolvimento e de aspectos do comportamento.

“O livro tem informações detalhadas sobre os mecanismos epigenéticos em plantas de importância agronômica. Essas informações podem trazer contribuições para o desenvolvimento de técnicas de manipulação, inibição ou ativação e seleção de proteínas e vias metabólicas, permitindo criar plantas resistentes a patógenos e a estresse ambiental, além de aumentar a produtividade”, afirmou Casas-Mollano.

O pesquisador é coautor do capítulo Histone H3 Phosphorylation in Plants and Other Organisms, com Izabel Moraes, também do IQ. O capítulo revisa e discute avanços mais recentes no estudo de fosforilação de proteínas histonas em plantas.

A fosforilação é a adição de um grupo fosfato a uma proteína ou a outra molécula, sendo um dos principais elementos nos mecanismos de regulação das proteínas, associada ao silenciamento gênico.

“Trata-se de ‘desligar’ a expressão de um gene por meio de mecanismos que não estejam relacionados à modificação de sua sequência gênica. Dessa forma, um gene que está sendo expresso, ou ‘ligado’, naturalmente é ‘desligado’, conforme a necessidade, por meio da fosforilação”, explicou Moraes.

A pesquisadora investiga no IQ o papel de determinados genes no controle do tempo de floração das plantas, fundamental para o sucesso da sua propagação, no projeto de pós-doutorado Compreendendo o papel das kinases MUT9 na regulação do tempo de floração em Arabidopsis thaliana, realizado com apoio da FAPESP e orientação de Casas-Mollano.

O livro conta ainda com um capítulo de autoria do também pesquisador da USP Fabio Tebaldi Silveira Nogueira, da Escola Superior de Agricultura Luiz de Queiroz (Esalq), que trata da epigenética do tomate. Nogueira conduz em Piracicaba a pesquisa Análise funcional do papel de microRNAs no controle da arquitetura vegetativa e desenvolvimento de frutos, com apoio da FAPESP.

Com chuva, Alckmin adia decisão sobre rodízio de água na Grande SP (Folha de S.Paulo)

FABRÍCIO LOBEL e GUSTAVO URIBE

DE SÃO PAULO

11/02/2015  02h00

O volume de chuvas no início de fevereiro, que já se aproxima da média para o mês, levou o governo Geraldo Alckmin (PSDB) a adiar a decisão sobre a implantação de um rodízio de água na Grande SP.

Nas palavras de um assessor do governo, “a Sabesp não jogou a toalha” e, diante de um cenário com chuvas até o final de março e o avanço simultâneo de algumas obras, será até mesmo possível atravessar o período de seca, de maio a setembro, sem rodízio.

Folha teve acesso a esse “plano antirrodízio”, o mais atualizado da Sabesp, a estatal da água. Ele envolve três pontos-chaves, todos interdependentes, sendo que o primeiro nada mais é do que uma ‘torcida meteorológica’:

1) O ritmo de chuvas de fevereiro, que já superou a metade do esperado para o mês e fez aumentar a entrada de água no sistema Cantareira, tem de ao menos permanecer como está até o fim de março;

2) A ligação da represa Billings com o sistema Alto Tietê precisa ser concluída; a obra prevê 11 km de dutos entre os dois mananciais e, segundo o governo de SP, deverá ficar pronta até maio;

3) A capacidade de interligação entre sistemas terá de ser ampliada. Dessa forma, águas do Guarapiranga e do Alto Tietê, por exemplo, poderão atender moradores hoje abastecidos pelo Cantareira em áreas de Guarulhos, na Vila Maria (zona norte), Mooca (zona leste) e Brás (centro).

Editoria de arte/Folhapress

Com tudo isso, aliado principalmente à política de racionamento por meio da redução da pressão na rede de abastecimento, a Sabesp acredita que poderá manter uma vazão de no mínimo 10 mil litros de água por segundo no Cantareira ao longo de 2015, o suficiente, segundo a estatal, para evitar o início do rodízio –a vazão atual é de 14 mil l/seg.

Qualquer falha em um desses três pontos, porém, provocará a reavaliação desse planejamento. O final de fevereiro, por ora, é o prazo tratado internamente como limite para definir o rodízio.

Questionado ontem (10/02) sobre o tema, Alckmin afirmou que não existe nada definido. “É uma decisão técnica, da Sabesp, que faz o monitoramento diário”.

NOVO ÂNIMO

Até o final de janeiro, quando o volume de chuvas seguia bem abaixo da média histórica e o Cantareira caminhava para um colapso completo, o governo paulista tratava o rodízio apenas como uma questão de tempo.

Foi nesse contexto, por exemplo, que um dirigente da Sabesp falou na possibilidade de um rodízio “pesado”, com cinco dias sem água e apenas dois com na semana.

As chuvas de fevereiro não tiraram o Cantareira de uma situação crítica, mas deram uma leve trégua ao governo.

O sistema operou nesta terça (10) com 6,1% de sua capacidade, após mais uma alta. Esse percentual já inclui duas cotas do volume morto, que são as reservas de água abaixo do nível original de captação.

Para evitar um rodízio em 2015, o governo espera que o sistema chegue ao final de março entre 10% e 12% –com o solo úmido após as recentes chuvas, foram reduzidos os danos do chamado “efeito esponja”, que impede o armazenamento da água da chuva.

Estiagem leva 16,8% dos municípios brasileiros a decretar desastre (UOL)

No Brasil, 16,8% dos municípios estão, oficialmente, em situação de desastre, que inclui os estágios de calamidade pública e emergência, por conta da estiagem. Os dados são do Ministério da Integração Nacional, que centraliza e reconhece decretos do gênero registrados por municípios e Estados em todo o país. O Nordeste lidera a lista dos municípios afetados pela estiagem. No Ceará, por exemplo, 95% dos municípios estão oficialmente em situação de desastre por conta da seca.

De acordo com dados do ministério, dos 5.570 municípios brasileiros, 936 tinham decretos de situação de emergência ou calamidade pública em vigência. Os dados são de 2 de fevereiro, data em que o órgão fez a última atualização das informações. A partir do reconhecimento federal, municípios e Estados em situação de desastre ficam autorizados a contratar serviços e comprar mantimentos em regime emergencial sem precisar fazer licitação.

Segundo o ministério, não é possível fazer uma comparação entre os dados atuais e os da mesma época do ano passado porque as informações não são compiladas diariamente. Ainda de acordo com o ministério, em 2014, 1.265 municípios tiveram seus decretos de situação de emergência ou calamidade pública reconhecidos pelo governo federal. Em 2013, foram 1.514.

A assessoria de imprensa do ministério informa, no entanto, que não é possível afirmar que a estiagem neste início de ano é mais amena que as dos anos anteriores, pois os dados referentes a 2013 e 2014 só foram contabilizados ao final de cada ano.

Situação no Nordeste

Dos 936 municípios brasileiros oficialmente em situação de desastre, 843 estão no Nordeste, o equivalente a 90%. A região Sudeste é a segunda mais afetada, com 94 municípios em situação de desastre. As demais regiões (Norte, Centro-Oeste e Sul) não têm nenhum município com decreto de desastre reconhecido pelo governo federal.

Todos os nove Estados do Nordeste têm municípios com situação de desastre reconhecida pelo governo federal. A Paraíba lidera o “ranking” da estiagem com 197 decretos. Logo depois vem o Ceará, com 176. Em termos percentuais, no entanto, o Estado mais afetado foi o Ceará, onde 95% dos municípios estão, oficialmente, em situação de desastre.

De acordo com a Defesa Civil do Estado do Rio Grande do Norte, onde 91% dos municípios têm decretos de desastre reconhecidos pelo governo federal, algumas cidades estão em “colapso” — sem condições de atender à população.

Segundo o órgão, o governo tenta colocar em atividade 1.700 poços artesianos para minimizar os efeitos da estiagem. Pelo menos três cidades já enfrentam rodízio de água em regime 24/48 (um dia com água para cada dois sem).

Situação no Sudeste

Apesar de a crise hídrica estar afetando o abastecimento de água em municípios da região Sudeste, especialmente no Estado de São Paulo, apenas três municípios paulistas estão na lista do Ministério da Integração Nacional: Cristais Paulistas, Santa Rita do Passa Quatro e Tambaú.

Segundo o Ministério da Integração Nacional, “não há pedidos de reconhecimento federal dos Estados do Rio de Janeiro e São Paulo” esperando por análise dos técnicos do governo federal.

No Sudeste, o Estado mais afetado é Minas Gerais, com 90 municípios em situação de emergência ou calamidade pública. Segundo o ministério, Minas Gerais ainda tem 25 pedidos em análise.

Entenda a diferença entre situação de emergência e calamidade pública:

Situação de emergência

Situação anormal provocada por desastres (chuvas, estiagem, incêndio etc) que causam danos e prejuízos que comprometam apenas parcialmente a capacidade do Estado ou do município afetado de responder à situação

Calamidade pública

Situação anormal provocada por desastres (chuvas, estiagem, incêndio etc) que comprometem substancialmente a capacidade do Estado ou do município afetado responder à situação. Normalmente, quando um Estado ou Município decreta calamidade pública, o governo federal intercede com ações de socorro e transferência de recursos

No Big Bang? Quantum equation predicts universe has no beginning (Phys.org)

(Phys.org) —The universe may have existed forever, according to a new model that applies quantum correction terms to complement Einstein’s theory of general relativity. The model may also account for dark matter and dark energy, resolving multiple problems at once.

The widely accepted age of the , as estimated by , is 13.8 billion years. In the beginning, everything in existence is thought to have occupied a single infinitely dense point, or . Only after this point began to expand in a “Big Bang” did the universe officially begin.

Although the Big Bang singularity arises directly and unavoidably from the mathematics of general relativity, some scientists see it as problematic because the math can explain only what happened immediately after—not at or before—the singularity.

“The Big Bang singularity is the most serious problem of general relativity because the laws of physics appear to break down there,” Ahmed Farag Ali at Benha University and the Zewail City of Science and Technology, both in Egypt, told Phys.org.

Ali and coauthor Saurya Das at the University of Lethbridge in Alberta, Canada, have shown in a paper published in Physics Letters B that the Big Bang singularity can be resolved by their  in which the universe has no beginning and no end.

Old ideas revisited

The physicists emphasize that their quantum correction terms are not applied ad hoc in an attempt to specifically eliminate the Big Bang singularity. Their work is based on ideas by the theoretical physicist David Bohm, who is also known for his contributions to the philosophy of physics. Starting in the 1950s, Bohm explored replacing classical geodesics (the shortest path between two points on a curved surface) with quantum trajectories.

In their paper, Ali and Das applied these Bohmian trajectories to an equation developed in the 1950s by physicist Amal Kumar Raychaudhuri at Presidency University in Kolkata, India. Raychaudhuri was also Das’s teacher when he was an undergraduate student of that institution in the ’90s.

Using the quantum-corrected Raychaudhuri equation, Ali and Das derived quantum-corrected Friedmann equations, which describe the expansion and evolution of universe (including the Big Bang) within the context of general relativity. Although it’s not a true theory of , the  does contain elements from both quantum theory and general relativity. Ali and Das also expect their results to hold even if and when a full theory of quantum gravity is formulated.

No singularities nor dark stuff

In addition to not predicting a Big Bang singularity, the new model does not predict a “big crunch” singularity, either. In general relativity, one possible fate of the universe is that it starts to shrink until it collapses in on itself in a big crunch and becomes an infinitely dense point once again.

Ali and Das explain in their paper that their model avoids singularities because of a key difference between classical geodesics and Bohmian trajectories. Classical geodesics eventually cross each other, and the points at which they converge are singularities. In contrast, Bohmian trajectories never cross each other, so singularities do not appear in the equations.

In cosmological terms, the scientists explain that the quantum corrections can be thought of as a cosmological constant term (without the need for dark energy) and a radiation term. These terms keep the universe at a finite size, and therefore give it an infinite age. The terms also make predictions that agree closely with current observations of the cosmological constant and density of the universe.

New gravity particle

In physical terms, the model describes the universe as being filled with a quantum fluid. The scientists propose that this fluid might be composed of gravitons—hypothetical massless particles that mediate the force of gravity. If they exist, gravitons are thought to play a key role in a theory of quantum gravity.

In a related paper, Das and another collaborator, Rajat Bhaduri of McMaster University, Canada, have lent further credence to this model. They show that gravitons can form a Bose-Einstein condensate (named after Einstein and another Indian physicist, Satyendranath Bose) at temperatures that were present in the universe at all epochs.

Motivated by the model’s potential to resolve the Big Bang singularity and account for  and , the physicists plan to analyze their model more rigorously in the future. Their future work includes redoing their study while taking into account small inhomogeneous and anisotropic perturbations, but they do not expect small perturbations to significantly affect the results.

“It is satisfying to note that such straightforward corrections can potentially resolve so many issues at once,” Das said.

Scientists urge global ‘wake-up call’ to deal with climate change (The Guardian)

Climate change has advanced so rapidly that work must start on unproven technologies now, admits US National Academy of Science

Climate change has advanced so rapidly that the time has come to look at options for a planetary-scale intervention, the National Academy of Science said on Tuesday.

The scientists were categorical that geoengineering should not be deployed now, and was too risky to ever be considered an alternative to cutting the greenhouse gas emissions that cause climate change.

But it was better to start research on such unproven technologies now – to learn more about their risks – than to be stampeded into climate-shifting experiments in an emergency, the scientists said.

With that, a once-fringe topic in climate science moved towards the mainstream – despite the repeated warnings from the committee that cutting carbon pollution remained the best hope for dealing with climate change.

“That scientists are even considering technological interventions should be a wake-up call that we need to do more now to reduce emissions, which is the most effective, least risky way to combat climate change,” Marcia McNutt, the committee chair and former director of the US Geological Survey, said.

Asked whether she foresaw a time when scientists would eventually turn to some of the proposals studied by the committee, she said: “Gosh, I hope not.”

The two-volume report, produced over 18 months by a team of 16 scientists, was far more guarded than a similar British exercise five years ago which called for an immediate injection of funds to begin research on climate-altering interventions.

The scientists were so sceptical about geo-engineering that they dispensed with the term, opting for “climate intervention”. Engineering implied a measure of control the technologies do not have, the scientists said.

But the twin US reports – Climate Intervention: Carbon Dioxide Removal and Reliable Sequestration and Climate Intervention: Reflecting Sunlight to Cool the Earth – could boost research efforts at a limited scale.

The White House and committee leaders in Congress were briefed on the report’s findings this week.

Bill Gates, among others, argues the technology, which is still confined to computer models, has enormous potential and he has funded research at Harvard. The report said scientific research agencies should begin carrying out co-ordinated research.

But geo-engineering remains extremely risky and relying on a planetary hack – instead of cutting carbon dioxide emissions – is “irresponsible and irrational”, the report said.

The scientists looked at two broad planetary-scale technological fixes for climate change: sucking carbon dioxide emissions out of the atmosphere, or carbon dioxide removal, and increasing the amount of sunlight reflected away from the earth and back into space, or albedo modification.

Albedo modification, injecting sulphur dioxide to increase the amount of reflective particles in the atmosphere and increase the amount of sunlight reflected back into space, is seen as a far riskier proposition.

Tinkering with reflectivity would merely mask the symptoms of climate change, the report said. It would do nothing to reduce the greenhouse gas emissions that cause climate change.

The world would have to commit to continuing a course of albedo modification for centuries on end – or watch climate change come roaring back.

“It’s hard to unthrow that switch once you embark on an albedo modification approach. If you walk back from it, you stop masking the effects of climate change and you unleash the accumulated effects rather abruptly,” Waleed Abdalati, a former Nasa chief scientist who was on the panel, said.

More ominously, albedo modification could alter the climate in new and additional ways from which there would be no return. “It doesn’t go back, it goes different,” he said.

The results of such technologies are still far too unpredictable on a global scale, McNutt said. She also feared they could trigger conflicts. The results of such climate interventions will vary enormously around the globe, she said.

“Kansas may be happy with the answer, but Congo may not be happy at all because of changes in rainfall. It may be quite a bit worse for the Arctic, and it’s not going to address at all ocean acidification,” she said. “There are all sorts of reasons why one might not view albedo modified world as an improvement.”

The report also warned that offering the promise of a quick fix to climate change through planet hacking could discourage efforts to cut the greenhouse gas emissions that cause climate change.

“The message is that reducing carbon dioxide emissions is by far the preferable way of addressing the problem,” said Raymond Pierrehumbert, a University of Chicago climate scientist, who served on the committee writing the report. “Dimming the sun by increasing the earth’s reflectivity shouldn’t be viewed as a cheap substitute for reducing carbon dioxide emissions. It is a very poor and distant third, fourth, or even fifth choice. |It is way down on the list of things you want to do.”

But geoengineering has now landed on the list.

Climate change was advancing so rapidly a climate emergency – such as widespread crop failure – might propel governments into trying such large-scale interventions.

“The likelihood of eventually considering last-ditch efforts to address damage from climate change grows with every year of inaction on emissions control,” the report said.

If that was the case, it was far better to be prepared for the eventualities by carrying out research now.

The report gave a cautious go-ahead to technologies to suck carbon dioxide out of the air, finding them generally low-risk – although they were prohibitively expensive.

The report discounted the idea of seeding the ocean with iron filings to create plankton blooms that absorb carbon dioxide.

But it suggested carbon-sucking technologies could be considered as part of a portfolio of responses to fight climate change.

It would involve capturing carbon dioxide from the atmosphere and pumping it underground at high pressure – similar to technology that is only now being tested at a small number of coal plants.

Sucking carbon dioxide out of the air is much more challenging than capturing it from a power plant – which is already prohibitively expensive, the report said. But it still had a place.

“I think there is a good case that eventually this might have to be part of the arsenal of weapons we use against climate change,” said Michael Oppenheimer, a climate scientist at Princeton University, who was not involved with the report.

Drawing a line between the two technologies – carbon dioxide removal and albedo modification – was seen as one of the important outcomes of Tuesday’s report.

The risks and potential benefits of the two are diametrically opposed, said Ken Caldeira, an atmospheric scientist at Carnegie Institution’s Department of Global Ecology and a geoengineering pioneer, who was on the committee.

“The primary concern about carbon dioxide removal is how much does it cost,” he said. “There are no sort of novel, global existential dilemmas that are raised. The main aim of the research is to make it more affordable, and to make sure it is environmentally acceptable.”

In the case of albedo reflection, however, the issue is risk. “A lot of those ideas are relatively cheap,” he said. “The question isn’t about direct cost. The question is, What bad stuff is going to happen?”

There are fears such interventions could lead to unintended consequences that are even worse than climate change – widespread crop failure and famine, clashes between countries over who controls the skies.

But Caldeira, who was on the committee, argued that it made sense to study those consequences now. “If there are real show stoppers and it is not going to work, it would be good to know that in advance and take it off the table, so people don’t do something rash in an emergency situation,” he said.

Spraying sulphur dioxide into the atmosphere could lower temperatures – at least according to computer models and real-life experiences following major volcanic eruptions.

But the cooling would be temporary and it would do nothing to right ocean chemistry, which was thrown off kilter by absorbing those emissions.

“My view of albedo modification is that it is like taking pain killers when you need surgery for cancer,” said Pierrehumbert. “It’s ignoring the problem. The problem is still growing though and it is going to come back and get you.”

Kurt Vonnegut graphed the world’s most popular stories (The Washington Post)

 February 9

This post comes via Know More, Wonkblog’s social media site.

Kurt Vonnegut claimed that his prettiest contribution to culture wasn’t a popular novel like “Cat’s Cradle” or “Slaughterhouse-Five,” but a largely forgotten master’s thesis he wrote while studying anthropology at the University of Chicago. The thesis argued that a main character has ups and downs that can be graphed to reveal the taxonomy of a story, as well as something about the culture it comes from. “The fundamental idea is that stories have shapes which can be drawn on graph paper, and that the shape of a given society’s stories is at least as interesting as the shape of its pots or spearheads,” Vonnegut said.

In addition to churning out novels, Vonnegut was deeply interested in the practice of writing. The tips he wrote for other writers – including “How to write with style” and “Eight rules for writing fiction” — are concise, funny, and still very useful. The thesis shows that Vonnegut’s preoccupation with the nuts and bolts of writing started early in his career.

Vonnegut spelled out the main argument of his thesis in a hilarious lecture, where he also graphed some of the more common story types. (Vonnegut was famously funny and irreverent, and you can hear the audience losing it throughout.) He published the transcript of this talk in his memoir, “A Man Without a Country,” which includes his own drawings of the graphs.

Vonnegut plotted stories on a vertical “G-I axis,” representing the good or ill fortunes of the main character, and a horizontal “B-E” axis that represented the course of the story from beginning to end.

One of the most popular story types is what Vonnegut called “Man in Hole,” graphed here by designer Maya Eilam. Somebody gets in trouble, gets out of it again, and ends up better off than where they started. “You see this story again and again. People love it, and it is not copyrighted,” Vonnegut says in his lecture. A close variant is “Boy Loses Girl,” in which a person gets something amazing, loses it, and then gets it back again.

Creation and religious stories follow a different arc, one that feels unfamiliar to modern readers. In most creation stories, a deity delivers incremental gifts that build to form the world. The Old Testament features the same pattern, except it ends with humans getting the rug pulled out from under them.

The New Testament follows a more modern story path, according to Vonnegut. He was delighted by the similarity of that story arc with Cinderella, which he called, “The most popular story in our civilization. Every time it’s retold, someone makes a million dollars.”

Some of the most notable works of literature are more ambiguous – like Kafka’s “The Metamorphosis,” which starts off bad and gets infinitely worse, and “Hamlet,” in which story developments are deeply ambiguous.

In his lecture, Vonnegut explains why we consider Hamlet, with this ambiguous and uncomfortable story type, to be a masterpiece:

“Cinderella or Kafka’s cockroach? I don’t think Shakespeare believed in a heaven or hell any more than I do. And so we don’t know whether it’s good news or bad news.

“I have just demonstrated to you that Shakespeare was as poor a storyteller as any Arapaho.

“But there’s a reason we recognize Hamlet as a masterpiece: it’s that Shakespeare told us the truth, and people so rarely tell us the truth in this rise and fall here [indicates blackboard]. The truth is, we know so little about life, we don’t really know what the good news is and what the bad news is.

“And if I die — God forbid — I would like to go to heaven to ask somebody in charge up there, ‘Hey, what was the good news and what was the bad news?’”

Common anticholinergic drugs like Benadryl linked to increased dementia risk (Harvard Health Blog)

POSTED JANUARY 28, 2015, 8:55 PM

Beverly Merz, Harvard Women’s Health Watch

One long-ago summer, I joined the legion of teens helping harvest our valley’s peach crop in western Colorado. My job was to select the best peaches from a bin, wrap each one in tissue, and pack it into a shipping crate. The peach fuzz that coated every surface of the packing shed made my nose stream and my eyelids swell. When I came home after my first day on the job, my mother was so alarmed she called the family doctor. Soon the druggist was at the door with a vial of Benadryl (diphenhydramine) tablets. The next morning I was back to normal and back on the job. Weeks later, when I collected my pay (including the ½-cent-per-crate bonus for staying until the end of the harvest), I thanked Benadryl.

Today, I’m thankful my need for that drug lasted only a few weeks. A report published online this week in JAMA Internal Medicine offers compelling evidence of a link between long-term use of anticholinergic medications like Benadryl and dementia.

Anticholinergic drugs block the action of acetylcholine. This substance transmits messages in the nervous system. In the brain, acetylcholine is involved in learning and memory. In the rest of the body, it stimulates muscle contractions. Anticholinergic drugs include some antihistamines, tricyclic antidepressants, medications to control overactive bladder, and drugs to relieve the symptoms of Parkinson’s disease.

What the study found

A team led by Shelley Gray, a pharmacist at the University of Washington’s School of Pharmacy, tracked nearly 3,500 men and women ages 65 and older who took part in Adult Changes in Thought (ACT), a long-term study conducted by the University of Washington and Group Health, a Seattle healthcare system. They used Group Health’s pharmacy records to determine all the drugs, both prescription and over-the-counter, that each participant took the 10 years before starting the study. Participants’ health was tracked for an average of seven years. During that time, 800 of the volunteers developed dementia. When the researchers examined the use of anticholinergic drugs, they found that people who used these drugs were more likely to have developed dementia as those who didn’t use them. Moreover, dementia risk increased along with the cumulative dose. Taking an anticholinergic for the equivalent of three years or more was associated with a 54% higher dementia risk than taking the same dose for three months or less.

The ACT results add to mounting evidence that anticholinergics aren’t drugs to take long-term if you want to keep a clear head, and keep your head clear into old age. The body’s production of acetylcholine diminishes with age, so blocking its effects can deliver a double whammy to older people. It’s not surprising that problems with short-term memory, reasoning, and confusion lead the list of anticholinergic side effects, which also include drowsiness, dry mouth, urine retention, and constipation.

The University of Washington study is the first to include nonprescription drugs. It is also the first to eliminate the possibility that people were taking a tricyclic antidepressant to alleviate early symptoms of undiagnosed dementia; the risk associated with bladder medications was just as high.

“This study is another reminder to periodically evaluate all of the drugs you’re taking. Look at each one to determine if it’s really helping,” says Dr. Sarah Berry, a geriatrician and assistant professor of medicine at Harvard Medical School. “For instance, I’ve seen people who have been on anticholinergic medications for bladder control for years and they are completely incontinent. These drugs obviously aren’t helping.”

Many drugs have a stronger effect on older people than younger people. With age, the kidneys and liver clear drugs more slowly, so drug levels in the blood remain higher for a longer time. People also gain fat and lose muscle mass with age, both of which change the way that drugs are distributed to and broken down in body tissues. In addition, older people tend to take more prescription and over-the-counter medications, each of which has the potential to suppress or enhance the effectiveness of the others.

What should you do?

In 2008, Indiana University School of Medicine geriatrician Malaz Boustani developed the anticholinergic cognitive burden scale, which ranks these drugs according to the severity of their effects on the mind. It’s a good idea to steer clear of the drugs with high ACB scores, meaning those with scores of 3. “There are so many alternatives to these drugs,” says Dr. Berry. For example, selective serotonin re-uptake inhibitors (SSRIs) like citalopram (Celexa) or fluoxetine (Prozac) are good alternatives to tricyclic antidepressants. Newer antihistamines such as loratadine (Claritin) can replace diphenhydramine or chlorpheniramine (Chlor-Trimeton). Botox injections and cognitive behavioral training can alleviate urge incontinence.

One of the best ways to make sure you’re taking the most effective drugs is to dump all your medications — prescription and nonprescription — into a bag and bring them to your next appointment with your primary care doctor.

Anthropologists Release Statement on Humanity and Climate Change (AAA)

February 9, 2015

The American Anthropological Association (AAA) adopted a strong and clear statement on Humanity and Climate Change on January 29, 2015. The statement, based on the final report of the Association’s Global Climate Change Task Force, reveals eight ways anthropologists attack the problems of climate change from an anthropological perspective. The document recognizes climate change as a present reality and an intensifier of current underlying global problems; the markedly uneven distribution of impacts across and within societies; and the fact that humanity’s decisions, actions and cultural behaviors are now the most important causes of the dramatic environmental changes seen in the last century.

“Anthropologists focus on several aspects of climate change research that other scientists do not fully address, specifically the disproportionately adverse impacts on vulnerable populations, the extent to which our current challenges stem from culture and cultural choices on a societal level; and the value of the long record of human development and civilization that can inform our choices for the future,” said Shirley J. Fiske, Ph.D., Chair of the American Anthropological Association Global Climate Change Task Force.

The statement affirms that the global problem of climate change is rooted in social institutions and cultural habits. Solutions and social adaptations therefore require knowledge and insight from the social sciences and humanities. “Resilience and adaptation can be best addressed locally and regionally, by enabling communities to provide knowledge and social capital to construct viable solutions,” said task force member Ben Orlove, Ph.D. While climate change will have a global impact, the impact will fall unevenly; and as climate impacts intensify, public expenditures needed for emergency aid and restoration will escalate.

“It is crucial that we attend to the statement’s message that climate change is not a natural problem, it is a human problem,” said AAA President Monica Heller, Ph.D. in a recent statement. “Anthropologists play a vital role solving this human problem and the AAA is eager to continue to support the work of our members in this area.”

Task force members are Drs. Susan Crate, Carole Crumley, Shirley Fiske, Kathleen Galvin, Heather Lazrus, George Luber, Lisa Lucero, Anthony Oliver-Smith, Ben Orlove, Sarah Strauss and Richard Wilk.

Médium da Fundação Cacique Cobra Coral sofre acidente de carro (O Globo)

Adelaide Scritori estava em Paraibuna quando o seu veículo capotou três vezes e caiu dentro do Rio Paraíba do Sul; com escoriações, ela foi transferida para hospital de São Paulo

POR LUIZ ERNESTO MAGALHÃES

RIO – A médium Adelaide Scritori, responsável pela Fundação Cacique Cobra Coral, sofreu um acidente na tarde deste domingo na cidade de Paraibuna, em São Paulo. Adelaide seguia de Minas Gerais para o Rio acompanhando o leito do Rio Paraíba do Sul para monitorar o nível dos reservatórios. O veículo em que estava perdeu o controle, capotou três vezes e caiu dentro d’água.

De acordo com o porta-voz da fundação, Osmar Santos, ela não corre risco de morte, mas sofreu escoriações por todo o corpo e foi levada para um hospital de São Paulo.

– Alguém intercedeu e protegeu a Adelaide – frisou.

A médium diz incorporar o espírito do cacique Cobra Coral, capaz de controlar o clima. Sobre as previsões, Santos disse que a tendência é de que os níveis dos reservatórios voltem a subir com chuvas frequentes até maio.

– As águas vão rolar. O bloqueio foi rompido, mas o cacique não quer conversa com o ministro de Minas e Energia, Eduardo Braga. Nós advertimos em outubro que, se o governador Geraldo Alckmin prosseguisse com o plano de transposição das águas do Rio Paraíba do Sul, a seca iria voltar – disse.
