By 2050 Asia at high risk of severe water shortages: MIT study (Reuters)

Thu Apr 14, 2016 11:30am EDT

CAMBRIDGE, MASS 

A new study points to the risk that China and India will be facing severe water shortages due to a perfect storm of economic growth, climate change, and demands of fast growing populations by mid century. 

Within 35 years, the countries where roughly half the world’s population lives may be facing what scientists are calling a “high risk of severe water stress”. That translates into billions of people having access to a lot less water than they do today, according to a new study from MIT.

“There is about a one in three chance that if we take no action to mitigate climate or to do anything to curtail any of the factors that go into this water stress metric, there is a one in three chance that you will reach this unsustainable situation by the middle of the century,” said Adam Schlosser, a senior research scientist who co-authored the paper published in the journal PLOS ONE.

“It’s very important to show that all things being equal, all things not changing, if we continue with what we are doing now we are running along a very dangerous pathway,” he added.

The scientists simulated hundreds of scenarios looking into the future and found that on average, the water basins that feed economic growth in China and India will have less water than they do today. At the same time, they say pressure on water resources will continue to grow as populations increase, creating an unsustainable scenario where supply loses out to demand.

“We are looking at a region where nations are really at a very rapid developing stage or they are at the precipice of a very rapid development stage and so you really can’t ignore the growth effect, you just can’t, particularly when it comes to resources,” said Schlosser.

But overshadowing everything else, they say, is climate change. While some models show that the effects of climate change could potentially benefit water resources in Asia, the majority point in the opposite direction.

Schlosser and his colleagues believe it will only exacerbate an already gloomy outlook for the future.

Coal Companies’ Secret Funding of Climate Science Denial Exposed (Eco Watch)

Elliott Negin, Union of Concerned Scientists | April 13, 2016 10:49 am

Peabody Energy—the nation’s largest investor-owned coal company—declared bankruptcy Wednesday. Among the many consequences: the company’s court-ordered disclosures are likely to yield hard evidence of Peabody’s direct links to climate science denial.

After all, that’s what we learned from the bankruptcy filings of two other major U.S. coalcompanies, Arch Coal and Alpha Natural Resources. The companies’ lists of creditors accompanying their chapter 11 bankruptcy filings both cited known climate science deniers. So far, the bankruptcy cases have not revealed the details of these financial relationships. But there is now no doubt the coal companies contracted with these groups and individuals to either make a donation or pay for services.

Recent bankruptcy filings have revealed that Chris Horner, who regularly derides climate science on Fox News Channel, has financial ties to the coal industry.Recent bankruptcy filings have revealed that Chris Horner, who regularly derides climate science on Fox News Channel, has financial ties to the coal industry.

This new evidence is important at a time when coal and oil and gas companies are under increased scrutiny about their ongoing climate science disinformation campaigns. ExxonMobil, for example, currently faces state and possibly federal investigations into whether the discrepancies between what the company knew about climate science and what it told their shareholders and the public amounted to fraud.

Of course, there’s no shortage of historical evidence of the coal industry’s track record of deceiving the public about global warming. In 1991, for example, coal trade associations formed a short-lived front group called the Information Council on the Environment that ran a national public relations campaign downplaying the known risks of climate change. All through the 1990s, coal trade groups also were members of the Global Climate Coalition, an alliance of companies and business groups that disputed the findings of the U.N. Intergovernmental Panel on Climate Change (IPCC) and, later on, helped scuttle the Kyoto Protocol climate treaty. And, more recently, the American Coalition for Clean Coal Electricity paid a lobbying firm to send forged letters to members of Congress from actual nonprofit groups, including the NAACP and the American Association of University Women, espousing fabricated opposition to a 2009 climate change bill.

But such coal company connections have been harder to pin down in the current era of so-called dark money. That’s what makes the latest disclosures so noteworthy: They indicate that coal industry disinformation campaigns have continued even as the scientific evidence that burning fossil fuels is driving climate change has only become stronger.

Revealing Creditor Lists

The creditor list for Alpha Natural Resources—which filed for bankruptcy last August—indicates that the company has been especially active in supporting the denier network. As first reported by The Intercept, Alpha—the fourth largest U.S. coal company—has financial ties with a half dozen denier organizations, some which have direct links to billionaire brothers Charles and David Koch, owners of the coal, oil and gas conglomerate Koch Industries. The Koch-affiliated groups include Americans for Prosperity, the Institute for Energy Research and Freedom Partners Chamber of Commerce, a de facto Koch bank that disburses donations from anonymous, wealthy conservatives to groups that advocate rolling back public health, environmental and workplace protections.

Other Alpha creditors include the U.S. Chamber of Commerce, which questions the legitimacy of climate models; the Heartland Institute, which is probably best known for its billboard likening climate scientists to the serial killer Ted Kaczynski; and the American Legislative Exchange Council (ALEC), which convenes conferences for its state legislator members featuring speakers who distort climate science and disparage renewable energy. One of the speakers at a summer 2014 ALEC conference, for example, was Heartland Institute President Joe Bast, whose slide presentation falsely claimed: “There is no scientific consensus on the human role in climate change” and “The Intergovernmental Panel on Climate Change … is not a credible source of science or economics.”

The Alpha creditor list also includes at least two individuals with links to denier groups. Particularly noteworthy is Chris Horner, an attorney who is closely associated with a number of nonprofit denier groups, including ALEC, the Competitive Enterprise Institute (CEI), the Heartland Institute, the Energy & Environmental Legal Institute (E&E Legal), formerly the American Tradition Institute, and the Free Market Environmental Law Clinic, another Alpha creditor.

Arch Coal, the second largest U.S. coal company, listed ALEC and E&E Legal in its list of creditors when it filed for chapter 11 protection in January. Just last month, the Wall Street Journal reported that the company donated $10,000 to E&E Legal in 2014. E&E Legal’s executive director, Craig Richardson, told the Journal the contribution was for “general support.”

Chris Horner’s Coal Ties Disclosed

The exposure of Horner’s financial ties to coal companies is significant because he is a regular guest on Fox News Channel, which identifies him by his affiliation with CEI or E&E Legal but not by his connection to the coal industry.

Despite his lack of scientific expertise, Horner routinely critiques scientific findings, has called for spurious investigations of climate scientists affiliated with the IPCC and the National Aeronautics and Space Administration and has harassed scientists by filing intrusive open records requests with the universities where they work. As legal counsel for the Energy & Environmental Legal Institute and the Free Market Environmental Law Clinic—which work in tandem—Horner has targeted a number of leading climate scientists, including James Hansenand Katharine Hayhoe. Perhaps his most notorious lawsuit was against the University of Virginia to obtain emails, draft research papers, handwritten notes and other documents related to the work of Michael Mann, lead author of the famous “hockey stick” study demonstrating the link between increased fossil fuel use and rising global temperatures. The Virginia Supreme Court ultimately ruled in favor of the university and Mann, affirming the school’s right to protect the privacy of its researchers from overly broad open records requests.

According to the Wall Street Journal, Alpha paid Horner $18,600 before it declared bankruptcy. Meanwhile, the Free Market Environmental Law Clinic—an Alpha creditor—paid him $110,000 in 2014, $115,865 in 2013 and $60,449 in 2012, according to the clinic’s tax filings.

Besides Alpha and Arch Coal, Horner has ties to other coal companies. Last summer, he was a featured speaker at a private $7,500-a-person golf and fly-fishing retreat sponsored by Alpha, Arch Coal and four other coal companies: Alliance Resource Partners, Consol Energy, Drummond and United Coal. After the event—the 2015 annual Coal & Investment Leadership Forum—attendees received an email from the coal company CEOs praising Horner, according to the Center for Media and Democracy, a nonpartisan political watchdog group that first reported the connection between Arch Coal and E&E Legal. “As the ‘war on coal’ continues,” the email stated, “I trust that the commitment we have made to support Chris Horner’s work will eventually create a greater awareness of the illegal tactics being employed to pass laws that are intended to destroy our industry.”

Given the recent spate of bankruptcies, the companies’ commitment to Horner likely will create a greater awareness of something quite different: that the coal industry—along with the likes of ExxonMobil and Koch Industries—is still funding denier groups to spread disinformation about climate science and delay government action. It is time we held these companies accountable.

Regulators Warn 5 Top Banks They Are Still Too Big to Fail (New York Times)

‘LIVING WILLS’ AT A GLANCE

The Fed and the F.D.I.C. found that the plans of five banks were “not credible.”

  • Failed

  • JPMorgan Chase
  • Bank of America
  • Wells Fargo
  • Bank of New York Mellon
  • State Street
  • Mostly Satisfied

  • Citigroup
  • Split Decision

  • Goldman Sachs
  • Morgan Stanley

The five banks that received rejections have until Oct. 1 to fix their plans.

After those adjustments, if the Fed and the F.D.I.C. are still dissatisfied with the living wills, they may impose restrictions on the banks’ activities or require the banks to raise their capital levels, which in practice means using less borrowed money to finance their business.

And if, after two years, the regulators still find the plans deficient, they may require the banks to sell assets and businesses, with the aim of making them less complex and simpler to unwind in a bankruptcy.

Also on Wednesday, JPMorgan announced a decline in both profit and revenue for the first quarter. Other large banks will report quarterly results this week.

“Obviously we were disappointed,” Marianne Lake, chief financial officer of JPMorgan, said on Wednesday morning.

The results are a particular blow for JPMorgan because it often boasts about the strength of its operations and its ability to weather any crisis. Just last week, Jamie Dimon, the chief executive, bragged in his annual letterthat the bank “had enough loss-absorbing resources to bear all the losses,” under the Fed’s annual stress-test situations, of the 31 largest banks in the country.

But the Fed and F.D.I.C. said on Wednesday that JPMorgan appeared to be unprepared for a crisis in a number of areas. The regulators said, for instance, that the bank did not have adequate plans to move money from its operations overseas if something went wrong in the markets.

The letter also said that JPMorgan did not have a good plan to wind down its outstanding derivative contracts if other banks stopped trading with it.

Ms. Lake said “there’s going to be significant work to meet the expectations of regulators.” But she also expressed confidence that the bank could do so without significantly changing how it does business.

Investors appeared to agree that the verdicts from regulators did not endanger the banks’ current business models. Shares of all of the big banks rose on Wednesday.

Wells Fargo, which is generally considered the safest of the large banks, was the target of unexpected criticism from the Fed and F.D.I.C.

The agencies criticized Wells Fargo’s governance and legal structure, and faulted it for “material errors,” which, the regulators said, raised questions about whether the bank has a “robust process to ensure quality control and accuracy.”

In a statement, Wells Fargo said it was disappointed and added, “We understand the importance of these findings, and we will address them as we update our plan.”

The banking industry has complained that the process of submitting living wills is complex and hard to complete and it has suggested changes.

“A useful process reform might be to do living wills every two or three years, instead of annually,” said Tony Fratto, a partner at Hamilton Place Strategies, a public relations firm that works with the banks. “The time required for banks to produce them and regulators to react to them is clearly too tight.”

But Martin J. Gruenberg, the chairman of the F.D.I.C., said on Wednesday that regulators were “committed to carrying out the statutory mandate that systemically important financial institutions demonstrate a clear path to an orderly failure under bankruptcy at no cost to taxpayers.”

“Today’s action is a significant step toward achieving that goal,” he added.

The Ineluctable Tragedy of Existing

tumblr_nfolu6LbZ81rrajnno1_1280There is something unbearable about the Lacanian teaching; something that makes you want to turn away and flee, or at the very least forget.  It is not his opaque style, though that style performs the very thesis he wishes to articulate.  At its heart, the core Lacanian teaching is that there is no cure for existence, that the horror and dissatisfaction we experience in existence is a structural feature of being a speaking-being rather than an accident that befalls some.  Our introduction into language produces an ineluctable fissure within our being, generating a structural loss, forever fracturing jouissance, condemning us to be creatures of desire and drive.  Desire becomes a hole that can never be filled, that pervades every aspect of our existence, and that haunts the entirety of our world and social relations.  Everywhere we see cries raised to heaven, striving to treat desire, this fissure, as an accident

Stephen Hawking e Zuckerberg lançam projeto para buscar planeta habitável (O Globo)

O Globo, 12/04/2016

Uma ilustração de como deve ser a nave – Divulgação

NOVA YORK, EUA – O físico britânico Stephen Hawking e o bilionário russo Yuri Milner anunciaram nesta terça-feira um projeto de US$ 100 milhões para enviar uma nave até o sistema estelar mais próximo da Terra, o Alpha Centauri, que fica a 4,37 anos-luz de distância. Um dos principais objetivos é encontrar planetas habitáveis fora do nosso sistema solar.

A ideia do projeto “Breakthrough Starshot”, de diretoria composta por Milner e Hawking, além do CEO do Facebook, Mark Zuckerberg, é enviar uma nave minúscula, ou uma “nano nave”, numa viagem de 20 anos, atingindo, segundo eles, um quinto da velocidade da luz. O programa vai testar o know-how e as tecnologias necessárias para o projeto.

O programa prevê a criação de uma nave automatizada pesando pouco mais do que uma folha de papel e impulsionada por uma vela solar não muito maior que uma pipa de criança, mas com uma fibra de apenas algumas centenas de átomos em grossura. Enquanto uma vela normal é impulsionada pelo vento, uma vela solar para uso espacial é impulsionada pela radiação emitida pelo Sol.

A ideia inicial é usar milhares de naves assim, que teriam um “empurrão” de um laser montado na Terra, que emitiria ainda mais radiação para ajudar na impulsão. Os desafios do projeto são muitos, entre eles juntar vários emissores num “grande canhão laser”, montar velas com nanotecnologia e juntar todos os componentes da nave num pequeno pacote de silicone.

“A história humana é feita de grandes saltos. Hoje estamos preparando o próximo grande salto, para as estrelas”, disse Yuri Milner em Londres. Já Hawking afirma que “a Terra é um lugar maravilho, mas pode não durar para sempre. Mais cedo ou mais tarde, devemos olhar para as estrelas. Esse projeto é um importante primeiro passo nessa jornada”.

Doenças sexualmente transmissíveis explicam a monogamia (El País)

Com a ampliação das sociedades, as infecções sexuais se tornaram endêmicas e afetaram os que mantinham muitas relações

DANIEL MEDIAVILLA

13 ABR 2016 – 02:29 CEST

A origem da monogamia imposta ainda é um mistério. Em algum momento na história da humanidade, quando o advento da agricultura e da pecuária começou a transformar as sociedades, começou a mudar a ideia do que era aceitável nas relações entre homens e mulheres. Ao longo da história, a maioria das sociedades tem permitido a poligamia. O estudo sobre caçadores-coletores sugere que, entre as sociedades pré-históricas, era frequente que um grupo relativamente pequeno de homens monopolizasse as mulheres da tribo para aumentar sua prole.

No entanto, aconteceu algo para que muitos dos grupos que conseguiram se sobrepor adotassem um sistema de organização do sexo tão distante das inclinações humanas, como a monogamia. Como se pode ler em várias passagens da Bíblia, a recomendação para resolver conflitos geralmente consistia na morte dos adúlteros por apedrejamento.

Um grupo de pesquisadores da Universidade de Waterloo (Canadá) e do Instituto Max Planck de Antropologia Evolutiva (Alemanha), que publicou nesta terça-feira um artigo sobre o tema na revista Nature Communications, acredita que as doenças sexualmente transmissíveis desempenharam um papel fundamental. Segundo a hipótese, que foi testada com modelos tecnológicos, os pesquisadores sugerem que, quando a agricultura permitiu o surgimento de populações nas quais mais de 300 pessoas viviam juntas, nossa relação com bactérias como a gonorreia ou sífilis mudou.

A sífilis e a gonorreia afetavam a fertilidade em uma sociedade sem antibióticos ou preservativos

Nos pequenos grupos do Plistoceno, os surtos causados por esses micróbios duravam pouco e tinham um impacto reduzido sobre a população. No entanto, quando o número de indivíduos na sociedade é maior, os surtos se tornam endêmicos e o impacto sobre aqueles que praticam a poligamia é maior. Em uma sociedade sem preservativos de látex ou antibióticos, as infecções bacterianas têm um grande impacto sobre a fertilidade.

Essa condição biológica teria dado vantagem às pessoas que se acasalavam de forma monogâmica e, além disso, também teria tornado mais aceitáveis castigos, como os descritos na Bíblia, para indivíduos que desrespeitassem a norma. Eventualmente, nas crescentes sociedades agrárias do início da história da humanidade, a interação entre a monogamia e a imposição de normas para sustentá-la acabaria dando vantagem sob a forma de maior fertilidade para as sociedades que as praticassem.

Os autores do estudo acreditam que estas abordagens, que testam premissas onde se tenta compreender a interação entre as dinâmicas sociais e naturais, podem ajudar a entender não só o surgimento da monogamia imposta socialmente, mas também outras normas sociais relacionadas com o contato físico entre os seres humanos.

Nossas normas sociais não se desenvolveram isoladas do que estava acontecendo em nosso ambiente natural”, afirmou em um comunicado Chris Bauch, professor de matemática aplicada da Universidade de Waterloo e um dos autores do estudo. “Pelo contrário, não podemos compreender as normas sociais sem entender sua origem em nosso ambiente natural”, acrescentou. “As normas foram moldadas por nosso ambiente natural”, conclui.

Macaco com coração de porco? Teste abre espaço para transplante com humanos (UOL)

Do UOL, em São Paulo

Um babuíno sobreviveu por dois anos e meio após ter um coração de porco transplantado em seu abdômen. Em pesquisas anteriores, primatas sobreviviam no máximo 500 dias. O recorde foi divulgado na última terça-feira (5) na revista Nature Communications e abre espaço para transplantes entre suínos e humanos no futuro.

O método utilizou uma combinação de modificação genética e drogas imunossupressoras em cinco babuínos. Os corações dos porcos não substituíam os dos primatas — que continuaram com a função de bombear o sangue, mas estavam ligados ao sistema circulatório por meio de dois grandes vasos sanguíneos no abdômen.

Muitas vezes, o sistema imunológico do receptor rejeita o coração do doador por reconhecê-lo como estranho e, portanto, uma ameaça. Na pesquisa com babuínos, os corações dos porcos foram geneticamente modificados para ter alta tolerância à resposta imune. Os cientistas norte-americanos e alemães também adicionaram uma assinatura genética humana para ajudar a prevenir a coagulação do sangue.

Apenas um dos babuínos atingiu a marca de 945 dias vivo. A média entre os cinco foi de 298 dias. A equipe pensa em estender a pesquisa para a substituição dos órgãos.

Transplantes em humanos

Os cientistas têm feito experiências com transplante de rins, coração e fígados de primatas em seres humanos desde a década de 1960. Nenhum sobreviveu por mais de alguns meses.

Por conta da proximidade genética, os primatas eram os melhores candidatos a doadores. Mas não há uma grande quantidade de macacos criados em cativeiro.

Os corações dos porcos são anatomicamente semelhantes aos corações humanos. Os suínos também crescem rápido e são amplamente domesticados.

Antigas listas de compras viram evidência sobre quando a Bíblia foi escrita (UOL/NYT)

Eliashib, o intendente da remota fortaleza no deserto, recebia suas instruções por escrito, anotações feitas em tinta em cerâmica pedindo que provisões fossem enviadas para as forças no antigo reino de Judá.

Os pedidos por vinho, farinha e óleo parecem listas de compras mundanas, apesar de antigas. Mas uma nova análise da caligrafia sugere que a capacidade de ler e escrever era bem mais disseminada do que antes se sabia na Terra Santa por volta de 600 a.C., perto do final do período do Primeiro Templo. As conclusões, segundo pesquisadores da Universidade de Tel Aviv, pode ter alguma relevância para o debate de um século sobre quando o corpo principal dos textos bíblicos foi composto.

“Para Eliashib: agora, dê a Kittiyim 3 batos de vinho, e escreva o nome do dia”, diz um dos textos, compostos em hebraico antigo usando o alfabeto aramaico, e aparentemente referindo-se a uma unidade mercenária grega na área.

Outra dizia: “E um coro pleno de vinho, traga amanhã. Não atrase. E se tiver vinagre, dê a eles”.

O novo estudo, publicado na “Proceedings of the National Academy of Sciences”, combinou arqueologia, história judaica e matemática aplicada, assim como envolveu processamento de imagens por computador e o desenvolvimento de um algoritmo para distinguir entre os vários autores emitindo as ordens.

Com base na análise estatística dos resultados, e levando em consideração o conteúdo dos textos escolhidos como amostra, os pesquisadores concluíram que pelo menos seis mãos escreveram as 18 mensagens mais ou menos na mesma época. Até mesmo soldados das fileiras mais baixas do exército de Judá, ao que parece, sabiam ler e escrever.

“Há algo psicológico além das estatísticas”, disse o professor Israel Finkelstein, do Departamento de Arqueologia e Civilizações Antigas do Oriente Próximo da Universidade de Tel Aviv, um dos líderes do projeto. “Há um entendimento do poder da alfabetização. E eles escreviam bem, praticamente sem erros.”

O estudo se baseou em um conjunto de cerca de 100 cartas escritas com tinta em pedaços de cerâmica, conhecidos como óstracos, que foram descobertos perto do Mar Morto em escavações do forte Arad, décadas atrás, e datados de cerca de 600 a.C. Isso foi pouco antes da destruição de Jerusalém e do reino de Judá por Nabucodonosor, e o exílio de sua elite para a Babilônia, e antes de quando muitos acadêmicos acreditam que grande parte dos textos bíblicos, incluindo os cinco livros de Moisés também conhecidos como Pentateuco, foram escritos de forma coesa.

A cidadela de Arad era uma frente pequena, distante e ativa, próxima da fronteira com o reino rival de Edom. O forte em si tinha apenas cerca de 2.000 metros quadrados e provavelmente só acomodava cerca de 30 soldados. A riqueza dos textos encontrados ali, registrando movimentos de tropas, provisões e outras atividades diárias, foi criada em um período curto, o que os torna uma amostra valiosa para estudo de quantas mãos diferentes os escreveram.

“Para Eliashib: agora, forneça 3 batos de vinho”, ordenava outro óstraco, adicionando: “E Hananyahu ordena que envie a Beersheba 2 mulas carregadas e envie a massa de pão com elas”.

Um dos argumentos mais antigos para o corpo principal da literatura bíblica não ter sido escrito em nada parecido com sua presente forma até depois da destruição e exílio, em 586 a.C., é que antes não havia alfabetização suficiente e nem escribas suficientes para a realização de uma empreitada tão grande.

Mas se a taxa de alfabetização no forte Arad se repetir por todo o reino de Judá, que contava com cerca de 100 mil habitantes, haveria centenas de pessoas alfabetizadas, sugere a equipe de pesquisa de Tel Aviv.

Isso forneceria a infraestrutura para a composição das obras bíblicas que constituem a base da história e teologia de Judá, incluindo as primeiras versões dos livros do Deuteronômio ao Segundo Livro de Reis, segundo os pesquisadores.

Desde o século 19, os acadêmicos debatem “quando foi escrito?”, disse Finkelstein. “Na própria época ou depois”, ele acrescentou, referindo-se à destruição e exílio.

Nos séculos após a destruição e exílio, até 200 a.C., disse Finkelstein, praticamente não há evidência arqueológica de inscrições em hebraico. Ele disse que esperava que escavações revelassem selos gravados e escritos cotidianos em cerâmica, mesmo que textos mais importantes, como os bíblicos, fossem feitos em materiais perecíveis, como pergaminho e papiro.

Os textos bíblicos escritos nos séculos após 586 a.C., ele sugeriu, provavelmente foram compostos na Babilônia.

Outros acadêmicos alertaram contra extrair conclusões demais a respeito de quando a primeira grande parte da Bíblia foi escrita, com base em extrapolações a partir das taxas de alfabetização antigas.

“Não há um consenso atualmente nos estudos bíblicos”, disse o professor Edward Greenstein, da Universidade Bar-Ilan, perto de Tel Aviv. “O processo de transmissão era muito mais complicado do que os acadêmicos costumam pensar.”

O processo de composição da Torá, segundo Greenstein, parece ter envolvido camadas de reescrições, suplementos e revisões. Apontando para o saber recente da literatura bíblica, ele disse que os escribas podiam registrar os textos principalmente como auxílio à memória, em um mundo onde ainda eram transmitidos oralmente.

“Os textos bíblicos não precisavam ser escritos por muitas pessoas, ou lidos por muitas pessoas, para serem redigidos”, ele disse, acrescentando que os textos não circulavam amplamente.

Para deduzir as taxas de alfabetização, a equipe de pesquisa usou um método que Barak Sober, do Departamento de Matemática Aplicada da Universidade de Tel Aviv, comparou à análise forense de caligrafia adaptada aos tempos antigos.

Os matemáticos pegaram 16 cacos de cerâmica de Arad que eram mais ricos em conteúdo (dois apresentavam inscrições em ambos os lados). Dois dos textos lembravam uma chamada, apenas listando as pessoas presentes, e foram claramente escritos no posto avançado no deserto; outros foram compostos em outro lugar.

Muitas das cartas em aramaico não eram claras, de modo que não era possível dar simplesmente entrada dos dados em um computador. Em vez disso, os pesquisadores conceberam uma forma de reconstruí-las. Então as letras de pares de textos foram misturadas e o algoritmo as separou com base na caligrafia.

Se o algoritmo dividisse as letras em dois grupos claros, os textos eram contados como tendo sido escritos por dois autores. Quando o algoritmo não distinguia entre as letras e as deixava juntas em um grupo, nenhuma posição era tomada; elas podiam ter sido escritas pela mesma mão ou, possivelmente, por duas pessoas com estilo semelhante.

Um cálculo conservador revelou pelo menos quatro autores, e seis quando o conteúdo foi levado em consideração, como quem estava escrevendo para quem.

Outro óstraco foi endereçado a um homem chamado Nahum. Ele foi instruído a ir “até a casa de Eliashib, filho de Eshiyahu” para pegar um jarro de óleo, para enviá-lo a Ziph “rapidamente, o lacrando com seu selo”.

An Heir to a Tribe’s Culture Ensures Its Language Is Not Forgotten (New York Times)

Mr. Grant estimates that thousands of students have read the books and taken courses on the language, first through informal workshops held in the nation’s capital, Canberra, from the early 1990s. In December 2015, at a branch of Charles Sturt University in Wagga Wagga, New South Wales, students completed the first-ever course in Wiradjuri.

 To a great extent, Mr. Grant is carrying out a promise to his beloved grandfather, who singled him out as a youngster as his heir to Wiradjuri culture.

“My grandfather was a Wiradjuri elder,” he said, and was anxious to pass along the culture. “But he was arrested after he called to me in Wiradjuri to come home from the park. ‘Barray yanha, barray yanha,’ ‘Come quickly,’ he called out.”

Mr. Grant was probably 8 or 9 years old the night a local policeman heard his grandfather, Wilfred Johnson, and locked him up. But he does not recall a sense of alarm.

“He was an elegant man,” he said of Mr. Johnson. “He was beautifully dressed, usually in a coat and hat. But he was black. So it wasn’t the first time he had spent the night in jail.”

After the arrest, Mr. Johnson, who spoke seven languages, refused to speak Wiradjuri in public.

“He was a linguist with enormous respect for his own people and culture,” said Mr. Grant, who speaks three languages himself: Italian, which he picked up while working at the sawmill, as well as English and Wiradjuri. “But he told me, ‘Things are different now.’ He would only speak his language in the bush.”

It was during those expeditions into the backcountry that Mr. Grant learned Wiradjuri, as well as tracking and hunting skills. He knows that a echidna’s back feet turn inward, complicating tracking. He can describe how his grandfather made a lasso out of long grass to catch a stunned goanna, a type of lizard, for dinner, and he says a rope laid around a bush house will stop snakes from passing over the threshold.

Lloyd Dolan, a Wiradjuri lecturer who has worked with Mr. Grant, said elders took risks teaching Wiradjuri to their children. Mr. Dolan also learned Wiradjuri from his grandfather. His mother forbade him to speak it at home.

“There was a real fear that the children would be taken away if authorities heard kids speaking the language,” Mr. Dolan, 49, said from his office at Charles Sturt University. “The drive to assimilate Aboriginals into white society was systemic.”

Aboriginal people had no right to vote in elections before 1962, and they were counted as wildlife until a change to Australia’s Constitution in 1967.

Mr. Grant grew up in poverty, his family drifting from place to place: Redfern, a rough-and-tumble Sydney suburb; Griffith, a village 60 miles northwest of Narrandera, where he lives now, and Wagga Wagga, which is 62 miles southeast of that.

He recalls vividly moving from a “humpy,” a dirt-floored makeshift shack, consisting of just a few rooms, on the fringe of a country town, into a house with electricity. “It was the first time we had electricity at home, but it wasn’t on much because we had no money to pay for it,” he said with a laugh.

As a child, Mr. Grant said, he scorned his grandfather’s ways. He was embarrassed to be black. By the time he was 17, in 1957, his grandfather had died, and he had dropped out of school, left home and found a job on the railways.

Soon, he moved from a small town to Sydney, where he says he drank a lot, got a tattoo of a roughly drawn dagger and eventually found himself in jail.

“I cried and cried when that happened,” he said. “I had been drinking and probably brawling, and I didn’t want to be there.”

It was his wife, Betty, now 73, who helped turn his life around. After marrying in August 1962, they spent several weeks living out of a shell of a car on the Aboriginal Three Ways Mission on the fringe of Griffith, in central New South Wales.

Mr. Grant soon found a job at a sawmill, and although an accident mangled two fingers of his left hand, it was steady work. He and his wife started a family.

Around that time, Aboriginal activists began agitating for civil rights. In 1965, Charles Perkins, the first Aboriginal to attend the University of Sydney, led 35 student protesters on a Freedom Ride bus tour around outback country towns. They were pelted with gravel and harassed as they went from small town to small town, where they called for an end to segregated seating on buses and in theaters. They demanded equal service in shops and hotels, and they wanted Aboriginal children admitted to municipal swimming pools with white children.

Six years later, Neville Bonner, a leader from an Aboriginal rights organization, became the first Aboriginal to gain a seat in Australia’s Parliament, filling a Senate vacancy left by a Queenslander who had resigned.

With the help of these small civic changes, Mr. Grant, whose formal education ended at age 15, managed to navigate a way forward for himself and his family. He first found work in Canberra helping Aboriginal children who had skipped school.

Around the same time, there was a push to document Aboriginal culture and language, which was rarely written down. As one of the few who knew Wiradjuri language, he was approached about writing it down. That eventually led him to teaching his language and writing “A New Wiradjuri Dictionary,” published in 2005.

“I was told when you revive a lost language, you give it back to all mankind,” he said, sitting in his kitchen, not far from where the kingfishers darted across the Murrumbidgee.

“We were a nothing people for a long time. And it is a big movement now, learning Wiradjuri. I’ve done all that work. I’ve done all I can.”

Médium dá previsão de nuvens sombrias sobre a Esplanada (UOL)

Leandro Mazzini – Coluna Esplanada

A médium Adelaide Scritori, da Fundação Cacique Cobra Coral, que há décadas diz controlar o tempo em trabalho mediúnico, avisou a expoentes dos três Poderes estar atenta.

E mandou um alerta: Ela também está sub judice, não vai poder ajudar muito, porque ninguém tem feito direito seu trabalho. A FCCC já manteve convênio por anos, sem custos, com o Ministério de Minas e Energia, para monitorar os reservatórios das usinas. Desde a Era José Sarney no Palácio.

Que os políticos reparem as nuvens sombrias que se forjam sobre a Esplanada, nas próximas semanas. A conferir.

Vidente do Poder envia e-mail para Cunha e pede renúncia: fatos novos virão (UOL)

Leandro Mazzini – Coluna Esplanada24/11 02:00

A conhecida médium Adelaide Scritori, criadora da Fundação Cacique Cobra Coral, teve visão de nuvens cinzentas que se forjam com “novos fatos” perturbadores para Eduardo Cunha, presidente da Câmara dos Deputados.

Não titubeou em enviar-lhe um e-mail e sugeriu que ele renuncie, antes que seja tarde e vire alvo para valer do STF.

Adelaide é conhecida do circuito do Poder, no eixo Brasília-SP-Rio. Anuncia que sua fundação faz trabalhos espirituais de controle do tempo, e manteve parcerias (diz sem remuneração) com o Ministério de Minas e Energia e Prefeitura do Rio, entre outros clientes mundo afora.

Ficou famosa ao recomendar ao então presidente José Sarney que evitasse uma viagem programada no avião presidencial porque poderia sofrer um acidente. Cauteloso e supersticioso, Sarney acolheu a dica. A FAB teria descoberto depois uma falha numa peça da aeronave.

What I Learned From Tickling Apes (New York Times)

Laughter? Now wait a minute! A real scientist should avoid any and all anthropomorphism, which is why hard-nosed colleagues often ask us to change our terminology. Why not call the ape’s reaction something neutral, like, say, vocalized panting? That way we avoid confusion between the human and the animal.

The term anthropomorphism, which means “human form,” comes from the Greek philosopher Xenophanes, who protested in the fifth century B.C. against Homer’s poetry because it described the gods as though they looked human. Xenophanes mocked this assumption, reportedly saying that if horses had hands they would “draw their gods like horses.” Nowadays the term has a broader meaning. It is typically used to censure the attribution of humanlike traits and experiences to other species. Animals don’t have “sex,” but engage in breeding behavior. They don’t have “friends,” but favorite affiliation partners.

Given how partial our species is to intellectual distinctions, we apply such linguistic castrations even more vigorously in the cognitive domain. By explaining the smartness of animals either as a product of instinct or simple learning, we have kept human cognition on its pedestal under the guise of being scientific. Everything boiled down to genes and reinforcement. To think otherwise opened you up to ridicule, which is what happened to Wolfgang Köhler, the German psychologist who, a century ago, was the first to demonstrate flashes of insight in chimpanzees.

Köhler would put a banana outside the enclosure of his star performer, Sultan, while giving him sticks that were too short to reach the fruit through the bars. Or he would hang a banana high up and spread boxes around, none of which were tall enough to reach the fruit. At first, Sultan would jump or throw things at the banana or drag a human by the hand toward it, hoping to use him as a footstool. If this failed, he would sit around without doing anything, pondering the situation, until he might hit on a solution. He’d jump up suddenly to put one bamboo stick inside another, making a longer stick. He’d also stack boxes to build a tower tall enough to attain his reward. Köhler described this moment as the “aha! experience,” not unlike Archimedes running through the streets shouting “Eureka!”

According to Köhler, Sultan showed insight by combining what he knew about boxes and sticks to produce a brand-new action sequence to take care of his problem. It all took place in his head, without prior rewards for his eventual solution. That animals may show mental processes closer to thinking than learning was so unsettling, though, that still today Köhler’s name is hissed rather than spoken in some circles. Naturally, one of his critics argued that the attribution of reasoning to animals was an “overswing of the theoretical pendulum” back “toward anthropomorphism.”

We still hear this argument, not so much for tendencies that we consider animalistic (everyone is free to speak of aggression, violence and territoriality in animals) but rather for traits that we like in ourselves. Accusations of anthropomorphism are about as big a spoiler in cognitive science as suggestions of doping are of athletic success. The indiscriminate nature of these accusations has been detrimental to cognitive science, as it has kept us from developing a truly evolutionary view. In our haste to argue that animals are not people, we have forgotten that people are animals, too.

This doesn’t mean that anything goes. Humans are incredibly eager to project feelings and experiences onto animals, often doing so uncritically. We go to beach hotels to swim with dolphins, convinced that the animals must love it as much as we do. We think that our dog feels guilt or that our cat is embarrassed when she misses a jump. Lately, people have fallen for the suggestion that Koko, the signing gorilla in California, is worried about climate change, or that chimpanzees have religion. As soon as I hear such claims, I contract my corrugator muscles (causing a frown) and ask for the evidence. Yes, dolphins have smiley faces, but since this is an immutable part of their visage, it fails to tell us anything about how they feel. Yes, dogs hide under the table when they have done something wrong, yet the most likely explanation is that they fear trouble.

Gratuitous anthropomorphism is distinctly unhelpful. However, when experienced field workers who follow apes around in the tropical forest tell me about the concern chimpanzees show for an injured companion, bringing her food or slowing down their walking pace, or report how adult male orangutans in the treetops vocally announce which way they expect to travel the next morning, I am not averse to speculations about empathy or planning. Given everything we know from controlled experiments in captivity, such as the ones I conduct myself, these speculations are not far-fetched.

To understand the resistance to cognitive explanations, I need to mention a third ancient Greek: Aristotle. The great philosopher put all living creatures on a vertical Scala Naturae, which runs from humans (closest to the gods) down toward other mammals, with birds, fish, insects and mollusks near the bottom. Comparisons up and down this vast ladder have been a popular scientific pastime, but all we have learned from them is how to measure other species by our standards. Keeping Aristotle’s scale intact, with humans on top, has been the unfailing goal.

a

But think about it: How likely is it that the immense richness of nature fits on a single dimension? Isn’t it more likely that each animal has its own cognition, adapted to its own senses and natural history? It makes no sense to compare our cognition with one that is distributed over eight independently moving arms, each with its own neural supply, or one that enables a flying organism to catch mobile prey by picking up the echoes of its own shrieks. Clark’s nutcrackers (members of the crow family) recall the location of thousands of seeds that they have hidden half a year before, while I can’t even remember where I parked my car a few hours ago. Anyone who knows animals can come up with a few more cognitive comparisons that are not in our favor. Instead of a ladder, we are facing an enormous plurality of cognitions with many peaks of specialization. Somewhat paradoxically, these peaks have been called “magic wells” because the more scientists learn about them, the deeper the mystery gets.

We now know, for example, that some crows excel at tool use. In an aviary at Oxford University in 2002, a New Caledonian crow named Betty tried to pull a little bucket with a piece of meat out of a transparent vertical pipe. All she had to work with was a straight metal wire, which didn’t do the trick. Undeterred, Betty used her beak to bend the straight wire into a hook to pull up the bucket. Since no one had taught Betty to do so, it was seen as an example of insight. Apart from dispelling the “birdbrain” notion with which birds are saddled, Betty achieved instant fame by offering proof of tool making outside the primate order. Since this capacity has by now been confirmed by other studies, including one on a cockatoo, we can safely do away with the 1949 book “Man the Tool-Maker” by the British anthropologist Kenneth Oakley, which declared tool fabrication humanity’s defining characteristic. Corvids are a technologically advanced branch on the tree of life with skills that often match those of primates like us.

Convergent evolution (when similar traits, like the wings of birds, bats and insects, appear independently in separate evolutionary branches) allows cognitive capacities to pop up at the most unexpected places, such as face recognition in paper wasps or deceptive tactics in cephalopods. When the males of some cuttlefish species are interrupted by a rival during courtship, they may trick the latter into thinking there is nothing to worry about. On the side of his body that faces his rival, the male adopts the coloring of a female, so that the other believes he is looking at two females. But the courting male keeps his original coloring on the female’s side of his body in order to keep her attention. This two-faced tactic, known as dual-gender signaling, suggests tactical skills of an order no one had ever suspected in a species so low on the natural scale. But of course, talk of “high” and “low” is anathema to biologists, who see every single organism as exquisitely adapted to its own environment.

Now let us return to the accusation of anthropomorphism that we hear every time a new discovery comes along. This accusation works only because of the premise of human exceptionalism. Rooted in religion but also permeating large areas of science, this premise is out of line with modern evolutionary biology and neuroscience. Our brains share the same basic structure with other mammals — no different parts, the same old neurotransmitters.

Brains are in fact so similar across the board that we study fear in the rat’s amygdala to treat human phobias. This doesn’t mean that the planning by an orangutan is of the same order as me announcing an exam in class and my students preparing for it, but deep down there is continuity between both processes. This applies even more to emotional traits.

This is why science nowadays often starts from the opposite end, assuming continuity between humans and animals, while shifting the burden of proof to those who insist on differences. Anyone who asks me to believe that a tickled ape, who almost chokes on his hoarse giggles, is in a different state of mind than a tickled human child has his work cut out for him.

In order to drive this point home, I invented the term “anthropodenial,” which refers to the a priori rejection of humanlike traits in other animals or animallike traits in us. Anthropomorphism and anthropodenial are inversely related: The closer another species is to us, the more anthropomorphism assists our understanding of this species and the greater will be the danger of anthropodenial. Conversely, the more distant a species is from us, the greater the risk that anthropomorphism proposes questionable similarities that have come about independently. Saying that ants have “queens,” “soldiers” and “slaves” is mere anthropomorphic shorthand without much of a connection to the way human societies create these roles.

THE key point is that anthropomorphism is not nearly as bad as people think. With species like the apes — aptly known as “anthropoids” (humanlike) — anthropomorphism is in fact a logical choice. After a lifetime of working with chimpanzees, bonobos and other primates, I feel that denial of the similarities is a greater problem than accepting them. Relabeling a chimpanzee kiss “mouth-to-mouth contact” obfuscates the meaning of a behavior that apes show under the same circumstances as humans, such as when they greet one another or reconcile after a fight. It would be like assigning Earth’s gravity a different name than the moon’s, just because we think Earth is special.

Unjustified linguistic barriers fragment the unity with which nature presents us. Apes and humans did not have enough time to independently evolve almost identical behavior under similar circumstances. Think about this the next time you read about ape planning, dog empathy or elephant self-awareness. Instead of denying these phenomena or ridiculing them, we would do better to ask “why not?”

One reason this whole debate is as heated as it is relates to its moral implications. When our ancestors moved from hunting to farming, they lost respect for animals and began to look at themselves as the rulers of nature. In order to justify how they treated other species, they had to play down their intelligence and deny them a soul. It is impossible to reverse this trend without raising questions about human attitudes and practices. We can see this process underway in the halting of biomedical research on chimpanzees and the opposition to the use of killer whales for entertainment.

Increased respect for animal intelligence also has consequences for cognitive science. For too long, we have left the human intellect dangling in empty evolutionary space. How could our species arrive at planning, empathy, consciousness and so on, if we are part of a natural world devoid of any and all steppingstones to such capacities? Wouldn’t this be about as unlikely as us being the only primates with wings?

Evolution is a gradual process of descent with modification, whether we are talking about physical or mental traits. The more we play down animal intelligence, the more we ask science to believe in miracles when it comes to the human mind. Instead of insisting on our superiority in every regard, let’s take pride in the connections.

There is nothing wrong with the recognition that we are apes — smart ones perhaps, but apes nonetheless. As an ape lover, I can’t see this comparison as insulting. We are endowed with the mental powers and imagination to get under the skin of other species. The more we succeed, the more we will realize that we are not the only intelligent life on earth.

Frans de Waal, a primatologist and professor of psychology at Emory University, is the author, most recently, of “Are We Smart Enough to Know How Smart Animals Are?” from which this essay is adapted.

Despite being ‘the biggest threat facing humanity’ climate change and its impacts fail to make headlines, says study (Science Daily)

Summary:
Even as 60 million people around the world face severe hunger because of El Niño and millions more because of climate change, top European and American media outlets are neglecting to cover the issues as a top news item, says a new research report.

Even as 60 million people around the world face severe hunger because of El Niño and millions more because of climate change, top European and American media outlets are neglecting to cover the issues as a top news item, says a new research report funded by the International Fund for Agricultural Development (IFAD) today.

“It’s incredible that in a year when we have had record temperatures, 32 major droughts, and historic crop losses that media are not positioning climate change on their front pages,” said IFAD President, Kanayo F. Nwanze. “Climate change is the biggest threat facing our world today and how the media shape the narrative remains vitally important in pre-empting future crises.”

The report, “The Untold Story: Climate change sinks below the headlines” provides an analysis of the depth of media reporting around climate change in two distinct periods: two months before the 21st session of the UNFCCC Conference of the Parties (COP21) in Paris, and two months after. Specifically, it explores whether issues connecting climate change, food security, agriculture and migration made headlines, and if so, how much prominence these stories were given.

Among some of its key findings: • Climate change stories were either completely absent or their numbers decreased in major media outlets in Europe and the United States before and after COP21. • Coverage on the consequences of climate change, such as migration, fell by half in the months after COP21 and people directly impacted by climate change rarely had a voice in stories or were not mentioned at all. • News consumers want climate change issues and solutions to be given more prominence in media outlets and, in particular, want more information on the connections between climate change, food insecurity, conflict and migration.

The release of the report comes just days before world leaders gather at the United Nations in New York to sign off on the Paris Agreement coming out of COP21. In December, the agreement made headlines and led news bulletins across the globe. But leading up to COP21 and in the months following it, coverage on climate change significantly fell off the radar of major media outlets across Europe and the United States.

“The research shows how the average news-consuming public want to hear constructive stories that highlight solutions to climate change, yet this is exactly what is missing from major news outlets,” said Sam Dubberley, a former journalist and Director of Kishnish Media Ltd, and the author of the report.

Building on initial research that was conducted on media in France and the United Kingdom in September 2015, the report is augmented by focus group surveys that look at what newsreaders understand about food and climate-related migration and their impression of media coverage provided. The report asks what expert voices were heard throughout the stories and whether farmers or migrants themselves had a voice.

The research findings are drawn from an analysis of the content of news stories across influential and popular media outlets: TF1 and France 2 in France, RAI and LA7 in Italy, BBC and Channel 4 in the United Kingdom and CBS and NBC in the United States, as well as the front pages of print editions of Le Monde and Libération in France, Corriere della Sera and La Repubblica in Italy, The Guardian and Daily Mail in the United Kingdom and the New York Times and USA Today in the United States.

In 2014, IFAD funded a research report that looked at how 19 large global and regional news organizations covered issues related to migration and, in particular, food security and agriculture and how it impacted on migration. It focused on two stories that made headlines over the summer of 2014 — the US/Mexico border crisis and the ongoing conflict in South Sudan, which created a large numbers of migrants. That report also found that the depth of coverage on the topics was lacking, and in particular that the voices of migrants were often left out of the stories.

Ministro da Defesa vai a CPI para constranger antropólogos e defensores de indígenas (Outras Palavras)

Blog do Alceu Castilho

Publicado em 3 de abril de 2016

Em ato voluntário, Aldo Rebelo voltou a se aliar com ruralistas para colecionar delírios que seriam inadequados para um deputado; quanto mais à sua função no governo

Por Alceu Luís Castilho (@alceucastilho)

No que se refere à questão agrária, tema que acompanho de perto, nenhuma vez fiquei tão constrangido ao ver a fala de um político quanto agora, ao assistir o vídeo de Aldo Rebelo na CPI da Funai, na quarta-feira. E olhem que ele tem sérios concorrentes. Tivemos o deputado Luís Carlos Heinze (PP-RS) chamando índios, gays, quilombolas de “tudo que não presta”. E falas absurdas da ministra Kátia Abreu, principalmente do tempo em que era senadora; ou do líder da milícia UDR, hoje senador, Ronaldo Caiado (DEM-GO).

E por que a fala de Rebelo é pior?

Porque ele é ministro da Defesa. Suas curiosas concepções sobre “antropologia colonial” já seriam particularmente bizarras por ele se declarar comunista – ele é um dos líderes do PCdoB. Mas este é um assunto menor: que esses comunistas específicos se virem com sua consciência e com suas leituras, diante das diatribes do ex-deputado. Que se olhem no espelho e tentem encarar, depois disso, uma liderança indígena, um antropólogo sério, sem passar profunda vergonha. Agora, repito: Rebelo é ministro da Defesa. 

E, por isso, sua fala é indefensável. Vejamos.

“Dos três troncos, o indígena é o mais sofrido, o mais esquecido pelo Estado brasileiro. Enquanto os outros troncos alcançaram, de certa forma, seu espaço na construção da sociedade nacional, os índios foram ficando à margem desse processo, e carregando maior as penas e o sofrimento da construção da nossa pátria. Cabe, portanto, esse registro pra que essa injustiça possa ser reparada, para que nós possamos, de forma consequente, socorrer, amparar essa parcela da nossa população. Exatamente para que ela não fique à mercê [eleva a voz] da manipulação de demagogos, da manipulação de interesses espúrios internos e externos, como, lamentavelmente, vem acontecendo.

É preciso que o Estado brasileiro ampare a população indígena do Brasil, para que organizações não-governamentais interesseiras, muitas vezes agentes do próprio Estado, agindo contra o Estado, manipulem o sofrimento e o abandono das populações indígenas. Falo, senhoras e senhores, com a experiência de quem palmilhou, nas fronteiras do Brasil mais remotas da Amazônia, as terras indígenas e quem pôde dialogar com suas populações. E de quem pôde testemunhar, exatamente, aquilo que acabo de dizer. (…)

Nossa tradição, naturalmente, não nega as violências, não nega as brutalidades, não nega as injustiças, não nega tudo que de errado nós fizemos contra as populações indígenas. Mas isso também afirma a natureza da nossa civilização de buscar incorporar, não apenas no sangue, mas na cultura, na história, na literatura, na culinária, no imaginário e na psicologia do nosso povo a presença dos nossos queridos e das nossas queridas irmãs e irmãos indígenas.

Por essa razão, senhores, é inaceitável [eleva novamente a voz] a doutrina esposada por certos setores da antropologia, principalmente da antropologia colonial, antropologia criada na França e na Inglaterra exatamente para melhor realizar o trabalho de dominação das chamadas populações aborígenes. Antropologia que depois foi incorporada pelos exércitos coloniais como parte do esquema de dominação. Essa corrente antropológica neocolonial é que procura apartar da sociedade nacional e da integração à sociedade nacional as populações indígenas. E é preciso que se denuncie com vigor e com coragem, para que o Brasil não se ponha no papel de vítima dos crimes que, de fato, ele não cometeu. Basta aqueles que nós já cometemos.

Essa antropologia que influencia estruturas do próprio Estado brasileiro, que incorpora setores importantes da nossa mídia, que incorpora setores importantes de correntes religiosas trata de estabelecer um abismo entre a sociedade nacional, entre o Brasil e as populações indígenas, contrapondo ao esforço de integração a ideia de segregação. Como se na escala evolutiva da humanidade o índio pudesse ser contido e parado nos estágios anteriores à evolução de toda a humanidade.

Tenho amigos europeus que fazem estudos em populações tribais e que descobriram, aqui na região da Amazônia, como é óbvio, uma população indígena que não sabe contar, que não domina a aritmética como qualquer povo ágrafo. Eu dizia para ele: seus antepassados também não sabiam contar. Contam no máximo 1, 2, 3 e muito. (…) O que eu perguntava para esse amigo antropólogo era o seguinte: as crianças dessa tribo devem ter o direito de aprender matemática? Ou elas devem ter negado esse direito, para que a antropologia continue dispondo de estudo de caso para registrar nas suas teses de mestrado ou doutorado? (…)

A manipulação das causas nobres e justas, como é a causa da proteção dos índios, não é a única no mundo. Ela tem paralelo com a manipulação da causa do meio ambiente. É muito parecido. As potências usam o meio ambiente, as causas indígenas, os direitos humanos, a democracia, a liberdade como usaram o anticomunismo no passado. O que era o anticomunismo? Era o pretexto para se fazer golpes de Estado, para defender interesses econômicos em função da defesa da liberdade e da democracia. Depois que o comunismo deixou de ser o pretexto, porque não era de fato ameaça, eles procuraram outros pretextos: a causa indígena é um deles, o ambientalismo é outro”.   

E assim por diante, como se pode ver no vídeo. De forma voluntária, sem que o ministro Aldo Rebelo tivesse sido convidado ou convocado à CPI, instalada pelos ruralistas para combater direitos indígenas e a reforma agrária. Como porta-voz do governo, portanto?

aldorebelo

Note-se que ele chega a combater a demarcação contínua da Raposa Serra do Sol, em Roraima. Em determinado momento, pergunta: “Quem é índio e quem não é índio onde tudo já se misturou?” E cita um estudo de pedologia na Universidade Federal de Viçosa que considera não existir mais ali uma civilização indígena, “mas uma civilização miscigenada”.

E tem mais: ele se declarou à favor da Proposta de Emenda Constitucional (PEC 215) que transfere ao Congresso o poder de demarcar terras indígenas e quilombolas: “Aldo diz à CPI que é a favor da PEC que muda regras de demarcação de terras“. Uma bandeira de quem? Dos ruralistas.

É como resume o antropólogo Henyo Barretto Filho, do Instituto Internacional de Educação do Brasil: “Se o governo não desautorizar de modo igualmente público e expresso tal depoimento, fica sendo essa a versão do governo sobre os povos indígenas, a política indigenista e o papel da antropologia no reconhecimento dos direitos territoriais”.

Review: In ‘Vita Activa: The Spirit of Hannah Arendt,’ a Thinker More Relevant Than Ever (New York Times)

Hannah Arendt, who died in 1975, was a prolific and unclassifiable thinker, a political theorist, moral philosopher and polemicist of unmatched range and rigor. At least outside academic circles, her posthumous fame — or notoriety — rests on “Eichmann in Jerusalem,” a piece of extended reportage she wrote for The New Yorker in 1963, and on a single phrase associated with it: the banality of evil.

Those words are evoked so often, and in so many contexts, that their specific and controversial original meaning is easily forgotten. Arendt, attending the war crimes trial of Adolf Eichmann, a high-ranking Nazi captured in Argentina by Israeli operatives, was struck by his ordinariness, the bland bureaucratic demeanor seemingly at odds with the enormity of his crimes. Though later research has suggested that Arendt misjudged Eichmann — who was, for one thing, a much more ardent anti-Semite than he seemed to be, sitting in the dock — the idea that great horror can spring from mundane roots has proved tenacious and perpetually relevant.

Vita Activa: The Spirit of Hannah Arendt,” a vigorous and thoughtful new documentary by Ada Ushpiz, frames its inquiry into Arendt’s career with her encounter with Eichmann. But its focus is much wider than the still-potent debate over “Eichmann in Jerusalem,” which was widely and fiercely attacked for what critics took to be its trivialization of Eichmann’s deeds and its lack of sympathy for his victims. Though both Arendt’s defenders and detractors are heard from, Ms. Ushpiz’s film situates the Eichmann episode within a broad and rich portrait of an intellectual determined to use the tools of rationality to comprehend historical events that seem to defy all reason.

The title insists, as Arendt herself always did, that thinking is a form of action. The “spirit” conjured — through Arendt’s own words, the recollections of students, disciples and friends, and carefully chosen archival images — is one of relentless and passionate mental activity. Ms. Ushpiz is determined to rescue her subject from the banality of biography. The details of Arendt’s childhood, education, romantic life and professional activity are not ignored, but they nearly always illuminate her ideas.

Arendt was born into an assimilated German-Jewish family in 1906. Her early association with the philosopher Martin Heidegger — she was his lover as well as his student — has been another source of controversy, given his subsequent collaboration with the Nazis and their racial policies. Arendt herself fled Germany in 1933, and much of her subsequent writing wrestles with the lethal contradictions of a homeland that seemed by turns to represent the pinnacle of civilization and the depth of barbarism.

“The Origins of Totalitarianism,” her 1951 tour de force, represents her most sustained attempt to understand German fascism and Soviet Communism not as metaphysical catastrophes but as political developments, as aspects of modernity rather than as horrific exceptions to its progress. Recent scholarship has challenged some of her arguments, but the analytic framework of the book remains powerful and disconcertingly topical.

“Vita Activa,” while it will surely satisfy and provoke students of 20th-century intellectual history, feels more urgent than most documentaries of its kind. Some of Ms. Ushpiz’s methods are a little questionable — I was bothered by the way she slipped artificial, ambient sound into silent footage — but she shows impressive coherence and fair-mindedness in her approach to Arendt, succumbing neither to hagiography nor to facile skepticism. Instead, she subtly draws the viewer’s attention from the past to the present, using judiciously chosen passages from Arendt’s letters and published work.

Two insights stand out in painful relief. The first is Arendt’s contention that the lethally dehumanizing logic of totalitarianism originated partly in the massive displacement of populations after World War I. The refugees created by that conflict were not only stateless but “rightsless,” regarded by the nations of Europe not as citizens in need of protection but as a problem to be solved. A century after that war, Europe is again in the midst of a refugee crisis, the political consequences of which are not yet fully known.

Arendt was also concerned with the ways certain totalitarian tendencies and attitudes could persist in democratic societies, and “Vita Activa” includes some especially chilling implications for the current state of American politics. Totalitarianism rested, in Arendt’s view, above all on the systematic refusal to engage reality, on the substitution of ideological fantasy and outright fiction for reason and empiricism. To risk understatement, those tendencies have hardly disappeared from modern society, and may even be stronger than they were at the end of Arendt’s life.

As nuvens marcam as fronteiras dos ecossistemas (El País)

Padrões de nebulosidade desenham o mapa das paisagens bioclimáticas e a distribuição das espécies

MIGUEL ÁNGEL CRIADO

O geógrafo Adam Wilson e o ecologista Walter Jetz observaram as nuvens para saber a vida que existe sob elas. Os dois cientistas usaram imagens de satélites tiradas duas vezes ao dia durante os últimos 15 anos para criar um atlas das nuvens e relacionaram esse mapa com a biodiversidade do planeta, desenhando desde os limites dos grandes biomas (paisagens bioclimáticas) até a distribuição geográfica das diferentes espécies.

Suspensas lá em cima, as nuvens são um elemento fundamental da climatologia. Sua presença anuncia umidade, chuvas, água para as plantas, bosques e florestas, explosão de vida… Por outro lado, sua ausência caracteriza paisagens mais secas e desoladas, seja nos desertos ou no interior da Antártida. Foi essa conexão entre clima e biodiversidade que levou Wilson, professor da Universidade de Buffalo, e Jetz, pesquisador de Yale (ambas nos EUA), a buscar uma forma de detectar os padrões e dinâmica globais das nuvens mais eficiente do que os sistemas atuais.

Encontraram a solução nas fotografias da Terra tiradas há anos pela NASA. Concretamente, eles usaram os dados acumulados pela missão MODIS, siglas do espectroradiômetro de imagens de resolução média, um instrumento científico que vai a bordo de dois satélites chamados Terra e Aqua. O primeiro foi colocado em órbita em 1999, o segundo, quatro anos depois. Os dois circundam o planeta em uma órbita de polo a polo tirando fotografias sincronizadas para que Terra sobrevoe o equador de manhã e Aqua o faça pela tarde em sentido oposto. A cada dois dias fotografam todo o planeta em alta resolução.

As regiões equatoriais são as de maior concentração anual de nuvens e menor variação mensal

Com esse alcance global e uma resolução de até menos de um quilômetro, os dois pesquisadores criaram seu atlas das nuvens. Em sua versão online é possível observar a frequência anual de nebulosidade, entendida como a porcentagem de dias com mais nuvens do que claros, em cada latitude. Também se observa a variação mensal, por estação e anual.

Em um primeiro olhar (ver fotografia), é possível observar uma correlação entre a latitude e padrões de nebulosidade. Dessa forma, a América equatorial, a bacia do rio Congo na África e o sudeste da Ásia são as regiões com mais nuvens do planeta, até 80% dos dias são nublados. Mesmo que as espécies que habitam esses grandes biomas possam ser diferentes, são ecossistemas que possuem diversas características em comum.

O mapa permite observar também a variação inter-anual. Enquanto as selvas equatoriais apresentam poucas variações que nunca superam 5% de um mês ao outro, os biomas monçônicos da Índia e o sahel africano são os que sofrem maiores diferenças entre os meses nublados e os claros, o que corresponde à temporada de chuvas e a temporada seca.

“Quando visualizamos os dados, destacou-se a claridade com a qual pudemos ver os muitos e diferentes biomas da Terra tendo por base a frequência e o momento dos dias nublados dos últimos 15 anos”, diz Wilson. “Quando passamos de um ecossistema a outro, essas transições mostram-se muito claramente e o melhor é que esses dados permitem observar diretamente esses padrões com uma resolução de um quilômetro”, acrescenta.

Essa resolução é uma das maiores contribuições da pesquisa. Pode ser óbvio que a bacia do Congo tenha muitos dias com nuvens, mas com as imagens de satélites é possível observar as diferenças locais, entre a margem norte e sul de um rio e as encostas leste e oeste de uma montanha, por exemplo. Era possível conseguir esse grau de detalhamento nas áreas mais desenvolvidas do planeta, mas não nas menos, que são exatamente as que possuem maior riqueza biológica.

Até agora, os estudos sobre biodiversidade eram baseados na observação direta dos pesquisadores (e, portanto, muito parcial) e as extrapolações de outros sistemas de coleta de dados. Um dos maiores são as estações meteorológicas que, com seus dados de umidade, vento, precipitações, desenham a paisagem climática nas quais vivem as diferentes espécies. Mas a rede de estações também não é suficientemente compacta, de modo que os cientistas precisam interpolar a partir de dados às vezes muito locais e dispersos.

“Compreender os padrões espaciais da biodiversidade é fundamental se queremos tomar decisões balizadas sobre como proteger as espécies e gerir a biodiversidade e seus muitos serviços para o futuro”, diz Jetz. Mas acrescenta: “para as regiões que possuem mais diversidade biológica, existe uma escassez real de dados dos locais”.

Esse estudo original, publicado na PLoS Biology, mostra também a íntima e frágil relação entre as nuvens e os chamados bosques nublados. É que essas selvas com a presença constante ou pelo menos regular de nuvens baixas como nevoeiro também não escapam à detecção dos satélites. Essas regiões são ricas em endemismos, de modo que a alteração dos padrões de nebulosidade pela ação humana e a mudança climática pode ter consequências catastróficas.

Os pesquisadores, que não pretendem substituir os modelos existentes, mas acrescentar mais uma camada de conhecimento, quiseram comprovar a validade de seu atlas das nuvens para indicar não só os limites de um determinado ecossistema, mas a distribuição geográfica de duas espécies. Uma é o pequeno trepatroncos montano, um pássaro das selvas montanhosas do norte da América do Sul. A outra é a protea real, um arbusto da região de clima mediterrâneo da África do Sul. Nos dois casos, o que viram nas nuvens foi mais preciso do que os dados oferecidos pelos modelos baseados em registros de precipitações e temperatura.

The Stark Realities of Baked-In Catastrophes (Collapse of Industrial Civilization)

02 Apr 2016

Joe-Webb-Greetings-From-California

In a civilization gone mad with delusions of grandeur, we’re left with tatters of human sociability held together by rancid mythologies.

Despite human fossil fuel burning recently reported to be “flat”, CO2 levels have been on a tear for the last six months, reaching new worrying levels which have some wondering whether permafrost melt may be contributing to the unusually high spike if no decline happens soon. The giant holes in Siberia serve as an ominous sign. Considering that the current El Niño is contributing only 10% to what we are now seeing, runaway global warming may be accelerating worldwide. But don’t worry, Warren Buffett says climate change is no more of a problem than the Y2K bug and will be profitable through increased premiums and inflation.

Ever dire studies continue to reaffirm worst case scenarios, making clear to anyone paying attention that Earth in the next century will be unrecognizable from its current state. Basic planetary geography and atmospheric conditions will be altered through warming oceans and rising sea levels which are now increasing faster than at any time in the past 2800 years. On average, sea levels were between 50 and 82 feet higher the last time CO2 levels were at 400ppm. Glaciologist Jason Box expects ice melt from the West Antarctic to become the biggest contributor to sea level rise in the coming decades due to a feedback loop not in the climate models. CO2 levels have been increasing around 3ppm per year, a twentyfold increase since pre-industrial times when the highest recorded increase was 0.15 ppm per year. We’ve long since passed the tipping point of melting Arctic summer sea ice; 300-350 ppm of CO2 was the threshold for many parts of the climate. These changes are irreversible on a timescale of human civilizations. Even if all human industrial activity magically ceased today, the footprint man has already left will be felt for eons.

In our warming world, the hydrologic cycle is changing and creating extreme weather; crop-destroying droughts and floods are becoming more frequent. The Jet Stream is transforming into something different, becoming wavier with higher ridges and troughs prone to stagnating in the same region. As global temperatures rise over time, hotter air will be trapped under these layers of high pressure from a mangled Jet Stream, cooking everything to death. Rising winter temperatures are beginning to destroy the “winter chill” needed for many fruit and nut trees to properly blossom and produce maximally. Climate change is also disrupting flower pollination and pushing fish toward North/South poles, robbing poorer countries at Equator of crucial food resources. In a new study, marine scientists are surprised to find a disturbing trend in the increasing numbers of a specific type of phytoplankton, coccolithophores, which have been “typically more abundant during Earth’s warm interglacial and high CO2 periods.”

Homo sapiens have only been on the planet for the equivalent of a few seconds in geologic time but have managed to overwhelm and foul up all of earth’s natural processes and interdependencies, leaving a distinct layer in the sedimentary record. There is nothing modern humans do that is truly sustainable. Here are a few glaring examples:

No amount of reafforestation or growing of new trees will ultimately off-set continuing CO2 emissions due to environmental constraints on plant growth and the large amounts of remaining fossil fuel reserves,” Mackey says. “Unfortunately there is no option but to cut fossil fuel emissions deeply as about a third of the CO2 stays in the atmosphere for 2 to 20 millennia.

ambiente-01

Relying on machines for answers to the existential problems of a species run amok with planet-destroying tools and weaponry is rather ironic and tragic. We’re locked-up inside a complexity trap of our own making. The human propensity for tool-building coupled with our discovery of fossil fuels has created a set of living arrangements in which we are now enslaved to those machines and tools. The globalized capitalist economy externalizes its destruction and atrocities, keeping the masses in a state of ignorance and denial. Our corporate overlords are not conscientious citizens, but mindless organizations whose sole purpose is to grow profits no matter the external damage done to society and the environment. Between the economic oil hitmen who ensure that profits flow smoothly and GOP politicians who openly espouse their science illiteracy, a hospitable climate for future humans seems remote. Hopeful delusions have given way to the stark reality of our predicament as scholars like Noam Chomsky who originally started his career fighting for a modicum of social justice have now set the bar at just the chance of human survival. Despite the best efforts of scientists, environmentalists, and activists, the wealthy countries most able to do something won’t “get it” until famine, disease, and war come to their country. All is being left for the almighty ‘free market’ to sort out at the same time that climate change, a conflict multiplier, ramps up.

The sixth mass extinction gathers steam and climate inertia works to catch up to the catastrophic ecological collapse already baked-in. All the while, modern man engages in the spectacle of tribal politics(building walls, exuding military strength, recapturing past glories of their nation) and presidential candidates discuss the size of their penis.

For those who come to understand modern man’s predicament, it can either be the ultimate mind fuck or an epiphany that helps a person appreciate the fragility of life, the urgency of living in the here and now, and the grand cosmic joke of a global, hi-tech civilization that arose from the burning of ancient fossil remains only to have those fumes become a deadly curse, extinguishing any trace of our lofty accomplishments…

The fossil record, Plotnick points out, is much more durable than any human record.

As humanity has evolved, our methods of recording information have become ever more ephemeral,” he said. “Clay tablets last longer than books. And who today can read an 8-inch floppy?” he shrugged. “If we put everything on electronic media, will those records exist in a million years? The fossils will.

Amid Climate-Fueled Food Crisis, Filipino Forces Open Fire on Starving Farmers (Common Dreams)

Published on Monday, April 04, 2016 by Common Dreams

Police and army forces in the Philippines unleashed bullets on a starving crowd, killing 10, for demonstrating for drought relief

Police and army forces shot at about 6,000 starving farmers and Lumad Indigenous people demonstrating for drought relief in the Philippines on Friday, ultimately killing 10. Observers characterized the security forces’ action as “a strafing.”

“The government’s response to hunger is violence,” said Zeph Repollo, Southeast Asia campaign coordinator for 350.org, in an email to Common Dreams.

Three protesters were immediately killed, and by Monday the death toll had risen to 10 as more demonstrators succumbed to injuries.

“We don’t have anything to eat or harvest. Our plants wilted. Even our water has dried up.”
—Noralyn Laus, demonstrating farmer

The farmers and Indigenous people had been blockading a highway in the Cotabato province for four days in a desperate plea for government aid, after this winter’s record-breaking temperatures produced a three-months-long drought that has destroyed their crops and now threatens their lives.

The demonstrators were asking the government to provide 15,000 sacks of rice to ease the hunger crisis. Provincial governor Emmylou Mendoza has refused to engage the protesters.

“The government’s policy of  systematic land grabbing combined with the intensified El Nino pushed our farmers and indigenous peoples to heighten their struggles with sweat and blood in defense of their right to land and life,” wrote Repollo in a statement.

On Monday, local farmer Noralyn Laus gave Democracy Now! a firsthand account of the disaster:

“Why we came down here is not to make trouble. We just want to demand for rice, because of the situation of El Niño is leaving our tribes hungry. What happened yesterday, we didn’t start it. They started it by beating us. We wouldn’t be angry if we weren’t beaten up or attacked. We’re having a crisis. We don’t have anything to eat or harvest. Our plants wilted. Even our water has dried up.”

“Our farmers—the country’s food producers—are battered the hardest and are left in poverty and hunger,” Rapollo said. “Civil disobedience will continue to escalate until the government stops playing deaf and blind to the genuine cry of the people.”

Seventy-eight people were still under arrest on Monday, Rapollo said, and a local Methodist Church is sheltering many protesters who escaped the bullets. Rapollo also reported that no members of the armed forces have been relieved of duty or investigated for Friday’s shooting.

The state-sponsored violence in the Philippines portends what turmoil may come as the planet continues to warm, creating more disastrous, extreme weather events worldwide, environmental activists note.

“The conditions that prompted the 3-day blockade gives us a glimpse of what’s ahead if decisive and just actions in addressing climate change remain in the periphery,” said Repollo.

“This is not a distant reality to anywhere in the world,” Repollo wrote to Common Dreams, “unless we change the system that feeds [on] hunger, injustices, and climate catastrophe.”

[Esse título é uma piada. Não é de estranhar que o jornalista português não saiba o mínimo necessário para falar sobre indígenas sem cometer o erro absurdo de considera-lo o “último” chefe índio, uma vez que os jornalistas brasileiros, que estão tão próximos das populações indígenas, tampouco sejam capazes de evitar tais gafes.-RT]

Morreu o último chefe índio dos Estados Unidos

Joseph Medicine Crow, último chefe da tribo Crow, morreu com 102 anos de idade. Embora tenha nascido em 1913, era considerado uma memória viva do século XIX.

 Joseph Medicine Crow foi educado para ser um guerreiro, absorveu na sua tribo as narrativas de feitos heróicos, em especial a batalha nas margens do rio Little Bighorn, em 1876. Ouviu essas narrativas de guerreiros índios que ainda tinham participado na batalha. Recordavam-na como rara vitória que fora, dos índios sobre as tropas brancas, ocasionada pela aliança entre cheyennes sioux, contra a prática do general George Armstrong Custer, que habitualmente massacrava aldeias índias inteiras.

Custer, retratado sem contemplações no filme Little Big Man, protagonizado por Dustin Hoffman, foi morto na batalha, juntamente com mais de duas centenas de militares norte-americanos.

Na reserva de Lodge Grass, Montana, Joseph Medicine Crow foi treinado desde os seis anos de idade pelo seu avô, Cauda Amarela, para continuar as proezas guerreiras de chefes como Touro Sentado e Cavalo Louco, os dois líderes das tribos coligadas para a vitória de Little Bighorn. O avô fazia-o correr descalço sobre a neve, para criar resistências.

Segundo a nota publicada no New York Times por ocasião da sua morte, Medicine Crow seguiu, contudo, um outro caminho, numa época em que a resistência à ocupação branca já tinha terminado. Foi um dos primeiros índios estudarem e licenciou-se em antropologia em 1939. Mas depois veio a Segunda Guerra Mundial e voltou a emergir Crow, o guerreiro índio.

Entre os seus feitos de guerra conta-se o de roubar cavalos num acampamento inimigo e o de vencer em combate corpo-a-corpo um soldado alemão, a quem finalmente decidiu poupar a vida. Num livro publicado em 2006, Medicine Crow explicava que “fazer a guerra é a nossa arte suprema; mas para os índios da planície fazer a guerra não consiste em matar. É tudo uma questão de inteligência, de liderança e de honra”.

Quando voltou da guerra na frente europeia, Joseph Medicine Crow foi nomeado pelo conselho tribal como historiador da tribo. Diz-se que era dotado de uma memória prodigiosa e que conseguia, muitos anos depois, reproduzir grande parte das conversas que tivera com seis batedores índios que chegara a conhecer e que estiveram ao serviço do general Custer na batalha de Little Bighorn.

O empenhamento de Medicine Crow em cultivar as tradições da sua tribo como parte integrante de uma nação americana resultante do extermínio da população indígena valeu-lhe numerosos louvores e condecorações, mais recentemente por parte do presidente Barack Obama. Entre os elogios fúnebres que lhe fizeram os seus conterrâneos conta-se o do senador Steve Daines, nestas palavras algo ambíguas: “O espírito de Medicine Crow, a sua humildade e as realizações da sua vida, deixam uma marca duradoura na história de Montana”.

Mudanças climáticas provocarão prejuízo de US$ 2,5 trilhões (O Globo)

05/04/2016, por O Globo

Colheita de cana de açúcar: rombo acontecerá mesmo se os países cumprirem as metas voluntárias apresentadas na conferência climática de Paris, em dezembro de 2015 – Paulo Fridman/Bloomberg/18-9-2014

RIO — As mudanças climáticas podem afetar investimentos equivalentes a US$ 2,5 trilhões da economia mundial até 2100, segundo um estudo publicado ontem na revista “Nature Climate Change”. O prejuízo seria resultado do aumento da temperatura em 2,5 graus Celsius até o fim do século, em relação aos níveis pré-industriais. Esta quantia é equivalente à metade do valor atual das empresas de combustíveis fósseis. Se os termômetros avançarem além de 2 graus Celsius — valor máximo admitido pelos climatologistas —, a economia mundial sofreria um rombo de US$ 1,7 trilhão.

Entre os meios de destruição mais comuns ligados às mudanças climáticas estão o aumento do nível do mar — que afeta principalmente setores da economia atuantes na zona costeira —, além de secas e tempestades, capazes de interromper atividades de diferentes ramos do mercado.

A pesquisa concentrou-se principalmente em investimentos ligados a petróleo, carvão e gás, recursos que serão perdidos se os países insistirem na adoção de combustíveis fósseis, em de vez de optar por energias sustentáveis.

De acordo com o Instituto de Pesquisa Grantham sobre Mudanças Climáticas, que elaborou o estudo, seus cálculos são a primeira estimativa do impacto causado pelo aquecimento global sobre ativos financeiros.

As projeções, realizadas com o uso de modelos matemáticos, foram baseados em um valor estimado de US$ 143,3 trilhões em ativos não bancários globais em 2013, valor determinado por economistas.

Considerando as atuais emissões de gases-estufa, os climatologistas indicam que o planeta está a caminho de um aquecimento global equivalente ou superior a 4 graus Celsius. Se as nações cumprirem as metas que apresentaram na Conferência do Clima em Paris, no fim do ano passado, o aumento da temperatura global chegará a 3 graus Celsius.

As mudanças climáticas devem ser encaradas com preocupação para setores e investidores que exercem a atividade pensando a longo prazo, como os fundos de pensão e reguladores financeiros.

Diretor do programa de finanças sustentáveis da Universidade de Oxford, no Reino Unido, Ben Caldecott ressalta que os impactos financeiros das mudanças climáticas são um risco de grande escala.

— Os investidores podem fazer muito para diferenciar entre as empresas mais ou menos expostas e, assim, conseguirem ajudar a reduzir os riscos para a economia global, apoiando ações ambientais sobre as mudanças climáticas.

MAIS GRAVE QUE POLIOMIELITE

Ontem, um relatório divulgado na Casa Branca alertou que as mudanças climáticas representam uma grave ameaça para a saúde pública — em muitos aspectos, pior do que a poliomielite — e atacará especialmente gestantes, crianças, pessoas de baixa renda, negros, asiáticos e hispânicos.

O documento “Os impactos das mudanças climáticas na saúde humana nos EUA: uma avaliação científica”, adverte sobre os riscos arrebatadores para a saúde pública do aumento da temperatura nas próximas décadas, que também levaria a mais mortes e doenças por insolação, insuficiência respiratória e doenças como o vírus do Nilo Ocidental.

Aumento do nível do mar ameaça inundar estação da Nasa (O Globo)

05/04/2016, por O Globo

Lançamento de foguete em Cano Canaveral: centro tecnológico é vulnerável a aumento do nível do mar– John Raoux/AP/18-11-2013

RIO — Um dos maiores e mais sofisticados centros de tecnologia do mundo, a base de lançamento de foguetes da Nasa em Cabo Canaveral, na Flórida, corre risco de ser inundada. O aumento do nível do mar, em consequência das mudanças climáticas, ameaça a infraestrutura da agência espacial ao longo da costa de 115 km. Os riscos já levaram a agência espacial americana a estudar a remoção das instalações.

Em todo o país, cerca de dois terços das instalações da Nasa estão em regiões de altitude inferior a 4,8 metros, e a maior parte se localiza em zonas costeiras, onde as agitadas correntes oceânicas já contribuem para a erosão dos equipamentos.

— Estamos tremendamente ligados à água — alerta Kim Toufectis, estrategista da agência espacial americana.

De acordo com um estudo publicado semana passada na revista “Nature”, o aquecimento global pode aumentar o nível do mar entre 1,5 metro e 1,8 metro até o fim do século. Um grupo de trabalho da Nasa estima que o aumento do nível do mar de 12 centímetros para mais de 60 centímetros até 2050 pode levar a problemas em cinco estações costeiras da agência:

“Os centros da Nasa que já estão sob risco de inundação devem se tornar mais vulneráveis no futuro”, previa o grupo em um relatório em 2014.

Com a ameaça do clima, a Nasa tem como alternativa a instalação de barreiras e outras estruturas que contenham o aumento do nível do mar e os efeitos de tempestades e inundações. Em locais onde a adaptação não for possível, uma alternativa será o “recuo estratégico” — uma medida bem mais cara, na casa dos bilhões de dólares.

Além de exigir muito dinheiro, a remoção das instalações envolve a construção de edifícios, traslado de equipamentos e deslocamento de equipes, e por isso ainda deve demorar.

Enough about Ethnography: An Interview with Tim Infold (Cultural Anthropology)

April 5, 2016

by Susan MacDougall

The Summer 2014 issue of HAU: Journal of Ethnographic Theory included the article “That’s Enough about Ethnography!”, by Tim Ingold, who is Chair in Social Anthropology at the University of Aberdeen. What follows is a lightly edited transcript of an interview that contributing editor Susan MacDougall conducted with Ingold about the article and reactions to it.

Susan MacDougall: In your HAU article, you identify the need for anthropology to “heal the rupture between imagination and everyday life.” When you talk about this rupture, you link it to a divorce of fact from theory. Can you expand on this notion and why it is important for the future of anthropology? 

Timothy Ingold: The problem here lies in the degree to which anthropology, as an academic discipline, remains compliant with the protocols of normal science. These protocols enforce a division between the real world, from which we are expected to gather “data,” and the world of theory, in which these data are to be interpreted and fashioned into authorized knowledge. This division is only reinforced by continual appeals to the idea of anthropological knowledge production. It is as though we go to the world for our material, but then turn our backs on it in working this material into the finely crafted, peer-reviewed artifacts that we recognize as books and articles. To my mind, this procedure fatally compromises the core mission of anthropology, which is to demonstrate—by precept and example—how to do our thinking in and with the world we inhabit: in response to its summons, rather than after the fact. This means giving due recognition to what we know full well from our inquiries, namely that what is given to us is not just there for the taking as data for collection, but is an offering, the acceptance of which carries a responsibility of care. Anthropology shows that curiosity and care, pried apart in mainstream science policy by a spurious and ethically indefensible division between research and impact, are inseparable aspects of our relations with those to whom we owe our education in the ways of the world.

SM: Timothy Jenkins (1994) referred to fieldwork as a series of apprenticeships, and pointed out that learning how to get along in the field involves quite a bit of un-learning one’s own assumptions. You also mention Kenelm Burridge’s metanoia: an ongoing series of transformations that alter the predicates of being. These are possible results of encounters, ethnographic or otherwise, and if those results lead to fruitful analysis, all the better. If this is such a commonplace thing to do, though, how can the aspiring anthropologist prepare to do it and do it well?

TI: Certainly, there is an element of unlearning in all fieldwork. What would be the point of it otherwise? Such unlearning, moreover, can be unsettling and does involve an element of existential risk. My point, however, is that unlearning is intrinsic to education, understood in its original sense as a leading out into the world that frees us from the limitations of standpoints or perspectives and causes us continually to question what previously we would have taken for granted. This is what we expect from our students in the classroom, as much as what we expect from ourselves in the field.

Two things follow from this. First, although only a tiny proportion of the students we teach—at least at introductory levels—will go on to become practicing anthropologists, our task is nevertheless to foster an anthropological attitude that all of them may take into whatever walks of life they subsequently follow. Preparation for anthropology is preparation for life, and it lies in the cultivation of a readiness to both listen to others and question ourselves. Second, whether this preparation and the results that flow therefrom yield to “fruitful analysis,” as you put it, depends on what we mean by analysis. If we mean the processing and interpretation of empirical data in the normal scientific sense, then the answer is no. But if analysis means a critical interrogation that opens simultaneously to the self and to the world, then the answer is a definite yes!

SM: Conversely, is it possible to do the encounter badly or incorrectly? Or do weaknesses and mistakes emerge later, in the note-taking and what follows? If anthropologists would like to maintain some claim to ethnography or to participant-observation, then is there a need to distinguish between the high- and low-quality conduct of both?

TI: The opposite of opening is, of course, closure. That is when we refuse to attend to the presence of others or to what they have to offer. I suppose a “bad” encounter would be one in which we see but do not observe, hear but do not listen, touch but do not feel. In such an encounter, we would pick up signals as data, but remain impervious to them. Our curiosity would be divorced from care. This, of course, is what is generally recommended by science in the name of objectivity. But as I have stressed, objectivity is one thing, observation quite another. Observers are bound to make mistakes, and our field notes are doubtless full of them. We can misunderstand what people say, jump to the wrong conclusions, or confuse one thing for another. There’s nothing intrinsically wrong with that: as in any situation of apprenticeship, we learn from our mistakes. But no amount of correction can make up for a failure to attend. Even if, objectively speaking, there were to be not a single error in our data, we could still fail to draw any lessons from them. We learn much from mistakes of observation grounded in attention, and nothing whatsoever from an objectively “correct” record that is nevertheless grounded in inattention.

SM: You point out in the article that anthropologists’ obsession with ethnography has a navel-gazing quality, turning “the project of anthropology into the study of its own ways of working.” Certainly anthropologists can be sentimental about their fieldwork experience and consider it formative for their characters as well as their scholarship. But, as you point out, this willingness to be changed by the fieldwork experience is what makes it an education as opposed to straightforward data collection. Do you see a way for this admission—that is, that participant observation can be personally transformative—to enhance anthropology’s impact in the world, rather than undermining it? 

TI: This is precisely why anthropology can potentially make such a difference in the world. But we should not have grudgingly to “admit” that fieldwork can personally transform the observer, as though we were offering an apology for anthropology’s inability to come up with accounts that more positivist disciplines would regard (in their terms) as suitably robust or evidence-based. Nor should our addiction to fieldwork be used to justify disciplinary introversion, affording an excuse to retreat into our own shells and to talk only to ourselves about the conditions and possibilities of anthropological knowledge production. On the contrary, we should be leading a campaign against the very idea that the world presents itself to human science as a standing reserve of data for collection. And to do this, we must stop pretending to believe in this idea ourselves.

For this reason I insist that participant-observation is not a research method but, more fundamentally, an ontological commitment: an acknowledgement of our debt to the world for what we are and what we know. This is a commitment, I believe, that should underwrite not just anthropology but every branch of scientific inquiry. Whatever our field of specialization, we should have the humility to recognize that understanding can only grow from within the world we seek to know, the world of which we are a part. This recognition, however, strikes at the core of the constitution of the academy. It is why anthropology’s campaign must also be a campaign for the heart and soul of the academy. The stakes could scarcely be higher.

SM: In a related vein, I’d like to bring up Amy Pollard’s (2009) piece “Field of Screams,” which took anthropology to task for sending vulnerable students off into the field to meet with traumatic and isolating experiences. It seems that a direct, convincing definition of ethnography will remain elusive if postfield graduate students are afraid to talk about what they actually did in the field. Do you see a way for anthropology to address the sometimes painful realities of fieldwork, without undue reliance on procedures that look like they were written by university risk management offices and not anthropologists? 

TI: Traumatic and isolating experiences are not exclusive to anthropological fieldwork. They are a part of life. In life in general, as in fieldwork in particular, painful realities are always hard to talk about. The absurdity of bureaucratic risk management, on which so many of our universities nowadays insist, is that they fail to understand this. Were we to follow their logic to the letter, then we would have a society in which no baby could be born without a divinely ordained risk management schedule that would anticipate every contingency of its future life. That institutions should have usurped such godlike powers for themselves—in the interests, it must be said, not of protecting their researchers but of protecting themselves against litigation should things go wrong—is an indication of the corporate dishonesty that now pervades the higher education sector. Anthropology should not participate in this dishonesty. I do not think, however, that this issue of risk management has any immediate bearing on the definition of ethnography, unless of course we were to include within our catalog of risks the isolations and traumas of writing up. As I have endeavored to show, ethnography and participant-observation are not the same, and their common identification has brought nothing but confusion.

SM: One of the reasons I was interested in discussing this article with you is that it clearly sparked a conversation. Rarely do journal articles show up in my Twitter feed or inspire threads on the Open Anthropology Cooperative, and this one certainly did. Have you had any particularly thought-provoking responses to this article? Have any of them prompted you to reevaluate your views?

TI: There is no doubt that my article touched a raw nerve in the discipline. It seems to have brought into the open a number of issues that have long been simmering beneath the surface, and that many would have preferred to have kept there. The responses I have received are roughly of two kinds. The first are supportive. They come principally from younger scholars who thank me for stating explicitly what they have long felt, but have been afraid to express for fear of rocking the boat. The second come from critics who accuse me of tilting against windmills. They complain that, in distinguishing ethnography from anthropology, I have resorted to a narrow, old-fashioned, and overly literal characterization of ethnography that bears little resemblance to what most scholars who would call themselves ethnographers actually do nowadays. Looking at the content of most mainstream anthropological journals, I am a little skeptical of this complaint.

Be that as it may, my response is that even if so-called ethnographers are already doing everything that I am calling for under the banner of anthropology, ethnography is nevertheless a singularly inappropriate term by which to describe it. Maybe among ourselves, with our common experience of having undertaken fieldwork of one kind or another, we can share an in-house understanding of what ethnography means without having to spell it out too precisely. This understanding, however, does not extend to realms beyond the bounds of the discipline, where fundamental misapprehensions remain about what anthropologists do and why it is important. Overuse of the term ethnography, I believe, only feeds these misapprehensions and makes it more difficult, not less, to explain what we do and what its value might be to others: whether they are students, academics in other disciplines, or the public at large. Anthropology is a noble calling and not one to be ashamed of. Why should we hide it under another term, ethnography, as if pretending to do something completely different?

Within a historical context, ethnography attempts to be holistic in nature based in part on emic views. It is written, observational science that provides an account of a particular culture, community or society. Typically, it involves fieldwork or spending a year or more in another society, living among its people, and trying to understand them as much as possible. Further, it is a meeting ground for many disciplines that focus on human and social sciences. Principle among these are sociology, economics, education, religious studies, geography, history, linguistics, psychology and political science.
