Gregorio Duvivier explica a “positividade tóxica” do atual governo e de personalidades famosas nas redes sociais. Ele cita TikTokers, a Fundação Cacique Cobra Coral e “aquilo que faz com que o governo acredite que ele vai contornar a crise hídrica apenas com a força do pensamento”.

“É aquela positividade que consiste em simplesmente ignorar as coisas negativas, controlar qualquer pensamento pessimista e fingir que a vida não tem problema”, explica. Para o humorista, isso nos faz “ter versão mais infantil das situações” e “perder a capacidade de encarar momentos difíceis”.

“Positividade tóxica é grande aliada do capitalismo”, diz Duvivier

A escala do problema, avalia Duvivier, atinge toda a sociedade. “Positividade tóxica é uma grande aliada do capitalismo ao estimular responsabilização individual pelas injustiças que o próprio sistema capitalista gera”, critica. Para Gregorio, “essa lógica de acreditar que a gente pode ter tudo o que quiser se tiver pensamento positivo é justamente o que sustenta uma economia de mercado”.

“Tem um outro terreno no qual a positividade tóxica pode ser uma arma muito poderosa, a ponto dela se tornar perversa. É aa política. Sim, é no âmbito da política que a positividade tóxica vira um instrumento de controle social e manter as pessoas num estado de imobilidade”, prossegue Duvivier. Ele cita que o instrumento é usado para cessar a indignação da sociedade, que gera protestos e afins.

Organization Sends Warning Ahead of COP26 (The Maritime Executive)

As the world gathers in Glasgow, Scotland for the next United Nations climate change conference (COP26), the UN’s World Meteorological Organization (WMO) has warned the world is “way off track” in slowing down GHG emissions.  

This is because the abundance of heat-trapping GHG in the atmosphere once again reached a new record last year, with the annual rate of increase above the 2011-2020 average. Notably, the economic slowdown from COVID-19 did not have any discernible impact on the atmospheric levels of GHG emissions and their growth rates, although there was a temporary decline in new emissions.

WMO GHG Bulletin shows that concentration of carbon dioxide (CO2), the most important GHG, reached 413.2 parts per million in 2020 – nearly 150 percent of the pre-industrial level. The last time the Earth experienced a comparable concentration of CO2 was 3-5 million years ago, when the temperature was 2-3°C warmer and sea level was 30-60 feet higher than today. 

The concentration of methane (CH4) – a far more powerful greenhouse gas – has reached 262 percent of the levels seen in 1750, when human industry started disrupting Earth’s natural equilibrium. 

“The GHG Bulletin contains a stark, scientific message for climate change negotiators at COP26. At the current rate of increase in GHG concentrations, we will see a temperature increase by the end of this century far in excess of the Paris Agreement targets of 1.5 to 2 degrees Celsius above pre-industrial levels,” said Prof. Petteri Taalas, WMO Secretary General.

This cautionary message comes as world leaders, civil society and media are set to assemble in Glasgow, Scotland to discuss progress on the Paris Agreement and the UN Framework Convention on Climate Change. Concerns over rising temperatures have prompted many countries to set detailed timetables for decarbonization, and it is hoped that COP26 will see an increase in commitments. 

WMO notes that as long as emissions continue, global temperature will continue to rise. In fact, given the long life of CO2, the temperature level already observed will persist even if emissions are rapidly reduced to net zero. Alongside rising temperatures, this means more weather extremes, including intense heat and rainfall, ice melt, sea-level rise and ocean acidification, accompanied by far-reaching socioeconomic impacts.

Roughly half of the CO2 emitted by human activities today remains in the atmosphere with the other half taken up by oceans and land ecosystems. Concerns are mounting that the ability of land ecosystems and oceans to act as “sinks” may become less effective in the future, thus reducing their ability to absorb CO2 and act as a buffer against larger temperature increases.

Machine learning can be fair and accurate (Science Daily)

Date: October 20, 2021

Summary: Researchers are challenging a long-held assumption that there is a trade-off between accuracy and fairness when using machine learning to make public policy decisions.


Carnegie Mellon University researchers are challenging a long-held assumption that there is a trade-off between accuracy and fairness when using machine learning to make public policy decisions.

As the use of machine learning has increased in areas such as criminal justice, hiring, health care delivery and social service interventions, concerns have grown over whether such applications introduce new or amplify existing inequities, especially among racial minorities and people with economic disadvantages. To guard against this bias, adjustments are made to the data, labels, model training, scoring systems and other aspects of the machine learning system. The underlying theoretical assumption is that these adjustments make the system less accurate.

A CMU team aims to dispel that assumption in a new study, recently published in Nature Machine Intelligence. Rayid Ghani, a professor in the School of Computer Science’s Machine Learning Department (MLD) and the Heinz College of Information Systems and Public Policy; Kit Rodolfa, a research scientist in MLD; and Hemank Lamba, a post-doctoral researcher in SCS, tested that assumption in real-world applications and found the trade-off was negligible in practice across a range of policy domains.

“You actually can get both. You don’t have to sacrifice accuracy to build systems that are fair and equitable,” Ghani said. “But it does require you to deliberately design systems to be fair and equitable. Off-the-shelf systems won’t work.”

Ghani and Rodolfa focused on situations where in-demand resources are limited, and machine learning systems are used to help allocate those resources. The researchers looked at systems in four areas: prioritizing limited mental health care outreach based on a person’s risk of returning to jail to reduce reincarceration; predicting serious safety violations to better deploy a city’s limited housing inspectors; modeling the risk of students not graduating from high school in time to identify those most in need of additional support; and helping teachers reach crowdfunding goals for classroom needs.

In each context, the researchers found that models optimized for accuracy — standard practice for machine learning — could effectively predict the outcomes of interest but exhibited considerable disparities in recommendations for interventions. However, when the researchers applied adjustments to the outputs of the models that targeted improving their fairness, they discovered that disparities based on race, age or income — depending on the situation — could be removed without a loss of accuracy.

Ghani and Rodolfa hope this research will start to change the minds of fellow researchers and policymakers as they consider the use of machine learning in decision making.

“We want the artificial intelligence, computer science and machine learning communities to stop accepting this assumption of a trade-off between accuracy and fairness and to start intentionally designing systems that maximize both,” Rodolfa said. “We hope policymakers will embrace machine learning as a tool in their decision making to help them achieve equitable outcomes.”

‘O movimento antivacina é também um efeito da hiperinformação’ (Nexo)

Entrevista

João Paulo Charleaux – 13 de out de 2021 (atualizado 13/10/2021 às 00h26)

Laurent-Henri Vignaud, historiador da ciência na Universidade de Bourgogne, fala ao ‘Nexo’ sobre as ideias, à direita e à esquerda, por trás do movimento antivacina nos últimos 300 anos

A resistência à vacinação é um fenômeno antigo e persistente, que encontra adeptos à esquerda e à direita – sempre nas franjas mais extremas desses setores –, e não está ligado à falta de educação, mas ao excesso de informação e à dificuldade de saber em que acreditar, de acordo com o historiador da ciência Laurent-Henri Vignaud, da Universidade de Bourgogne, na França.

O autor do livro “Antivax: Resistência às vacinas, do século 18 aos Nossos Dias” esmiuça, nesta entrevista concedida por escrito ao Nexo nesta quarta-feira (6), os argumentos dos que ainda resistem a se vacinar contra a covid-19 em todo mundo, e faz um retrospecto desse movimento antivacinal ao longo da história.

Vignaud fará uma conferência virtual sobre o tema no dia 14 de outubro, no ciclo de palestras sobre a Covid promovido pelo Consulado da França em São Paulo em parceria com a Unesco, órgão das Nações Unidas para educação e cultura, e com os Blogs de Ciência da Unicamp. A transmissão é ao vivo e os vídeos ficam disponíveis nos canais do Consulado da França na internet.

Quais são os argumentos daqueles que se opõem à vacinação? Como esses argumentos variaram nos últimos 300 anos?

Laurent-Henri Vignaud Esses argumentos são muito diversos, assim como os perfis “antivax”. Muitos têm dúvidas simples sobre a qualidade das vacinas ou sobre os conflitos de interesse de quem as promove. Outros desenvolvem teorias extremas de conspiração, dizendo que as vacinas são feitas para adoecer, para esterilizar, matar ou escravizar. No meio, há aqueles que “hesitam” por tal ou tal motivo.

Aqueles que recusam explicitamente uma ou mais vacinas – quando falamos estritamente dos “antivax” – o fazem por motivos religiosos, políticos ou alternativos e naturalistas. Há certas correntes rigorosas, em todas as religiões, que recusam a vacinação em nome de um princípio fatalista e providencialista, numa afirmação da ideia de que o homem não é senhor de seu próprio destino.

Já os que se opõem às vacinas por razões políticas atacam as leis impositivas em nome da livre disposição de seus corpos e das liberdades individuais, no discurso do “meu corpo me pertence”.

Outros, muito numerosos hoje, contestam a eficácia das vacinas e defendem outras terapias que vão desde regimes de saúde a fitoterápicos e homeopatia – o que aparece em discursos como “a imunidade natural é superior à imunidade a vacinas” e “as doenças nos fortalecem”. A maioria desses argumentos está presente desde o início da polêmica vacinal no final do século 18, mas se atualizam de maneira diferente em cada época.

Historicamente, o movimento antivacinação é de direita ou de esquerda? Isso é algo que mudou ao longo do tempo ou permanece o mesmo?

Laurent-Henri Vignaud Atualmente, as duas tendências existem: há uma postura “ecológica” antivacina que é bastante esquerdista e burguesa – um modelo muito difundido por exemplo na Califórnia entre funcionários de empresas digitais. E há uma postura “libertária” ou “confessional” antivacina, que é de direita, presente sobretudo na América, em círculos religiosos conservadores e partidários de líderes populistas como [o ex-presidente dos EUA Donald] Trump ou [o presidente do Brasil, Jair] Bolsonaro.

Historicamente, a inoculação, técnica que antecedeu as vacinas no século 18, foi promovida por filósofos como Voltaire [iluminista francês, 1694-1778] e contrariada por homens da Igreja. Portanto, podemos classificar essa oposição como uma oposição à direita. No século 19, a dureza das medidas de vacinação obrigatória levou à revolta de setores mais pobres que não podiam escapar da injeção. O vacinismo aparece aí como higiene social e o antivacinismo, como algo protagonizado por movimentos operários, feministas e de defesa dos animais, mais marcadamente à esquerda, portanto.

A Revolta da Vacina, de 1904, no Brasil, foi desencadeada por uma campanha de vacinação forçada pretendida pela jovem República, que gerou motins na classe trabalhadora. No século 20, o antivacinismo está representado à direita e à esquerda, mas quase sempre nos extremos.

O que explica por que a França, país desenvolvido, rico, cientificamente avançado, onde não faltam fontes confiáveis de informação, tenha hoje uma resistência tão elevada à vacinação, mesmo entre os profissionais de saúde?

Laurent-Henri Vignaud Esse é um fenômeno recente. A França não está isenta da tradição antivacinal. Na verdade, essa era uma tradição até bastante virulenta na época de Pasteur [século 19], a ponto de atrasar o estabelecimento de uma obrigação de vacinar contra a varíola, mas esta não é uma opinião muito difundida até o início do anos 2000.

Por exemplo, nossa primeira liga “antivax” apareceu em 1954 após a entrada em vigor da obrigação do BCG, mas, à época, os ingleses e os americanos já tinha ligas “antivax” há quase um século.

Durante a última epidemia de varíola na Bretanha em 1954-1955, na altura em que o prefeito decretou o reforço da vacinação obrigatória, mais de 90% dos habitantes concernidos já tinham sido vacinados voluntariamente.

Essa confiança foi abalada durante o debate sobre a vacina contra a hepatite B em meados da década de 1990, até porque os políticos se contradiziam sobre sua possível periculosidade. E, na crise do do influenza A em 2009, a campanha de vacinação falhou. Os franceses não acreditavam na possibilidade de uma pandemia e não entendiam por que deveriam ter sido vacinados contra uma doença na qual não viam perigo. Talvez o choque da pandemia de covid reverta essa tendência.

Como você explica o fato de que os boatos, o misticismo e a irracionalidade persistam, mesmo em uma época em que a ciência se desenvolveu tanto, mesmo em uma época em que a educação formal alcançou tantos? Essa adesão às teorias da conspiração seria uma característica humana inextinguível?

Laurent-Henri Vignaud A suspeita de riscos tecnológicos – porque a vacina é um produto manufaturado – não se alimenta da falta de informação, mas de seu transbordamento. É por sermos inundados com informações e por não podermos lidar com um décimo delas que nós duvidamos.

Quem de nós pode explicar, ainda que de forma grosseira, como funciona algo tão difundido como um telefone celular? Diante dessa superabundância de quebra-cabeças técnico-científicos e de conhecimentos que não podemos assimilar, os cidadãos 2.0 fazem seu mercado e acreditam no que querem acreditar de acordo com o que consideram ser do seu interesse.

A maioria confia em palavras de autoridade e no pouco que conseguem entender de tudo o que chega a si. Alguns ficam insatisfeitos com as respostas que lhes são dadas e passam a duvidar de tudo, chegando a imaginar universos paralelos e paranóicos. Não é, portanto, na ignorância que estas crenças se baseiam, mas sim num “ônus da prova”, que pesa cada vez mais sobre os ombros dos cidadãos contemporâneos.

Nessa “sociedade de risco”, os cidadãos contemporâneos são cada vez mais instados a assumir a responsabilidade por si próprios e julgar por si próprios o que é verdadeiro e o que é falso. Em alguns, o espírito crítico se empolga e leva a uma forma de ceticismo radical da qual o antivacinismo é um bom exemplo.

Mudanças climáticas desafiam modelo atual de grandes monoculturas (Folha de S.Paulo)

NÁDIA PONTES – 22 de outubro de 2021

SÃO JOSÉ DOS CAMPOS, SP (FOLHAPRESS) – Entre os 364 produtores do assentamento Santo Angelo, Ivo Bernardo da Silva está ilhado. Dono de um sítio em Mogi das Cruzes, cinturão verde que abastece a maior cidade da América Latina, São Paulo, ele diz ser o único que cultiva alimentos sem agrotóxicos.

São 37 variedades, incluindo hortaliças e condimentos, que crescem em quatro mil metros quadrados cuidados por Silva, 67, e a namorada. Só dos vários tipos de alface, eles colhem 18 mil pés por ano.

“A gente cuida da natureza e ela devolve assim, com comida de qualidade”, afirma.

Recursos usados no cultivo vêm do próprio sítio: a água da chuva armazenada ou do poço artesiano irriga as plantas; o adubo é resultado da compostagem, feita ali mesmo.

A rotina de trabalho é um meio de oferecer à população acesso a alimentos saudáveis, cultivados de forma sustentável, diz Silva. “Acredito nos pequenos, na agricultura familiar”, afirma o produtor, que vende o que colhe diretamente aos consumidores.

O modo adotado por Silva é um dos caminhos apontados pela ciência para garantir segurança alimentar num mundo que precisa passar por uma transição rápida de modelo.

“As mudanças climáticas estão ocorrendo. A grande agricultura de impacto ambiental muito forte precisa mudar. Todo mundo já entendeu isso, de consumidores a produtores”, diz Gustavo Chianca, representante no Brasil da FAO (Organização das Nações Unidas para a Alimentação e Agricultura).

O custo real desse impacto para a saúde do planeta e de seus habitantes quase não aparece nos preços finais dos alimentos. É o que mostra um projeto das universidades de Greifswald e Augsburg, na Alemanha, em conjunto com uma rede de supermercados.

Ao calcularem custos ecológicos e sociais de vários alimentos, os pesquisadores constataram grande diferença entre os preços nas gôndolas e os valores reais.

“Os produtos de origem animal têm um desempenho particularmente ruim”, dizem os cientistas. A carne moída, por exemplo, teria que custar o triplo se fossem consideradas emissões de gases de efeito estufa, mudanças no uso do solo e consumo de energia no processo de produção. Já os alimentos orgânicos de origem vegetal são os que têm preços mais “reais”, por respeitarem mais o ambiente.

“Uma internalização desses custos resultaria na correção dos preços de mercado, e o comportamento de compra seria ajustado de acordo com a sustentabilidade”, escreveu sobre os resultados a pesquisadora Amelie Michalke.

Independentemente do tamanho da propriedade ou da cadeia produtiva, fatores urgentes precisam entrar em definitivo para a equação, alerta Leandro Giatti, pesquisador que integra a recém-criada Cátedra Josué de Castro de Sistemas Alimentares Saudáveis e Sustentáveis, da Faculdade de Saúde Pública da USP (Universidade de São Paulo).

“A produção de alimentos é avaliada pela produtividade e o lucro. Não dá mais para fazer isso. É preciso fazer o balanço da disponibilidade de energia, e o custo que essa energia vai gerar em outras regiões. O mesmo vale para a água”, diz Giatti.

Com o padrão vigente, não seria possível oferecer alimentos a uma população crescente e cuidar do meio ambiente ao mesmo tempo, avalia Manuela Santos, pesquisadora da FGV (Fundação Getúlio Vargas).

“Esse modelo de cultivo em larga escala, de monocultura, altamente dependente de insumos de fora da propriedade, não é a resposta que precisamos”, diz.

Uma alternativa seria o incentivo a produções sustentáveis em pequena escala que, organizadas em cooperativas, conseguem abastecer grandes mercados, sugere Santos.

“As cadeias de abastecimento são longas, os pequenos produtores ficam à margem. Se não se organizam, se não têm capacidade de chegar ao consumidor final, fica mais difícil”, afirma Santos, ressaltando que mais transparência nesse processo traria um grande impacto positivo.

Pelos critérios definidos por lei, são produtores familiares os que têm até quatro módulos fiscais (medida de área que sofre variação conforme o município), usam mão de obra da família e têm renda vinculada ao estabelecimento.

A agricultura familiar corresponde a 77% das propriedades rurais do país, mas ocupa 23% da área total de estabelecimentos contabilizados no último Censo Agropecuário. Ela produz parte considerável do que vai para a mesa brasileira, como leite, mandioca, abacaxi, alface, feijão.

“A agricultura familiar garante muitas vezes o alimento que é consumido no dia a dia da população, mas também está envolvida no agronegócio exportador. É ligada à diversidade de alimentos, tem a tendência de ser mais sustentável, mas é preciso aprofundar, também na agricultura familiar, o conceito de produzir e de preservar”, argumenta Chianca.

Essa é a missão de Veridiana Vieira, da Repoama, Rede de Produção Orgânica da Amazônia Mato-Grossense.

Em sua tentativa de ampliar os agricultores adeptos dessa prática, ela encontra resistência. “A primeira coisa que ouvimos é que eles não vão conseguir produzir sem veneno. Nosso trabalho é mostrar que é possível, e mais vantajoso”.

O primeiro benefício, explica Veridiana Vieira, é a economia de insumos agrícolas. O grupo troca sementes, esterco e experiências. E faz compras coletivas, o que deixa tudo mais barato.

“São muitos benefícios, mas o principal é a preservação. Ao não usar agrotóxico, você melhora a qualidade da água, do solo, atrai mais polinizadores”, acrescenta.

“Existem outras coisas que não dá pra contar em dinheiro, como o aumento do bem-estar, da saúde, a redução de alergias nas crianças”, cita ela, resumindo experiências contadas por integrantes da rede.

Quando brasileiras brancas descobrem na Europa que, com a brancura, não podem mobilizar privilégios (Geledés)

geledes.org.br

Por Fabiane Albuquerque, enviado ao Portal Geledés

24/10/2021


Moro na França há alguns anos. Também já morei na Itália e, além dos meus estudos sobre branquitude, convivo com brasileiras no exterior e tenho uma vasta experiência com as frustrações, queixas e crises de mulheres brancas, sobretudo das classes médias e altas. Eu observo pessoas brancas há muito tempo. Acho que comecei a refletir sobre elas ouvindo as histórias das mulheres da minha família que trabalhavam nas suas cozinhas, fazendas, em estreita relação com a branquitude brasileira. Então, não me faltaram relatos sobre como se comportavam, pensavam, diziam e se relacionavam, sobretudo com os seus iguais e o seu Outro (negros e negras). 

Essas mulheres, contudo, não nos viam (e ainda não nos veem) porque estão ocupadas demais em projetar em corpos negros as coisas mal resolvidas em si mesmas. Incrível como falam da pobreza no Brasil, dos problemas políticos e sociais, da falta de educação do povo brasileiro, sem ao menos se darem conta dos problemas dentro de seus lares. Lourenço Cardoso escreve sobre isso na sua tese de doutorado intitulada: “O branco ante a rebeldia do desejo: um estudo sobre a branquitude no Brasil” e explica que negros, mesmo sendo desumanizados por brancos, ainda conseguem vê-los enquanto humanos; já o contrário é difícil. 

Pois bem, vejo estas mulheres que, acostumadas a projetar o olhar para fora, para o outro, raramente se questionam e se veem como de fato são. Não se enxergam brancas, privilegiadas, construídas e projetadas como seres superiores com base na raça e no pertencimento de classe no Brasil. E, quando chegam na Europa e descobrem que, por serem brancas e possuírem dinheiro, não podem tirar proveito da situação como fazem no país que as endeusou, entram em crise.  A crise dessas mulheres é uma das coisas mais interessantes que meu olhar de pesquisadora pôde ver.  Essa não é consciente para elas, assim como não é o fato de que a brancura lhes garantiu um lugar confortável na sociedade de origem. 

Por três anos meu filho estudou na mesma classe que o filho de uma brasileira branca, loira, de Santa Catarina, advogada e apoiadora de Bolsonaro, antipetista, antilulista e possuidora de uma visão estereotipada sobre a esquerda, os negros e os pobres. Mas, uma coisa aqui mudou na vida dela: embora nós duas tenhamos origem social e raça diferentes, a França nos nivelou. Eu e ela moramos no mesmo bairro e nossos filhos frequentaram a mesma escola, diga-se de passagem, pública. Para ela, mais do que para mim, isso constituiu um grande incômodo, manifesto na sua tentativa constante de mostrar-me o que ela tinha de diferencial em relação à mim. 

Como a questão financeira não era o principal mobilizador de superioridade, tampouco ela possuía conhecimentos sobre cultura, ou seja, enquanto eu sou amante de livros, pesquisadora, escritora, conheço de literatura brasileira, francesa, italiana, dentre outras, vou ao teatro e cinema, ela se orgulhava de ser frequentadora assídua de academia, Disneylândia e Mcdonalds. No Brasil, parece que a futilidade dessas pessoas é ofuscada pelo privilégio de raça e de classe.

Certo dia, na porta da escola, ela me abordou da seguinte forma: 

-Ai guria, tem dias aqui que é difícil, estou para ficar louca. Outro dia fui ao banco sozinha e me trataram como uma qualquer, você acredita?

Incrédula com a expressão, pois esse “ser qualquer um” deveria ser o sentimento de todo cidadão, de juiz a gari, de professor à médico, de político à banqueiro, balancei a cabeça dando-lhe corda: 

-Verdade? 

E ela continuou:

-Eu tive que ligar para o meu marido ir até lá para ver se com ele seria diferente. Ele vive recebendo propostas para investimento do banco porque ganha bem.

Fiquei pensando nas suas palavras. Aqui na França, ela não pode mobilizar um tratamento diferenciado por ser loira e muito menos pela sua classe social. Aqui o “você sabe com quem está falando?” não cola como no Brasil. Afinal, ela é só mais uma branca dentre brancos. E os brancos daqui, como diz o pesquisador Lourenço Cardoso, são “mais brancos” que os nossos brancos devido a impressão digital deixada pela colonização que hierarquizou povos e nações. Quanto mais nórdico, como os ingleses, mais branco e ideal é um povo.

Como eu jamais a bajulei por ser branca (como geralmente acontece entre brasileiros), outra vez, na porta da escola, ela me abordou novamente. Eu disse que estava indo caminhar e ela logo se oferece para ir junto. No caminho, sem nenhum pudor, me solta essa:

-Quando meu filho nasceu, a preocupação do meu marido era com o cabelo, se ia nascer ruim como o dele. Eu até achei engraçado porque assim que ele nasceu, ele correu para mim e disse “parece que é ruim, é bem enrolado”. 

Eu, que tenho cabelo “ruim” na concepção da sua família somente soltei um “é mesmo?” e parece que aquilo liberou nela seu racismo mais latente. Esse só sai quando a pessoa não se sente julgada ou rechaçada, quando acha abertura e acredita que o interlocutor não a está julgando:

-Meu marido (branco no Brasil) ‘rapa’ a cabeça porque ele odeia o próprio cabelo. Mas quando viu que puxou a mim ficou mais tranquilo. 

O que essa mulher queria ao me dizer tudo isso? Ela estava buscando que eu reconhecesse a sua superioridade, pelo menos aquela racial, já que eu, por espontânea vontade não o fiz, ela estava ali me lembrando disso. A igualdade é um dos maiores sofrimentos psíquicos para mulheres brancas brasileiras das camadas altas que chegam para morar aqui na Europa. Digo de mulheres porque convivo pouco com os homens brancos brasileiros. E não parou aqui, não. Outra vez ela fez o seguinte comentário:

-Guria, falei com minha prima que mora na Inglaterra e ela me disse que sou louca de colocar meu filho em escola pública, de me misturar com esta gente

Ela se referia à grande presença de crianças imigrantes na escola, de origem africana e de países árabes. A escola pública foi o espaço que acolheu o seu filho, o ensinou a falar francês, lhe proporcionou uma base e uma convivência respeitosa e igualitária com diferentes nacionalidades, sobretudo aquelas as quais ele nunca teve contato no Brasil por viver segregado no seu pequeno mundinho burguês.  Mas, ela insistia em tentar se colocar como um ser especial. 

Antes que alguém diga que tive muita paciência, só resisti porque estudo brancos e quando descobri que é melhor lhes dar corda para ter material, meu envolvimento afetivo e emocional me causa menos sofrimento.  

O estupor por não ser tratada com distinção não vem somente de gente de extrema direita. Nesse ponto, a branquitude se assemelha muito, tanto de direita quanto de esquerda. Uma moça branca, paulistana e segundo ela mesma, de classe média alta, revelou-me que estava surpresa por sofrer discriminação dentro da universidade francesa. A pergunta que ela me fez foi a seguinte:

– Eu posso me comparar com os negros por sofrer racismo

Lhe respondi que com negros, jamais. E continuei dizendo que aqui, antes de tudo, ela é brasileira e tinha alguns traços árabes como o nariz e o formado do rosto. Ela estava desorientada por não poder usufruir da “invisibilidade” da raça como acontecia no Brasil e talvez, sem se dar conta, da visibilidade por ser branca e burguesa na hora de receber privilégios. Essas mulheres estão acostumadas, desde pequenas, a serem paparicadas e, quando isso não acontece, o Eu se fragiliza. 

Uma outra, branca de olhos verdes, vendo que eu jamais comentei algo sobre a sua aparência física, como está acostumada, depois de um tempo de convivência, tirou os óculos diante de mim, arregalou os olhos e disse:

Todo mundo fala que eu deveria parar de usar óculos, pois desvalorizam meus olhos. Você já viu os meus olhos?

A cena foi cômica. A mulher com os olhos esbugalhados na minha frente mendigando elogios.  Lhe respondi:

– Fulana, eu já vi os seus olhos.

 Ela, muito sem graça, recolocou os óculos. O que ela queria de mim? O que todo mundo lhe dava: bajulação da sua corporeidade branca, dos seus olhos verdes e o reconhecimento do seu valor em base a isto. 

Muitas dessas mulheres tentam reproduzir a mesma hierarquia social e racial que temos no Brasil, procurando por outras que estejam à disposição do ego delas. Conheci uma promotora de justiça de Brasília que chegou na França, juntamente com o marido para fazer mestrado. Os dois conseguiram uma licença de um ano do trabalho. No primeiro contato que tivemos ela perguntou: “Você conhece uma diarista para me apresentar?” Achei estranho o pedido, pois a mulher e o marido ficariam um ano sem trabalhar, morando em um pequeno apartamento, como ela descreveu, mas tinha que ter alguém para lhe servir. Essa gente fora do Brasil e das relações de dominação/servidão/ que se dão em base à racialização de corpos se perde. 

Conheci brasileiras aqui que gostam de conviver com outras brasileiras porque entre nós, entendemos os códigos, as hierarquias e as leis ocultas do nosso país para reproduzir a mesma lógica de quem adora e de quem é adorado. Ou, em outros casos, preferem conviver somente com franceses, pois segundo elas, “não gostam de se misturar” e se agarram aos “brancos mais brancos” como se fosse um troféu para mostrar ao mundo e exibir para a família e amigos no Brasil: “Olha a minha amiga francesa!!!”. É um modo de participar da branquitude mais “pura” (mesmo que indiretamente), que o que temos nas terras Brasilis. 

Uma coisa é certa, essa experiência na Europa poderia ser, para elas, uma grande chance de mudar de paradigma, de renascer, de se tornar uma pessoa melhor. Mas, na maioria dos casos, o privilégio é buscado com unhas e dentes. Se soubessem que podem abandoná-lo e viver mais livres, talvez o fariam. Mas alguém como elas, ou seja, branco, precisaria dizer. Pois, no meu caso, se lhes digo, passo por negra raivosa, ressentida, invejosa, que vê racismo em tudo. Eu torço pela mudança e pela emancipação humana, mas enquanto isso não acontece, continuo tendo-as como objeto de análise e estudo.

Out of Savannastan by Tim Flannery (New York Review of Books)

New York Review of Books, November 4, 2021

By Tim Flannery

Ancient Bones: Unearthing the Astonishing New Story of How We Became Human by Madelaine Böhme, Rüdiger Braun, and Florian Breier, translated from the German by Jane Billinghurst and with a foreword by David R. Begun. Greystone, 337 pp., $34.95

In 1863 the biologist T.H. Huxley proposed an African origin for humanity. Known as “Darwin’s bulldog” for his ferocious defense of Darwin’s evolutionary theory, he had been struck by the distribution in Africa of our nearest living relatives, the common chimpanzee and the gorilla. (The latter had first been described by Europeans just sixteen years earlier, in 1847.) Darwin himself, however, demurred. Aware of the discovery of fossils of apes in Europe dating to the Miocene Epoch (around 23 to 5 million years ago), he opined that “since so remote a period the Earth has certainly undergone many great revolutions, and there has been ample time for migration on the largest scale.”

It was the pioneering and indefatigable Leakey family who found evidence for Huxley’s narrowly supported hypothesis. Louis and Mary Leakey began their search for fossils of human ancestors in Olduvai Gorge, in what is now Tanzania, in the 1930s. Amid the dust, sweat, and inconvenience of remote field camps, they simultaneously dug for fossils and raised three boys, often finding nothing of significance for years at a time. Then, in 1959, Mary discovered a fossilized skull that made headlines around the world. Paranthropus boisei, as it became known, belonged to a male upright ape who had stood around five feet high, weighed 110 pounds, and lived 1.8 million years ago. With powerful teeth and a prominent crest atop his braincase to anchor prodigious chewing muscles, he was an archetypal “ape man.” I recall as a child staring awestruck at a painting of Paranthropus that combined the features of gorillas, chimps, and humans, and that powerfully cemented in my mind the idea that Africa had been humanity’s cradle.

A few months after this discovery, the Leakeys made a second, even more significant find—a jaw attributable to an early member of our own genus. Homo habilis, or “Handy Man,” was a toolmaker hailed as the oldest “true” human ever discovered. After that, the discoveries just kept coming. In 1974 an international team in Ethiopia led by the paleoanthropologist Donald Johanson unearthed the skeleton of the three-foot-tall bipedal ape Australopithecus afarensis, who became popularly known as Lucy. With a catchy name and providing powerful, easy-to-understand support for an African origin, Lucy soon became a household name. Four years later Mary Leakey found 3.6-million-year-old hominin footprints at Laetoli, Tanzania, providing the earliest evidence of bipedalism.

In 1984 a team led by Louis and Mary Leakey’s son Richard unearthed a skeleton of Homo erectus at Lake Turkana in northern Kenya that was 90 percent complete. It seemed as if these astonishing African fossils illustrated most of the important steps in the human evolutionary story. When, beginning in the 1980s, genetic evidence suggested that our species (Homo sapiens) originated in Africa, the case seemed settled: Huxley, rather than Darwin, had been right about our origins. Some researchers began elaborating an all-encompassing Out of Africa theory, which had three components: (1) our hominin lineage (which split from chimpanzees between 13 and 7 million years ago) arose in Africa; (2) our genus, Homo, arose in Africa about 2.3 million years ago, and (3) our species originated in Africa about 300,000 years ago.

But there were always a few dissenters who, like Darwin, felt that the significance of fossilized fragments from Europe and Asia had been overlooked. They pointed to a suspicious gap in the African fossil record between 12 and 6 million years ago, just when the human and chimpanzee lineages were diverging. And some worried that the Leakeys and others had found fossils only where they looked for them—in Africa. If equivalent effort was put in elsewhere, skeptics argued, important finds might be made.

These objections had long been ignored, but now, in her splendid and important new book Ancient Bones, Madelaine Böhme and her collaborators Rüdiger Braun and Florian Breier have taken them up. Scientifically rigorous and written with a clarity and candor that create a gripping tale, it presents a powerful challenge to proponents of the Out of Africa hypothesis. The book begins with a foreword by one of the earliest and most prominent objectors to the hypothesis, the University of Toronto professor David R. Begun. Begun believes that apes became extinct in Africa around 12 million years ago and that our earliest direct ancestors evolved in Europe, which is rich in ape fossils from 12 to 6 million years old. Böhme, a terrestrial paleoclimatologist and paleoanthropologist at the University of Tübingen, has excavated and researched many specimens of European apes herself, and her account of the history of Europe’s lost apes is imbued with the sweat, grime, and triumph that is the lot of the fieldworker, and carries great authority.

As Böhme illustrates, the evolution of the human lineage is complex. A crucial event occurred around 25 million years ago, when the apes and Old World monkeys originated from a common ancestor in East Africa. The monkeys flourished in Africa, but as time went on the apes dwindled, until around 16 million years ago some reached Europe, where they thrived. Climatic changes in Europe, including increased seasonality, seem to have favored their diversification, and twelve genera are now known from the European Miocene, varying from gibbon-like creatures that swung through the forest canopy to gorilla-sized, presumably terrestrial ramblers.

As oak and beech trees started to crowd out the tropical vegetation that had dominated Europe till then, the apes were forced to alter their diet. Depending on which part of Europe they lived in, they had to go for between two and four months without fresh leaves, fruits, or nuts. Around 15 million years ago, a genetic mutation occurred that resulted in their inability to produce uricase, the enzyme used by mammals to break down uric acid so that it can be excreted in urine. This mutation led to high levels of uric acid in the apes’ blood, allowing them to rapidly convert fructose into fat. And fat, stored in the liver and other tissues, is an energy reserve that made it possible for the apes to survive lean seasons.

I often curse this adaptation, for I’m a victim of that singularly painful condition, gout, which is caused by a buildup of uric acid in the blood. Were it not for the availability of uricase in pill form (thank God for modern medicine!), I’d be a bedridden old grouch by now. But gout is just one of the many “diseases of civilization” inflicted on us by this adaptation in our ape ancestors. Diabetes, obesity, high blood pressure, and heart disease are all related to some degree to the loss, in some long-extinct European ape, of the ability to remove uric acid from the blood.

One of Böhme’s most important fossil finds was made near Kaufbeuren, in southern Germany. There, while visiting a lignite pit, she examined small black lumps of what was supposedly coal, only to discover that they were ancient bones. The deposit was about to be mined and destroyed, and, with no alternative, Böhme asked that twenty-five tons of fossil-rich sediment be scooped up and dumped where paleontologists could sort through it without interrupting the quarrying. After two field seasons of arduous work, she recovered 15 percent of the skeleton of a single great ape, along with fragments from three others. Named Danuvius guggenmosi, the creature had lived 11.62 million years ago, in a subtropical environment. At just three feet tall and weighing around sixty-five pounds, Danuvius had big, powerful thumbs and toes and an elongated lower back that permitted an upright stance. Böhme quips that “from the waist up he looked like an ape and from the waist down he looked like an early hominin.” Danuvius is in fact one of the candidates for the last common ancestor of chimps and humans.

As the climate cooled later in the Miocene, savanna replaced forest in some parts of Europe, and this had a big impact on the continent’s apes. According to Böhme, a crucial piece of evidence indicating what happened was unearthed in June 1944, when besieged German soldiers dug a bunker near Athens. Bruno von Freyberg, a geology professor from Erlangen who was then serving in the German army, asked his workers to alert him to any fossils they encountered. Despite having lost an arm in World War I, Freyberg personally unearthed the finds, including the jaw of an ape, then sent his fossils to the Natural History Museum in Berlin for safekeeping. But the museum was bombed on February 3, 1945, and the priceless jawbone was severely damaged, losing most of its teeth.

In 1969 the great paleoanthropologist Gustav Heinrich Ralph von Koenigswald examined the damaged bone and named it Graecopithecus freybergi—Freyberg’s Greek ape. But it was so extensively mangled that other researchers concluded it was not identifiable, and so sought to suppress Koenigswald’s name. The jawbone might have been forgotten altogether but for Böhme, who tracked it down to a long-forgotten safe in a university department. When she had the jaw x-rayed, she saw that the roots of the teeth shared unique features with those of the subfamily Homininae, to which humans belong. She also redated the find, establishing that it was 7.175 million years old.

Her conclusion that the oldest human ancestor had lived in Greece around six to seven million years ago was so inconsistent with the dominant Out of Africa hypothesis that the paleoanthropological community largely reacted with stunned silence. But then, within months of Böhme’s analysis of Graecopithecus being published in 2017, a second, even more stunning and unexpected discovery was announced.

In 2002 the Polish paleontologist Gerard Gierliński had been vacationing with his girlfriend near Trachilos, Crete. On a slab of rock by the water he saw oblong marks that he recognized as fossilized footprints. But he didn’t follow up until 2010, when he mentioned them to a colleague; the two scientists hypothesized that the footprints might have been made by a bipedal ape. Analysis revealed that the feet that had left the tracks were small (between 4 and 8.5 inches long) and had five toes, a pronounced ball of the foot, and a big toe aligned with the other toes. The feet that left the prints undeniably resembled humans’ feet but lacked some features, such as an arch. Astonishingly, dating revealed that the prints were made more than six million years ago, when Crete was a long, southward-projecting peninsula of Europe.

I recall my own skepticism upon reading of this find: the discovery of six-million-year-old humanlike footprints on a Greek island seemed too outlandish. And evidently the paleoanthropological community felt similarly, for Gierliński and his colleagues had tried in vain for six and a half years to get their results published. According to Böhme, the manuscript was repeatedly rejected by anonymous reviewers whose reasoning was often difficult to decipher. But following the publication of Böhme’s reanalysis of Graecopithecus, Gierliński’s paper on the Trachilos footprints finally made it to press.

Böhme thinks that the tracks could have been left by Graecopithecus around the time upright apes migrated from Europe back to Africa, allowing them to repopulate a continent that they had been absent from for six million years. Whatever the case, there is no doubt that Graecopithecus and the Trachilos footprints present a strong challenge to the first part of the Out of Africa theory.

To most proponents of the Out of Africa theory, many of whom have invested lifetimes excavating sites in Africa, claims about human origins in Europe are heretical. A sense of just how high the stakes are can be gained from the controversy surrounding the discovery at the turn of the twenty-first century of the skull of Sahelanthropus tchadensis, a hominid species. The skull—which was found in the desert in Chad and studied by Professor Michel Brunet, then at the University of Poitiers—is thought to be six million years old and has been used to support the theory that the oldest human ancestor lived in North Africa six to seven million years ago. This finding has been widely accepted and celebrated: there is a street on the campus in Poitiers named for Brunet, and a parking garage named for Toumaï, as the skull is popularly known.

The skull is horribly fractured, and the area where it articulated with the spinal column is heavily damaged. The reconstruction by Brunet’s team made it appear that the skull sat atop the vertebral column, as it does in bipedal apes. But others disagreed, saying that the articulation was farther back, as in gorillas. Indeed, critics say, the skull has a number of gorilla-like features and may belong to an ancestral gorilla.

There matters might have remained, if not for the publication of a photograph of the skull as it was upon discovery. It lay in sand, surrounded by a scatter of other bones including a thighbone that was possibly part of the same individual as the Sahelanthropus skull. While Brunet was doing fieldwork, Aude Bergeret, a Ph.D. student who was studying the bones in her lab, concluded that the thighbone belonged to a great ape and that Sahelanthropus was not bipedal. According to Böhme, when Bergeret’s assertion became known, “the thighbone disappeared without a trace and the doctoral student lost her position at the university.”

In 2018 Bergeret and a colleague offered to give a presentation on the thighbone at the annual meeting of the Société d’Anthropologie de Paris, but they were refused. “Could it be,” Böhme asks, “that Michel Brunet, one of the icons of French science, Knight of the Légion d’honneur, recipient of the Ordre national du Mérite, did not want to be challenged?”

Questions about Sahelanthropus continue to pile up. Because the bones were found not in the sediments that preserved them but in sand drifts, it is unclear how old they are. And is Sahelanthropus an early gorilla or a member of the human lineage? The fossil record of gorillas is almost entirely unknown, so the discovery of an ancestral gorilla would be of huge significance. But it’s hard to imagine a street in a university being named for the discoverer of such a fossil.

The second part of the Out of Africa hypothesis states that the genus Homo evolved in Africa. Böhme strongly challenges this, arguing instead that our genus evolved in a great, now fragmented grassy woodland known as Savannastan, which covered parts of Europe, Asia, and Africa 2.6 million years ago. In support of the idea, she cites 1.8-million-year-old Homo skeletons from Georgia and, more intriguingly, a jaw and a few isolated teeth found in cave sediments in Longgupo Cave, in Wushan County in China’s Sichuan Province. The Chinese fossils were named as a new species, Homo wushanensis, by researchers in 1991, and according to Böhme the remains are between 2.6 and 2.48 million years old. As the oldest Homo habilis remains from Africa are only 2.3 million years old, the dating of the Chinese finds, if verified, would pose a direct challenge to part two of the Out of Africa hypothesis.

But interpretation of the fragmented remains of Homo wushanensis is complicated. In 2009 Russell Ciochon, an American researcher who described Homo wushanensis, declared that he had made a mistake. The jaw and some of the teeth did not belong to an early human, he said, but to one or more “mystery apes.”

 His retraction was acclaimed by some as a welcome act of intellectual honesty in a field characterized by fierce rivalry. Yet it has hardly settled matters. Böhme, for example, notes that stone tools were also found in Longgupo Cave, suggesting the presence of early humans. Others have speculated that the tools (along with some of the teeth) may have found their way into the deposit from more recent sediments, but Böhme is not satisfied by this explanation. Instead, she asks of Ciochon’s retraction, “Why the spectacular retreat? Was it to avoid jeopardizing the Out of Africa…hypothesis?”

Böhme, it seems, is just as determined to defend her hypothesis as the Out of Africanistas are to defend theirs.

Ancient Bones makes clear that Graecopithecus and the Trachilos footprints provide convincing evidence that our earliest direct ancestors evolved in Europe, and that they were walking upright as early as six million years ago. But the book, I think, is overly confident in its challenge to the idea that the genus Homo arose in Africa. That’s because, while there are intriguing clues that Homo may have been present in Europe or Asia before the oldest African finds (which date to around 2.3 million years ago), the evidence is far from conclusive. And of course the third part of the Out of Africa hypothesis, that Homo sapiens evolved in Africa, remains unchallenged—though the recent discovery that all living people carry genes from other hominin lineages, such as Neanderthals and Denisovans, which appear to have evolved in Europe and Asia, respectively, adds an intriguing twist to the tale.

What Ancient Bones does make clear, however, is that we place far too much emphasis on rewarding the discovery of our ancestors. In science, a discovery that leads in an unexpected direction, or even to a dead end, is often as productive as a lucky find. If we could only get past the great egos that swell in the field of paleoanthropology and reward the search as much as we do the discovery! But that, perhaps, would require an objectivity and generosity that aren’t entirely human.

Our brains exist in a state of “controlled hallucination” (MIT Technology Review)

technologyreview.com

Matthew Hutson – August 25, 2021

Three new books lay bare the weirdness of how our brains process the world around us.

Eventually, vision scientists figured out what was happening. It wasn’t our computer screens or our eyes. It was the mental calculations that brains make when we see. Some people unconsciously inferred that the dress was in direct light and mentally subtracted yellow from the image, so they saw blue and black stripes. Others saw it as being in shadow, where bluish light dominates. Their brains mentally subtracted blue from the image, and came up with a white and gold dress. 

Not only does thinking filter reality; it constructs it, inferring an outside world from ambiguous input. In Being You, Anil Seth, a neuroscientist at the University of Sussex, relates his explanation for how the “inner universe of subjective experience relates to, and can be explained in terms of, biological and physical processes unfolding in brains and bodies.” He contends that “experiences of being you, or of being me, emerge from the way the brain predicts and controls the internal state of the body.” 

Prediction has come into vogue in academic circles in recent years. Seth and the philosopher Andy Clark, a colleague at Sussex, refer to predictions made by the brain as “controlled hallucinations.” The idea is that the brain is always constructing models of the world to explain and predict incoming information; it updates these models when prediction and the experience we get from our sensory inputs diverge. 

“Chairs aren’t red,” Seth writes, “just as they aren’t ugly or old-fashioned or avant-garde … When I look at a red chair, the redness I experience depends both on properties of the chair and on properties of my brain. It corresponds to the content of a set of perceptual predictions about the ways in which a specific kind of surface reflects light.” 

Seth is not particularly interested in redness, or even in color more generally. Rather his larger claim is that this same process applies to all of perception: “The entirety of perceptual experience is a neuronal fantasy that remains yoked to the world through a continuous making and remaking of perceptual best guesses, of controlled hallucinations. You could even say that we’re all hallucinating all the time. It’s just that when we agree about our hallucinations, that’s what we call reality.”

Cognitive scientists often rely on atypical examples to gain understanding of what’s really happening. Seth takes the reader through a fun litany of optical illusions and demonstrations, some quite familiar and others less so. Squares that are in fact the same shade appear to be different; spirals printed on paper appear to spontaneously rotate; an obscure image turns out to be a woman kissing a horse; a face shows up in a bathroom sink. Re-creating the mind’s psychedelic powers in silicon, an artificial-intelligence-powered virtual-reality setup that he and his colleagues created produces a Hunter Thompson–esque menagerie of animal parts emerging piecemeal from other objects in a square on the Sussex University campus. This series of examples, in Seth’s telling, “chips away at the beguiling but unhelpful intuition that consciousness is one thing—one big scary mystery in search of one big scary solution.” Seth’s perspective might be unsettling to those who prefer to believe that things are as they seem to be: “Experiences of free will are perceptions. The flow of time is a perception.” 

Seth is on comparatively solid ground when he describes how the brain shapes experience, what philosophers call the “easy” problems of consciousness. They’re easy only in comparison to the “hard” problem: why subjective experience exists at all as a feature of the universe. Here he treads awkwardly, introducing the “real” problem, which is to “explain, predict, and control the phenomenological properties of conscious experience.” It’s not clear how the real problem differs from the easy problems, but somehow, he says, tackling it will get us some way toward resolving the hard problem. Now that would be a neat trick.

Where Seth relates, for the most part, the experiences of people with typical brains wrestling with atypical stimuli, in Coming to Our Senses, Susan Barry, an emeritus professor of neurobiology at Mount Holyoke college, tells the stories of two people who acquired new senses later in life than is usual. Liam McCoy, who had been nearly blind since he was an infant, was able to see almost clearly after a series of operations when he was 15 years old. Zohra Damji was profoundly deaf until she was given a cochlear implant at the unusually late age of 12. As Barry explains, Damji’s surgeon “told her aunt that, had he known the length and degree of Zohra’s deafness, he would not have performed the operation.” Barry’s compassionate, nuanced, and observant exposition is informed by her own experience:

At age forty-eight, I experienced a dramatic improvement in my vision, a change that repeatedly brought me moments of childlike glee. Cross-eyed from early infancy, I had seen the world primarily through one eye. Then, in mid-life, I learned, through a program of vision therapy, to use my eyes together. With each glance, everything I saw took on a new look. I could see the volume and 3D shape of the empty space between things. Tree branches reached out toward me; light fixtures floated. A visit to the produce section of the supermarket, with all its colors and 3D shapes, could send me into a sort of ecstasy. 

Barry was overwhelmed with joy at her new capacities, which she describes as “seeing in a new way.” She takes pains to point out how different this is from “seeing for the first time.” A person who has grown up with eyesight can grasp a scene in a single glance. “But where we perceive a three-dimensional landscape full of objects and people, a newly sighted adult sees a hodgepodge of lines and patches of colors appearing on one flat plane.” As McCoy described his experience of walking up and down stairs to Barry: 

The upstairs are large alternating bars of light and dark and the downstairs are a series of small lines. My main focus is to balance and step IN BETWEEN lines, never on one … Of course going downstairs you step in between every line but upstairs you skip every other bar. All the while, when I move, the stairs are skewing and changing.

Even a sidewalk was tricky, at first, to navigate. He had to judge whether a line “indicated the junction between flat sidewalk blocks, a crack in the cement, the outline of a stick, a shadow cast by an upright pole, or the presence of a sidewalk step,” Barry explains. “Should he step up, down, or over the line, or should he ignore it entirely?” As McCoy says, the complexity of his perceptual confusion probably cannot be fully explained in terms that sighted people are used to.

The same, of course, is true of hearing. Raw audio can be hard to untangle. Barry describes her own ability to listen to the radio while working, effortlessly distinguishing the background sounds in the room from her own typing and from the flute and violin music coming over the radio. “Like object recognition, sound recognition depends upon communication between lower and higher sensory areas in the brain … This neural attention to frequency helps with sound source recognition. Drop a spoon on a tiled kitchen floor, and you know immediately whether the spoon is metal or wood by the high- or low-frequency sound waves it produces upon impact.” Most people acquire such capacities in infancy. Damji didn’t. She would often ask others what she was hearing, but had an easier time learning to distinguish sounds that she made herself. She was surprised by how noisy eating potato chips was, telling Barry: “To me, potato chips were always such a delicate thing, the way they were so lightweight, and so fragile that you could break them easily, and I expected them to be soft-sounding. But the amount of noise they make when you crunch them was something out of place. So loud.” 

As Barry recounts, at first Damji was frightened by all sounds, “because they were meaningless.” But as she grew accustomed to her new capabilities, Damji found that “a sound is not a noise anymore but more like a story or an event.” The sound of laughter came to her as a complete surprise, and she told Barry it was her favorite. As Barry writes, “Although we may be hardly conscious of background sounds, we are also dependent upon them for our emotional well-being.” One strength of the book is in the depth of her connection with both McCoy and Damji. She spent years speaking with them and corresponding as they progressed through their careers: McCoy is now an ophthalmology researcher at Washington University in St. Louis, while Damji is a doctor. From the details of how they learned to see and hear, Barry concludes, convincingly, that “since the world and everything in it is constantly changing, it’s surprising that we can recognize anything at all.”

In What Makes Us Smart, Samuel Gershman, a psychology professor at Harvard, says that there are “two fundamental principles governing the organization of human intelligence.” Gershman’s book is not particularly accessible; it lacks connective tissue and is peppered with equations that are incompletely explained. He writes that intelligence is governed by “inductive bias,” meaning we prefer certain hypotheses before making observations, and “approximation bias,” which means we take mental shortcuts when faced with limited resources. Gershman uses these ideas to explain everything from visual illusions to conspiracy theories to the development of language, asserting that what looks dumb is often “smart.”

“The brain is evolution’s solution to the twin problems of limited data and limited computation,” he writes. 

He portrays the mind as a raucous committee of modules that somehow helps us fumble our way through the day. “Our mind consists of multiple systems for learning and decision making that only exchange limited amounts of information with one another,” he writes. If he’s correct, it’s impossible for even the most introspective and insightful among us to fully grasp what’s going  on inside our own head. As Damji wrote in a letter to Barry: 

When I had no choice but to learn Swahili in medical school in order to be able to talk to the patients—that is when I realized how much potential we have—especially when we are pushed out of our comfort zone. The brain learns it somehow.

A real-time revolution will up-end the practice of macroeconomics (The Economist)

The Economist Oct 23rd 2021


DOES ANYONE really understand what is going on in the world economy? The pandemic has made plenty of observers look clueless. Few predicted $80 oil, let alone fleets of container ships waiting outside Californian and Chinese ports. As covid-19 let rip in 2020, forecasters overestimated how high unemployment would be by the end of the year. Today prices are rising faster than expected and nobody is sure if inflation and wages will spiral upward. For all their equations and theories, economists are often fumbling in the dark, with too little information to pick the policies that would maximise jobs and growth.

Yet, as we report this week, the age of bewilderment is starting to give way to greater enlightenment. The world is on the brink of a real-time revolution in economics, as the quality and timeliness of information are transformed. Big firms from Amazon to Netflix already use instant data to monitor grocery deliveries and how many people are glued to “Squid Game”. The pandemic has led governments and central banks to experiment, from monitoring restaurant bookings to tracking card payments. The results are still rudimentary, but as digital devices, sensors and fast payments become ubiquitous, the ability to observe the economy accurately and speedily will improve. That holds open the promise of better public-sector decision-making—as well as the temptation for governments to meddle.

The desire for better economic data is hardly new. America’s GNP estimates date to 1934 and initially came with a 13-month time lag. In the 1950s a young Alan Greenspan monitored freight-car traffic to arrive at early estimates of steel production. Ever since Walmart pioneered supply-chain management in the 1980s private-sector bosses have seen timely data as a source of competitive advantage. But the public sector has been slow to reform how it works. The official figures that economists track—think of GDP or employment—come with lags of weeks or months and are often revised dramatically. Productivity takes years to calculate accurately. It is only a slight exaggeration to say that central banks are flying blind.

Bad and late data can lead to policy errors that cost millions of jobs and trillions of dollars in lost output. The financial crisis would have been a lot less harmful had the Federal Reserve cut interest rates to near zero in December 2007, when America entered recession, rather than in December 2008, when economists at last saw it in the numbers. Patchy data about a vast informal economy and rotten banks have made it harder for India’s policymakers to end their country’s lost decade of low growth. The European Central Bank wrongly raised interest rates in 2011 amid a temporary burst of inflation, sending the euro area back into recession. The Bank of England may be about to make a similar mistake today.

The pandemic has, however, become a catalyst for change. Without the time to wait for official surveys to reveal the effects of the virus or lockdowns, governments and central banks have experimented, tracking mobile phones, contactless payments and the real-time use of aircraft engines. Instead of locking themselves in their studies for years writing the next “General Theory”, today’s star economists, such as Raj Chetty at Harvard University, run well-staffed labs that crunch numbers. Firms such as JPMorgan Chase have opened up treasure chests of data on bank balances and credit-card bills, helping reveal whether people are spending cash or hoarding it.

These trends will intensify as technology permeates the economy. A larger share of spending is shifting online and transactions are being processed faster. Real-time payments grew by 41% in 2020, according to McKinsey, a consultancy (India registered 25.6bn such transactions). More machines and objects are being fitted with sensors, including individual shipping containers that could make sense of supply-chain blockages. Govcoins, or central-bank digital currencies (CBDCs), which China is already piloting and over 50 other countries are considering, might soon provide a goldmine of real-time detail about how the economy works.

Timely data would cut the risk of policy cock-ups—it would be easier to judge, say, if a dip in activity was becoming a slump. And the levers governments can pull will improve, too. Central bankers reckon it takes 18 months or more for a change in interest rates to take full effect. But Hong Kong is trying out cash handouts in digital wallets that expire if they are not spent quickly. CBDCs might allow interest rates to fall deeply negative. Good data during crises could let support be precisely targeted; imagine loans only for firms with robust balance-sheets but a temporary liquidity problem. Instead of wasteful universal welfare payments made through social-security bureaucracies, the poor could enjoy instant income top-ups if they lost their job, paid into digital wallets without any paperwork.

The real-time revolution promises to make economic decisions more accurate, transparent and rules-based. But it also brings dangers. New indicators may be misinterpreted: is a global recession starting or is Uber just losing market share? They are not as representative or free from bias as the painstaking surveys by statistical agencies. Big firms could hoard data, giving them an undue advantage. Private firms such as Facebook, which launched a digital wallet this week, may one day have more insight into consumer spending than the Fed does.

Know thyself

The biggest danger is hubris. With a panopticon of the economy, it will be tempting for politicians and officials to imagine they can see far into the future, or to mould society according to their preferences and favour particular groups. This is the dream of the Chinese Communist Party, which seeks to engage in a form of digital central planning.

In fact no amount of data can reliably predict the future. Unfathomably complex, dynamic economies rely not on Big Brother but on the spontaneous behaviour of millions of independent firms and consumers. Instant economics isn’t about clairvoyance or omniscience. Instead its promise is prosaic but transformative: better, timelier and more rational decision-making. ■

Enter third-wave economics

Oct 23rd 2021


AS PART OF his plan for socialism in the early 1970s, Salvador Allende created Project Cybersyn. The Chilean president’s idea was to offer bureaucrats unprecedented insight into the country’s economy. Managers would feed information from factories and fields into a central database. In an operations room bureaucrats could see if production was rising in the metals sector but falling on farms, or what was happening to wages in mining. They would quickly be able to analyse the impact of a tweak to regulations or production quotas.

Cybersyn never got off the ground. But something curiously similar has emerged in Salina, a small city in Kansas. Salina311, a local paper, has started publishing a “community dashboard” for the area, with rapid-fire data on local retail prices, the number of job vacancies and more—in effect, an electrocardiogram of the economy.

What is true in Salina is true for a growing number of national governments. When the pandemic started last year bureaucrats began studying dashboards of “high-frequency” data, such as daily airport passengers and hour-by-hour credit-card-spending. In recent weeks they have turned to new high-frequency sources, to get a better sense of where labour shortages are worst or to estimate which commodity price is next in line to soar. Economists have seized on these new data sets, producing a research boom (see chart 1). In the process, they are influencing policy as never before.

This fast-paced economics involves three big changes. First, it draws on data that are not only abundant but also directly relevant to real-world problems. When policymakers are trying to understand what lockdowns do to leisure spending they look at live restaurant reservations; when they want to get a handle on supply-chain bottlenecks they look at day-by-day movements of ships. Troves of timely, granular data are to economics what the microscope was to biology, opening a new way of looking at the world.

Second, the economists using the data are keener on influencing public policy. More of them do quick-and-dirty research in response to new policies. Academics have flocked to Twitter to engage in debate.

And, third, this new type of economics involves little theory. Practitioners claim to let the information speak for itself. Raj Chetty, a Harvard professor and one of the pioneers, has suggested that controversies between economists should be little different from disagreements among doctors about whether coffee is bad for you: a matter purely of evidence. All this is causing controversy among dismal scientists, not least because some, such as Mr Chetty, have done better from the shift than others: a few superstars dominate the field.

Their emerging discipline might be called “third wave” economics. The first wave emerged with Adam Smith and the “Wealth of Nations”, published in 1776. Economics mainly involved books or papers written by one person, focusing on some big theoretical question. Smith sought to tear down the monopolistic habits of 18th-century Europe. In the 20th century John Maynard Keynes wanted people to think differently about the government’s role in managing the economic cycle. Milton Friedman aimed to eliminate many of the responsibilities that politicians, following Keynes’s ideas, had arrogated to themselves.

All three men had a big impact on policies—as late as 1850 Smith was quoted 30 times in Parliament—but in a diffuse way. Data were scarce. Even by the 1970s more than half of economics papers focused on theory alone, suggests a study published in 2012 by Daniel Hamermesh, an economist.

That changed with the second wave of economics. By 2011 purely theoretical papers accounted for only 19% of publications. The growth of official statistics gave wonks more data to work with. More powerful computers made it easier to spot patterns and ascribe causality (this year’s Nobel prize was awarded for the practice of identifying cause and effect). The average number of authors per paper rose, as the complexity of the analysis increased (see chart 2). Economists had greater involvement in policy: rich-world governments began using cost-benefit analysis for infrastructure decisions from the 1950s.

Second-wave economics nonetheless remained constrained by data. Most national statistics are published with lags of months or years. “The traditional government statistics weren’t really all that helpful—by the time they came out, the data were stale,” says Michael Faulkender, an assistant treasury secretary in Washington at the start of the pandemic. The quality of official local economic data is mixed, at best; they do a poor job of covering the housing market and consumer spending. National statistics came into being at a time when the average economy looked more industrial, and less service-based, than it does now. The Standard Industrial Classification, introduced in 1937-38 and still in use with updates, divides manufacturing into 24 subsections, but the entire financial industry into just three.

The mists of time

Especially in times of rapid change, policymakers have operated in a fog. “If you look at the data right now…we are not in what would normally be characterised as a recession,” argued Edward Lazear, then chairman of the White House Council of Economic Advisers, in May 2008. Five months later, after Lehman Brothers had collapsed, the IMF noted that America was “not necessarily” heading for a deep recession. In fact America had entered a recession in December 2007. In 2007-09 there was no surge in economics publications. Economists’ recommendations for policy were mostly based on judgment, theory and a cursory reading of national statistics.

The gap between official data and what is happening in the real economy can still be glaring. Walk around a Walmart in Kansas and many items, from pet food to bottled water, are in short supply. Yet some national statistics fail to show such problems. Dean Baker of the Centre for Economic and Policy Research, using official data, points out that American real inventories, excluding cars and farm products, are barely lower than before the pandemic.

There were hints of an economics third wave before the pandemic. Some economists were finding new, extremely detailed streams of data, such as anonymised tax records and location information from mobile phones. The analysis of these giant data sets requires the creation of what are in effect industrial labs, teams of economists who clean and probe the numbers. Susan Athey, a trailblazer in applying modern computational methods in economics, has 20 or so non-faculty researchers at her Stanford lab (Mr Chetty’s team boasts similar numbers). Of the 20 economists with the most cited new work during the pandemic, three run industrial labs.

More data sprouted from firms. Visa and Square record spending patterns, Apple and Google track movements, and security companies know when people go in and out of buildings. “Computers are in the middle of every economic arrangement, so naturally things are recorded,” says Jon Levin of Stanford’s Graduate School of Business. Jamie Dimon, the boss of JPMorgan Chase, a bank, is an unlikely hero of the emergence of third-wave economics. In 2015 he helped set up an institute at his bank which tapped into data from its network to analyse questions about consumer finances and small businesses.

The Brexit referendum of June 2016 was the first big event when real-time data were put to the test. The British government and investors needed to get a sense of this unusual shock long before Britain’s official GDP numbers came out. They scraped web pages for telltale signs such as restaurant reservations and the number of supermarkets offering discounts—and concluded, correctly, that though the economy was slowing, it was far from the catastrophe that many forecasters had predicted.

Real-time data might have remained a niche pursuit for longer were it not for the pandemic. Chinese firms have long produced granular high-frequency data on everything from cinema visits to the number of glasses of beer that people are drinking daily. Beer-and-movie statistics are a useful cross-check against sometimes dodgy official figures. China-watchers turned to them in January 2020, when lockdowns began in Hubei province. The numbers showed that the world’s second-largest economy was heading for a slump. And they made it clear to economists elsewhere how useful such data could be.

Vast and fast

In the early days of the pandemic Google started releasing anonymised data on people’s physical movements; this has helped researchers produce a day-by-day measure of the severity of lockdowns (see chart 3). OpenTable, a booking platform, started publishing daily information on restaurant reservations. America’s Census Bureau quickly introduced a weekly survey of households, asking them questions ranging from their employment status to whether they could afford to pay the rent.

In May 2020 Jose Maria Barrero, Nick Bloom and Steven Davis, three economists, began a monthly survey of American business practices and work habits. Working-age Americans are paid to answer questions on how often they plan to visit the office, say, or how they would prefer to greet a work colleague. “People often complete a survey during their lunch break,” says Mr Bloom, of Stanford University. “They sit there with a sandwich, answer some questions, and that pays for their lunch.”

Demand for research to understand a confusing economic situation jumped. The first analysis of America’s $600 weekly boost to unemployment insurance, implemented in March 2020, was published in weeks. The British government knew by October 2020 that a scheme to subsidise restaurant attendance in August 2020 had probably boosted covid infections. Many apparently self-evident things about the pandemic—that the economy collapsed in March 2020, that the poor have suffered more than the rich, or that the shift to working from home is turning out better than expected—only seem obvious because of rapid-fire economic research.

It is harder to quantify the policy impact. Some economists scoff at the notion that their research has influenced politicians’ pandemic response. Many studies using real-time data suggested that the Paycheck Protection Programme, an effort to channel money to American small firms, was doing less good than hoped. Yet small-business lobbyists ensured that politicians did not get rid of it for months. Tyler Cowen, of George Mason University, points out that the most significant contribution of economists during the pandemic involved recommending early pledges to buy vaccines—based on older research, not real-time data.

Still, Mr Faulkender says that the special support for restaurants that was included in America’s stimulus was influenced by a weak recovery in the industry seen in the OpenTable data. Research by Mr Chetty in early 2021 found that stimulus cheques sent in December boosted spending by lower-income households, but not much for richer households. He claims this informed the decision to place stronger income limits on the stimulus cheques sent in March.

Shaping the economic conversation

As for the Federal Reserve, in May 2020 the Dallas and New York regional Feds and James Stock, a Harvard economist, created an activity index using data from SafeGraph, a data provider that tracks mobility using mobile-phone pings. The St Louis Fed used data from Homebase to track employment numbers daily. Both showed shortfalls of economic activity in advance of official data. This led the Fed to communicate its doveish policy stance faster.

Speedy data also helped frame debate. Everyone realised the world was in a deep recession much sooner than they had in 2007-09. In the IMF’s overviews of the global economy in 2009, 40% of the papers cited had been published in 2008-09. In the overview published in October 2020, by contrast, over half the citations were for papers published that year.

The third wave of economics has been better for some practitioners than others. As lockdowns began, many male economists found themselves at home with no teaching responsibilities and more time to do research. Female ones often picked up the slack of child care. A paper in Covid Economics, a rapid-fire journal, finds that female authors accounted for 12% of economics working-paper submissions during the pandemic, compared with 20% before. Economists lucky enough to have researched topics before the pandemic which became hot, from home-working to welfare policy, were suddenly in demand.

There are also deeper shifts in the value placed on different sorts of research. The Economist has examined rankings of economists from IDEAS RePEC, a database of research, and citation data from Google Scholar. We divided economists into three groups: “lone wolves” (who publish with less than one unique co-author per paper on average); “collaborators” (those who tend to work with more than one unique co-author per paper, usually two to four people); and “lab leaders” (researchers who run a large team of dedicated assistants). We then looked at the top ten economists for each as measured by RePEC author rankings for the past ten years.

Collaborators performed far ahead of the other two groups during the pandemic (see chart 4). Lone wolves did worst: working with large data sets benefits from a division of labour. Why collaborators did better than lab leaders is less clear. They may have been more nimble in working with those best suited for the problems at hand; lab leaders are stuck with a fixed group of co-authors and assistants.

The most popular types of research highlight another aspect of the third wave: its usefulness for business. Scott Baker, another economist, and Messrs Bloom and Davis—three of the top four authors during the pandemic compared with the year before—are all “collaborators” and use daily newspaper data to study markets. Their uncertainty index has been used by hedge funds to understand the drivers of asset prices. The research by Messrs Bloom and Davis on working from home has also gained attention from businesses seeking insight on the transition to remote work.

But does it work in theory?

Not everyone likes where the discipline is going. When economists say that their fellows are turning into data scientists, it is not meant as a compliment. A kinder interpretation is that the shift to data-heavy work is correcting a historical imbalance. “The most important problem with macro over the past few decades has been that it has been too theoretical,” says Jón Steinsson of the University of California, Berkeley, in an essay published in July. A better balance with data improves theory. Half of the recent Nobel prize went for the application of new empirical methods to labour economics; the other half was for the statistical theory around such methods.

Some critics question the quality of many real-time sources. High-frequency data are less accurate at estimating levels (for example, the total value of GDP) than they are at estimating changes, and in particular turning-points (such as when growth turns into recession). In a recent review of real-time indicators Samuel Tombs of Pantheon Macroeconomics, a consultancy, pointed out that OpenTable data tended to exaggerate the rebound in restaurant attendance last year.

Others have worries about the new incentives facing economists. Researchers now race to post a working paper with America’s National Bureau of Economic Research in order to stake their claim to an area of study or to influence policymakers. The downside is that consumers of fast-food academic research often treat it as if it is as rigorous as the slow-cooked sort—papers which comply with the old-fashioned publication process involving endless seminars and peer review. A number of papers using high-frequency data which generated lots of clicks, including one which claimed that a motorcycle rally in South Dakota had caused a spike in covid cases, have since been called into question.

Whatever the concerns, the pandemic has given economists a new lease of life. During the Chilean coup of 1973 members of the armed forces broke into Cybersyn’s operations room and smashed up the slides of graphs—not only because it was Allende’s creation, but because the idea of an electrocardiogram of the economy just seemed a bit weird. Third-wave economics is still unusual, but ever less odd. ■

Can Skeletons Have a Racial Identity? (New York Times)

Racial reckonings were happening everywhere in the summer of 2020, after George Floyd was killed in Minneapolis by the police. The time felt right, two forensic anthropologists reasoned, to reignite a conversation about the role of race in their own field, where specialists help solve crimes by analyzing skeletons to determine who those people were and how they died.

Dr. Elizabeth DiGangi of Binghamton University and Jonathan Bethard of the University of South Florida published a letter in The Journal of Forensic Science that questioned the longstanding practice of estimating ancestry, or a person’s geographic origin, as a proxy for estimating race. Ancestry, along with height, age at death and assigned sex, is one of the key details that many forensic anthropologists try to determine.

That fall, they published a longer paper with a more ambitious call to action: “We urge all forensic anthropologists to abolish the practice of ancestry estimation.”

In recent years, a growing number of forensic anthropologists have grown critical of ancestry estimation and want to replace it with something more nuanced.

Criminal cases in which the victim’s identity is entirely unknown are rare. But in these instances, some forensic anthropologists argue, a tool like ancestry estimation can be crucial.

The assessment of race has been a part of forensic anthropology since the field’s inception a century ago. The earliest scholars were white men who studied human skulls to support racist beliefs. Ales Hrdlicka, a physical anthropologist who joined the Smithsonian Institution in 1903, was a eugenicist who looted human remains for his collections and sought to classify humans into different races based on certain appearances and traits.

An expert on skeletons, Dr. Hrdlicka helped law enforcement identify human remains, laying the blueprint for the professional field. Forensic anthropologists thereafter were expected to produce a profile with the “Big Four” — age at death, sex, height and race.

In the 1990s, as more scientists debunked the myth of biological race — the notion that the humans species is divided into distinct races — anthropologists grew sharply divided over the issue. One survey found that 50 percent of physical anthropologists accepted the idea of a biological concept of race, while 42 rejected it. At the time, some researchers still used terms like “Caucasoid,” “Mongoloid” and “Negroid” to describe skeletons, and DNA as a forensic tool was still many years away. Today in the U.S., the field of forensic anthropology is 87 percent white.

In 1992, Norman Sauer, an anthropologist at Michigan State University, suggested dropping the term “race,” which he considered loaded, and replacing it with “ancestry.” The term became universal. But some researchers contend that little changed about the practice.

When Shanna Williams, a forensic anthropologist at the University of South Carolina School of Medicine Greenville, was in graduate school around a decade ago, it was still customary to sort skeletons into one of the “Big Three” possible populations — African, Asian or European.

But Dr. Williams grew suspicious of the idea and the way ancestry was often assigned. She saw skulls designated as “Hispanic,” a term that refers to a language group and has no biological meaning. She considered how the field might try, and fail, to sort her own skull. “My mom is white, and my dad is Black,” she said. “Do I fit that mold? Am I perfectly one thing or the other?”

The body of a skeleton can provide a person’s age or height. But the question of ancestry is reserved for the skull — specifically, features of face and skull bones, known as morphoscopic traits, that vary across different groups of humans and can occur more frequently in certain populations.

One trait, called the post-bregmatic depression, is a small indentation located on top of some people’s heads. For a long time, forensic anthropologists assumed that if the skull was indented, the person may be Black.

But forensic anthropologists know little else about the post-bregmatic depression. “There’s not been any understanding as to why this trait exists, what causes it, and what it means,” Dr. Bethard said.

Moreover, the science linking the trait and African ancestry was flawed. In 2003, Joe Hefner, a forensic anthropologist at Michigan State University, used trait lists from a key textbook, “Skeletal Attribution of Race,” to examine more than 700 skulls for his masters thesis. He found that the post-bregmatic depression was present in only 40 percent of people with African ancestry, and is actually more common in many other populations.

Of the 17 morphoscopic traits typically used to estimate ancestry, only five have been studied for whether they are heritable, making it unclear why the unstudied traits would correspond with specific populations. “There’s been this use and reuse of these traits without a fundamental understanding of what they even are,” Dr. Bethard said.

Nonetheless, Dr. Hefner said, if nothing is known about a victim beyond the shape of their skull, ancestry might hold the key to their identity.

He cited a recent example in Michican in which the police had a skull that they believed belonged to a missing woman, one of two who were reported missing in the county at the time. When Dr. Hefner examined it and searched the list of missing people in the area, he concluded that the skull might have come from a missing Southeast Asian male. “They sent us his dental records over and five minutes later we had identified this person,” Dr. Hefner said.

Dr. DiGangi worries that these estimations could suggest to the police that biological race is real and increase racial bias. “When I say to the police, ‘OK, I took these measurements, I looked at these things on the skull and this person is African-American,’ of course they’re going to think it’s biological,” Dr. DiGangi said. “Why would they not?”

To what extent this concern plays out in the real world is hard to measure, however.

For the past two years, Ann Ross, a forensic anthropologist at North Carolina State University, has pushed the American Academy of Forensic Sciences Standards Board to replace ancestry estimation with something new: population affinity.

Whereas ancestry aims to trace back to a continent of origin, population affinity aims to align someone with a population, such as Panamanian. This more nuanced framework looks at how the larger history of a place or community can lead to significant differences between populations that are otherwise geographically close.

A recent paper by Dr. Ross and Dr. Williams, who are close friends, examines Panama and Colombia as a test case. An ancestry estimation might suggest people from both countries would have similarly shaped skulls. But population affinity acknowledges that the trans-Atlantic slave trade and colonization by Spain resulted in new communities living in Panama that changed the makeup of the country’s population. “Because of those historical events, individuals from Panama are very, very different from those from Colombia,” said Dr. Ross, who is Panamanian.

Dr. Ross even designed her own software, 3D-ID, in place of Fordisc, the most commonly used forensic software that categorizes skulls into inconsistent terms: White. Black. Hispanic. Guatemalan. Japanese.

Other anthropologists say that, for all practical purposes, their own ancestry estimations have become affinity estimations. Kate Spradley, a forensic anthropologist at Texas State University, works with the unidentified remains of migrants found near the U.S.-Mexico border. “When we reference data that uses local population groups, that’s really affinity, not ancestry,” Dr. Spradley said.

In her work, Dr. Spradley uses missing persons’ databases from multiple countries that do not always share DNA data. The bones are often weathered, fragmenting the DNA. Estimating affinity can “help to provide a preponderance of evidence,” Dr. Spradley said.

Still, Dr. DiGangi said that switching to affinity may not address racial biases in law enforcement. Until she sees evidence that bias does not preclude people from becoming identified, she says, she does not want a “checkbox” that gets at ancestry or affinity.

As of mid-October, Dr. Ross is waiting for the American Academy of Forensic Sciences Standards Board to set a vote to determine whether ancestry estimation should be replaced with population affinity. But the larger debate — over how to bridge the gap between a person’s bones and identity in real life — is far from settled.

“In 10 or 20 years, we might find a better way to do it,” Dr. Williams said. “I hope that’s the case.”

Reunião do governo com Fundação Cacique Cobra Coral irrita empresários (Painel S.A./Folha de S.Paulo)

Painel S.A.

Representante do setor de turismo afirma que governo não pode contar com a sorte

Joana Cunha – 19.out.2021 às 15h06

A recente reunião do Ministério de Minas e Energia com a entidade esotérica Fundação Cacique Cobra Coral, que diz controlar o clima, desagradou representantes do empresariado que vêm, há meses, tentando convencer o governo de que haveria benefício econômico em retomar o horário de verão para resolver o problema energético agravado pela falta de chuva.

Fabio Aguayo, diretor da CNTur, uma das entidades de turismo que defende a mudança no relógio para alongar o tempo de atendimento no comércio e nas atividades de lazer, diz que o encontro do ministério com a Cobra Coral mostra que o governo está preocupado, mas não pode contar com a sorte e esperar um dilúvio para resolver a questão energética.

Para Aguayo, o ministro Bento Albuquerque é “intransigente e cabeça dura”. Ele afirma que deve ser difícil por parte do governo admitir a volta do horário de verão porque o debate tomou um rumo ideológico comparável a cloroquina e tratamento precoce, quando deveria ser mais econômico, científico e estratégico.

O grupo pró-horário de verão iniciado por Aguayo, que tem apoio de associações de bares e restaurantes, argumenta que a medida promoveria alguma economia de energia. Também permitiria estender o funcionamento de atividades ligadas ao lazer e ajudaria os negócios mais afetados na pandemia.

“Eles estão em um momento crítico. Não podem contar com a sorte. Não podem contar com a sorte de que vai ter um dilúvio, um tsunami de chuva no Brasil. Não vai. Ficaram tão fechados nesse mundinho deles da ideologia, agora estão indo para o lado esotérico. É o que restou para eles”, afirma Aguayo.

O ministério divulgou comunicado no domingo (17) dizendo que seu encontro com a Fundação Cacique Cobra Coral não foi pedido pela pasta. ​

Por ‘tragédia energética’, ministério se reúne com ONG Cacique Cobra Coral (UOL)

Para conversar com uma instituição que alertava para uma “tragédia econômica e energética” decorrente da falta de chuvas, servidores do Ministério das Minas e Energia (MME) se reuniram com representantes da Fundação Cacique Cobra Coral (FCCC). Em seu site, a ONG informa que é presidida por uma “médium que incorpora o espírito e mentor Cacique Cobra Coral, que também já teria sido de Galileu Galilei e Abraham Lincoln”.

A fundação pediu uma audiência com o ministro Bento Albuquerque porque previa “blackout no Centro-Sul [do país] a partir de 16/10/21 se medidas urgentes não forem adotadas”, de acordo com transcrição de email de 2 de setembro, enviada ao UOL pela assessoria de imprensa do Ministério neste domingo (17).

O tempo seco já afeta o meio ambiente, preços das contas de luz e dos alimentos e o abastecimento de água em algumas regiões —especialistas dizem que, se não houver muita chuva nos próximos meses, a situação tende a se agravar.

“Vimos pelo presente solicitar uma audiência extra agenda para para [sic] ontem, afim [sic] de tratarmos da tragédia econômica x energética acima e os meios para recuperar tais precipitações irregulares no lugar certo ainda na estação inverno que se finda e primavera, cujo verão precisará ser antecipado ja [sic] na primavera”, diz o email divulgado pelo governo federal.

Ministro não participou de encontro

O remetente da correspondência era Osmar Santos, que usou seu email profissional, da “Cacique Cobra Coral Foundation” (cuja tradução livre é Fundação Cacique Cobra Coral) e assinou o texto como responsável pelo setor de “relações governamentais” da seguradora Tunikito, “mantenedora oficial da http://www.fccc.org.br”, o site da Fundação Cacique Cobra Coral.

A reunião foi realizada por videoconferência na quinta-feira passada (14), com servidores da Secretaria de Energia Elétrica do ministério, segundo a assessoria.

“O Ministro de Minas e Energia sequer foi informado acerca da citada solicitação de audiência e igualmente não participou da referida reunião”, afirmou a pasta —apesar de o próprio site do governo indicar que a secretaria faz parte do ministério.

Um dos servidores que participaram do encontro foi o diretor do Departamento de Monitoramento do Sistema Elétrico, Guilherme Silva de Godoi. Em sua agenda, consta reunião com a “FCCC”, a sigla da fundação.

Fundação anunciou fazer “previsões”, diz ministério

Segundo a assessoria da pasta comandada por Albuqurque, a fundação anunciou que faz previsões diversas sobre a natureza.

“Durante a audiência, o senhor Osmar relatou aos técnicos do MME que o instituto faz serviços de previsões dos mais variados tipos”, diz texto enviado ao UOL. “Destaca-se que o trabalho no MME é pautado, estritamente, na fundamentação técnica, no interesse público e pela transparência nas ações executadas.”

Como servidores públicos, os servidores do MME apenas e tão somente ouviram as informações do senhor Osmar, assim como ocorre em todas as solicitações de audiências que a pasta recebe, prezando pelo diálogo com toda a sociedade”
Assessoria do Ministério das Minas e Energia

O site da fundação afirma que sua missão é “minimizar catástrofes que podem ocorrer em razão dos desequilíbrios provocados pelo homem na natureza”. A instituição não atendeu aos pedidos de esclarecimentos feitos pelo UOL neste domingo.

Mas Osmar Santos disse à revista Veja que a médium da Fundação, Adelaide Scritori, iria trazer “muita chuva” para Minas Gerais a partir de novembro.

A instituição costuma anunciar contratos com governos locais, como com a Prefeitura de São Paulo, o Distrito Federal em 2017 e a Prefeitura do Rio. A FCCC já afirmou ter dado conselhos a ministros do governo Bolsonaro e até fechado parcerias para ajudar no desencalhe de um navio no canal de Suez, no Egito.

“É a data-limite. Alguma coisa tinha que ser feita com urgência”, disse Osmar Santos, porta-voz da médium que incorpora a entidade. Convocação foi feita pelo almirante Bento Albuquerque, ministro de Minas e Energia

Por Plinio Teodoro 15 out 2021 – 14:12


Após ganhar notoriedade nos anos 90, durante os governos FHC, e relegado na era Lula/PT, o Cacique Cobra Coral, entidade invocada pela fundação que leva seu nome para controlar as chuvas, voltou ao Planalto às pressas a pedido do ministro de Minas e Energia, o almirante Bento Albuquerque.

Segundo informações de Cleo Guimarães na revista Veja, Osmar Santos, porta-voz de Adelaide Scritori, médium que incorpora o cacique, o ministro militar determinou à entidade: “Faça chover!”.

A reunião teria acontecido nesta quinta-feira (14). Em agosto, quando o país já estava em plena crise hídrica, a Fundação diz ter enviado ao governo Jair Bolsonaro (Sem partido) um alerta sobre riscos de apagão a partir deste sábado (16).

“É a data-limite. Alguma coisa tinha que ser feita com urgência”, disse Osmar, ressaltando a importância do encontro para por fim à crise hídrica vivida pelo país em decorrência da falta de chuva nos reservatórios das hidrelétricas.

A Fundação garante que a intervenção do “cacique” trará resultados a partir de novembro, quando as chuvas devem cair sobre Minas Gerais e o sul do país.

A fundação também já estaria articulando um encontro com o governador paulista João Doria (PSDB) para acabar com a estiagem no estado.

Posse

O último trabalho realizado pela fundação junto ao governo federal foi na posse de Jair Bolsonaro, em janeiro de 2019, quando teria impedido a chuva durante o evento.

“Apesar de o dia ter amanhecido chuvoso, começou a melhorar após as 13h e foi abrindo. Por onde o presidente e a comitiva passavam, o tempo ia abrindo e permaneceu firme”, disse à época Osmar Santos.

Genomes Show the History and Travels of Indigenous Peoples (Scientific American)

Scientific American

A new study demonstrates “I ka wā mamua, ka wā ma hope,” or “the future is in the past”

October 13, 2021 – DNASocial Justice

Keolu Fox is an assistant professor at the University of California, San Diego, where he is affiliated with the department of anthropology, the Global Health Program, the Halıcıoğlu Data Science Institute, the Climate Action Lab, the Design Lab and the Indigenous Futures Institute. His work focuses on designing and engineering genome sequencing and editing technologies to advance precision medicine for Indigenous communities.

I am the proud descendant of people who, at least 1,000 years ago, made one of the riskiest decisions in human history: to leave behind their homeland and set sail into the world’s largest ocean. As the first Native Hawaiian to be awarded a Ph.D. in genome sciences, I realized in graduate school that there is another possible line of evidence that can give insights into my ancestors’ voyaging history: our moʻokuʻauhau, our genome. Our ancestors’ genomes were shaped by evolutionary and cultural factors, including our migration and the ebb and flow of the Pacific Ocean. They were also shaped by the devastating history of colonialism.

Through analyzing genomes from present-day peoples, we can do incredible things like determine the approximate number of wa‘a (voyaging canoes) that arrived when my ancestors landed on the island of Hawaii or even reconstruct the genomes of some of the legendary chiefs and navigators that discovered the islands of the Pacific. And beyond these scientific and historical discoveries, genomics research can also help us understand and rectify the injustices of the past. For instance, genomics might clarify how colonialism affected things like genetic susceptibility to illness—information crucial for developing population-specific medical interventions. It can also help us reconstruct the history of land use, which might offer new evidence in court cases over disputed territories and land repatriation.

First, let’s examine what we already know from oral tradition and experimental archeology about our incredible voyaging history in the Pacific. Using complex observational science and nature as their guide, my ancestors drew on bird migration patterns, wind and weather systems, ocean currents, the turquoise glint on the bottom of a cloud reflecting a lagoon, and a complex understanding of stars, constellations and physics to find the most remote places in the world. These intrepid voyagers were the first people to launch what Kanaka Maoli (Hawaiian) master navigator Nainoa Thompson refers to as the original “moonshot.”

This unbelievably risky adventure paid off: In less than 50 generations (1,000 years), my ancestors mastered the art of sailing in both hemispheres. Traveling back and forth along an oceanic superhighway the space of Eurasia in double-hulled catamarans filled to the brim with taro, sweet potatoes, pigs and chickens, using the stars at night to navigate and other advanced techniques and technologies, iteratively perfected over time. This would be humankind’s most impressive migratory feat—no other culture in human history has covered so much distance in such a short amount of time.

The history of my voyaging ancestors and their legacy has been passed to us traditionally through our ʻōlelo (language), mo‘olelo (oral history) and hula. As a Kanaka Maoli, I have grown up knowing them: of how Maui pulled the Hawaiian Islands from the sea and how Herb Kāne, Ben Finney, Tommy Holmes, Mau Piailug and many other members of the Polynesian Voyaging Society enabled the first noninstrumental voyage from Tahiti to Hawaii in over 600 years onboard the wa‘a Hōkūle‘a.

Genomes from modern Pacific Islanders have enabled us to reconstruct precise timings, paths and branching patterns, or bifurcations, of these ancient voyages, giving a refined understanding of the order in which many archipelagoes in the Pacific were settled. By working collaboratively with communities, our approach has directly challenged colonial science’s legacy of taking artifacts and genetic materials without consent. Similar tools to the new genomics have no doubt been misused in the past to justify racist and social Darwinist ends. Yet by using genetic data graciously provided by multiple communities across the Pacific, and by allowing them to shape research priorities, my colleagues and I have been able to “I ka wā mamua, ka ma hope,” or “walk backward into the future.”

So how can our knowledge of the genomic past allow us to walk toward this better future? Genome sequence data are not just helpful in providing refined historical information, they also help us understand and treat important contemporary matters such as population-specific disease. The time frame of these ancestors’ arrival in the Pacific, and the order in which the most remote islands in the world were settled, matters for understanding the incidence and severity among Islander populations of many complex diseases today.

Think of our genetic history as a tree, with present-day populations at the tips of branches and older ones closer to the trunk. Moving backward in time—or from the tips to the trunk—you encounter places where two branches, or populations, were descended from the same ancestor. The places where the branches split represent events in settlement histories in which two populations split, often because of a migration to a new place.

These events provide key insights into what geneticists call “founder effects” and “population bottlenecks,” which are extremely important for understanding disease susceptibility. For example, if there is a specific condition in a population at the trunk of a branching event, then populations on islands that are settled later will have a higher chance of presenting that same health condition as well. Founder populations have provided key insights into rare population-specific diseases. Some examples include Ashkenazi Jews and susceptibility to Tay-Sachs disease and Mennonite communities and susceptibility to maple syrup urine disease (MSUD).

This research also sheds important light on colonialism. As European settlers arrived in the Pacific in places such as Hawaii, Tahiti, and Aotearoa (New Zealand), they didn’t just bring the printing press, the Bible and gunpowder, they brought deadly pathogens. In the case of many Indigenous peoples, historical contact with Europeans resulted in a population collapse (a loss of approximately 80 percent of an Indigenous population’s size), mostly as a result of virgin-soilepidemics of diseases such as smallpox. From Hernán Cortés to James Cook, these bottlenecks have shaped the contemporary genetics of Indigenous peoples in ways that directly impact our susceptibility to disease.

By integrating digital sequence information (DSI) from both modern and ancient Indigenous genomes in genetic regions such as the human leukocyte antigen (HLA) system, we can observe a reduction in human genetic variation in contemporary populations, as compared with ancient ones. In this way, we can observe empirically how colonialism has shaped the genomes of modern Indigenous populations.

Today fewer than 1 percent of genome-wide association studies, which identify associations between diseases and genetic variants, and less than 5 percent of clinical trials include Indigenous peoples. We have just begun to develop mRNA vaccine-based therapies that have already shown their ability to “save the world.” Given their success and potential, why not design treatments, such as gene therapies, that are population specific and reflect the local complexity that speaks to Indigenous peoples’ unique migratory histories and experiences with colonialism?

Finally, genomics also has the potential to impact the politics of Indigenous rights and specifically how we think about the history of land stewardship and belonging. For instance, emerging genomics evidence can empirically verify who first lived on contested territories—e.g., indigenous groups could prove how many generations they arrived before colonists—which could be used in a court of law to settle land and resource repatriation claims.

Genetics gives us insights into the impact of both our peoples’ proud history of migration and the shameful legacy of colonialism. We need to encourage the use of these data to design treatments for the least, the last, the looked over and the left out, and to generate policies and legal decisions that can rectify the history of injustice. In this way, genomics can connect where we come from to where we will go. Once used to make claims about Indigenous peoples’ inferiority, today the science of the genome can be part of an Indigenous future we can all believe in.

Vale tudo para enfrentar a pior seca dos últimos 91 anos, inclusive recorrer à paranormalidade. Porta-voz de Adelaide Scritori – a médium que, ao incorporar o Cacique Cobra Coral, teria o poder de desviar chuvas e controlar o tempo -, Osmar Santos participou nesta quinta (14) de uma reunião com três integrantes da equipe técnica do ministro de Minas e Energia, Bento Albuquerque. O assunto foi um só: a crise hídrica no país.

Osmar diz que em agosto a Fundação enviou um alerta ao governo federal, no qual alertava para os riscos de um apagão, caso a estiagem permanecesse por mais de um mês. O encontro virtual aconteceu nesta quinta (14) e, segundo Guilherme Godoi, um dos técnicos do Ministério na reunião, não houve avanço. “Simplesmente ouvimos o que ele tinha a dizer. Nosso trabalho é técnico”. Já Osmar garante que a médium vai trazer “muita chuva” para Minas Gerais a partir do mês que vem.

A falta de chuvas, como se sabe, reduziu a níveis críticos os reservatórios das usinas hidroelétricas. Por isso, foram acionadas as termoelétricas, que usam combustíveis fósseis, mais caros. O custo é repassado aos consumidores residenciais, comerciais e industriais, o que pressiona a inflação ao produtor e ao consumidor.

Médium alertou o governo para o risco de um apagão neste sábado

É tamanha a certeza expressa, ontem, pelo presidente Bolsonaro de que chuvas recentes em algumas regiões do país afastaram o risco de um apagão de eletricidade que, na última quinta-feira, a convite do ministro Bento Albuquerque, de Minas e Energia, desembarcou às pressas em Brasília o cidadão Osmar Santos.

Osmar é o porta-voz de Adelaide Scritori, a médium paulista que diz incorporar o espírito da entidade Cacique Cobra Coral, detentora do poder de desviar chuvas e controlar o tempo. Osmar contou à VEJA que ouviu o apelo da equipe técnica do ministro: “Faça chover”. E que ele respondeu que o Cacique fará chover.

O encontro deveu-se ao fato de que a médium, em agosto último, alertou o governo federal sobre os riscos de um apagão no país a partir deste sábado, 16 de outubro. “Seria a data limite”, segundo Osmar. “Alguma coisa tinha que ser feita com urgência”. Então se fez a reunião urgente, embora em cima da hora.

Agora está tudo nas mãos de Deus. Ou melhor: do Cacique Cobra Coral.

Governo conversa com representantes de entidade esotérica para ajudar na crise energética (Folha de S.Paulo)

Ministério de Minas e Energia confirma reunião com equipe de Fundação Cacique Cobra Coral

17.out.2021 às 17h02; Atualizado: 17.out.2021 às 19h35


O Ministério de Minas e Energia reuniu-se recentemente com representantes da Fundação Cacique Cobra Coral para tratar da questão da crise hídrica que secou reservatórios de hidrelétricas do país neste ano. A reunião foi divulgada pela revista Veja na sexta-feira (15).

A pasta confirmou a reunião com representantes da entidade esotérica, a quem é atribuída poderes de intervenção no clima, em comunicado divulgado à imprensa neste domingo (17), que responde reportagens publicadas sobre o encontro.

Segundo o comunicado, que não cita quando a reunião foi realizada, o encontro não foi pedido pelo ministério, mas ocorreu em atendimento a “princípios da transparência e do diálogo franco”.

O ministério, que diz receber centenas de pedidos de audiência, afirmou que apenas aceitou o encontro com representantes da entidade e reproduziu email recebido no início de setembro em que representante da entidade chamado Osmar Santos pediu uma reunião com o ministro Bento Albuquerque.

O assunto da reunião seria “tratar da tragédia econômica x energética… e os meios para recuperar tais precipitações irregulares no lugar certo ainda na estação inverno que se finda e primavera”, segundo a mensagem reproduzida pelo comunicado do ministério, que ressalta que Albuquerque não participou da reunião.

“Durante a audiência, o senhor Osmar (diretor de relações governamentais do instituto) relatou aos técnicos do MME que o instituto faz serviços de previsões dos mais variados tipos”, afirmou a pasta. “Como servidores públicos, os servidores do MME apenas e tão somente ouviram as informações do senhor Osmar”, acrescentou o ministério.

Na semana passada, o Operador Nacional do Sistema Elétrico (ONS) afirmou que a projeção para o nível das represas de hidrelétricas do país é que eles cheguem até o fim do mês com 16,7% da sua capacidade na região Sudeste/Centro-Oeste, contra projeção de 15,2% feita na semana anterior.

O ONS afirmou ainda que vê ainda um cenário “bastante preocupante” para 2022 e recomendou que o país permaneça mobilizado para enfrentar a próxima estação seca.

Byung-Chul Han: smartphone e o “inferno dos iguais” (Outras Palavras)

Por Byung-Chul Han, em entrevista a Sergio C. Fanjul, no El País

Com certa vertigem, o mundo material, feito de átomos e moléculas, de coisas que podemos tocar e cheirar, está se dissolvendo em um mundo de informação, de não-coisas, como observa o filósofo alemão de origem coreana Byung-Chul Han. Não-coisas que, ainda assim, continuamos desejando, comprando e vendendo, que continuam nos influenciando. O mundo digital cada vez se hibridiza de modo mais notório com o que ainda consideramos mundo real, ao ponto de confundirem-se entre si, fazendo a existência cada vez mais intangível e fugaz. O último livro do pensador, Não-coisas. Quebras no mundo de hoje, se une a uma série de pequenos ensaios em que o pensador sucesso de vendas (o chamaram de rockstar da filosofia) disseca minuciosamente as ansiedades que o capitalismo neoliberal nos produz.

Unindo citações frequentes aos grandes filósofos e elementos da cultura popular, os textos de Han transitam do que chamou de “a sociedade do cansaço”, em que vivemos esgotados e deprimidos pelas inapeláveis exigências da existência, à análise das novas formas de entretenimento que nos oferecem. Da psicopolítica, que faz com que as pessoas aceitem se render mansamente à sedução do sistema, ao desaparecimento do erotismo que Han credita ao narcisismo e exibicionismo atual, que proliferam, por exemplo, nas redes sociais: a obsessão por si mesmo faz com que os outros desapareçam e o mundo seja um reflexo de nossa pessoa. O pensador reivindica a recuperação do contato íntimo com a cotidianidade – de fato, é sabido que ele gosta de cultivar lentamente um jardim, trabalhos manuais, o silêncio. E se rebela contra “o desaparecimento dos rituais” que faz com que a comunidade desapareça e que nos transformemos em indivíduos perdidos em sociedades doentes e cruéis.

Byung-Chul Han aceitou esta entrevista como EL PAÍS, mas somente mediante um questionário por e-mail que foi respondido em alemão pelo filósofo e posteriormente traduzido e editado.

PERGUNTA. Como é possível que em um mundo obcecado pela hiperprodução eo hiperconsumo, ao mesmo tempo os objetos vão se dissolvendo e vamos rumo a um mundo de não-coisas?

RESPOSTA. Há, sem dúvida, uma hiperinflação de objetos que conduz a sua proliferação explosiva. Mas se trata de objetos descartáveis com os quais não estabelecemos laços afetivos. Hoje estamos obcecados não com as coisas, e sim com informações e dados, ou seja, não-coisas. Hoje somos todos infômanos. Chegou a se falar de datasexuais [pessoas que compilam e compartilham obsessivamente informação sobre sua vida pessoal].

P. Nesse mundo que o senhor descreve, de hiperconsumo e perda de laços, por que é importante ter “coisas queridas” e estabelecer rituais?

R. As coisas são os apoios que dão tranquilidade na vida. Hoje em dia estão em conjunto obscurecidas pelas informações. O smartphone não é uma coisa. Eu o caracterizo como o infômata que produz e processa informações. As informações são todo o contrário aos apoios que dão tranquilidade à vida. Vivem do estímulo da surpresa. Elas nos submergem em um turbilhão de atualidade. Também os rituais, como arquiteturas temporais, dão estabilidade à vida. A pandemia destruiu essas estruturas temporais. Pense no teletrabalho. Quando o tempo perde sua estrutura, a depressão começa a nos afetar.

P. Em seu livro se estabelece que, pela digitalização, nos transformaremos em homo ludens, focados mais no lazer do que no trabalho. Mas, com a precarização e a destruição do emprego, todos poderemos ter acesso a essa condição?

R. Falei de um desemprego digital que não é determinado pela conjuntura. A digitalização levará a um desemprego maciço. Esse desemprego representará um problema muito sério no futuro. O futuro humano consistirá na renda básica e nos jogos de computador? Um panorama desalentador. Com panem et circenses (pão e circo) Juvenal se refere à sociedade romana em que a ação política não é possível. As pessoas se mantêm contentes com alimentos gratuitos e jogos espetaculares. A dominação total é aquela em que as pessoas só se dedicam a jogar. A recente e hiperbólica série coreana da Netflix, Round 6, em que todo mundo só se dedica ao jogo, aponta nessa direção.

P. Em que sentido?

R. Essas pessoas estão totalmente endividadas e se entregam a esse jogo mortal que promete ganhos enormes. Round 6 representa um aspecto central do capitalismo em um formato extremo. Walter Benjamin já disse que o capitalismo representa o primeiro caso de um culto que não é expiatório, e sim nos endivida. No começo da digitalização se sonhava que ela substituiria o trabalho pelo jogo. Na verdade, o capitalismo digital explora impiedosamente a pulsão humana pelo jogo. Pense nas redes sociais, que incorporam elementos lúdicos para provocar o vício nos usuários.

P. De fato, o smatphone nos prometia certa liberdade… Não se transformou em uma longa corrente que nos aprisiona onde quer que estejamos?

R. O smartphone é hoje um lugar de trabalho digital e um confessionário digital. Todo dispositivo, toda técnica de dominação gera artigos cultuados que são utilizados à subjugação. É assim que a dominação se consolida. O smartphone é o artigo de culto da dominação digital. Como aparelho de subjugação age como um rosário e suas contas; é assim que mantemos o celular constantemente nas mãos. O like é o amém digital. Continuamos nos confessando. Por decisão própria, nos desnudamos. Mas não pedimos perdão, e sim que prestem atenção em nós.

P. Há quem tema que a internet das coisas possa significar algo assim como a rebelião dos objetos contra o ser humano.

R. Não exatamente. A smarthome [casa inteligente] com coisas interconectadas representa uma prisão digital. A smartbed [cama inteligente] com sensores prolonga a vigilância também durante as horas de sono. A vigilância vai se impondo de maneira crescente e sub-reptícia na vida cotidiana como se fosse o conveniente. As coisas informatizadas, ou seja, os infômatas, se revelam como informadores eficientes que nos controlam e dirigem constantemente.

P. O senhor descreveu como o trabalho vai ganhando caráter de jogo, as redes sociais, paradoxalmente, nos fazem sentir mais livres, o capitalismo nos seduz. O sistema conseguiu se meter dentro de nós para nos dominar de uma maneira até prazerosa para nós mesmos?

R. Somente um regime repressivo provoca a resistência. Pelo contrário, o regime neoliberal, que não oprime a liberdade, e sim a explora, não enfrenta nenhuma resistência. Não é repressor, e sim sedutor. A dominação se torna completa no momento em que se apresenta como a liberdade.

P. Por que, apesar da precariedade e da desigualdade crescentes, dos riscos existenciais etc., o mundo cotidiano nos países ocidentais parece tão bonito, hiperplanejado, e otimista? Por que não parece um filme distópico e cyberpunk?

R. O romance 1984 de George Orwell se transformou há pouco tempo em um sucesso de vendas mundial. As pessoas têm a sensação de que algo não anda bem com nossa zona de conforto digital. Mas nossa sociedade se parece mais a Admirável Mundo Novo de Aldous Huxley. Em 1984 as pessoas são controladas pela ameaça de machucá-las. Em Admirável Mundo Novo são controladas pela administração de prazer. O Estado distribui uma droga chamada “soma” para que todo mundo se sinta feliz. Esse é nosso futuro.

P. O senhor sugere que a Inteligência Artificial e o big data não são formas de conhecimento tão espantosas como nos fazem crer, e sim mais “rudimentares”. Por que?

R. O big data dispõe somente de uma forma muito primitiva de conhecimento, a saber, a correlação: acontece A, então ocorre B. Não há nenhuma compreensão. A Inteligência Artificial não pensa. A Inteligência Artificial não sente medo.

P. Blaise Pascal disse que a grande tragédia do ser humano é que não pode ficar quieto sem fazer nada. Vivemos em um culto à produtividade, até mesmo nesse tempo que chamamos “livre”. O senhor o chamou, com grande sucesso, de a sociedade do cansaço. Nós deveríamos nos fixar na recuperação do próprio tempo como um objetivo político?

R. A existência humana hoje está totalmente absorvida pela atividade. Com isso se faz completamente explorável. A inatividade volta a aparecer no sistema capitalista de dominação com incorporação de algo externo. É chamado tempo de ócio. Como serve para se recuperar do trabalho, permanece vinculado ao mesmo. Como derivada do trabalho constitui um elemento funcional dentro da produção. Precisamos de uma política da inatividade. Isso poderia servir para liberar o tempo das obrigações da produção e tornar possível um tempo de ócio verdadeiro.

P. Como se combina uma sociedade que tenta nos homogeneizar e eliminar as diferenças, com a crescente vontade das pessoas em ser diferentes dos outros, de certo modo, únicas?

R. Todo mundo hoje quer ser autêntico, ou seja, diferente dos outros. Dessa forma, estamos nos comparando o tempo todo com os outros. É justamente essa comparação que nos faz todos iguais. Ou seja: a obrigação de ser autênticos leva ao inferno dos iguais.

P. Precisamos de mais silêncio? Ficar mais dispostos a escutar o outro?

R. Precisamos que a informação se cale. Caso contrário, explorará nosso cérebro. Hoje entendemos o mundo através das informações. Assim a vivência presencial se perde. Nós nos desconectamos do mundo de modo crescente. Vamos perdendo o mundo. O mundo é mais do que a informação. A tela é uma representação pobre do mundo. Giramos em círculo ao redor de nós mesmos. O smartphone contribui decisivamente a essa percepção pobre de mundo. Um sintoma fundamental da depressão é a ausência de mundo.

P. A depressão é um dos mais alarmantes problemas de saúde contemporâneos. Como essa ausência do mundo opera?

R. Na depressão perdemos a relação com o mundo, com o outro. E nos afundamos em um ego difuso. Penso que a digitalização, e com ela o smartphone, nos transformam em depressivos. Há histórias de dentistas que contam que seus pacientes se aferram aos seus telefones quando o tratamento é doloroso. Por que o fazem? Graças ao celular sou consciente de mim mesmo. O celular me ajuda a ter a certeza de que vivo, de que existo. Dessa forma nos aferramos ao celular em situações críticas, como o tratamento dental. Eu lembro que quando era criança apertava a mão de minha mãe no dentista. Hoje a mãe não dá a mão à criança, e sim o celular para que se agarre a ele. A sustentação não vem dos outros, e sim de si mesmo. Isso nos adoece. Temos que recuperar o outro.

P. Segundo o filósofo Fredric Jameson é mais fácil imaginar o fim do mundo do que o fim do capitalismo. O senhor imaginou algum modo de pós-capitalismo agora que o sistema parece em decadência?

R. O capitalismo corresponde realmente às estruturas instintivas do homem. Mas o homem não é só um ser instintivo. Temos que domar, civilizar e humanizar o capitalismo. Isso também é possível. A economia social de mercado é uma demonstração. Mas nossa economia está entrando em uma nova época, a época da sustentabilidade.

P. O senhor se doutorou com uma tese sobre Heidegger, que explorou as formas mais abstratas de pensamento e cujos textos são muito obscuros até o profano. O senhor, entretanto, consegue aplicar esse pensamento abstrato a assuntos que qualquer um pode experimentar. A filosofia deve se ocupar mais do mundo em que a maior parte da população vive?

R. Michel Foucault define a filosofia como uma espécie de jornalismo radical, e se considera a si mesmo jornalista. Os filósofos deveriam se ocupar sem rodeios do hoje, da atualidade. Nisso sigo Foucault. Eu tento interpretar o hoje em pensamentos. Esses pensamentos são justamente o que nos fazem livres.

Trust in meteorology has saved lives. The same is possible for climate science. (Washington Post)

Placing our faith in forecasting and science could save lives and money

Oliver Uberti

October 14, 2021


2021 is shaping up to be a historically busy hurricane season. And while damage and destruction have been serious, there has been one saving grace — that the National Weather Service has been mostly correct in its predictions.

Thanks to remote sensing, Gulf Coast residents knew to prepare for the “life-threatening inundation,” “urban flooding” and “potentially catastrophic wind damage” that the Weather Service predicted for Hurricane Ida. Meteorologists nailed Ida’s strength, surge and location of landfall while anticipating that a warm eddy would make her intensify too quickly to evacuate New Orleans safely. Then, as her remnants swirled northeast, reports warned of tornadoes and torrential rain. Millions took heed, and lives were saved. While many people died, their deaths resulted from failures of infrastructure and policy, not forecasting.

The long history of weather forecasting and weather mapping shows that having access to good data can help us make better choices in our own lives. Trust in meteorology has made our communities, commutes and commerce safer — and the same is possible for climate science.

Two hundred years ago, the few who studied weather deemed any atmospheric phenomenon a “meteor.” The term, referencing Aristotle’s “Meteorologica,” essentially meant “strange thing in the sky.” There were wet things (hail), windy things (tornadoes), luminous things (auroras) and fiery things (comets). In fact, the naturalist Elias Loomis, who was among the first to spot Halley’s comet upon its return in 1835, thought storms behaved as cyclically as comets. So to understand “the laws of storms,” Loomis and the era’s other leading weatherheads began gathering observations. Master the elements, they reasoned, and you could safely sail the seas, settle the American West, plant crops with confidence and ward off disease.

In 1856, Joseph Henry, the Smithsonian Institution’s first director, hung a map of the United States in the lobby of its Washington headquarters. Every morning, he would affix small colored discs to show the nation’s weather: white for places with clear skies, blue for snow, black for rain and brown for cloud cover. An arrow on each disc allowed him to note wind direction, too. For the first time, visitors could see weather across the expanding country.

Although simple by today’s standards, the map belied the effort and expense needed to select the correct colors each day. Henry persuaded telegraph companies to transmit weather reports every morning at 10. Then he equipped each station with thermometers, barometers, weathervanes and rain gauges — no small task by horse and rail, as instruments often broke in transit.

For longer-term studies of the North American climate, Henry enlisted academics, farmers and volunteers from Maine to the Caribbean. Eager to contribute, “Smithsonian observers” took readings three times a day and posted them to Washington each month. At its peak in 1860, the Smithsonian Meteorological Project had more than 500 observers. Then the Civil War broke out.

Henry’s ranks thinned by 40 percent as men traded barometers for bayonets. Severed telegraph lines and the priority of war messages crippled his network. Then in January 1865, a fire in Henry’s office landed the fatal blow to the project. All of his efforts turned to salvaging what survived. With a vacuum of leadership in Washington, citizen scientists picked up the slack.

Although the Chicago Tribune lampooned Lapham, wondering “what practical value” a warning service would provide “if it takes 10 years to calculate the progress of a storm,” Rep. Halbert E. Paine (Wis.), who had studied storms under Loomis, rushed a bill into Congress before the winter recess. In early 1870, a joint resolution establishing a storm-warning service under the U.S. Army Signal Office passed without debate. President Ulysses S. Grant signed it into law the following week.

Despite the mandate for an early-warning system, an aversion to predictions remained. Fiscal hawks could not justify an investment in erroneous forecasts, religious zealots could not stomach the hubris, and politicians wary of a skeptical public could not bear the fallout. In 1893, Agriculture Secretary J. Sterling Morton cut the salary of one of the country’s top weather scientists, Cleveland Abbe, by 25 percent, making an example out of him.

While Moore didn’t face consequences for his dereliction of duty, the Weather Bureau’s hurricane-forecasting methods gradually improved as the network expanded and technologies like radio emerged. The advent of aviation increased insight into the upper atmosphere; military research led to civilian weather radar, first deployed at Washington National Airport in 1947. By the 1950s, computers were ushering in the future of numerical forecasting. Meanwhile, public skepticism thawed as more people and businesses saw it in their best interests to trust experts.

In September 1961, a local news team decided to broadcast live from the Weather Bureau office in Galveston, Tex., as Hurricane Carla angled across the Gulf of Mexico. Leading the coverage was a young reporter named Dan Rather. “There is the eye of the hurricane right there,” he told his audience as the radar sweep brought the invisible into view. At the time, no one had seen a radar weather map televised before.

Rather realized that for viewers to comprehend the storm’s size, location and imminent danger, people needed a sense of scale. So he had a meteorologist draw the Texas coast on a transparent sheet of plastic, which Rather laid over the radarscope. Years later, he recalled that when he said “one inch equals 50 miles,” you could hear people in the studio gasp. The sight of the approaching buzz saw persuaded 350,000 Texans to evacuate their homes in what was then the largest weather-related evacuation in U.S. history. Ultimately, Carla inflicted twice as much damage as the Galveston hurricane 60 years earlier. But with the aid of Rather’s impromptu visualization, fewer than 50 lives were lost.

In other words, weather forecasting wasn’t only about good science, but about good communication and visuals.

Data visualization helped the public better understand the weather shaping their lives, and this enabled them to take action. It also gives us the power to see deadly storms not as freak occurrences, but as part of something else: a pattern.

Two hundred years ago, a 10-day forecast would have seemed preposterous. Now we can predict if we’ll need an umbrella tomorrow or a snowplow next week. Imagine if we planned careers, bought homes, built infrastructure and passed policy based on 50-year forecasts as routinely as we plan our weeks by five-day ones.

Unlike our predecessors of the 19th or even 20th centuries, we have access to ample climate data and data visualization that give us the knowledge to take bold actions. What we do with that knowledge is a matter of political will. It may be too late to stop the coming storm, but we still have time to board our windows.

Geoengineering: We should not play dice with the planet (The Hill)

Kim Cobb and Michael E. Mann, opinion contributors

10/12/21 11:30 AM EDT


The fate of the Biden administration’s agenda on climate remains uncertain, captive to today’s toxic atmosphere in Washington, DC. But the headlines of 2021 leave little in the way of ambiguity — the era of dangerous climate change is already upon us, in the form of wildfires, hurricanes, droughts and flooding that have upended lives across America. A recent UN report on climate is clear these impacts will worsen in the coming two decades if we fail to halt the continued accumulation of greenhouse gases in the atmosphere.

To avert disaster, we must chart a different climate course, beginning this year, to achieve steep emissions reductions this decade. Meeting this moment demands an all hands-on-deck approach. And no stone should be left unturned in our quest for meaningful options for decarbonizing our economy.

But while it is tempting to pin our hopes on future technology that might reduce the scope of future climate damages, we must pursue such strategies based on sound science, with a keen eye for potential false leads and dead ends. And we must not allow ourselves to be distracted from the task at hand — reducing fossil fuel emissions — by technofixes that at best, may not pan out, and at worst, may open the door to potentially disastrous unintended consequences. 

So-called “geoengineering,” the intentional manipulation of our planetary environment in a dubious effort to offset the warming from carbon pollution, is the poster child for such potentially dangerous gambits. As the threat of climate change becomes more apparent, an increasingly desperate public — and the policymakers that represent them — seem to be willing to entertain geoengineering schemes. And some prominent individuals, such as former Microsoft CEO Bill Gates, have been willing to use them to advocate for this risky path forward.  

The New York Times recently injected momentum into the push for geoengineering strategies with a recent op-ed by Harvard scientist and geoengineering advocate David Keith. Keith argues that even in a world where emissions cuts are quick enough and large enough to limit warming to 1.5 degrees Celsius by 2050, we would face centuries of elevated atmospheric CO2 concentrations and global temperatures combined with rising sea levels.

The solution proposed by geoengineering proponents? A combination of slow but steady CO2 removal factories (including Keith’s own for-profit company) and a quick-acting temperature fix — likened to a “band-aid” — delivered by a fleet of airplanes dumping vast quantities of chemicals into the upper atmosphere.

This latter scheme is sometimes called “solar geoengineering” or “solar radiation management,” but that’s really a euphemism for efforts to inject potentially harmful chemicals into the stratosphere with potentially disastrous side effects, including more widespread drought, reduced agricultural productivity, and unpredictable shifts in regional climate patterns. Solar geoengineering does nothing to slow the pace of ocean acidification, which will increase with emissions.

On top of that is the risk of “termination shock” (a scenario in which we suffer the cumulative warming from decades of increasing emissions in a matter of several years, should we abruptly end solar geoengineering efforts). Herein lies the moral hazard of this scheme: It could well be used to justify delays in reducing carbon emissions, addicting human civilization writ large to these dangerous regular chemical injections into the atmosphere. 

While this is the time to apply bold, creative thinking to accelerate progress toward climate stability, this is not the time to play fast and loose with the planet, in service of any agenda, be it political or scientific in nature. As the recent UN climate report makes clear, any emissions trajectory consistent with peak warming of 1.5 degrees Celsius by mid-century will pave the way for substantial drawdown of atmospheric CO2 thereafter. Such drawdown prevents further increases in surface temperatures once net emissions decline to zero, followed by global-scale cooling shortly after emissions go negative.

Natural carbon sinks — over land as well as the ocean — play a critical role in this scenario. They have sequestered half of our historic CO2 emissions, and are projected to continue to do so in coming decades. Their buffering capacity may be reduced with further warming, however, which is yet another reason to limit warming to 1.5 degrees Celsius this century. But if we are to achieve negative emissions this century — manifest as steady reductions of atmospheric CO2 concentrations — it will be because we reduce emissions below the level of uptake by natural carbon sinks. So, carbon removal technology trumpeted as a scalable solution to our emissions challenge is unlikely to make a meaningful dent in atmospheric CO2 concentrations.

As to the issue of climate reversibility, it’s naïve to think that we could reverse nearly two centuries of cumulative emissions and associated warming in a matter of decades. Nonetheless, the latest science tells us that surface warming responds immediately to reductions in carbon emissions. Land responds the fastest, so we can expect a rapid halt to the worsening of heatwaves, droughts, wildfires and floods once we reach net-zero emissions. Climate impacts tied to the ocean, such as marine heat waves and hurricanes, would respond somewhat more slowly. And the polar ice sheets may continue to lose mass and contribute to sea-level rise for centuries, but coastal communities can more easily adapt to sea-level rise if warming is limited to 1.5 degrees Celsius. 

While it’s appealing to think that a climate “band-aid” could protect us from the worst climate impacts, solar geoengineering is more like risky elective surgery than a preventative medicine. This supposed “climate fix” might very well be worse than the disease, drying the continents and reducing crop yields, and having potentially other unforeseen negative consequences. The notion that such an intervention might somehow aid the plight of the global poor seems misguided at best.

When considering how to advance climate justice in the world, it is critical to ask, “Who wins — and who loses?” in a geoengineered future. If the winners are petrostates and large corporations who, if history is any guide, will likely be granted preferred access to the planetary thermostat, and the losers are the global poor — who already suffer disproportionately from dirty fossil fuels and climate impacts — then we might simply be adding insult to injury.

To be clear, the world should continue to invest in research and development of science and technology that might hasten societal decarbonization and climate stabilization, and eventually the return to a cooler climate. But those technologies must be measured, in both efficacy and safety, against the least risky and most surefire path to a net-zero world: the path from a fossil fuel-driven to a clean energy-driven society.

Physics meets democracy in this modeling study (Science Daily)

A new paper explores how the opinions of an electorate may be reflected in a mathematical model ‘inspired by models of simple magnetic systems’

Summary: A study leverages concepts from physics to model how campaign strategies influence the opinions of an electorate in a two-party system.


A study in the journal Physica A leverages concepts from physics to model how campaign strategies influence the opinions of an electorate in a two-party system.

Researchers created a numerical model that describes how external influences, modeled as a random field, shift the views of potential voters as they interact with each other in different political environments.

The model accounts for the behavior of conformists (people whose views align with the views of the majority in a social network); contrarians (people whose views oppose the views of the majority); and inflexibles (people who will not change their opinions).

“The interplay between these behaviors allows us to create electorates with diverse behaviors interacting in environments with different levels of dominance by political parties,” says first author Mukesh Tiwari, PhD, associate professor at the Dhirubhai Ambani Institute of Information and Communication Technology.

“We are able to model the behavior and conflicts of democracies, and capture different types of behavior that we see in elections,” says senior author Surajit Sen, PhD, professor of physics in the University at Buffalo College of Arts and Sciences.

Sen and Tiwari conducted the study with Xiguang Yang, a former UB physics student. Jacob Neiheisel, PhD, associate professor of political science at UB, provided feedback to the team, but was not an author of the research. The study was published online in Physica A in July and will appear in the journal’s Nov. 15 volume.

The model described in the paper has broad similarities to the random field Ising model, and “is inspired by models of simple magnetic systems,” Sen says.

The team used this model to explore a variety of scenarios involving different types of political environments and electorates.

Among key findings, as the authors write in the abstract: “In an electorate with only conformist agents, short-duration high-impact campaigns are highly effective. … In electorates with both conformist and contrarian agents and varying level(s) of dominance due to local factors, short-term campaigns are effective only in the case of fragile dominance of a single party. Strong local dominance is relatively difficult to influence and long-term campaigns with strategies aimed to impact local level politics are seen to be more effective.”

“I think it’s exciting that physicists are thinking about social dynamics. I love the big tent,” Neiheisel says, noting that one advantage of modeling is that it could enable researchers to explore how opinions might change over many election cycles — the type of longitudinal data that’s very difficult to collect.

Mathematical modeling has some limitations: “The real world is messy, and I think we should embrace that to the extent that we can, and models don’t capture all of this messiness,” Neiheisel says.

But Neiheisel was excited when the physicists approached him to talk about the new paper. He says the model provides “an interesting window” into processes associated with opinion dynamics and campaign effects, accurately capturing a number of effects in a “neat way.”

“The complex dynamics of strongly interacting, nonlinear and disordered systems have been a topic of interest for a long time,” Tiwari says. “There is a lot of merit in studying social systems through mathematical and computational models. These models provide insight into short- and long-term behavior. However, such endeavors can only be successful when social scientists and physicists come together to collaborate.”

One policy accounts for a lot of the decarbonisation in Joe Biden’s climate plans (The Economist)

As Democrats trim the legislation, they should focus on keeping it

Oct 12th 2021


TAKE A ROAD TRIP to Indianapolis, home to a certain two-and-a-half-mile race track, and you will find yourself in good company. A survey carried out before the pandemic found that about 85% of local commuters drive to work, alone. Standing on a bridge over 38th Street, which runs by the state fairground, you cannot escape the roar of six lanes of petrol-fired traffic below—and, reports a local, this is quiet compared with the noise on pre-virus days. Getting Americans to kick their addiction to fossil fuels will require many of these drivers to find another way of getting to work, and to move on from the flaming hydrocarbons celebrated at the city’s famous oval.

Joe Biden hopes to use what looks like a narrow window of Democratic control of Congress to encourage this transition. The last time lawmakers came close to writing climate legislation on anything like this scale was in 2009, when the Waxman-Markey bill, which would have established a trading system for greenhouse-gas emissions, was passed by the House. Since then, a Democratic White House has tried to nudge America to reduce emissions, by issuing new regulations, and a Republican White House has tried to undo them. That record illustrates what a delicate operation this is. Yet despite having a much weaker grip on Congress than Barack Obama had in the first year of his presidency, Mr Biden and his legislative allies have put forward a sweeping set of proposals for decarbonising America’s economy. These would promote everything from clean energy on the grid and electric vehicles on the road, to union jobs making green technologies and climate justice for left-behind communities.

Were this wish list passed in its entirety, which is unlikely, it would give a boost to Mr Biden’s pledge to reduce America’s emissions by roughly half from their 2005 level by 2030. A chart released by the office of Chuck Schumer, the Senate’s majority leader, suggests that implementing all of these provisions could reduce America’s emissions by 45% below 2005 levels by 2030, thus achieving almost all of Mr Biden’s goal of cutting them by roughly half in that period (see chart 1). Passing a law, even a less expansive one, would allow Mr Biden to travel to the UN climate summit in Glasgow in November representing a country that is making progress towards internationally agreed goals, rather than asking for the patience of poorer, less technologically sophisticated countries while America sorts itself out.

Some of the Democratic proposals are in a $1trn infrastructure bill with bipartisan support. But most are found in a $3.5trn budget bill that, on account of Senate rules, can only pass through a partisan parliamentary manoeuvre known as reconciliation. This requires the assent of all 50 Democratic senators. The likeliest outcome is a compromise between Democratic progressives and moderates that yokes together the agreed infrastructure bill with a much slimmer version of the $3.5trn proposal. Yet it is possible that neither bill will become law.

This raises two questions. First, how good on climate can a salami-sliced version of Mr Biden’s agenda, the result of a negotiation between 270 Democratic members of Congress each angling for their constituents’ interests, really be? Second, how bad would it be for America’s decarbonisation efforts were both bills to fail?

Happily even reconciliation-lite could bring meaningful progress if key bits of the current proposals survive the negotiations. Paul Bledsoe of the Progressive Policy Institute, a think-tank, is confident a deal “likely a bit under $2trn” will happen this month. The Rhodium Group, an analysis firm, reckons that just six proposals would cut America’s emissions by nearly 1bn tonnes in 2030 compared with no new policies (see chart 2), about a sixth of America’s total net emissions per year. That is roughly equivalent to the annual emissions from all cars and pickup trucks on American roads, or the emissions of Florida and Texas combined. The six include proposals related to “natural carbon removal” (which involves spending on forests and soil), fossil fuels (making it more expensive to emit methane) and transport (a generous credit for buyers of electric vehicles).

The big prize, though, is the power sector. Two proposals for decarbonising the grid account for the lion’s share of likely emissions reductions: a new Clean Electricity Performance Programme (CEPP) and more mundane reforms to the tax credits received by clean energy. The CEPP has been touted by Mr Biden’s cabinet officials and leading progressives as a linchpin of the climate effort. It is loosely based on the mandatory clean electricity standards imposed by over two dozen states which have successfully boosted adoption of low-carbon energy.

The CEPP is flawed in a couple of ways, though. Because it has to be primarily a fiscal measure in order to squeeze through the reconciliation process it does not involve mandatory regulation, unlike those successful state energy standards. Rather, it uses (biggish) subsidies and (rather punier) penalty fees to try to nudge utilities to build more clean energy. It is politically vulnerable because it is seen as unfriendly to natural gas and coal (unless they have expensive add-on kit to capture and store related emissions). That has incurred the hostility of Senator Joe Manchin, a Democrat who represents coal-rich West Virginia, without whose approval the bill will fail. Some influential utility companies with coal assets, including Ohio-based American Electric Power, do not like it either.

Despite the attention paid to it, CEPP is actually less potent as a greenhouse-gas slayer than those boring tax credits, which are less controversial because they do not overtly penalise coal or gas. Two energy veterans, one at a top renewables lobbying outfit and the other at a fossil-heavy utility, agree that the tax credits would sharply boost investment in low-carbon technologies. That is because they improve the current set-up by replacing stop-go uncertainty with a predictable long-term tax regime, and make tax breaks “refundable” rather than needing to be offset against tax liabilities, meaning even utilities that do not have such tax liabilities can enjoy them as freely as cash in the bank.

Thus the obsession over the CEPP is overshadowing the real star proposal. The tax credits have “a huge impact potentially”, reckons Rhodium, accounting for over one-quarter of the greenhouse-gas emissions reductions in the legislation, at a cost of roughly $150bn over ten years. A former administrator of the Environmental Protection Agency (EPA) puts it bluntly: “Take the wind and solar tax credits at ten years if you had to choose—and let everything else go.”

What if Democrats fail, the negotiations fall apart and Mr Biden is left empty handed? That would be embarrassing. And it would perhaps make it difficult to pursue ambitious federal climate policies through Congress for years, just as the failure of Waxman-Markey in 2009 haunted lawmakers. However it would not mean America can do nothing at all about climate change.
First of all, as Mr Biden’s officials have already made clear, they stand ready to use regulations to push ahead on decarbonisation efforts, just as the Obama administration did. Last month the EPA issued rules cracking-down on emissions of hydrofluorocarbons, an especially powerful greenhouse gas. The administration also has plans for loan guarantees for energy innovations and for speeding-up approvals for offshore wind farms. Yet this is tinkering compared with the federal law being discussed, especially as new regulations will likely encounter legal challenges.

Even if the federal government fails again, states and cities have climate policies too. Drawing on analysis funded by Bloomberg Philanthropies, Leon Clarke of the University of Maryland calculates that decentralised policies emulating the current best efforts of states like California could achieve roughly one-quarter of Mr Biden’s objective. But this is a bad deal: such efforts would fall a long way short of the federal proposal in terms of emissions reduction, and what reductions they achieve would be more expensive than if done at the federal level. Still, it is not nothing. Last month, Illinois passed the country’s boldest climate-change law. Democratic states such as New York and California have green policies, but Republican states such as Texas and Indiana have big wind industries too.

While Mr Clarke says Congress has to act if America is to achieve Mr Biden’s targets, he believes that progress will continue even if Congress falters, because there is now a deeper sense of ownership of climate policy among local and state governments. “The Trump years really changed the way that subnationals in the US view climate action,” he says. “They can’t rely on the federal government.”

Change is happening in surprising places. Take that flyover in Indianapolis. The city’s officials have made it into a bike path that will be connected to 55 miles of commuter-friendly trails traversing the city. $100m has been allocated for building a bus-rapid transit system, which is a cheap and efficient substitute for underground rail, with more such rapid bus lines on the cards. Bloated 38th Street will undergo a “lane diet” with car and lorry traffic yielding two lanes to the buses. Come back in a few years and the view from the bridge will be quieter.

The Death of the Bering Strait Theory (Indian Country Today)

Updated: Sep 13, 2018. Original: Aug 12, 2016

Two new studies have finally put an end to the theory that the Americas were populated by ancient peoples who walked across the Bering Strait.

Two new studies have now, finally, put an end to the long-held theory that the Americas were populated by ancient peoples who walked across the Bering Strait land-bridge from Asia approximately 15,000 years ago. Because much of Canada was then under a sheet of ice, it had long been hypothesised that an “ice-free corridor” might have allowed small groups through from Beringia, some of which was ice-free. One study published in the journal Nature, entitled “Postglacial Viability and Colonization in North America’s Ice-Free Corridor” found that the corridor was incapable of sustaining human life until about 12,600 years ago, or well after the continent had already been settled.

An international team of researchers “obtained radiocarbon dates, pollen, macrofossils and metagenomic DNA from lake sediment cores” from nine former lake beds in British Columbia, where the Laurentide and Cordellian ice sheets split apart. Using a technique called “shotgun sequencing,” the team had to sequence every bit of DNA in a clump of organic matter in order to distinguish between the jumbled strands of DNA. They then matched the results to a database of known genomes to differentiate the organisms. Using this data they reconstructed how and when different flora and fauna emerged from the once ice-covered landscape. According to Mikkel Pedersen, a Ph.D. student at the Center for Geogenetics, University of Copenhagen, in the deepest layers, from 13,000 years ago, “the land was completely naked and barren.”

“What nobody has looked at is when the corridor became biologically viable,” noted study co-author, Professor Eske Willerslev, an evolutionary geneticist at the Centre for GeoGenetics and also the Department of Zoology, the University of Cambridge. “The bottom line is that even though the physical corridor was open by 13,000 years ago, it was several hundred years before it was possible to use it.” In Willerslev’s view, “that means that the first people entering what is now the U.S., Central and South America must have taken a different route.”

A second study, “Bison Phylogeography Constrains Dispersal and Viability of the Ice Free Corridor in Western Canada,” published in the Proceedings of the National Academy of Sciences, examined ancient mitochondrial DNA from bison fossils to “determine the chronology for when the corridor was open and viable for biotic dispersals” and found that the corridor was potentially a viable route for bison to travel through about 13,000 years ago, or slightly earlier than the Nature study.

Geologists had long known that the towering icecaps were a formidable barrier to migration from Asia to the Americas between 26,000 to 10,000 years ago. Thus the discovery in 1932 of the Clovis spear points, believed at that time to be about 10,000 years old, presented a problem, given the overwhelming presumption of the day that the ancient Indians had walked over from Asia about that time. In 1933, the Canadian geologist William Alfred Johnston proposed that when the glaciers began melting, they broke into two massive sheets long before completely disappearing, and between these two ice sheets people might have been able to walk through, an idea dubbed the “ice-free corridor” by Swedish-American geologist Ernst Antevs two years later.

Archaeologists then seized on the idea of a passageway to uphold the tenuous notion that Indians had arrived to the continent relatively recently, until such belief became a matter of faith. Given the recent discoveries that place Indians in the Americas at least 14,000 years ago, both studies now finally lay to rest the ice-free corridor theory. As Willerslev points out, “The school book story that most of us are used to doesn’t seem to be supported.” The new school book story is that the Indians migrated in boats down along the Pacific coast around 15,000 years ago. How long that theory will hold up remains to be seen.
