Projeto da Ufersa levará conhecimento às escolas públicas do semiárido do Rio Grande do Norte

A Universidade Federal Rural do Semi-Árido (Ufersa) irá executar, a partir de fevereiro, o Projeto Ciência para Todos no Semi-Árido Potiguar. O projeto, que tem como coordenadora a professora Celicina Maria da Silveira Borges Azevedo, foi submetido aos ministérios da Ciência e Tecnologia e da Educação, com colaboração da Universidade do Estado do Rio Grande do Norte (Uern).

Já aprovado pelo Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq), o projeto objetiva despertar nos adolescentes de Escolas públicas de ensino médio do semiárido nordestino a curiosidade científica.

“A nossa proposta é treiná-los no uso da metodologia científica e realizar uma grande feira de ciências com, no mínimo, 100 projetos feitos pelos estudantes através do uso do método científico nas mais diversas áreas do conhecimento”, explica a professora Celicina Borges.

Ainda segundo a professora, a proposta foi concebida depois da experiência em projetos para a melhoria do ensino de ciências nas Escolas públicas da 12ª Diretoria Regional de Educação, Cultura e Desportos (Dired). Para possibilitar o aumento da experiência, a intenção é dar continuidade e ampliar o trabalho para outras Direds, como a 13ª, 14ª e 15ª.

Todas as 77 escolas de ensino médio dessas Direds serão contempladas. No total, 49 cidades, o que corresponde a 29% dos municípios do estado, todos na região do semiárido. O projeto tem custeio global de mais de R$ 190 mil.

A professora explica que o cronograma será dividido em cinco etapas. A primeira com a capacitação de professores, seguida de oficinas de construção de projetos e visitas de acompanhamento aos trabalhos desenvolvidos. A segunda será a realização, das Escolas, de suas próprias feiras de ciências e a escolha dos melhores projetos. A terceira etapa será a realização da feira de ciências a nível regional com os projetos selecionados na segunda etapa.

Por fim, as duas últimas etapas, em Mossoró, com a Semana de Ciência e Tecnologia, no mês de outubro, dando início a quarta etapa. A Feira Estadual terá a participação de todos os projetos selecionados nas feiras regionais das quatro Direds. A quinta e última etapa será a entrega das bolsas de Iniciação Científica Junior para os estudantes premiados, além da execução de um curso de Ciências para esses alunos.

No total, serão atribuídas 18 bolsas, onde dentre os critérios de escolha estão o uso do método científico, a criatividade e a relevância da pesquisa. A duração da bolsa será de 12 meses e, no final, os estudantes e professores premiados, bem como os coordenadores das Direds e a coordenadora geral do projeto receberão passagem aérea de ida e volta, para participação e apresentação dos projetos em Feira de Ciências de âmbito nacional.

Agência FAPESP – Apesar de estimar hoje com até 97% de acerto a probabilidade de chuvas nas próximas 24 horas, a previsão de tempo no Brasil ainda é incapaz de determinar com exatidão se temporais como os que castigaram São Paulo nesta semana voltarão a se repetir nos próximos dias com a mesma intensidade.

O problema se deve a limitações dos modelos meteorológicos (representações numéricas aproximadas do comportamento da atmosfera) utilizados até agora no País.

Mas, um supercomputador, que entrou em operação no início de janeiro no Centro de Previsão do Tempo e Estudos Climáticos (CPTEC), em Cachoeira Paulista (SP), promete possibilitar aprimorar esses modelos para que possam indicar com maior precisão e antecedência chuvas e fenômenos meteorológicos extremos, como tempestades, que estão se tornando comuns no País.

Batizado de Tupã – o deus do trovão na mitologia tupi-guarani – o supercomputador permitirá aos pesquisadores do CPTEC desenvolver e executar modelos meteorológicos mais sofisticados e com maior resolução espacial, que demandam mais memória e velocidade de processamento. E, dessa forma, melhorar gradativamente a qualidade das previsões meteorológicas de tempo e clima no Brasil.

“Fazer previsão de tempo no Brasil é bastante complicado. O País é muito grande, com clima e geografia muito variadas, o que dificulta muito fazer previsões detalhadas para sete dias, por exemplo”, disse Marcelo Enrique Seluchi, chefe de supercomputação do Inpe e coordenador substituto do CPTEC à Agência FAPESP.

De acordo com o pesquisador, hoje a previsão diária de tempo no País, que indica apenas se ocorrerá ou não chuvas nas próximas 24 horas, tem um nível de confiabilidade equiparável à realizada pelos maiores centros meteorológicos do mundo, atingindo quase 100% de acerto. Já as previsões de longo prazo – como as de uma semana ou 15 dias – têm menores índices de acerto, atingindo 80% no prazo de uma semana e reduzindo cerca de 3% a cada dia acrescentado.

Com o supercomputador, os pesquisadores do Inpe pretendem aumentar progressivamente a margem de acerto dessas previsões para fazer com que possam prever com pelo menos dois dias de antecedência temporais como os que atingiram as cidades de São Luiz do Paraitinga (SP) e Angra dos Reis (RJ) no início de 2010.

“Nós ganhamos um dia de previsão para cada dez anos de investimento na melhoria dos modelos meteorológicos. Isso pode parecer pouco, mas representa um ganho muito grande para termos a ideia da magnitude de um evento meteorológico extremo”, disse Seluchi.

Limitações

Segundo o cientista, uma das maiores limitações na previsão do tempo no Brasil hoje é a resolução espacial e temporal relativamente baixa dos modelos meteorológicos numéricos utilizados.

A resolução espacial dos modelos usados hoje para prever tempestades, por exemplo, é de 20 quilômetros, o que impossibilita identificar nuvens de tempestade que podem ter de dois a três quilômetros de extensão. Além disso, eles fornecem previsões apenas a cada três horas, limitando a capacidade de detectar fenômenos meteorológicos extremos que surgem, desenvolvem-se e desaparecem em um menor período de tempo.

“O nível de detalhe espacial e temporal é hoje uma das maiores limitações para a melhoria da previsão do tempo no país que depende, fundamentalmente, da melhoria da resolução dos modelos meteorológicos”, disse Seluchi.

Para isso, os pesquisadores do Inpe pretendem com o novo supercomputador aumentar a resolução do modelo meteorológico regional utilizado nas previsões de tempo da instituição dos atuais 20 quilômetros para cinco quilômetros nos próximos anos. E paralelamente a essa mudança, também fazer com que possam representar de forma mais realista processos físicos que até então eram ignorados nos modelos anteriores.

De acordo com Seluchi, o supercomputador também possibilitará melhorar a geração do chamado diagnóstico ou “condição inicial” – o ponto de partida da elaboração dos modelos meteorológicos.

Qualquer erro nessa fase inicial da previsão, que se inicia com um diagnóstico preliminar da atmosfera a partir da coleta de observações de estações meteorológicas em terra, ar, oceano e espaço, pode provocar grandes falhas na previsão final.

“A geração dessa condição inicial será feita com uma metodologia muito mais cara e sofisticada do ponto de vista computacional, que incorporará uma série de novos dados”, disse.

Para diminuir a margem de erro nesse diagnóstico inicial, com o supercomputador o CPTEC, a exemplo dos principais centros meteorológicos no mundo, passará a gerar por meio de uma técnica matemática uma série de previsões climáticas paralelas.

Chamadas “previsões por conjunto”, segundo Seluchi, o grupo de previsões também permitirá aumentar a confiabilidade das previsões e indicar com maior assertividade a probabilidade de chuvas de grandes proporções.

“Ao rodar 20 previsões, das quais 18 apontam para um evento meteorológico extremo e as outras duas não, por exemplo, o meteorologista terá muito mais confiança para fazer suas previsões e decidir se é necessário enviar ou não um alerta para a Defesa Civil sobre um possível fenômeno extremo”, explicou.

Os primeiros novos modelos meteorológicos gerados pelo novo supercomputador, que foi adquirido com recursos da FAPESP e do Ministério da Ciência e Tecnologia (MCT), serão gerados para efeito de teste este mês. O sistema também será utilizado para pesquisar as novas gerações de modelos que serão utilizados para fazer previsões de mudanças climáticas no futuro.

Terra sacudida

O Nordeste brasileiro é terra de agitos, não só por causa do Carnaval e outras festividades. De acordo com pesquisadores do Rio Grande do Norte e de São Paulo, os terremotos que de vez em quando sacodem a região estão longe de ser novidade: já aconteciam muito antes de existir gente no planeta, e ocorrem até hoje. O geólogo Francisco Hilario Bezerra, da Universidade Federal do Rio Grande do Norte (UFRN), recorre à cultura popular para ressaltar a concepção errada que impera sobre os movimentos do solo brasileiro: “Vai, vai, vai, suba aqui na minha moto/ Vem, vem, vem, aqui não tem terremoto”, diz a música Insolação do coração, de Carlinhos Brown, interpretada por Claudia Leitte. Segundo o pesquisador, não é nada disso. No Brasil, sobretudo em sua região natal, tem muito terremoto.

“O Nordeste é o lugar do Brasil onde mais acontecem terremotos”, diz Bezerra, “não se sabe bem por quê”. Os resultados do grupo da UFRN deixam claro que terremotos têm sido comuns na região nos últimos 400 mil anos. Além de explicar o relevo nordestino, esse conhecimento pode também ter utilidade prática direta, como orientar a engenharia civil. “Se determinamos que uma zona é caracterizada, há milhares de anos, por terremotos de magnitude 5, por exemplo, é preciso que as construções resistam a esses tremores”, explica o geólogo.

A caracterização tectônica da região faz parte de um projeto mais amplo coordenado pelo geólogo Reinhardt Fuck, da Universidade de Brasília, no âmbito do Instituto Nacional de Ciência e Tecnologia (INCT) de Estudos Tectônicos. Parte do trabalho foi feita por Francisco Cézar Nogueira durante o doutorado sob orientação de Bezerra. Ele estudou uma falha tectônica com comprimento de 35 quilômetros por onde corre o rio Jundiaí, que corta a cidade de Natal, e viu que, mais ou menos a cada 16 mil anos, os movimentos dessa ruptura no terreno causam tremores, segundo artigo publicado este ano no Journal of Geodynamics.

A principal fonte de informações para Nogueira foi a areia que preenche as rachaduras profundas do solo. Como matéria-prima para análises geológicas, a areia pode ser desafiante. As zonas arenosas em climas áridos são pouco propensas à preservação de fósseis e por isso são difíceis de datar pela técnica mais comum, de carbono-14. A dificuldade foi resolvida por uma associação com o laboratório de Sonia Tatumi, da Faculdade de Tecnologia de São Paulo (Fatec-SP), especialista em análises de luminescência opticamente estimulada. A técnica mede a posição dos elétrons dentro dos grãos de quartzo da areia para avaliar sua idade. A luz solar atrai esses elétrons para a camada mais externa, mas eles voltam para o interior do grão quando a camada de areia é enterrada. Com esse método é possível estimar há quanto tempo o grão está no subsolo, dentro de um máximo de 1 milhão de anos. Ao pressupor que a areia infiltrada na falha Jundiaí foi soterrada em consequência da rachadura, as datações permitiram estimar que ela se formou cerca de 100 mil anos atrás. E esteve ativa desde então, o que não se podia saber observando os registros históricos. Durante os 200 anos em que há histórico sobre a atividade sísmica ­no Nordeste, não foram registrados tre­mores fortes na falha Jundiaí, o que poderia levar a crer – incorretamente – que ela não está ativa.

Solo movediço – Estudar falhas não é a única forma de investigar a sismologia de uma região. Mesmo sem ter acesso direto à falha que causa tremores em determinada área, o grupo da UFRN usa também outras alterações no solo para inferir movimentos passados. Um desses fenômenos é a liquefação, que acontece quando uma mistura de água e areia presa no subsolo é submetida a grande pressão, como a gerada por um terremoto. Bezerra ajuda a compreender fazendo uma analogia com a pressão que se cria quando uma garrafa de champanhe é sacudida. “A rolha, que no caso do solo pode ser uma rocha, impede a mistura de se expandir e a pressão aumenta até que estoura”, explica. No caso do champanhe é festivo, desde que a rolha não atinja alguém; mas quando grãos de quartzo se agitam com um terremoto e são ejetados, junto com a água, depois que a rocha se rompe, o resultado é destruição e, hoje, prédios demolidos.

As marcas desse tremor depois se solidificam e ficam registradas: é o que Elissandra Moura-Lima tem estudado durante seu trabalho de doutorado. As testemunhas providenciais aí são seixos por cima da areia. Mais uma vez, Bezerra recorre a uma imagem para deixar clara a instabilidade dessa disposição: “Imagine uma gelatina, dessas que a gente come, com um ferro de passar em cima”. Basta um tremor para acabar com o equilíbrio e fazer o ferro afundar. E provavelmente fará isso de lado, descendo pela gelatina na posição que oferece menos resistência. É o que acontece com os seixos: quando são flagrados debaixo da superfície em posição vertical, os pesquisadores podem inferir o trajeto que percorreram. E, mais uma vez com ajuda da luminescência, estimar quando aconteceram esses movimentos.

Elissandra usou também uma espécie de tomografia dos sedimentos conhecida como GPR, sigla em inglês para radar que penetra o solo (ground penetrating radar). Isso lhe permitiu caracterizar, no vale do rio Açu, parte da bacia Potiguar, as estruturas em domo formadas quando os seixos penetram solo adentro e empurram a areia para cima. Mapear essas deformações do solo no contexto da rede de falhas que percorre a região permite estimar o momento e a magnitude de tremores que ocorreram há milhares de anos. Um tremor de magnitude 5 ou 6, por exemplo, causa alterações num raio de dois quilômetros. No vale do rio Açu, o grupo mostrou que terremotos já eram recorrentes há 400 mil anos. As falhas que correm por baixo desse vale são, por isso, fortes candidatas a responsáveis por boa parte da atividade sísmica do passado na bacia Potiguar.

Mais que paisagem – Uma vantagem de ser geólogo especializado nessa região é poder trabalhar num cenário mais atraente do que pedreiras ou zonas desérticas. As falésias que caracterizam boa parte da costa nordestina são, além de deslumbrantes, uma fonte rica de informações. Naquelas paredes com até 30 metros de altura que se erguem junto ao mar coloridas com tons de vermelho, amarelo, roxo e branco está exposto um histórico sísmico e geológico que remonta a dezenas de milhares de anos. Basta a um especialista olhar para essas falésias para perceber as linhas horizontais que delimitam sedimentos com idades diferentes e reconhecer características que revelam a influência de atividades sísmicas em sua formação.

É nessa paisagem que se dá parte do trabalho de Dilce Rossetti, do Instituto Nacional de Pesquisas Espaciais (Inpe), que também analisa faces rochosas onde for possível, como as cortadas pela abertura de estradas. “A costa nordestina é ideal para esse tipo de estudo”, explica a pesquisadora, “pela abundância de falésias que se estendem por muitos quilômetros”. Isso lhe permite comparar as deformações no terreno causadas pela liquefação em contextos diversos, como perto de uma falha e longe dela, além de ter acesso, num único ponto de uma praia paradisíaca, a uma história com dezenas de milhares de anos. Em artigo que será publicado em janeiro de 2011, junto com o de Elissandra, numa edição especial sobre paleoterremotos da Sedimentary Geology, Dilce usa essas deformações para mostrar como a ponta da Paraíba, último ponto do continente americano a se desligar da África, não é passiva como se pensava. A atividade sísmica ali é disseminada.

Para datar esses eventos ela tem usado carbono-14, quando há matéria orgânica, e luminescência, cujos resultados estão em fase final de preparação para publicação. Ela viu que por cima da formação geológica conhecida como Barreiras, formada há cerca de 20 milhões de anos, há várias camadas com sinais de perturbação sísmica. Chegou a encontrar rochas com idade de 178 mil anos numa falésia paraibana, mas o mais comum é ter registros dos últimos 67 mil anos. “Nessa época já havia sismicidade em vários locais da Paraí­ba, e em outros estados do Nordeste também”, afirma. Segundo Dilce, esses movimentos de terra foram responsáveis por modelar parte do relevo da região, como as falésias e a localização dos leitos de alguns rios.

Não é possível extrapolar os resultados obtidos no Nordeste para outras regiões do Brasil. “Cada falha tem um comportamento específico”, explica Bezerra. Por isso as falhas paulistas de Taubaté e de Santos, por exemplo, podem ter uma periodicidade e um modo de ação distintos que ainda precisam ser estudados. Para ele, a grande importância desses trabalhos, em conjunto, é mostrar que olhar os fenômenos atuais da natureza não é suficiente para entender o que acontece hoje. “O conhecimento histórico e instrumental não basta, é preciso examinar as camadas do passado distante.”

Um dos maiores supercomputadores do mundo para previsão de tempo e de mudanças climáticas é inaugurado em Cachoeira Paulista. Equipamento permitirá fazer previsões de tempo mais confiáveis, com maior prazo de antecedência e de melhor qualidade (foto: Eduardo Cesar/Ag.FAPESP)

Agência FAPESP – O Instituto Nacional de Pesquisas Espaciais (Inpe) inaugurou terça-feira (28/12), no Centro de Previsão do Tempo e Estudos Climáticos (CPTEC), em Cachoeira Paulista (SP), o supercomputador Tupã.

Com o nome do deus do trovão na mitologia tupi-guarani, o sistema computacional é o terceiro maior do mundo em previsão operacional de tempo e clima sazonal e o oitavo em previsão de mudanças climáticas.

Não apenas isso. De acordo com a mais recente relação do Top 500 da Supercomputação, que lista os sistemas mais rápidos do mundo, divulgada em novembro, o Tupã ocupa a 29ª posição. Essa é a mais alta colocação já alcançada por uma máquina instalada no Brasil.

Ao custo de R$ 50 milhões, dos quais R$ 15 milhões foram financiados pela FAPESP e R$ 35 milhões pelo Ministério da Ciência e Tecnologia (MCT), por meio da Financiadora de Estudos e Projetos (Finep), o sistema foi fabricado pela Cray, em Wisconsin, nos Estados Unidos.

O Tupã é capaz de realizar 205 trilhões de operações de cálculos por segundo e processar em 1 minuto um conjunto de dados que um computador convencional demoraria mais de uma semana.

Com vida útil de seis anos, o equipamento permitirá ao Inpe gerar previsões de tempo mais confiáveis, com maior prazo de antecedência e de melhor qualidade, ampliando o nível de detalhamento para 5 quilômetros na América do Sul e 20 quilômetros para todo o globo.

A máquina também possibilitará melhorar as previsões ambientais e da qualidade do ar, gerando prognósticos de maior resolução – de 15 quilômetros – com até seis dias de antecedência, e prever com antecedência de pelo menos dois dias eventos climáticos extremos, como as chuvas intensas que abateram as cidades de Angra dos Reis (RJ) e São Luiz do Paraitinga (SP) no início de 2010.

“Com o novo computador, conseguiremos rodar modelos meteorológicos mais sofisticados, que possibilitarão melhorar o nível de detalhamento das previsões climáticas no país”, disse Marcelo Enrique Seluchi, chefe de supercomputação do Inpe e coodernador substituto do CPTEC, à Agência FAPESP.

Segundo o pesquisador, no início de janeiro de 2011 começarão a ser rodados no supercomputador, em nível de teste, os primeiros modelos meteorológicos para previsão de tempo e de mudanças climáticas. E até o fim de 2011 será possível ter os primeiros resultados sobre os impactos das mudanças climáticas no Brasil com dados que não são levados em conta nos modelos internacionais.

Modelo climático brasileiro

De acordo com Gilberto Câmara, diretor do Inpe, o supercomputador foi o primeiro equipamento comprado pela instituição de pesquisa que dispensou a necessidade de financiamento estrangeiro.

“Todos os outros três supercomputadores do Inpe contaram com financiamento estrangeiro, que acaba custando mais caro para o Brasil. O financiamento da FAPESP e do MCT nos permitiu realizar esse investimento sem termos que contar com recursos estrangeiros”, afirmou.

O supercomputador será utilizado, além do Inpe, por outros grupos de pesquisa, instituições e universidades integrantes do Programa FAPESP de Pesquisa em Mudanças Climáticas Globais, da Rede Brasileira de Pesquisa sobre Mudanças Climática (Rede Clima) e do Instituto Nacional de Ciência e Tecnologia (INCT) para Mudanças Climáticas.

Em seu discurso na inauguração, Carlos Henrique de Brito Cruz, diretor científico da FAPESP, destacou a importância do supercomputador para o avanço das pesquisas realizadas no âmbito do Programa FAPESP de Pesquisa em Mudanças Climáticas Globais, que foi concebido para durar pelo menos dez anos, e para a criação do Modelo Brasileiro do Sistema Climático Global (MBSCG).

O modelo incorporará os elementos do sistema terrestre (atmosfera, oceanos, criosfera, vegetação e ciclos biogeoquímicos, entre outros), suas interações e de que modo está sendo perturbado por ações antropogênicas, como, por exemplo, emissões de gases de efeito estudo, mudanças na vegetação e urbanização.

A construção do novo modelo envolve um grande número de pesquisadores do Brasil e do exterior, provenientes de diversas instituições. E se constitui em um projeto interdisciplinar de desenvolvimento de modelagem climática sem precedentes em países em desenvolvimento.

“Não tínhamos, no Brasil, a capacidade de criar um modelo climático global do ponto de vista brasileiro. Hoje, a FAPESP está financiando um grande programa de pesquisa para o desenvolvimento de um modelo climático brasileiro”, disse Brito Cruz.

Na avaliação dele, o supercomputador representará um avanço na pesquisa brasileira em previsão de tempo e mudanças climáticas globais, que são duas questões estratégicas para o país.

Impossibilitado de participar do evento, o ministro da Ciência e Tecnologia, Sergio Rezende, gravou um vídeo, exibido na solenidade de inauguração do supercomputador, em que declarou o orgulho da instalação no Brasil do maior supercomputador do hemisfério Sul.

“Com esse supercomputador, o Brasil dá mais um passo para cumprir as metas de monitoramento do clima assumidas internacionalmente e entra no seleto grupo de países capazes de gerar cenários climáticos futuros”, disse.

>Four in 10 Americans Believe in Strict Creationism (Gallup)

>
December 17, 2010

Belief in evolutionary origins of humans slowly rising, however
by Frank Newport

PRINCETON, NJ — Four in 10 Americans, slightly fewer today than in years past, believe God created humans in their present form about 10,000 years ago. Thirty-eight percent believe God guided a process by which humans developed over millions of years from less advanced life forms, while 16%, up slightly from years past, believe humans developed over millions of years, without God’s involvement.

A small minority of Americans hold the “secular evolution” view that humans evolved with no influence from God — but the number has risen from 9% in 1982 to 16% today. At the same time, the 40% of Americans who hold the “creationist” view that God created humans as is 10,000 years ago is the lowest in Gallup’s history of asking this question, and down from a high point of 47% in 1993 and 1999. There has been little change over the years in the percentage holding the “theistic evolution” view that humans evolved under God’s guidance.

Americans’ views on human origins vary significantly by level of education and religiosity. Those who are less educated are more likely to hold a creationist view. Those with college degrees and postgraduate education are more likely to hold one of the two viewpoints involving evolution.

December 2010 Views of Human Origins (Humans Evolved, With God Guiding; Humans Evolved Without God's Involvment; God Created Humans in Present Form) -- by Education

Americans who attend church frequently are most likely to accept explanations for the origin of humans that involve God, not a surprising finding. Still, the creationist viewpoint, held by 60% of weekly churchgoers, is not universal even among the most highly religious group. Also, about a fourth of those who seldom or never attend church choose the creationist view

December 2010 Views of Human Origins (Humans Evolved, With God Guiding; Humans Evolved Without God's Involvment; God Created Humans in Present Form) -- by Frequency of Church Attendance

The significantly higher percentage of Republicans who choose a creationist view of human origins reflects in part the strong relationship between religion and politics in contemporary America. Republicans are significantly more likely to attend church weekly than are others, and, as noted, Americans who attend church weekly are most likely to select the creationist alternative for the origin of humans.

December 2010 Views of Human Origins (Humans Evolved, With God Guiding; Humans Evolved Without God's Involvment; God Created Humans in Present Form) -- by Party

Implications

Most Americans believe in God, and about 85% have a religious identity. It is not surprising as a result to find that about 8 in 10 Americans hold a view of human origins that involves actions by God — that he either created humans as depicted in the book of Genesis, or guided a process of evolution. What no doubt continues to surprise many scientists is that 4 out of 10 Americans believe in the first of these explanations.

These views have been generally stable over the last 28 years. Acceptance of the creationist viewpoint has decreased slightly over time, with a concomitant rise in acceptance of a secular evolution perspective. But these shifts have not been large, and the basic structure of beliefs about human beings’ origins is generally the same as it was in the early 1980s.

Americans’ attitudes about almost anything can and often do have political consequences. Views on the origins of humans are no exception. Debates and clashes over which explanations for human origins should be included in school textbooks have persisted for decades. With 40% of Americans continuing to hold to an anti-evolutionary belief about the origin of humans, it is highly likely that these types of debates will continue.

Survey Methods

Results for this Gallup poll are based on telephone interviews conducted Dec. 10-12, 2010, with a random sample of 1,019 adults, aged 18 and older, living in the continental U.S., selected using random-digit-dial sampling.

For results based on the total sample of national adults, one can say with 95% confidence that the maximum margin of sampling error is ±4 percentage points.

Interviews are conducted with respondents on landline telephones (for respondents with a landline telephone) and cellular phones (for respondents who are cell phone-only). Each sample includes a minimum quota of 150 cell phone-only respondents and 850 landline respondents, with additional minimum quotas among landline respondents for gender within region. Landline respondents are chosen at random within each household on the basis of which member had the most recent birthday.

Samples are weighted by gender, age, race, education, region, and phone lines. Demographic weighting targets are based on the March 2009 Current Population Survey figures for the aged 18 and older non-institutionalized population living in continental U.S. telephone households. All reported margins of sampling error include the computed design effects for weighting and sample design.

In addition to sampling error, question wording and practical difficulties in conducting surveys can introduce error or bias into the findings of public opinion polls.

Clima mata 21 mil em 2010 e ministra pede ajuda aos deuses na Cúpula de Cancun

Desastres climáticos registrados nos primeiros nove meses deste ano foram responsáveis por 21 mil mortes – o dobro do número confirmado no mesmo período do ano passado, segundo dados divulgados pela organização humanitária Oxfam.

O relatório cita as enchentes no Paquistão, as ondas de calor na Rússia e a elevação do nível do mar em Tuvalu, como exemplos das letais conseqüências das mudanças climáticas. E o futuro não é nada promissor: um outro estudo revela que em 50 anos, o mundo estará 4 graus Celsius mais quente, o que vai impor severas alterações climáticas.

Os dados foram divulgados na segunda-feira (29/11), dia de abertura da 16ª Convenção da ONU sobre Mudanças Climáticas (COP-16), em Cancún, no México. A cerimônia de abertura foi marcada por discursos para forçar um novo engajamento dos países em torno de um acordo para conter o aquecimento global.

A secretária-executiva da convenção, Christiana Figueres, chegou a apelar para os deuses, pedindo que a deusa maia da Lua, Ixchel, inspire os negociadores dos 194 países que participam do evento.

– Bem-vindos à terra da deusa maia da Lua, Ixchel, que também era deusa da razão, da criatividade e da liderança – afirmou ela. – Que ela inspire a todos vocês, porque hoje (segunda-feira) vocês estão reunidos aqui em Cancún para chegar a uma sólida resposta às mudanças climáticas, usando razão e criatividade. Estou convencida de que daqui a 20 anos vamos admirar a tapeçaria que nos tecemos juntos e lembrar com carinho de Cancún e da inspiração da deusa Ixchel.

“Bem-vindos à terra da deusa maia da Lua, Ixchel, que também era deusa da razão, da criatividade e da liderança. Que ela inspire a todos vocês, porque hoje vocês estão reunidos aqui em Cancún para chegar a uma sólida resposta às mudanças climáticas, usando razão e criatividade. Estou convencida de que daqui a 20 anos vamos admirar a tapeçaria que nos tecemos juntos e lembrar com carinho de Cancún e da inspiração da deusa Ixchel”

Segundo o documento da Oxfam, as enchentes no Paquistão inundaram um quinto do país, matando 2 mil pessoas e afetando 20 milhões em razão da destruição de casas, escolas, rodovias e cultivos e da disseminação de doenças. Um prejuízo estimado em US$ 9,7 bilhões.

Na Rússia, as temperaturas excederam a média de julho e agosto em 7,8 graus Celsius, o que fez a taxa diária de óbitos em Moscou dobrar, alcançando 700. Pelo menos 26 mil focos de incêndio destruíram um quarto das plantações de trigo, gerando um problema nas exportações.

Os moradores da nação insular Tuvalu, no Pacífico, onde a elevação do nível do mar é de 5 a 6 milímetros ao ano, enfrentam cada vez mais dificuldades para manter cultivos, uma vez que a água salobra está invadindo as plantações.

E o futuro será muito pior, como apontam dados climáticos. As crianças de hoje vão alcançar a velhice num mundo 4 graus Celsius mais quente, onde certezas climáticas que valeram para os últimos dez mil anos não serão mais referência. Secas, enchentes e migrações em massa serão parte da vida diária já a partir de 2060.

Será provavelmente a década a partir da qual, pela primeira vez desde o fim da Idade do Gelo, a Humanidade terá que lidar com um clima global bastante instável e imprevisível. As previsões fazem parte de uma série de estudos científicos publicados na segunda-feira (29/11) sobre o mundo 4 graus Celsius mais quente.

As negociações em Cancún ainda giram em torno de tentar manter a elevação das temperaturas em, no máximo, 2 graus Celsius. Segundo muitos cientistas, no entanto, as atuais tendências revelam que um aumento de 3 a 4 graus é “muito mais provável”.

A maior preocupação é que uma elevação de 4 graus Celsius na temperatura média global – uma diferença tão grande quanto a que separa o clima atual daquele registrado na última Idade do Gelo – geraria transformações dramáticas no mundo, levando a secas, colapso da agricultura em regiões semiáridas e a um catastrófico aumento do nível do mar em áreas costeiras.

O anfitrião da COP-16, o presidente mexicano Felipe Calderon, fez um apelo para que os negociadores cheguem a um acordo para mudar os rumos da crise climática.

Ele disse que as futuras gerações irão cobrar, caso eles falhem em alcançar um resultado.

– Será uma tragédia que nossa incapacidade nos leve a falhar – afirmou, citando que em seu país só este ano 60 pessoas morreram por desastres causados pelo aquecimento da Terra.

COP-16 começa no próximo dia 29, em Cancún, México

Um ano após a grande frustração que foi a Convenção das Nações Unidas sobre Mudanças Climáticas em Copenhague (COP-15), a nova edição da convenção, em Cancún (COP-16), começa no próximo dia 29 sem expectativas de grandes resultados

Prova disso é que são esperados apenas entre 20 e 30 chefes de estado no México, contra 118 que estiveram presentes em Copenhague. O presidente Lula, uma das grandes estrelas do último encontro, já confirmou sua ida, mas a delegação brasileira encolheu de 900 pessoas, no ano passado, para 250 este ano.

Não se espera o fechamento de um grande acordo vinculante com metas significativas de redução de emissão de CO2 para o segundo período de compromisso do Protocolo de Kyoto, que vence em 2012, e é uma obrigação dos países desenvolvidos que assinaram o documento. Tampouco deverá haver resultados importantes na área de financiamento, outro ponto-chave da negociação.

Este é mais um compromisso firmado pelos países desenvolvidos: prover recursos financeiros para que países em desenvolvimento possam prevenir os efeitos das mudanças climáticas (mitigação) e se adaptar àqueles que já podem ser sentidos nos países mais vulneráveis, como pequenas ilhas do pacífico e nações africanas.

– Você chega a Cancún sem aquela comoção com que se chegou em Copenhague e com as mesmas dificuldades. As expectativas agora são mais modestas – avalia o embaixador Luiz Figueiredo, negociador-chefe do Brasil na Convenção do Clima da ONU.

O Brasil tem ganhado um papel protagonista na convenção e vai levar para Cancún dois trunfos na bagagem: a apresentação do último balanço sobre o desmatamento da Amazônia e a explicação dos planos setoriais que vêm sendo elaborados para que o país cumpra as metas voluntárias de redução de emissões.

Sobre a Amazônia, deve ser anunciado um novo recorde histórico, no qual “somente” cerca de 5 mil km2 teriam sido destruídos entre 2009 e 2010. Já sobre as emissões, o governo brasileiro vai mostrar como pretende reduzir de 36% a 39% de suas emissões, com relação ao que o país calculou que vai emitir em 2020. Na prática, significaria emitir 1,7 giga toneladas de CO2 daqui a dez anos, quando o esperado era a emissão de 2,7 giga toneladas de CO2.

– Lula terá um papel muito destacado em Cancún. Com a proposta ambiciosa que apresentou em Copenhague, ele foi o chefe de Estado que mais chamou a atenção – diz o secretário-executivo do Fórum Brasilieiro de Mudanças Climáticas, Luiz Pinguelli Rosa.

O principal plano brasileiro é reduzir a derrubada da Amazônia em 80% até 2020 e do Cerrado em 40%. As duas medidas, se alcançadas, evitarão a emissão de 668 milhões de toneladas de CO2. O desmatamento responde por 61% das emissões brasileiras.

A agricultura, dona de 22% das emissões, também sofrerá alterações. Uma das ações previstas é a recuperação de 15 milhões de hectares de pastagens degradadas, de um total de 60 milhões que o país possui, e a implementação de um programa de agricultura de baixo carbono. Com isso seriam cortadas pelo menos 183 milhões de toneladas de CO2.

No setor energético, que gera 15% de nossas emissões, o governo prepara um pacote para aumentar o uso de biocombustíveis, reduzindo entre 48 e 60 milhões de toneladas de CO2. E na siderurgia, setor ainda bastante dependente de carvão produzido com madeira de desmatamento, a ideia é justamente substituí-lo por carvão vegetal de florestas plantadas. A ação pode gerar o corte de entre 8 e 10 toneladas de CO2. As carvoarias emitem 31% do total registrado no setor energético.

Além desses cinco setores, o governo vai incluir outras sete áreas para as quais também serão criados planos setoriais. A principal delas é o transporte. Listado dentro da seção “energia”, o transporte rodoviário responde por 38% dessas emissões.

– O transporte será uma área decisiva para o Brasil no futuro, pois passará a contribuir cada vez mais para o nível de emissões, principalmente por conta da ineficiência do transporte de carga. O Brasil tem, há 15 anos, o pior desempenho do mundo em transporte de cargas – aponta Eduardo Viola, professor de Relações Internacionais da UnB.

Ele critica também o transporte público brasileiro que receberia incentivos para o aumento no número de carros nas ruas, quando deveria ocorrer justamente o contrário. Ele sugere que o país monte um programa para penalizar o uso de carros (como taxas para quem roda nos centros das grandes cidades), o que geraria pressão para estimular investimentos em transporte público de alta capacidade para passageiros, como trens e metrôs. No caso do transporte de suprimentos, a saída, segundo o professor, é ampliar a rede ferroviária e hidroviária.

O pacote que o Brasil apresentará vai esbarrar com a dura realidade que vigora nas negociações climáticas. Com relação às metas de redução dos países desenvolvidos, até agora apenas 15 nações manifestaram suas intenções, a maioria condicionando números mais ambiciosos a um acordo global, o que ainda não aconteceu.

Por enquanto, o que se tem é uma redução que varia de 16% a 18% com relação às emissões de 1990. Isso seria insuficiente para evitar um aumento da temperatura da Terra de mais de 2 graus Celsius, conforme concordaram os 140 países que assinaram o Acordo de Copenhague – documento fechado na COP-15, mas que não tem validade jurídica. Ou seja: é um texto de intenções.

A questão do financiamento também está em aberto. Na última reunião, os países concordaram com a criação de um Fundo de Início Rápido (Fast Track Fund), que proveria US$ 30 bilhões em três anos para que os países mais necessitados pudessem começar a agir contra o aquecimento global.

A fonte de recursos já foi identificada, mas esbarra em um problema: alguns dizem que o dinheiro de que se fala não é novo e configuraria um desvio de finalidade de recursos já comprometidos em outras áreas da cooperação internacional, como saúde e educação. O resultado é que, até agora, nenhum projeto foi contemplado com tal verba.

Um outro mecanismo acordado, mas que também não saiu do papel é o Fundo Verde Climático, para o qual seriam doados US$ 100 bilhões anuais até 2020. Esse dinheiro poderia ajudar países a criar mecanismos de eficiência energética, instalar aterros sanitários e manter florestas preservadas.

As regras são as mesmas: países ricos pagariam e países em desenvolvimento, como Brasil e África do Sul, implantariam localmente tais iniciativas. Como o aporte de dinheiro é alto, há divergências sobre de onde sairia. Dificilmente essa questão será solucionada em Cancún. Mas a ONG ambientalista WWF acredita que será possível avançar na estruturação do fundo, como o conselho que definirá prioridades a serem seguidas e os fiadores do sistema.

– Seria uma grande forma de reconstruir a confiança e demonstrar que os países industrializados estão tratando a mudança do clima com seriedade – pondera Mark Lutes, coordenador de políticas financeiras da Iniciativa Climática Global da WWF.

Para tentar solucionar o impasse sobre a fonte de recursos que abastecerá o Fundo Verde, o Grupo de Alto Nível em Financiamento de Mudanças Climáticas da ONU (AGF) elaborou um estudo apontando algumas alternativas, como a taxação de viagens internacionais no setor aéreo e de navegação, o que geraria potencialmente US$ 10 bilhões anuais. O setor, embora represente apenas 2% das emissões globais, é o que vem aumentando mais rapidamente sua fatia.

Apesar do clima de pessimismo que cerca o início da COP-16, em algumas áreas há chances reais de se chegar a algum acordo positivo. O anfitrião da convenção, o presidente mexicano Felipe Calderón, deposita todas as suas fichas na criação do REDD (Redução de Emissões por Desmatamento e Degradação). Iniciativas nessa área são consideradas ações de mitigação e, portanto, podem ser contempladas com recursos do Fundo Verde e do Fast Track Fund.

– Provavelmente o avanço mais importante que se fará em Cancún será em REDD, sobre as emissões florestais reguladas. Por isso me sinto otimista sobre este lado da equação – disse Calderón durante sua participação na última reunião do G-20, na Coreia do Sul.

O mecanismo, que inicialmente previa somente ações de combate ao desmatamento, ganhou um sobrenome: plus. Isso significou a inclusão de ações de conservação (como a criação de parques e reservas naturais) e técnicas de manejo florestal (nas quais madeira pode ser explorada de forma seletiva e ao longo de várias décadas para permitir a reposição das árvores cortadas). Segundo a pesquisadora do Instituto Alberto Luiz Coimbra de Pós-graduação e Pesquisa de Engenharia (Coppe) da UFRJ, Thelma Krug, as duas primeiras fases do REDD deverão ser implementadas ainda em Cancún.

A primeira fase diz respeito à preparação dos países ricos em floresta – como Brasil, Indonésia, Congo e Papua Nova Guiné – para monitorar o desmatamento. Nesta etapa, serão elaborados planos nacionais para reduzir o desflorestamento e montada uma rede para acompanhar os resultados. A capacitação de pessoal para trabalhar nessas atividades também é fundamental

A segunda fase prevê a implementação de projetos pilotos e o pagamento de serviços florestais. Em ambos os casos o Brasil dificilmente receberia recursos estrangeiros. Isso porque o país já possui um Plano Nacional para a Prevenção e Controle do Desmatamento da Amazônia e monitora por satélite a destruição do bioma há duas décadas.

– Acho que o Brasil não vai ver a cor desse dinheiro. Vai ser difícil convencer doadores a colocar recursos num país que já está conseguindo reduzir significativamente o desmatamento sozinho – pondera Thelma, uma das negociadoras brasileiras na convenção.

Por outro lado, os brasileiros têm muito a contribuir com os países mais atrasados. O governo assinou um acordo com a Organização das Nações Unidas para Agricultura e Alimentação (FAO) para transmitir tecnologia. Doadores pagarão para que técnicos de outros países venham aprender com os profissionais do Instituto Nacional de Pesquisas Espaciais (Inpe) as ferramentas de monitoramento em tempo real. A primeira turma, de africanos, virá no início do próximo ano.

Além disso, há chances de ser criado um comitê para coordenar as ações de adaptação, aquelas voltadas para minimizar as consequências da mudança do clima. Um Fundo de Adaptação já está em vigor, com recursos do Mecanismo de Desenvolvimento Limpo (MDL) – pelo qual os países desenvolvidos podem cumprir suas metas de redução de emissões bancando, em nações pobres, projetos que resultem em menos emissões.

Dois temas, entretanto, deverão aquecer os debates da COP-16: o primeiro é o fortalecimento do Protocolo de Kyoto, documento assinado em 1997, e que prevê a fixação, por parte dos países ricos, de cortes mensuráveis de emissões. Caso não sejam definidas metas para um segundo período do protocolo, a partir de 2013, ele pode se tornar ineficaz. Isso vai ser um problema porque a União Europeia, por exemplo, fez leis com base no protocolo.

Assim como em Copenhague, o X da questão continua sendo os Estados Unidos, que são os maiores poluidores do planeta, mas não assinaram Kyoto. Uma lei estipulando o corte de 17% das emissões americanas até 2020 com relação às de 2005 está empacada no Congresso com poucas chances de ser aprovada. A Europa também começou a recuar quanto à adoção de metas significativas de corte de emissões. Segundo negociadores brasileiros, os europeus vêm fazendo o jogo dos americanos para esticar até 2012 o impasse sobre metas.

O segundo problema são as ações de mitigação a serem adotadas pelos países em desenvolvimento, as chamadas Namas (Ações de Mitigação Nacionalmente Adequadas). Embora os emergentes não sejam obrigados a se comprometer com metas, foi estabelecido na convenção que adotarão medidas voluntárias.

O embaraço, nesse caso, se dá no acompanhamento dessas ações. A maioria dos países só aceita o monitoramento internacional das ações financiadas por dinheiro estrangeiro. A China é a principal opositora à possibilidade de outros países interferirem em medidas que estão sendo adotadas em seu território.

>Time to Take Action on Climate Communication (Science)

>
LETTERS

According to broad international agreement, a global warming increase beyond 2°C is unacceptable (1). Because of the physics of the climate system, we must ensure that global emissions of greenhouse gases peak and start to decline rapidly within a decade in order to have a reasonable chance of meeting the 2°C goal (2). Humankind has waffled and delayed for decades; further delay risks serious consequences for people and the ecosystems on which we rely.

Because the potential consequences of climate change are so high, the science community has an obligation to help people, organizations, and governments make informed decisions. Yet existing institutions are not well suited to this task. Therefore, we call for the science community to develop, implement, and sustain an independent initiative with a singular mandate: to actively and effectively share information about climate change risks and potential solutions with the public, particularly decision-makers in the public, private, and nonprofit sectors. Moreover, we call on philanthropic funding institutions to endorse and provide sustained support for the initiative.

The initiative must make concerted efforts to provide people, organizations, and governments with critical information, to address misperceptions, and to counter misinformation and deception. In doing so, it will have to overcome psychological and cultural barriers to learning and engagement (3–5).

The initiative should be judged against two critical outcomes: (i) improved understanding of risks and potential solutions by people, organizations, and governments, and (ii) more informed decision-making—and less avoidance of decision-making—about how to manage those risks. The initiative should be an embodiment of what Fischhoff calls “non-persuasive communication.” It should not advocate specific policy decisions; good decision-making involves weighing the best available information with the values of the decision-makers and those affected by the decisions.

The initiative should recruit a full range of climate scientists, decision scientists, and communication professionals into the effort (6, 7) to ensure both sound scientific information and effective communication. In addition, it should build bridges to other communities of experts—such as clergy, financial managers, business managers, and insurers—who help people, organizations, and governments assess and express their values. Scientists and nonscientists alike inevitably interpret climate science information in the context of other information and values; the initiative should mobilize experts who can facilitate appropriate and useful interpretations.

Despite the politically contentious nature of climate change policy, the initiative must be strictly nonpartisan. In the face of efforts to undermine public confidence in science, it must become a trusted broker of un biased information for people on all sides of the issue.

At this potentially critical moment for human civilization, it is imperative that people, organizations, and governments be given the resources they need to participate in constructive civic, commercial, and personal decision-making about climate change risks and solutions.

>Scientists Scramble to Bridge the Uncertainty Gap in Climate Science (N.Y. Times)

>
By AMANDA PETERKA of Greenwire
November 9, 2010

Skeptics of climate change — a good number of them about to take seats in Congress — often point to uncertainties or holes in the science as reasons for delaying or not taking action.

But uncertainty is the modus operandi of science, as Vaughan Turekian, chief international officer at the American Association for the Advancement of Science, describes it. Scientists report not only what is known but to what degree it is known.

“Science is never an open and closed case,” Turekian said.

Still, there is a fundamental difference between the way the public and policymakers see uncertainty and the way scientists do, which creates a gap that needs constant bridging, scientists say.

“When scientists talk about results they rarely focus on the things they know with great certainty. It seems counterintuitive to people who are not scientists, talking so much about what we don’t know,” said James McCarthy, a professor of oceanography at Harvard University.

“If you were to hear someone say, ‘I know with 100 percent certainty that the Earth’s climate will change or not,’ that would be a statement to walk away from because you would know right away that a scientist hasn’t made that statement.”

There are several coordinated efforts under way to bridge the gap. John Abraham, an associate engineering professor at Minnesota’s St. Thomas University, is creating a “climate rapid response team” of scientists who are open to addressing the politics of global warming. The American Geophysical Union, separately, is establishing a bank of climate scientists to serve as experts on global warming.

It is probably no coincidence that policy debates involving environmental issues have often been long and contentious. A number of environmental debates, including those over acid rain and the depletion of the ozone layer, have centered on scientific uncertainties.

Judith Curry, chairwoman of the School of Earth and Atmospheric Sciences at the Georgia Institute of Technology, blames climate scientists. She said the reason uncertainty has been especially played up in climate science is because “climate scientists were so vehement in their overconfidence, which just didn’t stand up given the complexity of the problem. … Trying to hide uncertainties just ends up compromising the scientists and confusing the policymaking process.”

Uncertainty, she said, should be used as information in the decisionmaking process. But for lawmakers, it is not easy to incorporate uncertainty into policy or to prove to constituents that an action is necessary. Moreover, the public is not well aware of how uncertainty is handled in science, according to Robert Costanza, director of the Institute for Sustainable Solutions at Portland State University In Oregon.

“That’s part of the problem, and that’s why the public opinion can be so easily manipulated because of that lack of basic understanding,” he said.

Government mechanisms

In the 1970s and 1980s, the United States had an Office of Technology Assessment, which analyzed complex scientific concepts, producing studies for Congress on subjects like the nation’s energy future and ecosystem management and giving advice on how to address issues. The office was defunded during the anti-big government wave that followed the release of the 1994 Republican document called “Contract with America” and the Republican takeover of the Senate during the first term of the Clinton administration.

Many other countries in Europe still have similar mechanisms, though, to assess the quality of scientific information. It is something the United States should consider again, said Thomas Dietz, vice chairman of the science panel in America’s Climate Choices, a study done by the National Academy of Sciences.

“We need to have a mechanism to take scientific understanding and make it available both to policymakers and to the public,” said Dietz, assistant vice president for environmental research at Michigan State University. “A lot of issues we don’t seem to have much space for a public discussion that doesn’t become heated and a matter of talking points and pundits.”

Scientists are waiting for integrity standards to come out of the Office of Science and Technology Policy, required by President Obama in a March 2009 executive order and a year-and-a-half overdue. Public Employees for Environmental Responsibility recently filed a lawsuit to obtain documents relating to the overdue standards. Without them, it has been difficult for government agencies to agree on policies for transparency, collaboration and public participation in data gathering and decisionmaking based on that data.

With the lack of government mechanisms, boosting science education in the United States might help the public understand the state of science and how to make decisions in the face of uncertainty, Dietz said. The most recent World Economic Forum report ranked the United States 48th in math and science education.

Strengthening science education, agreed Turekian, would strength critical thinking. And that, he said, is necessary to understand the complexity around climate change because the better you understand how scientific information is gathered, the better you understand the information itself.

“When you think about critical thinking, you don’t take as given either facts or counterfacts that are just imposed on you,” he said. “Rather, you take the time to sort of critically assess which uncertainties are more important and which uncertainties have nothing to do with the broader trends.”

The broader trends, he said, are understood: If atmospheric carbon dioxide is increased, there will be certain increases in temperature. The uncertainties that need more understanding are the feedback effects from increasing temperature, such as what warming would do to the makeup of clouds, and if clouds would lead to even more warming if they change.

That level of detail does not need to be known to put in place measures akin to insurance policies to guard against the range of effects, scientists tend to agree, though they also tend to stay out of the policy debate.

Costanza has tried to combine a precautionary principle with a polluter-pays principle in incorporating uncertainty into policy. The concept can also apply to environmental disasters like oil spills.

In his idea, companies that pollute or emit carbon dioxide must take out bonds that cover worst-case scenarios that would be held until uncertainty is removed. This would create an incentive for emitters to reduce uncertainty by funding independent research or adopting cleaner practices.

“If they don’t see it in financial terms, they’re going to try to avoid it or manage or manipulate the uncertainty rather than reducing it,” he said. “All it takes is a little muddying of the water so there’s not a clear answer to delay action for years and years. It takes a lot less money and effort to muddy the water than it does to clear the water.”

>Repensar a esquizofrenia (Fapesp)

>
11/11/2010

Agência FAPESP – Esquizofrenia é o assunto em destaque na capa da edição desta quinta-feira (11/11) da Nature, que avalia em editorial e em três artigos os avanços obtidos nos últimos cem anos na compreensão desse transtorno psíquico severo.
No editorial, a revista destaca que a pesquisa científica tem revelado as “complexidades assombrosas” da esquizofrenia, mas também tem mostrado novas rotas para o diagnóstico e o tratamento.

“Nos últimos anos, tem se avaliado que essa coleção de sintomas – que tipicamente se manifesta no início da vida adulta – representa um estágio posterior da enfermidade e que a própria enfermidade pode vir a ser uma coleção de síndromes, mais do que uma condição única”, destaca o editorial.

No primeiro artigo, Thomas Insel, do National Institute of Mental Health, nos Estados Unidos, faz uma revisão do conhecimento acumulado sobre o tema. Segundo ele, o futuro do assunto reside em “repensar” a esquizofrenia como um distúrbio do desenvolvimento neurológico.

“Esse novo foco poderá levar a novas oportunidades para a compreensão de mecanismos e para o desenvolvimento de tratamentos para o transtorno. Tratamentos têm sido experimentados há décadas, mas com pouca evolução e resultados na maioria das vezes insatisfatórios”, disse.

A esquizofrenia é uma desordem mental debilitante que afeta cerca de 1% da população mundial. No segundo artigo, Andreas Meyer-Lindenberg, da Universidade de Heidelberg, na Alemanha, discute como as novas tecnologias de obtenção de imagens estão deixando os aspectos apenas funcionais e estruturais para focar também nos mecanismos dos riscos da enfermidade.

Para o cientista, essas novas estratégias, como o uso de imagens em genética, possibilitam uma visão muito importante do sistema neural mediado pelo risco hereditário e ligado a variantes comuns associadas à esquizofrenia.

O artigo sugere que a caracterização dos mecanismos do transtorno por meio do desenvolvimento de tais técnicas poderá somar forças com os atuais projetos de pesquisa que visam à busca de tratamentos.

No terceiro artigo, Jim van Os, da Universidade Maastricht, na Holanda, e colegas fazem uma revisão do conhecimento atual a respeito das influências ambientais na esquizofrenia e os desafios que essas relações abrem para a pesquisa na área.

Os autores argumentam que mais pesquisas são necessárias para tentar descobrir a interação entre genética e ambiente que determina como a expressão da vulnerabilidade na população geral pode dar origem a mais psicopatologias severas.

>New documentary recounts bizarre climate changes seen by Inuit elders (Globe and Mail)

Movies
By GUY DIXON
Globe and Mail – Tuesday, Oct. 19, 2010

Imagine how this feels: The land and weather are turning erratic and dangerous. Warmer, unpredictable winds are coming from strange directions. Severe floods threaten to wash away towns. And native animals, the food supply, aren’t behaving as they used to, their bodies less capable in the changing climate.

Even stranger is the fact that the sun now appears to set many kilometres off its usual point on the horizon, and the stars are no longer where they should be. Is the Earth shifting on its axis, causing the very look of the sun and stars to change?

These are the drastic conditions Northern Canadians, whose lives depend from childhood on their knowledge of the most minute details of the Arctic land and skies, say they see all around them. These observations by Inuit elders are detailed in a groundbreaking new documentary, Inuit Knowledge and Climate Change, by acclaimed Nunavut filmmaker Zacharias Kunuk (The Fast Runner, The Journals of Knud Rasmussen) and environmental scientist Ian Mauro.

The documentary – screening at Toronto’s imagineNATIVE film and media arts festival this weekend and streaming live at isuma.tv – is the first to ask Inuit elders to describe the severe environmental changes in the Arctic they are seeing and to do so in their own language. The tone of the film is intimate. The elders aren’t trying to cross a language barrier, or even speak to the Southern scientific community. They’re simply imparting their expert knowledge and wisdom – and the result will undoubtedly cause controversy.

“Over the years, nobody has ever listened to these people. Every time [the discussion is] about global warming, about the Arctic warming, it’s scientists that go up there and do their work. And policy makers depend on these findings. Nobody ever really understands the people up there,” Kunuk says.

It quickly becomes clear that the film, which blends scenes of Inuit life with elders sharing their insights, is an invaluable document. The elders describe in precise detail how seal, for instance, a staple in their diet, are behaving troublingly due to the thinning ice, how warmer winds are changing the snow and ice banks, making overland navigation difficult, and how major floods are hitting communities.

Yet the elders talk about all this without anger, only a tinge of sadness. Kunuk says this is an Inuit characteristic, based on the belief that the world is forever changing, whether at the hand of man or through natural cycles. “We know for a fact that way up in the high Arctic, there are mummified tree trunks [showing that the Earth’s climate was once totally different]. Also, when Inuit hunters talk about animals, they always talk about cycles, everything goes in cycles. We just have to adapt to it.”

However, the faintest trace of anger does arise when the elders talk about polar bears. Contrary to what conservationists and scientists say, the elders interviewed in the film believe the polar-bear population is increasing. They say more bears finding their way into communities, and the animals are being traumatized by scientists, who are putting radio collars around the bears’ necks and doing other research that disturbs their natural life, usually spent in almost total isolation and silence.

Most startling for the filmmakers, though, was the Inuits’ belief that along with pollution and environmental changes, caused mainly by Southerners, the Earth has actually changed its tilt. The filmmakers kept hearing this theory in different communities. Perplexed, they contacted the U.S. National Aeronautics and Space Administration for answers, but experts said this was impossible.

When the filmmakers presented some of their findings at the Copenhagen conference on climate change last year, the media picked up on these views of the Inuit subjects, film co-director Ian Mauro says, and alarm bells started to ring in the scientific community. “We had a litany of scientists come back to us, responding after seeing this news, saying, ‘This was great to be speaking to indigenous people about their views, but if you continue to perpetuate this fallacy that the Earth had tilted on its axis, [the Inuit] …. would lose all credibility.’ And so there was really this backlash by the scientific community.”

Still, the Inuit insist they see changes in the sun’s course and the position of the stars in the night sky. “These elders, when they were growing up, they were told to go out every morning, before having anything to eat. They were told to go out at the age of 5 every morning to observe the weather,” Kunuk says. “So when they started talking about the sun and the sunset, I was puzzled too. Everywhere I went, each community, I was getting the same answer: The sun does not settle where it used to. I mean, it [causes] alarm.”

The scientific explanation is that the warming Arctic air is causing temperature inversions, which in turn cause the light of the sunset to refract so that the sun appears to be setting a few kilometres off-kilter. “There is so much garbage in the air, it’s refraction that’s causing our elders to think our world has tilted,” Kunuk says.

But the filmmakers don’t include that scientific explanation in the film, nor any other comments from the scientific community. Instead, the film deals strictly with the elders’ observations and their belief that they have no control over climate change and they simply have to adapt.

“We have to. We have no choice,” Kunuk says, repeating the elders’ quiet words.

Inuit Knowledge and Climate Change plays Toronto’s Al Green Theatre, 750 Spadina Ave., Saturday at 7 p.m., as part of the imagineNATIVE film and media arts festival. The film will be simultaneously streamed on http://www.isuma.tv.

>’Science as the Enemy’: The Traveling Salesmen of Climate Skepticism (Spiegel)

A handful of US scientists have made names for themselves by casting doubt on global warming research. In the past, the same people have also downplayed the dangers of passive smoking, acid rain and the ozone hole. In all cases, the tactics are the same: Spread doubt and claim it’s too soon to take action.

With his sonorous voice, Fred Singer, 86, sounded like a grandfather explaining the obvious to a dim-witted child. “Nature, not human activity, rules the climate,” the American physicist told a discussion attended by members of the German parliament for the business-friendly Free Democratic Party (FDP) three weeks ago.

Marie-Luise Dött, the environmental policy spokeswoman for the parliamentary group of Angela Merkel’s center-right Christian Democratic Union (CDU), also attended Singer’s presentation. She said afterwards that it was “extremely illuminating.” She later backpedaled, saying that her comments had been quoted out of context, and that of course she supports an ambitious climate protection policy — just like Chancellor Merkel.

Merkel, as it happens, was precisely the person Singer was trying to reach. “Our problem is not the climate. Our problem is politicians, who want to save the climate. They are the real problem,” he says. “My hope is that Merkel, who is not stupid, will see the light,” says Singer, who has since left for Paris. Noting that he liked the results of his talks, he adds: “I think I achieved something.”

Salesman of Skepticism

Singer is a traveling salesman of sorts for those who question climate change. On this year’s summer tour, he gave speeches to politicians in Rome, Paris and the Israeli port city of Haifa. Paul Friedhoff, the economic policy spokesman of the FDP’s parliamentary group, had invited him to Berlin. Singer and the FDP get along famously. The American scientist had already presented his contrary theories on the climate to FDP politicians at the Institute for Free Enterprise, a Berlin-based free-market think tank, last December.

Singer is one of the most influential deniers of climate change worldwide. In his world, respected climatologists are vilified as liars, people who are masquerading as environmentalists while, in reality, having only one goal in mind: to introduce socialism. Singer wants to save the world from this horror. For some, the fact that he made a name for himself as a brilliant atmospheric physicist after World War II lends weight to his words.

Born in Vienna, Singer fled to the United States in 1940 and soon became part of an elite group fighting the Cold War on the science front. After the collapse of the Soviet Union, Singer continued his struggle — mostly against environmentalists, and always against any form of regulation.

Whether it was the hole in the ozone layer, acid rain or climate change, Singer always had something critical to say, and he always knew better than the experts in their respective fields. But in doing so he strayed far away from the disciplines in which he himself was trained. For example, his testimony aided the tobacco lobby in its battle with health policy experts.

‘Science as the Enemy’

The Arlington, Virginia-based Marshall Institute took an approach very similar to Singer’s. Founded in 1984, its initial mission was to champion then US President Ronald Reagan’s Strategic Defense Initiative (SDI), better known as “Star Wars.” After the fall of the Iron Curtain, the founders abruptly transformed their institute into a stronghold for deniers of environmental problems.

“The skeptics thought, if you give up economic freedom, it will lead to losing political freedom. That was the underlying ideological current,” says Naomi Oreskes, a historian of science at the University of California, San Diego, who has studied Singer’s methods. As scientists uncovered more and more environmental problems, the skeptics “began to see science as the enemy.”

Oreskes is referring to only a handful of scientists and lobbyists, and yet they have managed to convince many ordinary people — and even some US presidents — that science is deeply divided over the causes of climate change. Former President George H.W. Bush even referred to the physicists at the Marshall Institute as “my scientists.”

Whatever the issue, Singer and his cohorts have always used the same basic argument: that the scientific community is still in disagreement and that scientists don’t have enough information. For instance, they say that genetics could be responsible for the cancers of people exposed to secondhand smoke, volcanoes for the hole in the ozone layer and the sun for climate change.

Cruel Nature

It almost seems as if Singer were trying to disguise himself as one of the people he is fighting. With his corduroy trousers, long white hair and a fish fossil hanging from a leather band around his neck, he comes across as an amiable old environmentalist. But the image he paints of nature is not at all friendly. “Nature is much to be feared, very cruel and very dangerous,” he says.

At conferences, Singer likes to introduce himself as a representative of the Nongovernmental International Panel on Climate Change (NIPCC). As impressive as this title sounds, the NIPCC is nothing but a collection of like-minded scientists Singer has gathered around himself. A German meteorologist in the group, Gerd Weber, has worked for the German Coal Association on and off for the last 25 years.

According to a US study, 97 percent of all climatologists worldwide assume that greenhouse gases produced by humans are warming the Earth. Nevertheless, one third of Germans and 40 percent of Americans doubt that the Earth is getting warmer. And many people are convinced that climatologists are divided into two opposing camps on the issue — which is untrue.

So how is it that people like Singer have been so effective in shaping public opinion?

Part 2: Experience Gained Defending Big Tobacco

Many scientists do not sufficiently explain the results of their research. Some climatologists have also been arrogant or have refused to turn over their data to critics. Some overlook inconsistencies or conjure up exaggerated horror scenarios that are not always backed by science. For example, sloppy work was responsible for a prediction in an Intergovernmental Panel on Climate Change (IPCC) report that all Himalayan glaciers would have melted by 2035. It was a grotesque mistake that plunged the IPCC into a credibility crisis.

Singer and his fellow combatants take advantage of such mistakes and utilize their experiences defending the tobacco industry. For decades, Big Tobacco managed to cast doubt on the idea that smoking kills. An internal document produced by tobacco maker Brown & Williamson states: “Doubt is our product since it is the best means of competing with the ‘body of fact’ that exists in the minds of the general public.”

In 1993, tobacco executives handed around a document titled “Bad Science — A Resource Book.” In the manual, PR professionals explain how to discredit inconvenient scientific results by labeling them “junk.” For example, the manual suggested pointing out that “too often science is manipulated to fulfill a political agenda.” According to the document: “Proposals that seek to improve indoor air quality by singling out tobacco smoke only enable bad science to become a poor excuse for enacting new laws and jeopardizing individual liberties.”

‘Junk Science’

In 1993, the US Environmental Protection Agency (EPA) published what was then the most comprehensive study on the effects of tobacco smoke on health, which stated that exposure to secondhand smoke was responsible for about 3,000 deaths a year in the United States. Singer promptly called it “junk science.” He warned that the EPA scientists were secretly pursuing a communist agenda. “If we do not carefully delineate the government’s role in regulating … dangers, there is essentially no limit to how much government can ultimately control our lives,” Singer wrote.

Reacting to the EPA study, the Philip Morris tobacco company spearheaded the establishment of “The Advancement of Sound Science Coalition” (TASSC). Its goal was to raise doubts about the risks of passive smoking and climate change, and its message was to be targeted at journalists — but only those with regional newspapers. Its express goal was “to avoid cynical reporters from major media.”

Singer, Marshall Institute founder Fred Seitz and Patrick Michaels, who is now one of the best known climate change skeptics, were all advisers to TASSC.

Not Proven

The Reagan administration also appointed Singer to a task force on acid rain. In that group, Singer insisted that it was too early to take action and that it hadn’t even been proven yet that sulfur emissions were in fact the cause. He also said that some plants even benefited from acid rain.

After acid rain, Singer turned his attention to a new topic: the “ozone scare.” Once again, he applied the same argumentative pattern, noting that although it was correct that the ozone concentration in the stratosphere was declining, the effect was only local. Besides, he added, it wasn’t clear yet whether chlorofluorocarbons (CFCs) from aerosol cans were even responsible for ozone depletion.

As recently as 1994, Singer claimed that evidence “suggested that stratospheric chlorine comes mostly from natural sources.” Testifying before the US Congress in 1996, he said there was “no scientific consensus on ozone depletion or its consequences” — even though in 1995 the Nobel Prize had been awarded to three chemists who had demonstrated the influence of CFCs on the ozone layer.

The Usual Suspects

Multinational oil companies also soon adopted the tried-and-true strategies of disinformation. Once again, lobbying groups were formed that were designed to look as scientific as possible. First there was the Global Climate Coalition, and then ExxonMobil established the Global Climate Science Team. One of its members was lobbyist Myron Ebell. Another one was a veteran of the TASCC tobacco lobby who already knew the ropes. According to a 1998 Global Climate Science Team memo: “Victory will be achieved when average citizens ‘understand’ (recognize) uncertainties in climate science.”

It soon looked as though there were a broad coalition opposing the science of climate change, supported by organizations like the National Center for Policy Analysis, the Heartland Institute and the Center for Science and Public Policy. In reality, these names were often little more than a front for the same handful of questionable scientists — and Exxon funded the whole illusion to the tune of millions of dollars.

It was an excellent investment.

In 2001, the administration of then-President George W. Bush reneged on previous climate commitments. After that, the head of the US delegation to the Kyoto negotiations met with the oil lobbyists from the Global Climate Coalition to thank them for their expertise, saying that President Bush had “rejected Kyoto in part based on input from you.”

Singer’s comrade-in-arms Patrick Michaels waged a particularly sharp-tongued campaign against the phalanx of climatologists. One of his books is called: “The Satanic Gases: Clearing the Air about Global Warming.” Michaels has managed to turn doubt into a lucrative business. The German Coal Association paid him a hefty fee for a study in the 1990s, and a US electric utility once donated $100,000 to his PR firm.

Inconsistent Arguments

Both Michaels and Ebell are members of the Cooler Heads Coalition. Unlike Singer and Seitz, they are not anti-communist crusaders from the Cold War era, but smooth communicators. Ebell, a historian, argues that life was not as comfortable for human beings in the Earth’s cold phases than in the warm ones. Besides, he adds, there are many indications that we are at the beginning of a cooling period.

The professional skeptics tend to use inconsistent arguments. Sometimes they say that there is no global warming. At other times, they point out that while global warming does exist, it is not the result of human activity. Some climate change deniers even concede that man could do something about the problem, but that it isn’t really much of a problem. There is only one common theme to all of their prognoses: Do nothing. Wait. We need more research.

People like Ebell cannot simply be dismissed as cranks. He has been called to testify before Congress eight times, and he unabashedly crows about his contacts at the White House, saying: “We knew whom to call.”

Ebell faces more of an uphill battle in Europe. In his experience, he says, Europe is controlled by elites who — unlike ordinary people — happen to believe in climate change.

Einstein on a Talk Show

But Fred Singer is doing his best to change that. He has joined forces with the European Institute for Climate and Energy (EIKE). The impressive-sounding name, however, is little more than a P.O. box address in the eastern German city of Jena. The group’s president, Holger Thuss, is a local politician with the conservative Christian Democratic Union (CDU).

Hans Joachim Schellnhuber, director of the respected Potsdam Institute for Climate Impact Research and an adviser to Chancellor Merkel on climate-related issues, says he has no objection to sharing ideas with the EIKE, as long as its representatives can stick to the rules of scientific practice. But he refuses to join EIKE representatives in a political panel discussion, noting that this is precisely what the group hopes to achieve, namely to create the impression among laypeople that experts are discussing the issues on a level playing field.

Ultimately, says Schellnhuber, science has become so complicated that large segments of the population can no longer keep up. The climate skeptics, on the other hand, are satisfied with “a desire for simple truths,” Schellnhuber says.

This is precisely the secret of their success, according to Schellnhuber, and unfortunately no amount of public debate can change that. “Imagine Einstein having to defend the theory of relativity on a German TV talk show,” he says. “He wouldn’t have a snowball’s chance in hell.”

>Do the IPCC use alarmist language?

By James Wight

Graham Wayne has recently written rebuttals to “The IPCC consensus is phony” and “IPCC is alarmist”. But, you might say, that’s only half the story – do the IPCC present their conclusions in an alarmist way? There are many different ways you might look at this, but one of the more important ones is how the IPCC present probabilities (or “likelihoods”).

Thinking about probability does not come intuitively to the human mind. Our assessment of a risk often depends on how the probability is presented.

Suppose you are about to get on a plane and a reliable source tells you that there is a 1% chance that the plane will crash during your flight. Do you still want to get on the plane? I’m guessing you’d be having second thoughts about it.

What if the probability of a crash is 1 in 20? 1 in 10? 1 in 3? You’d probably run away screaming.

I’ll get to the point of all this shortly, but please bear with me and consider the following quote from the IPCC’s Fourth Assessment Report (AR4):

“It is very unlikely that [Atlantic Ocean circulation] will undergo a large abrupt transition during the 21st century.” [Source]

Are you alarmed yet? Is this an example of the IPCC using alarmist language in reporting its conclusions?

To answer this question, you first have to understand what the IPCC are trying to say. In the introduction to the AR4 Synthesis Report, there is a detailed description of how uncertainty is treated in IPCC reports, and I don’t think the public appreciates just how un-alarmist it is. A 1% chance scarcely rates a mention: anything with such a low probability is described as “exceptionally unlikely”. A probability of 1 in 20 is considered to be “extremely unlikely”; 1 in 10 is “very unlikely”, and even 1 in 3 is still “unlikely”. Conversely, 2 in 3 is “likely”, 9 in 10 is “very likely”, 19 in 20 is “extremely likely”, and 99% is “virtually certain”.

So if you asked the IPCC to do a report on your plane trip, and the probability of a crash was smaller than 1 in 10, about half a decade later they’d get back to you with something like: “It is very unlikely that this plane will crash.” (Except that it would probably be a lot wordier than that.)

And when the IPCC says an abrupt transition in Atlantic Ocean circulation is “very unlikely”, they mean the same thing: the chance is less than 1 in 10. Yet you’re probably not running away screaming.

Most of the IPCC’s main conclusions are given a high degree of likelihood. Probably the most quoted sentence from the entire AR4 is:

“Most of the observed increase in global average temperatures since the mid-20th century is very likely due to the observed increase in anthropogenic greenhouse gas concentrations.” [Source]

Translation: the likelihood that humanity’s greenhouse gas emissions are causing global warming is greater than 9 in 10.

Another important conclusion (though not particularly new to the AR4) is this:

“[T]he equilibrium global mean [surface air temperature] warming for a doubling of atmospheric carbon dioxide (CO2), or ‘equilibrium climate sensitivity’, is likely to lie in the range 2°C to 4.5°C, with a most likely value of about 3°C. Equilibrium climate sensitivity is very likely larger than 1.5°C.” [Source]

Translation: the chances are 2 out of 3 that a doubling of atmospheric CO2 will warm the planet by between 2 and 4.5 degrees; 9 out of 10 that it will be more than 1.5 degrees.

One more IPCC quote:

“It is very likely that hot extremes, heat waves and heavy precipitation events will continue to become more frequent.” [Source]

That is, the chances of more extreme weather are higher than 9 in 10. If you’re thinking that wilder weather is not exactly as serious as a plane crash, then consider that over 20 million people have been affected by the 2010 Pakistan floods. This sort of extreme weather event will become more frequent with global warming. Do we, does humanity, really want to get on this plane?

The IPCC are not alarmist in their conclusions, and they are no more alarmist in the way they report their conclusions.

>Políticas públicas para mudanças climáticas (FAPESP)

Especiais

Por Fabio Reynol, de Campinas (SP)
18/10/2010

Agência FAPESP – Se o Estado de São Paulo fosse um país estaria em 39º no ranking das nações que mais emitem dióxido de carbono (CO2) na atmosfera. Em 2003, foram 83 milhões de toneladas do gás, praticamente um quarto do montante brasileiro.

Esses números lançam ao estado um enorme desafio para reduzir as emissões e já estimularam a implantação de várias políticas públicas, entre as quais a ativação do Conselho Estadual de Mudanças Climáticas, ocorrida na sexta-feira (15/10).

O tema foi tratado em mesa durante o fórum “Mudanças Climáticas Globais – Desafios e oportunidades de pesquisa”, realizado na Universidade Estadual de Campinas (Unicamp) nos dias 14 e 15 de outubro. A mesa teve a participação do diretor-presidente da Companhia Ambiental do Estado de São Paulo (Cetesb), Fernando Rei, do diretor científico da FAPESP, Carlos Henrique de Brito Cruz, e do diretor do Instituto de Estudos Avançados da Faculdade de Economia e Administração da USP, Jacques Marcovitch.

“As emissões de CO2 em São Paulo são tímidas em relação aos países desenvolvidos, mas, ao se considerar o índice de ocupação do solo, são emissões superiores à média nacional”, disse Rei.

O executivo fez um histórico das políticas públicas paulistas desde o Programa Estadual de Mudanças Climáticas do Estado de São Paulo (Proclima), lançado em 1995, e destacou a participação paulista em organizações internacionais de estados subnacionais, que englobam regiões internas de países como estados e províncias. “São Paulo é copresidente pela segunda vez da rede de Governos Regionais para o Desenvolvimento Sustentável”, destacou.

O Conselho Estadual de Mudanças Climáticas estava previsto na Lei Estadual 13.798, assinada em novembro de 2009, e possui uma estrutura tripartite: um terço de representantes do governo estadual, um terço vindo de governos municipais e um terço de membros da sociedade civil.

São Paulo também iniciou o Registro Público de Emissões a fim de identificar, por setores e por empresas, os maiores emissores de gases de efeito estufa. Todas essas medidas têm como objetivo tentar alcançar uma redução de 20% do CO2 emitido até o ano de 2020 em relação aos valores de 2005, meta que o Estado se comprometeu a cumprir.

“Trata-se de um objetivo extremamente difícil e que exigirá a participação da sociedade civil”, salientou Rei. No ano de 2005, São Paulo lançou na atmosfera 122 milhões de toneladas de CO2, o que significa que em 2020 poderia lançar até 98 milhões de toneladas, de acordo com a meta.

A tarefa é ainda mais complexa ao considerar que São Paulo já substituiu quase a metade das fontes energéticas de origem fóssil para fontes renováveis na última década, como ressaltou Brito Cruz. “Cerca de 60% do consumo de energia do estado era de origem fóssil e hoje esse índice é de apenas 33%”, disse.

O diretor científico da FAPESP focou na contribuição que a ciência deu ao longo da história à questão do clima, desde o matemático francês Jean Jacques Baptiste Fourier, que em 1827 publicou um artigo no qual concebeu o conceito de efeito estufa, até as experiências do norte-americano Charles Kelling, que de 1957 a 1972 escalou periodicamente o vulcão inativo Mauna Loa, no Havaí, para coletar amostras de ar e medir o teor de carbono da atmosfera.

“Foram pesquisas que pareciam inúteis em suas épocas e que hoje se mostram extremamente pertinentes em relação aos problemas que estamos enfrentando”, disse, destacando que o Painel Intergovernamental de Mudanças Climáticas (IPCC) foi criado pela Organização das Nações Unidas para que as lideranças políticas pudessem entender a produção científica a respeito do clima.

Brito Cruz também apresentou os principais pontos abordados pelo Programa FAPESP de Pesquisa sobre Mudanças Climáticas Globais (PFPMCG), que tem procurado intensificar a produção científica nacional no clima e conta com projetos em andamento em áreas como agronomia, química, geociências, demografia e economia.

“Não queremos apenas aumentar a quantidade dos trabalhos científicos, mas também a sua qualidade para que ganhem visibilidade internacional”, disse. Nesse sentido, a FAPESP financiou a compra de um supercomputador em parceria com a Financiadora de Estudos e Projetos (Finep) do Ministério da Ciência e Tecnologia.

A máquina está sendo instalada no Instituto Nacional de Pesquisas Espaciais (Inpe) em Cachoeira Paulista (SP) e será dedicada a processar modelos de simulação do clima.

O supercomputador deverá colocar o Brasil entre os maiores do mundo em investigação do clima e poderá processar modelos que contemplem os sistemas climáticos nacionais, como a Floresta Amazônica, a Mata Atlântica e o Cerrado.

Além do computador, Brito Cruz anunciou que a FAPESP também está financiando a compra de um barco e de um navio oceanográfico que deverão auxiliar pesquisas sobre a temperatura, acidificação e nível dos oceanos, entre outras pesquisas.

Aprimorar incentivos e aumentar sanções

Marcovitch falou sobre os impactos econômicos e a participação do setor empresarial no esforço para mitigar as mudanças climáticas. O professor, que foi reitor da USP entre 1997 e 2001, afirmou que é preciso respeitar o tempo de ação de cada ator social para que o esforço conjunto funcione.

“As pautas de cada um são diferentes: membros do governo enfatizam o poder, cientistas se pautam na busca pela verdade, empresas focam no resultado e a sociedade civil trabalha com valores. É preciso enxergar isso para haver o diálogo e avançar”, disse.

No caso do setor empresarial, Marcovitch defende políticas públicas que promovam incentivos mais eficientes para as companhias que participarem e, ao mesmo tempo, sanções mais rigorosas para aquelas que não quiserem colaborar.

Por fim, o pesquisador apresentou partes do Estudo Econômico das Mudanças Climáticas no Brasil, que coordenou junto a 11 instituições.

O trabalho procurou identificar as vulnerabilidades que a economia e a sociedade brasileira possuem em relação às alterações do clima. “Os países que promoveram os maiores saltos da civilização foram os mais ousados e que enfrentaram grandes desafios, a área do clima é um deles”, disse.

05 Oct 2010: Analysis

As climate science advances, predictions about the extent of future warming and its effects are likely to become less — not more — precise. That may make it more difficult to convince the public of the reality of climate change, but it hardly diminishes the urgency of taking action.

by Fred Pearce

I think I can predict right now the headlines that will follow publication of the next report from the Intergovernmental Panel on Climate Change (IPCC), due in 2013. “Climate scientists back off predicting rate of warming: ‘The more we know the less we can be sure of,’ says UN panel.”

That is almost bound to be the drift if two-time IPCC lead author Kevin Trenberth and others are right about what is happening to the new generation of climate models. And with public trust in climate science on the slide after the various scandals of the past year over e-mails and a mistaken forecast of Himalayan ice loss, it hardly seems likely scientists will be treated kindly.

It may not matter much who is in charge at the IPCC by then: Whether or not current chairman Rajendra Pachauri keeps his job, the reception will be rough. And if climate negotiators have still failed to do a deal to replace the Kyoto Protocol, which lapses at the end of 2012, the fallout will not be pretty, either diplomatically or climatically.

Clearly, concerns about how climate scientists handle complex issues of scientific uncertainty are set to escalate. They were highlighted in a report about IPCC procedures published in late August in response to growing criticism about IPCC errors. The report highlighted distortions and exaggerations in IPCC reports, many of which involved not correctly representing uncertainty about specific predictions.

“The latest climate modeling runs are trying to deal with a range of factors not dealt with in the past.”

But efforts to rectify the problems in the next IPCC climate-science assessment (AR5) are likely to further shake public confidence in the reliability of IPCC climate forecasts.

Last January, Trenberth, head of climate analysis at the National Center for Atmospheric Research in Boulder, Colo., published a little-noticed commentary in Nature online. Headlined “More Knowledge, Less Certainty,” it warned that “the uncertainty in AR5’s predictions and projections will be much greater than in previous IPCC reports.” He added that “this could present a major problem for public understanding of climate change.” He can say that again.

This plays out most obviously in the critical estimate of how much warming is likely between 1990, the baseline year for most IPCC work, and 2100. The current AR4 report says it will be between 1.8 and 4.0 degrees Celsius (3 to 7 degrees F). But the betting is now that the range offered next time will be wider, especially at the top end.

The public has a simple view about scientific uncertainty. It can accept that science doesn’t have all the answers, and that scientists try to encapsulate those uncertainties with devices like error bars and estimates of statistical significance. What even the wisest heads will have trouble with, though, is the notion that greater understanding results in wider errors bars than before.

Trenberth explained in his Nature commentary why a widening is all but certain. “While our knowledge of certain factors [responsible for climate change] does increase,” he wrote, “so does our understanding of factors we previously did not account for or even recognize.” The trouble is this sounds dangerously like what Donald Rumsfeld, in the midst of the chaos of the Iraq War, famously called “unknown unknowns.” I would guess that the IPCC will have even less luck than he did in explaining what it means by this.

The latest climate modeling runs are trying to come to grips with a range of factors ignored or only sketchily dealt with in the past. The most troubling is the role of clouds. Clouds have always been recognized as a ticking timebomb in climate models, because nobody can work out whether warming will change them in a way that amplifies or moderates warming — still less how much. And their influence could be very large. “Clouds remain one of the largest uncertainties in the climate system’s response to temperature changes,” says Bruce Wielicki, a scientist at NASA’s Langley Research Center who is investigating the impact of clouds on the Earth’s energy budget.

An added problem in understanding clouds is the role of aerosols from industrial smogs, which dramatically influence the radiation properties of clouds. “Aerosols are a mess,” says Thomas Charlock, a senior scientist at the Langley Research Center and co-investigator in a NASA project known as Clouds and the Earth’s Radiant Energy System (CERES). “We don’t know how much is out there. We just can’t estimate their influence with calculations alone.”

“Despite much handwringing, the IPCC has never worked out how to make sense of uncertainty.”

Trenberth noted in Nature, “Because different groups are using relatively new techniques for incorporating aerosol effects into the models, the spread of results will probably be much larger than before.”

A second problem for forecasting is the potential for warming to either enhance or destabilize existing natural sinks of carbon dioxide and methane in soils, forests, permafrost, and beneath the ocean. Again these could slow warming through negative feedbacks or — more likely, according to recent assessments — speed up warming, perhaps rather suddenly as the planetary system crosses critical thresholds.

The next models will be working hard to take these factors into better account. Whether they go as far as some preliminary runs published in 2005, which suggested potential warming of 10 degrees C (18 degrees F) or more is not clear. Of course, uncertainty is to be expected, given the range of potential feedbacks that have to be taken into account. But it is going to be hard to explain why, when you put more and better information into climate models, they do not home in on a more precise answer.

Yet it will be more honest, says Leonard Smith, a mathematician and statistician at the University of Oxford, England, who warns about the “naive realism” of past climate modeling. In the past, he says, models have been “over-interpreted and misinterpreted. We need to drop the pretense that they are nearly perfect. They are getting better. But as we change our predictions, how do we maintain the credibility of the science?”

The only logical conclusion for a confused and increasingly wary public may be that if the error bars were wrong before, they cannot be trusted now. If they do not in some way encapsulate the “unknowns,” what purpose do they have?

Despite much handwringing, the IPCC has never worked out how to make sense of uncertainty. Take the progress of those errors bars in assessing warming between 1990 and 2100.

The panel’s first assessment, published back in 1990, predicted a warming of 3 degrees C by 2100, with no error bars. The second assessment, in 1995, suggested a warming of between 1 and 3.5 degrees C. The third, in 2001, widened the bars to project a warming of 1.4 to 5.8 degrees C. The fourth assessment in 2007 contracted them again, from 1.8 to 4.0 degrees C. I don’t think the public will be so understanding if they are widened again, but that now seems likely.

Trenberth is nobody’s idea of someone anxious to rock the IPCC boat. He is an IPCC insider, having been lead author on key chapters in both 2001 and 2007, and recently appointed as a review editor for AR5. Back in 2005 he made waves by directly linking Hurricane Katrina to global warming. But in the past couple of years he has taken a growing interest in highlighting uncertainties in the climate science.

Late last year, bloggers investigating the “climategate” emails highlighted a message he sent to colleagues in which he said it was a “travesty” that scientists could not explain cool years like 2008. His point, made earlier in the journal Current Opinion in Environmental Stability, was that “it is not a sufficient explanation to say that a cool year is due to natural variability.” Such explanations, he said, “do not provide the physical mechanisms involved.” He wanted scientists to do better.

“Trenberth questioned if the IPCC wouldn’t be better off getting out of the prediction business.”

In his Nature commentary, Trenberth wondered aloud whether the IPCC wouldn’t be better off getting out of the prediction business. “Performing cutting edge science in public could easily lead to misinterpretation,” he wrote. But the lesson of climategate is that efforts to keep such discussion away from the public have a habit of backfiring spectacularly.

All scientific assessments have to grapple with how to present uncertainties. Inevitably they make compromises between the desire to convey complexity and the need to impart clear and understandable messages to a wider public. But the IPCC is caught on a particular dilemma because its founding purpose, in the late 1980s, was to reach consensus on climate science and report back to the world in a form that would allow momentous decisions to be taken. So the IPCC has always been under pressure to try to find consensus even where none exists. And critics argue that that has sometimes compromised its assessments of uncertainty.

The last assessment was replete with terms like “extremely likely” and “high confidence.” Critics charged that they often lacked credibility. And last August’s blue-chip review of the IPCC’s performance, by the InterAcademy Council, seemed to side with the critics.

The council’s chairman, Harold Shapiro of Princeton, said existing IPCC guidelines on presenting uncertainty “have not been consistently followed.” In particular, its analysis of the likely impacts of climate change “contains many statements that were assigned high confidence but for which there is little evidence.” The predictions were not plucked from the air. But the charge against the IPCC is that its authors did not always correctly portray the uncertainty surrounding the predictions or present alternative scenarios.

“We need to get used to greater uncertainty in imagining exactly how climate change will play out.”

The most notorious failure was the claim that the Himalayan glaciers could all have melted by 2035. This was an egregious error resulting from cut-and-pasting a non-peer reviewed claim from a report by a non-governmental organization. So was a claim that 55 percent of the Netherlands lies below sea level. But other errors were failures to articulate uncertainties. The study highlighted a claim that even a mild loss of rainfall over the Amazon could destroy 40 percent of the rainforest, though only one modeling study has predicted this.

Another headline claim in the report, in a chapter on Africa, was that “projected reductions in [crop] yield in some countries could be as much as 50 percent by 2020.” The only source was an 11-page paper by a Moroccan named Ali Agoumi that covered only three of Africa’s 53 countries (Morocco, Tunisia, and Algeria) and had not gone through peer review. It simply asserted that “studies on the future of vital agriculture in the region have shown… deficient yields from rain-based agriculture of up to 50 percent during the 2000-2020 period.” No studies were named. And even Agoumi did not claim the changes were necessarily caused by climate change. In fact, harvests in North Africa already differ by 50 percent or more from one year to the next, depending on rainfall. In other words, Agoumi’s paper said nothing at all about how climate change might or might not change farm yields across Africa. None of this was conveyed by the report.

In general, the InterAcademy Council’s report noted a tendency to “emphasise the negative impacts of climate change,” many of which were “not supported sufficiently in the literature, not put into perspective, or not expressed clearly.” Efforts to eliminate these failings will necessarily widen the error bars on a range of predictions in the next assessment.

We are all — authors and readers of IPCC reports alike — going to have to get used to greater caution in IPCC reports and greater uncertainty in imagining exactly how climate change will play out. This is probably healthy. It is certainly more honest. But it in no way undermines the case that we are already observing ample evidence that the world is on the threshold of profound and potentially catastrophic warming. And it in no way undermines the urgent need to do something to halt the forces behind the warming.

Some argue that scientific uncertainty should make us refrain from action to slow climate change. The more rational response, given the scale of what we could face, is the precise opposite.

How the Senate and the White House missed their best chance to deal with climate change.

by Ryan Lizza October 11, 2010

Lindsey Graham, Joseph Lieberman, and John Kerry each sought a kind of redemption through climate-change legislation.

On April 20, 2010, Senators John Kerry, Lindsey Graham, and Joseph Lieberman, along with three aides, visited Rahm Emanuel, President Obama’s chief of staff, at the White House. The legislators had spent seven months writing a comprehensive bill that promised to transform the nation’s approach to energy and climate change, and they were planning a press conference in six days to unveil their work.

Kerry, of Massachusetts, Graham, of South Carolina, and Lieberman, of Connecticut, had become known on Capitol Hill as the Three Amigos, for the Steve Martin comedy in which three unemployed actors stumble their way into defending a Mexican village from an armed gang. All had powerful personal motivations to make the initiative work. Kerry, who has been a senator for twenty-five years and has a long record of launching major investigations, had never written a landmark law. Lieberman, an Independent who had endorsed John McCain for President, had deeply irritated his liberal colleagues by helping the Republicans weaken Obama’s health-care bill. Graham, a Republican, had a reputation as a Senate maverick—but not one who actually got things done. This bill offered the chance for all three men to transform their reputations.

The senators had cobbled together an unusual coalition of environmentalists and industries to support a bill that would shift the economy away from carbon consumption and toward environmentally sound sources of energy. They had the support both of the major green groups and of the biggest polluters. No previous climate-change legislation had come so far. Now they needed the full support of the White House.

The senators sat around the conference table in the corner of Emanuel’s office. In addition to the chief of staff, they were joined by David Axelrod, the President’s political adviser, and Carol Browner, the assistant to the President for Energy and Climate Change. Lieberman introduced his aide, Danielle Rosengarten, to Emanuel.

“Rosengarten working for Lieberman,” Emanuel said. “Shocker!”

Kerry, Graham, and Lieberman knew that Obama’s advisers disagreed about climate-change legislation. Browner was passionate about the issue, but she didn’t have much influence. Axelrod, though influential, was not particularly committed. Emanuel prized victory above all, and he made it clear that, if there weren’t sixty votes to pass the bill in the Senate, the White House would not expend much effort on the matter. The Democrats had fifty-nine members in their caucus, but several would oppose the bill.

“You’ve had all these conversations, you’ve been talking with industry,” Emanuel said. “How many Republicans did you bring on?”

Kerry, the de-facto leader of the triumvirate, assured him that there were five Republicans prepared to vote for the bill. One of them, Lindsey Graham, was sitting at the table. Kerry listed four more: Susan Collins, Olympia Snowe, Scott Brown, and George LeMieux. With five Republicans, getting sixty votes would be relatively easy. The Obama White House and the Three Amigos would be known for having passed a bill that would fundamentally change the American economy and slow the emission of gases that are causing the inexorable, and potentially catastrophic, warming of the planet.

The Senate coalition that introduced the bill started to form in early 2009, when Lieberman instructed Rosengarten to work with the office of John McCain, Lieberman’s longtime partner on the issue. As the newest member of Lieberman’s staff, she was in charge of his climate portfolio, and Lieberman made a simple and oft-repeated demand: “Get me in the room.”

Lieberman had worked on climate change since the nineteen-eighties, and in recent years he had introduced three global-warming bills. He also had long been interested in a pollution-control mechanism called cap-and-trade. The government would set an over-all limit on emissions and auction off permission slips that individual polluters could then buy and sell.

By late January, 2009, the details of the Lieberman-McCain bill had been almost entirely worked out, and Lieberman began showing it to other Senate offices in anticipation of a February press conference. The goal was to be the centrist alternative to a separate effort, initiated by Barbara Boxer, a liberal from California and the chair of the Environment and Public Works Committee.

But the negotiations stalled as the bill moved forward. In Arizona, a right-wing radio host and former congressman, J. D. Hayworth, announced that he was considering challenging McCain in the primary. McCain had never faced a serious primary opponent for his Senate seat, and now he was going to have to defend his position on global warming to hard-core conservative voters. The Republican Party had grown increasingly hostile to the science of global warming and to cap-and-trade, associating the latter with a tax on energy and more government regulation. Sponsoring the bill wasn’t going to help McCain defeat an opponent to his right.

By the end of February, McCain was starting to back away from his commitment to Lieberman. At first, he insisted that he and Lieberman announce a set of climate-change “principles” instead of a bill. Then, three days before a scheduled press conference to announce those principles, the two senators had a heated conversation on the Senate floor. Lieberman turned and walked away. “That’s it,” he told an aide. “He can’t do it this year.”

In Barack Obama’s primary-campaign victory speech, in St. Paul, Minnesota, he said that his election would be a historical turning point on two pressing issues: health care and climate change. “We will be able to look back and tell our children that this was the moment when we began to provide care for the sick,” he said. “When the rise of the oceans began to slow and our planet began to heal.” During the campaign, he often argued that climate change was an essential part of a national energy strategy. “Energy we have to deal with today,” Obama said in a debate with McCain. “Health care is priority No. 2.”

After the election, Obama decided to work on both issues simultaneously. Representative Henry Waxman moved climate change through the House, while Max Baucus, of Montana, moved health care in the Senate. “The plan was to throw two things against the wall, and see which one looks more promising,” a senior Administration official said. Obama, in a February, 2009, address to Congress, said, “To truly transform our economy, protect our security, and save our planet from the ravages of climate change, we need to ultimately make clean, renewable energy the profitable kind of energy. So I ask this Congress to send me legislation that places a market-based cap on carbon pollution.”

In March of 2009, a senior White House official outlined a strategy for a “grand bargain,” in which Democrats would capitulate to Republicans on some long-cherished environmental beliefs in exchange for a cap on carbon emissions. “You need to have something like T. Boone Pickens and Al Gore holding hands,” the White House official told me. In exchange for setting a cap on emissions, Democrats would agree to an increase in the production of natural gas (the only thing that Pickens, the Texas oil-and-gas billionaire, cared about), nuclear power, and offshore oil. If Republicans didn’t respond to the proposed deals, the White House could push them to the table by making a threat through the Environmental Protection Agency, which had recently been granted power to regulate carbon, just as it regulates many other air pollutants.

The strategy had risks, including the possibility that expanded drilling off America’s coast could lead to a dangerous spill. But Browner, the head of the E.P.A. for eight years under Clinton, seemed to think the odds of that were limited. “Carol Browner says the fact of the matter is that the technology is so good that after Katrina there was less spillage from those platforms than the amount you spill in a year filling up your car with gasoline,” the White House official said. “So, given that, she says realistically you could expand offshore drilling.”

The day after the confrontation with McCain, Lieberman met with Browner in his office to discuss strategy. Perhaps sensing that Boxer would have a hard time gaining Republican support, Browner assured Lieberman that he would be “absolutely central” to passing a climate bill. Lieberman was flattered. As Waxman moved cap-and-trade through the House that spring and summer and Boxer prepared to write her version of the bill, Lieberman and his aides met with forty senators or their staffs, to assess their concerns and to develop ideas about his role in Browner’s strategy.

Lieberman knew that the issue was almost as much regional as ideological. When he went to lobby Evan Bayh, of Indiana, Bayh held up a map of the United States showing, in varying shades of red, the percentage of electricity that each state derived from burning coal, the main source of greenhouse-gas emissions in the United States. The more coal used, the redder the state and the more it would be affected by a cap on carbon. The Northeast, the West Coast, and the upper Northwest of the country were pale. But the broad middle of the country—Pennsylvania, West Virginia, Ohio, Kentucky, Indiana, Illinois—was crimson. (Indiana, for example, derives ninety-four per cent of its electricity from coal). “Every time Senator Lieberman would open his mouth, Bayh would show him the map,” a Lieberman aide said.

It often took some work to figure out what, above all else, each senator cared about. In Senate parlance, this is known as the “top ask,” and after every meeting Rosengarten compiled a list for Lieberman. The top ask of Senator Debbie Stabenow, of Michigan, was to insure that incentives given to farmers for emissions-reducing projects—known as “offsets”—would be decided in part by the U.S.D.A., and not just the E.P.A. “Ultimately, farmers aren’t crazy about letting hippies tell them how to make money,” Rosengarten said. Blanche Lincoln, of Arkansas, told Lieberman that she had a major oil refiner in her state—Murphy Oil—and she wanted to make sure that any cap-and-trade bill protected it.

Lieberman knew that he would need a Republican for every Democrat he lost. Like the White House, he concluded that significant subsidies for the nuclear-power industry could win Republican support. Lieberman coaxed nine Republicans into forming a group to write nuclear legislation that could be merged with whatever climate bill emerged from Boxer’s committee. By not automatically resisting everything connected to Obama, these senators risked angering Mitch McConnell, the Republican leader and architect of the strategy to oppose every part of Obama’s agenda, and the Tea Party movement, which seemed to be gaining power every day. The senators also knew, however, that they could exercise enormous influence on the legislation—and that their top asks would be granted.

George Voinovich, of Ohio, told both Harry Reid, the Senate Majority Leader, and Lieberman that the right nuclear language could win his vote, so Lieberman used a nuclear bill that Voinovich’s staff was drafting as the framework for the group. Lindsey Graham, who grew up in Central, South Carolina, near a nuclear plant, wanted tax incentives and loan guarantees to help the nuclear industry.

Meanwhile, the House bill, known as Waxman-Markey (for Edward J. Markey, of Massachusetts), passed on June 26, 2009, by a vote of 219-212. Eight Republicans supported it. But there were omens for the Senate. The White House and Waxman spent the final days before the vote negotiating with members of the House representing two crucial interest groups: coal and agriculture. Despite cutting generous deals, they ended up with only limited support. Worse, several members who had promised House Speaker Nancy Pelosi their votes reneged. One of them, Ciro Rodriguez, of Texas, ducked into the chamber, quickly cast a no vote, and then sprinted out. Anthony Weiner, a Brooklyn Democrat and one of Pelosi’s whips, chased after him, yelling, “Ciro! Ciro!”

As the scene unfolded on the floor, Rosengarten and other Senate aides watched from the gallery. Rosengarten turned to a colleague and said, “Now it’s our turn. We’ve got to go pass this thing in the Senate.”

When the Obama era began, John Kerry was looking for a new political identity. Like Lieberman, he had a strained relationship with the new President. Kerry had been scheduled to endorse Obama the day after Obama’s presumed victory in the New Hampshire primary. But Obama lost, and that night he nervously called Kerry and asked, “Are you still on board?” Kerry said he was. “Ninety-nine per cent of politicians would have walked away at that moment, because our odds of winning the primaries were quite low,” Dan Pfeiffer, now Obama’s communications director, told me in a 2008 interview. “It was a huge moment.” Kerry and his aides believed that, if Obama was the President, Kerry’s endorsement would give him the inside track in the competition for the job as Secretary of State. But Obama passed him over.

Kerry, as the chairman of the Foreign Relations Committee, could help steer the Administration’s foreign policy, but he wanted to play a big role in shaping Obama’s domestic agenda. In 2007, he had written a book about environmental activism, “This Moment on Earth,” and the issue was a rare one in which the junior senator from Massachusetts had a deeper interest than the senior senator, Ted Kennedy. For most of their quarter century together in the Senate, Kennedy was the legislator (the Americans with Disabilities Act, State Children’s Health Insurance Program, No Child Left Behind), and Kerry was the investigator (P.O.W.s in Vietnam, B.C.C.I., Iran-Contra). Now that could change. “This was Kerry’s opportunity to prove that he could be in a major, really historic piece of legislation,” Lieberman said.

At first, Kerry joined forces with Barbara Boxer, and spent months trying to find a Republican co-sponsor for her bill, which was almost a carbon copy of Waxman-Markey. In August, Rosengarten was eating lunch with Kerry’s climate-policy aide, Kathleen Frangione, at Sonoma, a Capitol Hill wine bar. Rosengarten said she had spent hours working on the nuclear legislation with Graham’s policy aide, Matthew Rimkunas, and she was shocked by something he had recently told her: Graham would have backed a climate-change bill that Lieberman had co-sponsored in 2007 if it had included the language supportive of nuclear power that they had just worked out. Kerry and Graham had to talk. Perhaps Kerry could split off from Boxer and try to work with Graham on a bipartisan bill.

Within days, Kerry and Graham were meeting in Kerry’s office to negotiate the language of a Times Op-Ed piece announcing their partnership. As they talked, Kerry suddenly found himself having to reassess his convictions on oil drilling, nuclear energy, and environmental regulations with someone he barely knew and whom he had reason not to like. In 2004, Graham had gratuitously told the Times that Kerry “has no charisma” and “doesn’t relate well to average people.” But the two men agreed that their eventual bill would have to help the nuclear industry and expand oil drilling. As they wrote the article, Graham introduced a third issue: revoking the E.P.A.’s authority to regulate greenhouse gases. Kerry was furious, but he eventually relented. The Op-Ed would include language signalling to insiders that E.P.A. authority would be curtailed: “Industry needs the certainty that comes with congressional action.”

The article ran on October 11th. The next day, Graham was holding a town-hall meeting in the gym of a high school in Greenville, South Carolina. His constituents were not happy. One man accused him of “making a pact with the Devil.” Another shouted, “No principled compromise!” One audience member asked, “Why do you think it’s necessary to get in bed with people like John Kerry?” Graham, dressed in a blue blazer and khakis, paced the floor, explaining that there were only forty Republicans in the Senate, which meant that he had to work with the sixty Democrats. A man in the bleachers shouted, “You’re a traitor, Mr. Graham! You’ve betrayed this nation and you’ve betrayed this state!”

Soon afterward, Graham called Lieberman. He was concerned that Kerry might drag him too far to the left, and he knew that Lieberman, a close friend with whom he had travelled during McCain’s Presidential campaign, could serve as a moderating force. Graham may not have remembered that Kerry and Lieberman had, according to a Senate aide, “a tense personal relationship.” (Lieberman and Kerry ran against each other for President in 2004. In 2006, Kerry endorsed and campaigned for Lieberman’s Democratic opponent in his Senate race.) “I’m happy to try and negotiate a bill with Kerry,” Graham told Lieberman. “But I really want you in the room.”

On October 28, 2009, Graham was eating dinner at the Capital Grille, an expense-account steakhouse on Pennsylvania Avenue, with Fred Krupp, the president of the Environmental Defense Fund, and Rick Davis, a Republican consultant who had managed McCain’s two Presidential campaigns. The E.D.F., virtually alone among green groups in trying to form bonds with Republicans, prides itself on being the most politically sophisticated environmental organization in Washington. Krupp, who has short gray hair and a Brooks Brothers look that announces his disdain for hemp-wearing environmental activists, had helped to educate McCain on climate change, and the two men became close. Now he wanted to do the same for Graham. He called Davis, who was an E.D.F. board member, and arranged the dinner.

Graham came to the issue strictly as a dealmaker. He saw the Democrats’ interest in capping carbon emissions as an opportunity to boost the nuclear industry and to expand oil drilling. But now Krupp explained the basics of global-warming science and policy: how carbon trading worked, how farmers could use offsets to earn an income from growing trees, and how different lobbyists would affect the debate. Krupp told Graham that the crucial feature of the policy was the hard cap on emissions. The House bill required American carbon emissions to be seventeen per cent below 2005 levels by 2020. As long as that number held, environmentalists would show flexibility on most other issues. The dinner lasted three hours. The next day, Kerry, Graham, and Lieberman held their first meeting as the triumvirate that became known to everyone following the debate as K.G.L.

Heckled at home, Graham began to enjoy a new life as a Beltway macher. “Every lobbyist working on the issue wanted time with him, because suddenly it became clear that he could be the central person in the process,” Krupp recalled. All sectors of the economy would be affected by putting a price on carbon, and Graham’s campaign account started to grow. In 2009, he raised nothing from the electric-utility PACs and just fourteen thousand four hundred and fifty dollars from all PACs. In the first quarter of 2010 alone, the utilities sent him forty-nine thousand dollars. Krupp introduced Graham to donors in New York connected to the E.D.F. On December 7th, Julian Robertson, an E.D.F. board member and a hedge-fund billionaire, hosted Graham at a small gathering in his Manhattan apartment. Some New York guests gave money directly to Graham’s campaign account. Others, at Krupp’s suggestion, donated to a new group called South Carolina Conservatives for Energy Independence, which ran ads praising Graham in his home state.

For years, Graham had lived in McCain’s shadow. But, as the rebellious politics of 2010 transformed McCain into a harsh partisan, Graham adopted McCain’s old identity as the Senate’s happy moderate. To Graham’s delight, on December 23rd Time posted an online article headlined “LINDSEY GRAHAM: NEW GOP MAVERICK IN THE SENATE.” The photograph showed Graham standing at a lectern with Lieberman and Kerry.

McCain, worried about his reëlection, had been throwing rocks from the sidelines as the cap-and-trade debate progressed. When Waxman-Markey passed, he Tweeted that it was a “1400 page monstrosity.” A month after K.G.L. was formed, McCain told Politico, “Their start has been horrendous. Obviously, they’re going nowhere.” After the Time piece appeared, he was enraged. Graham told colleagues that McCain had called him and yelled at him, incensed that he was stealing the maverick mantle. “After that Graham story came out, McCain completely stopped talking to me,” Jay Newton-Small, the author of the Time piece, said.

Other Republican colleagues taunted Graham. “Hey, Lindsey,” they would ask, “how many times have you talked to Rahm today?,” and the criticisms in South Carolina became more intense. But Graham gave every indication to Lieberman and Kerry that he could deal with the pressure. He wasn’t up for reëlection until 2014, and his conversations with them, and with Krupp, the White House, and the Manhattan environmentalists, seemed to be having an impact. At a climate-change conference in South Carolina on January 5, 2010, Graham started to sound a little like Al Gore. “I have come to conclude that greenhouse gases and carbon pollution” are “not a good thing,” Graham said. He insisted that nobody could convince him that “all the cars and trucks and plants that have been in existence since the Industrial Revolution, spewing out carbon day in and day out,” could be “a good thing for your children and the future of the planet.” Environmentalists swooned. “Graham was the most inspirational part of that triumvirate throughout the fall and winter,” Michael Brune, the executive director of the Sierra Club, said. “He was advocating for strong action on climate change from an ethical and a moral perspective.”

But, back in Washington, Graham warned Lieberman and Kerry that they needed to get as far as they could in negotiating the bill “before Fox News got wind of the fact that this was a serious process,” one of the people involved in the negotiations said. “He would say, ‘The second they focus on us, it’s gonna be all cap-and-tax all the time, and it’s gonna become just a disaster for me on the airwaves. We have to move this along as quickly as possible.’ ”

In early December of 2009, Lieberman’s office approached Jay Heimbach, the White House official in charge of monitoring the Senate climate debate. For Obama, health care had become the legislation that stuck to the wall. As a consequence of the long debate over that issue, climate change became, according to a senior White House official, Obama’s “stepchild.” Carol Browner had just three aides working directly for her. “Hey, change the entire economy, and here are three staffers to do it!” a former Lieberman adviser noted bitterly. “It’s a bit of a joke.” Heimbach attended meetings with the K.G.L. staffers but almost never expressed a policy preference or revealed White House thinking. “It’s a drum circle,” one Senate aide lamented. “They come by, ‘How are you feeling? Where do you think the votes are? What do you think we should do?’ It’s never ‘Here’s the plan, here’s what we’re doing.’ ”

Lieberman’s office proposed to Heimbach that the first element of the bill to negotiate was the language about oil drilling. Lieberman and Graham believed it would send a clear message to Republicans and moderate Democrats that there were parts of the bill they would support. Heimbach favored doing anything to attract Republicans, and, though he wouldn’t take any specific actions, he generally supported the strategy.

Graham asked Senator Lisa Murkowski, of Alaska, to write the drilling language. Murkowski was up for reëlection and would soon be facing a primary against a Sarah Palin-backed Tea Party candidate. Her price for considering a climate-change bill with John Kerry’s name attached to it was high: she handed over a set of ideas for drastically expanding drilling, which included a provision to open the Arctic National Wildlife Refuge to oil companies. Democrats had spent decades protecting ANWR, and even Graham didn’t support drilling there. But he passed the Murkowski language on to his colleagues to see how they would react.

The K.G.L. coalition had two theories about how to win over Republicans and moderate Democrats. One was to negotiate directly with them and offer them something specific for their support. After a year of that method, the coalition had one Republican, and its next most likely target wanted to drill in ANWR. Other Republicans were slipping away. Shortly before Thanksgiving, George LeMieux, of Florida, approached Graham in the Senate gym and expressed interest in joining K.G.L. “Let me teach you something about this town,” Graham told him. “You can’t come that easy.” Graham was trying to give the new senator some advice, according to aides involved with the negotiations: LeMieux would be foolish to join the effort without extracting something for himself.

But LeMieux didn’t have the chance to try that, as he soon became another casualty of Republican primary politics. He had been appointed by the Florida governor, Charlie Crist, who was then running in a tight Republican primary for the seat against another Tea Party favorite, Marco Rubio. LeMieux couldn’t do anything that would complicate Crist’s life. In a private meeting with the three senators in December, he told them that he couldn’t publicly associate himself with the bill. But, according to someone who was present, he added, “My heart’s with you.”

As for Olympia Snowe, the moderate Republican from Maine, who was known for stringing Democrats along for months with vague promises of joining their legislative efforts, she seemed to have a new demand every time Kerry, Graham, and Lieberman sat down with her. She also made it clear that granting her wishes—everything from exempting home heating oil from greenhouse-gas regulations and permanently protecting Georges Bank, a Maine fishery, from drilling—would not guarantee her support. She had used similar tactics to win concessions in Obama’s health-care bill, which she eventually voted against. “She would always say that she was interested in working on it,” a person involved in the negotiations said, “but she would never say she was with us.”

Another prospect was Susan Collins, the other Republican from Maine. She was the co-sponsor of a separate climate bill, with Maria Cantwell, a Democrat from Washington. Their bill, known as “cap-and-dividend”—the government would cap carbon emissions and use revenue from polluters to compensate taxpayers for energy-rate hikes—gained some environmental support. Kerry, Graham, and Lieberman believed that the bill was unworkable and was stealing valuable attention from their effort. They spent months trying to figure out how to kill it and win over Collins. Eventually, Graham and Lieberman’s offices devised a ruse: they would adopt a crucial part of the Cantwell-Collins bill on market regulation in the official bill. Then they would quietly swap it out as the legislation made its way to the Senate floor. Collins, however, never budged.

The second theory about how to win the Republicans’ support was to go straight to their industry backers. If the oil companies and the nuclear industry and the utilities could be persuaded to support the legislation, then they would lobby Republicans. Rosengarten called the strategy “If you build it, they will come.” This was the strategy Obama used to pass health care. He sent his toughest political operatives—like Rahm Emanuel and Jim Messina—to cut deals with the pharmaceutical industry and hospitals, which at key points refrained from attacking the bill. (The pharmaceutical industry actually ran ads thanking Harry Reid for passing the bill.) In early 2010, K.G.L. shifted its focus from the Senate to industry.

On January 20, 2010, the three senators sat down in Kerry’s office with Tom Donohue, the president of the Chamber of Commerce, perhaps the most influential interest group in Washington. Donohue, who has headed the Chamber since 1997, had in that period helped kill several attempts to pass climate-change legislation.

In most K.G.L. meetings, Kerry led off with some lengthy remarks. “He opened every meeting we had with a ten- to thirty-minute monologue on climate change,” one of the aides involved said. “Just whatever was on his mind. There were slight variations. But never did the variations depend on the person we were meeting with.”

That day, Kerry had something specific to offer: preëmption from carbon being regulated by the E.P.A. under the Clean Air Act, with few strings attached. Kerry asked Donohue if that was enough to get the Chamber to the table. “We’ll start working with you guys right now,” Donohue said. It was a promising beginning. Soon afterward, Rosengarten and two of Donohue’s lobbyists worked out the legislative text on preëmption. The Chamber was allowed to write the language of its top ask into the bill. It turned out that working with Washington interest groups was far simpler than dealing with Republican senators navigating a populist conservative uprising.

Three weeks later, Kerry and some aides were in his office discussing the progress of their bill. Someone mentioned T. Boone Pickens, the author of the so-called Pickens Plan, an energy-independence proposal centered on enormous government subsidies for natural gas, which is abundant, cleaner-burning than other fossil fuels, and sold by a Pickens-controlled corporation at some two hundred natural-gas fuelling stations across North America. Back in 2004, Pickens had helped to fund the Swift Boat Veterans for Truth, a group that ran a sleazy—and inaccurate—ad campaign proclaiming, among other things, that Kerry had lied about the circumstances that led to his Bronze Star and Purple Hearts.

Kerry had an inspiration. “I’m going to call T. Boone,” he said. Frangione was surprised. “You really want to call that guy?” she asked. Kerry told an aide to get Pickens on the phone. Minutes later, Kerry was inviting Pickens to Washington to talk. Rosengarten, who watched Kerry make the call, thought it was “a show of extraordinary leadership.” The following week, Pickens and Kerry sat in two upholstered chairs in the Senator’s office. Between them loomed a giant model of Kerry’s Vietnam swift boat. Kerry walked Pickens through the components of the bill that he and his colleagues were writing, but Pickens seemed uninterested. He had just one request: include in the climate legislation parts of a bill that Pickens had written, called the Natural Gas Act, a series of tax incentives to encourage the use of natural-gas vehicles and the installation of natural-gas fuelling stations. In exchange, Pickens would publicly endorse the bill. At the end of the meeting, the Senator shook hands with the man who had probably cost him the Presidency. Afterward, staffers in one of the K.G.L. offices started telling a joke: “What do you call a climate bill that gives Pickens everything he ever dreamed of?” “A Boonedoggle!”

The hardest choices involved the oil industry, which, by powering our transportation, is responsible for almost a third of all carbon emissions in the U.S. Under Waxman-Markey, oil companies would have to buy government permission slips, known as allowances, to cover all the greenhouse gases emitted by cars, trucks, and other vehicles. The oil companies argued that having to buy permits on the carbon market, where the price fluctuated daily, would wreck America’s fragile domestic refining industry. Instead, three major oil refiners—Shell, B.P., and ConocoPhillips—proposed that they pay a fee based on the total number of gallons of gasoline they sold linked to the average price of carbon over the previous three months. The oil companies called the idea “a linked fee.”

On March 23rd, the three senators met to discuss the linked fee, which they had been arguing about for weeks. The environmental community and the White House, which rarely weighed in on its policy preferences, thought the linked fee was disastrous because it would inevitably be labelled a “gas tax.” At one meeting, Joe Aldy, a staffer on Obama’s National Economic Council, advised Kerry, Graham, and Lieberman’s staffers to kill it. According to a person involved in the negotiations, Kerry told his colleagues that the Democrats might lose their congressional majority over the issue. But Lieberman, who had first proposed the linked fee, and Graham supported it.

Kerry, despite his hesitations, wanted the oil companies, which had already spent millions attacking Waxman-Markey, to support his bill. So the senators proposed a deal: the oil companies would get the policy they desired if they agreed to a ceasefire. According to someone present, Kerry told his colleagues at the March meeting, “Shell, B.P., and Conoco are going to need to silence the rest of the industry.” The deal was specific. The ceasefire would last from the day of the bill’s introduction until the E.P.A. released its economic analysis of the legislation, approximately six weeks later. Afterward, the industry could say whatever it wanted. “This was the grand bargain that we struck with the refiners,” one of the people involved said. “We would work with them to engineer this separate mechanism in exchange for the American Petroleum Institute being quiet. They would not run ads, they would not lobby members of Congress, and they would not refer to our bill as a carbon tax.” At another meeting, the three senators and the heads of the three oil companies discussed a phrase they could all use to market the policy: a “fee on polluters.”

On March 31st, Obama announced that large portions of U.S. waters in the Gulf of Mexico, the Arctic Ocean, and off the East Coast—from the mid-Atlantic to central Florida—would be newly available for oil and gas drilling. Two days later, he said, “It turns out, by the way, that oil rigs today generally don’t cause spills. They are technologically very advanced. Even during Katrina, the spills didn’t come from the oil rigs, they came from the refineries onshore.” From the outside, it looked as if the Obama Administration were coördinating closely with Democrats in the Senate. Republicans and the oil industry wanted more domestic drilling, and Obama had just given it to them. He seemed to be delivering on the grand bargain that his aides had talked about at the start of the Administration.

But there had been no communication with the senators actually writing the bill, and they felt betrayed. When Graham’s energy staffer learned of the announcement, the night before, he was “apoplectic,” according to a colleague. The group had dispensed with the idea of drilling in ANWR, but it was prepared to open up vast portions of the Gulf and the East Coast. Obama had now given away what the senators were planning to trade.

This was the third time that the White House had blundered. In February, the President’s budget proposal included $54.5 billion in new nuclear loan guarantees. Graham was also trying to use the promise of more loan guarantees to lure Republicans to the bill, but now the White House had simply handed the money over. Later that month, a group of eight moderate Democrats sent the E.P.A. a letter asking the agency to slow down its plans to regulate carbon, and the agency promised to delay any implementation until 2011. Again, that was a promise Kerry, Graham, and Lieberman wanted to negotiate with their colleagues. Obama had served the dessert before the children even promised to eat their spinach. Graham was the only Republican negotiating on the climate bill, and now he had virtually nothing left to take to his Republican colleagues.

But the Administration had grown wary of cutting the kind of deals that the senators needed to pass cap-and-trade. The long and brutal health-care fight had caused a rift in the White House over legislative strategy. One camp, led by Phil Schiliro, Obama’s top congressional liaison, was composed of former congressional aides who argued that Obama needed to insert himself in the legislative process if he was going to pass the ambitious agenda that he had campaigned on. The other group, led by David Axelrod, believed that being closely associated with the messiness of congressional horse-trading was destroying Obama’s reputation.

“We ran as an outsider and then decided to be an insider to get things done,” a senior White House official said. According to the official, Schiliro and the insiders argued, “You’ve got to own Congress,” while Axelrod and the outsiders argued, “Fuck whatever Congress wants, we’re not for them.” The official added, “We probably did lose part of our brand. Obama turned into exactly what we promised ourselves he wasn’t going to be, which is the leader of parliament. We became the majority leader of both houses, and we ceded the Presidency.” Schiliro’s side won the debate over how the White House should approach health care, but in 2010, when the Senate took up cap-and-trade, Axelrod’s side was ascendant. Emanuel, for example, called Reid’s office in March and suggested that the Senate abandon cap-and-trade in favor of a modest bill that would simply require utilities to generate more electricity from clean sources.

In early April, according to two K.G.L. aides, someone at the Congressional Budget Office told Kerry that its economists, when analyzing the bill, would describe the linked fee as a tax. After learning that, the three senators met with lobbyists for the big oil firms, and Kerry offered a new proposal: the refiners would have to buy permits, but the government would sell them at a stable price outside the regular trading system. This arrangement would make no economic difference to consumers: the oil companies would pass the costs on to drivers whether they paid a linked fee or bought special permits. But Kerry thought that the phraseology could determine whether the bill survived or died. The refiners surprised everyone by readily agreeing to the new terms. The linked fee was dead, and so, it seemed, was the threat of Kerry, Graham, and Lieberman’s bill being brought down by opponents attacking it as a gas tax.

Two days later, on April 15th, Emanuel and Browner hosted a group of prominent environmentalists at the White House for an 11 A.M. meeting. For weeks, the linked fee had been a hot topic among Washington climate-change geeks. Now the two groups that hated the policy the most were in the same room. According to people at the meeting, the White House aides and some of the environmentalists, including Carl Pope, the chairman of the Sierra Club, expressed their contempt for the linked fee: even if it was a fine idea on the merits, it was political poison. The White House aides and the environmentalists either didn’t know that the fee had been dropped from the bill or didn’t think the change was significant. The meeting lasted about thirty minutes.

Just after noon, Rimkunas, Graham’s climate-policy adviser, sent Rosengarten an e-mail. The subject was “Go to Fox website and look at gas tax article asap.” She clicked on Foxnews.com: “WH Opposes Higher Gas Taxes Floated by S.C. GOP Sen. Graham in Emerging Senate Energy Bill.” The White House double-crossed us, she thought. The report, by Major Garrett, then the Fox News White House correspondent, cited “senior administration sources” and said that the “Obama White House opposes a move in the Senate, led by South Carolina Republican Lindsey Graham, to raise federal gasoline taxes within still-developing legislation to reduce green house gas emissions.” Including two updates to his original story, Garrett used the word “tax” thirty-four times.

“This is horrific,” Rosengarten e-mailed Rimkunas.

“It needs to be fixed,” he responded. “Never seen lg this pissed.”

“We’re calling Schiliro and getting the WH to publicly correct.”

Graham was “screaming profanities,” one of the K.G.L. staffers said. In addition to climate change, he was working with Democrats on immigration and on resolving the status of the prison at Guantánamo Bay. He was one of only nine Republicans to vote for Obama’s first Supreme Court nominee, Sonia Sotomayor. Now Obama aides were accusing him of backing a gas tax, which wasn’t his idea and wasn’t even in the draft bill. Worst of all, the leakers went to Fox News, a move which they knew would cause Graham the most damage. He called one of his policy advisers that day and asked, “Did you see what they just did to me?” The adviser said, “It made him question, ‘Do they really want to get this done or are they just posturing here? Because why would they do something like this if they wanted to get it done?’ It was more than an attempt to kill the idea. It was also an attempt to tag him with the idea, and, if you want him to be an ally on the issue, why would you do that?” Graham’s legislative director, Jennifer Olson, argued that he should withdraw from K.G.L. that day.

Kerry called Browner and yelled, “It wasn’t his idea!” He added, “It’s not a gas tax. You’ve got to defend our guy. We’ve been negotiating in good faith, and how can you go and turn on him like this?” After talking to Graham, Lieberman walked into the office of his legislative director, Todd Stein. “If we don’t fix this,” the Senator said, “this could be the death of the bill.”

On April 17th, two days after the Fox story, an activist named William Gheen, speaking at a Tea Party event in Greenville, South Carolina, told the crowd, “I’m a tolerant person. I don’t care about your private life, Lindsey, but as our U.S. senator I need to figure out why you’re trying to sell out your own countrymen, and I need to make sure you being gay isn’t it.” The question, with its false assertion that Graham is gay, turned into a viral video on the Web. Then Newt Gingrich’s group, American Solutions, whose largest donors include coal and electric-utility interests, began targeting Graham with a flurry of online articles about the “Kerry-Graham-Lieberman gas tax bill.” That week, the group launched a campaign in South Carolina urging conservatives to call Graham’s office “and ask him not to introduce new gas taxes.”

Kerry and Lieberman spent hours alone with Graham, trying to placate him. They forced the White House to issue a statement, which said that “the Senators don’t support a gas tax.” Graham had talked to Emanuel and was satisfied that the chief of staff wasn’t the source of the leak. Eventually, the people involved believed that they had mollified him. By the time Graham showed up at the conference table in Emanuel’s White House office on April 20th, he had calmed down. But, if he was going to suffer a ferocious backlash back home, he needed the White House to be as committed as he was. He was not encouraged when Axelrod, speaking about Democrats in Congress, noted, “The horse has been ridden hard this year and just wants to go back to the barn.”

That evening, hours after the meeting ended, a bubble of methane gas blasted out of a well of the Deepwater Horizon oil rig, in the Gulf of Mexico, setting the rig on fire and killing eleven men. At the time, it seemed like a tragic accident, far away and of little consequence.

Kerry and Lieberman were desperate to accommodate Graham’s every request. The dynamics within the group changed. Aides marvelled at how Kerry and Lieberman would walk down the hallway with their arms around each other, while Lieberman and Graham’s relationship was tested by Graham’s escalating demands. The day after the White House meeting, the three senators and their aides gathered to discuss the status of the bill.

After the Fox News leak, a rumor had circulated that Congress wouldn’t pass a highway bill because of the Lindsey Graham gas-tax hike; Graham had to appease truckers in South Carolina. Now he insisted on eight billion dollars for the Highway Trust Fund, saying it was his price for staying. Frangione, Kerry’s aide, was “heartbroken,” a colleague said. It was an enormous amount of money within the confines of the bill, and spending anything on highways increased greenhouse-gas emissions. “Senator, please, just give me five minutes,” Rosengarten told Graham. “I’ll find your eight billion!” She and another Lieberman aide retrieved a spreadsheet they used to track all the spending and revenues in the bill. They fiddled with some numbers and—presto!—Graham had his money. (Later that day, Lieberman figured that, if they were going to spend eight billion dollars on highways, he might as well get some credit, too. He called the American Trucking Association to tell its officials the good news. They responded that they wanted twice that amount.)

Kerry, Lieberman, and their aides needed to keep Graham satisfied for five more days. If they persuaded him to attend the press conference unveiling the bill, he wouldn’t be able to turn back. All the other pieces were falling into place. The legislators met with the Chamber of Commerce to be sure that it would support the bill. Donohue, the Chamber president, said that he wouldn’t stand up with them at the press conference but that the Chamber wouldn’t oppose them, either.

There was just one more deal to make. The Edison Electric Institute represents the biggest electric utilities, and its president, Thomas Kuhn, was another grandee in Republican circles. The E.E.I. already had almost everything it wanted: preëmption, nuclear loan guarantees, an assurance that the cost of carbon would never rise above a certain level, and billions of dollars’ worth of free allowances through 2030 to help smooth the transition into the program. Now the E.E.I. had two new requests: it wanted a billion dollars more in free allowances, and it wanted the start date of the cap-and-trade regime pushed back from 2012 to 2015.

Within minutes, the senators had agreed to almost everything that Kuhn and his lobbyists were asking for. Their three staffers were dumbfounded. The K.G.L. side huddled near a water cooler and the aides staged a mini-rebellion against their bosses. “We were, like, ‘I can’t believe you just gave them all of that! You’ve got to be kidding, this can’t be the deal!’ ” one of them said. “And they were, like, ‘Well, we did it!’ You can’t put that amount of allowances on the table and take it back. You’ve dangled it. The baby’s already eating the candy.” In return for the candy, Kuhn promised that the E.E.I. would provide “a very supportive statement” when the bill was released.

In Lieberman’s office, staffers likened the E.E.I. meeting to the song “Dayenu,” which means “It would have been enough for us,” and is sung at Passover to celebrate the miraculous things God did for the Jews. “If He had brought us out from Egypt, and had not carried out judgments against them—Dayenu! If He had carried out judgments against them, and not against their idols—Dayenu!” Rosengarten imagined an E.E.I.-specific version of the song: “If they had given us the nuclear title, but not the cost collar, Dayenu! If they had given us the cost collar, but not pushed back the start date, Dayenu!” But at least the bill was essentially finished.

What became known as the Dayenu meeting took place on Thursday, April 22nd, Earth Day. A few hours before the meeting, the Deepwater Horizon drilling rig had sunk to the bottom of the Gulf. The spill began to spread; soon it would show signs of becoming one of the worst environmental disasters in history. Then, suddenly, there was a new problem: Harry Reid, the Senate Majority Leader, said that he wanted to pass immigration reform before the climate-change bill. It was a cynical ploy. Everyone in the Senate knew that there was no immigration bill. Reid was in a tough reëlection, and immigration activists, influential in his home state of Nevada, were pressuring him.

Senior aides at the White House were shocked by Reid’s statement. “We were doing well until Reid gave a speech and said it was immigration first. News to us!” a senior Administration official said. “It was kind of like, ‘Whoa, what do we do now? Where did that come from?’ ” Reid’s office seemed to be embarking on a rogue operation. In a three-day period, Reid’s office and unnamed Senate Democrats leaked to Roll Call, The Hill, the Associated Press, Politico, and the Wall Street Journal that the phantom immigration bill would be considered before the climate bill. Graham once again said that he felt betrayed. “This comes out of left field,” he told reporters. “I’m working as earnestly as I can to craft climate and energy independence, clean air and jobs, and now we’re being told that we’re going to immigration. This destroys the ability to do something on energy and climate.”

Graham didn’t tell the press that immigration was mostly just an excuse for his anger. That day, he had urged Reid to release a statement supporting the modified linked fee that Kerry, Graham, and Lieberman had used in negotiating with the refiners. Reid’s office greeted the request with suspicion. Reid and Graham didn’t trust each other. Reid’s aides thought the Republican leadership was trying to trick Reid into supporting something that sounded like a gas tax. The fact that Kerry and Lieberman were also supporters of the proposal did little to allay Reid’s fears. His aides drafted a pro-forma statement for Graham that promised simply that Reid would review the legislation. Graham dismissed the statement as meaningless. During one phone call, Graham shouted some vulgarities at Reid and the line went dead. The Majority Leader had hung up the phone.

At 10 P.M. the next day, Rimkunas sent Rosengarten an e-mail. They had worked together for seven months on the bill. Rosengarten had postponed her honeymoon—twice—to finish the project. They had travelled to Copenhagen together for the international climate conference and often teamed up to oppose Kerry’s office during internal debates. “Sorry buddy” is all the e-mail said. It was devastating. “Matt’s e-mail was a life low point,” she said. “It was actually soul-crushing.”

The next morning, a Saturday, Graham abandoned the talks. Lieberman was observing Shabbat and thus couldn’t work, use electrical devices, or talk on the phone. When his aides explained what was happening, he invoked a Talmudic exception allowing an Orthodox Jew to violate the Shabbat commandments “for the good of the community.” Kerry was in Massachusetts and immediately flew to Washington. The two men spent the morning trying to persuade Graham to stay. At about noon, Graham had a final conversation with Reid, who had nothing more to offer. Graham was out. He wrote a statement, and Olson, his legislative director, e-mailed a copy to Lieberman’s office. The public statement cited immigration as the issue, but attached was a note from Olson explaining that Graham was never going to receive the cover he needed from Reid on how they dealt with the oil refiners.

Rosengarten got the message on her BlackBerry while she was on the phone with Pickens’s policy people, who had no idea about the unfolding drama and wanted to make sure that their natural-gas goodies had survived the final draft of the bill. K.G.L., perhaps the last best chance to deal with global warming in the Obama era, was officially dead. As she read Graham’s definitive goodbye letter, tears streamed down her face.

By the end of April, about sixty thousand barrels of oil a day were flowing into the Gulf of Mexico. To many environmentalists, the Deepwater Horizon catastrophe was a potential turning point, a disaster that might resurrect the climate legislation. But in Washington the oil spill had the opposite effect. Kerry and Lieberman were left sponsoring a bill with a sweeping expansion of offshore drilling at a moment when the newspapers were filled with photographs of birds soaking in oil. Even worse, the lone Republican, who had written the oil-drilling section to appeal to his Republican colleagues, was gone. The White House’s “grand bargain” of oil drilling in exchange for a cap on carbon had backfired spectacularly.

For three months, a period of record-high temperatures in Washington, what was now called the Kerry-Lieberman bill was debated and discussed as if it were a viable piece of legislation, but no Republican stepped forward to support it. During one speech in early June, Obama said that he knew “the votes may not be there right now, but I intend to find them in the coming months.” He never found them, and he didn’t appear to be looking very hard.

Kerry and Lieberman abandoned their attempt to cap the emissions of the oil industry and heavy manufacturers and pared the bill back so that it would cover only the utility industry. The E.E.I. wanted even more if utilities were to be the only guinea pigs for cap-and-trade. This time, the electric companies demanded regulatory relief from non-greenhouse-gas emissions, like mercury and other poisons, as well as more free allowances. Kerry refused to discuss those pollutants, but, in what was probably the nadir of the twenty-month effort, he responded, “Well, what if we gave you more time to comply and decreased the rigor of the reduction targets?” The cap was supposed to be sacrosanct, but Kerry had put it on the table. As a participant said afterward, “The poster child of this bill is its seventeen-per-cent-reduction target. It’s the President’s position in Copenhagen. It’s equal to the House bill.” Now Kerry was saying they could go lower.

As hopes for any kind of bill faded, Kerry and Lieberman kept fighting. They met with Olympia Snowe, who, like Tantalus’ fruit tree, always seemed to be almost within their grasp. She had started talking to them about the utility-only bill, and the two senators begged her to allow them to mention her name publicly to reporters. “Can we please just say that you’re willing to have a conversation about options?” Kerry asked. “No, do not say that,” Snowe responded. Still, Kerry could not resist telling reporters that day, “Even this morning, Senator Lieberman and I had a meeting with one Republican who has indicated a willingness to begin working towards something.”

Meanwhile, there was someone who, like Snowe, was in favor of the bill but was not prepared to do more: Barack Obama. After the K.G.L. failure, environmentalists and congressional aides who work on climate change were critical of the White House. Many of them believe that Obama made an epic blunder by not pursuing climate change first when he was sworn into office. The stimulus failed to reduce unemployment to an acceptable level. The health-care law, while significant, only raised the percentage of people with insurance from eighty-five per cent to ninety-five per cent. Meanwhile, the amount of carbon dioxide in the atmosphere is already above the level that scientists say risks causing runaway global warming. According to the argument, Obama was correct when he said during the campaign that placing a price on carbon in order to transform the economy and begin the process of halting climate change was his more pressing priority.

No diagnosis of the failure of Obama to tackle climate change would be complete without taking into account public opinion. In January, the Pew Research Center asked Americans to rank the importance of twenty-one issues. Climate change came in last. After winning the fight over health care, another issue for which polling showed lukewarm support, Obama moved on to the safer issue of financial regulatory reform.

In September, I asked Al Gore why he thought climate legislation had failed. He cited several reasons, including Republican partisanship, which had prevented moderates from becoming part of the coalition in favor of the bill. The Great Recession made the effort even more difficult, he added. “The forces wedded to the old patterns still have enough influence that they were able to use the fear of the economic downturn as a way of slowing the progress toward this big transition that we have to make.”

A third explanation pinpointed how Kerry, Graham, and Lieberman approached the issue. “The influence of special interests is now at an extremely unhealthy level,” Gore said. “And it’s to the point where it’s virtually impossible for participants in the current political system to enact any significant change without first seeking and gaining permission from the largest commercial interests who are most affected by the proposed change.”

Kerry, Graham, and Lieberman were not alone in their belief that transforming the economy required coöperation, rather than confrontation, with industry. American Presidents who have attempted large-scale economic transformation have always had their efforts tempered—and sometimes neutered—by powerful economic interests. Obama knew that, too, and his Administration had led the effort to find workable compromises in the case of the bank bailouts, health-care legislation, and Wall Street reform. But on climate change Obama grew timid and gave up, leaving the dysfunctional Senate to figure out the issue on its own.

As the Senate debate expired this summer, a longtime environmental lobbyist told me that he believed the “real tragedy” surrounding the issue was that Obama understood it profoundly. “I believe Barack Obama understands that fifty years from now no one’s going to know about health care,” the lobbyist said. “Economic historians will know that we had a recession at this time. Everybody is going to be thinking about whether Barack Obama was the James Buchanan of climate change.” ♦

>In Science We Trust: Poll Results on How You Feel about Science (Scientific American)

>
Our Web survey of readers suggests that the scientifically literate public still trusts its experts—with some important caveats

By The Editors September 22, 2010 11

Scientists have had a rough year. The leaked “Climategate” e-mails painted researchers as censorious. The mild H1N1 flu out­break led to charges that health officials exaggerated the danger to help Big Pharma sell more drugs. And Harvard University in­vestigators found shocking holes in a star professor’s data. As policy decisions on climate, energy, health and technology loom large, it’s important to ask: How badly have recent events shaken people’s faith in science? Does the public still trust scientists?

To find out, Scientific American partnered with our sister publication, Nature, the international journal of science, to poll readers online. More than 21,000 people responded via the Web sites of Nature and of Scientific American and its international editions. As expected, it was a supportive and science-literate crowd—19 percent identified themselves as Ph.Ds. But attitudes differed widely depending on particular issues—climate, evolution, technology—and on whether respondents live in the U.S., Europe or Asia.

How Much Do People Trust What Scientists Say?

We asked respondents to rank how much they trusted various groups of people on a scale of 1 (strongly distrust) to 5 (strongly trust). Scientists came out on top by a healthy margin. When we asked how much people trust what scientists say on a topic-by-topic basis, only three topics (including, surprisingly, evolution) garnered a stronger vote of confidence than scientists did as a whole.

When Science Meets Politics: A Tale of Three Nations

Should scientists get involved in politics? Readers differ widely depending on where they are from. Germany, whose top politician has a doctorate in quantum chemistry, seems to approve of scientists playing a big role in politics. Not so in China. Even though most leaders are engineers, Chinese respondents were much less keen than their German or U.S. counterparts to see scientists in political life.

Build Labs, Not Guns

More than 70 percent of respondents agreed that in tough economic times, science funding should be spared. When asked what should be cut instead, defense spending was the overwhelming pick.

Techno Fears

Technology can lead to unintended consequences. We asked readers what technological efforts need to be reined in—or at least closely monitored. Surprisingly, more respondents were concerned about nuclear power than artificial life, stem cells or genetically modified crops.

U.S. vs. Europe

Europeans and Americans differ sharply in their attitudes toward technology. Higher proportions of respondents from Europe worry about nuclear power and genetically modified crops than those from the U.S. (In this grouping, Europe includes Belgium, France, Germany, Italy and Spain, but not Britain, where opinion is more closely aligned with that of the U.S.) In both Europe and the U.S., nanotechnology seems to be a great unknown. Europeans also expressed a mistrust of what scientists have to say about flu pandemics.


Suspicion Over the Flu

On June 11, 2009, the Geneva-based World Health Organization de­­clared the H1N1 flu outbreak a pandemic, confirming what virologists already knew—that the flu virus had spread throughout the world. Governments called up billions of dollars’ worth of vaccines and antiretroviral drugs, a medical arsenal that stood ready to combat a virus that, thankfully, turned out to be mild.

A year later two European studies charged that the WHO’s decision-making process was tainted by conflicts of interest. In 2004 a WHO committee recommended that governments stockpile antiretroviral drugs in times of pandemic; the scientists on that committee were later found to have ties to drug companies. The WHO has refused to identify the scientists who sat on last year’s committee that recommended the pandemic declaration, leading to suspicions that they might have ties to industry as well.

The controversy got a lot of press in Eu­­rope—­the Daily Mail, a British tabloid, declared: “The pandemic that never was: Drug firms ‘encouraged world health body to exaggerate swine flu threat’”; the controversy in the U.S. garnered little mention.

The brouhaha seems to have influenced opinion markedly in Europe. Nearly 70 percent of U.S. respondents in our survey trusted what scientists say about flu pandemics; in Europe, only 31 percent felt the same way. The figures represented the largest split between the U.S. and Europe on any issue in the poll.

Climate Denial on the Decline

Numerous polls show a decline in the percentage of Americans who believe humans affect climate, but our survey suggests the nation is not among the worst deniers. (Those are France, Japan and Australia.) Attitudes, however, may be shifting the other way. Among those respondents who have changed their opinions in the past year, three times more said they are more certain than less certain that humans are changing the climate.

Sondagem da Nature e Scientific American feita em 18 países, Brasil inclusive, indica que as pessoas acreditam na ciência e nos cientistas

Edição Online – 22/09/2010

Uma tomada de opinião feita pela internet com mais de 21 mil leitores de 18 países, inclusive o Brasil, das revistas Nature e das edições americana e internacionais da Scientific American indica que a credibilidade da ciência e dos cientistas é alta. Feita sem qualquer metodologia científica, como ressaltam seus próprios autores, a enquete divulgada hoje (22/09) mostra que os leitores acreditam mais na palavra dos cientistas do que na de qualquer outro grupo de pessoas.

Numa escala de confiança que variava de zero a cinco, os cientistas receberam a nota média de 3,98, praticamente 4. Em segundo lugar, empatados com a nota 3.09, vieram os grupos de amigos/familiares e as entidades não-governamentais. A seguir apareceram, por ordem decrescente de credibilidade, os grupos de defesa dos cidadãos (2.69), os jornalistas (2.57), as empresas (1.78), os políticos eleitos (1.76) e as autoridades religiosas (1.55). Para realçar a boa avaliação feita do trabalho dos cientistas, a Scientific American usou o título “In Science We Trust“ (“Na Ciência Nós Acreditamos’) em sua reportagem sobre a enquete.

A confiança dos leitores no que os cientistas dizem oscila significativamente de acordo com o tema em questão. Evolução foi o assunto em que a palavra dos pesquisadores recebeu a melhor avaliação no quesito confiabilidade. Obteve a nota 4.3, novamente numa escala que variava de zero a cinco. Também mereceram notas elevadas as opiniões dos cientistas sobre os seguintes temas: energias renováveis (4.08), origem do universo (4) e células-tronco (3.97). Os assuntos em que os leitores menos confiam nos cientistas foram: pandemia de gripe aviária (3.19), drogas para depressão (3.21) e pesticidas (3.33).

A sondagem também mostrou que 89% dos leitores dizem que investir em ciência básica pode não produzir efeitos econômicos imediatos, mas é uma forma de construir as bases para o crescimento futuro. Para 75% dos entrevistados pela enquete, em nome da preservação das verbas para ciência, os governos deveriam cortar os gastos com o setor de armamentos e defesa nacional.

O maior temor tecnológico dos leitores ainda são as usinas atômicas. Quase metade dos entrevistados acredita que formas mais limpas de energia deveriam substituir a nuclear. O segundo tema que mais preocupa as pessoas são possíveis riscos desconhecidos do emprego da nanotecnologia, uma questão citada por 26% dos entrevistados.

Brasil e diferenças regionais – As revistas Nature e Scientific American sabem que a sondagem online não reflete a visão de toda a população dos países em que ela foi realizada. “Muitos dos resultados batem com a opinião de um grupo de pessoas bem informada sobre ciência”, escreveu a Nature. Afinal, 19% das pessoas que participaram da enquete disseram ter o título de doutor. Foi uma elite, portanto, que respondeu a sondagem. Além disso, a amostra de leitores de cada país é desproporcional ao número de habitantes. Do Brasil, por exemplo, participaram 422 pessoas, cerca de 10% do número de norte-americanos.

Ainda assim, algumas diferenças regionais apareceram. Os europeus são os que mais temem os riscos associados ao uso da energia nuclear e possíveis problemas causados pelo cultivo de organismos geneticamente modificados. Já os americanos são os que menos se inquietam com essas questões. Os chineses são os que mais defendem a ideia de que os cientistas não devem se meter em política (os brasileiros foram a segunda nacionalidade que mais apoiou essa posição).

Refletindo a importância que o país ganhou recentemente no cenário internacional, Nature e Scientific American divulgaram alguns dados específicos sobre as respostas dadas pelos brasileiros. Em geral, os brasileiros ocuparam os lugares intermediários nas comparações entre os países. Não são os mais crentes nos cientistas e na ciência, mas também não são os mais descrentes.

No entanto, chamou atenção a quantidade de brasileiros (23.5%) que ainda têm dúvidas sobre as explicações dadas pela teoria evolutiva baseada no processo de seleção natural. Na China a descrença chega a quase metade dos entrevistados e no Japão a 35%. Mas na Alemanha e no Reino Unido o ceticismo sobre esse tema não alcança 10% e nos Estados Unidos está na casa dos 13%. No que diz respeito a admitir que as atividades humanas contribuem para mudar o clima global, os brasileiros foram tão assertivos quanto americanos, ingleses e britânicos: cerca de 80% concordaram com essa afirmação.

>Women more likely than men to accept global warming

Aaron M. McCright, associate professor of sociology
Michigan State University – News

EAST LANSING, Mich. — Women tend to believe the scientific consensus on global warming more than men, according to a study by a Michigan State University researcher.

The findings, published in the September issue of the journal Population and Environment, challenge common perceptions that men are more scientifically literate, said sociologist Aaron M. McCright.

“Men still claim they have a better understanding of global warming than women, even though women’s beliefs align much more closely with the scientific consensus,” said McCright, an associate professor with appointments in MSU’s Department of Sociology, Lyman Briggs College and Environmental Science and Policy Program.

The study is one of the first to focus in-depth on how the genders think about climate change. The findings also reinforce past research that suggests women lack confidence in their science comprehension.

“Here is yet another study finding that women underestimate their scientific knowledge – a troubling pattern that inhibits many young women from pursuing scientific careers,” McCright said.

Understanding how the genders think about the environment is important on several fronts, said McCright, who calls climate change “the most expansive environmental problem facing humanity.”

“Does this mean women are more likely to buy energy-efficient appliances and hybrid vehicles than men?” he said. “Do they vote for different political candidates? Do they talk to their children differently about global warming?”

McCright analyzed eight years of data from Gallup’s annual environment poll that asked fairly basic questions about climate change knowledge and concern. He said the gender divide on concern about climate change was not explained by the roles that men and women perform such as whether they were homemakers, parents or employed full time.

Instead, he said the gender divide likely is explained by “gender socialization.” According to this theory, boys in the United States learn that masculinity emphasizes detachment, control and mastery. A feminine identity, on the other hand, stresses attachment, empathy and care – traits that may make it easier to feel concern about the potential dire consequences of global warming, McCright said.

“Women and men think about climate change differently,” he said. “And when scientists or policymakers are communicating about climate change with the general public, they should consider this rather than treating the public as one big monolithic audience.”

Aqueles que põem em dúvida os efeitos perniciosos da mistura de raça e são levados por falsa filantropia a romper todas as barreiras colocadas entre elas deveriam vir ao Brasil”, afirmou o zoó-logo suíço Louis Agassiz (1807-1873) em seu livro A journey to Brazil (1867), escrito a quatro mãos com a mulher, a americana Elizabeth Cary, resultado da visita ao país como líder da Expedição Thayer, entre 1865 e 1866, da qual fizeram parte, entre outros, o futuro filósofo William James (1842-1910) e o geólogo Charles Frederick Hartt, indo do Rio de Janeiro ao Amazonas. Professor da Lawrence School, ramo da Universidade Harvard, e fundador do Museu de Zoologia Comparada da mesma universidade, Agassiz era o mais notável e popular cientista da América do Norte, defensor do criacionismo, do poligenismo, adepto da teoria da degeneração das raças e um opositor feroz do evolucionismo. Após a publicação de A origem das espécies (1859), de Darwin, porém, seu prestígio passou a ser questionado por jovens naturalistas americanos que rejeitavam suas interpretações teológicas e racistas. Ele então abraçou com entusiasmo a chance de vir ao Brasil com o objetivo de pesquisar os peixes da bacia amazônica para provar a “falácia” das teses darwinistas.

Não menos importante, a viagem era a oportunidade de visitar um “paraíso racialista”. Agassiz aproveitou a sua estada para recolher provas materiais da “degeneração racial” provocada pelo “mulatismo”, comum na população brasileira, fortemente miscigenada. O resultado foi uma série de 200 imagens, conservadas no Museu Peabody de Harvard, em sua maioria inéditas devido ao seu conteúdo polêmico: retratos nus da população africana do Rio e dos tipos mestiços de Manaus. Um grupo de 40 dessas fotografias está sendo exibido pela primeira vez na exposição Rastros e raças de Louis Agassiz: fotografia, corpo e ciência, ontem e hoje, mostra que faz parte da 29ª Bienal de Artes de São Paulo e está em cartaz no Teatro de Arena até o final do mês. Ao mesmo tempo, acaba de ser lançado o catálogo homônimo da exibição, editado por sua curadora, Maria Helena Machado, professora do Departamento de História da Universidade de São Paulo (USP). A pesquisadora também é a organizadora do livro O Brasil no olhar de William James (pela Edusp, a ser lançado até o final do ano), que traz cartas, diários e desenhos do filósofo americano, irmão do escritor Henry James, como integrante da Expedição Thayer. Então um jovem de 23 anos, estudante de medicina em Harvard, James era admirador do suíço, mas a estada brasileira mudou sua visão sobre o “Professor” (como se refere a Agassiz), bem como, nota Maria Helena, foi um ponto decisivo na vida do filósofo do pragmatismo, pois teria sido aqui que ele decidira se dedicar à filosofia. “Indo contra a corrente do momento, seus registros do Brasil são peculiarmente empáticos, apesar de ter contraído varíola, que o deixou temporariamente cego, colidindo com a visão do mentor da viagem, Agassiz, cuja posição política e ideológica o vinculava aos defensores do racismo e das teorias da degeneração pelo hibridismo”, fala a professora.

“Passeando pelo éden amazônico, a Expedição Thayer, com apoio dos governos americano e brasileiro, devassaria a Amazônia, apropriando-se dos peixes, das rochas e capturando imagens dos mestiços e mestiças da região, fotografados nus em poses dúbias, congelados como exemplos da degeneração racial, em nome da construção de um inventário dos perigos da miscigenação”, continua Maria Helena. Agassiz havia se tornado o principal divulgador de uma ciência idealista e cristã, que reafirmava o criacionismo ao mesmo tempo que usava uma linguagem “vanguardista”, cheia de nomes técnicos e alusões a procedimentos científicos. “Se por um lado ele se alinhava no campo dos adeptos da ciência empírica como chave do conhecimento, ao mesmo tempo se reconciliava com as visões metafísicas e religiosas que buscavam interpretar, no livro da natureza, os desígnios divinos.” O zoólogo fora discípulo do naturalista francês Georges Cuvier, que negava a interconexão genética das diferentes espécies, cuja análise pressupunha uma descrição empírica minuciosa dos seres observados, já que cada espécie era única em si mesma. Além disso, Cuvier acreditava que o mundo havia sofrido inúmeras catástrofes que teriam dizimado as espécies que o povoavam, sendo em seguida outras criadas pela mão divina. Assim, os animais que conhecemos teriam sido originados por uma criação recente, hipótese que daria conta do grande problema para os não evolucionistas: a diferença entre os animais fósseis e os atuais.

“Agassiz também preconizava que todos os seres organizados foram criados para pertencer a uma determinada ‘pátria’, ou seja, existiria uma ligação entre os seres e seus hábitats. As diferenças de clima não bastavam para explicar a distribuição das espécies. A lógica do povoamento saíra diretamente de Deus”, explica a historiadora Lorelai Kury, pesquisadora da Fundação Oswaldo Cruz e professora da Universidade do Estado do Rio de Janeiro. Segundo o suíço, existiriam “províncias zoológicas”, já que Deus, depois de ter criado novas espécies em diferentes épocas, teria designado a cada uma a sua “pátria”.

As três poses típicas das fotos de Agassiz.

“O cientista, para Agassiz, era um ser privilegiado que saberia desvendar o plano divino por meio da observação científica da natureza, ocupando o lugar tradicionalmente reservado aos teólogos. Sua visão se ligava a uma perspectiva platônica e estática da vida e da ciência, cujas diretrizes se reportavam a certezas como a existência de tipos ideais e, sobretudo, a reafirmação da precedência do plano divino sobre a realidade do mundo natural”, diz Maria Helena. Ainda segundo o zoólogo, haveria uma hierarquia natural na escala dos seres, de animais para humanos, assim como entre as raças humanas, fruto da intenção divina de impor uma ordem ao mundo. “Cabia aos homens entender e respeitar isso. Os negros, que teriam sido criados por Deus expressamente para habitar os cinturões tropicais, provinham de uma espécie humana inferior, cuja virtude seria a força física e a capacidade de servir. Ante os brancos, superiores, eles abdicavam de sua autonomia em nome da segurança do comando e da proteção de seus mestres. Essas ideias eram comungadas por pró-escravistas e por abolicionistas como Agassiz.” Tal concepção de mundo tinha ampla aceitação, em especial pelo público leigo americano, acalmando suas angústias num mundo em rápida transformação. “Agassiz, durante esse período, estava mais interessado em se dirigir às preocupações do público do que à comunidade científica. Ele ignorava solenemente o número crescente de intelectuais que haviam perdido o interesse na ideia de criações separadas, continuando a dar palestras abertas em defesa do poligenismo e do pluralismo”, observa a antropóloga Gwyniera Isaac, curadora de etnologia americana do Smithsonian’s National Museum of Natural History e autora do artigo “Louis Agassiz’s Photographs in Brazil.”

A viagem ao Brasil era, então, uma necessidade, pois, com a publicidade da expedição, ele acreditava que conseguiria aliados para rebater o evolucionismo e defender a fixidez das espécies e as criações sucessivas. “Na região amazônica, Agassiz dedicou-se a buscar provas de uma recente glaciação que teria marcado uma ruptura entre as espécies atuais e as extintas (o que levou Hartt a se afastar dele), dentro do espírito das catástrofes naturais como responsáveis pela geração de novas espécies, isoladas e sem ligação com outras. Com relação aos peixes, ele acreditava que as espécies encontradas variavam ao longo do Amazonas e eram diferentes para cada afluente”, afirma Lorelai. Contrário a Darwin, Agassiz pensava que a variabilidade em cada espécie era nula e o que hoje se considera uma variedade o zoólogo tomava por uma espécie nova.

O suíço também tinha outros interesses, menos científicos. Desde a sua chegada aos Estados Unidos, em 1840, havia se envolvido no debate norte-americano sobre as raças, abraçando a teoria da degeneração, que afirmava ser a miscigenação ou hibridismo o caminho certo para a degenerescência social. Afinal, se Deus criara a flora, a fauna e o homem em nichos precisos, como o ser humano afrontava esses desígnios misturando climas e raças e, pior, fazendo-as interagir? “Para alguns dos abolicionistas e pensadores racialistas do século XIX, além do mal dos deslocamentos de negros, resultante do tráfico, outro erro, ainda pior, seria o ‘mulatismo’, a conspurcação do sangue ocasionada pela mestiçagem. A solução seria a emigração coletiva ou, pelo menos, a segregação dos afro-americanos em um cinturão de clima quente no Sul, no qual eles viveriam o mais apartado possível, sob a tutela dos brancos”, conta Maria Helena. “Com isso os defensores da incompatibilidade da convivência da raça negra com a civilização acreditavam que os negros seriam impedidos de cometer danos irreparáveis ao corpo da nação.” Em meio à Guerra de Secessão, circulavam, no Norte e no Sul dos Estados Unidos, propostas de “repatriação” dos ex-escravos, inclusive para o Brasil (ver “O dia em que o Brasil disse não aos Estados Unidos”, na edição 156 de Pesquisa FAPESP). Os argumentos de Agassiz sobre as províncias zoológicas, que destinavam as áreas tropicais para a raça negra, tingiam essas propostas com a aura de filantropia. Por isso, observa a pesquisadora, os interesses da Expedição Thayer iam além da ciência. “Por trás do discurso público do cientista-viajante havia outro que ligava Agassiz aos interesses norte-americanos na Amazônia, conectado a duas linhas de ação diplomática: a abertura do Amazonas à navegação internacional e aos projetos de assentamento de negros americanos como colonos ou aprendizes na várzea amazônica, vista como extensão natural do ‘Destino Manifesto’ dos EUA.” O governo norte-americano sabia da ligação entre Agassiz e Dom Pedro II, que trocavam correspondência desde 1863, e o suíço veio ao Brasil para pressionar o imperador a abrir a navegação da Amazônia, no que teve sucesso, e também para ajudar a promover a imigração de negros.

“Nesse sentido, o Brasil era visto como lugar ideal para recolher provas dos perigos da degeneração, que seriam veiculados em sua volta aos EUA. Para isso pensou em fazer uma expressiva coleção de fotografias que documentaria as mazelas da mistura de raças puras e híbridas, tudo com caráter abertamente racialista”, nota Maria Helena. “A consequência natural de alianças entre pessoas de sangue misturado é uma classe de indivíduos em que o tipo puro desaparece assim como todas as qualidades físicas e morais das raças primitivas, produzindo mestiços tão repulsivos como cachorros vira-latas”, anotou Agassiz. Daí a observação precisa de Darwin sobre o rival: “Ele coleta dados para provar uma teoria em vez de observar esses dados para desenvolver uma teoria”. Esse é o princípio que explica as fotografias brasileiras. “Para demonstrar sua tese, ele coletou imagens sobre a classe ‘híbrida’ das populações que, acreditava, eram aparentes no Brasil. Humanos, como qualquer outra espécie, requeriam análise por meio de métodos empíricos e ‘frios’ como a fotografia”, nota Gwyniera Isaac.

Imagens iriam servir de argumento racialista 

Com o objetivo de ilustrar o perfil dos brasileiros, Agassiz encomendou ao fotógrafo profissional Augusto Stahl uma série de daguerreótipos de africanos, que classificou como “tipos raciais puros”, gerando duas séries de fotografias, uma em forma de portraits e outra de caráter científico e fisionômico de tipos étnicos de negros e negras do Rio de Janeiro, incluindo alguns chineses que viviam na cidade. Os retratados aparecem nus e em três posições fixas: de frente, de costas e de perfil. Em Manaus, foi ainda mais longe e criou um Bureau d’Antropologie para documentar as diferenças entre as raças puras e mistas, contando com a ajuda do fotógrafo improvisado Walter Hunnewell na feitura de retratos dos tipos híbridos amazônicos. Agassiz já fizera antes, em 1850, uma série semelhante, com escravos americanos da Carolina do Sul, experiência que, afirma, teria consolidado suas ideias racistas. “Usando novos recursos técnicos, como a fotografia, surgiram teorias sobre as novas formas de capturar o corpo humano, visto como veículo de traços raciais a serem revelados pela capacidade do naturalista de ‘ler corpos’. Ele inaugurou uma representação somatológica e frenológica do outro africano que iria se generalizar nas décadas seguintes e povoaria os nascentes museus antropológicos”, avalia Maria Helena.

“A antropologia havia se transformado, naquela época, na ciência do visível, do corpo físico com suas marcas de distinção racial e, assim, as representações visuais eram cruciais. Nos EUA, isso era obtido por meio da contraposição da cor da pele, o que fazia da raça um conceito baseado no contraste. Ver a imagem de um negro ao lado da de um branco imediatamente provocaria no público a ideia da suposta diferença ‘inerente’ entre as raças. Agassiz, para reforçar isso, interpolou na sua coleção de fotos de negros imagens de estátuas clássicas gregas, versão idealizada dos brancos”, explica a antropóloga Nancy Stepan, da Universidade Columbia, e autora do livro Picturing tropical nature. “A fotografia aparecia como a certeza de verdade para os cientistas, em vez dos antigos desenhos, que seriam limitadores. Foi assim usada na psiquiatria, na medicina, na categorização de criminosos e, no final do século XIX, era uma parte essencial da administração do Estado moderno.”

Agassiz, sem treino nas complicadas mensurações antropométricas, viu na fotografia uma saída, atribuindo à invenção uma “importância de época”. “Ele buscava, porém, o tipo estável que comprovasse a sua noção da fixidez das espécies. Essa procura de um tipo ao qual os indivíduos poderiam teoricamente ser reduzidos, contramão do fluxo contínuo dos seres, cegou Agassiz para a evidência que levou Darwin e Wallace a propor a teoria da evolução. A mesma falácia fez com que suas fotografias, ao final, fossem tão confusas e inesperadas para ele”, afirma a antropóloga. Eram também polêmicas. “Fui para o estabelecimento e lá cautelosamente admitido por Hunnewell com suas mãos negras. Na sala estava o Professor ocupado em persuadir três moças, às quais ele se referia como índias puras, mas, como se confirmou depois, tinham sangue branco. Estavam muito bem vestidas e eram aparentemente refinadas, de qualquer modo não libertinas. Elas consentiram que se tomassem com elas as maiores liberdades e foram induzidas a se despir e posar nuas. Então chegou o sr. Tavares Bastos e me perguntou ironicamente se eu estava vinculado ao Bureau d’Antropologie”, descreveu William James. “Na tradição europeia, da qual Agassiz fazia parte, estar vestido era sinal de civilização e as roupas eram um símbolo de status e gênero. Deixar pessoas nuas roubava delas a dignidade e a humanidade. Para ele, isso era possível porque muitas eram escravas”, observa Nancy.

“Muitas das mulheres fotografadas, porém, eram da boa sociedade de Manaus e o clima no Bureau não era dos mais respeitosos. As fotos se situam numa zona desconfortável entre o científico e o erótico, gêneros que se cruzavam com frequência no século XIX. As observações de James revelam o clima de segredo, o que contrasta com as afirmações de Agassiz sobre a natureza abertamente científica das fotos. Além disso, a menção de James sobre as ‘mãos negras’ de Hunnewell tem um duplo sentido que vai além da sujeira dos produtos químicos”, analisa o antropólogo John Monteiro, da Universidade Estadual de Campinas. Ao mesmo tempo as fotos se enquadravam na convenção etnográfica de introduzir o confortável espectador branco àquilo que é não apenas exótico, e está em distância segura, como também invisível. O resultado das imagens coletadas, porém, não era o esperado por Agassiz. “O livro do casal e os diários de James estão cheios de exemplos frustrados de encontrar tipos ‘puros’. O Brasil conseguiu confundir Agassiz, que acreditava estar num país com exemplos definidos das três raças ‘puras’. Ele se deparou, porém, com ‘hí­bridos’ que cruzaram com outros ‘híbri­dos’ e assim por diante, gerando uma realidade complexa que não poderia ser apreendida em suas fotografias”, diz Nancy. “Isso era impossível sem lançar mão de outros recursos, como legendas, o que ia de encontro ao seu método científico em que as ‘raças falavam por si mesmas’. Paradoxalmente, ao despir seus modelos, Agassiz removeu alguns dos poucos signos que poderia ter usado para assegurar as identidades raciais dos tipos.”

A coleção brasileira nunca foi divulgada e em A journey to Brazil aparecem apenas algumas delas como base para xilogravuras. “Para isso contribuiu uma série de razões políticas e acadêmicas que acabaram por inviabilizar o seu projeto de estudo das raças. Há que se considerar também o ambiente moral rígido da Nova Inglaterra e a perda da credibilidade científica de Agassiz. As fotos guardam, no entanto, uma atua­lidade, ao evocar os rostos e vidas de pes­soas que foram anuladas não apenas pela ‘objetificação’ da ciência, mas pelas políticas de esquecimento”, diz Maria Helena. William James resume bem a questão: “Tenho me beneficiado em ouvir Agassiz falar, não tanto pelo que ele diz, pois nunca ouvi ninguém pôr para fora uma quantidade maior de bobagens, mas por aprender a forma de funcionar desta vasta e prática máquina que ele é”.

The anti-science strain pervading the right wing in the United States is the last thing the country needs in a time of economic challenge.

“The four corners of deceit: government, academia, science and media. Those institutions are now corrupt and exist by virtue of deceit. That’s how they promulgate themselves; it is how they prosper.” It is tempting to laugh off this and other rhetoric broadcast by Rush Limbaugh, a conservative US radio host, but Limbaugh and similar voices are no laughing matter.

There is a growing anti-science streak on the American right that could have tangible societal and political impacts on many fronts — including regulation of environmental and other issues and stem-cell research. Take the surprise ousting last week of Lisa Murkowski, the incumbent Republican senator for Alaska, by political unknown Joe Miller in the Republican primary for the 2 November midterm congressional elections. Miller, who is backed by the conservative ‘Tea Party movement’, called his opponent’s acknowledgement of the reality of global warming “exhibit ‘A’ for why she needs to go”.

“The country’s future crucially depends on education, science and technology.”

The right-wing populism that is flourishing in the current climate of economic insecurity echoes many traditional conservative themes, such as opposition to taxes, regulation and immigration. But the Tea Party and its cheerleaders, who include Limbaugh, Fox News television host Glenn Beck and Sarah Palin (who famously decried fruitfly research as a waste of public money), are also tapping an age-old US political impulse — a suspicion of elites and expertise.

Denialism over global warming has become a scientific cause célèbre within the movement. Limbaugh, for instance, who has told his listeners that “science has become a home for displaced socialists and communists”, has called climate-change science “the biggest scam in the history of the world”. The Tea Party’s leanings encompass religious opposition to Darwinian evolution and to stem-cell and embryo research — which Beck has equated with eugenics. The movement is also averse to science-based regulation, which it sees as an excuse for intrusive government. Under the administration of George W. Bush, science in policy had already taken knocks from both neglect and ideology. Yet President Barack Obama’s promise to “restore science to its rightful place” seems to have linked science to liberal politics, making it even more of a target of the right.

US citizens face economic problems that are all too real, and the country’s future crucially depends on education, science and technology as it faces increasing competition from China and other emerging science powers. Last month’s recall of hundreds of millions of US eggs because of the risk of salmonella poisoning, and the Deepwater Horizon oil spill, are timely reminders of why the US government needs to serve the people better by developing and enforcing improved science-based regulations. Yet the public often buys into anti-science, anti-regulation agendas that are orchestrated by business interests and their sponsored think tanks and front groups.

In the current poisoned political atmosphere, the defenders of science have few easy remedies. Reassuringly, polls continue to show that the overwhelming majority of the US public sees science as a force for good, and the anti-science rumblings may be ephemeral. As educators, scientists should redouble their efforts to promote rationalism, scholarship and critical thought among the young, and engage with both the media and politicians to help illuminate the pressing science-based issues of our time.
