Oriundos de mais de uma dúzia de países, mais de uma centena de proeminentes cientistas – incluindo um laureado com um prémio Nobel – assinaram uma carta dirigida ao Presidente Obama classificando como “simplesmente incorrectas” as posições de Obama acerca das alterações climáticas.Esta carta – patrocinada pelo Cato Institute – contesta a seguinte declaração de Obama, proferida em 19 de Novembro de 2008 : “Poucos desafios enfrentados pela América e pelo mundo exigem um combate mais urgente do que as alterações climáticas. As conclusões científicas são inquestionáveis e os factos são claros”.Sob o título “Com o devido respeito, Senhor Presidente, isso não é verdade”, os mais de cem cientistas declararam o seguinte :Os abaixo assinados defendem que os receios em torno das alterações climáticas estão grosseiramente sobrestimados. Ao longo do século passado as variações da temperatura à superfície do planeta foram episódicas e modestas e, além disso, não tem havido qualquer aquecimento global desde há uma década.Os modelos de computador que prevêem um aumento rápido da temperatura falham de uma forma inaudita na explicação da recente evolução climática.Senhor Presidente : a sua caracterização dos factos científicos relacionados com as alterações climáticas e o grau de certeza que supõe incorporado no debate científico está pura e simplesmente incorrecto.Os 116 signatários incluem : Ivar Giaever, Ph.D., que partilhou o Prémio Nobel da Física de 1973 pelo seu trabalho em supercondutores na General Electric ; John Blaylock, anteriormente no Laboratório Nacional de Los Alamos ; Richard Lindzen, Ph.D., do Instituto Tecnológico de Massachusetts; e William Gray, Ph.D., um respeitado perito de furacões da Universidade do Estado do Colorado.Os subscritores incluem ainda cientistas da Universidade de Princeton, da Academia Naval dos Estados Unidos, da Universidade do Kansas, da Universidade de Oklahoma, da Universidade do Colorado e da Universidade do Missouri.Entre os países representados pelos subscritores estão a Grã-Bretanha, Canadá, Itália, Noruega, Alemanha, Austrália, Nova Zelândia, Japão, Argentina e África do Sul.Alguns dos cientistas são actuais ou anteriores recensores do Painel Intergovernamental para as Alterações Climáticas – os quais partilharam o Prémio Nobel da Paz de 2007 com Al Gore, o militante do aquecimento global – e que, desde então, inverteram as suas posições acerca do aquecimento global com origem antropogénica.
