Sério Gui? Que tudo! Parabéns as duas!

Ontem li um cara questionando a histeria do Aquecimento Global e dizendo que ele também ocorre em Marte. Isso seria uma prova que o homem não é o responsável, né? (nem a mulher, nem gente intersexuada, etc)

Está passando uma série que parece ser interessante no Fantástico, prometendo falar mais da ação humana como causa nos próximos programas.

Ainda não li o que postou, mas acho que o cara faria melhor talvez em citar Vênus, que é bem mais quente que Marte.

Que eu saiba, não há dúvidas de que ocorram variações climáticas naturais, mas também não dá para descontar influência da ação humana, segundo o consenso no mainstream científico. Ou seja, mesmo que estivéssemos ou estejamos num período de aquecimento natural, ainda assim a nossa ação teria alguma relevância.

How ‘Balanced’ Coverage Lets the Scientific Fringe Hijack Reality


[...]

Journalists face a number of pressures that can prevent them from accurately depicting competing scientific claims in terms of their credibility within the scientific community as a whole. First, reporters must often deal with editors who reflexively cry out for “balance.” Meanwhile, determining how much weight to give different sides in a scientific debate requires considerable expertise on the issue at hand. Few journalists have real scientific knowledge, and even beat reporters who know a great deal about certain scientific issues may know little about other ones they’re suddenly asked to cover.

No wonder scientists have often denounced the press for giving credibility to fringe scientific viewpoints. And without a doubt, the topic on which scientists have most vehemently decried both the media and the Bush administration is global warming. While some scientific uncertainty remains in the climate field, the most rigorous peer-reviewed assessments — produced roughly every five years by the United Nations’ Intergovernmental Panel on Climate Change (IPCC) — have cemented a consensus view that human greenhouse gas emissions are probably (i.e., the conclusion has a fairly high degree of scientific certainty) helping to fuel the greenhouse effect and explain the observed planetary warming of the past fifty years. Yet the Bush administration has consistently sought to undermine this position by hyping lingering uncertainties and seeking to revise government scientific reports. It has also relied upon energy interests and a small cadre of dissenting scientists (some of whom are funded, in part, by industry) in formulating climate policy.

Academics have studied media coverage of climate change, and the results confirm climate scientists’ longstanding complaints. In a recent paper published in the journal Global Environmental Change, the scholars Maxwell T. Boykoff and Jules M. Boykoff analyzed coverage of the issue in The New York Times, The Washington Post, The Wall Street Journal, and the Los Angeles Times between 1988 and 2002. During this fourteen-year period, climate scientists successfully forged a powerful consensus on human-caused climate change. But reporting in these four major papers did not at all reflect this consensus.
