Writes Terence Corcoran in Canada’s Financial Post:

It is now firmly established, repeated ad nauseam in the media and elsewhere, that the debate over global warming has been settled by scientific consensus. The subject is closed. It seems unnecessary to labour the point, but here are a couple of typical statements: “The scientific consensus is clear: human-caused climate change is happening” (David Suzuki Foundation); “There is overwhelming scientific consensus” that greenhouse gases emitted by man cause global temperatures to rise (Mother Jones).

[…] Global warming science by consensus, with appeals to United Nations panels and other agencies as authorities, is the apotheosis of the century-long crusade to overthrow the foundations of modern science and replace them with collectivist social theories of science. “Where a specific body of knowledge is recognized and accepted by a body of scientists, there would seem to be a need to regard that acceptance as a matter of contingent fact,” writes Barnes. This means that knowledge is “undetermined by experience.” It takes us “away from an individualistic rationalist account of evaluation towards a collectivist conventionalist account.”

In short, under the new authoritarian science based on consensus, science doesn’t matter much any more. If one scientist’s 1,000-year chart showing rising global temperatures is based on bad data, it doesn’t matter because we still otherwise have a consensus. If a polar bear expert says polar bears appear to be thriving, thus disproving a popular climate theory, the expert and his numbers are dismissed as being outside the consensus. If studies show solar fluctuations rather than carbon emissions may be causing climate change, these are damned as relics of the old scientific method. If ice caps are not all melting, with some even getting larger, the evidence is ridiculed and condemned. We have a consensus, and this contradictory science is just noise from the skeptical fringe.
