It would be nice to claim that the explosion of interest was due to the film itself, but the fuss started even before the film was broadcast. The reason, we suspect, is that the coverage of ‘global warming’, on TV, radio and in the press, has been so one-sided and uncritical. In Britain, hours and hours of programmes have been broadcast by the BBC on the subject, much of it scientifically absurd. The very fact that a science documentary dared to challenge the orthodoxy was itself news.
Why? Why have journalists been so craven or biased? How has a theory which demonstrably lacks really solid supporting evidence become an indisputable fact? What of the impressive, much talked about scientific ‘consensus’ which is used to forestall any awkward questions about the evidence?
Science and scientists cannot always rise above the prejudices of their class and of their age. The selection and handling of evidence often reflects these prejudices. The most highly qualified and respected scientists can be blind to obvious deficiencies in a theory, and will be dismissive of evidence when it undermines what they want to believe.
