||I am not arguing that global warming is the same as eugenics. But the similarities are not superficial. And I do claim that open and frank discussion of the data, and of the issues, is being suppressed. Leading scientific journals have taken strong editorial positions of the side of global warming, which, I argue, they have no business doing. Under the circumstances, any scientist who has doubts understands clearly that they will be wise to mute their expression. One proof of this suppression is the fact that so many of the outspoken critics of global warming are retired professors. These individuals are not longer seeking grants, and no longer have to face colleagues whose grant applications and career advancement may be jeopardized by their criticisms.
