On issues ranging from genetically modified crops to nuclear power, environmentalists are increasingly refusing to listen to scientific arguments that challenge standard green positions. This approach risks weakening the environmental movement and empowering climate contrarians.
(…) And yet, recently, the environment movement seems to have been turning up on the wrong side of the scientific argument. We have been making claims that simply do not stand up. We are accused of being anti-science — and not without reason. A few, even close friends, have begun to compare this casual contempt for science with the tactics of climate contrarians.
That should hurt.
Three current issues suggest that the risks of myopic adherence to ideology over rational debate are real: genetically modified (GM) crops, nuclear power, and shale gas development. The conventional green position is that we should be opposed to all three. Yet the voices of those with genuine environmental credentials, but who take a different view, are being drowned out by sometimes abusive and irrational argument.
