Not All Scientific Consensuses are Equal

Ronald Bailey, writing in Reason magazine, notes an interesting disconnect in Green thought.

[W]hen it comes to climate change, environmentalists righteously wrap themselves in the cloak of scientific "consensus." They excoriate scientists and others who doubt that man-made climate change will necessarily be disastrous, accusing some of being essentially paid liars for the fossil fuel industry. But for many environmentalist groups not all scientific consensuses are equal. Consider the case of genetically enhanced crops.

...

[T]he overwhelming scientific consensus is that current varieties of genetically enhanced crops are safe to eat and don't pose unusual risks to the natural environment. But that isn't stopping Greenpeace from waging a global "Say no to genetic engineering" campaign or the Friends of the Earth from demanding a GM freeze. Perhaps the idea of scientific consensus is not all that it's cracked up to be. After all, scientific consensus does not mean "certain truth." Whatever the current consensus of any scientific issue is can change in the light of new research. Nevertheless, environmentalist ideologues accuse those who question the climate change consensus of bad faith and worse. But aren't they exhibiting a similar bad faith when they reject the broad scientific consensus on genetically modified crops?

Of course to the luddites, science is only a tool of convenience to be wielded when useful and ignored when it does not support their goals.
