Merchants of doubt

Ever since researchers first began examining the evidence that our planet was heating up — and that human activities were probably to blame, people have been questioning the data, doubting the evidence, and attacking the scientists who collect and explain it. Science historian Naomi Oreskes gives a US perspective on how a cadre of ideologues have clouded the public interpretation of scientific facts to advance a political and economic agenda. Campaigns to mislead the public and deny well-established scientific knowledge over four decades include denying the links between smoking and lung cancer, CFC’s and the ozone hole, and coal smoke and acid rain.
