The most telling feature of the climate-sceptic movement (aside from the large amount of money behind it) is that it is organized along the left–right political axis, with the left generally being sympathetic to climate science and the right far less so.

Liberals usually view science as a force for change that could benefit society. For conservatives, science typically serves to reinforce the status quo by making society more efficient and more powerful. This is not to brand the right as anti-science (see Nature 468, 508; 2010): as an objective truth, science is an appealing bulwark against the relativism of liberals.

Scepticism about global warming illustrates the right's difficulty in conceptualizing the group (rather than the individual) as a political actor. Conservatives traditionally believe that the course of history is decided by a few heroic figures — Churchill, Napoleon, and so on. The left tends to sideline such figures in favour of the mass movements they spearheaded. The right's popular argument that global warming is a hoax neatly demonstrates this. After all, a hoax demands a hoaxer, a 'heroic villain' who is faking data and distributing bribes behind the scenes.

If one believes in mass movements, it is easy to imagine a mass movement of waste — a kind of rotten plebiscite cast against our planet. If one does not, global warming cannot help but seem unlikely, no matter how strong the evidence.
