“It is naive to think that the work of climatologists will trigger the necessary political decisions”

Phy are governments reacting so little when the scientific evidence of the existence of a major dysfunction in the Earth system is accumulating? On May 31, the review Nature To published the results of a study (“ A just world on a safe planet: First study quantifying Earth System Boundaries »Potsdam Institute for Climate Impact Research, PIK) drawn up by an international scientific commission, bringing together more than forty researchers from all over the world, which warned in very worrying terms: “Man is taking colossal risks for the future of civilization and all that lives on Earth. »

Resistance to science, less frontal and more subtle

Should resistance to science be blamed? Climatoscepticism is far from having disappeared, in our country as elsewhere. We still find – admittedly more discreetly than before but in an equally assertive manner – public expressions defending the following ideas: the current warming is a natural phenomenon that has nothing to do with human activity; the assertions of the Intergovernmental Panel on Climate Change (IPCC) are lies stemming from the manipulations of the American Democrats; the policies resulting from the work of the IPCC would be dramatic because they would destroy our industries and our jobs. Few governments, however, venture to officially adopt these claims.

There are, however, other forms of resistance to science, less frontal and more subtle, to which governments can lend a more attentive ear and which scientists themselves can nurture.

One thinks here of the strategies of lobbyists unveiled by Naomi Oreskes and Erik Conway in The Merchants of Doubt (Le Pommier, 2012) and by social science works devoted to agnotology, i.e. the way in which ignorance can be produced for the purpose of manipulation (see for example The Guardians of ReasonStéphane Foucart, Stéphane Horel, Sylvain Laurens, La Découverte, 2020).
