Comment se construit la confiance dans les sciences et les politiques du climat? Retour sur un colloque international

Abstract

Taking as a starting point the communications at an international conference held in Paris in 2014, the article analyzes the construction of confidence in climate sciences and politics. How, by which methods and procedures, do climate modeling communities establish the validity of their models? What link can be established between the confidence in numerical simulations of global warming and in the capacity of the international system to successfully tackle the climate issue? The article shows that the existence of a close link between these different forms of confidence questions common belief that expertise should be completely separated from the political process. More generally, it examines the necessity of a "constitution" for the science-policy relationship at the global level at a time where new paradigms for research and for policy converge toward increasing importance of regional and local levels.
