Here is a brief summary of the paper the FSM has published:
All public policies, in France, Europe and throughout the world, find their origin and inspiration in the battle against global warming.
The impact on the entire field of scientific research is particularly clear and especially pernicious. No project can be launched, on any subject whatsoever, unless it makes direct reference to global warming. You want to look at the geology of the Garonne Basin? It is, after all, an entirely normal and socially useful subject in every respect. Well, your research will be funded, approved and published only if it mentions the potential for geological storage of CO2. It is appalling.
The crusade has invaded every area of activity and everyone‘s thinking: the battle against CO2 has become a national priority. How have we reached this point, in a country that claims to be rational?
At the root lie the declarations made by the IPPC, which have been repeated over the years and taken up by the European Commission and the Member States. France, which likes to see itself as the good boy of Europe‘, adds an extra layer of virtue to every crusade. When others introduce reductions, we will on principle introduce bigger reductions, without ever questioning their appropriateness: a crusade is virtuous by its very nature. And you can never be too virtuous.
But mathematicians do not believe in crusades; they look at facts, figures, observations and arguments.
