De l’importance de l’adaptation au réchauffement climatique

COPENHAGEN – Le bon dosage entre l’endiguement du réchauffement et les processus d’adaptation à ses effets est l’un des enjeux politiques les plus importants – et les plus ardus – de notre époque. On le passe très souvent sous silence.

Les écologistes sont généralement d’avis de faire tout notre possible pour atténuer le réchauffement dans un premier temps, et de définir des stratégies d’adaptation dans un deuxième temps. Mais comme un effort d’adaptation nous permettra de faire davantage pour les gens et pour la planète, il apparaît que ce point de vue est erroné – immoral, même.

Ce point de vue est en outre incompatible avec l’incontournable fait que, quoi que l’on fasse, on ne pourra  pas éviter tous les effets du réchauffement. Moins nous y serons préparés et plus le réchauffement fera de morts et de ravages, surtout dans les pays pauvres et les sociétés fragiles. S’adapter signifie également éviter à beaucoup de périr de catastrophes dont le réchauffement n’est pas responsable. En amenant les sociétés à se préparer aux destructions de futurs ouragans, par exemple, nous serons plus à même de les aider à faire face aux extrémités climatiques d’aujourd’hui.

    Populist Plutocracy and the Future of America

    • In the first year of his presidency, Donald Trump has consistently sold out the blue-collar, socially conservative whites who brought him to power, while pursuing policies to enrich his fellow plutocrats. 

    • Sooner or later, Trump's core supporters will wake up to this fact, so it is worth asking how far he might go to keep them on his side.

    The Man Who Didn’t Save the World

    A Saudi prince has been revealed to be the buyer of Leonardo da Vinci's "Salvator Mundi," for which he spent $450.3 million. Had he given the money to the poor, as the subject of the painting instructed another rich man, he could have restored eyesight to nine million people, or enabled 13 million families to grow 50% more food.

    Two Myths About Automation

    While many people believe that technological progress and job destruction are accelerating dramatically, there is no evidence of either trend. In reality, total factor productivity, the best summary measure of the pace of technical change, has been stagnating since 2005 in the US and across the advanced-country world.

    The Hungarian Government’s Failed Campaign of Lies

    The Hungarian government has released the results of its "national consultation" on what it calls the "Soros Plan" to flood the country with Muslim migrants and refugees. But no such plan exists, only a taxpayer-funded propaganda campaign to help a corrupt administration deflect attention from its failure to fulfill Hungarians’ aspirations.
