Un prix Nobel de la paix qui dérange

Le prix Nobel de la paix de cette année récompense à juste titre les milliers de scientifiques du panel de l’ONU sur le climat, le Groupe intergouvernemental d'experts sur l'évolution du climat (Giec). Ces scientifiques ont effectué un travail minutieux et de haute qualité, qui définit exactement ce à quoi nous devons nous attendre en raison du réchauffement climatique.

L’autre récipiendaire du prix, l’ancien vice-président américain Al Gore, a consacré davantage de temps à nous dire de quoi il fallait avoir peur. Alors que les estimations et conclusions du Giec sont fondées sur des études précises, Gore ne semble pas avoir fait preuve de la même retenue.

Dans son film récompensé par deux Oscars (et récemment critiqué par un juge britannique pour sa propagande politique et ses inexactitudes scientifiques), Gore prévoit une augmentation du niveau de la mer de 6 mètres au cours du siècle. Il ne tient pas compte des données des co-lauréats du Giec, qui estiment que cette augmentation se situera entre 15 et 60 centimètres, et le plus probablement à 30 centimètres. Cette hausse équivaut à celle constatée au cours des derniers 150 ans.

    The Brexit Surrender

    European Union leaders meeting in Brussels have given the go-ahead to talks with Britain on post-Brexit trade relations.

  3. Murdoch's Last Stand?

    Rupert Murdoch’s sale of 21st Century Fox’s entertainment assets to Disney for $66 billion may mark the end of the media mogul’s career, which will long be remembered for its corrosive effect on democratic discourse on both sides of the Atlantic. 

    From enabling the rise of Donald Trump to hacking the telephone of a murdered British schoolgirl, Murdoch’s media empire has staked its success on stoking populist rage.

    The Dangerous Delusion of Price Stability

    Since the hyperinflation of the 1970s, which central banks were right to combat by whatever means necessary, maintaining positive but low inflation has become a monetary-policy obsession. But, because the world economy has changed dramatically since then, central bankers have started to miss the monetary-policy forest for the trees.

  5. Harvard’s Jeffrey Frankel Measures the GOP’s Tax Plan

    Jeffrey Frankel, a professor at Harvard University’s Kennedy School of Government and a former member of President Bill Clinton’s Council of Economic Advisers, outlines the five criteria he uses to judge the efficacy of tax reform efforts. And in his view, the US Republicans’ most recent offering fails miserably.

    The Holy Grail of Genetic Engineering

    CRISPR-Cas – a gene-editing technique that is far more precise and efficient than any that has come before it – is poised to change the world. But ensuring that those changes are positive – helping to fight tumors and mosquito-borne illnesses, for example – will require scientists to apply the utmost caution.
