Les pollueurs doivent payer

J'écris ces lignes à New-York au début du mois d'août. Le maire vient de décréter une "alerte à la canicule" pour éviter une panne d'électricité à grande échelle, car on s'attend à une augmentation importante de l'utilisation de l'air conditionné. Les employés municipaux peuvent être poursuivis devant la justice s'ils règlent leur thermostat en dessous de 25,5°. Néanmoins, l'utilisation de l'électricité touche des pics rarement atteints.

Au même moment, la Californie sort d'une canicule record. Aux USA, les six premiers mois de 2006 ont été les plus chauds depuis plus d'un siècle. En Europe, l'été est aussi exceptionnellement chaud. L'Angleterre et les Pays-Bas, où l'on enregistre les températures les plus élevées depuis plus de trois siècles, ont également battu des records de chaleur en juillet.

La canicule de cet été dans l'hémisphère nord tombe à pic avec la sortie du documentaire intitulé An Inconvenient Truth, un film remarquable dans lequel apparaît l'ancien vice-président américain Al-Gore. Au moyen de graphiques, d'images et encore d'autres éléments, le film prouve que les émissions de gaz carbonique sont à l'origine du réchauffement planétaire, ou tout au moins y contribuent, et qu'il faut d'urgence trouver une solution.

    The Brexit Surrender

    European Union leaders meeting in Brussels have given the go-ahead to talks with Britain on post-Brexit trade relations. But, as European Council President Donald Tusk has said, the most difficult challenge – forging a workable deal that secures broad political support on both sides – still lies ahead.

    • Congressional Republicans are finalizing a tax-reform package that will reshape the business environment by lowering the corporate-tax rate and overhauling deductions. 

    • But will the plan's far-reaching changes provide the boost to investment and growth that its backers promise?

  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.
