L'aveuglement volontaire face au réchauffement planétaire

Le traité de Kyoto sur le contrôle des changements climatiques a été, comme le dit Rob Stavins, enseignant à Harvard, “trop insuffisant, trop expéditif.” D'une part, étant donné qu'il ne concerne que les pays supposés émettre environ la moitié des gaz à effet de serre du monde d'ici 2050, il ne constitue pas un garde-fou efficace sur le long terme contre les dangers du réchauffement climatique. D'autre part, comme il demande aux pays industrialisés des réductions d'émissions significatives et coûteuses, il menace de coûter sur le champ très cher aux économies américaine, européenne et japonaise. En bref, l'accord de Kyoto promet beaucoup de souffrance à court terme pour peu de gains à long terme.

L'Union européenne et les économistes des États-unis du temps de l'administration Clinton ont défendu l'adoption du traité de Kyoto pour finir par donner l'exemple d'un système qui n'est pas le traité de Kyoto. Ils ont programmé l'intégration des pays en développement dans le cadre du protocole, et l'échange avec les États-Unis et l'Europe du droit de ces pays à émettre du CO2 et autres gaz à effet de serre contre des aides au développement.

Pourtant, après toutes ces années, je n'ai encore rencontré personne qui sache vraiment de quoi il parle et soit prêt à défendre l'accord de Kyoto en tant que véritable politique publique mondiale. “C'était un moyen de lancer le débat” sur les changements climatiques assurent certains. “C'était une façon de faire prendre conscience au monde de la gravité du problème,” disent les autres.

    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.
