Notre dernière chance pour une planète sûre

MELBOURNE – L’humanité a peut-être trop tardé à réagir au changement climatique. Les chercheurs scientifiques ont bien indiqué qu’une augmentation des températures de 2º Celsius par rapport aux niveaux préindustriels placerait la Terre dans une dangereuse posture, en territoire inconnu. Il est pourtant question aujourd’hui d’une augmentation des températures d’au moins 4º au cours de ce siècle. Il nous reste une dernière chance pour agir.

Cette chance repose sur Paris, où les chefs de gouvernements de la planète se réuniront en décembre 2015 pour le 21ème sommet de l’ONU sur le changement climatique. Mais ce sera différent cette fois. Soit les gouvernements conviendront d’une action décisive, comme ils l’ont promis, soit nous nous souviendrons de 2015 comme l’année ou nous aurons laissé échapper notre bons sens climatique.

En 1992, les gouvernements du monde avaient adopté la Convention cadre de l’ONU sur le changement climatique, promettant d’éviter « toute interférence anthropogénique (induite par l’homme) dans le système climatique en limitant le taux d’émissions de gaz à effet de serre, surtout de dioxyde de carbone. Mais, malgré l’entrée en vigueur du traité en 1994, le taux des émissions de gaz à effet de serre, y compris celui du CO2, a effectivement augmenté.

    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.
