零排放任务

达沃斯—地球警报在拉响。政府间气候变化委员会(Intergovernmental Panel on Climate Change)2013年报告明确指出,最有可能的罪魁祸首是我们在过去半个世纪中所排放的二氧化碳。我们需要更更鲁棒的全球变暖应对方针才能避免灾难。与最近的金融危机不同,地球气候可没有援助选项可选。

三年前,在坎昆联合国COP 16气候变化上,各国同意在2020年把排放量降低到足以阻止全球平均气温比工业化之前高2℃的水平。但是,联合国的估计表明,当前趋势只能让世界完成这一目标的25—50%。

这就是我呼吁所有政府都应该提高决心、以到本世纪下半叶实现化石燃料零净排放为目标的原因。没有能源经济的全面变化,这一目标就不可能实现。

    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.
