G-7重视去碳化

纽约—本周的巴伐利亚阿尔卑斯山脉艾尔毛城堡(Schloss Elmau)的G-7会议标志着气候变化政策的重大突破。七大高收入经济体(美国、日本、德国、英国、法国、意大利和加拿大)做出了革命性决定——要在本世纪实现经济的去碳化。

历史上第一次,主要发达经济体认可了摆脱化石燃料依赖的需要。德国总理默克尔、美国总统奥巴马和其他G-7领导人做出了这样的决定,值得全球人民赞赏。

这一历史性突破记录在最终的G-7通报中。首先,G-7国家强调了将全球变暖幅度控制在2℃以下的重要性。这意味着地球平均气温将不会超过工业革命(略早于1800年)前平均气温以上2℃。但截至今日全球变暖幅度已经达到了0.9℃左右——也就是增温上限的一半。

    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 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.
