改变气候变化

记载中最温暖的十年都出现在1990年以后,而2005年很可能成为最暖的一年。今年,我们初尝了未来将会面对的许多危险的况味:更为极端的飓风、大面积的干旱、森林火灾、传染病的蔓延和洪水。气候正在变化,而更多的变化即将发生。

世界各国的政府将在11月底汇集蒙特利尔,制定下一步的应对方案。其中包括在布什政府放弃有意忽视该问题的态度之后,世界各国可能采取的具体步骤。

气候变化被等同于“全球变暖”,但其实质内容要比变暖多得多。二氧化碳等温室气体的浓度越来越高,正导致着更为极端的风暴、更高强度的飓风、海平面上升、冰川和冰盖融化、干旱、洪灾和其他气候变化。甚至连土地和海洋的化学成分也发生着变化。海水的酸性日益增强—进而威胁着珊瑚礁—就是二氧化碳含量增加的结果。

    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.
