让北京呼吸得更轻松

近几个星期以来,北京似乎沐浴在烟雾笼罩中的地平线成为全世界电视荧屏上司空见惯的画面。手持便携式空气污染检测仪的外国记者出现在北京的大街小巷,检查那里的烟尘水平。每个人似乎都迫不及待地向世人证明:这座城市的空气质量将是其举办世界最引人瞩目体育赛事的最致命的不利因素。

毫无疑问,北京正面临着巨大的挑战。对选手健康的担心和忧虑确实存在,而且也可以理解,特别对于那些参与自行车和马拉松等长距离耐力比赛项目的选手,这种担心的确也并非多余。

但在目前这种近乎疯狂的关注背后是西方世界的失忆。归根结底,尽管现在似乎很少有人能回忆起洛杉矶奥运会女子马拉松比赛临近结束时的戏剧性场景,一位瑞典选手在疲惫、闷热、或许还有空气污染的作用下步履蹒跚、踉踉跄跄,但有一点可以肯定,那就是在短短24年前,空气污染还是洛杉矶的一个主要忧虑。空气质量在紧随其后的巴塞罗那、亚特兰大、首尔和雅典奥运会上也曾出现类似的问题。

    The Brexit Surrender

  3. Murdoch's Last Stand?

    Rupert Murdoch’s sale of 21st Century Fox’s entertainment assets to Disney for $66 billion may mark the end of the media mogul’s career, which will long be remembered for its corrosive effect on democratic discourse on both sides of the Atlantic. 

    From enabling the rise of Donald Trump to hacking the telephone of a murdered British schoolgirl, Murdoch’s media empire has staked its success on stoking populist rage.

    The Dangerous Delusion of Price Stability

    Since the hyperinflation of the 1970s, which central banks were right to combat by whatever means necessary, maintaining positive but low inflation has become a monetary-policy obsession. But, because the world economy has changed dramatically since then, central bankers have started to miss the monetary-policy forest for the trees.

  5. Harvard’s Jeffrey Frankel Measures the GOP’s Tax Plan

    Jeffrey Frankel, a professor at Harvard University’s Kennedy School of Government and a former member of President Bill Clinton’s Council of Economic Advisers, outlines the five criteria he uses to judge the efficacy of tax reform efforts. And in his view, the US Republicans’ most recent offering fails miserably.

    The Holy Grail of Genetic Engineering

    CRISPR-Cas – a gene-editing technique that is far more precise and efficient than any that has come before it – is poised to change the world. But ensuring that those changes are positive – helping to fight tumors and mosquito-borne illnesses, for example – will require scientists to apply the utmost caution.
