海洋再生之年

发自牛津——海洋对全球重要性是怎么强调都不为过的。我们呼吸的氧气中有50%来自于海洋,海里的食材养活了几十亿人,还为另外数百万人提供了生计。大海是推动全球大气和热调节的巨型生物泵,也是水和养分循环的驱动器,还是减缓气候变化影响的最有力工具之一。总之,海洋是一个重要的盟友,我们必须尽全力去保护它。

鉴于我们目前所面临着诸多前所未有和不可预知的威胁,上述几点变得更为重要。虽然海洋已是减缓气候变化过程中不可或缺的一部分,吸收了自工业革命以来所产生的30%温室气体排放量和90%多余热量,但因此付出的代价也是巨大的。海洋酸化和气候变暖正在以惊人的速度推进,并且已经对一些我们最宝贵的海洋生态系统造成了严重影响——而且这种影响只会不断加剧。

今天,世界上广大大片正在经历着可能是有史以来最强的厄尔尼诺现象。由这一现象产生的恶劣天气——起源于太平洋地区,却影响着全球所有的海洋 ,预计今年将对超过6000万人产生不利影响,延续着去年的种种痛苦。这发人深省地提醒着我们:人类在自然和人为导致的地球系统冲击面前是何等脆弱。

    The Brexit Surrender

    European Union leaders meeting in Brussels have given the go-ahead to talks with Britain on post-Brexit trade relations.

  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.
