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。

    Empowering China’s New Miracle Workers

    China’s success in the next five years will depend largely on how well the government manages the tensions underlying its complex agenda. In particular, China’s leaders will need to balance a muscular Communist Party, setting standards and protecting the public interest, with an empowered market, driving the economy into the future.

    The Sovereignty that Really Matters

    The preference of some countries to isolate themselves within their borders is anachronistic and self-defeating, but it would be a serious mistake for others, fearing contagion, to respond by imposing strict isolation. Even in states that have succumbed to reductionist discourses, much of the population has not.

    Resurrecting Creditor Adjustment

    When the Bretton Woods Agreement was hashed out in 1944, it was agreed that countries with current-account deficits should be able to limit temporarily purchases of goods from countries running surpluses. In the ensuing 73 years, the so-called "scarce-currency clause" has been largely forgotten; but it may be time to bring it back.

    Trump’s Republican Collaborators

    Republican leaders have a choice: they can either continue to collaborate with President Donald Trump, thereby courting disaster, or they can renounce him, finally putting their country’s democracy ahead of loyalty to their party tribe. They are hardly the first politicians to face such a decision.

    How Money Could Unblock the Brexit Talks

    With talks on the UK's withdrawal from the EU stalled, negotiators should shift to the temporary “transition” Prime Minister Theresa May officially requested last month. Above all, the negotiators should focus immediately on the British budget contributions that will be required to make an orderly transition possible.

    Is Vladimir Putin Losing His Grip?

    In recent decades, as President Vladimir Putin has entrenched his authority, Russia has seemed to be moving backward socially and economically. But while the Kremlin knows that it must reverse this trajectory, genuine reform would be incompatible with the kleptocratic character of Putin’s regime.

    Rage Against the Elites

    • With the advantage of hindsight, four recent books bring to bear diverse perspectives on the West’s current populist moment. 
    • Taken together, they help us to understand what that moment is and how it arrived, while reminding us that history is contingent, not inevitable

    Don’t Bank on Bankruptcy for Banks

    As a part of their efforts to roll back the 2010 Dodd-Frank Act, congressional Republicans have approved a measure that would have courts, rather than regulators, oversee megabank bankruptcies. It is now up to the Trump administration to decide if it wants to set the stage for a repeat of the Lehman Brothers collapse in 2008.
