巴黎气候变化大戏

渥太华—12月的巴黎联合国气候变化会议将聚齐所有好莱坞大片精心设计的要素。“卡司”阵容强大:各国总统和总理当主角,包括示威者、防暴警察和各路媒体在内的“群众演员”当陪衬。剧本也许还没有杀青,但剧情已经泄露无疑:这一回与2009年哥本哈根谈判失败的结局不同,地球将获得胜利。

如此戏码颇令人着迷,但还远未敲定。世界将会知道,良好的初衷和艰难的谈判会取得成效。政府已经同意自愿减少温室气体排放,以使地球升温幅度不超过2℃。此外,一个“神转折”将是全球最大化石燃料公司——所谓的石油巨头——已经同意到2100年将净排放减少到零。这一目标将通过捕捉生产过程中的碳,将它们从大气中分离并埋入地下储存的方式实现。地球将得到拯救,经济将重获繁荣。音乐响起,大幕落下。

问题在于这是个虚构剧本,而不是纪录片。所需要的技术还没有发明出来,将排放减少到零根本不可能。此外,和好莱坞电影一样,巴黎会议的结果将在很大程度上由最大的金主决定。

    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.
