整治地质工程

纽约—气候变化给人类造成了前所未有的挑战,不出我们这一代人,生活质量就有可能大幅下降,并造成难以估量的长期危害。而由于解决这一可怕的地球挑战需要大胆的方针,对于世界急需做些什么来遏制全球气温升高幅度至前工业化水平以上1.5℃以内这一问题,已经有了各种讨论。

尽管最重要的工作仍然是降低温室气体排放,但联合国气候变化政府间委员会(IPCC)认为这是不够的。现在有些人认为我们还需要从空气中消除大量二氧化碳。也有人认为我们可能还需要将阳光反射会太空,为世界赢得更多时间降低和消除排放。

这两种办法合称地质工程。随着气候变化影响的加剧,越来越多的决策者、科学家和企业家开始比较严肃地考虑这一选项。

But although the United States will most likely continue its protectionist drift, other G20 countries should use the occasion to make a clear case for free trade.

    The Experts We Need

    Andrés Velasco

    Policy gurus spend too much time with others like them – top civil servants, high-flying journalists, successful businesspeople – and too little time with ordinary voters. If they could become “humble, competent people on a level with dentists,” as John Maynard Keynes once suggested, voters might identify with them and find them trustworthy.

    Don’t Feed the Donald

    Shlomo Ben-Ami

    For Japanese Prime Minister Shinzo Abe, appeasing US President Donald Trump is not so much a choice as a necessity: he must prove to Japan’s people and their neighbors, particularly the Chinese, that he knows how to keep Trump on his side. But Abe's strategy won't work with a US administration as fickle and self-serving as Trump’s.
