适应气候之变

发自哥本哈根——对于我们这一代人来说,如何在阻止全球变暖和适应其多种效应之间取得恰当的平衡,是最重要,也最让人头疼的政策性问题之一。但即便如此,这一问题也常常为人们所忽略。

根据许多环保主义者的传统观念,我们应当首先尽全力去缓解全球变暖的态势,直到山穷水尽之时才把关注重点放在适应变暖的策略上。但这样做似乎是谬误——甚至不道德的——因为我们本可以借助适应性措施为人类和地球做出更多的贡献。

此外,上述传统观念也是与无法逃避的事实相对立的:因为无论我们做什么,都无法堵死全球变暖所的所有溢出效应。而如果我们准备不充分的话,全球变暖将引发更多的死亡和破坏,尤其是那些贫困国家和脆弱的社区更容易遭受其害。适应措施也将意味着能够从许多与全球变暖无关的灾难中拯救出更多生命。举个例子,当我们在社区中做好充分准备,以便在未来迎战更猛烈台风之时,我们实际上也在帮助他们更好的应对当今的极端性天气。

    The Next Battle in China’s War on Corruption

    • Chinese President Xi Jinping knows well the threat that corruption poses to the authority of the Communist Party of China and the state it controls. 
    • But moving beyond Xi's anti-corruption purge to build robust and lasting anti-graft institutions will not be easy, owing to enduring opportunities for bureaucratic capture.

    Putting Europe’s Long-Term Unemployed Back to Work

    Across the European Union, millions of people who are willing and able to work have been unemployed for a year or longer, at great cost to social cohesion and political stability. If the EU is serious about stopping the rise of populism, it will need to do more to ensure that labor markets are working for everyone.

    A Belt and Road for the Americas?

    In a time of global uncertainty, a vision of “made in the Americas” prosperity provides a unifying agenda for the continent. If implemented, the US could reassert its historical leadership among a group of countries that share its fundamental values, as well as an interest in inclusive economic growth and rising living standards.

    How Best to Promote Research and Development

    Clearly, there is something appealing about a start-up-based innovation strategy: it feels democratic, accessible, and so California. But it is definitely not the only way to boost research and development, or even the main way, and it is certainly not the way most major innovations in the US came about during the twentieth century.

    Preparing for the Trump Trade Wars

    In the first 11 months of his presidency, Donald Trump has failed to back up his words – or tweets – with action on a variety of fronts. But the rest of the world's governments, and particularly those in Asia and Europe, would be mistaken to assume that he won't follow through on his promised "America First" trade agenda.
