全球变暖的肮脏秘密

上周欧盟实际上宣布它拯救了这个星球。随着欧洲委员会主席若泽·曼努埃尔·巴罗佐宣布欧洲将在气候变化方面发挥主导作用,欧盟承诺到2020年时将二氧化碳排放减少20%,达到低于1990年的水平。当然,鉴于欧盟已经在《京都议定书》中承诺到明年减排8%,所以这个新目标似乎显得有些不够宏大。此外,由于欧盟继续坚持一些让《京都议定书》不能正常产生实效的根本性问题,它所迈出的新步伐可能更是不智。

当然,人为的气候变化是实实在在的,而且也会造成严重的问题。但目前这种“在为时已晚之前减少排放”的思维方式忽略了这样一个事实:我们没有明智的短期解决方案。

这似乎就是我们专注于像《京都议定书》这一类的让自我感觉良好的方式的原因。它的根本问题从来就是既好高骛远,又不符合环境逻辑,还代价不菲。它所要求的减排量是如此之高,以至于只有寥寥数国可以做得到。

    Angela Merkel’s Endgame?

    The collapse of coalition negotiations has left German Chancellor Angela Merkel facing a stark choice between forming a minority government or calling for a new election. But would a minority government necessarily be as bad as Germans have traditionally thought?

    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.

    The Platform Economy

    While developed countries in Europe, North America, and Asia are rapidly aging, emerging economies are predominantly youthful. Nigerian, Indonesian, and Vietnamese young people will shape global work trends at an increasingly rapid pace, bringing to bear their experience in dynamic informal markets on a tech-enabled gig economy.

    Profiles in Discouragement

    One day, the United States will turn the page on Donald Trump. But, as Americans prepare to observe their Thanksgiving holiday, they should reflect that their country's culture and global standing will never recover fully from the wounds that his presidency is inflicting on them.

    How Women Shape Coups

    In Zimbabwe, as in all coups, much behind-the-scenes plotting continues to take place in the aftermath of the military's overthrow of President Robert Mugabe. But who the eventual winners and losers are may depend, among other things, on the gender of the plotters.

    The Abnormality of Oil

    At the 2017 Abu Dhabi Petroleum Exhibition and Conference, the consensus among industry executives was that oil prices will still be around $60 per barrel in November 2018. But there is evidence to suggest that the uptick in global growth and developments in Saudi Arabia will push the price as high as $80 in the meantime.

    The Saudi Prince’s Dangerous War Games

    Saudi Arabia’s Crown Prince Mohammed bin Salman is working hard to consolidate power and establish his country as the Middle East’s only hegemon. But his efforts – which include an attempt to trigger a war between Israel and Hezbollah in Lebanon – increasingly look like the work of an immature gambler.
