应对气候变化对健康的益处

利马——政府往往认为气候变化的解决成本太过昂贵。事实却是气候变化代价太高、不容忽视。这解释了为什么世卫组织(WHO),举例来讲,将预防灾难性气候变化与减少空气污染所带来的“直接健康效益和成本节约”联系在一起

统计数据反应的情况异常严峻。空气污染2012年造成七百多万人早亡——占全球早亡人数的八分之一,而烟草造成的早亡人数也才不到六百万而已。

最大的损害来源是人们所说的PM2.5微粒,这种微粒直径还不到2.5微米。它们能够深入肺部造成极大的破坏,诱发炎症、癌症、呼吸道感染,或者通过进入血液诱发血管变化,诱使心脏病和中风发作。

    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.
