气候变化的真相

埃克塞特-许多人问我们对气候变化这门科学有多大的把握。对科学证据的最权威的审核可以在政府间气候变化专门委员会( IPCC )所做的工作中找到,此委员会最近的一项重要报告出版于2007年。我曾有幸在1988至2002年间任此委员会的科学评估小组的主席,或称为共同主席。

不同的国家的数百名科学家以撰稿者或评论者的身份参与了这些报告的撰写,这或许是历史上对科学问题进行国际评估的最全面和最彻底的一次。 1995年6月,就在苏格兰八国峰会召开前夕,世界上11个最大的经济体的科学院(八国集团加上印度、中国和巴西)发表了一项声明,认同了IPCC的结论,并敦促世界各国政府采取紧急行动,以解决气候变化问题。这是世界顶尖的科学家们发表声明所能达到的最强烈的程度。

不幸的是,强大的既得利益集团已花费了数百万美元来传播关于气候变化影响的错误信息。他们首先曾试图否认存在任何证实全球变暖的科学证据。而最近,他们基本上接受了这样的事实,即人为造成的气候变化的现象的存在,但认为其影响将不会很大,我们可以再“等等看” ,而且他们认为,在任何情况下,如果气候变暖发展到很严重的地步,我们总是能够解决这一问题的。

    Empowering China’s New Miracle Workers

    China’s success in the next five years will depend largely on how well the government manages the tensions underlying its complex agenda. In particular, China’s leaders will need to balance a muscular Communist Party, setting standards and protecting the public interest, with an empowered market, driving the economy into the future.

    The Sovereignty that Really Matters

    The preference of some countries to isolate themselves within their borders is anachronistic and self-defeating, but it would be a serious mistake for others, fearing contagion, to respond by imposing strict isolation. Even in states that have succumbed to reductionist discourses, much of the population has not.

    Resurrecting Creditor Adjustment

    When the Bretton Woods Agreement was hashed out in 1944, it was agreed that countries with current-account deficits should be able to limit temporarily purchases of goods from countries running surpluses. In the ensuing 73 years, the so-called "scarce-currency clause" has been largely forgotten; but it may be time to bring it back.

    Trump’s Republican Collaborators

    Republican leaders have a choice: they can either continue to collaborate with President Donald Trump, thereby courting disaster, or they can renounce him, finally putting their country’s democracy ahead of loyalty to their party tribe. They are hardly the first politicians to face such a decision.

    How Money Could Unblock the Brexit Talks

    With talks on the UK's withdrawal from the EU stalled, negotiators should shift to the temporary “transition” Prime Minister Theresa May officially requested last month. Above all, the negotiators should focus immediately on the British budget contributions that will be required to make an orderly transition possible.

    Is Vladimir Putin Losing His Grip?

    In recent decades, as President Vladimir Putin has entrenched his authority, Russia has seemed to be moving backward socially and economically. But while the Kremlin knows that it must reverse this trajectory, genuine reform would be incompatible with the kleptocratic character of Putin’s regime.

    Rage Against the Elites

    • With the advantage of hindsight, four recent books bring to bear diverse perspectives on the West’s current populist moment. 
    • Taken together, they help us to understand what that moment is and how it arrived, while reminding us that history is contingent, not inevitable

    Don’t Bank on Bankruptcy for Banks

    As a part of their efforts to roll back the 2010 Dodd-Frank Act, congressional Republicans have approved a measure that would have courts, rather than regulators, oversee megabank bankruptcies. It is now up to the Trump administration to decide if it wants to set the stage for a repeat of the Lehman Brothers collapse in 2008.
