مجموعة الدول السبع الكبرى تتبنى إزالة الكربون

نيويورك ــ كان اجتماع قمة مجموعة الدول السبع الصناعية الكبرى في شلوس إلمان في جبال الألب البافارية بمثابة فتح كبير في سياسة تغير المناخ. فقد اتخذت الاقتصادات السبعة صاحبة أكبر دخل مرتفع (الولايات المتحدة، واليابان، وألمانيا، والمملكة المتحدة، وفرنسا، وإيطاليا، وكندا) القرار الثوري بإزالة الكربون من اقتصاداتها خلال هذا القرن.

للمرة الأولى في التاريخ، توافق الاقتصادات الغنية الكبرى على الحاجة إلى إنهاء اعتمادها على الوقود الأحفوري. وقد ارتفعت المستشارة الألمانية أنجيلا ميركل، والرئيس الأميركي باراك أوباما، وبقية زعماء مجموعة السبع إلى مستوى الحدث واستحقوا الإشادة العالمية القوية.

وقد سُجِّل هذا الفتح التاريخي في البيان الرسمي الختامي لقمة مجموعة السبع. فأولا، أكدت بلدان مجموعة السبع على أهمية الإبقاء على الارتفاع في درجات الحرارة نتيجة للانحباس الحراري العالمي عند مستوى لا يتجاوز درجتين مئويتين أعلى من المتوسط الذي ساد قبل بداية الثورة الصناعية (قبل عام 1800 تقريبا). غير أن الانحباس الحراري العالمي اليوم بلغ نحو 0.9 درجة مئوية بالفعل ــ أو نحو منتصف الطريق إلى الحد الأعلى.

    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.
