LONDON – In 2009, the world’s rich countries pledged to mobilize $100 billion a year by 2020 to help poor countries tackle climate change. Since then, that promise has come to be regarded as a key test of the developed world’s resolve to do its part in the fight against global warming.
伦敦—2009年，世界发达国家承诺到2020年，每年要动员1,000亿美元帮助穷国应对气候变化。此后，这一承诺成为发达国家在遏制全球变暖方面做好分内事的决心的重要检验标准。
