Yes, the world needs to address global warming (mainly through higher investments in green research and development, and by promoting exploitation of cheap, less-polluting shale gas). But global warming will cause damage worth possibly 1-5% of GDP by the end of the century, when the UN expects developing-world incomes to have risen by 1,400-1,800%.
是的，世界需要解决全球变暖问题（主要通过加大对绿色能源研究和发展的投资，促进廉价和低污染页岩气的开发）。但全球变暖问题将在本世纪末导致大概价值占GDP1~5%的损失，而联合国预计那时发展中国家的收入已增长了1400~1800 %。
