A striking fact about climate change is that there is little overlap between the countries that are most vulnerable to its effects – mainly poor countries in the South that can ill afford to deal with the consequences – and the countries, like the US, that are the largest polluters. What is at stake is in part a moral issue, a matter of global social justice.
有关气候变化的一个惊人事实是：在气候变化中受害最深的国家¾主要是那些承担不起气候变化后果的南部贫困国家¾与以美国为首的头号污染国几乎是完全不同的两大阵营。部分问题牵扯到道德层面，涉及到全球社会是否公平。
