美国在应对气候变化上行动迟缓，看到学生们走在前端令人兴奋。我希望这将带动更多人认识到这些问题重要性——但是，我担心这怎么得到保证？SL

The US has been so slow to move on climate change, it's great to see students are taking a lead. I hope that it will trigger a wider acceptance of the importance of these issues -- but I wonder how this can be assured? SL

美国因没有签署《京都协议》而遭到永无休止的评击，事实上，除了日本以外没有任何一个发达经济国遵守所制定的二氧化碳排放指标，反而超标。《京都协议》对“发达”经济国而言，无非是一项裁定任何其他国家对污染物减派的计划，而却不包括西方国家和日本在内。然而，这并非是解决问题的方案。每个人毫无例外，都应当响应减排。在校园，学生们都纷纷响应这一措施，然而他们却是言而无信的一群。虚伪！

The US suffers endless criticism by not signing Kyoto, but none of the developed economies except Japan is even close to being within its agreed to CO2 emissions cap. In fact most of those countries are way over the limit. And Kyoto for "developing" economies is nothing more than an affirmative action program that lets everyone except the West and Japan emit every pollutant they want.
That is not the way to solve this problem. Everyone has to cut back, no exceptions.

As for campuses, students are great at shaking their fists at everyone else, but they arrive at the rallies in cars and holding hot lattes. Hypocrisy.
