When the US tries to tell China to reduce its carbon emissions, the people there have a pretty effective response. They usually say something like, "You heedlessly polluted the air for more than a century, starting with the industrial revolution. Why are you trying to hinder our industrial revolution?"
It's a pretty effective argument. So last week when Hillary went over there, she countered with a new approach. She said, something to the effect of, "You have a right to improve your standard of living, but we'd like you to follow greener practices so you don't make the same mistakes (regarding the enviroment) that we've made." It's a surprisingly humble approach.
